Problems solved by technology

[0003] Although the finished swimming trunks made of nylon fabric used in the existing swimming trunks processing have good elasticity and softness, the affinity of nylon fabrics to dyes is average, especially after the swimming trunks are soaked in water for a long time, their wet fastness is average. Easy to fade and fade, which greatly affects the appearance of swimming trunks

Embodiment 1

[0020] A treatment method for improving the dye fastness of nylon fabrics for swimming trunks, comprising the following steps:

[0021] (1) Preparation of pretreatment agent: Mix oxalic acid and malonamide evenly according to the mass ratio of 3:1.4, add them to the reaction kettle, pass inert gas, remove the air in the reaction kettle, then heat it to 40°C in a water bath, and keep it warm 10min, then add glycolic acid with 0.5% oxalic acid mass, stir evenly, then adjust the pH of the mixed system to 5.0, heat to 65°C, keep the temperature for 3 hours, then cool and discharge to obtain a mixed product, which is obtained by pressing 1:10 mass ratio is dissolved in organic solvent to obtain pretreatment agent;

[0022] (2) Nylon fabric pretreatment: Soak the nylon fabric in a weak alkaline solution for 10 minutes, then filter, wash with clean water until neutral, and dry naturally;

[0023] (3) Pretreatment agent treatment: Mix the above-mentioned treated nylon fabric with the...

Abstract

The invention discloses a treatment method for improving colour fastness of a chinlon fabric used for swimming trunks, and relates to the technical field of costume fabrics. The method comprises the following steps of (1) pre-treatment agent preparation, (2) chinlon fabric pre-treatment and (3) pre-treatment agent treatment. Chinlon treated through the method has better dyeing performance, and theswimming trunks prepared from the chinlon subjected to dyeing is fadeless and not stained when soaked in water for a long term, so that the service life of the swimming trunks is significantly prolonged.

Description

technical field [0001] The invention belongs to the technical field of apparel fabrics, and in particular relates to a treatment method for improving the dye fastness of nylon fabrics for swimming trunks. Background technique [0002] Swimming trunks are clothing worn by men for swimming, diving or water-related activities. The shape is similar to panties, but the fabric is usually different. Swimming trunks are mainly divided into triangles and flat corners, thongs and other categories. Ordinary swimming trunks are mostly in dark tones such as dark blue and black. There are also swim trunks in bright yellow, green, red and other bright colors. [0003] Although the finished swimming trunks made of nylon fabric used in the existing swimming trunks processing have good elasticity and softness, the affinity of nylon fabrics to dyes is average, especially after the swimming trunks are soaked in water for a long time, their wet fastness is average. It is easy to fade and fad...
