Description

Technical Field

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

[0002] Polyester fabric is a type of fabric woven from polyester fibers. Polyester fibers are synthetic fibers made by chemical condensation of organic dibasic acids and diols. They have high strength and abrasion resistance, making fabrics made from polyester yarns strong and durable. They are widely used in the textile industry and are commonly used in the production of clothing, home decoration, tents, umbrellas, and other products.

[0003] However, polyester fibers have poor moisture absorption, so polyester fabrics are usually in a relatively dry environment. This makes polyester fabrics prone to generating static electricity due to friction during wear. However, polyester fibers have poor conductivity, so the generated static electricity cannot be discharged and dispersed in time, but accumulates inside the fabric. This makes polyester fabrics prone to static electricity adhering to the skin surface, and the static electricity accumulated inside the polyester fabric can irritate the skin and affect the wearing comfort.

[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 antistatic polyester fabric to solve the problem of static electricity easily generated in polyester fabric during wear.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The antistatic polyester fabric includes an inner layer and an outer layer that are fixedly connected to each other. The outer layer has several grooves on both sides, and the bottom surface of the grooves is provided with several through-holes that penetrate the outer layer. The inner layer has several protrusions on its end face near the outer layer. The peripheral walls of the protrusions abut against the inner walls of several grooves on the side of the outer layer near the inner layer. Several conductive elements are provided between the inner layer and the outer layer. The peripheral walls of the conductive elements abut against the end faces of the inner layer and the outer layer that are close to each other.

[0007] The present invention is further configured such that: a plurality of grooves on both sides of the outer layer are symmetrically arranged along the length of the fabric, the plurality of grooves on both sides of the outer layer are of the same size and are symmetrically arranged vertically, and the plurality of outlet holes are simultaneously connected to the plurality of grooves on both sides of the outer layer.

[0008] The present invention is further configured such that: the outer layer is made by a plain weave of conductive yarn, the conductive yarn is made by twisting a first strand and a second strand, the first strand is made by twisting silver fiber, the second strand is made by twisting polyester profiled fiber with a six-lobed cross section, and the count of the first strand is greater than the count of the second strand.

[0009] The present invention is further configured such that the alkali resistance of the polyester shaped fiber is lower than that of the silver fiber, and the plurality of outlet holes on the inner layer and the plurality of grooves on both sides are formed by dissolving the first strand in the processing area through an alkali melting process.

[0010] The present invention is further configured such that: the width of the protrusion is the same as the width of the groove, the thickness of the protrusion is greater than the depth of the groove, and several adjacent protrusions form several cavities between the inner layer and the outer layer.

[0011] The present invention is further configured such that: the plurality of protrusions are integrally woven by a braiding method of the inner layer with convex strips, the plurality of conductive elements are arranged in the cavity, and the conductive elements are cut by twisting together multiple strands of conductive yarn.

[0012] The present invention is further configured such that: the inner layer is woven from moisture-absorbing yarn, the moisture-absorbing yarn is made by spirally winding a third strand around a second strand, and the third strand is made by twisting cotton fibers.

[0013] The present invention is further configured such that the inner layer and the outer layer are fixedly connected together by conductive yarn passing through the inner layer, the outer layer and the conductive component and being stitched back and forth.

[0014] In summary, this utility model has the following beneficial effects: the hexagonal cross-section of the polyester profiled fiber provides a larger surface area and porosity, increasing the moisture regain rate of the polyester profiled fiber and thus improving its antistatic properties. Cotton fiber has good hygroscopicity; by wrapping the polyester profiled fiber with cotton fiber, static electricity is avoided from being generated by friction between the polyester profiled fiber and external objects, while ensuring a certain level of humidity on the surface of the polyester profiled fiber, resulting in a good antistatic effect for the inner layer. Silver fiber has good conductivity; the static electricity generated in the inner layer can be promptly transferred to the outer layer through several conductive elements and several protrusions. The outer layer made of silver fiber can promptly conduct the static electricity from its interior, preventing static electricity from accumulating inside the fabric. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Example: The antistatic polyester fabric, as shown in Figure 1- Figure 4 As shown, the outer layer 2 consists of an inner layer 1 and an outer layer 2 that are fixedly connected to each other. The outer layer 2 is woven by feeding conductive yarn 7 into an air-jet loom and using a plain weave. The conductive yarn 7 is formed by twisting a first strand 8 and a second strand 9 using an "S" twisting method. The first strand 8 is formed by twisting silver fiber using a twisting machine, and the second strand 9 is formed by twisting polyester profiled fiber with a hexagonal cross-section using a twisting machine. The hexagonal polyester fiber is spun through a spinneret with hexagonal spinneret holes. The hexagonal polyester profiled fiber has a larger surface area and porosity, which improves the moisture regain and hygroscopicity of the polyester profiled fiber, allowing it to absorb more moisture from the surrounding environment, thereby improving the conductivity of the polyester profiled fiber. The silver fiber itself has good conductivity, allowing the outer layer 2, made by the first strand 8 and the second strand 9, to conduct static electricity generated inside in a timely manner.

[0023] As shown in Figures 1 and 4, and Figure 5 As shown, the silver fiber content in outer layer 2 is twice that of polyester profiled fiber in outer layer 2. The count of the first strand 8 is greater than that of the second strand 9, making the diameter of the first strand 8 smaller than that of the second strand 9. By increasing the silver fiber content, the conductivity of outer layer 2 is improved while reducing the contact area between polyester profiled fiber and external objects. Inner layer 1 is woven by feeding moisture-absorbing yarn 11 into an air-jet loom and using a ribbed weave. The moisture-absorbing yarn 11 is made by tightly winding a third strand 12 onto a second strand 9 using a spinning process. The third strand 12 is made by twisting cotton fiber. Cotton fiber has strong moisture absorption and antistatic properties, avoiding static electricity generated by contact friction between the polyester profiled fiber in inner layer 1 and the skin. The good moisture absorption and softness of cotton fiber improve the soft touch of inner layer 1 and can absorb the sweat produced by the wearer's skin in time, so that a water molecule film is formed between the cotton fiber and the polyester profiled fiber, thereby preventing the second strand 9 from being trapped. Friction between the third strand 12 and the third strand is less likely to generate static electricity.

[0024] As shown in Figure 1- Figure 3As shown, the outer layer 2 has several rectangular grooves 3 on both sides. The grooves 3 on both sides of the outer layer 2 are symmetrically arranged along the length of the fabric. The grooves 3 on both sides of the outer layer 2 are the same size and symmetrically arranged vertically. The bottom surface of the grooves 3 is arrayed with several outlet holes 4 that penetrate the outer layer 2. The alkali resistance of polyester profiled fiber is lower than that of silver fiber. The outlet holes 4 on the outer layer 2 and the grooves 3 on both sides are formed by dissolving the first strand 8 in the processing area through an alkali melting process. The outlet holes 4 make the grooves 3 on both sides of the outer layer 2 interconnected, thereby increasing the air permeability and contact area of ​​the outer layer 2 and improving the speed at which the outer layer 2 conducts its internal static electricity to the surrounding environment.

[0025] As shown in Figure 1- Figure 3 As shown, the inner layer 1 has several elongated protrusions 5 symmetrically arranged along the length of the fabric on the end face near the outer layer 2. The protrusions 5 are integrally formed on the inner layer 1 by a woven strip structure. The cross-sectional shape of the protrusions 5 is rectangular, and the width of the protrusions 5 is the same as the width of the grooves 3. By abutting the peripheral walls of the protrusions 5 against the inner walls of the grooves 3 on the side of the outer layer 2 near the inner layer 1, the static electricity generated in the inner layer 1 can be transferred to the outer layer 2 and quickly discharged. The thickness of the protrusions 5 is greater than the depth of the grooves 3, so that several adjacent protrusions 5 form several rectangular cavities 10 between the inner layer 1 and the outer layer 2. The cavities 10 reduce the friction area between the inner layer 1 and the outer layer 2, thereby reducing the generation of static electricity.

[0026] As shown in Figure 1- Figure 4 As shown, several cylindrical conductive elements 6 are provided between the inner layer 1 and the outer layer 2. The conductive elements 6 are arranged in the cavity 10. The conductive elements 6 are formed by twisting two strands of conductive yarn 7 together with a twisting machine and then cutting them with a cutting machine. The diameter of the conductive elements 6 is the same as the cross-sectional width of the cavity 10, so that the peripheral walls of the conductive elements 6 simultaneously abut against the end faces of the inner layer 1 and the outer layer 2 that are close to each other. The inner layer 1 and the outer layer 2 are fixed together by sewing the conductive yarn 7 through the inner layer 1, the outer layer 2 and the conductive elements 6 back and forth. The conductive yarn 7 and the conductive elements 6 used to sew the inner layer 1 and the outer layer 2 accelerate the transfer of static electricity in the inner layer 1 to the outer layer 2, so that the fabric can conduct static electricity from its interior in time and avoid the static electricity in the inner layer 1 from irritating the skin.
