BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic structural diagram of the diamond lattice warp knitted fabric for automotive ceiling involved in the present utility model;
[0012] In the figure: 1 - diamond lattice jacquard layer, 2 - antibacterial and mildew - proof layer, 3 - sound insulation layer. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0013] The present utility model will be further described below in conjunction with the drawings and specific embodiments.
[0014] In conjunction with Figure 1 A diamond lattice warp knitted fabric for automotive ceiling, comprising: a diamond lattice jacquard layer 1, an antibacterial and mildew - proof layer 2, and a sound insulation layer 3 which are sequentially compounded; the diamond lattice jacquard layer 1 is warp knitted from cationic polyester filaments and antibacterial polyamide filaments, and the cationic polyester filaments and antibacterial polyamide filaments are arranged in the order of 2:2; the antibacterial and mildew - proof layer 2 is warp knitted from antibacterial and mildew - proof yarns; the sound insulation layer 3 is warp knitted from basalt core - spun yarns; the basalt core - spun yarns include a core yarn and an outer wrapping yarn, the core yarn is basalt fiber filaments, and the outer wrapping yarn is a polyester - cotton blended yarn. Specifically, the polyester - cotton blended yarn is a 65 / 35 polyester - cotton blended yarn with a fixed quantity of 5.89 g / 10m. The diamond lattice jacquard layer 1, the antibacterial and mildew - proof layer 2, and the sound insulation layer 3 are compounded through a net - shaped hot melt adhesive.
[0015] Furthermore, the fineness of the cationic polyester filament is 70D - 100D, and the fineness of the antibacterial polyamide filament is 70D - 100D. The cationic polyester filament, also known as cation-dyeable polyester, belongs to modified polyester. It is a polyester product spun by introducing dimethyl isophthalate with a polar group SO3Na into polyester chips. Its appearance is indistinguishable from that of ordinary polyester filaments. Due to ionic modification, the fiber can be dyed with cationic dyes at 110°C. The antibacterial polyamide fiber filament is made by mixing 5% of the layered nano-silver antibacterial material into the masterbatch chips of polyamide 6 and using the blend spinning technology, which can prevent the generation of peculiar smells and has a persistent antibacterial function. The diamond lattice jacquard layer 1 is based on the dyeing characteristics of the cationic polyester filament and combines the 2:2 arrangement order of the cationic polyester filament and the antibacterial polyamide filament. It is woven into a diamond lattice jacquard pattern using a four-bar warp knitting machine. After warp knitting and then dyeing, a unique pattern style can be achieved, which can visually display the appearance form of the ceiling to passengers.
[0016] Furthermore, the antibacterial and mildew-proof yarn is an antibacterial, mildew-proof and formaldehyde-removing multi-functional viscose fiber yarn. The antibacterial, mildew-proof and formaldehyde-removing multi-functional viscose fiber is prepared by blending and spinning with viscose spinning solution by adding wild chrysanthemum, coptis and zeolite micropowder suspension in mass ratios of 3.0%, 4.0% and 6.0% of methyl cellulose respectively, and sweet orange essential oil microcapsules in a volume ratio of 1.5% of the spinning solution. Plant traditional Chinese medicine contains rich active substances and has good antibacterial and mildew-proof functions. Extracts of coptis and wild chrysanthemum and sweet orange essential oil have good antibacterial and mildew-proof properties. Zeolite powder has good adsorption properties and is a good substrate for the formaldehyde adsorption functional agent. The antibacterial rate of the antibacterial, mildew-proof and formaldehyde-removing multi-functional viscose fiber against Staphylococcus aureus is 97.04%, the mildew-proof performance reaches grade 0, and the formaldehyde removal rate reaches 60.88%. After 20 times of washing, the antibacterial rate of the antibacterial, mildew-proof and formaldehyde-removing multi-functional viscose fiber against Staphylococcus aureus is 84.87%, the mildew-proof function can still reach grade 0, and the formaldehyde removal rate reaches 65.45% after 10 times of washing.
[0017] Furthermore, the fineness of the basalt fiber filament is 16.5tex / 200f. Basalt fiber is sourced from nature, can be naturally degraded and continuously recycled, and has many excellent properties such as high sound absorption coefficient, high strength, high modulus, fireproof and flame retardant, and resistance to ultraviolet light, and has a low cost. It is a green high-performance fiber.
[0018] Furthermore, the thickness of the sound insulation layer 3 is 3 - 5mm. When the sound insulation layer 3 has a certain thickness, it can enhance the sound absorption performance of the fabric, play a role in sound absorption and noise reduction, and block the noise from the car roof from entering the car.
[0019] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in this technical field based on the concept of the present utility model through logical analysis, reasoning, or limited experiments on the basis of the prior art shall fall within the protection scope determined by the claims.
