Abstract

A welting carpet comprises a carpet and welting cloth, wherein the welting cloth is arranged on the carpet in an L-shaped welting mode through an adhesive film thermally closed on the welting cloth. This carpet just can reach fine welt fixed pile effect at the position cloth pasting on carpet limit, need not to set up the pretreatment process and carry out special treatment, consequently, does not have high expectations to woven carpets such as tufting, and application scope is wide, has practiced thrift the loaded down with trivial details process of traditional carpet welt greatly, reduces the waste of manual work and material, environmental protection more.

Description

Welting carpet

Technical Field

The utility model relates to a textile sector especially relates to a machine knits tufting welt carpet.

Background

Currently, woven carpets and hand carpets are the main in the carpet industry. Tufted carpet and Wilton carpet in the woven carpet and gun-punched carpet in the hand carpet are woven carpets which are formed by mechanically tufting or interweaving warp yarns, weft yarns and pile yarns on a chemical fiber fabric backing fabric to form a cut pile carpet surface. The back of the base cloth of the carpet is coated with resin and sizing material (backing sizing material) to fix looped pile or plush, so as to prevent the fluffy from loosening and falling off and improve the dimensional stability of the carpet. The back of the carpet coated with the glue can be adhered with a layer of foam backing, the back of the carpet is adhered with a layer of TPE to enhance the service performance of the carpet, and the back of the carpet is adhered with a second layer of fabric called secondary backing, which has the functions of increasing the elasticity and durability of the tufted carpet. The carpet with the secondary backing is cut into required size according to customer requirements, and then the falling of fluff at the edge part is processed in the modes of overlocking, edge covering and edge attaching.

The woven carpet has the phenomenon that pile drops at the cutting position after being cut, and the pile cannot be completely fixed on the carpet by glue used in the processing procedure. At present, most carpets adopt the modes of overlocking, edge covering and welting to treat the phenomenon of pile shedding at the edge. The existing welting processing method is to use styrene-butadiene rubber and natural latex as adhesives to be manually pasted on a carpet, and the process has low efficiency, poor gluing fastness, easy yellowing of welting parts, no environmental protection and uncontrollable product stability.

Therefore, effective innovation of the prior art is needed to address the above drawbacks.

Disclosure of Invention

The utility model aims to provide a welt carpet, this welt carpet simple structure, easily automated production, the material is few, has reduced the waste of material to laminating fastness is strong, and product quality is stable controllable.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a welting carpet comprises a carpet and welting cloth, wherein the welting cloth is arranged on the carpet in an L-shaped welting mode through an adhesive film thermally bonded on the welting cloth;

correspondingly, the adhesive film comprises a TPU adhesive film;

correspondingly, the adhesive film and the edge-pasting cloth have the same length and width, and are aligned and heated together;

correspondingly, the carpet comprises a first base cloth, a second base cloth, viscose and tufting, wherein the first base cloth and the second base cloth are fixedly bonded through the viscose, and the tufting is arranged on the first base cloth.

The utility model has the advantages that: the utility model discloses only can reach fine fixed pile effect of welt at the position cloth pasting on carpet limit, need not to set up the pretreatment process and carry out special treatment, consequently, it is not high to weave carpet requirements such as tufting, and application scope is wide, has practiced thrift the loaded down with trivial details process of traditional carpet welt greatly, reduces the waste of manual work and material, environmental protection more.

Detailed Description

As shown in fig. 1, in an embodiment of the present invention, the welt carpet includes a carpet 3 and a welt cloth 1, wherein the carpet 3 includes a first base cloth 31, a second base cloth 32, an adhesive 33 and a tufting 34, the first base cloth 31 and the second base cloth 32 are bonded and fixed by the adhesive 33, the tufting 34 is disposed on the first base cloth 31, the welt cloth 1 is disposed on the carpet 3 in an "L" shape through a TPU adhesive film 2, that is, a part of the welt cloth 1 is thermally sealed on the second base cloth 31, and another part is bonded on the tufting 34.

As shown in fig. 2-4, to obtain a welted carpet according to an embodiment, a welting process is used that includes the steps of:

1) preparing a tufted carpet, the tufts 34 having a height of 12 mm;

2) preparing a polyester non-woven fabric which has the same length as the tufted carpet and the width of 40mm as welt cloth 1;

3) preparing a TPU glue film 2 with the same length as the tufted carpet and the width of 40 mm;

4) setting parameters of a heat sealing machine 4: the temperature is set to be 120-;

5) the edge attaching cloth 1 and the TPU adhesive film 2 are subjected to limiting alignment and then enter a heat sealing machine 4 to be heated together;

6) adjusting the welting machine 5, setting the temperature to be 170-190 ℃, setting the pressure of the compression roller to be 0.6-0.7Mpa, setting the conveying speed of the welting machine 5 to be 4m/min, and adjusting the hem height of a hem tap on the welting machine 5 to be 5-6 mm;

7) the side of the edge sticking cloth 1 with the TPU glue film 2 is placed upwards and then passes through the edge folding faucet. The tufts 34 are placed on the production line with the carpet facing upwards, and the press roll activating device is lowered to feed the tufts 34 together with the welt 1 to the press roll for heat bonding.
