Description

Technical Field

[0001] The utility model relates to the technical field of chemical fiber fabrics, and more specifically, to sun-proof and breathable chemical fiber fabrics. Background Art

[0002] Chemical fiber is a type of spinnable fiber made from natural or artificially synthesized high-molecular compounds through a series of post-finishing preparation technologies. Taking advantage of the characteristics of chemical fiber, chemical fiber fabrics are often used to make clothing and other daily necessities.

[0003] In order to ensure the breathability and comfort of clothing fabrics during use, the fabrics are often made thinner or have more pores in the fabrics. When people are outdoors, the outside sunlight will pass through the pores and shine on the user's body surface. In order to reduce the light transmittance of the fabric, the amount of pores in the fabric is often reduced, but this affects the air circulation on both sides of the fabric. Therefore, a structure is set to solve the problem that some fabrics cannot take into account both sun protection and breathability. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a sun-proof and breathable chemical fiber fabric, which can improve the overall sun-proof and breathable performance of the fabric through structural settings.

[0005] The above technical purpose of the utility model is achieved through the following technical scheme: the sun-proof and breathable chemical fiber fabric includes an inner layer and an outer layer fixedly connected to each other, the inner layer is provided with a plurality of I-shaped cracks, and a plurality of symmetrically arranged blocking sheets are fixedly connected to the inner wall along the length direction of the cracks, the supporting force of the inner layer on the blocking sheets is greater than the gravity of the blocking sheets, and a contact sheet with the same relative position as the crack is fixedly connected to the side of the outer layer close to the inner layer, and the cross-sectional area of ​​the crack is inversely proportional to the distance between the contact sheet and the inner layer.

[0006] The utility model is further configured as follows: the maximum cross-sectional area of ​​the crack is greater than the width of the contact piece, and a plurality of light-blocking fleeces are fixedly connected to the side wall of the contact piece.

[0007] The utility model is further configured as follows: a plurality of through holes are provided on the outer layer, and the contact sheet is located between adjacent through holes arranged along the length direction of the outer layer.

[0008] The utility model is further configured as follows: the outer layer and the contact piece are integrally formed, the outer layer is configured as a warp pattern structure, the ground structure of the warp pattern structure is the outer layer, and the pattern structure of the warp pattern structure is the contact piece.

[0009] The utility model is further configured as follows: the outer layer is woven by shading yarns, and the shading yarns include a shading yarn core and a shading covering yarn spirally wound on the outer side thereof.

[0010] The utility model is further configured as follows: the shading yarn core is formed by twisting polyester fibers, and the shading covering yarn is formed by twisting acrylic fibers.

[0011] The utility model is further configured as follows: the inner layer is woven by composite yarns, the composite yarns include a composite yarn core and a composite covering yarn spirally wound on the outside thereof, the composite yarn core is twisted by bamboo charcoal fibers, and the composite covering yarn is twisted by polyester shaped fibers.

[0012] To sum up, the utility model has the following beneficial effects: in the initial state, the blocking piece can close the crack, reducing the amount of light passing through the inner layer along the crack; when the fabric is subjected to external pressure, the contact piece moves toward the inner layer and applies a thrust to the blocking piece to rotate it toward the user's body surface, so that the contact piece extends into the crack; since the cross-sectional area of ​​the contact piece is smaller than the cross-sectional area of ​​the crack when it is in the maximum state, the channel for external air to flow through between the inner wall of the crack and the outer peripheral wall of the contact piece is increased, thereby ensuring the overall sun protection and breathability performance of the fabric.

DETAILED DESCRIPTION

[0018] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] The sun-proof breathable chemical fiber fabric, such as Figure 1 and Figure 2As shown, it includes an inner layer 1 and an outer layer 2 which are fixedly connected to each other. The inner layer 1 and the outer layer 2 are sewn together by a sewing machine. The setting of the double-layer fabric increases the thickness of the fabric, so that the light entering the interior of the fabric can be better absorbed and reflected inside the fabric, reducing the amount of light passing through the fabric. A number of I-shaped slits 3 are opened along the thickness direction of the inner layer 1 by a laser cutting machine, and a number of symmetrically arranged blocking sheets 4 are fixedly connected to the inner wall along the length direction of the slit 3. The setting of the I-shaped slit 3 allows the blocking sheet 4 to be integrally formed on the inner layer 1. The supporting force of the inner layer 1 on the blocking sheet 4 is greater than the gravity of the blocking sheet 4, so that the blocking sheet 4 can close the slit 3 in the initial state, reducing the light passing through the slit 3 and irradiating the user's body surface, thereby ensuring the sun protection performance of the fabric when used.

[0020] like Figure 1 and Figure 2 As shown, a contact piece 5 having the same relative position as the slit 3 is fixedly connected to one side of the outer layer 2 close to the inner layer 1, and the cross-sectional area of ​​the slit 3 is inversely proportional to the distance between the contact piece 5 and the inner layer 1. During the use of the fabric, the outer layer 2 will drive the contact piece 5 to move toward the inner layer 1, and the contact piece 5 will exert pressure on the barrier piece 4 so that the barrier piece 4 rotates along the connection between it and the inner layer 1 toward the user's body surface. As the barrier piece 4 rotates, the cross-sectional area of ​​the slit 3 increases, thereby increasing the amount of air that passes through the slit 3 and contacts the user's body surface, thereby ensuring the breathability and comfort of the structure when used.

[0021] like Figure 1 and Figure 2 As shown, the maximum cross-sectional area of ​​the slit 3 is greater than the width of the contact piece 5. As the contact piece 5 moves toward the inner layer 1, by setting the width of the contact piece 5, on the one hand, there is always a passage for external air to flow through between the inner wall of the slit 3 and the outer peripheral wall of the contact piece 5. On the other hand, when the contact piece 5 extends into the slit 3, the contact piece 5 will reduce the amount of light that can pass through the inside of the slit 3. Through the structural setting, the fabric can reduce the light transmittance of the fabric while ensuring the air permeability.

[0022] like Figure 1 and Figure 2 As shown, a number of light-blocking fleeces 6 are fixedly connected to the side walls of the contact piece 5, glue is coated on the inner wall of the contact piece 5 by a glue coating machine, and bamboo charcoal fiber 2 is fixed to the side wall of the contact piece 5 by electrostatic flocking using a flocking machine. The bamboo charcoal fiber 2 is usually darker gray in color, so the light-blocking fleece 6 can stably absorb the light entering the interior of the fabric under the action of the bamboo charcoal fiber 2, and the provision of the light-blocking fleece 6 increases the surface roughness of the contact piece 5, so that the light contacting the contact piece 5 can be reflected out under the action of the light-blocking fleece 6, further reducing the amount of light passing through the inner layer 1, thereby ensuring the overall sun protection of the fabric.

[0023] like Figure 1 and Figure 2 As shown, a plurality of through holes 7 are opened along the thickness direction of the outer layer 2 by a laser punching machine, and the contact sheet 5 is located between adjacent through holes 7 arranged along the length direction of the outer layer 2, so that the through holes 7 are not directly connected to the cracks 3, thereby reducing the situation where light enters the fabric along the through holes 7 and directly passes through the cracks 3 to illuminate the user's body surface. The provision of the through holes 7 increases the porosity inside the fabric, so that the inner layer 1 of the fabric can have flowing air for a long time, thereby ensuring the overall sun protection and breathability of the fabric.

[0024] like Figure 1 and Figure 2 As shown, the outer layer 2 and the contact piece 5 are integrally formed, and the outer layer 2 is arranged as a warp pattern structure, the ground structure of the warp pattern structure is the outer layer 2, and the flower structure of the warp pattern structure is the contact piece 5. Through the arrangement of the warp pattern structure, the contact piece 5 can be naturally formed on the surface of the outer layer 2 during weaving, thereby ensuring the stability of the structure during manufacturing and use.

[0025] like Figure 1 and Figure 3 As shown, the outer layer 2 is woven with shading yarn 8, and the shading yarn 8 includes a shading yarn core 9 and a shading covering yarn 10 spirally wound on the outside thereof. The shading yarn core 9 and the shading covering yarn 10 are processed by a spindle spinning process to form the shading yarn 8. The shading yarn core 9 is twisted by a polyester fiber through a twisting machine. The polyester fiber not only has good light resistance but also has good structural strength and shape retention. The light resistance and sun protection of the shading yarn 8 and the outer layer 2 are guaranteed by the setting of the polyester fiber. The shading covering yarn 10 is twisted by an acrylic fiber through a twisting machine. The acrylic fiber has good light resistance, and the structural strength of the acrylic fiber will not decrease even if it is exposed to the sun for a long time. The light resistance and durability of the fabric are guaranteed by the setting of the acrylic fiber.

[0026] like Figure 1 and Figure 4 As shown, the inner layer 1 is woven by composite yarn 11, and the composite yarn 11 includes a composite yarn core 12 and a composite covering yarn 13 spirally wound on the outside thereof. The composite yarn core 12 and the composite covering yarn 13 are processed by spindle spinning to form the composite yarn 11. The composite yarn core 12 is formed by twisting bamboo charcoal fiber through a twisting machine, and the composite covering yarn 13 is formed by twisting polyester shaped fibers with a cross cross section through a twisting machine. The setting of the polyester shaped fibers increases the channel for external air to flow through the inside of the composite yarn 11, thereby increasing the overall breathability and comfort of the fabric.

[0027] like Figure 1-Figure 4As shown, when the fabric needs to be made, the composite yarn 11 is put into a shuttle loom to weave to form an inner layer 1, and the inner layer 1 is cut along the thickness direction by a laser cutting machine to form a slit 3 and a blocking piece 4, and the shading yarn 8 is put into the shuttle loom to weave through the warp pattern weaving method to form an outer layer 2 and a contact piece 5, and the side wall of the contact piece 5 is flocked by a flocking machine to form a light-blocking velvet 6, and then a laser punching machine is used to open a number of through holes 7 along the thickness direction of the outer layer 2, and the inner layer 1 is laid on the table, and then the side of the outer layer 2 forming the contact piece 5 is placed toward the inner layer 1, and finally the inner layer 1 and the outer layer 2 are sewed together by a sewing machine.

[0028] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
