Raw cotton cold stack skilled water spin -free woven production process

Abstract

The invention discloses a spunlace non-woven fabric production process for degreasing cold piles of raw cotton. The spunlace non-woven fabric production process includes steps of 1), opening the raw cotton and removing impurities from the raw cotton; 2), filling the raw cotton with liquid and caking the raw cotton; 3), rotationally piling up the raw cotton at the normal temperature; 4), washing the raw cotton at the normal temperature; 5), opening and drying the raw cotton; 6), carding the raw cotton and forming nets; 7), carrying out spunlace fixed net jacquard; 8), vacuumizing and drying the nets; 9), winding and slitting the nets. The spunlace non-woven fabric production process has the advantages that the cold piles of the raw cotton are directly degreased, dried degreased cotton and pure cotton spunlace yarns are produced in an online manner, and accordingly the purposes of saving energy and energy sources, reducing emission and intermediate transfer links, improving production environments, quickly carrying out circulation and enhancing the product manufacturing control ability can be achieved; the problem that pure cotton spunlace non-woven fabrics only can be degreased at required high temperatures in liquid immersion press-rolling working procedures by existing cold piling pure cotton spunlace non-woven fabric production processes can be solved.

Description

technical field [0001] The application relates to the technical field of non-woven fabric production, in particular to a spunlace non-woven fabric production process for cold stack degreasing of raw cotton. Background technique [0002] At present, the production of pure cotton spunlace non-woven fabrics is made of pure cotton spunlace non-woven fabrics made of raw cotton that is boiled and bleached at high temperature to become absorbent cotton, or raw cotton that is processed by spunlace and then boiled and bleached at high temperature. The two processes, whether cotton or raw cotton is made into cloth, need to be boiled and bleached at high temperature; the former processing technology has strict requirements on production technology and production equipment, which wastes water, electricity and steam energy; The diverse needs of surface styles. [0003] In addition, the existing cold pile method pure cotton spunlace non-woven fabric production process is to degrease the ...

Problems solved by technology

The two processes, whether cotton or raw cotton is made into cloth, need to be boiled and bleached at high temperature; the former processing technology has strict requirements on production technology and production equipment, which wastes water, electricity and steam energy; Diversified needs for surface styles

[0003] In addition, the existing cold pile method pure cotton spunlace non-woven fabric production process is to degrease the pure cotton spunlace non-woven fabric, which needs high temperature (generally 105-135 degrees Celsius) in the dipping hydraulic rolling process to degrease Require
