Embodiment Construction

[0021] The present application will be described in further detail below through specific embodiments in conjunction with the accompanying drawings.

[0022] The production process of the spunlace non-woven fabric given in this embodiment is as follows: figure 1 shown, including the following steps,

[0023] S10, laying net

[0024] Lay the raw cotton fiber after cleaning and carding through a web-laying machine to form a cotton web.

[0025] S20, spunlace

[0026] Spunlace the cotton web through a high-pressure water curtain to form a spunlace nonwoven fabric.

[0027] S30, steam bleaching

[0028] The spunlace non-woven fabric is steam bleached through a steam box. Specifically as figure 2 shown, including:

[0029] S31, squeezing water;

[0030] Reduce the moisture content of the non-woven fabric after spunlace by padding, and reduce the moisture content in the non-woven fabric from 150%-400% to 50%-100%. In this step, the non-woven fabric after spunlace does not n...

Abstract

A production technology of spunlaced non-woven fabric comprises the following steps: spunlacing, namely spunlacing a cotton net into non-woven fabric; performing steaming bleaching, namely immersing the spunlaced non-woven fabric into a bleaching aid, and bleaching in a steam box; washing, namely efficiently washing the non-woven fabric obtained after steaming bleaching to remove the residual bleaching aid; drying. In the production technology of the spunlaced non-woven fabric, provided by the invention, steam bleaching is adopted, and compared with the conventional boiling bleaching in a bleaching boiler, steaming bleaching has the advantages of low water consumption, low power consumption, energy saving and environment friendliness; the spunlacing step and the steaming bleaching step arecontinuously performed, and the non-woven fabric obtained after steaming bleaching is not required to be rolled, so that the production efficiency is improved and the problem of non-uniform bleachingof the rolled non-woven fabric in the boiler 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...
