Embodiment 1

[0022] A preparation process of a non-woven foamed cushion material for automobile seat cushions, the specific steps are as follows: 1) mixing hydrophilic polyester fiber and back-spun polyester, stretching, carding, laying, and drafting to form a cotton net , using a blender to mix materials, stretching with an air-pressure cotton box, and using a web-laying machine to card, lay, and draft to make a cotton web; lay the cotton web made of hydrophilic polyester fibers on the cotton web of back-spun polyester , sent to the spunlace reinforcement area for simultaneous spunlace reinforcement to make a double-layer non-woven fabric; 4) winding double-layer non-woven fabric.

[0023] The hydrophilic group in the hydrophilic polyester fiber is a hydroxyl group. The back-spun polyester is polyethylene terephthalate resin. The spunlace reinforcement treatment adopts drum spunlace reinforcement, the number of spunlace heads is 10, the aperture of the spunlace plate is 0.1mm, and the de...

Embodiment 2

[0025] A preparation process of a non-woven foamed cushion material for automobile seat cushions, the specific steps are as follows: 1) mixing hydrophilic polyester fiber and back-spun polyester, stretching, carding, laying, and drafting to form a cotton net , using a blender to mix materials, stretching with an air-pressure cotton box, and using a web-laying machine to card, lay, and draft to make a cotton web; lay the cotton web made of hydrophilic polyester fibers on the double-layer back-spun polyester The middle of the cotton net is sent to the spunlace reinforcement area for simultaneous spunlace reinforcement to form a three-layer non-woven fabric; 4) winding the three-layer non-woven fabric.

[0026] The hydrophilic groups in the hydrophilic polyester fibers are carboxyl groups. The back-spun polyester is polyethylene terephthalate resin. The spunlace reinforcement treatment adopts drum spunlace reinforcement, the number of spunlace heads is 15, the aperture of the sp...

Embodiment 3

[0028] A preparation process of a non-woven foamed cushion material for automobile seat cushions. The specific steps are as follows: 1) The mixture of hydrophilic polyester fiber and low-melting point polyester fiber and the back-spun polyester are respectively mixed, stretched, carded, and spread. Cotton net is made by netting and drafting, which is mixed by a mixer, stretched by an air pressure cotton box, and carded, laid and drafted by a web lapper to form a cotton net; the cotton net made of mixed polyester fibers is laid On the back-spun polyester cotton net, send it to the spunlace reinforcement area for simultaneous spunlace reinforcement to make a double-layer non-woven fabric; 4), heat the double-layer non-woven fabric made; 5) Wind the double-layer non-woven fabric non-woven fabric.

[0029] The weight ratio of the hydrophilic polyester fiber to the low melting point polyester fiber is 9 / 1.

[0030] The hydrophilic groups in the hydrophilic polyester fibers are car...

Abstract

The invention discloses a non-woven fabric foaming liner material for an automobile seat cushion and a preparation process of the non-woven fabric foaming liner material. Hydrophilic polyester fibersand respun polyester are mixed, extended, carded, lapped and drafted to prepare cotton webs, and the prepared hydrophilic polyester fiber cotton web is laid on the respun polyester cotton web or in the middle of two layers of respun polyester cotton webs; meanwhile, spunlace reinforcement treatment is carried out, and the non-woven fabric foaming liner material is prepared. The process comprises the following steps that 1) the hydrophilic polyester fibers and polyester fibers are mixed, extended, carded, lapped and drafted to prepare the cotton webs; 2) the cotton web made of the hydrophilic polyester fibers is laid on the cotton web made of the respun polyester or in the middle of two layers of respun polyester cotton webs, a product is sent to a spunlace reinforcing area for spunlace reinforcement to obtain a double-layer non-woven fabric or a three-layer non-woven fabric; and (4), the double-layer non-woven fabric or the three-layer non-woven fabric is wound. The non-woven fabric foaming liner material and the preparation process have the advantages that waste materials and old materials are easy to recycle, large waste is avoided, the recycling rate is high, and environmental pollution is small.

Description

technical field [0001] The invention relates to the technical field of automobile seat cushion production technology, in particular to a non-woven foamed cushion material for automobile seat cushions and a preparation process thereof. Background technique [0002] At present, the non-woven fabric of the foamed cushion material used in the car seat cushion is mainly made of PP spunbonded fabric plus back-spun PPT fiber mixed and manufactured by needle punching. This method is low in cost, but the leftovers cannot be recycled due to the two material components, causing great environmental pressure. This acupuncture method cannot guarantee the existence of a broken needle. The other is the patented product of Japan Toyobo, which is made of polyester melt spray. The cost of this method is higher, and it is not easy to recycle because the fiber is too long. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art...
