Description

Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to a recycled viscose comfortable and environmentally friendly knitted fabric and a preparation method thereof. Background Art

[0002] Existing recycled fabrics are mainly recycled cotton and recycled chemical fibers, but these materials have many limitations in performance and application range, and it is difficult to meet the needs of modern consumers for high-quality and environmentally friendly products. Among them, recycled cotton fibers have poor spinnability, low strength, and many defects. These shortcomings greatly limit their application range. Recycled chemical fibers are mainly recycled polyester and recycled nylon. Although recycled chemical fibers have solved the problem of recycling waste materials to a certain extent, their biodegradability is poor and their impact on the environment is still large. Recycled chemical fibers are difficult to degrade in the natural environment, and long-term accumulation will cause soil and water pollution, which is not in line with modern environmental protection concepts. Recycled viscose fiber is a fiber produced by chemical spinning process based on plant raw materials (such as wood pulp, bamboo pulp, etc.). Compared with recycled cotton and recycled chemical fibers, recycled viscose fiber has a rich source of plant raw materials, strong renewability, and can be degraded faster in the natural environment, reducing pollution to the environment.

[0003] In summary, providing a knitted fabric made of a blend of recycled viscose fiber and ordinary viscose fiber can not only meet consumers' dual needs for comfortable sports and ecological environmental protection, but also effectively solve the problem of recycling waste fabrics. Summary of the invention

The pattern of the recycled viscose comfortable and environmentally friendly knitted fabric is a six-way cycle in a bottom-up order.

[0005] Among them, the organization structure of the first route is the lower needle cylinder floating thread organization, the lower needle cylinder tucking circle organization, the upper needle disk tucking circle organization, and the upper needle disk floating thread organization;

[0008] Among them, the organization structure of the fourth route is the lower needle cylinder floating thread organization, the lower needle cylinder floating thread organization, the upper needle disk circle organization, and the upper needle disk circle organization;

[0009] Among them, the organizational structure of the fifth route is the lower needle cylinder small circle organization, the lower needle cylinder small circle organization, the upper needle disk floating thread organization, and the upper needle disk floating thread organization;

[0010] Among them, the organizational structure of the sixth route is the lower needle cylinder circle organization, the upper needle cylinder circle organization, the upper needle disk floating thread organization, and the upper needle disk floating thread organization.

[0011] Furthermore, the first route and the second route use 75D / 24F recycled polyester low-elastic yarn.

[0012] Furthermore, the third route and the fifth route use 30D / 12F recycled polyester low-elastic yarn.

[0013] Furthermore, the fourth route and the sixth route use yarns made of 40S viscose fiber and combed cotton fiber through siro compact spinning.

[0014] Furthermore, in the yarn, the content of the viscose fiber is 20%-30%, and the content of the combed cotton fiber is 70%-80%.

[0015] Furthermore, in the viscose fiber, the content of the regenerated viscose fiber is 50%-60%, and the content of the ordinary viscose fiber is 50%-40%.

[0016] A method for preparing the above-mentioned recycled viscose comfortable and environmentally friendly knitted fabric comprises the following steps:
