Description

Technical Field

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

[0002] Polyester fabric is a synthetic fabric, also known as polyester fiber. It is made of polyester fibers and has advantages such as being fluffy, lightweight, wrinkle-resistant, wear-resistant, and elastic.

[0003] As people's living standards continue to improve, their demands for fabric performance are also increasing. Most fabrics currently on the market only possess some comfort features, such as stain-resistant and moisture-wicking fabrics, which are relatively simple in function. However, germs are ubiquitous in our living environment, especially in fabrics worn close to the skin, which absorb large amounts of secretions and sweat. To inhibit the growth and reproduction of germs, a large number of antibacterial fabrics have emerged. These fabrics primarily achieve antibacterial properties by adding auxiliaries during the dyeing and finishing process. However, this method has certain limitations in performance; after multiple washes, the antibacterial function of the fabric will be greatly weakened or even disappear. Therefore, a structural solution is needed to address the problem of short-lasting antibacterial activity in fabrics.

[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 antibacterial and moisture-wicking polyester fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: the antibacterial and moisture-wicking polyester fabric includes a strength layer and an antibacterial layer. A plurality of support sheets are fixedly connected between the antibacterial layer and the strength layer. The cross-sectional shape of the support sheets is set to be wavy and distributed along the thickness direction of the antibacterial layer. The support sheets support the air-permeable cavity formed between the antibacterial layer and the strength layer.

[0007] The present invention is further configured such that the support sheet and the antibacterial layer are integrally formed, and the antibacterial layer and the strength layer between adjacent support sheets are fixedly connected.

[0008] The present invention is further configured such that: the antibacterial layer is pleated along its weft direction to form a pleated area, and the support sheet is formed by opening a U-shaped cutting groove on the pleated area.

[0009] The present invention is further configured such that: the weft of the antibacterial layer is chitosan yarn, and the warp of the antibacterial layer includes a plurality of viscose yarns and a plurality of polyester yarns arranged alternately.

[0010] The present invention is further configured such that: a plurality of through holes are formed on the strength layer, and the through holes are connected to the air vent.

[0011] The present invention is further configured such that: the strength layer is configured with a porous structure, and the strength layer is woven from breathable and flat yarns.

[0012] The present invention is further configured such that: the breathable and flat yarn includes a yarn core and an outer sheath spirally wound on its outer side, the yarn core is made of polyester fiber twisted together, and the outer sheath is made of cotton fiber and chitosan fiber twisted together.

[0013] In summary, this utility model has the following beneficial effects:

[0014] The wavy support piece folds and overlaps under the compression of the strength layer and the antibacterial layer, making the support piece more stable along the fabric thickness direction. The design of the ventilation cavity increases the contact area between the antibacterial layer, the strength layer and the air, so that when the air circulates in the ventilation cavity, it accelerates the drying speed of sweat on the antibacterial layer and the strength layer, keeps the fabric dry and slows down the growth of antibacterial bacteria.

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

[0020] This antibacterial and moisture-wicking polyester fabric, such as Figures 1-2As shown, the fabric includes a strength layer 1 and an antibacterial layer 2. The strength layer 1 maintains the flatness of the fabric, making it less prone to deformation during use. The antibacterial layer 2 inhibits the generation and growth of bacteria, enhancing the safety of the fabric. Several support pieces 3 are fixedly connected between the antibacterial layer 2 and the strength layer 1. The cross-sectional shape of the support pieces 3 is set as a wave shape distributed along the thickness direction of the antibacterial layer 2. The wave-shaped support pieces 3 are folded and overlapped under the compression of the strength layer 1 and the antibacterial layer 2, making the support effect of the support pieces 3 along the thickness direction of the fabric more stable. The support pieces 3 support the formation of a breathable cavity 4 between the antibacterial layer 2 and the strength layer 1. The setting of the breathable cavity 4 increases the contact area between the antibacterial layer 2, the strength layer 1 and the air. When the air circulates in the breathable cavity 4, it accelerates the drying speed of sweat on the antibacterial layer 2 and the strength layer 1, keeping the fabric dry and slowing down the growth rate of bacteria.

[0021] like Figures 1-2 As shown, the support piece 3 and the antibacterial layer 2 are integrally formed. The antibacterial layer 2 between adjacent support pieces 3 is fixedly connected to the strength layer 1. After the strength layer 1 and the antibacterial layer 2 are sewn together, they can limit the position of the support piece 3, reducing the shaking of the support piece 3 during the use of the fabric, making the fabric more stable and extending its service life. The antibacterial layer 2 is pleated along its weft direction to form a pleated area. The support piece 3 is formed by opening a U-shaped cutting groove 5 on the pleated area, which makes the connection strength between the support piece 3 and the antibacterial layer 2 higher. At the location of the cutting groove 5, a pleating process is performed along its weft direction to form a pleated area, so that the cross-sectional shape of the support piece 3 cut from the antibacterial layer 2 is wavy. The movable end of the cut support piece 3 rotates downward under the action of gravity, and the length direction of the support piece 3, which is parallel to the antibacterial layer 2, changes to the length direction perpendicular to the antibacterial layer 2. When the antibacterial layer 2 is placed on the strength layer 1, the antibacterial layer 2 and the strength layer 1 press the support piece 3 to fold and support it between the antibacterial layer 2 and the strength layer 1, so as to achieve stable support of the support piece 3 for the antibacterial layer 2 and the strength layer 1.

[0022] like Figures 1-2 As shown, the weft of the antibacterial layer 2 is set as chitosan yarn. Chitosan yarn has a good antibacterial effect, which can ensure the safety and hygiene of the antibacterial layer 2. The warp of the antibacterial layer 2 includes several viscose yarns and several polyester yarns arranged alternately. The viscose yarn has a fast moisture absorption speed, which can quickly absorb the sweat on the body surface to the antibacterial layer 2, accelerate the transfer efficiency of sweat on the body surface, and make the body surface drier and more comfortable. The polyester yarn has good smoothness, which maintains the smoothness of the antibacterial layer 2.

[0023] like Figures 1-2As shown, several viscose yarns and several polyester yarns are alternately threaded and fixed on a water jet loom. Chitosan yarns are woven into the warp threads in a plain weave pattern to obtain an antibacterial layer 2. The woven antibacterial layer 2 is pleated in the area where the warp threads are polyester yarns to form a pleated area. Several cutting grooves 5 are formed by using a laser cutting machine, thereby forming several support pieces 3 with a wavy cross-section.

[0024] like Figures 1-3 As shown, the strength layer 1 has several through holes 6, which are connected to the air vent 4. The through holes 6 facilitate the passage of air through the strength layer 1 into the air vent 4, thereby improving the breathability of the fabric. The strength layer 1 is designed with a perforated structure and is woven from breathable flat yarn 7. The breathable flat yarn 7 includes a yarn core and an outer wrapping yarn spirally wound around its outer side. The yarn core is made by twisting polyester fiber 8, and the outer wrapping yarn is made by twisting cotton fiber 9 and chitosan fiber 10. The cotton fiber 9 and chitosan fiber 10 are twisted by a twisting machine to obtain the outer wrapping yarn, and the polyester fiber 8 is twisted by a twisting machine to obtain the yarn core. The outer wrapping yarn is spirally wound around the outer side of the yarn core by a spinning method to obtain the breathable flat yarn 7. The breathable flat yarn 7 is woven according to the perforated structure weaving method to form the strength layer 1 integrally formed with the through holes 6.

[0025] like Figures 1-2 As shown, the strength layer 1 is laid flat on the worktable. The side of the antibacterial layer 2 with the support piece 3 is close to the strength layer 1. Since the three sides of the support piece 3 are disconnected from the antibacterial layer 2, the support piece 3 hangs down under the action of gravity. The end of the support piece 3 away from the antibacterial layer 2 contacts the strength layer 1. As the antibacterial layer 2 is pressed, the support piece 3 is folded together. Finally, the area between the adjacent support pieces 3 of the strength layer 1 and the antibacterial layer 2 is sewn together by a sewing machine to obtain this fabric.

All technical solutions falling within the scope of this utility model's concept are protected. 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.
