Problems solved by technology

With the development of knitting and non-manufacturing technology, because knitted fabrics can extend in all directions, have good extensibility, soft feel, good drapability, good elasticity, good moisture absorption, breathability and wrinkle resistance, etc., they are widely used in In various industries such as clothing fabrics and apparel, knitted fabrics are used more and more widely, and their market share far exceeds that of woven fabrics; however, knitted fabrics also have some defects caused by their own structure: easy to fall apart, snag, and easy to deform , especially after several times of washing, the dimensional stability is not good, and there are shortcomings such as curling
Woven fabric has the advantages of compact structure, stable size, not easy to snag, and good dyeability, but its extensibility, elasticity, moisture absorption and breathability are not as good as knitted fabrics

Embodiment 1

[0020] combine figure 1 , in this embodiment, 105dtex / 36F sheath-core type hot-melt polyester yarn is used as the bonding fiber, and its surface melting point is 170°C; 17.8tex cotton yarn is used as the main yarn raw material (strength and elasticity are the bonding fiber of the technical solution of the present invention) It has little influence on the raw material of the main yarn, so it is omitted in this embodiment). Steam the raw material of the main yarn first, and control the temperature of the steamed yarn at 95°C. After 30 minutes of treatment, cool the raw material of the main yarn to room temperature. Weaving is carried out on the machine, and the bonding fiber is interwoven with the main yarn raw material, among which, the combined figure 2 , the adding method of bonding fiber is: using bonding fiber, that is, sheath-core hot-melt polyester yarn as the ground yarn, the amount of bonding fiber added is 15%, 17.8tex cotton yarn as the veil, 58tex cotton yarn as th...

Embodiment 2

[0024]The settings and principle of this embodiment are the same as those of Embodiment 1, the difference is that in this embodiment, 70dtex / 24F sheath-core type hot-melt polyester filament is used as the bonding fiber, and its surface melting point is 170°C; colored polyester filament is used as the bonding fiber. The raw material of the main yarn has a denier of 200dtex. Weaving is carried out on a 34-inch, 22 needles / inch, 72-way double-sided jacquard circular machine, and the bonding fibers are in the form of plating (filling yarn is a kind of pattern organization of knitted fabrics, and all coils or some of its coils are made of two Composed of one or more yarns, the plaiting organization can be divided into weft knitting and warp knitting, single-sided and double-sided, plain color and pattern) and the main yarn raw material is interwoven, and the amount of binder fiber added is 25%. The weaving method adopts two-color double-sided incomplete jacquard (among them, accord...

Abstract

The invention relates to a processing process of stable-dimension knitted fabrics, and belongs to the technical field of knitted fabric processing processes. The processing process comprises the steps of material selection, yarn steaming, knitting and afterfinish. Yarns with good elasticity, high intensity and low shrinkage rate are selected; the structure parameters of loops are determined so that the structure parameters are identical to the structure parameters in the full loosening state, a proper on-machine process is selected, the yarns adopts an interweaving mode for knitting the texture structures for effectively improving the dimension stability of the knitted fabrics; and a tensile force reduction and forced contraction mode is adopted for realizing the afterfinish on the fabrics, the surface layers of bonding fiber is molten, and molten nodes are formed inside the fabrics for improving the fabric dimension stability. The technical scheme is adopted, and the processing process has the advantages that the fabric dimension stability is good, the production process is green and environment-friendly, and the like.

Description

technical field [0001] The invention relates to a processing technology of dimensionally stable knitted fabric, which belongs to the technical field of knitted fabric processing technology. Background technique [0002] Textile fabrics are mainly knitted fabrics, woven fabrics and non-woven fabrics. Knitted fabrics and machine-made fabrics are made by weaving technology, while non-woven fabrics are processed by fiber bonding and fusion. With the development of knitting and non-manufacturing technology, because knitted fabrics can extend in all directions, have good extensibility, soft feel, good drapability, good elasticity, good moisture absorption, breathability and wrinkle resistance, etc., they are widely used in In various industries such as clothing fabrics and apparel, knitted fabrics are used more and more widely, and their market share far exceeds that of woven fabrics; however, knitted fabrics also have some defects caused by their own structure: easy to fall apart...
