Comfortable wrinkle-resistant fabric and preparation method thereof

Abstract

The invention provides a comfortable wrinkle-resistant fabric, which is prepared by weaving high-twist wrap yarns, wherein the high-twist wrap yarns are wrapped by leather yarns and core yarns; the core yarns are comfortable short fibers; the leather yarns are chemical fiber filaments; the weight ratio of the chemical fiber filaments to the comfortable short fibers is 10-80:20-90; the leather yarns are wrapped on the core yarns in spiral wrapping mode; the degree of twist of the chemical fiber filaments and the comfortable short fibers in the Z-direction or S-direction is 1 to 25T / cm; the chemical fiber filaments are made of terylene, chinlon, polypropylene, PTT, silk, or terylene FDY; and the comfortable short fibers are one or more fibers in pure cotton, viscose, fur, flax, bamboo fiber, corn fiber, soybean fiber and milk fiber. The comfortable wrinkle-resistant fabric has the advantages of high wrinkle resistance, moisture absorption, wear resistance, pilling resistance, sense of flax, air permeability and machine-wash property, comfortable wear, high strength and quick drying of absorbed moisture, and is an ideal comfortable wrinkle-resistant shell fabric.

Description

technical field [0001] The invention relates to a comfortable anti-wrinkle fabric and a manufacturing method thereof. The comfortable anti-wrinkle fabric is woven from a strong-twisted wrapping yarn, and the strong-twist wrapping yarn is wrapped by a core yarn and a sheath yarn; The core yarn is a comfortable staple fiber, and the cover yarn is a chemical fiber filament; the cover yarn is wrapped on the core yarn in a helical winding manner. Background technique [0002] Among the existing clothing materials, natural fibers such as cotton, wool, silk, and hemp, artificial fibers such as viscose fiber, bamboo fiber, etc. have good hygroscopic performance, but poor wrinkle resistance; chemical fibers such as polyester, nylon, polypropylene, etc. have wrinkle resistance. Good, but poor hygroscopicity, uncomfortable for people to wear, people have been making difficult choices on wrinkle resistance and comfort. In the history of anti-wrinkle fabrics and anti-wrinkle comfortable...

Problems solved by technology

However, this kind of finishing agent is easy to release formaldehyde in the process of fabric finishing and wearing, causing environmental pollution and harm to human health.

In order to solve this problem, a series of low-formaldehyde cross-linking agents, ultra-low-formaldehyde cross-linking agents and even formaldehyde-free finishing agents such as polybasic acid finishing agents were developed at home and abroad. Accompanied by the defects of poor washing fastness and yellowing of fabrics, among them, the effect of multi-acids and BTCA is better, but the price is expensive, which affects its popularization and application

[0006] The anti-wrinkle finishing of pure cotton improves some anti-wrinkle properties of pure cotton fabrics, but the anti-wrinkle effect is not ideal, and has the following defects that cannot be improved:

[0007] 1. The cross-linking of the finishing agent changes the mechanical structure of the cotton fiber and the fabric and concentrates the stress. Therefore, after the fabric is finished, the strength of the fabric will drop significantly, and the drop can reach 20% to 30%, which will seriously affect The performance and service life of the fabric;

[0008] 2. Because of the post-finishing method, the combination fastness between the anti-wrinkle finishing agent and the fabric is poor, so the anti-wrinkle effect is poor in washing resistance. After 20 to 30 times of washing, the anti-wrinkle effect of the fabric decreases significantly;

[0009] 3. Among the anti-wrinkle finishing agents, the finishing effect is the best. The most mature technology is 2D resin finishing, which is also the mainstream product of pure cotton anti-wrinkle finishing. Because it is a formaldehyde condensation product, there will be free formaldehyde in fabric finishing and use. released, causing pollution to the environment and harm to the human body;

The silk skeleton of the wrinkle-resistant pearl fiber yarn produced by this method is polyester filament, and the fiber pearl fiber with poor wrinkle resistance is wrapped on the outside of polyester filament, which affects the wrinkle resistance of polyester filament; therefore, this method produces The effect of anti-wrinkle pearl fiber yarn is not obvious
