Description

Sectional type elastic webbing

Technical Field

The utility model relates to a sectional elastic braid, and belongs to the technical field of braids.

Background

In the process of connecting two parts needing elastic buffering, an elastic braid is usually arranged to connect the two parts, so that when the two parts are closed again after being opened, a certain restoring force can be provided by the sectional elastic braid. However, conventional elastic webbing is usually woven from elastic yarns and filaments, and is elastic throughout the length of the webbing. However, when such an elastic webbing is connected to a component, elastic elongation occurs in the same manner as in the fixed position of the component when the elastic webbing is in operation, and the fixed position of the component becomes unstable due to elongation, thereby affecting the service life of the fixed position. How to improve the service life of the elastic webbing under the condition of good elastic recovery becomes a problem to be solved.

Disclosure of utility model

The utility model aims to provide a sectional elastic webbing, wherein the positions where two ends of the webbing are fixed with parts have smaller elasticity, so that the connection condition of the fixed positions is not affected when the webbing is elastically stretched.

In order to solve the technical problems, the aim of the utility model is realized as follows:

The utility model relates to a sectional elastic webbing, which comprises a first knitting area, a second knitting area and a third knitting area, wherein the first knitting area, the second knitting area and the third knitting area are formed by interweaving warp yarns and weft yarns; the warp yarns comprise a first warp yarn and a second warp yarn, and the second warp yarn has elasticity;

The first weaving area and the third weaving area are formed by interweaving first warp yarns and second warp yarns with weft yarns, and the second weaving area comprises a tubular fabric at the periphery and second warp yarns which are arranged in parallel and positioned in the tubular fabric.

The above-mentioned scheme is based on and is a preferable scheme of the above-mentioned scheme: the first warp yarn and the weft yarn are chemical fiber filaments, short fiber yarns or blended yarns.

The above-mentioned scheme is based on and is a preferable scheme of the above-mentioned scheme: the second warp yarn is an elastic yarn, a spandex filament, an elastic nylon filament or an elastic polyester filament.

The above-mentioned scheme is based on and is a preferable scheme of the above-mentioned scheme: the second warp yarns are arranged at intervals on the first warp yarns which are interwoven with the weft yarns in the first weaving region and the third weaving region; the second warp yarn is disposed parallel to the first warp yarn and simultaneously interweaves with the weft yarns.

The above-mentioned scheme is based on and is a preferable scheme of the above-mentioned scheme: the first woven area and the third woven area are interwoven in a plain weave.

The beneficial effects of the utility model are as follows: the sectional elastic webbing related by the utility model is formed by braiding the braiding areas with smaller elasticity at the two ends of the braiding area with elasticity, and the sectional elastic webbing with smaller elasticity at the two ends and larger elasticity in the middle is formed. Therefore, the two ends fixed with the parts cannot influence the fixed position due to elastic deformation of the braid, and the buffering effect is improved.

Detailed Description

The utility model will be further described with reference to the drawings and specific examples.

The present embodiment will be described in detail with reference to fig. 1 to 3. A sectional elastic webbing according to the present embodiment includes a first woven region 1, a second woven region 2, and a third woven region 3 formed by interweaving warp yarns and weft yarns; the warp yarns comprise a first warp yarn 11 and a second warp yarn 12, the second warp yarn 12 having elasticity.

The first woven area 1 and the third woven area 3 are formed by interweaving first warp yarns 11 and second warp yarns 12 with weft yarns 21, and the second area 2 comprises a peripheral tubular fabric and second warp yarns 12 which are arranged in parallel and positioned inside the tubular fabric.

The second warp yarn 12 having elasticity is in a straightened state of no elongation or a state of less elongation when the first woven region 1 and the third woven region 3 are woven, so that the first woven region 1 and the third woven region 3 are made to have less elongation. In this embodiment, a smaller elongation means an elongation of not more than 5%. The second warp yarn 12 having elasticity is in a state of being greatly elongated when the second woven region 2 is woven, and is not interwoven with the weft yarn 21 in the second woven region 2, but is merely located inside the tubular fabric, providing elasticity, and the second warp yarn 12 in the second woven region 2 is contracted in a relaxed state, thereby causing the tubular fabric to be wrinkled. The state of large elongation means that the second warp yarn 12 is in an elastically elongated state, and the elongation is at least 30% or more, and can be adjusted as required. The sectional type elastic webbing is webbing with smaller elasticity at two ends and larger elasticity in the middle.

Further, the first warp yarn 11 and the weft yarn 21 are chemical fiber filaments, staple fiber yarns or blended yarns. The color can be selected according to actual needs, and can be black, white or other colors. Specifically, in this embodiment, the first warp yarn 11 and the weft yarn 12 are selected from polyester filaments among the chemical fiber filaments, and the color is black.

Further, the second warp yarn 12 is an elastic yarn, a spandex filament, an elastic nylon filament or an elastic polyester filament. The choice of the material and the choice of the thickness of the second warp yarn 12 are chosen according to the desired elasticity. In this embodiment selected as elastic threads.

Further, in the first weaving zone 1 and the third weaving zone 3, the second warp yarns 12 are arranged at intervals on the first warp yarns 11 which are interwoven with the weft yarns 21; the second warp yarn 12 is arranged parallel to the first warp yarn 11 and simultaneously weaves with the weft yarns. The number of second warp yarns 12 is also set to take into account the elasticity required for the webbing.

Specifically, the ratio of the first warp yarn 11 to the second warp yarn 12 may be set to 2:1, or may be other ratios, such as 1:1, 3:1, 4:1, etc. The second warp yarns 12 are arranged with a spacing of one first warp yarn 11 when weaving in the first woven region 1 and the third woven region 3. The adjacent first warp yarns 11 and second warp yarns 12 arranged in parallel have the same interweaving rule and rise and fall simultaneously. And the widths of the first woven region 1, the second woven region 2, and the third woven region 3 are the same.

Further, the first woven area 1 and the third woven area 3 are interwoven in a plain weave or a twill weave. The plain weave is selected in this embodiment because the plain weave has the most interlacing points, and it is possible to better fix the elastic thread, thereby preventing the elastic thread from shrinking and moving.

The foregoing describes in detail preferred embodiments of the present utility model. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the utility model by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
