Description

Technical Field

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

[0002] The scientific name for rayon is viscose fiber, which belongs to regenerated cellulose fiber. Viscose fiber has good moisture absorption, but its abrasion resistance is poor and it is prone to pilling during use. Therefore, it often needs to be combined with fabrics with good abrasion resistance before use.

[0003] Increasing the number of fabric layers increases the fabric's thickness. Therefore, if this fabric is used to make clothing, it will affect the airflow and exchange between the two sides of the fabric. When the fabric absorbs sweat from the body, the sweat is more difficult to dissipate through the flowing air, causing sweat to accumulate between the fabric and the body, as well as between adjacent fabrics, affecting the comfort of using the fabric.

[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 rayon fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The rayon fabric includes an inner layer and an outer layer that are fixedly connected to each other. The outer layer has several support strips that abut against the inner layer on the side near the inner layer. The inner layer has several moisture-wicking sheets that abut against the outer layer and have the same thickness as the support strips on the side near the outer layer. The moisture-wicking sheets have more pores than the inner layer. The inner layer has several through holes located on both sides of the moisture-wicking sheets. The inner layer is sewn with several support lines, which are located on the side of the through holes away from the moisture-wicking sheets. The outer layer has several first-stage ventilation holes and several second-stage ventilation holes penetrating the support strips. The inner layer has several grooves on both sides in the thickness direction corresponding to the support strips. Several moisture-absorbing and expanding lines are sewn into the grooves, abutting against the support strips. The diameter of the moisture-absorbing and expanding lines is less than or equal to the depth of the groove. Adjacent moisture-absorbing and expanding lines in the same groove are located at both ends in the width direction of the support strips.

[0007] The present invention is further configured such that: the warp and weft density of the inner layer is greater than that of the outer layer, and the warp and weft density of the inner layer is greater than that of the moisture-wicking sheet.

[0008] The present invention is further configured such that the distance between adjacent through holes arranged along the length direction of the inner layer is less than the distance between adjacent vent hole one and adjacent vent hole two arranged along the length direction of the inner layer.

[0009] The present invention is further configured such that: there are air-permeable channels between adjacent moisture-dissipating sheets, and both the inner and outer layers are configured with a floral structure.

[0010] The present invention is further configured such that: the inner layer is woven from viscose yarn and polyester profiled yarn, wherein the content of viscose yarn is greater than the content of polyester profiled yarn.

[0011] The present invention is further configured such that: the outer layer is woven from polyester profiled yarn two, and the cross-sectional shape of both polyester profiled yarn one and polyester profiled yarn two is cross.

[0012] In summary, this utility model has the following beneficial effects: Due to the high warp and weft density of the inner layer during weaving, the tightly arranged fibers can quickly absorb and diffuse moisture laterally through capillary action, avoiding local water accumulation. The outer layer has a larger thickness in the support strip portion, and the ventilation holes penetrating the outer layer and support strip can accelerate the time required for outside air to pass through the outer layer. Moreover, during the process of passing through the outer layer and support strip, the air volume will not be reduced due to being blocked by fibers, ensuring sufficient air volume to contact the inner layer, thereby shortening the time the inner layer is in a damp state and ensuring the overall moisture absorption and dissipation performance of the fabric.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] This rayon fabric, such as Figure 1 As shown, the fabric includes an inner layer 1 and an outer layer 2 that are sewn together. The outer layer 2 is made of a patterned fabric, so a number of support strips 3 are integrally formed on the side of the outer layer 2 near the inner layer 1, which abut against the inner layer 1. The inner layer 1 is also made of a patterned fabric, so a number of moisture-wicking sheets 4 are formed on the side of the inner layer 1 near the outer layer 2, which abut against the outer layer 2. Since the support strips 3 and the moisture-wicking sheets 4 have the same thickness, the inner layer 1 can always be kept horizontal and in contact with the body surface. The arrangement of the number of support strips 3 and the number of moisture-wicking sheets 4 can stably support the inner layer 1 and the outer layer 2. At the same time, since there are channels for the outside air to flow between each support strip 3 and each moisture-wicking sheet 4, the situation of the inner layer 1 sticking to the outer layer 2 on a large area after being wet with sweat is avoided. Sufficient outside air can come into contact with the inner layer 1 and take away the sweat in the inner layer 1, thus ensuring the moisture absorption and wicking effect of the fabric when it is used.

[0017] The warp and weft density of the inner layer 1 is greater than that of the outer layer 2. Increasing the weaving density means smaller gaps and a more uniform distribution between fibers, resulting in more microcapillary channels. Therefore, the tightly packed fibers in the inner layer 1 can quickly absorb moisture and diffuse it laterally through capillary action, preventing localized excessive moisture on the inner layer 1. At the same time, increasing the weaving density of the inner layer 1 increases the contact points between fibers, allowing the inner layer 1 to absorb more sweat and ensuring good moisture absorption. The warp and weft density of the inner layer 1 is greater than that of the moisture-wicking sheet 4, therefore the weaving density of the moisture-wicking sheet 4... The amount of pores formed during the weaving of the inner layer 1 is greater than that formed during the weaving of the inner layer 1. The increase in pores allows more air to flow in the moisture-wicking sheet 4 and allows more air to come into contact with the inner layer 1. Since the inner layer 1 and several moisture-wicking sheets 4 are integrally formed, some of the sweat in the inner layer 1 will be guided into the moisture-wicking sheet 4, thereby further removing the sweat in the inner layer 1 and the moisture-wicking sheet 4. There are breathable channels between the moisture-wicking sheets 4 formed by the weaving of the patterned structure. Therefore, while ensuring the stable support of the fabric, the amount of air that can flow between the outer layers 2 is increased, allowing the fabric to take into account both moisture absorption and moisture wicking effects.

[0018] The inner layer 1 has several grooves formed on both sides of its thickness direction by a hot press. Several moisture-absorbing and expanding threads are sewn into these grooves using a sewing machine. These threads are made of several strands of wool yarn twisted together. Wool yarn itself has excellent moisture absorption properties, and its diameter expands significantly after absorbing a large amount of water molecules. The diameter of the moisture-absorbing and expanding threads is less than or equal to the depth of the grooves. Therefore, initially, the bottom surface of the inner layer 1 is always in contact with the body surface, and the side of the inner layer 1 closest to the outer layer 2 is always in contact with the support strip 3, thus ensuring the overall moisture absorption effect of the structure. When a large amount of sweat is produced on the body surface and absorbed by the moisture-absorbing and expanding threads, the diameter of the threads increases, thereby increasing the moisture absorption capacity of the inner layer 1. The distance between the inner layer 1 and the support strip 3 allows outside air to flow between them, thus connecting the second ventilation hole 7 and the first ventilation hole 6. This allows the outside air to carry away the sweat remaining inside the support strip 3 and the inner layer 1, enhancing the overall moisture dissipation effect of the structure. Adjacent moisture-absorbing expansion lines located in the same groove are set at both ends of the width direction of the support strip 3 to ensure stable support of the support strip 3 by the adjacent moisture-absorbing expansion lines. Furthermore, the seam between the outer layer 2 and the inner layer 1 is set around the perimeter of the fabric. Therefore, the support strip 3 will not be subjected to pressure from the seam, which would prevent the moisture-absorbing expansion lines from increasing the distance between the inner layer 1 and the outer layer 2, ensuring the stable use of the structure.

[0019] The inner layer 1 has several through holes 5 drilled on both sides of the moisture-wicking sheet 4 using a laser perforation machine. The through holes 5 allow outside air to pass through the inner layer 1 more quickly and come into contact with the body surface. The outer layer 2 has several ventilation holes 6 between adjacent support strips 3 and ventilation holes 7 that pass through both the outer layer 2 and the support strips 3 using a laser perforation machine. The ventilation holes 6 are connected to the through holes 5 through ventilation channels, so outside air can directly contact the body surface along the ventilation holes 6 and the through holes 5, ensuring the breathability and comfort of the fabric during use. Due to the presence of breathable channels, outside air flows between the inner layer 1 and the outer layer 2, thus carrying away sweat from the inner layer 1 more quickly. The distance between adjacent through holes 5 along the length of the inner layer 1 is smaller than the distance between adjacent ventilator 1 6 and adjacent ventilator 2 7 along the length of the inner layer 1. Since the inner layer 1 continuously absorbs sweat from the body surface, reducing the distance between adjacent through holes 5 increases the area of ​​the inner layer 1 that can absorb sweat from the body surface while ensuring the amount of air, allowing the fabric to achieve both moisture absorption and breathability.

[0020] Several support threads are sewn onto the inner layer 1 by a sewing machine, with each support thread located on the side of the through-hole 5 away from the moisture-wicking sheet 4. The support threads sewn by the sewing machine allow several line segments to be formed on both sides of the inner layer 1. The support of the line segments formed between the inner layer 1 and the body surface allows for airflow between the inner layer 1 and the body surface. Since the support threads are sewn onto one side of the through-hole 5, they can support the inner layer 1, increasing the distance between the part of the inner layer 1 forming the through-hole 5 and the body surface. Air passing through the inner layer 1 along the through-hole 5 can flow between the inner layer 1 and the body, increasing the amount of air that can flow between the body surface and the inner layer 1. Because the diameter of the support threads is smaller than the diameter of the yarn required to weave the inner layer 1 and the outer layer 2, only the part of the inner layer 1 that forms the support threads will be away from the body surface. The part of the inner layer 1 away from the support threads will still be in contact with the body surface to absorb sweat.

[0021] The inner layer 1 is woven from viscose yarn and polyester profiled yarn, with the viscose yarn content exceeding the polyester profiled yarn content. The viscose yarn has good moisture absorption properties, ensuring that the inner layer 1 can always absorb sweat from the body surface. Since viscose itself has poor abrasion resistance, a certain amount of high-strength polyester profiled yarn is added to ensure the durability of the inner layer 1. The outer layer 2 is woven from polyester profiled yarn. Both polyester profiled yarn and polyester profiled yarn have a cross-shaped cross section. The addition of polyester profiled yarn increases the channels for air to flow through the yarn, ensuring the overall breathability and comfort of the structure.

[0022] When weaving this fabric, viscose yarn and polyester profiled yarn are placed into a multi-arm loom and woven with a patterned weave to form an inner layer 1 and several moisture-wicking sheets 4. Several through holes 5 are made along the thickness direction of the inner layer 1 using a laser punching machine. Support threads are sewn onto the inner layer 1 using a sewing machine. The inner layer 1 is then heat-pressed by a hot press to form several grooves. Moisture-absorbing and expanding threads are then sewn into the grooves using a sewing machine. Polyester profiled yarn 2 is placed into a multi-arm loom and woven with a patterned weave to form an outer layer 2 and several support strips 3. Several ventilation holes 6 and several ventilation holes 7 are then made along the thickness direction of the outer layer 2 using a laser punching machine. Finally, the inner layer 1 and the outer layer 2 are sewn together using a sewing machine.
