Stretch resistant knit fabric

Abstract

This utility model discloses a tensile-resistant knitted fabric, relating to fabric technology. The key technical points are: it includes a base layer with ventilation holes, tensile strips, and low-elasticity strips. The tensile strips increase the strength of the base layer near the ventilation holes, effectively reducing deformation along the length direction due to gravity, thus preventing deformation. The low-elasticity strips, when the knitted fabric is pulled horizontally, transfer the tension to adjacent tensile strips, giving the fabric a certain resistance to deformation in the width direction as well, thereby improving the overall deformation resistance of the knitted fabric. Polyamine fibers have excellent tensile properties; using core yarns made by twisting polyamine fibers effectively ensures the tensile strength of the tensile yarn.

Description

Technical Field

[0001] This utility model relates to fabric technology, and more specifically, to tensile-resistant knitted fabrics. Background Technology

[0002] Knitted fabric is a fabric formed by bending one or more yarns into loops and interlocking them on a knitting machine. Common knitted fabrics can be divided into warp-knitted fabrics and weft-knitted fabrics according to the direction of yarn weaving. In current technology, warp-knitted fabrics are often used as raw materials for curtain fabrics.

[0003] In places where light blocking is not a major requirement, such as studies, the breathability of curtains is often more important. This means that the knitted fabric used to make curtains usually has more ventilation holes. Since curtains are usually quite long, they are also more affected by gravity. The knitted fabric with ventilation holes has a low weave density and is prone to deformation. Therefore, there is a need to develop a tensile-resistant knitted fabric. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide tensile-resistant knitted fabric.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tensile knitted fabric, including a base layer, wherein a plurality of air holes are provided on the base layer, and tensile strips are provided on both sides of the air holes on the base layer, wherein the tensile strips are arranged along the length direction of the base layer, and a plurality of low elastic strips arranged in a wavy shape are also provided on the base layer, wherein the left and right ends of one of the low elastic strips are respectively fixedly connected to two adjacent tensile strips.

[0006] The present invention is further configured such that: the base layer is woven from comb GB1 yarn and comb GB2 yarn to form a warp-knitted mesh structure, and the tensile strip is formed by tensile yarn threaded onto the base layer.

[0007] The present invention is further configured such that: the padding yarn number of the GB1 comb yarn is 1-3 / 3-4 / 3-1 / 1-0 / / one thread and two empty spaces, and the padding yarn number of the GB2 comb yarn is 3-1 / 1-0 / 1-3 / 3-4 / / one thread and two empty spaces.

[0008] The present invention is further configured such that: the diameter of the tensile yarn is greater than the diameter of the comb GB1 yarn, and the low elastic strip is formed by weft insertion of structural yarn on the base layer.

[0009] The present invention is further configured such that: the padding yarn number of the tensile yarn is 0-1 / 1-0 / / one thread and two empty, and the padding yarn number of the structural yarn is 0-0 / 4-4 / / one thread and one empty.

[0010] The present invention is further configured such that: the tensile yarn comprises, from the inside out, a core yarn, a wound yarn, and an outer wrapping yarn, wherein the twist of the wound yarn on the core yarn is 580 twists / meter to 620 twists / meter, and the twist of the outer wrapping yarn outside the wound yarn is 400 twists / meter to 420 twists / meter.

[0011] The present invention is further configured such that: the core yarn is made of several polyamide fibers twisted together, the winding yarn is made of several bamboo fibers twisted together, and the outer covering yarn is made of several polyester fibers twisted together.

[0012] In summary, this utility model has the following beneficial effects:

[0013] The ventilation holes allow air to exchange between the two sides of the base layer, ensuring the breathability of the knitted fabric. The tensile strips improve the strength of the base layer near the ventilation holes, effectively reducing the deformation of the base layer in the length direction due to gravity, making the base layer less prone to deformation. The low-elasticity strips transfer the tension to the adjacent tensile strips when the knitted fabric is pulled horizontally, giving the knitted fabric a certain degree of resistance to deformation in the width direction, thereby improving the overall resistance to deformation of the knitted fabric.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Tensile knitted fabrics, such as Figure 1As shown, the system includes a base layer 1 with several ventilation holes 2 and tensile strips 3 on both sides of the ventilation holes 2. The tensile strips 3 are arranged along the length of the base layer 1. The base layer 1 also has several low-elastic strips 4 arranged in a wavy shape. The left and right ends of one low-elastic strip 4 are fixedly connected to two adjacent tensile strips 3. The ventilation holes 2 allow air to pass through and exchange between the two sides of the base layer 1, ensuring the breathability of the knitted fabric. The tensile strips 3 increase the strength of the base layer 1 near the ventilation holes 2, effectively reducing the deformation of the base layer 1 in the length direction due to gravity, making the base layer 1 less prone to deformation. When the knitted fabric is pulled horizontally, the low-elastic strips 4 can transfer the tension to the adjacent tensile strips 3 in a timely manner, giving the knitted fabric a certain resistance to deformation in the width direction as well, thereby improving the overall resistance to deformation of the knitted fabric.

[0023] like Figures 2 to 5As shown, the base layer 1 is woven from GB1 and GB2 comb yarns to form a warp-knitted mesh structure. The tensile strip 3 is formed by tensile yarns threaded onto the base layer 1. The warp-knitted mesh structure allows the ventilation holes 2 to be directly woven from the GB1 and GB2 comb yarns, eliminating the need for subsequent hole drilling and improving the overall strength of the base layer 1 to a certain extent. The tensile strip 3 formed by tensile yarns threaded onto the base layer 1 ensures a high connection strength between the tensile yarns and the base layer 1, enabling the tensile yarns to effectively support the base layer 1 and reduce the impact of the tensile stress on the base layer 1. Due to the degree of deformation caused by gravity, the padding number of the GB1 guide yarn is 1-3 / 3-4 / 3-1 / 1-0 / / one thread with two gaps, and the padding number of the GB2 guide yarn is 3-1 / 1-0 / 1-3 / 3-4 / / one thread with two gaps. Specifically, both the GB1 and GB2 guide yarns are woven into a double-warp plain weave, and the GB1 and GB2 guide yarns are symmetrically padded. Ventilation holes 2 are formed at the knitting gaps of the GB1 and GB2 guide yarns. The symmetrically padded GB1 guide yarn... When the yarn and the GB2 comb yarn are under tension, the deformation is relatively uniform, making the base layer 1 less prone to skewing. The diameter of the tensile yarn is larger than that of the GB1 comb yarn, while the GB1 and GB2 comb yarns are of equal diameter. The thicker tensile yarn ensures its strength. The padding yarn of the tensile yarn is 0-1 / 1-0 / / one thread, two gaps. Specifically, the tensile yarn is woven into a chain structure on the base layer 1, resulting in more interlacing points between the tensile yarn and the GB1 and GB2 comb yarns, allowing the tensile yarn to better support the base layer. Layer 1 provides vertical support. The low-elastic strip 4 is formed by wefting structural yarn on the base layer 1. The padding yarn number of the structural yarn is 4-4 / 0-0 / / one through and one open. Specifically, the structural yarn is wefted across the entire width of the base layer 1 to form the low-elastic strip 4. The structural yarn crosses the ventilation hole 2 on the base layer 1 and forms interlacing points with the two adjacent tensile yarns. This allows the base layer 1 to directly transfer the horizontal force to the two adjacent tensile yarns through the structural yarn, reducing the deformation of the ventilation hole 2 in the horizontal direction and thus improving the overall tensile strength of the knitted fabric.

[0024] like Figure 6As shown, the tensile yarn comprises, from the inside out, a core yarn 5, a wound yarn 6, and an outer covering yarn 7. The core yarn 5 is made of several polyamide fibers twisted together, and the wound yarn 6 is made of several bamboo fibers twisted together. Polyamide fibers have excellent tensile strength, and the core yarn 5 made of polyamide fibers twisted together can effectively ensure the tensile strength of the tensile yarn. Bamboo fibers have good antibacterial properties, and the wound yarn 6 formed by twisting bamboo fibers twisted together can provide a certain antibacterial ability to the tensile yarn, reducing the possibility of bacterial growth on the knitted fabric. The outer covering yarn 7... The covering yarn 7 is made of several polyester fibers twisted together. Polyester fibers have good abrasion resistance. The outer covering yarn 7 made of polyester fibers twisted together can effectively protect the wound yarn 6. The twist of the wound yarn 6 on the core yarn 5 is 580 twists / meter to 620 twists / meter, and the twist of the outer covering yarn 7 outside the wound yarn 6 is 400 twists / meter to 420 twists / meter. This twist setting allows part of the wound yarn 6 to be exposed at the two adjacent knots of the outer covering yarn 7, which can ensure the antibacterial properties provided by the wound yarn 6 for the tensile yarn.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
