Problems solved by technology

Since the bottom of the carpet produced by this process needs a backing cloth, it must be wider than the tufted fabric on the upper layer during the melting process. Therefore, after compounding, it needs to be cut, which will cause a lot of waste and increase the cost.
The fleece-fixing effect of the film is not obvious, and the backing used is a flat base fabric, and there is no way to form an effective anti-skid effect at one time.

preparation example Construction

[0038] The invention provides a fully recyclable tufted chemical fiber carpet and a preparation method thereof, the method comprising the following steps:

[0039] S1. Selection of chemical fiber yarns: yarns spun from one or more chemical fibers, such as polyester, nylon, acrylic, polyvinyl chloride, polypropylene and other chemical fiber yarns.

[0040] S2. Selection of composite base cloth: use chemical fiber woven or knitted fabric as the base material, lay chemical fiber short fibers on the base material, and then enter the non-woven needle punching machine to form a composite base cloth to obtain a composite base cloth (which is made of chemical fiber woven or Knitted fabric layer and needle-punched chemical fiber non-woven fabric layer) After being rolled up, hot ironing rods are used to carry out ironing treatment to enhance the adhesion of fibers and the flatness of composite base cloth (also can not be ironed).

[0041] The terminology of "non-woven needling processi...

Embodiment 1

[0050] This embodiment relates to a fully recyclable tufted chemical fiber carpet, such as figure 1 shown, including:

[0051] Carpet surface: cut pile layer 1,

[0052] Base fabric layer: composed of base material layer 2 and needle-punched non-woven fabric layer 3; the bottom of needle-punched non-woven fabric layer 3 is a melted and solidified structure formed by melting and solidifying the tufted yarn roots and needle-punched non-woven fabric layer 3 layer.

[0053] The preparation of the fully recyclable tufted chemical fiber carpet comprises the steps:

[0054] 1) Selection of yarn: Select the thickness of 4500DTX polypropylene stock solution dyed BCF yarn.

[0055] 2) Selection of composite base fabric: select polypropylene woven fabric with a weight of 95 g / ㎡ and a density of 114 warp×63 weft as the base material, lay 150 g / ㎡ polypropylene staple fiber on the base material, and then use RY1-4000 non-woven acupuncture Acupuncture is performed on the machine to form ...

Embodiment 2

[0060] This embodiment relates to a fully recyclable tufted chemical fiber carpet, such as figure 2 shown, including:

[0061] Carpet surface: including loop pile layer 5,

[0062] Base fabric layer: composed of base material layer 2 and needle-punched non-woven fabric layer 3; the bottom of needle-punched non-woven fabric layer 3 is a melted and solidified structure formed by melting and solidifying the tufted yarn roots and needle-punched non-woven fabric layer 3 layer.

[0063] The preparation of the fully recyclable tufted chemical fiber carpet comprises the steps:

[0064] 1) Yarn selection: 1800D polyester DTY network yarn is used, and the twist direction of the yarn is S twist;

Abstract

The invention discloses a tufted chemical fiber carpet capable of being completely recycled and a preparation method thereof. The carpet is composed of a carpet surface layer and a base cloth layer. The base cloth layer is a composite base cloth layer formed by a chemical fiber knitted or woven fabric and a needle-punched chemical fiber non-woven fabric; the carpet surface layer comprises a tufting layer which is formed on one side of the chemical fiber knitted or tatted fabric after tufting processing is performed on the composite base cloth layer by using chemical fiber yarns; and the roots of the chemical fiber yarns raised on the bottom surface of the base cloth layer and the needled chemical fiber non-woven fabric at the bottom of the composite base cloth layer are fused into a whole by utilizing high-temperature fusion. The tufted chemical fiber carpet capable of being completely recycled has an excellent fluff fixing effect and has an antiskid effect; other chemical substances such as adhesives and anti-skid materials are not used in the whole production process, and no pollution is generated; and the whole product can be completely recovered and then melted and granulated again, so that secondary utilization is realized, and pollution and damage to the environment are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of carpets, in particular to a fully recyclable tufted chemical fiber carpet and a preparation method thereof. Background technique [0002] Tufted carpet is the most used variety in the world, and the mainstream material is chemical fiber, but the main process of tufted chemical fiber carpet on the market is to implant the yarn made of chemical fiber into various fibers through tufting machine. Form the carpet surface on the base cloth, and then scrape adhesive or thermoplastic elastomer on the back of the blank to form a backing to achieve the effect of fixing the suede fibers, or use various adhesives to bond the yarn fibers at the bottom of the blank to the backing. The lining is bonded into a firm whole to achieve the effect of fixing the suede fibers. At present, most of the traditional techniques of tufted carpets use certain adhesives such as thermoplastic elastomers, hot melt adhesives, natural lat...
