Description

Technical Field

[0001] The present invention relates to the technical field of fabrics, and more specifically, to a light-shielding four-way stretch fabric and its production process. Background Art

[0002] A four-way stretch fabric is a kind of elastic fabric that has good elasticity in both the warp and weft directions. Therefore, the four-way stretch fabric can better adapt to the activities of the human body and is a common fabric used to make clothing.

[0003] In order to ensure the breathability and comfort of the fabric during use, the thickness of the fabric is often reduced or the pore volume inside the fabric is increased. When people are outdoors, external light can more easily pass through the fabric and shine on the user's body surface. In order to reduce the light transmittance of the fabric, the thickness of the fabric is often increased or the pore volume inside the fabric is reduced. At this time, the breathability and comfort of the fabric during use are affected. Therefore, a structure is set up to solve the problem that some fabrics cannot balance sun protection and breathability. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a light-shielding four-way stretch fabric and its production process, and through the setting of the structure, the purpose of improving the overall sun protection and breathability of the fabric is achieved.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: the light-shielding four-way stretch fabric and its production process include a support table and a partition table that are fixedly connected to each other. The support table is arranged on the side of the partition table close to the ground. An additional production part is fixedly connected to the support table, and a main production part is fixedly connected to the partition table. A winding roller is rotatably connected to one end of the partition table away from the main production part. A through groove is opened on the partition table, and a plurality of placement plates passing through the through groove are slidably connected to the support table.

[0006] The present invention is further arranged as: the additional production part includes a processing roller rotatably connected to the support table and a plurality of adsorption plates and bonding plates slidably connected in the height direction of the support table respectively.

[0007] The present invention is further arranged as: the main production part includes a plurality of cutting groove knives and a plurality of rotating tracks. A glue coating part, a bonding part, and a flocking part are slidably connected in the rotating tracks.

[0008] The present invention is further arranged as: the glue coating part includes a receiving plate one sliding in the height direction of the partition table and a plurality of glue applying plates sliding in the width direction of the receiving plate one.

[0009] The present invention is further arranged as: the bonding part includes a receiving plate five sliding in the height direction of the partition table and a plurality of fixing plates slidably connected to the side wall of the receiving plate five. The side of the fixing plate away from the receiving plate five is coated with glue.

[0010] The present invention is further configured as: a light-shielding four-way stretch fabric, processed by the production process of the light-shielding four-way stretch fabric, including a base layer. A plurality of through grooves are formed in the base layer. A plurality of alternately arranged light-absorbing sheets and contact sheets are fixedly connected to the inner wall of the through grooves. The length of the contact sheet is greater than the depth of the through groove. A shielding sheet with the same relative position as the through groove and an arc-shaped cross section is fixedly connected to the base layer. The length of the contact sheet near one end of the shielding sheet is greater than the length of the contact sheet far from the shielding sheet. There is a ventilation space between the inner wall of the contact sheet and the outer wall of the shielding sheet. A blocking strip located in the ventilation space is fixedly connected to the inner wall of the shielding sheet. A plurality of ventilation channels are formed between the blocking strips.

[0011] The present invention is further configured as: the blocking strip is composed of a plurality of blocking lines, and a plurality of blocking nodes are fixedly connected to the outer peripheral wall of the blocking strip. The ventilation space is formed by enclosing a plurality of blocking nodes.

[0012] The present invention is further configured as: the length of the shielding sheet is greater than the width of the through groove, and a plurality of through holes with the same relative position as the blocking lines are formed in the shielding sheet.

[0013] The present invention is further configured as: the thickness of the light-absorbing sheet is less than the thickness of the contact sheet. The light-absorbing sheet is provided as a plurality of light-absorbing fluffs, and a plurality of bamboo charcoal fibers I are included in the light-absorbing sheet.

[0014] The present invention is further configured as: the base layer is woven by high-elastic yarns. The high-elastic yarns include a high-elastic yarn core and a high-elastic covering yarn. The high-elastic yarn core is twisted by spandex fibers, and the high-elastic covering yarn is twisted by polyester fibers I.

[0015] In summary, the present invention has the following beneficial effects: The setting of the shielding sheet reduces the amount of light directly passing through the through groove and contacting the user's body surface. Since the contact sheet does not abut against the shielding sheet, the air entering the fabric can flow between the base layer and the shielding sheet along the space between the contact sheet and the shielding sheet. The setting of the blocking lines can, on the one hand, better absorb the external light contacting it, and on the other hand, the external air can pass out along the ventilation space and the through holes, ensuring the sun protection and breathability of the structure during use.

Specific embodiments

[0018] The following combines the drawings and embodiments to describe the present invention in detail.

[0019] The light-shielding four-way stretch fabric, as Figures 8 - 10 shown, includes a base layer 1. The single-layer fabric speeds up the air exchange rate on both sides of the fabric. A plurality of through grooves 2 are provided along the thickness direction of the base layer 1. The provision of the through grooves 2 increases the channels for external air to flow through inside the fabric, ensuring the overall breathability of the fabric. Alternately arranged a plurality of light-absorbing sheets 3 and contact sheets 4 are fixedly connected to the inner wall of the through groove 2. The light-absorbing sheets 3 and contact sheets 4 reduce the width of the through groove 2, thereby reducing the amount of light passing through the through groove 2. Moreover, the provision of the light-absorbing sheets 3 and contact sheets 4 increases the surface roughness of the inner wall of the through groove 2, enabling the light in contact with the inner wall of the through groove 2 to be stably dissipated, ensuring the sun protection property when the fabric is used.

[0020] As Figure 8 and Figure 9As shown, the length of the contact piece 4 is greater than the depth of the through groove 2. Both ends of the contact piece 4 are higher than the base layer 1. The length of the contact piece 4 near the shielding piece 5 is greater than the length of the contact piece 4 away from the shielding piece 5. During the use of the fabric, it will contact with external substances, which may cause deformation of the structure on the fabric. When the contact piece 4 is under pressure and rotates away from the through groove 2, the contact piece 4 abuts against the base layer 1, thereby increasing the thickness of the base layer 1 and reducing the contact area between the base layer 1 and external substances. This enables the contact piece 4 to come into contact with external substances first when the fabric is in use. When the contact piece 4 is completely worn out, the base layer 1 will start to rub against external substances, strengthening the wear resistance of the structure by extending the time for the base layer 1 to be worn out.

[0021] As Figure 8 and Figure 9 shown, when the contact piece 4 is under external pressure and rotates towards the through groove 2, since the width of the through groove 2 is greater than the thickness of the contact piece 4, the contact piece 4 can rotate into the through groove 2. The rotating contact piece 4 can further close the through groove 2, reducing the light passing through the through groove 2 and further reducing the light transmittance of the fabric.

[0022] As Figure 8 and Figure 9 shown, a shielding piece 5 with the same relative position as the through groove 2 and an arc-shaped cross-section is bonded to the base layer 1. The setting of the shielding piece 5 can stably close the through groove 2, reducing the amount of light passing through the through groove 2 and directly contacting the user's body surface. Moreover, the setting of the shielding piece 5 reduces the contact area between the base layer 1 and the user's body surface, creating a channel for external air to flow between the base layer 1 and the user's body surface, ensuring the sun protection and breathability of the fabric during use through the structural design.

[0023] As Figure 8 and Figure 9 shown, there is a ventilation space between the inner wall of the contact piece 4 and the outer wall of the shielding piece 5. Fixedly connected to the inner wall of the shielding piece 5 are blocking strips located in the ventilation space, and several ventilation channels are formed between the blocking strips. The length of the contact piece 4 extending out of the base layer 1 near the shielding piece 5 is less than the distance between the shielding piece 5 and the base layer 1, enabling the external air and light entering the fabric through the through groove 2 to stably enter the ventilation space. The external light entering the interior of the shielding piece 5 will be absorbed by the blocking strips, and the external light entering the ventilation air will flow in the shielding piece 5 along the ventilation channels, ensuring the sun protection and breathability performance of the fabric during use.

[0024] As Figures 8 - 10As shown, the barrier strip is composed of a number of barrier lines 6. A number of barrier nodes 7 are fixedly connected to the outer peripheral wall of the barrier strip. The barrier nodes 7 and the barrier lines 6 are integrally formed. The barrier lines 6 are set as slub yarns. The ventilation space is formed by enclosing a number of barrier nodes 7, ensuring that the outside air can flow stably within the barrier strip and guaranteeing the breathability of the structure. A number of barrier lines 6 are bound together by yarns to form the barrier strip. The barrier strip abuts against the outer peripheral wall of the contact piece 4, and the barrier strip provides a supporting force to the contact piece 4, thereby restricting the rotation angle of the contact piece 4, and thus reducing the divergence of the outside light within the fabric as the contact piece 4 rotates, further optimizing the light-shielding and sun-protection performance of the structure.

[0025] As Figures 8 - 10 shown, the length of the shielding piece 5 is greater than the width of the through groove 2. Therefore, after both ends of the shielding piece 5 are fixed on the base layer 1, the middle part of the shielding piece 5 will naturally droop under the action of gravity, making its cross-section arc-shaped. A number of through holes 11 are provided on the shielding piece 5 at the same relative positions as the barrier lines 6. The setting of the through holes 11 increases the porosity inside the shielding piece 5, enabling the air entering the ventilation channel to stably pass through the through holes 11 and contact the user's body surface, ensuring the breathable comfort of the fabric during use.

[0026] As Figures 8 - 10 shown, the thickness of the light-absorbing piece 3 is less than the thickness of the contact piece 4. While ensuring the stable light-absorbing effect of the light-absorbing piece 3, it increases the channel for air to flow through within the through groove 2. The light-absorbing piece 3 is set as a number of light-absorbing fluffs. The light-absorbing piece 3 includes a number of bamboo charcoal fibers I. The bamboo charcoal fibers I are usually dark gray in color. Therefore, the light-absorbing fluffs can stably absorb the light entering the through groove 2 under the action of the bamboo charcoal fibers I, further reducing the light transmittance of the fabric.

[0027] As Figure 8 and Figure 11 shown, the base layer 1 is woven by high-elastic yarns 8 through a loom. The high-elastic yarns 8 include a high-elastic yarn core 9 and high-elastic covering yarns 10. The high-elastic yarn core 9 and the high-elastic covering yarns 10 are processed into high-elastic yarns 8 through the mule spinning process. The high-elastic yarn core 9 is formed by twisting spandex fibers through a twisting machine. The spandex fibers have good elasticity. Utilizing the characteristics of the spandex fibers enables the base layer 1 to reset under the action of its own elastic deformation performance after the external pressure disappears, ensuring the elasticity of the fabric. The high-elastic covering yarns 10 are formed by twisting polyester fibers I through a twisting machine. The polyester fibers I not only have good light resistance but also have good structural strength, ensuring the light and abrasion resistance of the fabric through the characteristics of the polyester fibers I.

[0028] As Figure 8 and Figure 9As shown, the light-blocking sheet 5 is woven by a shuttle loom using light-blocking yarns. The light-blocking yarns include a light-blocking yarn core and a light-blocking covering yarn. The light-blocking yarn core and the light-blocking covering yarn are processed into light-blocking yarns through a mule spinning process. The light-blocking yarn core is formed by twisting two bamboo charcoal fibers, and the light-blocking covering yarn is formed by twisting a polyester profiled fiber 1 with a cross-shaped cross-section through a twisting machine. By setting the polyester profiled fiber 1, the channels for external air to flow through inside the fabric are increased, enhancing the air permeability during the use of the structure.

[0029] As Figures 8 - 10 shown, polyester fiber 2 and bamboo charcoal fiber 3 are put into a fancy twisting machine and woven in the form of slub yarns to form a blocking line 6, and a number of blocking nodes 7 are formed on its surface. The two ends of a number of blocking lines 6 are fixed together by yarns, reducing the situation where a number of blocking lines 6 move inside the fabric. The contact sheet 4 is formed by twisting a polyester profiled fiber 2 with a Y-shaped cross-section through a twisting machine. The setting of the polyester profiled fiber 2 increases the air flowing out of the contact sheet 4 while ensuring its good light resistance, ensuring the air permeability of the structure.

[0030] As Figure 8 、 Figure 9 、 Figure 1 and Figure 2 shown, it includes a support table 14 and a partition table 13 that are welded to each other. An additional manufacturing part for making the light-blocking sheet 5 is placed on the support table 14, and a main manufacturing part for making the base layer 1 is placed on the partition table 13. A feeding roller 1 is rotatably connected to the side wall of the support table 14 and is driven by a motor 1. The light-blocking sheet 5 is placed on the feeding roller 1, and the light-blocking sheet 5 is conveyed forward by starting the motor 1. A feeding roller 2 16 is rotatably connected to the side wall of the partition table 13 and is driven by a motor 2. The base layer 1 is wound around the feeding roller 2 16, and the base layer 1 is conveyed forward by starting the motor 2.

[0031] As Figure 8 、 Figure 9 、 Figure 10 、 Figure 1 、 Figure 5 and Figure 7As shown in the figure, the additional manufacturing section includes a processing roller 25 rotatably connected to the support table 14, several suction plates 30 and bonding plates 31 respectively slidably connected in the height direction of the support table 14. A motor three for driving the rotation of the processing roller 25 is fixedly connected to the side wall of the support table 14 by bolts. A second receiving plate 27 and a third receiving plate 28 are respectively slidably connected to the outer peripheral wall of the processing roller 25. The second receiving plate 27 and the third receiving plate 28 are symmetrically arranged along the central axis of the length direction of the processing roller 25, reducing the collision during the sliding process of the second receiving plate 27 and the third receiving plate 28. Both the second receiving plate 27 and the third receiving plate 28 are connected to the processing roller 25 through a first electric telescopic rod. Several punching knives 26 are welded on the second receiving plate 27, and several adhesive plates are welded on the third receiving plate 28. The width of the adhesive plate is smaller than the diameter of the punching knife 26, thereby reducing the area of the through hole 11 blocked by the glue. When the shielding piece 5 moves below the processing roller 25, by extending the length of the first electric telescopic rod, the punching knife 26 and the adhesive plate are successively abutted against the shielding piece 5, thereby forming the through hole 11 on the fabric and coating the glue.

[0032] As Figure 8 , Figure 9 , Figure 1 and Figure 7 shown, the suction plate 30 is connected to the top surface of the support table 14 through a second electric telescopic rod. Several blocking wires 6 are fixed into a bundle by an automatic bundling machine to form a blocking strip, and the blocking strip is adsorbed in the suction plate 30. When the fabric moves below the suction plate 30, by controlling the length of the second electric telescopic rod, the suction plate 30 moves towards the direction close to the bottom surface of the support table 14, so that the blocking strip is bonded to the shielding piece 5.

[0033] As Figure 8 , Figure 9 , Figure 1 , Figure 4 and Figure 7 shown, a sliding groove 15 is opened on one side of the support table 14 away from the first feeding roller. Several sliding tracks are opened in the sliding groove 15. The placing plate 22 is slidably connected in the sliding tracks through a third electric telescopic rod. A placing groove 23 with an arc-shaped cross-section is opened in the placing plate 22. The top surface of the placing plate 22 is in the same plane as the top surface of the support table 14, and the top surface of the placing plate 22 is lower than the support table 14. In the initial state, one end of the placing plate 22 abuts against the inner wall of the sliding groove 15, so that the shielding piece 5 bonded with the blocking strip can stably move into the placing plate 22. At this time, the length of the first electric telescopic rod is increased, so that the bonding plate 31 moves towards the fabric to coat the glue on the shielding piece 5.

[0034] As Figure 8 , Figure 1 , Figure 2 and Figure 3As shown, the main production part includes several grooving knives 17 and several rotating tracks 18. A glue coating part, an adhesive bonding part and a flocking part are slidably connected in the rotating tracks 18. The grooving knives 17 are slidably connected in the height direction of the partition table 13 through a fourth bearing plate. When the fourth bearing plate and the partition table 13 move to below the grooving knives 17 by the electric telescopic rod four, the length of the electric telescopic rod four increases, so that the grooving knives 17 move towards the direction close to the fabric, thereby forming a through groove 2 on the base layer 1.

[0035] As Figure 9 , Figure 1 and Figure 3 As shown, the glue coating part includes a first bearing plate slidably connected in the height direction of the partition table 13 and several glue spreading plates 19 slidably connected in the width direction of the first bearing plate. A plurality of moving grooves one are respectively opened on the side wall of the first bearing plate. Electric telescopic rods five are fixedly connected in the moving grooves one through bolts. The glue spreading plates 19 are bonded to the electric telescopic rods five. The shortest lengths of the first bearing plate and the electric telescopic rods five and the thickness of the glue spreading plates 19 are less than the width of the through groove 2, so that the first bearing plate and the glue spreading plates 19 can stably penetrate into the through groove 2. After penetrating into the through groove 2, the length of the electric telescopic rod five is increased, so that the glue spreading plates 19 can move towards the direction close to the inner wall of the through groove 2 driven by the electric telescopic rods five, thereby coating the glue on the inner wall of the through groove 2.

[0036] As Figure 8 , Figure 9 , Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, the adhesive bonding part includes a fifth bearing plate 24 slidably connected in the height direction of the partition table 13 and several fixing plates 20 slidably connected to the side wall of the fifth bearing plate 24. When the fourth bearing plate first moves above the fabric on the rotating track 18, the fourth bearing plate moves towards the direction close to the fabric until it extends into the through groove 2 and coats the glue on the inner wall of the through groove 2. After the coating is completed, the fourth bearing plate moves towards the direction close to the top surface of the partition table 13 and moves along the rotating track 18. When the fifth bearing plate 24 moves above the fabric, the fifth bearing plate 24 drives the fixing plates 20 to move towards the direction close to the fabric and move into the through groove 2, thereby bonding the contact pieces 4 on the fixing plates 20 to the inner wall of the through groove 2.

[0037] As Figure 8 and Figure 3 As shown, the flocking part is arranged as a flocking box 21 bonded to the sixth bearing plate and communicating with the inside of the sixth bearing plate. The sixth bearing plate is provided with a fluff outlet communicating with the outside. When the sixth bearing plate penetrates into the through groove 2, the light-absorbing fluff in the flocking box 21 is bonded to the inner wall of the through groove 2 through the fluff outlet.

[0038] As Figure 8 , Figure 9 , Figure 1 ,Figure 4 and Figure 6 As shown, a through slot 29 is opened on the partition table 13. After the shielding sheet 5 is moved to the placement plate 22 after processing, the length of the electric telescopic rod three is increased so that it can drive the placement plate 22 to pass through the through slot 29 and move to abut against the base layer 1, thereby bonding the shielding sheet 5 to the base layer 1. The end of the partition table 13 away from the main production part is rotatably connected to the winding roller 12. The winding roller 12 is rotated by the motor four to stably wind up the finished fabric, which is convenient for the subsequent storage and use of the fabric.

[0039] The above is only a preferred embodiment of the present invention, and 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.
