Description

Technical Field

[0001] This utility model relates to knitted fabrics, and more specifically, to composite knitted fabrics. Background Technology

[0002] Knitted fabric is a type of fabric formed by bending yarn into loops and interlocking them using knitting needles. It is commonly used in various types of clothing, such as T-shirts, sweaters, skirts, dresses, sweatshirts, gloves, and scarves. Its softness and elasticity make the clothing more form-fitting and comfortable.

[0003] In winter, people usually wear gloves to keep their hands warm and prevent frostbite. To ensure the warmth of gloves, most knitted fabrics used to make gloves are made of cotton fibers. Because cotton fibers have excellent warmth retention, gloves made of this fabric have good warmth retention. However, cotton fibers themselves have poor abrasion resistance, which makes the surface of gloves made of this fabric easily wear out when users wear them while working, resulting in a short service life for gloves made of this fabric.

[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 composite knitted fabric that has a good warmth retention effect and a long service life.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a composite knitted fabric, including a base layer and a wear-resistant layer composited on the surface of the base layer, wherein the surface of the base layer is provided with a plurality of raised strips, the raised strips being used to abut against the wear-resistant layer, a heat-insulating cavity is formed between adjacent raised strips, and a plurality of heat-insulating pile is provided on the surface of the raised strips.

[0007] The present invention is further configured such that: the wear-resistant layer is formed by weaving several wear-resistant yarns, the wear-resistant yarns include a yarn core and a covering yarn wrapped around the yarn core, the yarn core is formed by twisting several spandex fibers, and the covering yarn is formed by twisting several polyester fibers.

[0008] The present invention is further configured such that: the base layer includes comb GB1 yarn and comb GB2 yarn, the comb GB1 yarn forms a plain warp weave, the comb GB2 yarn forms a chain braid weave, and the plain warp weave and the chain braid weave overlap each other.

[0009] The present invention is further configured such that: the padding yarn number of the GB1 comb yarn is 1-0 / 1-2 / / full thread, and the padding yarn number of the GB2 comb yarn is 0-1 / / one thread and one empty.

[0010] The present invention is further configured such that: the combing GB2 yarn is formed by spirally winding two strands of separate yarn, and the warming fleece is held at the knot where the two strands of separate yarn are wound.

[0011] The present invention is further configured such that the warm fleece is made of cashmere fibers.

[0012] In summary, this utility model has the following beneficial effects: The wear-resistant layer in this utility model has good wear resistance, making the fabric as a whole more wear-resistant, thus making the fabric less prone to wear and extending its overall service life. The presence of the raised strips creates gaps between the base layer and the wear-resistant layer, and the gaps between adjacent raised strips form insulating cavities. Air entering and filling these cavities effectively reduces heat transfer, providing insulation and resulting in a better overall warmth retention. Furthermore, the insulating fleece on the surface of the raised strips has poor thermal conductivity due to its fiber structure, further reducing heat loss from the insulating cavities and ensuring the overall warmth retention of the fabric. Thus, through the combination of the base layer and the wear-resistant layer, the fabric achieves both good warmth retention and a long service life. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] See Figure 1-5As shown, the composite knitted fabric includes a base layer 1 and an abrasion-resistant layer 2 laminated on the surface of the base layer 1. Several raised strips 3 are provided on the surface of the base layer 1, and these strips 3 are designed to abut against the abrasion-resistant layer 2. Warm-insulating cavities 4 are formed between adjacent raised strips 3. Several warm-insulating fleece 5 are provided on the surface of the raised strips 3. When gloves are made using this composite knitted fabric, the base layer 1, as the inner layer, is in direct contact with the wearer's skin, while the abrasion-resistant layer 2 is in direct contact with the external environment. Because the abrasion-resistant layer 2 has good abrasion resistance, the fabric as a whole has good abrasion resistance, making it less prone to wear and tear, thus extending the overall lifespan of the fabric. The presence of the raised strips 3 creates gaps between the base layer 1 and the wear-resistant layer 2, and the gaps between adjacent raised strips 3 form a heat-insulating cavity 4. After air enters and fills the heat-insulating cavity 4, it can effectively reduce heat transfer and play a role in heat preservation, giving the fabric a good overall heat preservation effect. The heat-insulating fleece 5 on the surface of the raised strips 3 has poor thermal conductivity due to its fiber structure, which can reduce heat loss in the heat-insulating cavity 4, further ensuring the overall heat preservation effect of the fabric. Thus, through the cooperation of the base layer 1 and the wear-resistant layer 2, the fabric has a long service life while having good heat preservation.

[0022] See Figure 4 , Figure 6 As shown, the wear-resistant layer 2 is formed by weft knitting of several wear-resistant yarns 6, and the wear-resistant yarn 6 includes a yarn core 7 and a covering yarn 8 wrapped around the yarn core 7. The yarn core 7 is made of several spandex fibers twisted together, and the covering yarn 8 is made of several polyester fibers twisted together. Since spandex fibers have good elasticity, the wear-resistant yarn 6 has good elasticity, which in turn makes the wear-resistant layer 2 have good elasticity. Meanwhile, polyester fibers have good wear resistance, which in turn makes the wear-resistant layer 2 have good wear resistance.

[0023] See Figure 2-3 As shown, the base layer 1 includes guide bar GB1 yarn and guide bar GB2 yarn. The guide bar GB1 yarn forms a plain warp weave, and the guide bar GB2 yarn forms a chain braid weave. The plain warp weave and the chain braid weave overlap each other. The padding yarn number of the guide bar GB1 yarn is 1-0 / 1-2 / / full thread, and the padding yarn number of the guide bar GB2 yarn is 0-1 / / one thread and one gap. The guide bar GB1 yarn and the guide bar GB2 yarn are woven together to form the base layer 1. The chain braid weave and the plain warp weave are stacked to form a raised strip 3. The chain braid weave itself has good tensile strength, which is beneficial to improving the tensile strength of the base layer 1.

[0024] See Figure 5As shown, the combing GB2 yarn is made of two strands of ply yarn 9 spirally wound together. The insulating fleece 5 is held at the knot where the two strands of ply yarn 9 are wound together. When twisting the two strands of ply yarn 9, the two strands of ply yarn 9 are placed on the insulating fleece 5 for twisting, so that the insulating fleece 5 is held at the knot where the two strands of ply yarn 9 are wound together. Both ends of the insulating fleece 5 pass through the knot and are located on both sides of the combing GB2 yarn. The insulating fleece 5 is made of cashmere fiber. Cashmere fiber itself has good heat retention properties, so the insulating fleece 5 has a good effect, thereby further improving the overall warmth of the fabric. At the same time, since the insulating fleece 5 is formed on the surface of the convex strip 3, the air entering the insulating cavity 4 is hindered by the insulating fleece 5, and the flow rate becomes slower, thereby effectively reducing the rate of heat loss in the insulating cavity 4, thus ensuring the heat retention effect of the insulating cavity 4.

All technical solutions falling within the scope of this utility model's concept are protected.
