Description

Technical Field

[0001] The utility model relates to the technical field of grey cloth, and more specifically, to a polyester grey cloth. Background Art

[0002] Polyester greige fabric is woven from polyester composite yarn. Polyester fiber has good structural strength and shape retention. Taking advantage of the characteristics of polyester fiber, polyester greige fabric is often used to make daily necessities such as clothing.

[0003] Breathability is the most basic characteristic that clothing fabrics need to have, but polyester fiber itself has poor breathability. Therefore, fabrics made of polyester fiber will also affect the circulation of air on both sides of the fabric during use. Therefore, a structure is set to solve the problem of poor breathability of polyester fabrics. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a polyester grey cloth, which can improve the overall sun protection and air permeability of the cloth through structural settings.

[0005] The above technical purpose of the present utility model is achieved through the following technical solutions: a polyester grey cloth comprises an inner layer and an outer layer fixedly connected to each other, the cross-sectional area of ​​the outer layer is smaller than the cross-sectional area of ​​the inner layer, a plurality of through grooves are integrally formed on the inner layer, a side of the inner layer close to the outer layer is fixedly connected to a plurality of support members staggered with the through grooves, a side of the outer layer close to the inner layer is fixedly connected to a plurality of blocking members with a semicircular cross-sectional shape and the same relative position as the through grooves, and the sum of the widths of the plurality of blocking members is greater than the width of the through grooves.

[0006] The utility model is further configured as follows: a plurality of light-absorbing fleeces are fixedly connected to a plurality of blocking members located on both sides of the through groove in the width direction, and the light-absorbing fleeces are configured as bamboo charcoal fibers.

[0007] The present invention is further configured as follows: the knitting density of the inner layer is smaller than the knitting density of the outer layer, and the height of the supporting member is the same as the height of the blocking member.

[0008] The present invention is further configured as follows: the plurality of support members and the plurality of blocking members are integrally formed with the inner layer and the outer layer respectively, and the inner layer and the outer layer are both configured as tuck structures.

[0009] The present invention is further configured as follows: the inner layer and the outer layer are both woven by composite yarns, and the composite yarns include a first core yarn and a second core yarn.

[0010] The utility model is further configured as follows: the core yarn 1 is formed by twisting polyester fibers, and the core yarn 2 is formed by twisting polyester shaped fibers with a cross-sectional shape.

[0011] To sum up, the utility model has the following beneficial effects: the support member and the blocking member have the same height, which can stably support the inner layer and the outer layer on the one hand, so that there is always flowing outside air inside the fabric; on the other hand, it reduces the situation where the blocking member extends into the through hole to hinder air circulation. The setting of the light-absorbing velvet increases the contact area between the blocking member and the external sunlight, so that the external sunlight can be absorbed or blocked by the light-absorbing velvet first, further reducing the amount of light that passes through the through hole and contacts the body surface, thereby ensuring the sun protection and breathability of the fabric.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0018] A polyester fabric, such as Figure 1 and Figure 2As shown, it includes an inner layer 1 and an outer layer 2 fixedly connected to each other. The setting of the double-layer fabric allows light to be better absorbed and reflected inside the fabric, reducing the amount of light passing through the inner layer 1. The cross-sectional area of ​​the outer layer 2 is smaller than the cross-sectional area of ​​the inner layer 1. Therefore, a stable channel is formed between the two side walls in the width direction of the outer layer 2 and the two side walls in the width direction of the inner layer 1 to allow air to enter. Since the weaving density of the inner layer 1 is less than the weaving density of the outer layer 2, the inner layer 1 can form a number of through grooves 3 when weaving. The setting of the through grooves 3 reduces the contact area between the inner layer 1 and the body surface, and allows the outside air to enter stably. The fabric comes into contact with the body surface through the through groove 3, ensuring the overall breathability and comfort of the fabric. The inner layer 1 is integrally formed with a plurality of support members 4 that are staggered with the through groove 3 on one side close to the outer layer 2, and the outer layer 2 is integrally formed with a plurality of blocking members 5 that are semicircular in cross-section and in the same relative position as the through groove 3 on one side close to the inner layer 1. The setting of the support members 4 and the blocking members 5 can stably support the inner layer 1 and the outer layer 2, ensuring that there is always flowing external air inside the fabric, and since the height of the support members 4 is the same as that of the blocking members 5, the situation where the blocking members 5 penetrate into the through groove 3 and hinder the air circulation is reduced.

[0019] like Figure 1 and Figure 2 As shown, the width of several blocking members 5 is greater than the width of the through groove 3, so the external sunlight will first contact the blocking members 5, reducing the amount of light that passes through the through groove 3 and contacts the body surface. There is a certain space between adjacent through grooves 3 and adjacent blocking members 5, so that the external air can still pass through the space and contact the body surface. Several blocking members 5 located on both sides of the width direction of the through groove 3 are fixedly connected with several light-absorbing fleeces 6. Preferably, several blocking members 5 with the same relative position as the through groove 3 are set to three, so the light-absorbing fleece 6 is set on the two groups of outer blocking members 5. The setting of the position of the light-absorbing fleece 6 further increases the contact area between the blocking members 5 and the external sunlight. Therefore, the blocking members 5 can further absorb external light under the action of the light-absorbing fleece 6, but the external air can still pass through the light-absorbing fleece 6 into the interior of the fabric, so that the fabric can take into account both sun protection and breathability. The light-absorbing fleece 6 is set to bamboo charcoal fiber, and the bamboo charcoal fiber is fixed to the outer wall of the blocking member 5 by electrostatic flocking of a flocking machine. The bamboo charcoal fiber is often darker gray in color, so the light-absorbing fleece 6 can stably absorb external light that contacts it under the action of the bamboo charcoal fiber.

[0020] like Figure 1-Figure 3As shown, a plurality of support members 4 and a plurality of blocking members 5 are respectively integrally formed with the inner layer 1 and the outer layer 2. The inner layer 1 and the outer layer 2 are both arranged as tuck stitches. The pattern of the inner layer 1 and the outer layer 2 is five-way and one-cycle. The core yarn 2 9 passes through the second and third routes and forms a plurality of single-row tuck wales on the inner layer 1 and the outer layer 2. Therefore, the support members 4 and the blocking members 5 are both formed on the single-row tuck wales. However, there is a difference of three stitch lengths between two adjacent single-row tuck wales of the inner layer 1, and there is no difference of stitch lengths between two adjacent single-row tuck wales of the outer layer 2. Based on this rule, three groups of blocking members 5 are formed on the fabric, and then three stitch lengths are formed between two adjacent single-row tuck wales. In this cycle, a plurality of blocking members 5 are formed on the outer layer 2.

[0021] like Figure 1-Figure 3 As shown, the inner layer 1 and the outer layer 2 are both woven by composite yarn 7, and the composite yarn 7 includes core yarn 1 8 and core yarn 2 9. The core yarn 1 8 and core yarn 2 9 are twisted by a twisting machine to form the composite yarn 7. The core yarn 1 8 is twisted by a twisting machine with polyester fiber. The polyester fiber not only has good light resistance, but also has good structural strength. The characteristics of polyester fiber are used to ensure the light resistance and durability of the fabric. The core yarn 2 9 is twisted by a twisting machine with a cross-sectional shape of polyester shaped fiber. The setting of the polyester shaped fiber increases the channel for the outside air to flow through the yarn, so that the fabric can take into account both light resistance and breathability.

[0022] like Figure 1-Figure 3 As shown, when the fabric needs to be made, the composite yarn 7 is placed in a knitting machine and woven into an inner layer 1 and several support members 4 through a tuck-loop weaving method. By reducing the weaving density of the inner layer 1, several through grooves 3 are formed on its surface. The composite yarn 7 is placed in a knitting machine and woven into an outer layer 2 and several blocking members 5 through a tuck-loop weaving method. Glue is applied on the outer peripheral wall of the blocking member 5, and the bamboo charcoal fiber is fixed by electrostatic flocking of a flocking machine to form several light-absorbing flocks 6. Finally, the inner layer 1 and the outer layer 2 are sewn together by a sewing machine.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
