Problems solved by technology

The bulkiness and softness of the existing products of this type are not enough
[0004] The traditional process of hot air diversion layer is complicated. Firstly, two kinds of long fibers must be made, and then the two kinds of long fibers are cut into 5-10cm long short fibers, and then the short fibers are broken up, and the two kinds of short fibers are mixed. The carding machine re-cards to obtain the fiber web, and melts and bonds two kinds of fibers with different melting points into a non-woven fabric by hot air
The process is long, the production speed is slow, the output is low, and the relative energy consumption is relatively high

Embodiment 1

[0058] As shown in accompanying drawing, the production method of the cloud cotton nonwoven fabric of a kind of spunbond method of the present invention, the step of this method comprises:

[0059] (1) Mix and stir low melt index polypropylene raw materials, low melt index propylene polymer raw materials and erucic acid fatty acid amide masterbatch;

[0060] (2) Extrude and melt the mixed and stirred raw materials through the feeding system to the screw to obtain a hot melt;

[0061] (3) Filtrating, metering and distributing the hot melt at a certain temperature and pressure;

[0062] (4) Spinning the distributed and metered hot melt, and cooling the spun filaments with side cooling air to obtain primary growth filaments;

[0063] (5) stretching the primary filaments to obtain fibers;

[0064] (6) Laying the fibers into a web to form a fiber web;

[0065] (7) After the fiber web is hot-rolled, a non-woven fabric is obtained;

[0066] (8) The non-woven fabric is stretched m...

Embodiment 2

[0076] The production method of the cloud cotton nonwoven fabric of the spunbonding method, the steps of the method include:

[0077] (1) First, the polypropylene raw material with a melt index of 35-38g / 10min, the propylene polymer raw material with a melt index of 48-52g / 10min, and the masterbatch of erucic acid fatty acid amide are mixed according to 74.5%:25.0%:0.5% The weight ratio is mixed;

[0078] (2) Add the above-mentioned mixed materials into the screw extruder through the feeding system for melting and extrusion to obtain a hot melt. The melting temperature of the screw is 180°C to 270°C;

[0079] (3) Filter the hot melt through a filtration system, measure and distribute it through a metering pump, the temperature is 230-250°C, and the pressure is 5-10MPa;

[0080] (4) Spray the filtered, metered and distributed hot melt through the spinneret from a hole diameter of 0.3-0.8mm, and cool it through the side-cooling air cooling system. The temperature of the side-co...

Abstract

The invention provides a method for producing non-woven cloud cotton fabric with a spun-bonded method, and belongs to the technical field of non-woven fabric. The method comprises the steps of mixing and stirring low-melting-index raw materials; conveying stirred raw material to a screw rod through a feeding system to be extruded and melted to obtain hot melts; conducting spinning on the hot melts, and cooling spun silk with side cold air to obtain initial filaments; pulling the initial filaments, and obtaining fibers with a certain fineness; dividing the fibers and conducting lapping to obtain fiber nets; obtaining non-woven fabric after the fiber nets are hot-rolled; stretching the non-woven fabric several times by the speed difference between a rolling mill, a finishing machine and a winder, wherein stretched non-woven fabric materials are preheated through hot air and high temperature in the stretching process to make products fluffy and soft, and have transverse micro-elasticity, and then winding the stretched non-woven fabric materials to form the non-woven cloud cotton fabric after the materials are molded through a cooling molding machine. Through the adoption of the method for producing the non-woven cloud cotton fabric with the spun-bonded method, the production efficiency,, the production speed and the yield are high, the production process is simple, and the production is quickly and conveniently completed at a time.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabric production, in particular to a production method of cloud cotton nonwoven fabric by spunbonding method. Background technique [0002] With the abundance of materials and the improvement of living standards, people have higher and higher requirements for the comfort and quality of disposable sanitary products such as baby diapers / diapers, adult diapers / diapers, and women's sanitary napkins. In particular, the softness of the product and the comfort of the product touch have higher requirements. Conventional disposable hygiene products generally use conventional silk and cotton soft spunbond nonwovens or hot-air products. Among them, conventional spunbond products have the characteristics of wear resistance, no shedding, high strength, high output, and low cost. There are certain defects in soft comfort and bulkiness; hot air products have the characteristics of fluffy and comfortable, but ...
