Embodiment Construction

[0022] The present application will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0023] The production technology of the spunlace non-woven fabric provided in the present embodiment is as follows figure 1 shown, including the following steps,

[0024] S10, laying net

[0025] The raw cotton fibers that have been cleaned and carded are laid by a web laying machine to form a cotton web.

[0026] S20, Spunlace

[0027] The cotton web is spunlaced through a high-pressure water curtain to form a spunlace non-woven fabric.

[0028] S30, cold drift

[0029] The spunlace non-woven fabric is treated by cold bleaching. Specifically as figure 2 shown, including:

[0030] S31, rolling water;

[0031] The spunlace non-woven fabric is subjected to a high-efficiency rolling mill for water-rolling treatment to reduce its moisture content, so that the moisture content in the non-woven fabric is reduced from 150%-400...

Abstract

The invention relates to a spunlace non-woven fabric production technology. The technology comprises the steps of spunlace, wherein fleece is subjected to spunlace to form a non-woven fabric; cold bleaching, wherein the non-woven fabric obtained after spunlace is subjected to squeezing through a padder and then immersed in bleaching auxiliaries, and then cold pad-batch is conducted; water washing,wherein the non-woven fabric obtained after cold bleaching is subjected to water washing, and the residual bleaching auxiliaries are removed; drying. According to the spunlace non-woven fabric production technology, online synchronous cold bleaching is conducted through spunlace; compared with existing bleach pot boiling and bleaching, water consumption can be decreased by 85%, power consumptionis lowered by 70%, the production cost is greatly lowered, and energy conservation and environmental friendliness are achieved; spunlace and cold bleaching are conducted continuously, the production efficiency is improved, and the problem that after the non-woven fabric rolls, nonuniform bleaching occurs in the pot boiling and bleaching process is avoided.

Description

technical field [0001] The present application relates to the field of textiles, and in particular, to a production process of a spunlace non-woven fabric. Background technique [0002] In the production process of the existing spunlace non-woven fabric, the raw cotton fibers are subjected to cleaning, carding, net laying, spunlace, and rolling, and then debleached. The debleaching process is to put the wet non-woven fabric rolled after spunlace into a bleaching pot, add a bleaching aid, heat up at 105-120 degrees, boil and bleach for 4-5 hours, and then wash and dry. This process consumes a lot of water, electricity, and steam. A rolling step is also required between the spunlace step and the deleaching step, resulting in discontinuous spunlace and deleaching steps and low production efficiency. SUMMARY OF THE INVENTION [0003] The present application provides a production process of a spunlace non-woven fabric, which aims to solve the problems of high cost and unenvir...
