Embodiment Construction

[0021] The specific implementation of the present invention will be described in detail below in conjunction with preferred embodiments.

[0022] A kind of dyeing method that nylon elastic yarn is made cheese, carries out according to the following steps,

[0023] 1) Loose winding: SSM winding machine is adopted, the winding speed is 300-700r / min, the back pressure is 40-52%, the tension is 30-60%, the winding angle is 11°-18°, the loose winding bobbin is fixed Weight is 0.8-1.2kg / piece, density is 0.35-0.40g / cm 3 ;

[0024] 2) Pre-treatment: After injecting water into the dyeing vat at a bath ratio of 1:20, add 0.5-2g / L soaping agent, raise the temperature of the dyeing bath to 80°C and keep it warm for 15 minutes, and empty it after treatment; refill the dyeing vat at a bath ratio of 1:20 , after running for 5 minutes, empty after processing;

[0025] 3) Bomb reduction: After filling the dye vat with water at a process bath ratio of 1:20, the temperature of the dye bath i...

Abstract

The invention belongs to the technical field of textiles, and particularly relates to a dyeing method for cheese made of nylon stretch yarns, and the method comprises the following steps of: loose winding, pre-treatment, dyeing, post-treatment and dewatering, and is characterized in that the steps of elasticity lowering, dewatering and loose secondary winding are added between pre-treatment and dyeing, so that the whole process comprises loose winding, pre-treatment, elasticity reducing, dewatering, loose secondary winding, dyeing, post-treatment and dewatering. The dyeing method has the beneficial effects that the steps of elasticity reducing, dewatering and loose secondary winding are added between pre-treatment and dyeing, so that the interior and exterior of the cheese are uniform in color and elasticity, the success rate for one dyeing is high, and the problems brought by the conventional method are avoided.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for dyeing cheeses made of nylon elastic yarns. Background technique [0002] Multi-component yarn-dyed fabrics have always been the new favorite of high-end clothing and fashion designers. Nylon elastic yarns are used in yarn-dyed fabrics. The cloth is not enough in color, feel, single material, etc. Nylon cotton interwoven elastic fabric meets people's pursuit of individuality, comfort and fashion. However, nylon elastic yarn is different from cotton elastic yarn in package yarn. The nylon dyeing method in the prior art has problems such as impervious dyeing, inconsistent elasticity inside and outside the package, and difficult color control. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned technologies, and provide a method for dyeing nylon elastic yarn as package yarn, addin...
