Problems solved by technology

However, the respective characteristics of flax, viscose and spandex 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 linen viscose elastic fabrics that have undergone general dyeing and finishing treatment tend to have a hard hand, poor elasticity and ductility, and monotonous styles, people will feel tight and stretchy when wearing clothes made of this fabric.
Therefore, the traditional linen viscose elastic fabric can no longer meet the needs of the market, and vigorously developing high-quality products is the key problem faced by linen viscose elastic fabric and even garment manufacturers.

Abstract

The invention discloses a flax and viscose elastic fabric. The fabric is formed by blending and weaving flax and viscose blended yarn and spandex stretch yarn and then carrying out pretreatment, dyeing, soft finishing, and drying and shaping. The content of the spandex stretch yarn in the fabric ranges from 3 wt% to 10 wt%. Bio-enzymes are adopted for pretreatment for cold stacking and oxygen bleaching processes. A wet short steaming pad dyeing process of reduced dye is adopted for dyeing. Two times of softening are adopted for soft finishing. An FIR4 drying and shaping machine is adopted for drying and shaping. In addition, the flax and viscose elastic fabric has the advantages of being uniform in dyeing, high in color fastness, full in color, soft in hand feeling, compact in texture and rich in elasticity.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a linen viscose elastic fabric. Background technique [0002] As we all know, flax belongs to bast fiber, the main component is cellulose fiber. Natural flax fiber contains impurities such as pectin, lignin, wax and ash, generally as high as 20%, its molecular polymerization degree is above 10,000, and its crystallinity reaches 70%. The flax fiber has high breaking strength, high wet strength and low breaking elongation. Therefore, the pretreatment of fabrics made of flax 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 elastic fabric can be obtained by blending linen viscose blended yarn and spandex elasti...
