Description

Technical Field

[0001] This utility model relates to the field of fabric technology, and in particular to a shoe material fabric with a three-layer warp-knitted mesh. Background Technology

[0002] Foam is a material made by foaming plastic particles, typically used in the collar (heel area) and tongue of shoes to increase comfort. Due to its poor abrasion resistance and tear resistance, foam is usually not used on the outside but needs to be bonded to other materials. During the manufacturing process, self-adhesive is usually applied first (glue is applied and release paper is attached). The lining of shoe uppers covers a larger area, and conventional shoe linings require plastic foam, which pollutes the environment. Furthermore, it requires post-processing with glue and removing release paper before it can be used. The use of foam and glue, and the waste of release paper, significantly increase the environmental burden, hindering green and sustainable development and increasing time and labor costs. Therefore, there is an urgent need to develop a warp-knitted three-layer mesh fabric to replace shoe foam, reducing post-processing steps and environmental pollution. Utility Model Content

[0003] Therefore, to address the aforementioned problems, this utility model proposes a shoe material fabric with a three-layer warp-knitted mesh. This solves the technical problem of the poor environmental friendliness of existing foam used in shoe upper linings.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A shoe material fabric with a three-layer warp-knitted mesh includes a fabric body, which comprises a jacquard layer, a middle layer, and a bottom layer arranged sequentially from top to bottom. The middle layer is woven into a plain weave using polyester-spandex core-spun yarn. The jacquard layer uses a first polyester low-elasticity yarn, which is inserted into the middle layer to form a weft-insertion weave. The first polyester low-elasticity yarn is locked to the surface by the polyester-spandex core-spun yarn. The bottom layer is woven into a plain weave using a second polyester low-elasticity yarn and spandex. The middle layer and the bottom layer are connected by polyester monofilaments using a one-through-one-open warp-threading method.

[0006] Further:

[0007] The polyester-spandex core-spun yarn includes a core yarn and a covering yarn wrapped around the core yarn. The core yarn is 40D spandex, and the covering yarn is 75D polyester low-elasticity yarn.

[0008] The first polyester low-elastic yarn is made by plying two 300D polyester low-elastic yarns together. The first polyester low-elastic yarn is made by plying 300D / 96F polyester DTY yarn.

[0009] The polyester monofilament used is 30D / 1F polyester monofilament.

[0010] The second polyester low-elastic yarn in the bottom layer is made of polyester DTY75D / 36F lightweight mesh.

[0011] The spandex in the bottom layer is made of spandex 40D.

[0012] The fabric body has a transverse density of 12.2 wpc, a longitudinal density of 18 cpc, a tensile density of 16 cpc, and a weight of 347 g / m2.

[0013] The main body of the fabric is woven from seven combs: GB1, GB2, GB3, GB4, GB5, GB6, and GB7. The jacquard layer is woven from two combs: GB1 and GB2. The middle layer is woven from two combs: GB3 and GB4. The polyester monofilament comb is GB5. The bottom layer is woven from two combs: GB6 and GB7.

[0014] The yarn backing lengths for GB1 and GB2 are: (0-0 / 1-1)×2 / 2-2 / (3-3 / 2-2)×2 / 1-1 / / , the yarn backing length for GB3 is: 1-0 / 2-3 / / , the yarn backing length for GB4 is: 2-3 / 1-0 / / , the yarn backing length for GB5 is: 1-0-0-1 / 1-2-2-1 / / , the yarn backing length for GB6 is: 1-0 / 1-2 / / , and the yarn backing length for GB7 is: 1-2 / 1-0 / / .

[0015] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0016] This invention uses a plain weave structure made of polyester-spandex core-spun yarn. The yarn is fluffy and soft, resulting in a soft and smooth fabric that fits snugly against the foot. The spandex in the bottom layer has high resilience and shrinkage properties, enhancing the fabric's transverse and longitudinal shrinkage and making it denser and finer. A weft weave structure made of low-elastic polyester yarn is locked to the front of the fabric by the polyester-spandex core-spun yarn, creating a textured surface that increases friction between the foot and the fabric. Polyester monofilament fabric is used with a one-through-one-open warp threading method to padded yarns at both the front and back needle beds, connecting the two layers of fabric to form a stable three-layer mesh structure while maintaining the soft feel of the fabric. This replaces the foam in the shoe lining, making it more environmentally friendly.

[0017] Furthermore, the polyester-spandex core-spun yarn is formed by simultaneously stretching 75D polyester low-elasticity yarn and 40D spandex through a nozzle, and then forming a rhythmic network of dots through regular high-compressed air spraying. The spandex has a good covering effect, the yarn is fluffy and comfortable, and the woven fabric has a soft and smooth feel and fits the foot.

[0018] Furthermore, the first polyester low-elastic yarn is made by spinning two 300D polyester low-elastic yarns together. The yarn count is coarse, which can well form a textured surface, thereby enhancing the friction between the foot and the fabric. It has high fiber breaking strength and elastic modulus, moderate resilience, and excellent heat setting performance.

[0019] Furthermore, the second polyester low-elasticity yarn and spandex yarn used in the bottom layer are finer, resulting in a lightweight and soft upper that provides three-dimensional support and a comfortable, friction-adhesive fit. Attached Figure Description

[0029] refer to Figures 1 to 7 This utility model provides a shoe material fabric with a three-layer warp-knitted mesh, including a fabric body, which includes a jacquard layer 1, a middle layer 2 and a bottom layer 3 arranged sequentially from top to bottom.

[0030] The intermediate layer 2 is woven into a plain weave using polyester-spandex core-spun yarn. The polyester-spandex core-spun yarn includes a core yarn and a covering yarn wrapped around the core yarn. The core yarn is 40D spandex, and the covering yarn is 75D polyester low-elasticity yarn. The jacquard layer 1 uses a first polyester low-elasticity yarn, which is inserted into the intermediate layer 2 to form a weft-insertion weave. The first polyester low-elasticity yarn is locked to the surface by the polyester-spandex core-spun yarn. The first polyester low-elasticity yarn is formed by plying two 300D polyester low-elasticity yarns together. The first polyester low-elasticity yarn is a 300D / 96F heavy mesh polyester DTY plyed yarn. The bottom layer 3 is woven into a plain weave using a second polyester low-elasticity yarn and spandex. The second polyester low-elasticity yarn in the bottom layer 3 is a 75D / 36F light mesh polyester DTY, and the spandex in the bottom layer 3 is 40D spandex. The intermediate layer 2 and the bottom layer 3 are connected by a one-through-one-open threading method using polyester monofilaments, and the polyester monofilaments are 30D / 1F polyester monofilaments.

[0031] The aforementioned polyester-spandex core-spun yarn is formed by simultaneously stretching 75D polyester low-elasticity yarn and 40D spandex through a nozzle, and then forming rhythmic network points through regular high-compressed air spraying. The spandex has a good covering effect, the yarn is fluffy and comfortable, and the woven fabric has a soft and smooth feel, conforming to the foot.

[0032] The machine used in this embodiment is a 22ERD7 / 2-12EN double needle bed warp knitting machine manufactured by KARLMAYER, Germany. The fabric has a warp density of 12.2 wpc, a weft density of 18 cpc, a tension density of 16 cpc, and a weight of 347 g / m². 2 A total of seven combs were used in the weaving.
