Functional gradient layer knitted fabric and preparation method thereof

Abstract

The invention discloses a functional gradient layer knitted fabric and a preparation method thereof. A surface layer of the functional gradient layer knitted fabric is obtained by waving chemical fiber filaments. A middle layer and an inner layer of the knitted fabric are obtained by waving blended yarns. The blended yarns are blended yarns of hemp fibers, cotton fibers and chemical fibers. In theblended yarns, the mass ratio of the hemp fibers, the cotton fibers and the chemical fibers can be 30-50:40-30:30-20. The chemical fibers are at least one of polyester, nylon, spandex, viscose fibersand modal fibers. The quality percentage of the hemp fibers is 30 percent to 50 percent. The chemical fiber filaments is covered on the surface layer of a hemp knitted fabric of the functional gradient layer knitted fabric and the preparation method thereof, which increases the strength of the fabric, improves the quick drying and air permeability of the fabric, and improves the anti-fuzzing andpilling performance of the fabric. The inner layer of the hemp knitted fabric closes to skin with cotton yarns, enhances the sweat absorption, dry and wholesomeness of the fabric, and quickly guides water away after absorbing water.

Description

technical field [0001] The invention relates to a textile fabric and a preparation method thereof, in particular to a functional gradient layer knitted fabric and a preparation method thereof. Background technique [0002] Knitted fabrics have soft texture, moisture absorption and breathability, excellent elasticity and extensibility and manufacturability. Knitted clothing is comfortable to wear, close to the body, without a sense of tightness, and can fully reflect the curves of the human body. Modern knitted fabrics are more colorful and have entered the stage of multi-functional and high-end development. New knitted fabrics with various texture effects and different functions have been developed, bringing unprecedented sensory and visual effects to knitted fabrics. [0003] The invention patent application of "a hemp knitted fabric" with application number 200910078967.0 discloses a hemp knitted fabric, including a preparation method of hemp blended yarn.

AI Technical Summary

Problems solved by technology

[0006] Hemp fiber has high bending and torsional rigidity, poor length uniformity, more short fibers, high short-lint content, low cohesion, poor spinnability, and the fiber end is easy to pop out of the yarn body, with many hairiness, hard and long, and cannot be spun high Counted yarn; pure hemp yarn is hard, brittle and straight, and has defects such as low single strength and many knots, resulting in difficulty in bending and looping, and many broken yarns and defects during weaving. The drapability is poor; there are impurities such as hemp skin, parallel silk and hard strips
