Even the master with many years of experience can be mistaken, identifying the face and involves the cloak, lining or, buying fabrics for tailoring wholesale. And this entails at least the overrun of the fabric, and as a maximum of a spoiled line of finished products. To avoid the emergence of such situations, it is enough to know simple rules Recognition of facial and invalid sides from the online store BOSFOR TEXTILE when sewing quality outerwear and other products.

Rules, how to determine the fabric fabric quickly and accurately?

  • Factory packaging. If you buy fabrics in bulk, rolls, right from the factory, to determine the face will be easy. Technical standards of domestic enterprises provide for wool fabrics so that the front side is located inside the roll. Lining and silk fabrics are wounded to the roll upside.
  • Good lighting. Daylight does not make it possible to detect the production defects of the fabric, explicitly distinguish the shades of color and prints, see the difference in the structure of the tissue, in the weakening of the threads. Use an additional light source. For convenience, place the material at the level of your eyes, placing the facial next to the involving side.
  • "Disadvantages" - hide inside. For the face of the material is characterized by better, clean software, exterior decoration. The extension can hide all possible defects.
  • Picture. A rich and smooth pattern, a juicy tint of the color, the facial part of the material is distinguished. In fabrics with a smooth surface (especially this is important when you are looking for) the outer side is glittering, and the inner - matte.

  • Edge. The most difficult thing to guess how to determine the front side of the cloth smooth. But it is also possible if you carefully examine punctures next to the edge. The bulge of holes, as well as well-looking threads point to the exploration of the material to your face.
  • Weaving. You can learn the weaving of the web (cloak or fingertip) using a thorough inspection. Lost is clearly seen that the facial part of the fabric is smoother, less covered with a pile, and the rank is rough. In addition, in the tissues obtained by a sanching interweight (for example, lining) from the face viewed a relief diagonal, located on the right from top to bottom. From the inside - on the contrary.
  • Pattern. On fabrics with a pile (for example, a fingerboard "Bohemia"), the facial surface is found at its height. The outer side is characterized by a higher and even pile height, inherent in thin veins, can be found with production flaws.


How to determine the wrong tissue?

If, when checking all the ways, it did not work out, where the face, and where is the exhaust, you can apply a couple of express methods:

  • often in the mixed fabric canvases on the face use a more expensive and natural thread. In the half-walled fabrics from the face noticeable woolen yarn etc.;
  • withdrawal with impregnation, simply determine with a drop of water. With the inside, water vagls, absorbed into the fabric, from the face - easily flows, not leaving traces on the material.

Remember, in certain fabrics face and painted side The same color or structure. They are called two-chain. Such materials have a working surface on both sides. For example, Cantionics lining fabric, viscose double-sided and sports grid from the directory of our online store.

It should also be noted that there are cloaks that do not cause issues with the definition of the parties, thanks to the special coating, as a rashboard of Memori oil or milk.

If you disassemble the face and invalid, you did not come out, we recommend cutting all the details of the product on one side of the tissue. Before the start of work, mark the face with chalk, for example, when using interstitial attacks. With such marks, the details will be much easier to negotiate, make welcomes, valves, bar and pockets.

And the last, but important advice in the topic: Buying fabrics for sewing clothes wholesale in the online store Bosphorus Textiles, you can get a professional advice not only in the establishment of the face and inside the fabric, but also in the selection of accessories, threads, lining for your products!

Before buying material for sewing, you should know how to determine the facial side of the fabric over the edge, drawing, pile, etc. appearance Products will depend on its choice. But the most important thing is what to do is to determine the parties before the product revealing. This important thing is not recommended to do in the evening and with very bright artificial lighting, as it distorts reality. In the morning it may turn out that the choice was wrong, and the wines of the whole illusion.

How to determine the facial fabric

Having come to the store or considering the tissue on the things available at home, it can be noted that in appearance they differ quite strongly. Their difference can be both by the type of surface (openwork, embroidered, with a picked pattern), and by type of color (multicolored, printed, smoothly painted or bleached). There are also jacquard multicolored fabrics - tapestry. Such fabrics are considered complex in production, but it is very simple to identify the front side.

Many know that depending on their fibrous composition of the fabric pass different finishes. Natural cuts, whiten, face. All finishing is made on one side of the product - facial. With weavion, all irregularities and nodules are hiding on the wrong side, so with the front side all the fabric are smoother and bright, with a clean surface or, on the contrary, with a relief, convex pattern. To the touch, she will also be different (smooth and pleasant, has a clearer, relief drawing).

How to distinguish the front fabric from the inside

It should be known that the fabrics are one-sided and bilateral. An invalid and front side of one-sided fabrics are quite different. Duplex differ slightly or not at all. Sometimes both sides of the canvase can sometimes be used.

Facial side of different types of fabrics

So, how to determine the front side on the tissues of monophonic and not only:

  • Fabric with pattern printing: where brighter, there is a facial side.
  • Fabric with pattern (wounded): On such fabrics, the face pattern will be clearer and convex.
  • Fabrics with satin and satin weave. With the front side, these interlacing have a more shiny and smooth surface, the rutter goes at different angles, have a beautiful appearance. With inside, these fabrics are more similar to the canvas having linen weave.

  • The fairytale fabric, the Metal Thread "Lurex", applied with embossed, coating "under the skin", embroidery. In the tissues of mixed raw materials, the front side will always look "more expensive." In all cases, the painting side of beauty will exceed the facial. Embroidery threads will lie smoothly, without nodules, stitch covers the drawing completely.

More complex features of the face definition

Not all pile fabrics have a pile from the front side. The papers has a pile side - an exhaust, but usually this fabric has a printed pattern and a beautiful smooth surface from the face. But velvet, velvet, velor is beautiful on the side of the pile, so it is difficult to make a mistake in the definition of the front side. For example, a monophonic flannel refers to double-sided tissue - it has the same coloring, linen interlacing and villus on both sides.

A pile of Drapa has a pile, and it is located in one direction, or there is a dense lobby pattern. The fabric of this type from the wrong side can have a more loose weave.

To the cloth, this also applies. It, in most cases, is strongly crushed, which leads to some difficulties in the process of determining the front side. It is necessary with the effort to spend your fingers from different sides and in different areas, and the party where the pile is less dense, less high-quality, and there is an exhaust.

What if all the above methods of how to determine the facial side of the tissue did not give an answer? You can identify the side of the surface quality of matter. That is, the facial will be the party where the surface of the fabric does not have flocks, nodules, it is smoother. The presence of flocks is inherent only with natural fiber tissues.

To determine the presence of villi or brightness of the color, the matter should be reduced to the eye level and look at the light. If it was not possible to detect pronounced defects, then such a tissue can be attributed to bilateral.

Face definition of the side of the edge

You can determine the facial side of the fabric over the edge (both by its quality and holes on it). The edge will be better with the front side. When the tissue in the finish process is tensioned to the calendar, holes remain. It is believed that they should be at the top of the convex side, and concave - from the wrongness, but in practice it happens and vice versa.

Conclusion

Before opening complex tissues, it is necessary in several places, preferably in intercourse, designate the front side. It is usually done by chalk, drawing cross. It is important not only in order not to confuse the parts during the steps, but also for stringing planks, fees, valves, etc.

If all visual methods were moved, and the doubts did not disappear anywhere, do not forget about the tactile sensations, because the sensitivity of the fingers will never let down.

It happens that the seamstress knows that the sewing side wants to choose an involnee side (the one for people who created fabric, and is invalid), because it seems to her the opposite more attractive.

And if it never managed to choose one of the sides with complete confidence, then besides the owner finished product No one knows about it because everything is coming in comparison.

Definition of facial face.

To determine the facial side of the fabric, it is primarily necessary to find out what is the type of weave the threads in this tissue. After all, the fabric consists of two systems of threads intertwined at right angles: longitudinal threads - bases and transverse - duck.

The main weaves are linen, diagonal or twenty, satin or satin. Linen weave is the most common. In this case, one duck thread overlaps one base thread. This interlacing has the same surface on both sides. Sitz, bosses, most laid fabrics, dresses made of natural and artificial silk, wool are produced with such a weave. The front side of the smooth-colored tissues with linen is considered the one that looks cleaner, better finished, has less gun. In the printed fabrics on the front side the picture is applied.

Diagonal, or a sanches, forms a strip on the tissues (Rubber). At the same time, the weave one thread of the duck overlaps two or three filaments of the base or vice versa. With such a weave, cashmere, boston, chevot, lining sarza, etc. are produced. Single weaving fabrics with strolling in the opposite direction sometimes give a grade. The front side in these fabrics will be the one where the rutter goes down to the left up right.

In satin, or satin weave, the fabric has a smooth, shiny surface. In such a weave of satina, one thread of a duck overlaps from 4 to 8 threads of the base, atlas on the contrary - one thread of the base overlaps from 4 to 8 yarns. The front side of the fabrics is brilliant, and the wrong one is matte.

In addition to the above-mentioned types of weave, there are other derivatives of them, as well as combined.

Determination of equity and transverse threads.

Properties of equity and transverse threads are different. The equity threads give a greater shrinkage than transverse. It is caused by the fact that the filaments of the base with weavion are tightly tight, and the filaments are free to go freely. Therefore, getting under the action of moisture and steam, the filaments of the foundations acquire their original position, that is, the filament of the duck is enveloped, and the tissue in length is reduced (sits). The fabric shrinkage is deliberate, providing a positive effect - this is the so-called decatting. With random effect on the failed fabric, the product also gives shrinkage, but this is a negative phenomenon.

Some techniques for determining the equity and transverse thread: the equity thread goes along the edge; In the sample on the stretching, the equity thread is almost not stretched, but transverse more stretch; On the fabric with a wrapal of nosch, in most cases is located on the equity thread; In the sample on the clearance it is clear that the equity threads lie more evenly.

Methodical development of the lesson "Determination of the facial and irons of the materials. Properties of tissues."

- - True, let's get to the lesson for receiving new knowledge and formulate the topic of our current lesson "Facial and auto fabric side. Properties of fabrics.»

(Question class)

What do you think. Why do the guys do we need to know it?

(students offer various options for answers, the teacher asks, the necessity, leading questions, gives some comments,)

Message of new material (+ p / p)

Facial and irons.

The cloth - textile cloth Made on weaving machine.

The fabric consists of two intertwined threads located perpendicularly. The system of threads running along the tissue are calledthe basis , and the system of threads located across the fabric -duck .

The surface of the fabric depends on the features of the tissue finishes.

And now, take in the hands of the fabric samples, and look carefully at them ...

Signs of definition of facialand Pour Fabric Pide(§3, p.15-16)

  • Printable.Fabric with printed pattern drawing on the front side of the fabric is brighter and clear.
  • On the surface. In smooth painted fabrics, the front side is smoother, and the wrong one is more durable. To determine the fluffy, it must be considered at the level of the eye.
  • By drawing of weaving weave. In the tissues of the sarrenchy, on the front side, the rutter goes up and left to the right.
  • In shine. For example, satin fabric is more brilliant than satin.
  • Accuracy. The number of nodules, looping, the ends of the torn threads on the front side are less than with the wrong one.
  • Park. On the front side of the velvet or Velvet a long pile. On the involving side, the surface is smooth or a pork short. In Drapah, the pile is located more ordered NM facial side, and the wrong side has a slightly non-accurate appearance.
  • On the edge. At the edges of the fabric at the edge there are punctures. On the front side, the fabric in places of punctures is more convex.
  • Mixed fabrics. Finishing threads are removed on the front side. For example, in the passage, the brilliant metallized thread-lobster is removed on the front side.

Distinguish one-sided and double-sided tissue. Remember that the definition of the facial and invalid side plays an important role in walking clothes.

In one-sided tissues, the facial and auto side differ sharply from each other. In double-sided tissues, this difference is practically imperceptible, i.e. And the other parties can be used with string.

Question. What does the correct definition of the face of the material affect the correctness of the facial side of the material?

From the nature of the facial face of the fabric depend:

Appointment;

Exterior of the product;

Processing in the manufacture of the product

Properties of fabrics.

Girls, on the past lesson, we fulfilled with you to create models of clothing from various materials.

Question. When performing work, you encountered any difficulties?What questions arose?

In order not to make a mistake in choosing a fabric for the manufacture of any product, you must be able to correctly identify the properties with which they possess. Fabric properties affect the choice of model and product processing.

The main properties of tissues include mechanical, physical and technological.

  • Mechanical properties Determine how fabric belongs to the action of external forces.

Strength - The ability of the tissue to resist the rupture. This is one of the important properties affecting the quality of the fabric.

Crimprint - The ability of the tissue during compression and pressure to form folds.

Drapery - The ability of the fabric when it is hanging, descending with soft rounded folds. It is not by chance that the curtains and the curtains on the windows are called draperies.

Wear resistance- the ability of the tissue to withstand the action of friction, stretching, bending, compression, moisture, light, sun, temperature, sweat, etc.; Depends on the strength of the fibers of the fabric.

  • Physical properties - Properties aimed at preserving human health.

Heat shield properties- the ability of the tissue to keep warm human body; Depends on the composition, thickness and type of fabric finishing.

Gigroscopic - Fabric ability to absorb moisture.

Dust - The ability of the tissue to hold dust and other contaminants.

  • Technological properties - Properties appearing in the fabric in the process of manufacturing the product, ranging from the cutting and ending with the WTO.

Slip - It can occur when the fabrics are cut and the stratification and depends on the smoothness of the tissues and the type of their weave.

Syspability - It is that the threads are not held in open sections of the material and slip, they are trembling, forming a fringe.

Shrinkage - Reducing the size of the tissue under the action of heat and moisture depends on the composition of the fiber, structure and finishes.

Now, receiving new knowledge will continue the work on the creation of models of clothing.

The fabric that is removed from the machines is called harsh or harsh (Fig. 37). It has a rough surface. The color of the fabric corresponds to the color of the fibers, of which it is made (linen - grayish shade, cotton - yellowish).

Fig. 37. Sigar fabric: A - linen; B - Cotton

Sigor tissue is finished. The main purpose of the finish is to improve the quality and properties, giving the fabric of the commodity type.

The decoration consists of a number of various processes:

  • preliminary finish (cleaning and preparation of fabric);
  • whitening;
  • staining;
  • drawing pattern;
  • final finish.

Ready is called a fabric that passed the finish. Depending on the finish method get diverse species fabrics (Fig. 38).

Fig. 38. Types of fabrics by finishing method

The finished tissue has two sides - facial and involving (Fig. 39), the same width over the entire length of the tissue. There should be no spots and other flaws on the fabric. If there are defects on it (spots, non-crushed places, holes, pulled edge, etc.), then before starting work, they are denoted by chalk.

Fig. 39. The sides in the printed fabric: A - facial; B - invalid

The parties in the tissue are determined by the following features: drawing, gloss, pile, edge, finishing cleanliness (Fig. 40).
