[0002] Paper yarn is a new type of environmentally friendly yarn produced primarily from plant fibers using a process similar to papermaking. Its processing is simple and produces no harmful emissions. After use, the product is biodegradable and reusable. It boasts advantages such as moisture absorption and breathability, antibacterial and odor control, static electricity prevention, and natural environmental friendliness. It can be used to produce high-end T-shirts, antibacterial socks, and other textile products. Its breathability, sweat absorption, and quick-drying properties are superior to cotton fabrics, meeting current demands for green and healthy textiles. Knitted fabrics, due to their soft feel, are widely used in the clothing industry. However, single-layer knitted fabrics, due to their thinness, have shortcomings in warmth and other functionalities. How to apply paper yarn to knitted composite fabrics to achieve good warmth and functionality is a problem that needs to be solved. Utility Model Content

Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0012] Example 1 Combination Figure 1 This embodiment will be described in detail below. The composite knitted fabric involved in this embodiment includes a composite paper yarn knitted fabric layer 1 and an antibacterial and warm fabric layer 2. Specifically, it is composited using an EVA hot melt adhesive web film, and the porosity of the hot melt adhesive web film reaches 65%, with a weight of 5 grams per square meter.

[0013] The paper yarn knitted fabric layer 1 comprises GB1 and GB2. GB1 uses paper yarn composite yarn, and GB2 uses spandex filament yarn. The paper yarn composite yarn includes twisted antibacterial cotton yarn and paper yarn blended yarn. The paper yarn blended yarn can be paper yarn cotton blended yarn or paper yarn polyester blended yarn; in this embodiment, recycled paper yarn polyester blended yarn is selected. The padding yarn number for GB1 is 2-3 / 1-0 / / , and the padding yarn number for GB2 is 1-0 / 1-2 / / . The weight of the paper yarn knitted fabric layer 1 is 180 grams per square meter.

[0014] The antibacterial and warm fabric layer 2 is woven from antibacterial and warm yarns, specifically using a warp-plain weave with a weight of 120 grams per square meter. The antibacterial and warm yarns include twisted antibacterial nylon filaments and hollow nylon filaments. Specifically, the antibacterial nylon filaments are copper-modified antibacterial and anti-mite polyamide 6 filaments. Antibacterial and anti-mite PA6 chips are obtained by coating nano-spherical copper antibacterial agents with oleic acid, blending them with a polyamide 6 (PA6) matrix, extruding and granulating, and then melt spinning and melt composite spinning to obtain copper-modified antibacterial and anti-mite PA6 filaments. The hollow nylon filaments are also made of nylon 6, with the hollow portion accounting for 60% of the cross-sectional area.

[0015] The antibacterial performance of this embodiment was tested, and the inhibition rate against Escherichia coli reached 92% and the inhibition rate against Staphylococcus aureus reached 89%.

[0016] Example 2 Combination Figure 3 This embodiment will be described in detail below. The composite knitted fabric involved in this embodiment differs from that in Embodiment 1 in that a warp-knitted interlining weft fabric layer 3 is provided between the paper yarn knitted fabric layer 1 and the antibacterial and warm fabric layer 2. Because knitted fabrics are soft to the touch, they have shortcomings in shape retention. To improve the dimensional stability of the composite knitted fabric in both the warp and weft directions, the warp-knitted interlining weft fabric layer 3 is provided. Specifically, it is composited using EVA thermal molten lamination web film.

[0017] The warp-knitted fabric layer 3 includes a warp-knitted fabric 31, with weft yarns 32 and warp yarns 33, which do not participate in loop formation, arranged along the weft direction between the loops and extension threads of the warp-knitted fabric 31. The yarn used in the warp-knitted fabric 31 is hollow polyester filament; the weft yarns 32 and warp yarns 33 are nylon 6 monofilaments with a diameter of 0.1-0.12 mm.

[0018] Example 3 Combination Figure 4 This embodiment will be described in detail below. The composite knitted fabric involved in this embodiment differs from that in Embodiment Two in that: an anti-ultraviolet film layer 4 is laminated to the side of the paper yarn knitted fabric layer 1 away from the antibacterial and warm fabric layer 2; the anti-ultraviolet film 4 has breathable pores with a pore size of 0.1-10 micrometers. The anti-ultraviolet film layer is a transparent PVC film or a ceramic micropowder film. In this embodiment, a transparent PVC film with a thickness of 5 micrometers is selected.

[0019] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
