Embodiment 1

[0044] A kind of flocking method of spunlace nonwoven fabric, comprises the following concrete steps:

[0045] (1) Gluing, as follows:

[0046] Heat the hot melt adhesive to 130°C to make the hot melt adhesive in a molten state, and then apply the molten hot melt adhesive evenly on the outer surface of the spunlace nonwoven fabric to form an adhesive layer.

[0047] Hot melt adhesives include the following components in parts by mass:

[0048] 84 parts of ethylene-acrylic acid copolymer; 52.5 parts of thermoplastic polyurethane elastomer rubber; 7.5 parts of silicon micropowder; 3 parts of silane coupling agent.

[0049] The preparation method of adhesive is as follows:

[0050] In a 200L stirred tank, under normal temperature, add 84 kg of ethylene-acrylic acid copolymer, stir at a speed of 40 r / min, add thermoplastic polyurethane elastomer rubber, silicon micropowder, and silane coupling agent while stirring, and stir for 15 minutes to form a pre- Put the premix into the ...

Abstract

The present invention relates to the field of textile technology. Aiming at the problem that spunlace nonwoven flocking fabrics are easy to delint after washing, a flocking method of spunlace nonwoven fabrics is provided. Melt adhesive is applied on the outer surface of the spunlace nonwoven fabric; (2) Flocking: use static electricity to implant fluff into the surface of the spunlace nonwoven fabric, and a heater is installed in the flocking room; (3) Dehydration treatment: the electrostatic flocking will be completed The cashmere spunlace non-woven flocking fabric is soaked in water and centrifugally dehydrated; (4) drying: put the spunlace non-woven flocking fabric in step (3) into a dryer for drying, and finally wind up. Through water soaking treatment and centrifugal dehydration treatment, the fluff that is not firmly bonded on the spunlace nonwoven fabric is easily washed out, which is conducive to improving the flocking fastness of the spunlace nonwoven flocking fabric, making the spunlace nonwoven flocking The fluff on the cloth is not easy to take off.

Description

technical field [0001] The invention relates to the field of textile technology, more specifically, it relates to a method for flocking spunlace nonwoven fabrics. Background technique [0002] Spunlaced non-woven flocking fabric uses the physical characteristics of same-sex repulsion and opposite-sex attraction to make the fluff negatively charged, and then put the spunlace non-woven fabric that needs flocking under zero potential or grounding conditions, and the fluff will The potential is attracted by the spunlace non-woven fabric, and accelerates to the surface of the spunlace non-woven fabric vertically. Since the surface of the spunlace non-woven fabric is coated with adhesive, the fluff is vertically stuck to the spunlace non-woven fabric. Spunlace non-woven flocking fabrics have been widely used in industries such as furniture, handicrafts and bags. [0003] However, the existing spunlace non-woven flocking cloth is troublesome to clean. When cleaning, it is necessar...
