Description

Technical Field

[0001] This invention relates to the field of textile technology, and in particular to a recycled viscose comfortable and environmentally friendly knitted fabric and its preparation method. Background Technology

[0002] Existing recycled fabrics are mainly composed of recycled cotton and recycled chemical fibers. However, these materials have many limitations in terms of performance and application range, making it difficult to meet the demands of modern consumers for high-quality and environmentally friendly products. Among them, recycled cotton fibers have poor spinnability, low strength, and many defects, which greatly limit their application range. Recycled chemical fibers are mainly composed of recycled polyester and recycled nylon. Although recycled chemical fibers have solved the problem of recycling waste materials to some extent, their poor biodegradability still has a significant impact on the environment. Recycled chemical fibers are difficult to degrade in the natural environment, and long-term accumulation will cause soil and water pollution, which is inconsistent with modern environmental protection concepts. Recycled viscose fiber is a fiber produced by chemical spinning process based on plant-based raw materials (such as wood pulp, bamboo pulp, etc.). Compared with recycled cotton and recycled chemical fibers, recycled viscose fiber has abundant plant-based raw material sources, strong renewability, and can degrade quickly in the natural environment, reducing environmental pollution.

[0003] In summary, this invention provides a knitted fabric made from a blend of recycled viscose fiber and ordinary viscose fiber, which not only meets consumers' dual needs for comfortable movement and environmental protection, but also effectively solves the problem of recycling waste fabrics.

[0020] Step 4: The fabric is subjected to pretreatment, dyeing, drying and setting in sequence to obtain the recycled viscose comfortable and environmentally friendly knitted fabric.

[0021] Furthermore, the dyeing auxiliaries include: sodium sulfate 5g / L-10g / L, anti-wrinkle agent 2g / L-10g / L, chelating dispersant 3g / L-10g / L, soda ash 0.1g / L-5g / L, and leveling agent 1g / L-5g / L.
