Embodiment 1

[0042] A comfortable linen-like knitted fabric

[0043] Comfortable linen-like knitted fabric is made of blended acrylic staple, viscose fiber, cotton fiber and slub cotton; in comfortable linen-like knitted fabric, by mass percentage, acrylic staple is 15% and viscose is 35% , Slub cotton is 10%, and the balance is cotton fiber.

[0044] Include the following steps:

[0045] Step 1, surface modification of viscose fiber: prepare 1.0mol / L methyl methacrylate solution, adjust the pH to 6.0, then add the viscose soaked in 0.05mol / L potassium permanganate solution for 10min in advance The fiber is kept in a water bath at a temperature of 65°C for 120 minutes, and then the homopolymer is removed with a mixture of ethanol and water with a volume ratio of 4:1, and then dehydrated by centrifugation. After the product is air-dried, it is dried, which is surface modification. viscose, spare;

[0046] Step II, spinning: the surface modified viscose fiber obtained in step I is blended...

Abstract

The invention discloses a comfortable linen-like knitted fabric and a preparation process thereof. The comfortable linen-like knitted fabric is made of acrylic staple yarn, viscose fiber, cotton fiber and slub cotton blended fabric; the comfortable linen-like knitted fabric Among them, by mass percentage, acrylic staple fiber is 15% to 25%, viscose fiber is 25% to 35%, slub cotton is 10% to 20%, and the balance is cotton fiber. The comfortable hemp-like knitted fabric prepared by the present invention selects acrylic staple, viscose fiber, cotton fiber and slub cotton, and enhances its yarn-forming property with acrylic staple through surface modification of viscose fiber. There is better stability and compatibility between the thread and the second yarn, thereby improving the surface smoothness and hand feeling of the linen-like knitted fabric, and the shape is crisp and the texture is excellent.

Description

technical field [0001] The invention relates to the technical field of knitted fabrics, in particular to a comfortable linen-like knitted fabric and a preparation process thereof. Background technique [0002] With the strengthening of environmental protection awareness, people pay more attention to environmental protection, resource utilization and health and safety. Especially when choosing clothing, they have higher requirements for the environmental protection and health of clothing. [0003] The fabric made of natural hemp fiber has the characteristics of coolness and coolness, especially good moisture absorption and air permeability, excellent heat transfer and thermal conductivity. It has some disadvantages, such as itching, poor spinning cohesion, not easy to twist, more hairiness, and limited dyeing, poor elasticity, easy to wrinkle, poor wear resistance, etc. [0004] Cotton fiber has good hygroscopicity, moisture retention, heat resistance and hygienic properties...
