Embodiment 1
[0057] like figure 1 , the preparation method of the spunlaced cloth provided by the embodiment of the present invention, comprising:
[0058] S101: carding, the material for carding is fiber or polyester or PTA; unwinding.
[0059] S102: add 8g-100g of wood pulp or cotton to spread or strip.
[0060] S103: secondary molding.
[0061] S104: Spunlace.
[0062] S105: drying.
[0063] S106: rewinding.
[0064] In step S103, after being processed by a coarse pulverizer, it is processed by a fine pulverizer, and the fluff pulp or cotton is quantified by a fiber collector, and then transported to the first forming area through a feeding fan; the cylinder net in the forming area is rotated to make The processed fluff pulp or cotton is fully or stripped on the forming wire under the action of negative pressure fan for secondary molding.

Abstract
The invention belongs to the technical field of papermaking, and discloses a preparation method of a spunlace fabric. The method comprises the steps that carding is carried out, wherein a carding material is fibers or polyester or PTA; forming is carried out to form a non-woven fabric; unwinding is conducted; 8-100 g of wood pulp or cotton is added for full laying or strip laying; the fluff pulp or cotton is treated by a coarse pulverizer, then treated by a fine pulverizer, and conveyed to a primary forming area through a feeding fan after being quantified by a fiber collection machine; through the rotation of a round cage net in the forming area, the treated fluff pulp or cotton is subjected to full laying or strip laying on the surface of a forming net under the action of a negative pressure fan for secondary forming. According to the method, the wood pulp or cotton is utilized, and the production cost is reduced; moreover, degradation is easy; the pollution is reduced.
Description
technical field [0001] The invention belongs to the technical field of papermaking, in particular to a method for preparing spunlace cloth. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] A preparation and application of antibacterial spunlace cloth without precipitation, comprising the following preparation steps: [0004] In the first step, one or more soluble metal salts and soluble rare earth element compounds are formulated into aqueous solutions, and are added dropwise to the organic complex solvent system during the ultrasonic cavitation process to form a stable water-in-oil system; [0005] The second step, the above-mentioned water-in-oil system was reacted in a 120-170°C reactor for 30-90min, cooled, centrifuged, and the precipitate was filtered to obtain a nano-antibacterial emulsion; [0006] The third step is to inject the nano antibacterial emulsion into the special crosslinking agent ...
