Description

Technical Field

[0001] The utility model relates to the field of fabrics, and more specifically, to an anti-static fabric. Background Art

[0002] The existing anti-static fabrics make the fabrics anti-static by coating anti-static agents on the fabric surface. However, after multiple washes, the anti-static agents will gradually disappear, thus affecting the anti-static effect of the fabrics. And due to the coverage of the auxiliaries, the air permeability of the anti-static fabrics is poor. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art, and provide an anti-static fabric. By quilting two layers of fabrics together, the contact area of the fabric is reduced on the surface fabric layer, the conductivity of the fabric is increased, the moisture absorption of the fabric is increased on the lining fabric layer, and the surface fabric layer is woven to form inclined concave and convex strips, so as to reduce the contact area of the fabric, thereby reducing the mutual acting force and the generation of friction force, reducing the generation of static electricity from a physical level, and increasing the conductivity of the surface fabric layer through the blended yarn of conductive fibers, polyester fibers and cotton fibers in the surface fabric layer. Ventilation holes are formed by weaving in the lining fabric layer, so that the hot air generated by the fabric and the human body is discharged through the ventilation holes. And because of the quilting connection between the concave area of the surface fabric layer and the lining fabric layer, the convex area of the surface fabric layer and the ventilation holes of the lining fabric layer conduct air circulation, thereby increasing the air permeability of the fabric.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model discloses an anti-static fabric, which includes a lining fabric layer and a surface fabric layer arranged in sequence from inside to outside. The surface fabric layer includes a concave area and a convex area. Both the concave area and the convex area are inclined at an angle of 15 degrees and arranged at an interval of 1:1. The surface fabric layer and the lining fabric layer are connected by quilting. The lining fabric layer includes ventilation holes, and the ventilation holes are opposite to the centers of the convex areas.

[0006] Further, the widths of both the concave area and the convex area are 0.2 cm - 0.8 cm.

[0007] Further, the quilting is located at the midline of the concave area and is inclined at the same angle as the concave area and the convex area.

[0008] Further, the height of the convex area is twice that of the concave area.

[0009] Further, the diameter of the ventilation holes is 0.1 cm - 0.5 cm. The distance between two adjacent ventilation holes in the width direction is the width of one concave area, and the distance between two adjacent ventilation holes in the longitudinal direction is the width of three concave areas.

[0010] Further, the surface fabric layer has a cycle of 8 rows of loops. The raised areas are formed by knitting the 3rd and 4th lower needles of the 1st, 3rd, 6th, and 8th rows of loops, and the 1st and 2nd lower needles of the 2nd, 4th, 5th, and 7th rows of loops. The sunken areas are formed by knitting the 1st and 3rd upper needles of the 1st, 5th, and 7th rows of loops, and the 2nd and 4th upper needles of the 3rd row of loops.

[0011] Further, the lining fabric layer has a cycle of 24 rows of loops. The ventilation holes are formed by knitting the 2nd and 4th lower needles together in the 2nd row of loops and the 1st and 3rd lower needles together in the 4th row of loops.

[0012] Further, for the lower needles of the 1st - 8th rows of loops of the surface fabric layer, 50D - 170D conductive fiber and polyester fiber are knitted into loops, and for the upper needles of the 1st - 8th rows of loops of the surface fabric layer, 50D - 170D conductive fiber and cotton fiber are knitted into loops.

[0013] Further, for all the 1st - 24 rows of loops of the lining fabric layer, 50 - 120 English cotton yarn is knitted into loops.

[0014] Further, the horizontal density of the surface fabric layer is 120 - 140 counts per inch, the vertical density of the surface fabric layer is 84 - 96 counts per inch, the horizontal density of the lining fabric layer is 106 - 132 counts per inch, and the vertical density of the lining fabric layer is 76 - 90 counts per inch.

[0015] The beneficial effects of the present utility model are as follows:

[0016] The surface fabric layer and the lining fabric layer are formed by quilting connection. The surface fabric layer forms concave - convex and inclined strips by reducing the contact area of the fabric, thereby reducing friction. The conductivity of the fabric is increased by the blended spinning of conductive fiber with polyester fiber and cotton fiber. The lining fabric layer increases the hygroscopicity of the fabric by knitting with cotton fiber, thereby reducing static electricity generation. The hot air is discharged through the ventilation holes, and the air circulation is formed by the non - connection between the raised areas of the surface fabric layer and the ventilation holes of the lining fabric layer, thereby increasing the air permeability of the fabric.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figure 1 shown in FIG. 4, an anti-static fabric includes a lining fabric layer 200 and a surface fabric layer 100 arranged in sequence from the inside out. The surface fabric layer 100 includes a sunken area 101 and a raised area 102. The widths of both the sunken area 101 and the raised area 102 are 0.2 cm - 0.8 cm. Preferably, the widths of both the sunken area 101 and the raised area 102 are 0.5 cm. And both the sunken area 101 and the raised area 102 are inclined at an angle of 15 degrees and arranged at an interval of 1:1. The diagonal distribution enables the fabric to have better elasticity. The diagonal distribution of the sunken area 101 can increase the contact area of the fabric, and can better form conductivity. The diagonal distribution of the raised area 102 can increase the air circulation area of the fabric, thereby increasing the breathability of the fabric.

[0025] The surface fabric layer 100 is woven to form inclined concave-convex stripes, which are formed by weaving in a cycle of 8 rows of loops. Each row of loop columns includes 4 knitting needles for purl stitches and 4 knitting needles for plain stitches. In the 1st, 3rd, 6th, and 8th rows of loop columns, the 1st and 2nd purl stitches do not knit, the 3rd and 4th purl stitches knit to form loops. In the 2nd, 4th, 5th, and 7th rows of loop columns, the 1st and 2nd purl stitches knit to form loops, and the 3rd and 4th purl stitches do not knit, thus forming the raised area 102. In the 1st, 5th, and 7th rows of loop columns, the 1st and 3rd plain stitches knit to form loops, the 2nd and 4th plain stitches do not knit. In the 3rd row of loop columns, the 2nd and 4th plain stitches knit to form loops, the 1st and 3rd plain stitches do not knit. In the 2nd, 4th, 6th, and 8th rows of loop columns, all the plain stitches do not knit, thus forming the sunken area 101. The height of the woven raised area 102 is twice that of the sunken area 101, so that a height difference is formed between the raised area 102 and the sunken area 101. Since the sunken area 101 is sewn to the lining layer 200 and the raised area 102 is higher than the sunken area 101, the raised area 102 is not sewn to the lining layer 200, thereby reducing the contact area between the raised area 102 and the lining layer 200. At the same time, the area of the sunken area 101 adsorbing external air and dust is reduced, so as to reduce the interaction force between fibers, thereby reducing the friction between fabrics and reducing the generation of static electricity from a physical level.

[0026] The surface fabric layer 100 is woven from a blended yarn of conductive fibers, polyester fibers, and cotton fibers. The purl stitches in the 1st - 8th rows of loop columns of the surface fabric layer 100 are knitted into loops with 50D - 170D conductive fibers and polyester fibers. Preferably, the purl stitches in the 1st - 8th rows of loop columns of the surface fabric layer 100 are knitted into loops with 100D conductive fibers and polyester fibers. The plain stitches in the 1st - 8th rows of loop columns of the surface fabric layer 100 are knitted into loops with 50D - 170D conductive fibers and cotton fibers. Preferably, the plain stitches in the 1st - 8th rows of loop columns of the surface fabric layer 100 are knitted into loops with 100D conductive fibers and cotton fibers. Therefore, the conductive fibers and polyester fibers are woven to form the raised area 102, increasing the conductivity of the surface fabric layer 100. The conductive fibers and cotton fibers form the sunken area 101, which not only increases the conductivity of the surface fabric layer 100, but also increases the moisture absorption of the sunken area 101 because the conditioned regain of cotton fibers is 8.5%, while reducing the adsorption of external dust, thus reducing the generation of static electricity. The water molecules absorbed by the cotton fibers will also carry away part of the static electricity.

[0027] The lining layer 200 includes ventilation holes 201. The lining layer 200 has a cycle of 24 course wales. The 2nd and 4th lower needle stitches of the 2nd course wale and the 1st and 3rd lower needle stitches of the 4th course wale are knitted to form the ventilation holes 201. The diameter of the ventilation holes 201 is 0.1 cm - 0.5 cm. Preferably, the diameter of the ventilation holes 201 is 0.28 cm. The distance between two adjacent ventilation holes 201 in the width direction is the width of a recessed area 101, and the distance between two adjacent ventilation holes 201 in the longitudinal direction is three times the width of the recessed area 101. Also, the ventilation holes 201 are centered relative to the raised area 102. Since there is a height difference between the raised area 102 and the recessed area, and the ventilation holes 201 are located directly below the center of the raised area 102, an air circulation area is formed between the ventilation holes 201 and the raised area 102. The hot air generated by the human body is led out through the ventilation holes 201 to the space between the ventilation holes 201 and the raised area 102, and then is led out to the outside through the yarn gaps between the raised areas 102, thereby increasing the breathability of the fabric.

[0028] The 1st - 24th course wales of the lining layer 200 are all knitted with cotton fibers of 50 - 120 English counts. Preferably, the 1st - 24th course wales are all knitted with cotton fibers of 75 English counts. Since all 24 course wales of the lining layer 200 are made of cotton fibers, and the conditioned regain of cotton fibers is 8.5%, the lining layer 200 has good hygroscopicity. Therefore, the cotton fibers will absorb the gases and liquids generated by the human body, thereby removing the static electricity generated during the friction between the fabric and the human body, and thus reducing the static electricity of the fabric.

[0029] The face fabric layer 100 and the lining layer 200 are connected by quilting 110, and the quilting 110 is located at the mid - line of the recessed area 101 and is inclined at the same angle as the recessed area 101 and the raised area 102. Therefore, air circulation can be formed between the raised area 102 and the ventilation holes 201. By connecting at the mid - line position of the recessed area 101 through the quilting 110, the face fabric layer 100 and the lining layer 200 can be relatively fixed. The horizontal density of the face fabric layer 100 is 120 - 140 stitches per inch, the vertical density of the face fabric layer 100 is 84 - 96 stitches per inch, the horizontal density of the lining layer 200 is 106 - 132 stitches per inch, and the vertical density of the lining layer 200 is 76 - 90 stitches per inch. Therefore, through the connection of the quilting 110, the stitches at the mid - line position of the recessed area 101 can be fixed to the lining layer 200, thereby fixing the two - layer fabric. Also, the two sides of the quilting 110 are not connected. Therefore, in addition to the air circulation formed between the raised area 102 and the ventilation holes 201, weak air exchange can occur on both sides of the quilting 110, thereby increasing the breathability of the fabric and increasing the hygroscopicity at the connection of the two layers, thus reducing the presence of static electricity in the fabric.

[0030] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
