The invention provides an antistatic fabric, which comprises: the anti-static polyester yarn comprises a bottom yarn and a surface yarn, wherein the bottom yarn comprises an anti-static yarn and polyester, the anti-static yarn and the polyester are in warp knitting structures, the thickness of the anti-static yarn is 150D, and the surface yarn is flat polyester yarn of 150D/288F or 120D/192F. The antistatic yarn comprises 50S acrylic modified yarn and 50D polyester filament yarn and is of a double-spiral structure. The spacing of the antistatic yarn in the ground yarn was 3.5 cm. When the antistatic fabric is rubbed with fabrics or objects (such as pure cotton, pure polyester, nylon, wool, silk and the like) made of different materials, static electricity can be effectively prevented; the antistatic conductive short fibers on the contact surface of the antistatic fabric and the human body can quickly conduct static electricity generated by the human body, cut off current and protect the safety of the human body and the surrounding environment; each antistatic yarn can be used as an independent antistatic material, and the antistatic effect cannot be lost due to the damage of the fabric.

Description

Antistatic fabric

Technical Field

The invention relates to the field of textiles, in particular to an antistatic fabric.

Background

At present, 120D or less yarns are generally adopted as antistatic yarns in the conventional method, 2.5CM yarns are adopted at intervals to be woven at the bottom of the fabric, and the materials generally adopt metal or conductive polyester and the like as conductive carriers, but the following problems exist: 1. the antistatic polyester fabric can produce a good antistatic effect only when being rubbed with pure polyester fabrics, but can not achieve a good conductive effect when being rubbed with other material fibers such as pure cotton, wool and silk. 2. Under the present scheme condition, even the unable small hole that perceives of naked eye appears in surface fabric in use, perhaps in the surface fabric bottom, appears the damage, can cause the fracture of antistatic yarn, causes the incompleteness of its structure, because of the present scheme is as antistatic principle with the conduction to can influence the holistic antistatic effect of surface fabric.

Disclosure of Invention

The invention provides an antistatic fabric which can effectively prevent static electricity from being generated and does not influence the overall antistatic effect of the fabric after the fabric is damaged.

The technical scheme of the invention is realized as follows:

antistatic surface fabric includes: bottom yarn and table yarn, the bottom yarn includes antistatic yarn and dacron, antistatic yarn and dacron are the warp knitting structure, the antistatic yarn thickness is 150D, the table yarn is flat dacron silk.

Further, the antistatic yarn comprises 50S acrylic acid modified yarn and 50D polyester filament yarn, wherein the 50S acrylic acid modified yarn and the 50D polyester filament yarn are of double-spiral structures.

Further, the spacing of the antistatic yarns in the ground yarns was 3.5 cm.

Further, the surface yarn is 150D/288F or 120D/192F flat polyester yarn.

Further, the thickness of the bottom yarn is 1-2 mm, and the thickness of the surface yarn is 9-10 mm.

Further, the gram weight of the antistatic fabric is 180-380 g/m²。

The invention has the beneficial effects that:

(1) compared with the existing conductive antistatic fabric, the antistatic fabric can effectively prevent static electricity from being generated when the antistatic fabric is rubbed with fabrics or objects (such as pure cotton, pure polyester, nylon, wool, silk and the like) made of different materials; the antistatic conductive short fibers on the contact surface of the antistatic fabric and the human body can quickly conduct static electricity generated by the human body, cut off current and protect the safety of the human body and the surrounding environment; each antistatic yarn can be used as an independent antistatic material, and the antistatic effect cannot be lost due to the damage of the fabric.

(2) The acrylic acid modified fiber adopted by the antistatic fabric has high moisture regain, so that the fabric can store certain moisture and play a role in moisturizing in winter.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.

FIG. 1 is a schematic structural diagram of an antistatic fabric of the present invention;

FIG. 2 is a schematic illustration of a ground yarn warp knit construction of the present invention;

fig. 3 is a schematic representation of the structure of an antistatic yarn of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The antistatic fabric, as shown in fig. 1, comprises: bottom yarn 1 and table yarn 2, bottom yarn 1 includes dacron 10, antistatic yarn 11, and antistatic yarn 11 and dacron are 10 warp knitting structures, and table yarn 2 is flat dacron silk, and antistatic yarn thickness is 150D.

Specifically, as shown in fig. 2, the antistatic yarn 11 includes a 50S acrylic modified yarn 101 and a 50D polyester filament 102, and the 50S acrylic modified yarn 101 and the 50D polyester filament 102 have a double spiral structure.

The 50S acrylic modified yarn 101 is formed by spinning acrylic modified fiber with the molecular formula of

Therefore, the acrylic modified fiber is coated with a layer of hydrophilic group, so that the acrylic modified fiber is easy to absorb environmental moisture, on one hand, the fabric can store certain moisture, has high moisture regain and can play a moisture-preserving role in winter; on the other hand, the static electricity can be quickly leaked to achieve the antistatic purpose by combining hydrogen bonds with moisture in the air to form a monomolecular conducting layer.

Further, the spacing of the antistatic yarn in the ground yarn was 3.5 cm. Therefore, the antistatic yarns can be uniformly distributed in the bottom yarns of the fabric and exert the antistatic property. When the antistatic agent is rubbed with fabrics or objects (such as pure cotton, pure polyester, nylon, wool, silk and the like) made of different materials, the antistatic agent can effectively prevent static electricity from being generated. The antistatic test data are shown in the following table:

the preferred surface yarn is 150D/288F or 120D/192F flat polyester yarn.

Furthermore, the thickness of the bottom yarn is 1-2 mm, and the thickness of the surface yarn is 9-10 mm. The bottom yarn and the surface yarn are matched to have antistatic property on one hand, and the fabric has certain softness and thickness on the other hand.

Furthermore, the gram weight of the antistatic fabric is 180-380 g/m²，

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
