Description

A kind of vinegar blue fiber functional knitted fabric and weaving method

technical field

The invention relates to the field of textiles, in particular to a functional knitted fabric of acetate green fiber and a weaving method.

Background technique

With the improvement of material living standards, people's requirements for daily necessities are constantly improving. At the same time, the requirements for textiles are no longer simply comfortable and beautiful; instead, textiles and clothing are required to be more fashionable and have more diversified performances. Along with the development of the national economy, the textile industry is also striving for reform and innovation. On the basis of the original textile industry, it overcomes the shortcomings of traditional textiles and creates new textiles with improved performance.

The fibers commonly used in the knitting industry have their own advantages, but also have their inevitable shortcomings. Acrylic fiber is one of the main varieties of synthetic fibers. Its texture is bulky, soft to the touch, low density, good thermal performance, and high resilience. It is known as artificial wool and is the best substitute for wool. Moreover, acrylic fibers have excellent light resistance, weather resistance, insect resistance, radiation resistance, microbial degradation resistance and good dyeability. But it is easy to generate static electricity and easy to fluff and pilling. The volume specific resistance of conventional acrylic fiber is 10 ¹³ -10 ¹⁴ Ω·cm, which is an insulating material. During post-processing, because of static electricity generated by friction, it is difficult to bundle and entangle with the workpiece. After being made into a finished product, it is easy to be stained and vacuumed, and when worn, people feel uncomfortable due to electric discharge. Therefore, it is basically only used in the field of wool spinning. This has just limited the development of acrylic fiber itself and acrylic fiber textiles. Common acrylic antistatic treatment generally adopts the method of applying antistatic agent on the surface during the production process. However, this method only obtains a temporary antistatic effect, and can only meet local processing needs. Its effect will be lost in wet heat treatment (including washing, dyeing and steaming), and the timeliness is shorter. Therefore, the development and production of permanent new functional acrylic fibers to meet the requirements of future textiles has become the development trend of China's modern textiles.

Contents of the invention

In order to solve the problems and deficiencies existing in the prior art, the present invention ensures that acrylic knitted products have excellent antistatic and anti-pilling properties, and provides a functional knitting fabric of acetate green fiber and a weaving method, so that the fabric is antistatic and anti-pilling.
