Problems solved by technology

[0002] In the existing production process of cotton spunlace nonwovens, multiple winding and roll changing operations are required from raw materials to finished products. The production process is not continuous, which makes the production efficiency of cotton spunlace nonwovens low
In addition, most of the existing surgical gowns are blue or green. The purpose is to alleviate the visual fatigue caused

Embodiment 1

[0034] After the raw cotton is cleaned, carded, carded and cross-laid, it is fed into the spunlace machine for pre-wetting of the cotton net. The pressure is 55bar, followed by 4 drum spunlace machine spunlace, the pressure of the spunlace head is 57bar, 62bar, 63bar, 65bar in turn;

[0035] The non-woven fabric after spunlace is dipped and squeezed respectively at room temperature. The chemical formula for padding is: refining agent 3g / L, stabilizer 3g / L, caustic soda 15g / L, hydrogen peroxide 20g / L, of which hydrogen peroxide The mass concentration is 27.5%;

[0036] The non-woven fabric after padding chemicals is sent into the steamer for steaming, scouring and bleaching. The steaming temperature is 98°C, and the steaming time is 3 minutes;

[0037] Then perform a normal temperature water wash and a 70°C hot water wash;

[0038] Pickling the washed non-woven fabric, adding concentrated sulfuric acid with a concentration of 98% to the water, and the concentrated sulfuric ac...

Embodiment 2

[0045] After the raw cotton is cleaned, carded, carded and cross-laid, it is fed into the spunlace machine for pre-wetting of the cotton net. The pressure is 50bar, followed by 4 drum spunlace machine spunlace, the pressure of the spunlace head is 52bar, 56bar, 58bar, 60bar;

[0046] The non-woven fabric after spunlace is dipped and squeezed respectively at room temperature. The chemical formula for padding is: refining agent 2.5g / L, stabilizer 2.5g / L, caustic soda 15g / L, hydrogen peroxide 18g / L, Wherein the mass concentration of hydrogen peroxide is 27.5%;

[0047] The non-woven fabric after padding chemicals is sent into the steamer for steaming, scouring and bleaching. The steaming temperature is 98°C, and the steaming time is 3 minutes;

[0048] Then perform a normal temperature water wash and a 70°C hot water wash;

Abstract

The invention relates to the technical field of non-woven fabrics, in particular to a continuous production method of an all-cotton spunlace three-resistance non-woven fabric. The continuous production method comprises the following steps that blowing, cotton carding, carding, lapping, spunlace, chemical padding, bleaching, continuous washing, acid pickling, finishing liquid padding, baking and calendering treatment are sequentially carried out on raw cotton, then a finished product is slit and wound, and thus the all-cotton spunlace three-resistance non-woven fabric can be obtained. Accordingto the continuous production method, the whole production process is continuously operated, frequent winding and roll changing are not needed, continuous production can be achieved, shutdown is avoided, and the purposes of shortening the production time, improving the production efficiency, reducing the labor intensity of workers, reducing the labor cost and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a continuous production method and application of all-cotton spunlace three-resistant non-woven fabrics and three-resistant surgical gowns. Background technique [0002] In the existing production process of cotton spunlace nonwovens, multiple winding and roll changing operations are required from raw materials to finished products. The production process is not continuous, which makes the production efficiency of cotton spunlace nonwovens low. In addition, most of the existing surgical gowns are blue or green. The purpose is to alleviate the visual fatigue caused by medical staff staring at the red color for a long time during the operation. However, most of the existing fabrics used to produce surgical gowns are directly made of dyed fabrics. As a result, dyeing and three-antibody finishing are carried out separately, which causes problems such as long time consumpti...
