Embodiment 1

[0030] An online continuous production process of absorbent cotton spunlace non-woven fabrics, comprising the steps of:

[0031] (1) Raw cotton loosening and impurity removal: After the cotton block is sent into the beating chamber of the axial flow opener, under the joint action of the beating hands and the air flow, the beating hands make a spiral movement, and are successively received by the rectangular blades and rods on the beating hands. Opening and cleaning of shaped brad nails and V-shaped brad nails in the form of striking;

[0032] (2) degreasing and bleaching: remove the wax or grease on the cotton fiber, and then bleach;

[0033] (3) Drying: Drying is carried out in a dryer, and the temperature is controlled at about 120°C;

[0034] (4) Fan conveying: transported by the conveying fan to the cotton mixing box;

[0035] (5) Opening;

[0036] (6) Carding into a web: using a high-speed messy carding machine to card into a web;

[0037] (7) Spunlace: use high-press...

Embodiment 2

[0040] An online continuous production process of absorbent cotton spunlace non-woven fabrics, comprising the steps of:

[0041] (1) Raw cotton loosening and impurity removal: After the cotton block is sent into the beating chamber of the axial flow opener, under the joint action of the beating hands and the air flow, the beating hands make a spiral movement, and are successively received by the rectangular blades and rods on the beating hands. Opening and cleaning of shaped brad nails and V-shaped brad nails in the form of striking;

[0042] (2) Carding into a web: using a high-speed messy carding machine to card into a web;

[0043] (3) Spunlace: use high-pressure water flow to entangle the cotton web;

[0044] (4) rolling degreasing;

[0045] (5) washing with water;

[0046] (6) Drying and coiling.

Abstract

The invention belongs to the field of nonwoven fabric production processes and particularly relates to an online continuous production process of degreased cotton spunlace nonwoven fabric. The process fitly connects a degreased cotton step and a spunlace nonwoven fabric production step, the degreased cotton is dried and then fed directly into a spunlace nonwoven fabric mixing bin for seamless connection production, transfer cost for the degreased cotton is avoided, and pollution is avoided. Raw cotton is made into spunlace nonwoven fabric that is directly subjected to pressing for degreasing and bleaching, washing, and drying, a continuous mode is formed, and product transferring and deformation are avoided; the product yield can be greatly increased.

Description

technical field [0001] The invention belongs to the field of non-woven fabric production technology, in particular to an online continuous production process of absorbent cotton spunlace non-woven fabric. Background technique [0002] Non-woven fabric (non-woven fabric) is a kind of fabric formed without spinning and weaving. It just orients or randomly arranges short textile fibers or filaments to form a web structure, and then uses mechanical, thermal bonding or chemical bonding. Reinforced by other methods. To put it simply: it is not interwoven and knit together by yarns one by one, but the fibers are directly bonded together through physical methods, so when you get the sticky scale in your clothes , you will find that it is impossible to extract the thread ends one by one. Nonwovens have broken through the traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide application, and multiple so...
