Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical fiber fabrics, and more specifically, to high-strength and high-elastic nylon fabrics. Background Art
[0002] Tarpaulin (or waterproof cloth) is a high-strength, tough and soft waterproof material, commonly used to build shelter structures such as tents, awnings, truck tarpaulins, and stall covers in open-air markets. It usually has functions such as waterproofing, windproofing, and sun protection, and is widely used in outdoor activities, construction sites, agriculture, commerce, and other fields;
[0003] However, when a tarpaulin is generally used to block rain, it is necessary to tilt the tarpaulin over the covered object, and use the gravity of the rainwater to make it flow along the surface of the tarpaulin toward the edge of the tarpaulin. However, after the rain stops, some rainwater will be adsorbed on the surface of the tarpaulin. When the tarpaulin needs to be removed and stored, it is generally stored in a folded or curled manner. The rainwater attached to the surface of the tarpaulin is subjected to the adsorption force of the two tarpaulin surfaces that are squeezed against each other, so that the rainwater cannot use its own gravity to flow out from the gap of the curled tarpaulin, causing the rainwater to be unable to be discharged from the curled tarpaulin and increase the humidity on the surface of the tarpaulin. A relatively sealed environment is formed inside the curled tarpaulin. The humid and sealed environment promotes bacteria on the surface of the tarpaulin itself and corrodes the tarpaulin, thereby reducing the service life of the tarpaulin. At the same time, bacterial growth will cause a foul odor on the surface of the tarpaulin, affecting the next use experience.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0020] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] Example:
[0022] High-strength and high-elastic nylon fabrics, such as Figures 1 to 4As shown, the outer layer 11 includes an outer layer 11, a rubber layer 12, and an inner layer 13. The outer layer 11 is provided with a water diversion surface 14 on a side away from the inner layer 13. The outer layer 11 is provided with a first drainage groove 15 between the water diversion surface 14. A plurality of through holes 16 are provided in the first drainage groove 15. The rubber layer 12 is arranged between the outer layer 11 and the inner layer 13. A plurality of second drainage grooves 17 are provided on a side of the rubber layer 12 contacting the outer layer 11. The first drainage groove 15 is connected to the second drainage groove 17 through the through holes 16. The water diversion surface 14 is used to drain rainwater on the surface of the outer layer 11 into the first drainage groove 15, and then the rainwater in the first drainage groove 15 is drained into the second drainage groove 17 through the through holes 16. The fabric is erected and the edge of the fabric is at the lowest position, and then the rainwater is directed to the edge of the fabric by its own gravity through the second drainage groove 17, thereby increasing the water conductivity of the fabric. At the same time, when collecting the fabric, the side of the fabric in the outer layer 11 is first folded and abutted, and then the folded fabric is curled, so that the surface of the outer layer 11 abuts against the surface of the outer layer 11 at another position. During the folding and curling process, the abutting outer layers 11 generate friction, and at the same time, the protruding positions of the water diversion surfaces 14 abut against each other, while there are gaps between the concave positions of the water diversion surfaces 14, so that the rainwater gathers at the gaps between the abutting water diversion surfaces 14, thereby increasing the unit area of the concave positions of the water diversion surfaces 14. The amount of rainwater in the domain, that is, the gravity of rainwater in the depression of the water diversion surface 14 is greater than the adhesion between the rainwater and the surface of the water diversion surface 14, so that the rainwater can flow along the vertical surface of the water diversion surface 14 to the edge of the fabric, reducing the amount of rainwater on the surface of the fabric in the curled state, preventing bacteria from growing, and thus increasing the service life of the fabric. The outer layer 11 includes nylon fiber 18 and polypropylene fiber 19, and the inner layer 13 includes nylon fiber 18, spandex fiber 20, and PTT fiber 21. The inclination angle of the side wall of the first drainage groove 15 is greater than the inclination angle of the water diversion surface 14. At the same time, the polypropylene fiber 19 woven into the outer layer 11 is used to increase the waterproofness of the outer layer 11 to prevent rainwater from penetrating into the fabric through the outer layer 11. Inside, the inner layer 13 is woven by spandex fiber 20 and PTT fiber 21, and the elasticity of the inner layer 13 is increased. When the fabric is curled, the pressure at the abutment point of the water diversion surface 14 can be increased, so that the rainwater on the surface of the water diversion surface 14 can be pressed into the first drainage groove 15, the through hole 16 and the second drainage groove 17, thereby increasing the collection effect of rainwater on the fabric surface, and then increasing the discharge effect of rainwater on the fabric surface. At the same time, the inclination angle of the side wall of the first drainage groove 15 is greater than the inclination angle of the water diversion surface 14, which further increases the effect of rainwater entering the first drainage groove 15 from the surface of the water diversion surface 14, and then the characteristics of the nylon fiber 18 are used to increase the strength and durability of the fabric.
[0023] like Figure 1 and Figure 3As shown, the outer layer 11 includes waterproof yarn, the weaving density of the waterproof yarn in the warp and weft directions is 82 yarns / cm, and the count of the waterproof yarn is 50S. The tight weaving density of the outer layer 11 is used to further increase the waterproof effect of the outer layer 11 to prevent rainwater from penetrating the fabric.
[0024] like Figure 1 and Figure 4 As shown, the inner layer 13 includes elastic yarns, the weaving density of the elastic yarns in the warp direction is 56 yarns / cm, the weaving density of the elastic yarns in the weft direction is 64 yarns / cm, and the count of the elastic yarns is 95S. The weaving density of the elastic yarns in the inner layer 13 is utilized to increase the tensile strength of the fabric, and at the same time, the fabric has a stronger elastic modulus, thereby increasing the use effect of the fabric.
[0025] like Figure 1 and Figure 2 As shown, the outer layer 11 is a reinforced twill structure, and its thickness is increased by the reinforced twill structure. The reinforced twill structure has six pages and the warp floating points are floating and the weft floating points are sinking. The organizational cycle of the reinforced twill structure from left to right and from bottom to top is: floating, floating, floating, sinking, sinking, floating, floating, sinking, floating, floating, floating, floating, floating, floating, sinking, floating, floating, floating, floating, sinking, floating, and floating. The thickness of the fabric is increased by utilizing the structure of the reinforced twill structure. When a hot press is used to form a water diversion surface 14 on the surface of the outer layer 11, the water diversion surface 14 has an inclined angle, thereby increasing the effect of transferring rainwater on the surface of the water diversion surface 14 to the first drainage ditch 15.
[0026] like Figure 3 As shown, the waterproof yarn includes polypropylene fiber 19 and nylon fiber 18. The polypropylene fiber 19 is parallel to the outside of the nylon fiber 18 and twisted together with the nylon fiber 18. The twist of the polypropylene fiber 19 is 150 twists / m. By utilizing the twisting method of the polypropylene fiber 19 arranged on the outside of the nylon fiber 18 and the high twist setting of the polypropylene fiber 19, when the waterproof yarn is used to weave the outer layer 11, the polypropylene fiber 19 is kept in contact with the outside world, and then the waterproof performance of the polypropylene fiber 19 is used to increase the waterproof effect of the outer layer 11, further increase the ability of the outer layer 11 to isolate water, and increase the waterproofness of the fabric.
[0027] like Figure 4As shown, the elastic yarn includes a core yarn and an outer yarn. The core yarn is twisted by nylon fiber 18 and spandex fiber 20, and the outer yarn includes PTT fiber 21. The outer yarn is parallel to the outside of the core yarn and twisted together with the core yarn. The nylon fiber 18, spandex fiber 20 and PTT fiber 21 are used to increase the elastic performance of the inner layer 13, and the PTT fiber 21 is arranged on the outside of the elastic yarn. The soft feel and good dimensional stability of the PTT fiber 21 are used to increase the flexibility of the fabric, prevent the operator's hands from being injured by friction due to excessive hardness and roughness when winding or unfolding the fabric, and ensure that the fabric still maintains a stable size after being squeezed or stretched, thereby increasing the use effect.
[0028] A bundle of nylon fiber 18 and polypropylene fiber 19 are twisted to form waterproof yarn by a ring spinning machine, and the polypropylene fiber 19 is wound around the outside of the nylon fiber 18, and then a bundle of nylon fiber 18 and a bundle of spandex fiber 20 are twisted to form core yarn by a ring spinning machine, and PTT fiber 21 is wound around the outside of the core yarn as an outer yarn and the two are twisted to form elastic yarn, and then the outer layer 11 of the reinforced twill weave is woven by a water jet loom with the waterproof yarn as the raw material, and the inner layer 13 of the plain weave is woven by a water jet loom with the elastic yarn as the raw material, and then the rubber melt in the molten state is brushed onto the surface of the inner layer 13 by a coating machine, and a number of thin rods or yarns arranged at intervals are placed in the rubber melt, and then a number of rows of through holes 16 are opened on the surface of the outer layer 11 by a laser punching machine, and at the same time, the distance between two adjacent rows of through holes 16 is the same as that between two adjacent second drainage holes. The distances between the grooves 17 are equal, and then glue is applied to the surface of the rubber layer 12, and the outer layer 11 is covered on the surface of the rubber layer 12, and the positions of the outer layer 11 and the rubber layer 12 are positioned by a thin rod or yarn to ensure that the through hole 16 is relative to the position of the thin rod or yarn, and then the outer layer 11, the rubber layer 12 and the inner layer 13 are fixed, and then the rod or yarn is pulled out to form a second drainage groove 17 between the outer layer 11 and the rubber layer 12, and then a hot pressing molding machine is used to extrude the water guide surface 14 and the first drainage groove 15 on the surface of the outer layer 11, and the hot pressing molding machine is used to heat-melt the surface of the outer layer 11 and fill the gaps existing during weaving, thereby increasing the waterproof effect of the outer layer 11, and at the same time, the heat released by the hot pressing molding machine and the pressure applied to the outer layer 11 further increase the connection strength between the outer layer 11 and the rubber layer 12, and the preparation is completed after the outer layer 11, the rubber layer 12 and the inner layer 13 are cooled.
