Abstract

The invention belongs to the technical field of textiles and particularly relates to warp and weft forwards and backwards entwisted white body obliquely-interwoven fabric. The white body obliquely-interwoven fabric is formed by tailoring and shaping plain fabric which is formed by weaving warp and weft. The warp and the weft are perpendicular to each other and the warp and a fabric side form an included angle of 45 degrees. The warp is composed of forwards entwisted yarn which is formed by twisting at least two strands of raw material yarn and backwards entwisted yarn which is formed by twisting at least two strands of the raw material yarn. The weft is composed of forwards entwisted yarn which is formed by twisting at least two strands of raw material yarn and backwards entwisted yarn which is formed by twisting at least two strands of the raw material yarn. The warp is arranged at intervals in a forwards entwisted mode and a backwards entwisted mode. The weft is arranged at intervals in a forwards entwisted mode and a backwards entwisted mode. The breaking strength of the warp and weft forwards and backwards entwisted white body obliquely-interwoven fabric is 30%-50% that of conventional woven fabric and the elongation at break of the warp and weft forwards and backwards entwisted white body obliquely-interwoven fabric is 2.5 to 4 times that of the conventional woven fabric. The warp and the weft are arranged at intervals in the forwards entwisted mode and the backwards entwisted mode to be woven and the fabric is more compact, higher in strength, not prone to deformation when being used, free of off tracking and long in service life.

Description

The positive reverse lay openpore of graticule oblique cloth

Technical field:

The invention belongs to textile technology field, refer in particular to the positive reverse lay openpore of a kind of graticule oblique cloth.

Background technology:

Oblique cloth refer to warp thread and weft yarn orthogonal, and warp thread and selvedge are the woven fabric of 45 ° of angles.This fabric has overcome the oblique strong hypodynamic shortcoming of traditional woven thing, smooth, docile during with taper or the object with arc in looping, thereby can meet the specific (special) requirements of looping fabric, both can be used as space flight, some winding fabrics cylindrical, taper device of national defense industry, also can be used as automobile cord fabric etc.

Summary of the invention:

The object of this invention is to provide the positive reverse lay openpore of high, the on-deformable graticule of a kind of intensity oblique cloth.

The present invention is achieved in that

The positive reverse lay openpore of graticule oblique cloth, weave by warp and parallel the plain cloth forming and cut out the openpore oblique cloth that shaping forms, described warp is mutually vertical with parallel, and warp and selvedge are 45 ° of angles, described warp is twisted the positive twist yarn forming and twisted by two strands of above raw material threads the reverse lay yarn forming by two strands of above raw material threads, described parallel is twisted the positive twist yarn forming and twisted by two strands of above raw material threads the reverse lay yarn forming by two strands of above raw material threads, described warp is according to just twisting with the fingers, reverse lay is spaced, described parallel is according to just twisting with the fingers, reverse lay is spaced.

Above-mentioned raw material thread is long filament or short fiber or blending, described long filament is chinlon filament or polyester filament or aramid filament or polyvinyl long filament, described short fiber is aramid fiber short fiber or terylene short fiber or polyvinyl short fiber or terylene short fiber or textile silk or pure fiber crops, and described blending is terylene, cotton blending or polyamide fibre, cotton blending or aramid fiber, cotton blending or cotton, numb blending.

The twist of above-mentioned long filament is that twist with the fingers 8 sth. made by twisting-560.

The twist of above-mentioned short fiber is that twist with the fingers 45 sth. made by twisting-520.

In above-mentioned terylene, cotton blending, terylene and cotton percentage composition are: 95%-5%:5%-95%, polyamide fibre in described polyamide fibre, cotton blending and cotton percentage composition are: 95%-5%:5%-95%, aramid fiber in described aramid fiber, cotton blending and cotton percentage composition are: 95%-5%:5%-95%,, percentage composition cotton and numb in described cotton, numb blending is: 95%-5%:5%-95%.

The advantage that the present invention gives prominence to is compared to existing technology:

1, ultimate strength of the present invention is 30%～50% of conventional woven fabric, and elongation at break is 2.5～4.0 times of conventional woven fabric;

2, warp of the present invention and parallel just twisting with the fingers, reverse lay is spaced and weaves, fabric is tightr, intensity is higher, uses not yielding, sideslip not, long service life.

Accompanying drawing explanation:

Fig. 1 is structural representation sketch of the present invention.

In figure: 1, warp; 2, parallel; 3, selvedge; α: angle.

The specific embodiment:

With specific embodiment, the invention will be further described below, referring to Fig. 1:

The positive reverse lay openpore of graticule oblique cloth, the plain cloth being woven by warp 1 and parallel 2 is cut out the openpore oblique cloth that shaping forms, described warp 1 is mutually vertical with parallel 2, and warp 1 is 45 ° of angle α with selvedge 3, described warp 1 is twisted the positive twist yarn forming and twisted by two strands of above raw material threads the reverse lay yarn forming by two strands of above raw material threads, described parallel 2 is twisted the positive twist yarn forming and twisted by two strands of above raw material threads the reverse lay yarn forming by two strands of above raw material threads, described warp 1 is according to just twisting with the fingers, reverse lay is spaced, described parallel 2 is according to just twisting with the fingers, reverse lay is spaced.

The content of above-mentioned various blending can adopt 20%:80% than row; 30%:70%; 65%:35%; 50%:50%; 80%:20%; 70%:30%; 35%:65% etc.

Above-described embodiment is only one of preferred embodiment of the present invention, not limits practical range of the present invention with this, therefore: all equivalences of doing according to shape of the present invention, structure, principle change, within all should being covered by protection scope of the present invention.
