Problems solved by technology

[0003] At present, the preparation process of waterproof and oil-proof fabrics mainly adopts the following methods: (1) cloth base and functional layer are formed by heat sealing, such as patent No. 200810070553.9, the air permeability and softness of this process cloth are poor; Oil repellant, such as patent No. 201410371764.1, although this method is simple, but the prepared fabric is prone to color migration

Embodiment 1

[0039] 1) Singeing treatment: Singeing the cotton gray cloth at a temperature of 1000°C and a speed of 140m / min, using gas singeing technology to obtain a singeing cotton cloth;

[0040] 2) Deboiling and bleaching pile: the singeing cotton cloth is sequentially processed as follows, padding is mixed with a concentration of 16g / LH2O2, 15g / L clean cotton enzyme and 13g / L three-in-one auxiliary agent. PH=8, temperature Treat in cold pile liquid at 30°C for 5 minutes; roll up; stack for 21 hours; get cold pile cotton cloth;

[0041] 3) Flat washing: wash the above-mentioned cold-pile cotton cloth in deionized water successively for 2 hot water washes and 3 cold water washes to obtain a flat wash cotton cloth;

[0042] 4) Mercerizing: The above-mentioned plain washed cotton cloth is subjected to liquid ammonia mercerizing treatment, followed by the following treatments: pre-baking at 110°C under normal pressure for 7 minutes; cooling to room temperature; soaking in liquid ammonia a...

Embodiment 2

[0048] Process step is the same as embodiment 1, and difference is step (8) embossing pressure 100Kg / cm, speed 20m / min.

Embodiment 3

[0050] Process step is the same as embodiment 2, and difference is that step (7) coating amount 80g / m .

[0051] The single-sided waterproof and oil-proof cotton cloths prepared in Examples 1-3 all meet the performance requirements of waterproof and oil-proof cloths currently on the market. Considering comprehensively, the preparation process parameters of Example 2 are better.

Abstract

The invention discloses a preparation process of grey cotton cloth. The preparation process sequentially comprises the following steps: singeing treatment: carrying out singeing treatment on cotton fabric to obtain singed cotton cloth; desizing, scouring, bleaching and cold batching: putting the singed cotton cloth into a cold batching liquid for cold batching treatment so as to obtain cold batched cotton cloth; broad washing: carrying out broad washing on the cold batched cotton cloth so as to obtain broad washed cotton cloth; mercerizing: carrying out mercerizing treatment on the broad washed cotton cloth so as to obtain mercerized cotton cloth; dyeing: carrying out dyeing treatment on the mercerized cotton cloth so as to obtain dyed cotton cloth; shaping: shaping the dyed cotton cloth so as to obtain the shaped cotton cloth; and coating a waterproof and oil proof layer: coating one side of the shaped cotton cloth with waterproof and oil proof glue so as to obtain a single-side waterproof and oil proof cotton cloth. According to the preparation process provided by the invention, innovation is carried out on an aspect of after-treatment processing, a process of combining waterproof and oil proof coating and calendaring is adopted, and the grey cotton cloth prepared by using the preparation process has the advantages that the grey cotton cloth is soft, water-proof and oil proof, is prevented from environment pollution caused by bleaching, and conform to the concept of going green and environmental protection, and sustainable development.

Description

technical field [0001] The invention specifically relates to a preparation process of uncolored cotton cloth, and belongs to the field of textile fabrics. Background technique [0002] In the current society, water and oil are common pollutants in people's clothing fabrics and other fabrics in daily life and work, especially fabrics used in some special environments are more susceptible to water, oil and other dirt. Station pollution, such as machinery manufacturing, equipment maintenance, automobile industry and other industries, this puts forward new performance requirements for textiles. Waterproof and oil-proof textiles can prevent oily pollutants and water-based pollutants from standing stains, and the finished textiles hardly change the style of the original textiles, and do not produce fabric damage and spots. [0003] At present, the preparation process of waterproof and oil-proof fabrics mainly adopts the following methods: (1) cloth base and functional layer are f...
