Problems solved by technology

However, due to the fine fiber, low strength, and poor fatigue resistance of rabbit hair, the blended fabric is not firm and the product is severely scratched. The same color effect can be achieved only by dyeing loose wool, which is directly unsuitable for the current low-volume, multi-color varieties. market demand

Abstract

The invention discloses a dyeing process of wool-rabbit hair blended yarns. The process comprises the steps of preparation, pre-treating, washing, dyeing, color-fixing, washing, finishing, quality inspecting, and packaging. According to the invention, the pre-treating step is added, such that dye uptake of the wool-rabbit hair blended yarns can be ensured under a relatively low temperature, and the strength of the yarns is not damaged. Therefore, economic benefit of the product can be improved. According to the invention, the dyeing process is simplified, product quality is ensured, and production cost is saved. Therefore, the process is suitable for industrialized productions.

Description

technical field [0001] The invention relates to a yarn dyeing method, in particular to a dyeing process of sheep and rabbit hair blended yarn. Background technique [0002] Rabbit hair and wool are precious natural protein fibers, which have been widely used in wool spinning products in recent years. They are blended with short down wool coats, which are elegant, smooth, good drapability, bright and natural luster, and good warmth retention. And other characteristics, and the price is moderate, favored by consumers. However, due to the fine fiber, low strength, and poor fatigue resistance of rabbit hair, the blended fabric is not firm and the product is severely scratched. The same color effect can be achieved only by dyeing loose wool, which is directly unsuitable for the current low-volume, multi-color varieties. market demand. . Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to overcome the deficiencies in the prior art a...
