Problems solved by technology

The cashmere content of fox velvet has a certain influence on the dyeing quality. The loose fibers of fox velvet contain a part of rough hair and gun hair that are difficult to color. The color and depth after dyeing are quite different from those of fox velvet. Under the premise of ensuring fiber quality, reduce the hair content of these miscellaneous hairs, and it is easy to cause the fluff to turn yellow or produce colored flowers

Abstract

The invention discloses a low-temperature dyeing process for a fox fleece. The process flow comprises soaping, washing with running water, dyeing, washing with running water, washing with ammonia water, washing with hot water, soaping, washing with hot water, fixing color, softening and drying. By adopting the low-temperature dyeing process, fox fleece fibers can be damaged little, the strength of single fibers can be kept to ensure smooth operation of a spinning procedure, and yarn faults can be reduced. The low-temperature dyed fox fleece fibers are soft, smooth and elastic, are good in moisture absorption, and can reserve original excellent performance, and especially can reserve original luster, style and handfeel after being made into knitted sweaters and underwear and improve the price and grade of products. The low-temperature dyeing process for the fox fleece is convenient in control of color difference from batch to batch, has energy-saving and emission-reducing effects and has good economic benefit and social benefit.

Description

[0001] technical field [0002] The invention belongs to a dyeing process, and in particular relates to a low-temperature dyeing process of fox velvet. [0003] Background technique [0004] Fox velvet is a high-grade textile raw material, which needs a reasonable dyeing and finishing process to ensure its good spinning performance. The cashmere content of fox velvet has a certain influence on the dyeing quality. The loose fibers of fox velvet contain a part of rough hair and gun hair that are difficult to color. The color and depth after dyeing are quite different from those of fox velvet. Under the premise of ensuring fiber quality, reduce the hair content of these miscellaneous hairs, and it is easy to cause the fluff to turn yellow or produce colored flowers. [0005] Contents of the invention [0006] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide a low-temperature dyeing process for fox velvet, ...
