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 invention relates to the technical field of textile, and provides a flocking method for a spunlace nonwoven fabric, which aims at solving the problem of liability in removal of the flocks on the spunlace nonwoven fabric due to water washing. The flocking method specifically comprises the following steps of (1) applying of adhesive: applying the melted heat melt adhesive to the outer surface ofthe spunlace nonwoven fabric; (2) flocking: implanting the flocks to the surface of the spunlace nonwoven fabric by electrostatic charge, and arranging a heater in a flocking chamber; (3) dewatering:soaking the spunlace nonwoven flocked fabric after electrostatic flocking into water, and centrifugally dewatering; (4) drying: putting the spunlace nonwoven flocked fabric in step (3) into a dryer for drying, and finally coiling. The flocking method has the advantage that after water soaking and centrifugal dewatering, the un-firmly adhered flocks on the spunlace nonwoven fabric can be easily washed out, so as to improve the flocking firmness of the spunlace nonwoven flocked fabric, and avoid the liability in removal of the flocks on the spunlace nonwoven flocked fabric.

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...
