[0016] In the figure: 1-wear-resistant layer, 2-antibacterial and deodorizing layer, 3-formaldehyde adsorption layer. DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Combination Figure 1 The present embodiment is described in detail. An antibacterial and deodorizing warp knitted fabric comprises: a wear-resistant layer 1, an antibacterial and deodorizing layer 2 and a formaldehyde adsorption layer 3 which are compounded in sequence; the wear-resistant layer 1 is a four-comb structure, and the yarn padding numbers of the four combs are,

[0019] GB1: 2-3 / 2-2 / 1-0 / 1-1 / / ;

[0020] GB2: 1-1 / 1-0 / 2-2 / 2-3 / / ;

[0021] GB3: 1-0 / 2-3 / 4-5 / 3-2 / / ;

[0022] GB4: 0-0 / 3-3 / 0-0 / 3-3 / / ;

[0023] The antibacterial and deodorizing layer 2 is formed by warp knitting tea fiber yarns; and the formaldehyde adsorption layer 3 is formed by warp knitting honeycomb bamboo charcoal fiber yarns.

[0024] Specifically, the wear-resistant layer 1, the antibacterial and deodorizing layer 2 and the formaldehyde adsorption layer 3 are compounded by a mesh hot-melt adhesive.

[0025] Tea fiber is a kind of viscose fiber with antibacterial and deodorizing functions made from natural antibacterial agents extracted from tea leaves - natural tea pigments, tea polyphenols and catechins. Tea fiber has good moisture absorption and air permeability, antibacterial and health care functions, can improve human microcirculation, and play an auxiliary role in the treatment of skin aging and cardiovascular diseases. It is widely used in household textiles.

[0026] The wood adhesives used in many sofas cannot do without formaldehyde in the production process, and the wood itself also contains formaldehyde. Indoor air is also easily polluted by formaldehyde from decoration materials. Therefore, the formaldehyde adsorption layer 3 is provided to make the antibacterial and deodorizing warp knitted fabric have a certain effect of purifying indoor air. The cross section of the honeycomb bamboo charcoal fiber is elliptical, the fiber is evenly distributed in the longitudinal direction, and there are also small particles adsorbed. These tiny particles increase the specific surface area and adsorption capacity of the fiber, which can achieve the effect of absorbing formaldehyde.

[0027] Furthermore, the GB1 is drawn in the order of one island-in-the-sea yarn and two nylon filaments; and the GB2 is drawn in the order of two nylon filaments and one island-in-the-sea yarn.

[0028] Furthermore, the specification of the sea island yarn is 75D / 36F, and the specification of the nylon filament is 50D / 24F.

[0029] Sea-island yarn is made by dispersing one polymer in another polymer. The dispersed phase is in an "island" state in the fiber cross section, and the matrix is ​​equivalent to the "sea". After being woven into the fabric, the "sea" component is dissolved through finishing to obtain ultrafine fibers.

[0030] Nylon filament is extremely durable, mainly due to its excellent wear resistance and high strength. Nylon's wear resistance is ten times that of cotton fiber and ten times that of dry viscose fiber. High strength is not only reflected in the dry state, but also in the wet state. Its strength remains quite high, which is basically the same as the dry strength. Blending with other yarns can improve the strength and wear resistance of the fabric. Compared with polyester, nylon has superior moisture absorption. Its warp knitted fabric as a sofa fabric helps regulate the user's body temperature and gives the user a more comfortable feeling in hot weather or humid environments.

[0031] Furthermore, the polyester bonded yarn is inserted into the GB3; and the polyester-nylon composite yarn is inserted into the GB4.

[0032] Furthermore, the fineness of the polyester bonded yarn is 93.3tex, and the specification of the polyester-nylon composite yarn is 75D / 36F×12P.

[0033] Specifically, the cross-section of the polyester-nylon composite yarn is in the shape of an orange segment, the segment part is polyester, and the part connecting the segments is nylon. The woven fabric is treated with alkali to decompose the nylon and split the polyester-nylon composite yarn to obtain ultrafine fibers.

[0034] Specifically, the polyester bonded yarn is a composite twisted yarn formed by using a hot-melt yarn as a core yarn and three-strand twisted polyester filaments as an outer yarn, which is twisted and heat-set to form a composite twisted yarn. The polyester bonded yarn has the advantages of high strength, wear resistance, softness, and smoothness, and is an ideal twisted yarn for weaving sofa fabrics.

[0035] The wear-resistant layer 1 utilizes ultrafine fibers and wear-resistant fibers, combined with a four-comb structure, to achieve a three-dimensional effect on the surface, with good wear resistance, and there are spaces between the stripes supported by ultrafine fibers, which has special compression softness.

[0036] 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.
