Embodiment 1

[0012] Example 1: The white base of ultra-fine denier nylon fabric used in this embodiment: warp direction: 15D / 12f nylon low elastic yarn; weft direction: 20D / 24f nylon filament; door width 162cm; square meter weight 33g / m 2 .

[0013] The pretreatment of superfine denier nylon fabric is carried out in the following steps in the present embodiment:

[0014] S1. Using the HLM2082 cold batch machine, under the conditions of reaction temperature of 45°C and vehicle speed of 50m / min, cold pad batch treatment is carried out on the white blank of ultra-fine denier nylon fabric with cold stack liquid, and the ultra-fine denier nylon fabric is completed The pre-treatment; wherein the cold stack fluid described in step 2 is composed of 32% liquid caustic soda, degreasing agent TF-126A, hydrogen peroxide, high-efficiency refining penetrating agent TF-125D, chelating dispersant TF-510C, environmental protection low alkali cold stack king HLD -100, desizing agent M-1011 and water; the c...

Abstract

The invention discloses a pretreatment method of superfine denier nylon fabric, and belongs to the field of the processing of superfine denier nylon fabric. The method solves the technical problems that the strength of gray fabric is highly damaged by the existing pretreatment method of superfine denier nylon fabric, the feeling is not fluffy, and drape is easy to produce. The method comprises the following steps of: firstly, performing cold pad-batch processing to grey of superfine denier nylon fabric with cold batch liquid under the conditions that the reaction temperature is 40 to 45 DEG C and the lathing speed is 50 to 55m / min, and secondly, laying the grey of the superfine denier nylon fabric processed in the first step in an open-width desizing machine, and performing cold batch desizing processing with pad-batch desizing liquid under conditions that the reaction temperature is 95 to 98 DEG C and the lathing speed is 60 to 55m / min, so as to accomplish the pretreatment of the superfine denier nylon fabric. The method is applied to the pretreatment of superfine denier nylon fabric.

Description

technical field [0001] The invention relates to the field of processing ultrafine denier nylon fabrics, in particular to a pretreatment method for ultrafine denier nylon fabrics. Background technique [0002] Ultra-fine denier nylon fabric (chemical fiber with single filament fineness less than 0.9dtex) is soft to the touch, and the fabric surface has a uniform and dense uneven crepe feeling, which is not easy to fit and makes people feel cool and comfortable. And it has the functions of anti-rain and anti-ultraviolet, so that people can easily cope with climate change while enjoying nature. [0003] However, before fabric weaving, in order to improve the strength and wear resistance of warp yarns and reduce warp breakage, the yarns as warp yarns generally need to be treated with sizing, oiling agents and other medicaments. If these impurities and dirt are not removed, it will not only affect the feel and color of the fabric, but also affect the hygroscopicity of the fabric...
