Description

Technical Field

[0001] This utility model relates to the field of textile technology, and more specifically, to a polyester knitted fabric. Background Technology

[0002] Fabric is the main material used to make clothing that people wear every day. It is mainly divided into knitted fabric and woven fabric. Knitted fabric is often woven with natural fibers as the main raw material. It has a breathable and comfortable feel and is widely used in the production of underwear, pantyhose, gloves, hats and other close-fitting clothing.

[0003] However, compared to woven fabrics, knitted fabrics have a looser weave structure, and the elasticity and abrasion resistance of natural fibers are relatively poor. This makes clothing made of knitted fabrics prone to wear and deformation with repeated wear, resulting in a shorter lifespan.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a polyester knitted fabric that improves wear resistance and shape retention while ensuring the comfort of wearing the knitted fabric through a new structural design.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a polyester knitted fabric, including a base layer, a plurality of abrasion-resistant strips I are provided on one side of the base layer, a plurality of abrasion-resistant strips II and a plurality of elastic strips are provided on the side of the base layer away from the abrasion-resistant strips I, the abrasion-resistant strips I and II are arranged opposite to each other on both sides of the base layer and form a breathable area on the surface of the base layer, the cross section of the breathable area is hexagonal, the breathable area is formed with a plurality of breathable holes by a burnout process, the plurality of abrasion-resistant strips II are arranged in an array along the weft direction of the base layer, and the plurality of elastic strips are arranged in an array along the warp direction of the base layer.

[0007] The present invention is further configured such that: the length of the wear-resistant strip II is the same as the width of the base layer, the length of the rebound strip is the same as the length of the base layer, and a plurality of the wear-resistant strip II and a plurality of rebound strips intersect perpendicularly.

[0008] The present invention is further configured such that: both the first wear-resistant strip and the second wear-resistant strip are sewn onto the base layer using shape-retaining yarn, and the elastic strip is fixed to the base layer by sewing the second wear-resistant strip together.

[0009] The present invention is further configured such that: the base layer is made by weaving breathable yarn with a rib knit, the loop density of the base layer is set to 27 loops / 5cm in the horizontal direction, and the loop density of the base layer is set to 22 loops / 5cm in the vertical direction.

[0010] The present invention is further configured such that: the rebound strip is made by weaving shape-retaining yarn through a rib structure, and the weaving density of the rebound strip is greater than the weaving density of the base layer.

[0011] The present invention is further configured such that: the breathable yarn is made by wrapping cotton fibers on polyester profiled fibers, and the plurality of breathable holes are formed by acid-dissolving the cotton fibers on the surface of the breathable yarn in the breathable area through a burnout process to increase the spacing between the yarns.

[0012] In summary, this utility model has the following beneficial effects: the abrasion-resistant strips I, II, and rebound strips formed by polyester fibers have strong abrasion resistance, while reducing the contact area between the base layer and the skin or other clothing, thereby reducing the wear of the base layer. The abrasion-resistant strips I and II enhance the resilience of the base layer in the warp direction, and the rebound strips increase the resilience of the base layer in the weft direction, allowing the base layer to quickly return to its original shape after stretching, thus achieving good shape retention. The ventilation holes ensure good breathability of the base layer while adding polyester fibers. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example: A polyester knitted fabric, such as Figures 1-5As shown, the base layer 1 includes a plurality of abrasion-resistant strips 1-2 on one side of the base layer 1 and a plurality of abrasion-resistant strips 2-3 on the side of the base layer 1 away from the abrasion-resistant strips 1-2. The abrasion-resistant strips 1-2 and abrasion-resistant strips 2-3 are arranged opposite each other on both sides of the base layer 1. The abrasion-resistant strips 1-2 and abrasion-resistant strips 2-3 are both sewn onto the base layer 1 by two shape-retaining yarns. The shape-retaining yarns are made by twisting multiple polyester filaments by a twisting machine. Polyester fibers have good elasticity and abrasion resistance. Through the abrasion-resistant strips 1-2 and abrasion-resistant strips 2-3, they can first come into contact with and rub against the skin or other clothing, thereby reducing the degree of wear on the base layer 1. The abrasion-resistant strips 1-2 and abrasion-resistant strips 2-3 are arranged in an array along the weft direction of the base layer 1. The abrasion-resistant strips 1-2 and abrasion-resistant strips 2-3 formed by polyester fibers have strong resilience, thereby enhancing the longitudinal resilience of the base layer 1.

[0021] like Figures 1-5 As shown, a plurality of elastic strips 4 are provided on the side of the base layer 1 away from the wear-resistant strip 2. The elastic strips 4 are arranged in an array along the warp direction of the base layer 1. The length of the wear-resistant strip 2 3 is the same as the width of the base layer 1, and the length of the elastic strips 4 is the same as the length of the base layer 1. The plurality of wear-resistant strips 2 3 and the plurality of elastic strips 4 intersect perpendicularly. The elastic strips 4 are sewn to the base layer 1 through the wear-resistant strips 2 3. The elastic strips 4 are cut from the greige fabric made by feeding shape-retaining yarn into a knitting machine and knitting it with a rib structure. The knitting density of the elastic strips 4 is greater than the knitting density of the base layer 1, so that the polyester fiber The elastic strips 4, made with a high weave density, have strong resilience. The arrangement of several elastic strips 4 enhances the lateral resilience of the base layer 1, allowing the several abrasion-resistant strips 1 2, abrasion-resistant strip 2 3, and elastic strips 4 to generate greater resilience in both the lateral and longitudinal directions when stretched together with the base layer 1. This drives the base layer 1 to quickly return to its original shape when the tension is removed, achieving good shape retention. The arrangement of several elastic strips 4 further reduces the basic friction area between the base layer 1 and the skin or other clothing, enabling the knitted fabric to be used in environments with frequent pulling and friction.

[0022] like Figure 1 As shown, the base layer 1 is made by feeding breathable yarn into a knitting machine and knitting it with a rib structure. The loop density of the base layer 1 is set to 27 loops / 5cm, and the loop density of the base layer 1 is set to 22 loops / 5cm. Increasing the knitting density of the base layer 1 can enhance the strength and stability of the structure. The breathable yarn is a core-spun yarn. The core of the breathable yarn is made of twisted polyester fiber, and the outer yarn of the breathable yarn is made of twisted cotton fiber. The breathable yarn is made by wrapping cotton fiber on polyester fiber through a ring spinning machine. Cotton fiber has better moisture absorption and breathability than polyester fiber, so the base layer 1 has good moisture absorption and breathability.

[0023] like Figure 1 and Figure 3As shown, several abrasion-resistant strips 1 (2) and 2 (3) enclose several breathable areas 5 on the surface of the base layer 1. The cross-section of the breathable area 5 is hexagonal. Several breathable holes 6 are formed in the breathable area 5 through a burnout process. The prepared acidic printing paste is printed on the surface of the base layer 1 according to the distribution and shape of the breathable area 5 through a printing machine. Because cotton fibers have poor acid resistance while polyester fibers have good acid resistance, the cotton fibers on the surface of the breathable yarn will undergo acid degradation due to the influence of the acidic printing paste. Therefore, the breathable yarn is degraded by acid degradation in the breathable area 5 through the burnout process. The cotton fibers on the surface of the air-blown yarn increase the spacing between the yarns, forming air pores 6. After the burnout process, the base layer 1 is thoroughly washed in a washing machine to remove excess printing paste and fiber residue. An appropriate amount of detergent can be added during washing to improve the washing effect. The air circulation effect on both sides of the base layer 1 is improved through several air pores 6, which further improves the breathability of the fabric. At the same time, the good air circulation effect can accelerate the moisture dissipation speed of the base layer 1, thereby keeping the fabric and skin dry and comfortable, ensuring the comfort of wearing the knitted fabric.
