Preparing fabric for cutting and cutting. Fabric decating Technology for cutting and sewing pile fabrics

Some fabrics shrink when washed. Materials made from natural fibers, such as linen, cotton, wool, silk, shrink especially strongly. The rate of fabric shrinkage can be from 1.5 to 10% (it is individual for each type of fabric). This means that when curtains are 2 m 50 cm high, after washing they can be shortened by 3.7-25 cm. forced shrinkage before cutting. Accordingly, you need to buy material with a margin for shrinkage. Do not forget about this if you sew curtains with your own hands.
Decating fabric is a wet-heat treatment in order to prevent shrinkage of the fabric during the sewing and operation of the product. For decating fabric at home, a regular iron is used. It makes sense to buy special devices that exist for these purposes - steam generators if you sew a lot.
Cotton, linen, artificial fabrics should be dipped in warm water for a few minutes, squeezed out slightly without twisting, then it is best to pull it out on a stick or crossbar. Be aware that cotton fabrics can shed. This is especially true for red and green colors. The more shedding the fabric, the less warm the water should be. A slightly damp cloth is ironed from the inside out. In this case, the iron is carried out along the shared thread. The pieces of fabric for sewing curtains have an impressive length, so thoroughly wash the floor before ironing the fabric.
Silk and woolen fabrics should be moistened by wrapping them in a soaked and wrung out towel (or sheet), left in this position for 2-3 hours. After the fabric is ironed necessarily through the iron.
On some fabrics made of artificial, synthetic and mixed fibers, creases and creases formed during inaccurate ironing cannot be removed. This is rare, but you need to be aware of it.
Corduroy, velvet, plush and other pile fabrics do not decant. If there is a need for ironing, it is done on weight. You can lay a pile fabric on a fabric with the same pile (i.e. pile to pile) and lightly, through a damp iron, almost without touching the fabric with an iron, just steam the fabric.
artificial and genuine leather, lacquer, "wrinkled" fabrics, bologna, are not subjected to decatization.
In addition, some types of curtain fabrics may shrink gradually, with each wash a little. In this case, you need to either make additional allowances along the bottom edge when sewing, due to which, if necessary, it will be possible to increase the length of the curtains, or choose longer curtains immediately so that after washing they take desired shape. By the way, now it is fashionable to make curtains of such length that they can be laid on the floor with beautiful draperies. In this case, shrinkage of the curtain material during washing is not a problem.

Before cutting the product, it is necessary to prepare the fabric for cutting.

Many fabrics have the property of shrinkage. To ensure that the product does not lose its original shape and size during wear, the fabric should be decanted.

Woolen fabrics(dress) usually decant through a wet iron (piece thick fabric, preferably linen) in the shared direction. In this case, you should not drive the iron for a long time, as the fabric can become the most rigid. The fabric is then allowed to cool and dry.

Single-sided woolen and crepe fabrics are moistened by regular spraying or spraying. Wrapped in a sheet and left for several hours, after which the fabric is ironed with a not very hot iron from the inside along the shared thread.

staple fabrics and artificial silks are best dipped in slightly warm salted water for 15 minutes, starched, gently squeezed out without twisting, then wrapped in a sheet for 2-3 hours. Iron the fabric from the wrong side, with a not very hot iron.

cotton fabric moistened in warm water, squeezed, dried and ironed.

It should be remembered that some fabrics (wool, velvet, synthetic) cannot be moistened, as stains or wrinkles remain on them, which do not disappear even after ironing. Therefore, before decating the fabric, it is necessary to check on a piece how it reacts to moisture.

1. Preparing the fabric for cutting.

Determine the fiber content of a fabric.

Decat the fabric to prevent subsequent shrinkage.

Determine the direction of the grain thread on the fabric, the front and back sides, the direction of the fabric pattern and its nature, in order to take all this into account when laying out the patterns. Check for defects.

Iron the fabric.

Bend the fabric along the shared thread in the middle with the front side inward, equalizing the pattern, chop off.

Align the cross section of the fabric with a square.

2. Laying out the details of the pattern on the fabric.

When laying out patterns, it is necessary to take into account some properties of the fabric. It is easier to cut out from hard, elastic fabrics than from light, loose and sliding ones. When laying out, pay special attention to fabrics with a one-sided direction of the pattern. Here it is necessary to ensure that on all the details of the product the pattern is directed in one direction. In pile fabrics, the direction of the pile and shade are checked. When cutting from velveteen and velvet, the details of the patterns are laid out sequentially in the direction of the pile from the bottom up.

When cutting products from flannel or baize, place the details of the patterns in the direction of the pile from top to bottom, then while wearing the pile will not rise. On fabrics with stripes and a cage, arrange the details of the patterns so that at the junctions of the details (at the seams) the strip or cage matches in color, width and runs exactly in the middle of the front and back.

In terms of size, cells in tissues can be small, medium and large. In addition to size, they differ in color, size of squares, width and order of alternation of stripes. If in the drawing of a tissue cell one can find a midline that divides the cell into two equal parts in all directions, such a checkered tissue is called symmetrical.

When cutting, the line of symmetry must be aligned with the middle line of the pattern.

The layout of patterns on the fabric is carried out in two ways:

in the fold - the fabric is folded in half along the length with the front side inward;

in turn - the fabric is turned in width.

Lay out large parts on the fabric, starting from the shelf, stepping back from the cut by the amount of the seam allowance.

Patterns on fabric with a directional pattern should be in the same direction. If the fabric has a large pattern, it is necessary that the right and left side were symmetrical

The direction of the warp threads on the pattern should match the direction on the fabric.

Pattern details are arranged so that the layout is economical.

The lines along which the cutting will be made and the control points are drawn with sharpened chalk or soap.

III. Presentation of new material with a presentation.

Before cutting the product, it is necessary to prepare the fabric for cutting.

Many fabrics have the property of shrinkage. To ensure that the product does not lose its original shape and size during wear, the fabric should be decanted.

Woolen fabrics (dress fabrics) are usually decanted through a damp iron (a piece of dense fabric, preferably linen) in the shared direction. In this case, you should not drive the iron for a long time, as the fabric can become the most rigid. The fabric is then allowed to cool and dry.

Single-sided woolen and crepe fabrics are moistened by regular spraying or spraying. Wrapped in a sheet and left for several hours, after which the fabric is ironed with a not very hot iron from the inside along the shared thread.

Staple fabrics and artificial silks are best dipped in slightly warm salted water for 15 minutes, starched, gently squeezed out without twisting, then wrapped in a sheet for 2-3 hours. Iron the fabric from the wrong side, with a not very hot iron.

Cotton fabric is moistened in warm water, wrung out, dried and ironed.

It should be remembered that some fabrics (wool, velvet, synthetic) cannot be moistened, as stains or wrinkles remain on them, which do not disappear even after ironing. Therefore, before decating the fabric, it is necessary to check on a piece how it reacts to moisture.

Preparing fabric for cutting.

Determine the fiber content of a fabric.

Decat the fabric to prevent subsequent shrinkage.

Determine the direction of the grain thread on the fabric, the front and back sides, the direction of the fabric pattern and its nature, in order to take all this into account when laying out the patterns. Check for defects.

Iron the fabric.

Bend the fabric along the shared thread in the middle with the front side inward, equalizing the pattern, chop off.

Align the cross section of the fabric with a square.

How to sew linen? This fabric is rightfully considered the most environmentally friendly material. Clothes made from linen, the best choice for hot climates! Sewing linen is not difficult, but the preparation for work and the care of this fabric have their own characteristics.

We will talk in detail about the properties of linen and how to sew linen with your own hands.

linen features

Why is linen so popular? This fabric obtained from flax fibers has remarkable consumer properties! Linen perfectly absorbs moisture and dries quickly; in hot weather, linen clothes reduce body temperature by several degrees. Linen is not electrified, resistant to pollution and even has antiseptic properties! Linen fabrics will serve you for a very long time. Over time, linen does not turn yellow, but becomes lighter and softer.

The main disadvantage of 100% linen is wrinkling and a tendency to both shrink after washing and stretch during wear. To compensate for these shortcomings, mixed fabrics are produced. Linen is mixed with silk, viscose, elastane, wool.

Plain weave of natural linen is well recognizable, it is also distinguished by the presence of thickening on some threads, up to small knots. The fewer such blotches, the better quality linen you hold in your hands. Before buying, be sure to run your hand over the fabric, if possible, it is desirable to attach a cut to the body. Some types of linen can prick and leave an unpleasant sensation on the skin, although most often linen fabrics, on the contrary, are very pleasant to wear.

Please note that linen will definitely shrink when washed. Therefore, buy a cut with a margin, about 10% more than recommended for your model.

Model selection

Linen fabrics are suitable for almost any clothing.

Please note that during wear, linen can stretch a lot, especially in places prone to bending (for example, knees). Therefore, you should not sew products of an adjacent silhouette from linen or use a lining.

Cutting preparation

Like all natural materials, linen fabrics need obligatory decatization! Light plain fabrics can be soaked in hot water, and fabrics of dark colors and with a pattern - in water with a temperature of up to 40 degrees. If in the future you plan to wash the product in the machine, wash the fabric in the same way.

To avoid warping, we recommend basting or topstitching the fabric with the right side folded inward. Do not use spin to avoid strong creases in the fabric. Then dry the fabric, straightening it as much as possible. Iron slightly damp linen with a hot steam iron.

How to sew linen with your own hands? Linen fabrics are easy to work with. They are easy to cut, grind and they lend themselves well to the WTO.

The edge of linen fabrics often frays a lot, so cut out pieces with slightly larger allowances. Process the allowances as quickly as possible. If your fabric has a loose structure, it is worth strengthening the place where the zipper is embroidered with non-woven fabric.

Check on a piece of fabric how the seam behaves and if the fabric near the line “creeps”, glue the seams with a narrow strip of interlining. The line should go straight along the interlining, stepping back 1-2 mm from its edge.

Linen care

As already mentioned, linen products stretch during wear, but restore their shape after washing. Wash linen at the temperature at which it was decanted (or specified by the manufacturer).

Colored fabrics may shed, so wash them separately at temperatures up to 40 degrees with a detergent for colored fabrics. Do not spin at high speeds and dry flat.

Wet linen should be ironed at high temperature using steam.

The fabric is an interlacing of equity threads (main) running along the edge, and transverse (weft) threads. The direction of the thread in the fabric can be determined by stretching and by sound: the fabric is more difficult to stretch along the lobar thread, and when the fabric is twitched along the lobar thread, the sound will be more distinct, and it will be muffled along the transverse thread.

There are a lot of weaving patterns, but there are three main ones: linen, satin (satin) and twill.

In plain weave, the warp threads alternate with the weft threads, so the surface of the fabric is smooth, matte, the same on the front and back sides.

In plain weave printed fabrics, the front side is determined by the brightness and clarity of the pattern, and in plain-dyed fabrics - by the quality of processing (there are fewer knots and villi on the front side). Plain weave produces: most cotton fabrics - chintz, calico, linen and some dress fabrics; linen fabrics - linen, cushioning; many types of silk fabrics - crepe de chine, crepe georgette, linen, etc.; some woolen dress and suit fabrics.

In satin (satin) weave, the front side of the fabric, in contrast to the wrong side, is smooth and shiny. Glitter is formed as a result of the fact that one weft thread overlaps 4-8 warp threads. If one warp thread overlaps several weft threads, then this weave is called satin.

Satin weave produces such fabrics as satin, satin, crepe-satin, lining and some others.

In a twill weave, weaves form on the fabric in the form of diagonal stripes running from one edge to the other. On the front side of the fabric, diagonal stripes are directed from bottom to top to the right. Twill weave produces: cotton fabrics - bumazeya, tights, twill, paper cashmere, etc.; woolen - cashmere, boston, gabardine, etc.: silk - lining, a number of dresses, raincoats.

When cutting, it is necessary to take into account the properties of the fabric: chop off the sliding one with pins, and if it is loose, increase the allowance for seams and stocks and be sure to overcast the cuts - the cut edges of the parts. From wrinkled fabrics and fabrics with a loose weave of threads, it is not recommended to sew tightly fitting products. Products from fabrics of increased extensibility should be made on a lining.

In order for the finished product to retain its size and not deform when worn, the fabric must be decatered before cutting, i.e. treat with water vapor. To do this, wet the cotton fabric in a small amount of warm water with the addition of vinegar or salt, without squeezing, dry and iron from the wrong side; soak the linen fabric for a short time in hot water, dry and iron on the front side; soak a fabric made of artificial fiber in slightly warm water with the addition of vinegar, wring it out slightly and roll it into a dry sheet, and then iron it from the inside while still wet; roll a woolen or silk fabric tightly into a damp, well-wrung out sheet and leave it in this position for 5-8 hours or hold the fabric over hot steam, and then iron it from the wrong side with a hot iron through an iron.

In all these cases, iron any fabric only along the shared thread. After decathing, the fabric should dry completely. Very thin fabrics can be ironed with a hot iron through a moistened ironing iron without pre-moistening them.

At the cut edge of the fabric intended for sewing the product, pull out the transverse thread (weft) and align the edge along it. If the fabric is skewed, moisten it and pull in the desired direction, and then iron along the shared thread.

The consumption of fabric for the product depends on the model and size of the figure. The more complex the model, the greater the fabric consumption. The complex elements of the model include wide skirts, raglan and one-piece sleeves, draperies, figured undercuts, reliefs, coquettes, collars, pockets, inlays, flounces, frills, frills, molds, etc. It is necessary to take into account the width of the fabric, the direction of the pile and pattern, so how to adjust the pattern will require additional fabric along the length, regardless of its width, and the percentage of shrinkage (mainly along the longitudinal thread) depends on the fibrous composition of the fabric, averaging for: cotton fabric 3-5%, woolen and semi-woolen 3-4% , natural silk 2-3%, artificial silk 4-8%, staple fabric 4-6%. Synthetic fabrics practically do not shrink.

To determine the consumption of fabric, mark its width on a sheet of paper and lay out the details of the pattern of the product, taking into account the direction of the grain thread indicated on the details, allowances for seams and stocks, fitting the pattern and shrinkage of the fabric.

For cutting, fold the fabric in half along the transverse thread (along the weft) or along the shared (warp) side inward, depending on the width of the fabric and the characteristics of the model, adjusting the pattern. First, place the large details of the pattern (back, shelf, etc.), and then between them - small ones, strictly following the coincidence of the direction of the grain thread on the fabric and on the details of the pattern (Figure 18). This is important because, as already noted, the fabric along the longitudinal thread stretches much less during wear, shrinks less during washing, dry cleaning and ironing than along the transverse thread. The direction of the shared thread on the details varies depending on the model - they can also be cut along a transverse, oblique thread. Having laid out the details, check with a ruler or centimeter tape the correct layout of the pattern details along the shared thread.

On plain-dyed fabrics or with an indistinct pattern, for economical cutting, pattern parts can be laid out in different directions, observing the direction of the grain thread and the distance for seam allowances. On the rest of the fabrics, place the details with the upper cut in one direction (except for facings). On pile fabrics or with a clearly defined one-sided pattern, with an asymmetric cage or stripe, mark the direction of the pattern or pile on the wrong side with a chalk arrow and make sure that it is not disturbed when laying out the details of the pattern. IN finished goods from flannel, baize, cotton suede, the pile should be directed from top to bottom, so that when worn, a smooth surface of the fabric is maintained, and in products made of velvet, panne velvet, velveteen - from bottom to top, so that the color of the fabric is more juicy. Also mark the detected fabric defects with chalk and place the parts so that the defect is not in a visible place of the product or the fabric area with the defect does not fall under the pattern when cutting.

When laying out the details of the pattern on fabrics with a large, clearly defined pattern, you need to take into account that it must be combined in the side, front and back seams, and also determine the pattern (check or strip) that is most suitable for placing the middle of the product details (back. shelves, sleeves, etc.). In addition, it is necessary to monitor the coincidence of the pattern in paired parts, tucks, etc. Sometimes, in order to save fabric, it is possible to cut out parts with wedges or extensions, placing them in inconspicuous places: the lower halves of the sleeves or shelves at the side seams, on the lower collar, facings, selections below the lapel line, on the belt at the side seam. If extensions have to be made in prominent places, then they should be used as fittings. For example, the back can be made in two parts with a seam in the middle or in three parts on the yoke. Details such as the lower parts of the collar, cuffs, leaflets, facings for the neck and bottom of the sleeves should be hemmed so that the direction of the grain thread on these details, as well as on the main ones, coincides.

Having placed all the details of the pattern on the fabric, pin them with pins, circle the contour, shaped lines and control marks with finely sharpened tailor's chalk or a dry bar of soap (soap does not crumble and does not stain the fabric during work, the soap trace quickly disappears under a hot iron). Give allowances for seams: 0.7 cm along the sprout and neck, 1.5-3 cm along the shoulder and side sections, 1-1.5 cm along the armhole, 3-4 cm along the waist, 3-8 cm along the bottom of the product, 1-1.5 cm along the sleeve hem, 2-3 cm along the back and front sections of the sleeve, 0.7 cm along the bottom of the sleeve. ). Place parts that are not cut in the middle (back, front, collar, etc.) on the fabric so that their middle runs along its fold.

After trimming, remove the details of the pattern and, so that the fabric does not move, fasten it with pins. Place the pins on the details of the product at a distance of 3-5 cm from the chalk lines or the fold of the details. The distance between the pins is 12-15 cm in straight sections and lines and 8-10 cm in curly ones (Figure 1b, c).

If there are seams in the middle of the back or front, then sweep the details with running stitches, and lay snares along the contour, shaped lines and control marks, clearly marking the corners and roundings. Along these lines, the product will be swept and then sewn on the machine. Mark the middle of the solid parts (back, front, skirt panels) with interlining stitches. When cutting parts with asymmetric elements, lay the fabric on the table unfolded face up, place the parts on the fabric also face up. Circle the contour and shaped lines with chalk, and then lay running stitches with a thin thread: 2-3 cm on straight sections, 1-2 cm on curly sections, 0.5-1 cm on curves.

When cutting the fabric, do not move it and do not lift the details of the cut. The part should be located to the right of the scissors, and the cut fabric should be held with your left hand. Do not cut darts on the details.

When cutting in a straight line, it is necessary to ensure that the ends of the scissors move strictly along the chalky line of the seam allowance, and try to cut with the middle of the cutting part of the scissors. When cutting along smooth lines, on the contrary, it is necessary to cut with the ends of the scissors. The narrow end of the blade should be under the fabric. The exception is lace fabrics, as the narrow end of the scissors can get into the pattern and deform it. It is convenient to cut with scissors from yourself straight or from yourself to the left.
