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

Abstract

The invention provides an environment-friendly dyeing process of regenerated nylon yarns. The environment-friendly dyeing process comprises the following steps: treating cheese yarns through a padding type yarn treating machine, and specifically comprises the following steps: loading a shaft, padding a working solution, oxidizing and curing, washing with water, drying and unloading a bobbin from the shaft.

Description

technical field [0001] The invention belongs to the technical field of yarns, and relates to an environment-friendly dyeing process, in particular to an environment-friendly dyeing process of regenerated nylon yarn. 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 significance of textiles has expanded from cold protection to warmth, to beauty, fashion, health, environmental protection and other aspects. [0003] Regenerated nylon yarn uses chemical recycling and regeneration technology to recycle waste nylon fabrics, and then chemically decomposes them into nylon raw materials, which are then spun to make recycled nylon yarns. 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 prod...
