Abstract

This method for producing synthetic fabric with a "wet silk" effect on the surface is used in the production and finishing of synthetic fabrics, produced from polyamide or polyester yarns through huckaback weaving. The aim of this method is to produce soft fabric with a "wet silk" effect on the surface. With this method, the fabric weft made of polythreaded extruded or textured polyamide or polyester yarns, with linear density of elementary threads ranging from 0.1 to 0.17 tex, the fabric is washed, fixated, polished with polishing rollers, which rotate at 200-500 min<-1>, the fabric must be transported through these rollers at a speed of 3-5 m/min, the coarse size of abrasive particles must range from No. 5 to 10. After that, the fabric is painted, dried and processed by water and dirt repelling measures.

Description

The present invention relates to a method for producing synthetic fabrics with a wet silk surface using polyamide or polyester yarns in the warp and weft.

A known method of producing a fabric with a pulled surface (see Russian Patent No. 2040613, D06C 29 / 00,29.03.93), wherein the fabric is woven from polyamide yarns, is thermally fixed, washed, dried, calendered and then dyed together. This produces a fabric with a pulled surface and improved performance.

Known Method for Making Textile Fabric with Gauze Leather (See SU # 1416561.D06C 29/00, 20.09.83), in which the fabric is woven from synthetic plain or textured yarn into which needle-punched bicomponent yarns or split fibers are woven , which forms a short fluff on the surface of the fabric to form the image of a genuine leather.

The closest to the proposed method is a method of making synthetic fabric from polyamide yarns (see Specifications 2R 95 OWL), where the fabric is woven from polyamide yarns using 15.6 tex in weft and 6.7 tex in weft, 5-0.65 tex.The woven fabric is dyed, creased and treated to provide water repellent properties.

Known techniques do not provide the fabric with sufficient softness, the needle pile forming method is quite complex and does not produce a wet silk effect on the fabric surface.

The object of the invention is to improve the performance and organoleptic properties of the fabric and to obtain a wet silk surface.

This object is achieved by the fact that in a known method of producing textile fabric, in which the fabric is woven with polyamide yarns, dyed and specially processed, the fabric is woven from polyester or polyamide multi-ply pneumotextured or textured yarns with a linear density of 0.1-0, 17 tex, then wipes, fixes, polishes the fabric by passing through grinding shafts rotating at 200-500 min ' ¹ at a velocity of 3-5 m / min, coarse abrasive

No. 5-10, followed by dyeing, drying and treatment with water and dirt repellents.

The following examples illustrate the method:

Example (prototype)

The fabric is woven from polyamide yarn by linen weave using 6.7 tex for warp and 15.6 tex for weft with a linear density of 0.56-0.65 te for the basic filament. The woven fabric is dyed in the ejector by acid dyeing at 90 ° C to 100 ° C, creasing at 120 ° C, and then treated with water repellents.

Sets the softness of the tissue organoleptically and uses a 5-point scale for clarity. It uses a three-point scale (intense, medium and slight) to determine the effect of wet silk.

An example

The fabric is weaved using weft polyamide threads of 7.2 tex with a linear density of 0.42 tex for weft - polyamide multifilament pneumotextured yarns of 20 tex with a linear density of 0.14 tex in the weft. 80 ° C and fix at 180 ° C, then sand down the right side of the fabric, passing through the grinding machine MH-1800 table. The abrasive cloth is dyed in the ejector with acid dyes at 90 ° C to 100 ° C, dried at 140 ° C and treated with water repellents. Sets the effect of soft and wet silk as 1 example.

An example

The fabric is woven using weft polyester yarns for 7.6 tex, and for linear yarns, 0.31 tex. For weft, polyester multifilament pneumotextured yarns for 20 tex, with the filament liner density listed in the table, washed as in Fig. 2, then fixed at 190 ° C. grinds with the parameters given in the table and paints with dispersion paints at 110130 ° C.

An example

The fabric is woven from polyamide yarns of 7.2 tex. Elementary Filament Linear Density 0.42 tex. For weft use polyamide multifilament textured yarns of 18 tex, with elementary filament linear densities indicated in the table.

An example

The fabric is woven as 3 e.g. weaves polyester multifilament textured yarns for weaving 18 tex with a linear density of elementary filaments given in the table, further processed and studied as 3 weft.

An example

The fabric used for warping is 7.6 tex, weft 20 tex polyester multifilament pneumotextured yarns with a linear density of 0.11 to 0.14 tex respectively.

An example

The fabric weaves for warp use 7.2 tex. - for weft 18 tex. polyamide multifilament textured yarns with a linear density of 0.11-0.14, respectively, of elementary filaments, are further processed and investigated as e.g.

An example

The fabric is woven from polyamide or polyester yarns as a prototype, processed and examined as 2 and 3 e.g.

The qualitative properties of the treated fabric are shown in the table, which shows that the fabric obtained in the claimed manner is considerably softer than the known fabric, producing a short fluff on the fabric surface during the sanding process, giving the fabric a wet silk surface effect.

The essential distinguishing feature of the claimed process is that polyamide or polyester multifilament pneumotextured or textured yarns are used for the weaving of the silk surface, with a linear density of the filaments in the specified sequence, and the surface treatment of the fabric is performed within the specified parameters.

The declared mode parameters are optimal. As can be seen from the table, using polyamide or polyester yarns with low elementary filaments with a linear density of 0.5-0.65 tex (prototype), the fabric is hard and even when sanded it does not produce a wet silk surface (eg 8) since the thread of such a fabric has a small amount of elementary filaments that are sufficiently hard and difficult to break. When sanded, a small number of these filaments are disrupted, the individual lumps are obtained on the surface, and the wet silk surface with a uniform, even and short lint is not obtained. The use of multi-stranded pneumotextured or textured yarns with a linear density of 0.1-0.17 for elementary filaments results in a high-quality wet silk surface because thin and flexible filaments are easily disintegrated during grinding and evenly cover the surface of the fabric in the form of a short dense pile. softness of the material. The use of yarns with a linear density of less than 0.1 tex (see Example 3b, 5b) is impractical because the processing becomes more complex by obtaining a fabric surface of the same quality and when the linear density is greater than 0.17 tex. , (see 3d, 5c), they are more difficult to break, while the fabric is harder and the effect of wet silk on the fabric surface is reduced.

From Ex. 6 and Ex. It can be seen that weaving of polyester or polyamide yarn for weft and weft use of multi-strand textured or pneumotextured yarns produces a soft fabric with a high quality (intense) wet silk surface, but in this case increases the cost of the fabric. Examples 3 and 5 indicates that the intense wet silk surface and sufficient softness of the fabric are obtained by weaving the fabric with multi-strand textured or pneumotextured yarns.

The grinding parameters are optimal. Passing fabric through grinding shafts at speeds of less than 3 m / min (see example 2d) results in reduced productivity with similar fabric quality, and increasing the speed of movement of the fabric above 5 m / min (see example 4d) reduces the wet surface of the fabric intensity.

Reducing the spindle revolutions of the grinding shafts to less than 200 min ' ¹ results in poor quality silk surface due to too long fibers on the fabric surface (see example 5d), which can subsequently peel. At a shaft spacing greater than 500 min ' ^{1, the} strand structure is disrupted and the fabric ruptures (see Example 4c).

Abrasive roughness is also optimal. Abrasion less than 5 is ineffective (see Example 2e) because the lint is not raised and the abrasion itself wears off quickly. Increasing the coarseness of the abrasive by more than 10 (see Example 3e) tears off the long hair and results in an uneven surface of the lint.

Thus, the proposed method provides a high quality wet silk surface and increases the fabric softness by a factor of 3, which allows us to expand the range of products made from this fabric.
