Problems solved by technology

However, the respective characteristics of ramie and viscose fibers bring certain difficulties to the dyeing and finishing process. If they are not handled properly, there are also disadvantages such as rough hand feeling, easy to wrinkle, poor elasticity, itchy feeling when worn next to the skin, and large shrinkage rate.
Because ramie viscose fabrics after general dyeing and finishing treatment tend to feel hard, have poor elasticity and ductility, and have monotonous styles, people will feel tight and stretchy when wearing clothes made of this fabric.
Therefore, traditional ramie viscose fabrics can no longer meet the needs of the market, and vigorously developing high-quality products is a key issue that ramie viscose fabrics and even garment manufacturers are facing at present.

Abstract

The invention discloses a ramie and viscose interwoven fabric. The fabric is obtained by blending and interweaving ramie fibers and viscose fibers and then performing pretreatment, dyeing and after-treatment. The weight percentage occupied by the ramie fibers in the fabric is 55-75 percent, and the weight percentage occupied by the viscose fibers in the fabric is 25-45 percent; the pretreatment comprises cold-batch, desizing and oxygen bleaching; the dyeing adopts wet short steaming, pad-dyeing and dyeing processes of vat dyes; the after-treatment includes soft finishing, drying and setting. In addition, in the invention, the ramie and viscose interwoven fabric has the advantages of being uniform in dyeing, high in color fastness, rich in color and luster, soft in hand feeling and close in texture.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a ramie viscose interwoven fabric. Background technique [0002] As we all know, the main component of ramie is cellulose fiber. Natural ramie fiber contains impurities such as pectin, lignin, wax and ash, so it has high breaking strength, high wet strength and low breaking elongation. Therefore, the pretreatment of fabrics made of ramie is difficult and demanding. Viscose fiber is made of natural cellulose and processed by certain chemical methods. Ordinary viscose fiber has poor wet strength, low breaking strength and high breaking elongation; its cortex structure has a great influence on dyeing, and its alkali resistance is low. [0003] A new type of fabric can be obtained by blending ramie and viscose fibers, which can have the advantages of rough, solid, crisp, elegant, light, cool, breathable, antibacterial, and health care that ramie and viscose fabrics have. However,...
