Description

Technical Field

[0001] The invention relates to the technical field of knitted fabric processing, in particular to a preparation process of nylon and polyester stretch knitted fabrics. Background Art

[0002] Knitted fabric is a fabric formed by bending yarn into loops and interlacing them with knitting needles. The difference between knitted fabric and woven fabric is that the yarn has a different form in the fabric. Knitting is divided into weft knitting and warp knitting. Knitted fabric is widely used in clothing fabrics and linings, home textiles and other products, and is loved by consumers. Compared with cotton knitted fabrics, nylon and polyester knitted fabrics have better elasticity and are widely used in the clothing industry.

[0003] Since polyester and nylon materials are easy to deform, knitted fabrics made of polyester and nylon materials need to be heat-pressed and shaped after they are knitted. In the prior art, traditional heat-pressing and shaping methods all use equipment such as heat-pressing and shaping machines. However, since fluff or dust may remain on the surface of the fabric during the knitting process, in order to prevent dust or fluff from adhering to the fabric during heat pressing, it is usually necessary to clean the fabric. Most traditional heat-pressing and shaping machines do not have the function of cleaning the fabric. Therefore, before the fabric is heat-pressed, the fabric needs to be cleaned manually. This method is very inconvenient and increases the number of fabric processing steps, seriously affecting work efficiency. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and a preparation process of nylon and polyester stretch knitted fabrics is proposed.
