Description

Technical Field

[0001] The utility model relates to the technical field of textiles, and more specifically to a high-elastic tensile-resistant knitted fabric. Background Art

[0002] Fabrics are the main materials for making clothes that people wear daily. Existing fabrics are divided into knitted fabrics and woven fabrics. Knitted fabrics usually have a soft touch and good breathability, so they are often used to make underwear, leggings and other close-fitting clothing.

[0003] However, the weaving structure of knitted fabrics is usually loose, so the elastic recovery ability of knitted fabrics is poor. Clothes made of knitted fabrics will be stretched as the limbs move during daily wear, and cannot return to their original shape in time after stretching. They have poor shape retention, which makes clothes made of knitted fabrics easily lose elasticity and become loose and deformed as the number of times they are worn increases, affecting their service life.

[0004] Therefore, a new solution needs to be proposed to solve the problem of poor elastic recovery ability of knitted fabrics. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a high-elastic tensile-resistant knitted fabric, which achieves the purpose of enhancing the elasticity and elastic recovery ability of the knitted fabric through a new structural setting.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: the high-elastic tensile-resistant knitted fabric includes an elastic layer, a plurality of elastic sheets are symmetrically arranged on one side of the elastic layer along the length direction, the elastic layer is provided with a plurality of through holes arranged in an array, the elastic sheet is located between the through holes adjacent to each other along the length direction of the elastic layer, the elastic layer is provided with a plurality of tensile-resistant yarns that reciprocate between the plurality of through holes and the plurality of elastic sheets along the length direction, and a plurality of elastic parts are arranged at intervals on the peripheral wall of the tensile-resistant yarn along the length direction.

[0007] The utility model is further configured as follows: the tensile yarn is a slub yarn formed by twisting a first strand and a second strand, the first strand is twisted by spandex fiber, the second strand is twisted by nylon fiber, and the resilient member is a node of the slub yarn.

[0008] The utility model is further configured as follows: the resilient sheet is made by weaving high-elastic yarn through a double-threaded structure, the elastic layer is made by weaving high-elastic yarn through a transfer loop structure, and a plurality of through holes are integrally formed on the elastic layer through the transfer loop structure.

[0009] The utility model is further configured as follows: the high-elastic yarn is made by spirally winding a third strand of yarn on a first strand of yarn, and the third strand of yarn is twisted by wool fibers.

[0010] The utility model is further configured as follows: the elasticity and elastic recovery capacity of the first strand and the second strand are both greater than the elasticity and elastic recovery capacity of the third strand.

[0011] The utility model is further configured as follows: the horizontal density of the coils of the resilient sheet is set to 24 turns / 5 cm, the vertical density of the coils of the resilient sheet is set to 19 turns / 5 cm, and the weaving density of the resilient sheet is greater than the weaving density of the elastic layer.

[0012] The utility model is further configured that: the content of the first strands in the resilient sheet is greater than the content of the first strands in the elastic layer with the same width.

[0013] In summary, the utility model has the following beneficial effects: a plurality of through holes enable the elastic layer to obtain a greater stretching distance, the spandex fiber has higher elasticity and elastic recovery ability, so that the manufactured elastic layer has good shape retention, and a plurality of spring-back sheets and a plurality of tensile-resistant yarns can generate a greater rebound force after being stretched together with the elastic layer, thereby driving the elastic layer to quickly return to its original shape after stretching, so that the elastic layer is not easy to lose elasticity and relax and deform under frequent stretching, thereby improving the service life of the fabric, and at the same time, a plurality of spring-back sheets and a plurality of tensile-resistant yarns can disperse the tension on the elastic layer, thereby reducing the possibility of the elastic layer being broken and damaged due to a large tensile force.

[0020] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Embodiment: The high elastic tensile knitted fabric, such as Figure 1-Figure 5As shown, it includes an elastic layer 1, and the elastic layer 1 is provided with a plurality of through holes 3 arranged in an array. The plurality of through holes 3 enable the elastic layer 1 to obtain a larger stretching distance. The elastic layer 1 is made by feeding a high-elastic yarn 8 into a knitting machine and knitting it through a transfer loop organization. The plurality of through holes 3 are integrally formed on the elastic layer 1 through the transfer loop organization. The high-elastic yarn 8 is made by spirally winding a third strand 9 on a first strand 6 through a ring spinning process. The first strand 6 is twisted by a spandex fiber through a twisting machine. The spandex fiber has high elasticity and elastic recovery ability, so that the elastic layer 1 can quickly recover to its original shape after being stretched, and has good shape retention. The third strand 9 is twisted by a wool fiber through a twisting machine. The wool fiber has a soft and comfortable touch as well as strong moisture absorption and air permeability, so that the fabric can quickly absorb sweat generated by the skin when worn, thereby improving the comfort of the fabric when worn. At the same time, the wool fiber has good resilience and its elongation will increase after moisture absorption, further improving the stretching effect of the elastic layer 1.

[0022] like Figure 1 and Figure 5 As shown, the elastic layer 1 is symmetrically provided with a plurality of rectangular springback sheets 2 on one side along its length direction. The springback sheets 2 are formed by feeding high elastic yarn 8 into an air jet loom and weaving the high elastic yarn 8 into a base layer by a double thread structure and then cutting the base layer by a cutting machine. The springback sheets 2 woven by the double thread structure have high elasticity and elastic recovery ability. The horizontal density of the coils of the springback sheets 2 is set to 24 turns / 5 cm, and the vertical density of the coils of the springback sheets 2 is set to 19 turns / 5 cm. The elasticity and elastic recovery ability of the springback sheets 2 are further enhanced by increasing the weaving density.

[0023] like Figure 1-Figure 4 As shown, the elastic layer 1 is provided with a plurality of tensile yarns 4 which are reciprocatedly connected between a plurality of through holes 3 and a plurality of resilient sheets 2 along its length direction, and a plurality of resilient members 5 are arranged at intervals on the peripheral wall of the tensile yarn 4 along its length direction. The tensile yarn 4 is formed by twisting a first strand 6 and a second strand 7 through a fancy twisting machine, and the first strand 6 is wound around a designated area on the second strand 7 for multiple times by reducing the moving speed of the roller in the fancy twisting machine to form the resilient member 5. The resilient member 5 formed by multiple windings of spandex fiber has high elasticity and elastic recovery ability, so that the tensile yarn 4 can be quickly restored to its original state after being stretched by the tensile force of the plurality of resilient members 5, and the second strand 7 is twisted by nylon fiber through a twisting machine, and nylon fiber has strong tensile resistance. The tensile force on the elastic layer 1 can be dispersed through the plurality of resilient sheets 2 and the plurality of tensile yarns 4, thereby reducing the situation where the elastic layer 1 is broken and damaged due to a large tensile force.

[0024] like Figure 1-Figure 5As shown, the elastic sheet 2 is located between the through holes 3 adjacent to each other along the length direction of the elastic layer 1, and the air permeability of the fabric as a whole is enhanced by the through holes 3. The elasticity of the elastic layer 1 is prevented from decreasing after the through holes 3 are opened by the elastic sheets 2 located between the adjacent through holes 3 and the tensile yarns 4 connected between the elastic sheets 2 and the through holes 3. The content of the first strand 6 in the elastic sheet 2 is greater than the content of the first strand 6 in the elastic layer 1 with the same width, and the weaving density of the elastic sheet 2 is greater than the weaving density of the elastic layer 1, so that the elasticity and elastic recovery ability of the elastic sheet 2 are large. Regarding the elasticity and elastic recovery of the elastic layer 1, the elasticity and elastic recovery of the first strand 6 and the second strand 7 are greater than the elasticity and elastic recovery of the third strand 9, so that the elasticity and elastic recovery of the tensile yarn 4 are greater than the elasticity and elastic recovery of the elastic layer 1. After being stretched together with the elastic layer 1, a large elastic force can be generated by a plurality of elastic sheets 2 and a plurality of tensile yarns 4, thereby driving the elastic layer 1 to quickly return to its original shape after being stretched, so that the elastic layer 1 is not easy to lose elasticity and relax and deform under frequent stretching, thereby improving the service life of the fabric.

[0025] 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.
