Embodiment Construction

[0028] A yak wool dyeing method using yak wool anti-felting pretreatment according to the present invention will be further described in detail through specific examples below.

[0029] A method for dyeing yak cashmere by anti-felting pretreatment, comprising the steps of:

[0030] (1) Anti-felting pretreatment process

[0031] Pretreatment: place the yak wool in a solvent with a mass fraction of 1% alkyl polyoxyethylene ether (that is, Pingpingjiao), heat wash it for 20-40mim at an ambient temperature of 45°C, and finally wash it with ethanol and hot water to remove it. Fiber residual impurities;

[0032] Oxidation treatment of fibers: at room temperature, prepare a mixed solution of hydrogen peroxide and sodium pyrophosphate, and place the fibers in the mixed solution to react;

[0033] Oxidation treatment process conditions: the treatment bath is a solution containing 6% hydrogen peroxide with a mass concentration of 30%, sodium pyrophosphate 1-2g / L, pH 4.0, normal temper...

Abstract

The invention relates to a yak wool dyeing method for anti-felting pretreatment of yak wool; the method comprises: (1) performing anti-felting pretreatment, to be specific, oxidizing fiber, reducing the fiber, treating the fiber with proteinase, inactivating the proteinase, and washing; (2) dyeing, to be specific, dyeing with active dye at low temperature. The method has the advantages that the original single dyeing technique is replaced with the anti-felting pretreatment dyeing technique, and dyeing is benefited; in addition, the anti-felting treatment based on original staining enables the flake layer of the yak wool to be further opened, the ability of dye molecules to diffuse in the region is enhanced, dyeing activity of yak wool fiber is improved, and low-temperature dyeing of the yak wool is achieved.

Description

【Technical field】 [0001] The invention belongs to the technical field of yak cashmere fiber processing, and in particular relates to a yak cashmere dyeing method using yak cashmere anti-felting pretreatment. 【Background technique】 [0002] Most of the hair fibers of yak hair are composed of scale layer and cortex layer, and only contain a very small number of medulla layer. The shape of the scales of different wool fibers varies with the type of wool fiber. The surface shape of the scales of yak wool fibers is ring-shaped, and the fine hair scales are covered on the hair shaft, similar to cashmere, and the scale edges are not obvious; the scales of semi-fine hair Fish scales or tiles cover the hair shaft; the scales of coarse hairs are corrugated or compound tiles, the thicker the hairs, the more blurred the structure of the scales, and the less visible. During dyeing, the dye is not easy to enter the cortex layer, and the dyeing effect is poor, resulting in a single color ...
