Abstract

The invention belongs to the technical field of fiber dyeing, and in particular relates to a dip-dyeing process for rabbit down fibers with low short-down breakage rate. The process includes the following steps: pre-treatment: wash the rabbit down fiber in the cleaning solution; dyeing, post-treatment, dehydration, and drying; the cleaning solution includes the following components: fatty alcohol polyoxyethylene ether 0.5-3g / L, alkylphenol polyoxyethylene ether 0.1‑0.5g / L, alkyl glucoside 1‑5g / L, tetraacetylethylenediamine 0.05‑0.5g / L, baking soda 0.5‑2g / L, water as solvent . The dip-dyeing process of the present invention reduces the damage of rabbit down fibers, reduces the short-lint rate, and the short-lint rate is 9.7%-14.2%; improves the strength of the spun yarn in the spinning process, improves the evenness, improves the spinnability of the spinning process, and improves the spinning process In-process production rate. The process of the invention shortens the dyeing time, reduces energy consumption and environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of fiber dyeing, and in particular relates to a dip-dyeing process for rabbit down fibers with low short-down breakage rate. Background technique [0002] Rabbit hair fiber is smooth, soft, white, slender and shiny, and is a precious raw material for wool spinning. my country is a big country of rabbit hair production, the output accounts for 80%-90% of the world output, and the resources are very rich. The high proportion of rabbit fur products produced with rabbit fur as the main textile raw material has a unique style such as fine suede, smooth, waxy and soft feel, sufficient elasticity, lightness, comfort, warmth and beauty, and has won the favor of consumers at home and abroad. The market demand is large and the prospect is very broad. [0003] The scale structure of rabbit hair fiber is more complex than that of wool, with fewer scales, smaller scale tip angles, tighter wrapping with the hair shaft, ...
