Description

Technical Field

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

[0002] Polyester-cotton blend fabric is a type of fabric made from a blend of polyester and cotton fibers. This fabric combines the advantages of both fibers, possessing the elasticity and abrasion resistance of polyester while also having the moisture absorption of cotton.

[0003] Patent document CN208602039U discloses a polyester-cotton blended fabric, which includes a polyester-cotton fabric, an elastic protective fabric on top of the polyester-cotton fabric, a PU film breathable layer on top of the elastic protective fabric, a spring spun UV-resistant fabric on top of the PU film breathable layer, a TPU film resin sweat-absorbing layer on the bottom of the polyester-cotton fabric, a hemp blended fabric on the bottom of the TPU film resin sweat-absorbing layer, and an activated carbon fiber layer on the bottom of the hemp blended fabric.

[0004] The above solution achieves high elasticity, antistatic properties, antibacterial properties, and UV protection by layering multiple functional fabric layers. However, the excessive number of fabric layers makes the finished fabric quite thick, which affects breathability. Furthermore, cotton fibers have poor moisture wicking properties, and after absorbing moisture, the water will block the pores in the fibers, further affecting breathability. This makes the finished fabric feel stuffy when worn, and the inability to quickly wick away moisture after absorption creates a warm and humid environment that is prone to bacterial growth and odor, thus affecting the cleanliness and comfort of the finished fabric.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide antibacterial polyester-cotton fabric.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: antibacterial polyester-cotton fabric, including an inner layer and an outer layer, wherein a support strip is woven into the side of the inner layer near the outer layer, the cross-section of the support strip is grid-shaped, the support strip surrounds a plurality of ventilation grooves on the inner layer, and the bottom surface of the ventilation grooves is formed into a plurality of ventilation holes by burnout processing; a plurality of support strips are woven into the side of the outer layer near the inner layer; the inner and outer layers are supported by the support strips and the plurality of support strips and form a ventilation cavity between the plurality of ventilation grooves; a plurality of ventilation holes are woven into the area of ​​the outer layer between the plurality of support strips, and both the ventilation holes and the ventilation holes are interconnected with the ventilation cavity.

[0008] The present invention is further configured such that: the length of the second support bar is the same as the width of the outer layer, a plurality of the second support bars are arranged in an array along the latitude direction of the outer layer, the width of the second support bar is smaller than the width of the first support bar, and a plurality of the second support bars abut against the first support bar.

[0009] The present invention is further configured such that: the inner layer is a plain weave jacquard weave, the yarn used to weave the inner layer is a moisture-wicking yarn, the moisture-wicking yarn serves as the ground yarn and weft float yarn of the plain weave jacquard weave, and the support strip is formed by a plurality of weft float yarns arranged in a specific pattern.

[0010] The present invention is further configured such that: the moisture-wicking yarn is formed by twisting a first strand and a second strand, wherein the diameter of the first strand is larger than the diameter of the second strand, and the plurality of air-permeable holes are formed by increasing the spacing between the warp and weft threads after the first strand in the processing area is removed by acid hydrolysis in a burnout process.

[0011] The present invention is further configured such that: silicon dioxide powder is added to the second strand, and the first strand is coated with an antibacterial finishing agent.

[0012] The present invention is further configured such that: the outer layer's weaving structure is a combination of raised stripe structure and perforated structure; the outer layer's warp and weft yarns are both moisture-wicking yarns; a plurality of the second support strips are integrally formed on the outer layer by means of raised stripe weaving; and a plurality of the perforated holes are integrally formed on the outer layer by means of perforated weaving.

[0013] In summary, this invention has the following beneficial effects: By adding silica powder to the polyester profiled fibers, the porosity and specific surface area within the fibers are increased, which facilitates gas flow and moisture penetration and diffusion, resulting in fabrics with good moisture-wicking properties. The coating with an antibacterial finishing agent gives the fabrics a certain antibacterial effect. The several ventilation holes 1 and 2, interconnected with the ventilation cavity, enhance airflow between the inside and outside of the fabric, thus achieving good breathability and preventing stuffiness during wear. Simultaneously, the good airflow accelerates moisture wicking from both the inside and outside of the fabric, improving the slow moisture wicking speed within the fabric and preventing the fabric from being in a warm and humid environment for extended periods, thus reducing the risk of bacterial growth and odor, further enhancing the antibacterial effect.

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

[0022] Example: Antibacterial polyester-cotton fabric, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, it includes an inner layer 1 and an outer layer 2. The inner layer 1 has a support strip 3 woven on the side near the outer layer 2. The cross-section of the support strip 3 is grid-like. The weaving structure of the inner layer 1 is a plain weave small jacquard weave. The yarn used to weave the inner layer 1 is a moisture-wicking yarn 9. The inner layer 1 is woven by a multi-arm loom. The moisture-wicking yarn 9 serves as the ground yarn and weft float yarn of the plain weave small jacquard weave. The support strip 3 is formed by several weft float yarns arranged in a row. The moisture-wicking yarn 9 is made by twisting a first strand 10 and a second strand 11 using an "S" twist. The diameter of the first strand 10 is larger than the diameter of the second strand 11, so that the surface of the moisture-wicking yarn 9 is continuously uneven. Therefore, the inner layer 1 woven by the moisture-wicking yarn 9 will form dense gaps, thereby improving the breathability.

[0023] like Figure 1 and Figure 6As shown, the first strand 10 is made by twisting cotton fibers using a twisting machine. The surface of the first strand 10 is coated with an antibacterial finishing agent, which uses nano-silver particles as its core. Nano-silver particles have the characteristics of small particle size and large specific surface area, and have a strong adsorption and inhibition effect on bacteria, so that the inner layer 1 has a good antibacterial effect. The second strand 11 is made of polyester profiled fiber. The profiled cross-section of the polyester profiled fiber is circular. The polyester profiled fiber is made of polyester profiled fiber with added silica powder. Silica powder has a high specific surface area and rich nanoscale pore structure, which can quickly adsorb and conduct moisture and accelerate the evaporation of moisture. Adding silica powder to the polyester profiled fiber is conducive to the circulation of gas and the penetration and diffusion of moisture, so that the fabric itself has good moisture wicking properties. The outer layer 2 is also made of moisture wicking yarn 9. Therefore, the outer layer 2, like the inner layer 1, has good moisture wicking and antibacterial properties.

[0024] like Figure 2 , Figure 3 and Figure 6 As shown, support strip 3 forms several square ventilation grooves 4 on the inner layer 1. Printing paste, an acidic solution, is applied to the bottom surface of the ventilation grooves 4 by a printing machine. The printing roller of the printing machine has several square protrusions arranged in an array on its peripheral wall. These protrusions correspond to the ventilation grooves 4 on the inner layer 1 as the printing roller rotates. Therefore, the printing paste is applied only within the ventilation grooves 4. The printed inner layer 1 is then heat-treated. Because polyester profiled fibers have good acid resistance, while cotton fibers... The poor acid resistance means that the cotton fibers are removed by the printing paste during the heat treatment process. After the burnout process, the inner layer 1 is washed with water to remove impurities and excess printing paste. Several ventilation holes 5 are formed by removing the first strand 10 of the wet-loose yarn 9 through the burnout process to increase the gap between the warp and weft. At the same time, the wet-loose yarn 9 after the burnout process retains the second strand 11, which can ensure the structural strength of the inner layer 1. The air circulation effect on both sides of the inner layer 1 is enhanced through several ventilation holes 5.

[0025] like Figures 1-4As shown, the outer layer 2 has several support strips 6 woven on the side near the inner layer 1. Several ventilation holes 8 are woven in the area between these support strips. The outer layer 2 is constructed using a combination of raised strip and perforated structures. The outer layer 2 is woven using a multi-arm loom, which allows for significant changes in the fabric structure. By controlling the lifting and lowering motion and sequence of the heald frame, the combined weaving of raised strip and perforated structures is achieved. The support strips 6 are integrally formed on the outer layer 2 using a raised strip weaving method, and the ventilation holes are integrally formed on the outer layer 2 using a perforated structure weaving method. The ventilation holes 8 enhance airflow on both sides of the outer layer 2. The inner layer 1 and outer layer 2, supported by the support strips 3 and the support strips, form a ventilation cavity between themselves and the ventilation grooves 4. 7. The length of support strip 2 6 is the same as the width of outer layer 2. Several support strips 2 6 are arranged in an array along the weft direction of outer layer 2. The width of support strip 2 6 is smaller than the width of support strip 1 3. Several support strips 2 6 abut against support strip 1 3, so that several ventilation holes 1 5 and several ventilation holes 2 8 are interconnected with ventilation cavity 7. The ventilation holes 1 5 and several ventilation holes 2 8 interconnected with ventilation cavity 7 enhance the air circulation effect between the inside and outside of the fabric, thereby obtaining good breathability. It is not easy to feel stuffy when wearing. At the same time, the good air circulation effect can accelerate the moisture dissipation speed of the inside and outside of the fabric, improve the slow moisture dissipation speed of the inside of the fabric, and make the fabric less likely to be in a warm and humid environment for a long time, which would breed bacteria and produce odors. This further enhances the breathability, moisture dissipation and antibacterial effect.
