Embodiment 1

[0027] A short-process dyeing and finishing process of multi-component fiber-coated elastic yarn. In this process, the composition of the raw material multi-component fiber-coated elastic yarn is 50P40R8N2PBT, 50S / 2. The specific process of the process is as follows:

[0028] 1. One-step dyeing: put the multi-component fiber-coated elastic yarn to be dyed into the dye vat of the dyeing equipment, and immerse it in water, add auxiliary agents in the dye vat of the dyeing equipment, the amount of auxiliary agents is: dispersant 0.5g / L and base release agent 0.2g / L, after soaking for 5 minutes, add disperse dyes, the dosage of disperse dyes is DZF yellow 0.07 (o.w.f), DZF red 0.26 (o.w.f), DZF blue 0.15 (o.w.f), soak for 5 minutes, add active Dye, the amount of reactive dyes is CN Yellow 0.15 (o.w.f), CN Red 0.37 (o.w.f), CN Blue 0.60 (o.w.f), soak for 5 minutes, add sodium sulfate and dyeing aids for reactive dyeing, sodium sulfate (yuan Mingfen) The dosage is 18g / L, the dyeing...

Embodiment 2

[0033] A short-process dyeing and finishing process of multi-component fiber-coated elastic yarn. In this process, the composition of the raw material multi-component fiber-coated elastic yarn is 60P38R2PBT, 50S / 2. The specific process of the process is as follows:

[0034] The yarn selected in this example uses PBT filament as the core thread. After the dyeing process is completed, due to the difference in fiber shrinkage performance, the yarn surface structure is novel, and the elasticity and recovery performance are superior.

[0035] 1. One-step dyeing: put the multi-component fiber-coated elastic yarn to be dyed into the dye vat of the dyeing equipment, and immerse it in water, add auxiliary agents in the dye vat of the dyeing equipment, the amount of auxiliary agents is: dispersant 0.5g / L and alkali release agent 0.2g / L, after soaking for 5 minutes, add disperse dyes, the dosage of disperse dyes is DZF yellow 0.12 (o.w.f), DZF red 0.28 (o.w.f), DZF blue 0.10 (o.w.f), soa...

Abstract

The invention relates to an elastic yarn production technology, in particular to a short-process dyeing and finishing technology of multi-component fiber covered type elastic yarn. The technology comprises processes as follows: (1) one-step dyeing: to-be-dyed multi-component fiber covered type elastic yarn is put in a dyeing vat of dyeing equipment and soaked in water, an aid is added, disperse dye is added after the yarn is soaked for 5-8 min, active dye is added after the yarn is soaked for 5-8 min, sodium sulfate and a dyeing auxiliary are added for active dyeing after the yarn is soaked for 5-8 min, the dyeing temperature is controlled at 95-98 DEG C, the dyeing time lasts for 30-60 min, and the bath ratio is 1: (8-10); the dyed multi-component fiber covered type elastic yarn is dewatered in a dewatering machine; (2) fixation: the multi-component fiber covered type elastic yarn is washed with hot water at the temperature of 60-65 DEG C for 15-20 min and then cooled to the room temperature; (3) softening treatment: a softening agent is added for softening the multi-component fiber covered type elastic yarn, the softened multi-component fiber covered type elastic yarn is cooled to the room temperature, and a product is obtained.

Description

technical field [0001] The invention relates to a production process of elastic yarn, in particular to a short-process dyeing and finishing process of multi-component fiber-coated elastic yarn. Background technique [0002] The existing multi-component fiber-coated elastic yarn skein dyeing process is relatively complicated. When dyeing, the dye needs to be dispersed first, after adding additives, heat it to about 100°C and keep it warm, then cool it down to room temperature, and restore cleaning; Dyeing needs to be divided into five steps: ①Add sodium sulfate and a part of alkali to the dispersed dye, mix well, heat to 60°C and keep it warm, then continue to add alkali, ②Wash in hot water at 60°C, drop to room temperature, ③Pickling, wash in hot water , down to room temperature, ④ 95 ℃ soaping, ⑤ continue to wash with hot water, down to room temperature, ⑥ add softener, down to room temperature. So far, a dyeing process is completed. Generally, the two-bath two-step dyein...
