Problems solved by technology

Vegetable dyes are non-toxic and environmentally friendly, and are highly compatible with the product performance of regenerated fibers. Using plant dyes to dye regenerated nylon fibers can improve the added value of products while ensuring the performance of yarns, endowing nylon fiber yarns with green, sustainable, and Renewable product features, there is no special dyeing process for recycled nylon yarn in the prior art, therefore, it is necessary to design an environmentally friendly dyeing process for recycled nylon yarn

Description

An environmentally friendly dyeing process of recycled nylon yarn technical field The invention belongs to technical field of yarn, relate to a kind of environment-friendly dyeing process, particularly a kind of regenerated nylon yarn Eco-friendly dyeing process. Background technique [0002] Environmental protection is not only the theme of the development of the times, but also the future development direction of the textile industry. The meaning of textiles has changed from Repel the cold and keep warm, and expand to beauty, fashion, health, environmental protection and other aspects. Recycled nylon yarn is to use chemical recycling and regeneration technology to recycle the discarded nylon fabric, and then pass through chemical recycling. It is decomposed into nylon raw materials by chemical treatment, and then spun into regenerated nylon yarns. Plant dyes are non-toxic and environmentally friendly. It is in line with the product performance of regenerated fibe...
