Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glue-spraying cotton, in particular to a high-elasticity anti-static glue-spraying hard cotton. Background Art
[0002] Spray-bonded cotton, also known as spray-bonded cotton, is a type of nonwoven fabric. The principle of the formation of the spray-bonded cotton structure is to spray the adhesive on both sides of the fluffy fiber layer. Due to the certain pressure during spraying and the suction force during the vacuum absorption of the lower part, the adhesive can also penetrate into the inside of the fiber layer. The fiber layer after spraying the adhesive is then dried and cured, so that the intersections between the fibers are bonded, and the fibers that are not bonded to each other still have considerable freedom. At the same time, in the three-dimensional mesh structure, there are still many gaps containing air. Therefore, the fiber layer has a porous and highly fluffy warming effect, and is an important material for processing and manufacturing bedding such as mattresses and sleeping bags.
[0003] When the spray-bonded cotton is used to process and manufacture bedding such as mattresses and sleeping bags, it needs to have a smooth surface and a certain hardness to reduce the exposure of internal fibers and cause fuzzing; it also needs to have good elasticity to improve the comfort of the user; in addition, it is often rubbed during use and is prone to static electricity, so it also needs to have an anti-static function. Utility Model Content
[0004] The utility model aims to provide a high-elasticity anti-static glue-sprayed hard cotton, which aims to solve the problems raised in the above-mentioned background technology.
[0005] In order to solve the above technical problems, the purpose of the utility model is achieved as follows: a high-elasticity anti-static spray-coated hard cotton, comprising: a first hardness reinforcement net, an anti-static layer, a far-infrared layer, an elastic layer, an anti-mildew layer and a second hardness reinforcement net arranged in sequence; the first hardness reinforcement net, the anti-static layer, the far-infrared layer, the elastic layer, the anti-mildew layer and the second hardness reinforcement net are bonded by an adhesive; the far-infrared layer is a nano-graphene PLA far-infrared fiber layer; the elastic layer is a polyurethane elastomer; the first hardness reinforcement net and the second hardness reinforcement net are low-melting point polyester fiber filaments arranged in a criss-cross pattern; the surfaces of the first hardness reinforcement net and the second hardness reinforcement net are ironed to form a membrane-like surface with mesh holes.
[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the antistatic layer is an antistatic polyester fiber layer.
[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the fineness of the antistatic polyester fiber is 50-80D.
[0008] On the basis of the above solution and as a preferred solution of the above solution: the antistatic layer is a cowhide fiber layer.
[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the anti-mildew layer is an antibacterial and anti-mildew polypropylene fiber layer.

[0011] Figure 1 This is a schematic diagram of the structure of the high-elasticity anti-static glue-spraying hard cotton involved in the utility model;
[0012] In the figure: 1-first hardness reinforcement net, 2-antistatic layer, 3-far infrared layer, 4-elastic layer, 5-anti-mildew layer, 6-second hardness reinforcement net. DETAILED DESCRIPTION
[0013] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0014] Embodiment 1
[0015] Combination Figure 1 This embodiment is described in detail. A high-elastic antistatic spray-coated hard cotton comprises: a first hardness reinforcement net 1, an antistatic layer 2, a far infrared layer 3, an elastic layer 4, an anti-mildew layer 5 and a second hardness reinforcement net 6 arranged in sequence; the first hardness reinforcement net 1, the antistatic layer 2, the far infrared layer 3, the elastic layer 4, the anti-mildew layer 5 and the second hardness reinforcement net 6 are bonded by an adhesive; the far infrared layer 3 is a nanographene PLA far infrared fiber layer; the elastic layer 4 is a polyurethane elastomer; the first hardness reinforcement net 1 and the second hardness reinforcement net 6 are low-melting point polyester fiber filaments arranged in a criss-cross pattern; the surfaces of the first hardness reinforcement net 1 and the second hardness reinforcement net 6 are ironed to form a film-like surface with mesh holes. Specifically, the fineness of the low-melting point polyester fiber filament is 50-65D, the distance between two adjacent low-melting point polyester fiber filaments in the horizontal direction is between 1-1.5cm, and the distance between two adjacent low-melting point polyester fiber filaments in the vertical direction is between 1-1.5cm.
[0016] When the surfaces of the first hardness reinforcement net 1 and the second hardness reinforcement net 6 are ironed, the low-melting-point polyester fiber filaments will melt and bond to the fibers of the antistatic layer 2 and the anti-mildew layer 5 respectively, reducing the fluff on the surface of the spray-coated hard cotton and forming a harder film-like surface with mesh holes.
[0017] The nanographene PLA far-infrared fiber is made of nanographene and fully biodegradable polylactic acid as raw materials through melt spinning. As a kind of single-atomic-layer two-dimensional crystal, nanographene has a unique structure that gives it excellent physical and chemical properties. Graphene is both a far-infrared absorber and a good radiator, and has the function of far-infrared heat storage and energy storage. PLA is a biodegradable material with no pollution in the preparation process, and has good biocompatibility and mechanical properties. It is an excellent green fiber raw material. The nanographene PLA far-infrared fiber layer can reflect the far-infrared waves of thermal radiation generated by the human body, and radiate far-infrared rays of a specific wavelength to the human body to achieve the effect of heat storage and energy storage.
[0018] The polyurethane elastomer has excellent comprehensive properties, high strength and elasticity, higher bearing capacity than other elastomers at the same hardness, excellent toughness and fatigue resistance, and can make the spray-coated hard cotton have higher elasticity, that is, compression recovery.
[0019] Furthermore, the antistatic layer 2 is an antistatic polyester fiber layer.
[0020] Furthermore, the fineness of the antistatic polyester fiber is 50-80D.
[0021] The antistatic polyester fiber is a modified polyester fiber whose specific resistance is reduced from 1010-1011 ohm·m of conventional polyester to 106-108 ohm·m after antistatic modification, and is prepared by adding a high temperature resistant antistatic agent during polymerization, preparing slices and then melt spinning. The antistatic polyester fiber has the advantages of long-lasting antistatic property and good washability.
[0022] Further, the anti-mildew layer 5 is an antibacterial and anti-mildew polypropylene fiber layer. The antibacterial and anti-mildew polypropylene fiber is prepared by twin-screw co-extrusion and single-screw spinning process using low-toxic and high-temperature resistant thiophanate-methyl and nano zinc oxide as antibacterial and anti-mildew agents. Thiabendazole is an efficient, spectral, and universal bactericide. It is also an oral agent approved by the U.S. Food and Drug Administration for antifungal and antiparasitic treatment and an agent used in combination with auxiliary anti-angiogenesis treatment. It is also used as a food preservative and has the characteristics of low toxicity and high heat resistance. Nano zinc oxide has the characteristics of high thermal stability, good antibacterial and antibacterial, deodorizing and anti-mildew, and low price. Thiabendazole shows good antibacterial effect on Escherichia coli, and nano zinc oxide shows good antibacterial performance on Staphylococcus aureus. Therefore, the fiber prepared by blending with polypropylene has good antibacterial and anti-mildew performance.
[0023] Embodiment 2
[0024] The difference from the first embodiment is that the antistatic layer 2 is a cowhide fiber layer. The cowhide fiber is made of leather waste and is prepared by cotton spinning equipment. The cowhide fiber has good antistatic performance. On the one hand, it is because the cowhide fiber has a high moisture regain, good moisture absorption performance, and improved conductivity; on the other hand, it is because the fiber has a high oil content, a smooth surface, a small number of curls, and relatively small friction between fibers.
[0025] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
