Abstract

The method for producing the textile material with a flocculent multicolour (m'lange) surface is used for finishing textile products. This method aims to reduce the input of energy, improve organoleptic and exploitation attributes, receive intense and even m'lange on the surface of the fabric. For that purpose, the fabric is knitted out of extruded yarns, which consist of a polyester and a fibre viscose, the ratio being 1:1, the knitted material is sanded from both sides in a sanding unit, painted by a direct paint (for the colouring of the viscose fibre) and then fixated.

Description

FIELD OF THE INVENTION The present invention relates to the finishing of textile products, more particularly to a process for obtaining materials with a soft mottled color.

Known method of producing a material having a pile surface (see French Patent No. 263652, DO6C 23/00, 16.03.1990), wherein a fabric having a mesh structure is deposited on a textile backing which is capable of forming a fluff. liftable.

Also known is a method of obtaining a soft surface textile material (cf. German Patent No. 2885III, D06C 23 / Ι, Ι99Ι · Ο4.Ο4), in which the material from a mixture of cotton and polystyrene, after being dried, is crumpled in a special machine until creasing, then, after the convexity of the fabric, it is sewn.

Known techniques do not provide the material with sufficient softness, patchwork is not uniform, and spit fluff wears quickly, which degrades the material's performance.

The closest to the proposed process is to obtain a textile fluffy material (see Japanese Application No. 63-23309,

Θ9θθ.05oI5), in which the weft is composed of a non-shrinking complex yarn of between 5 and 35 tex and a weft of two types of fiber having a coefficient of shrinkage of between 5% and 40% and a thickness of 0,08 tex. , paints and then brooms.

The material obtained in a known manner is not soft enough, the pile-like fluff is rapidly worn, which reduces the material performance, the melange is insignificant, and the high energy consumption of the pre-heat treatment of the material.

The object of the invention is to reduce energy consumption, to improve the performance and organoleptic properties of the material, to obtain a uniform and intense pattern (melange) on the surface of the material.

This object is achieved by knitting, in a known method of producing a textile fabric with a pile surface, which is made of a fiber comprising a down, heat treatment, washing, dyeing and combing, of a pneumote-textured yarn composed of polyester and viscose fibers in a ratio of 1: 1, polishes the knitted fabric, dyes the viscose fiber with dye and fixes.

The following examples illustrate the method.

Example I.

The material is knitted from pneumotextured 23-25 tex. Polyester and viscose, having a ratio of III yarn, to Class 16-20 circular knitting machines, interlacing or plain weaving. In the first case, the material produces a reciprocal fluff, in the second, the material is less than a square meter. The knitted material is sanded on a MH-I800 sanding machine at a speed of 6 m / min. Sand the right side 2 times, the bad side once. Polish the paint in the bath with direct paint90-I00 ° C, rinse and wash in the sleeve ”min. 60 ° C and 15 min. 65 ° C. The material is then dried in a drying machine and fixed at 18 ° C.

The softness effect of the material is determined organoleptically, but for the sake of clarity it uses a 5-point scale. The degree of peeling is determined visually after 5 washes, and the degree of peeling is determined by a three-point scale (intensive, medium and slight).

Example 2.

The fabric is knit as in Fig. 1 from pneumotextured yarns, only with different polyester to viscose ratios (I: I, 2 «I). The knitted fabric is polished and treated as in Fig. 1. The effects of softness, variegation and peeling are determined analogously to Fig. I

Example 3.

Knit the material as in fig. I of pneumotextured yarns only with different polyester to viscose ratios (1: 1,1: 2 to 2: 1). The knitted material is dyed, rinsed, dried and fixed as in Fig. 1, then sanded on both sides by a sander. Softness, mottling and peeling effects are set analogously to Fig. L

Example 4 °

The material is woven in a known manner (see <'Japanese Application No.

63-23309). It uses almost non-shrinkable / bony) weft yarns of 23 textiles for warp and two types of weft yarns of polyester and polyamide with a shrinkage factor of 5-40%. «The woven fabric is heat-treated to produce loops on the surface of the fabric. it washes the material. and paints in an ejector dyeing machine with acid paint at 95 ° C. Passes dried material through a spinner at 13 m / min. The material so treated is investigated as in Figure 1,

Example 5 ·

The material is knit as in Fig. I of pneumotextured yarns with different polyester to viscose ratios (1: 1.1: 2.2: 1), sanded, knitted in the bath at a dispersion temperature of 90-100 ° C, rinsed, dried, fixed and examined as .

Example 6.

The material is knit as in Fig. 1 from pneumotextured yarns with different polyester to viscose ratios (I: I, 1: 2.2: I). The knitted material is dyed with dispersion dyes as in fig. 5, washes, dries and fixes as in Fig. I, then polishes and examines as in Fig. L.

The qualitative properties of the treated material are given in the table, which shows that the material obtained in the claimed manner is considerably softer, more peel-resistant and intense melancholy than the known. In a series of processing operations, the pneumote-textured filament twist ratio and fiber ratio of 1: 1 are optimal for obtaining quality material with a specific pile structure. Increasing the viscose content by more than 50% decreases the melange effect by dyeing a larger proportion of the viscose fiber, and using a higher viscose content results in a higher down, which is undesirable as it increases the material's degree of adhesion (see Fig. 3 »3 *» 5 ' , 6 ').

Increasing the polyester fiber content by more than 50% reduces the melange effect as this fiber is less dyed and harder to extract (see Fig. 2 ', 3 "» 5 "» 6 ").

The essential distinguishing feature of the claimed method is that the material is obtained by grinding rather than by grinding.

For sanding the surface of the material, there are only tapered polyester and viscose fiber tips that cover the entire surface of the material in the form of a short, dense pile, resembling woolen fabric surfaces. This fluff is particularly resistant to peeling even after repeated washing.

By feeding the material, as is known in the art, the fluff is pulled from the inside of the fiber to the surface, resulting in a much longer and rarer tuft-like structure which increases the peeling of the material when worn.

Contrary to the known method, the material is first sanded and then dyed.Dyeing with a formed pile surface gives a smooth and intense melange, as the split top fiber in the form of lint absorbs the dye better and more evenly (see Fig. 1,2). , 5) In addition, during dyeing, the fluff sticks to the base of the fabric, shortens and distributes evenly in all directions, which not only enhances the mild effect but also the peeling resistance of the fluff.

When grinding a colored material, marl effect is negligible (see _figure. 3.3, 6.6 ', 6') for _p is lifted only a part of the painted fiber fluff is formed in one direction only to stain and nenusidažiusio lint fibers overlap one another, which results in substantial reduces the melancholy effect, in addition, the fluff gets longer and tends to peel more _o

The most intense melange effect is obtained using direct dyes that viscose the viscose fiber (see Fig. 1,3,5)

As can be seen from the table, the proposed method increases the material's peeling resistance, the material's intense melange (mottling) and the soft surface by 3 times. In addition, the proposed method reduces the amount of energy used in the prior art to pretreat the material.
