Embodiment Construction

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

[0023] The production process of the spunlace non-woven fabric given in this embodiment is as follows: figure 1 shown, including the following steps,

[0024] S10, laying net

[0025] Lay the raw cotton fiber after cleaning and carding through a web-laying machine to form a cotton web.

[0026] S20, spunlace

[0027] Spunlace the cotton web through a high-pressure water curtain to form a spunlace nonwoven fabric.

[0028] S30, cold drift

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

[0030] S31, drying;

[0031] The non-woven fabric after spunlace is dried on-line.

[0032] S32, immersing in the bleaching aid;

[0033] Dip the dried non-woven fabric into the bleach aid. The non-woven fabric has been dried in step S31, which is beneficial to the abso...

Abstract

The invention discloses a production method of spunlace non-woven fabric. The production method comprises following steps: spunlace treatment, wherein cotton web is subjected to spunlace treatment soas to obtain non-woven fabric; cold bleaching, wherein non-woven fabric obtained via spunlace is subjected to drying, immersing in a bleaching auxiliary, and cold stacking treatment; water washing, wherein after cold bleaching, the non-woven fabric is subjected to water washing so as to remove residual bleaching auxiliary; and drying. Compared with conventional bleaching pot boiling bleaching method, the production method possesses following advantages: on-line cold bleaching is adopted, water consumption is reduced by 85%, electricity consumption is reduced by 60%, production cost is reducedgreatly, energy saving and environment protection are realized; continuous spunlace treatment and cold bleaching are adopted, so that production efficiency is increased, and nonuniform bleaching caused by rolling of non-woven fabric in bleaching pot boiling bleaching is avoided.

Description

technical field [0001] The application relates to the field of textiles, in particular to a production process of spunlace non-woven fabrics. Background technique [0002] In the existing production process of spunlace non-woven fabrics, the raw cotton fibers are debleached after cleaning, carding, net laying, spunlace, and rolling. The debleaching process is to put the wet non-woven fabric rolled up after spunlace into the bleaching pot, add a bleaching aid, raise the temperature to 105-120 degrees, boil and bleach for 4-5 hours, and then wash and dry. This process consumes a lot of water, high power consumption, and large steam consumption. It is not energy-saving, environmentally friendly, and has many procedures and complicated operations. A coiling step is also required between the spunlace step and the debleaching step, resulting in discontinuous spunlace and debleaching steps and low production efficiency. Contents of the invention [0003] The present application...
