Description

Technical Field

[0001] This utility model relates to the field of textile technology, and more specifically, to an antistatic polyester fabric. Background Technology

[0002] Polyester fabric is a type of fabric woven from polyester fibers. Polyester fibers have high strength and abrasion resistance, making the resulting polyester fabric strong, durable, wrinkle-resistant, and easy to care for. It is widely used in the production of clothing, outdoor products, home decorations, and other products.

[0003] However, polyester fibers have relatively poor moisture absorption, which makes polyester fabrics usually quite dry. During daily wear, the fabric will continuously rub against the skin. As the fabric rubs against the skin in a dry environment, static electricity is easily generated. Due to the insulation properties of polyester fibers and the lack of sufficient moisture to help transfer the charge, the generated static electricity cannot be discharged and dispersed in time, but accumulates on the fabric, which can easily irritate the skin and affect the comfort of wearing it.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an antistatic polyester fabric, which improves the antistatic effect of polyester fabric through a new structural design.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an antistatic polyester fabric, comprising an inner layer and an outer layer, wherein the inner layer is provided with a conductive mesh on the side away from the outer layer, the outer layer includes a plurality of conductive parts and a plurality of breathable parts arranged alternately along its length, a plurality of conductive strips and a plurality of diverging strips are respectively provided on both sides of the conductive parts, the inner layer and the outer layer are supported by the plurality of conductive strips to form a plurality of ventilation cavities, the inner layer is provided with a plurality of ventilation holes communicating with the ventilation cavities, and the breathable parts are provided with a plurality of ventilation holes communicating with the ventilation cavities.

[0007] The present invention is further configured such that: a plurality of conductive meshes are composed of a plurality of horizontal bars and a plurality of vertical bars that intersect perpendicularly, and a plurality of the ventilation hole arrays are arranged between the plurality of horizontal bars and the plurality of vertical bars.

[0008] The present invention is further configured such that: the conductive strip and the diverging strip are symmetrically arranged on both sides of the conductive part, the length and width of the horizontal strip are the same as the length and width of the vertical strip, and the vertical strip is symmetrically arranged directly below the conductive strip.

[0009] The present invention is further configured such that: the inner layer is configured as a single-sided jacquard structure, the jacquard yarn of the inner layer is configured as a conductive yarn, and the ground structure of the inner layer is woven with moisture-absorbing yarn.

[0010] The present invention is further configured such that: the moisture-absorbing yarn is formed by twisting multiple strands of first strand, and the first strand is formed by twisting modified polyester profiled fibers.

[0011] The present invention is further configured such that: the outer layer is made by alternating weaving of conductive yarn with rib and loop transfer weave, the conductive yarn is made by spirally winding a second strand around a first strand, and the second strand is made by twisting silver fibers.

[0012] In summary, this invention has the following beneficial effects: The introduction of hydrophilic groups and the modified polyester shaped fibers formed after shaping improve moisture absorption, allowing the inner layer to absorb moisture from the skin or surrounding air during wear and maintain a certain level of humidity, forming a water film on the surface, thereby reducing the resistance of the inner layer. The conductive mesh reduces the contact friction area between the inner layer and the skin, thus reducing the generation and accumulation of static electricity. The silver fiber has good conductivity, allowing the outer layer to absorb static electricity from the inner layer and release it into the water molecules of the outside air. Several diverging strips increase the contact area between the outer layer and the outside air, thereby accelerating the release of static electricity. Several interconnected ventilation cavities, vents, and air holes improve airflow within and around the fabric, allowing the flowing air to continuously remove static electricity from the fabric, further enhancing the antistatic effect.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example: An antistatic polyester fabric, such as Figures 1-5 As shown, it includes an inner layer 1 and an outer layer 2 that are fixedly connected to each other. A conductive mesh 3 is provided on the side of the inner layer 1 away from the outer layer 2. The inner layer 1 is set with a single-sided jacquard structure. The ground structure of the inner layer 1 is woven with moisture-absorbing yarn 10. The jacquard yarn of the inner layer 1 is set with conductive yarn 9. The inner layer 1 is woven with moisture-absorbing yarn 10 in plain knit. The conductive mesh 3 is formed by jacquard on the basis of plain knit by conductive yarn 9. The conductive mesh 3 is composed of several horizontal strips 301 and several vertical strips 302 that intersect perpendicularly. The several horizontal strips 301 and several vertical strips 302 reduce the contact friction area between the inner layer 1 and the skin when worn, thereby reducing the generation of static electricity.

[0021] like Figure 1 and Figure 5 As shown, the moisture-absorbing yarn 10 is formed by twisting three strands of the first strand 11 using a twisting machine. The first strand 11 is formed by twisting modified polyester profiled fibers. The modified polyester profiled fibers have a cross-shaped cross section. The modified polyester profiled fibers are spun from polyester raw materials with added hydrophilic groups through a spinneret with cross-shaped openings. The hydrophilic groups are set as sulfonic acid groups. By introducing hydrophilic groups, the moisture absorption performance of polyester fibers can be effectively improved. By modifying the polyester fibers, the internal porosity and surface area of ​​the fibers are increased, further enhancing the moisture absorption effect. This allows the inner layer 1 made of modified polyester profiled fibers to absorb moisture from the skin or surrounding air and maintain a certain humidity when worn, forming a water film on the surface of the inner layer 1. Water has a high conductivity and can be used as a medium for static electricity transfer, which reduces the resistivity of the inner layer 1 surface, thereby accelerating the dissipation of static electricity and reducing the accumulation of static electricity.

[0022] like Figure 1 and Figure 3As shown, the outer layer 2 includes several conductive parts 201 and several breathable parts 202 arranged alternately along its length. A conductive strip 4 is provided on the side of the conductive part 201 near the inner layer 1, and a diverging strip 5 is provided on the side of the conductive part 201 away from the inner layer 1. Several breathable holes 8 are provided in the breathable parts 202. The outer layer 2 is made by feeding conductive yarn 9 into a knitting machine and knitting it alternately with rib and transfer knitting. The conductive parts 201 and the conductive strips 4 and diverging strips 5 on both sides are integrally formed on the outer layer 2 by rib knitting. The breathable parts 202 and the several breathable holes 8 are integrally formed on the outer layer 2 by transfer knitting. The several breathable holes 8 enable the outer layer 2 to achieve good air permeability. The rib knitting adopts the same continuous number of positive and negative loops, which is arranged so that the conductive strips 4 and diverging strips 5 are symmetrically arranged on both sides of the conductive part 201. The inner layer 1 and the outer layer 2 are supported by several conductive strips 4 to form several ventilation cavities 6.

[0023] like Figures 1-3 As shown, the length and width of the horizontal strip 301 are the same as the length and width of the vertical strip 302. The vertical strip 302 is symmetrically arranged directly below the conductive strip 4. The inner layer 1 has several ventilation holes 7 drilled by a laser punch. The horizontal strips 301 and vertical strips 302, formed by jacquard yarn weaving, can reinforce the area around the ventilation holes 7. At the same time, the high temperature generated during laser cutting can seal the inner wall of the ventilation holes 7, thus maintaining the structural stability and preventing loosening after the ventilation holes 7 are cut. The array of ventilation holes 7 is arranged between the horizontal strips 301 and the vertical strips 302, so that the ventilation holes 8 are interconnected with the ventilation cavities 6. The interconnected ventilation cavities 6, ventilation holes 7, and ventilation holes 8 improve the air circulation effect inside and on both sides of the fabric. The static electricity generated on the fabric can be released into the water molecules in the surrounding air. The flowing air can continuously carry away the static electricity on the fabric, thereby improving the antistatic effect of the fabric.

[0024] like Figures 1-4 As shown, the conductive yarn 9 is made by spirally winding a second strand 12 onto a first strand 11 using a ring spinning machine. The second strand 12 is made of silver fiber twisted together. Silver fiber has good conductivity, which allows the conductive mesh 3 formed by the conductive yarn 9 to absorb static electricity in the inner layer 1 and transfer it to the outer layer 2 through the conductive strip 4. Static electricity is released by the outer layer 2 fully contacting water molecules in the outside air. Several diverging strips 5 increase the contact area between the outer layer 2 and the outside air, thereby accelerating the release of static electricity from the outer layer 2, resulting in a fabric with good antistatic effect.

[0025] When it is necessary to make this antistatic polyester fabric, firstly, the moisture-absorbing yarn 10 and the conductive yarn 9 are fed into the knitting machine and knitted into an inner layer 1 using a single-sided jacquard weave. Then, the conductive yarn 9 is fed into the knitting machine and knitted into an outer layer 2 using alternating rib and transfer weave. Next, several ventilation holes 7 are opened on the inner layer 1 using a laser cutting machine. After laying the outer layer 2 flat, the inner layer 1 is placed with the side containing the conductive mesh 3 facing up and covers the outer layer 2. The inner layer 1 is moved so that several longitudinal strips 302 are positioned above several conductive strips 4. Finally, the inner layer 1 and the outer layer 2 are sewn together at several conductive parts 201 using a sewing machine with conductive yarn 9, thereby completing the production of this antistatic polyester fabric.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
