[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] Example 1

[0017] Combine Figure 1 This embodiment is described in detail. A functional composite warp knitted fabric comprises: a wear-resistant jacquard layer 1 and an antibacterial and thermal insulation layer 2; the wear-resistant jacquard layer 1 is warp-knitted by four combs GB1, GB2, GB3, and GB4; island-in-sea yarns and nylon fiber filaments are inserted into both GB1 and GB2, and the yarns in GB1 are arranged in the order of one island-in-sea yarn and two nylon fiber filaments, and the yarns in GB2 are arranged in the order of two nylon fiber filaments and one island-in-sea yarn; the antibacterial and thermal insulation layer 2 is warp-knitted by antibacterial yarns and thermal insulation yarns, and the antibacterial yarns and thermal insulation yarns are arranged in the order of 2:2. Specifically, the yarn inlay numbers of the four combing bars GB1, GB2, GB3, and GB4 are: GB1: 2-3 / 2-2 / 1-0 / 1-1 / / , GB2: 1-1 / 1-0 / 2-2 / 2-3 / / , GB3: 1-0 / 2-3 / 4-5 / 3-2 / / , GB4: 0-0 / 3-3 / 0-0 / 3-3 / / . The wear-resistant jacquard layer 1 and the antibacterial thermal insulation layer 2 are laminated by dot-shaped hot melt adhesive.

[0018] Furthermore, the specifications of the island-in-the-sea yarn are 75D / 36F, and the specifications of the nylon fiber filament are 50D / 24F. Island-in-the-sea yarn is a type of island-in-the-sea microfiber, which is made by dispersing one polymer in another. The dispersed phase in the fiber cross-section forms an "island" state, while the matrix is equivalent to the "sea". The sea component is finally dissolved through fabric finishing to obtain the microfiber, giving the fabric a soft luster and a plump and delicate surface.

[0019] Furthermore, 75D / 36F nylon-polyester composite yarn is inserted into GB3. Specifically, the cross-section of the nylon-polyester composite yarn is a segmented orange segment, where the segmented segments are polyester and the segmented segments are nylon. After finishing the fabric, the segmented segments can be split to obtain ultrafine fibers, resulting in a fluffy and soft fabric.

[0020] Furthermore, 75D / 144F nylon fiber filaments are inserted into the GB4.

[0021] The wear-resistant jacquard layer 1 is made of composite microfiber and nylon fiber, fully utilizing the characteristics of microfiber and nylon, combined with warp knitting technology, and woven with four combs to obtain a striped appearance with a three-dimensional effect on the surface. There is space supported by microfibers between the stripes, which has a microclimate adjustment ability with special compression performance. The nylon fiber filament can enhance the wear resistance of the fabric.

[0022] Furthermore, the antibacterial yarn is a blend of viscose-based apocynum venetum and viscose compact yarn, with a fineness of 14.69 tex. Specifically, the blend ratio of viscose-based apocynum venetum to viscose blended yarn is 30:70. Apocynum venetum fiber, also known as wild hemp and zeqi hemp, has a long history and a wide range of therapeutic benefits, including antibacterial, antihypertensive, antiasthmatic, lipid-lowering, far-infrared thermal insulation, and UV protection. Viscose-based apocynum venetum fiber is produced by spinning a composite of apocynum venetum and viscose, and exhibits excellent hand feel and yarn quality.

[0023] Furthermore, the thermal insulation yarn is a viscose-based wool protein and combed cotton compact-spun blended yarn, with a fineness of 14.62 tex. Specifically, the blend ratio of the viscose-based wool protein and combed cotton compact-spun blended yarn is 60:40. Viscose-based wool protein fiber is formed by spinning wool protein and viscose, has a C-shaped hollow cross-section, a soft feel, is rich in amino acids, and has a high hygroscopic calorific value.

[0024] The antibacterial and thermal insulation layer 2 has antibacterial properties due to the presence of viscose-based apocynum flax fibers. The presence of viscose-based wool protein fibers enhances the antibacterial properties, moisture absorption, heat preservation, and antistatic properties of the fabric. The combed cotton makes the fabric soft, moisture-absorbing, breathable, and comfortable to wear. Therefore, the antibacterial and thermal insulation layer 2 has antibacterial, moisture-absorbing, heat preservation, and antistatic properties. When the clothing made of the functional composite warp knitted fabric is worn, one side of the antibacterial and thermal insulation layer 2 is close to the human body.

[0025] Example 2

[0026] Combine Figure 2 This embodiment is described in detail. Based on the first embodiment, a reinforced antibacterial layer 3 is provided between the wear-resistant jacquard layer 1 and the antibacterial and thermal insulation layer 2. This reinforced antibacterial layer 3 is warp-knitted with polylactic acid fiber antibacterial composite yarn. The provision of this reinforced antibacterial layer 3 further enhances the overall antibacterial properties of the functional composite warp-knitted fabric.

[0027] Specifically, the polylactic acid fiber antibacterial composite yarn is made by using a narrow-slot negative pressure hollow roller condensing spinning device in the spinning process, so that a PLA / PHBV filament wraps two PLA coarse yarns under the action of twist (Z twist). The linear density of the polylactic acid fiber antibacterial composite yarn is 18.5tex.

[0028] PLA / PHBV filament is a blend of PLA and PHBV. PHBV is an aliphatic polyester synthesized by microorganisms. It is biodegradable and biocompatible. Produced by bacteria, it can be digested by bacteria and completely decomposed into carbon dioxide, water, and biomass in soil or composting conditions, without causing environmental pollution. By leveraging the antimicrobial properties of PLA and the biocompatibility of PHBV, the polylactic acid fiber antibacterial composite yarn is endowed with certain antibacterial properties. The polylactic acid fiber antibacterial composite yarn exhibits an inhibition rate of over 70% against Escherichia coli, Staphylococcus aureus, and Candida albicans, demonstrating excellent antibacterial properties.

[0029] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
