Title:
ACID LOW-TEMPERATURE DIP DYEING METHOD FOR POLYAMIDE 56 FIBER AND FABRIC
Document Type and Number:
WIPO Patent Application WO/2021/136411
Kind Code:
A1
Abstract:
The present invention discloses an acid low-temperature dip dyeing method for a polyamide 56 fiber and fabric. The dyeing method of the present invention comprises the following step: using an acidic dye, a neutral dye or an active dye to dye a polyamide 56 fiber or a fabric thereof. The method has the following advantages: (1) a good dyeing effect, a deep color yield, and a high dye uptake rate; (2) a good color fastness, and the level of rub resistance and wash resistance reaching up to four or above, and the level of color fastness to sunlight reaching up to six or above; and (3) a simple process flow, energy-saving and emission reduction, and being a dyeing method for quick dye uptake at a low temperature and within a short time, low-temperature dyeing effectively reducing damage to a fiber during dyeing, reducing the weight loss rate of the fiber, and facilitating increasing the production rate of a post-process product.
