BRIEF DESCRIPTION OF DRAWINGS
[0011] Figure 1 A structure diagram of the elastic antibacterial fabric is shown in the utility model.
[0012] In the drawing: 1, moisture-absorbing and heat-generating layer; 2, antibacterial reinforcing layer; 3, warmth-keeping layer; and 4, point-shaped hot melt type PU glue. DETAILED DESCRIPTION
[0013] The utility model is further described below in combination with the drawings and specific embodiments.
[0014] In combination with Figure 1 The elastic antibacterial fabric is described in detail as follows: a moisture-absorbing and heat-generating layer 1, an antibacterial reinforcing layer 2 and a warmth-keeping layer 3 are sequentially arranged; the moisture-absorbing and heat-generating layer 1, the antibacterial reinforcing layer 2 and the warmth-keeping layer 3 are compounded by point-shaped hot melt type PU glue 4 arranged in an array; the moisture-absorbing and heat-generating layer 1 is warp-knitted by two GB1 and GB2 combing bars; moisture-absorbing and heat-generating elastic yarns are inserted into the GB1; first antibacterial elastic yarns are inserted into the GB2; the GB1 and the GB2 have the following gage numbers: GB1: 1-0 / 2-3 / / , and GB2: 1-2 / 1-0 / / ; the antibacterial reinforcing layer 2 is warp-knitted by second antibacterial elastic yarns; and the warmth-keeping layer 3 is warp-knitted by warmth-keeping elastic yarns.
[0015] The point-shaped hot melt type PU glue 4 arranged in an array not only can compound each layer of the fabric together, but also has gaps between adjacent point-shaped hot melt type PU glues 4, so as to ensure the elasticity of the fabric as a whole.
[0016] Further, the moisture-absorbing and heat-generating elastic yarn is Porel moisture-absorbing and heat-generating spandex core-spun yarn. Specifically, the Porel moisture-absorbing and heat-generating spandex core-spun yarn is spun by adopting ring spinning process with Porel / viscose 40 / 60 blended yarn as outer wrapping fiber and spandex filament as core yarn. The moisture-conducting capacity of Porel fiber is similar to that of Coolbst moisture-absorbing and sweat-releasing fiber, superior to that of PTT and cotton, and the fiber has good air permeability and moisture permeability, low thermal conductivity, and good moisture-absorbing and air-permeating, warm-keeping and heat-storing properties due to the introduction of hydrophilic groups and flexible groups in the spinning process. The elastic yarn formed by wrapping Porel / viscose 40 / 60 blended yarn around spandex filament as core yarn has good moisture-absorbing and heat-generating effect and excellent elasticity.
[0017] Further, the first bacteriostatic elastic yarn comprises a core yarn and a wrapping yarn, and the wrapping yarn is spirally wrapped outside the core yarn; the core yarn is PBT filament, and the wrapping yarn is cow horn fiber / cocoon protein fiber / Aircell fiber blended yarn. Specifically, the cow horn fiber / cocoon protein fiber / Aircell fiber blended yarn is cow horn fiber / cocoon protein fiber / Aircell fiber 35 / 35 / 30 blended yarn. The cow horn fiber is a natural fiber with strong antibacterial ability, and the antibacterial ability against Staphylococcus aureus reaches 99%; the cocoon protein fiber is as smooth as mulberry silk, soft like cashmere, and good in skin friendliness; the Aircell fiber is a functional and durable multifunctional modified polyester fiber, which can release negative ions, has the functions of promoting metabolism, easy sleep, soothing nerves, relieving inflammation and pain, and has the functions of antibiosis, health care and ultraviolet protection. The moisture conductivity and air permeability of the Aircell fiber are higher than those of ordinary polyester, and the Aircell fiber has the softness and comfort of cotton, natural and soft luster, and good affinity. The PBT filament has high elastic recovery rate, and in general, the elastic recovery rate can reach more than 90% within a small range of tensile deformation. The use of PBT filament as core yarn can not only give the yarn good elasticity, but also give the yarn the functions of outer wrapping yarn.
[0018] Further, the second bacteriostatic elastic yarn has PBT filament as core and spirally wrapped bacteriostatic and deodorizing hemp pulp fiber blended yarn outside. Specifically, the bacteriostatic and deodorizing hemp pulp fiber blended yarn is cotton / deodorizing hemp pulp fiber 50 / 50 blended yarn. The deodorizing hemp pulp fiber is a regenerated cellulose fiber produced by mixing deodorizing agent into pulp made of hemp stalk, jute, red jute and other hemp plants, and has the functions of natural antibiosis, mildew resistance, mite killing and mite repelling. The bacteriostatic and deodorizing hemp pulp fiber blended yarn not only retains the functions of bacteriostasis, moisture absorption and sweat release of hemp fibers, but also inherits the comfortable and skin-friendly properties of cotton and viscose regenerated cellulose fibers, and further has the deodorizing function.
[0019] Further, the warm elastic yarn takes PBT filament as a core, and the hollow polyester filament is spirally wound outside. The hollow polyester filament is a differentiated fiber obtained by modifying traditional polyester, the hollow structure of the fiber can reduce the mass of the fiber by 20% compared with common fibers, and can contain a large amount of static air, form a unique warm system, and make the fiber assembly more fluffy and better in warm property.
[0020] The preferred embodiments of the utility model are described in detail above. It should be understood that those skilled in the art can make many modifications and changes according to the conception of the utility model without creative labor. Therefore, any technical scheme obtained by logical analysis, reasoning or limited experiment on the basis of the prior art according to the conception of the utility model should be within the protection scope defined by the claims.
