Abstract

Elastic webbing is woven through a double-weft needle and a double-layer belt. A rubber thread (301) is placed between a first belt layer (101) formed by a first weft of the elastic webbing and a second belt layer (201) formed by a second weft, which increases integral elasticity and restoring force of the elastic webbing, increases smoothness and stability of an integral surface of the elastic webbing, avoids a phenomenon where the rubber thread is exposed outside due to strong stretching of the elastic webbing and makes the elastic webbing to be hardly aging and retain high elasticity in a long term. The elastic webbing applies to a shoulder belt of a portable shoulder bag or a backpack, or a hand belt. Favorable expansion force thereof can obviously relieve pressure on a shoulder of a bag backpack user. The elastic webbing has characteristics of high elasticity and low probability of aging. Therefore a service life of the backpack shoulder belt is prolonged.

Description

Elastic webbing and weaving method thereof

This invention relates to textile technology, and more particularly to an elastic webbing and a method of weaving the same.

Background technique

At present, for the luggage industry, the shoulder straps of the bags are made of traditional materials, and the traditional materials are generally composed of main cloth, sponge, elastic cloth, ordinary ribbon and the like. Due to the lack of physical reaction function of traditional materials, the shoulder strap can not significantly reduce the load. For those who often use shoulder bags or backpacks, when the shoulder bag or backpack is loaded with heavier objects, it is very fast. Will make the user's shoulders sore.

In order to solve the above technical problems, some designers add an air cushion or a sponge pad inside the shoulder strap, but the effect on reducing the load is not obvious. In addition, some designers add an elastic webbing to the top of the backpack to reduce the load on the backpack.

The second rubber yarn 134, the third rubber yarn 135, the fourth rubber yarn 208, and the fifth rubber yarn 209 disposed on both sides of the plurality of sets of warp yarns further stabilize the structure of the elastic webbing, and further make the elastic webbing more Beautiful mouth.

Optionally, the second rubber filament 134, the third rubber filament 135, the fourth rubber filament 208 and the fifth rubber filament 209 are circular rubber filaments having a diameter of 0.7 to 1.2 mm.

The elastic webbing provided by the embodiment is manufactured by a double-layered high-weft weft technique, and the weft density of the two weft surfaces is 17 to 22 latitude/cm, so that the surface of the elastic webbing is smooth, and the elastic webbing and other objects are reduced. Rubbing to reduce wear. Since the elastic webbing is not easily exposed when stretched, it can reduce the erosion of external gas or liquid, avoid accelerated aging, and thereby improve the life. In addition, the rubber thread of the elastic webbing is tightly sandwiched between the first belt layer and the second belt layer, and the structure is stable, especially when the first rubber yarn is selected from a circular shape having a diameter of 1.0 to 1.2 mm. When the rubber yarn is used, the tensile strength and the shrinkage speed are further improved.

In order to more clearly illustrate the surface structure of the elastic webbing provided by the embodiment of the present invention, the following description will be made with reference to Figs. 4, 4a, 5 and 5a. Figure 4 is a cross-sectional view showing an elastic webbing of the present invention, wherein a plurality of first rubber filaments 403 are interposed between the first belt layer 401 and the second belt layer 402, and the plurality of rubber yarns 403 are Form the middle layer. The edge area A in Fig. 4 shows the edge structure of the elastic webbing, and an enlarged view of the edge area A is shown in Fig. 4a. As can be seen from FIG. 4a, the plurality of first rubber filaments 403 interposed between the first belt layer 401 and the second belt layer 402 are closely arranged, and a second rubber yarn for the edge is provided at the edge of the elastic webbing. The 404 and third rubber filaments 405, the second rubber filament 404 and the third rubber filament 405 have a smaller diameter than the first rubber filament 403. Fig. 5 is a plan view showing an elastic webbing of the present invention. From Fig. 5, the surface texture of the elastic webbing can be seen. Fig. 6a is an enlarged view of the surface area B of Fig. 5. As can be seen from Fig. 6a, the surface of the elastic webbing has three kinds of lines, which are a first line 501, a second line 502 and a third line 503, respectively. Wherein, the first grain 501 is interwoven by the warp yarn and the weft yarn disposed between the first warp yarn and the second warp yarn, and the second grain 502 is formed by interlacing the first warp yarn and the second warp yarn with the weft yarn, and the third grain path 503 It is made up of a rubber yarn and a weft yarn for the edge.

In order to better illustrate the superior performance of the elastic webbing provided by the embodiments of the present invention, the inventors use the same materials to prepare two kinds of elastic webbings, one is the elastic webbing provided by the embodiment of the present invention, and the other is the traditional twill weave method. The woven elastic webbing was tested and compared. After 48 hours, 172,800 jump jumps with a jump height of 4.2 cm were measured, and the traditional twill weave was measured flat. The elastic webbing has a static elongation of 3.8%, and the flat web has a static elongation of 1.2%, and the sling weight is 8Kg. The elongation of the elastic webbing of the conventional twill weave is 42%. The sling weight 8 Kg measure The elongation of the elastic webbing provided by the embodiment of the present invention is 13%. It can be found from the test results that the elastic webbing provided by the embodiments of the present invention can maintain long-lasting tensile properties and good elasticity, and has a long service life.

The invention also provides a method for manufacturing an elastic webbing, the manufacturing method comprising:

When the first weft surface and the second weft surface are formed by double weft knitting, a rubber yarn is placed between the weft yarn for weaving the first weft surface and the weft yarn of the second weft surface, and Using the middle frame, the warp yarns are respectively interwoven with the weft yarns of the first weft surface and the weft yarns of the second weft surface, so that the first weft surface and the second weft surface are closely coupled, and the rubber yarn is Wrapped inside the elastic webbing;

Preferably, the weft density of the first weft surface is greater than or equal to 21 latitude/cm, and the weft density of the second weft surface is greater than or equal to 21 latitude/cm. The higher the weft density of the first weft surface and the second weft surface, the smoother the surface of the woven elastic webbing and the lower the elastic properties of the elastic webbing.

It should be noted that in the weaving industry, the conventional selection by those skilled in the art according to the woven ribbon structure generally uses 8 to 12 middle frames to divide the yarn and organize the texture, and in the ordinary webbing production process, the webbing machine The ribbon machine that does not contain 14 middle frames and 14 middle frames needs to be customized.
