[0002] At present, the mainstream physiological products on the market are mainly disposable sanitary napkins and tampons. This type of disposable products can meet the needs of women in special periods. They are simple to use, easy to change, and have strong absorption capacity. However, in the long run, the cost of disposable products is high, and some disposable products contain some chemicals that threaten human health. At the same time, the use and disposal of a large number of disposable sanitary products will generate a large amount of garbage, which has a great negative impact on the environment. Therefore, in order to alleviate the pressure of disposable products on the environment, some manufacturers have begun to develop and produce reusable sanitary products. In the prior art, reusable sanitary products are mostly made of the superposition of several simple fabrics, which can only meet the small amount of demand in the early stage of the physiological period, cannot absorb a large amount of liquid, are prone to reverse osmosis, and are prone to breeding bacteria, which is not conducive to health.

[0025] The present application embodiment provides a fabric, such as Figure 1 As shown, the fabric includes a layer, b layer, c layer and d layer arranged in sequence; the a layer, b layer, c layer and d layer are fixed together by sewing or mechanical bonding.

[0026] The a layer is a double-sided fabric, that is, the a layer includes a surface layer 1 and an inner layer 2, and the surface layer 1 and the inner layer 2 are both woven from yarns, the number of interlacing points of the yarns in a unit cycle of the surface layer 1 is less than the number of interlacing points of the yarns in a unit cycle of the inner layer 2, and the number of yarn monofilaments used to weave the surface layer 1 is less than the number of yarn monofilaments used to weave the inner layer 2. Such a setting can form a capillary differential effect between the surface layer 1 and the inner layer 2, thereby enabling the liquid to achieve a unidirectional transfer effect from the surface layer 1 to the inner layer 2 in the a layer, avoiding the situation of back seepage. The yarn used to weave the surface layer 1 is a yarn containing one or more of the combined components of motherwort, wormwood, lavender, silver ions, copper ions, zinc ions or graphene. The yarn containing the above-mentioned components can effectively improve the antibacterial effect of the surface layer 1.

[0027] The two opposite sides of the b layer are provided with a terry layer 3, and the terry layer 3 is woven with high-loft yarn. The terry layer includes a plurality of terry loops, and the height of the terry loops is 0.1 mm to 5 mm. The thickness of the b layer is 0.2 mm to 10 mm. In the actual application process, the technicians in this field can select the specific thickness of the terry layer 3 and the b layer according to the actual needs.

[0028] The c layer includes a warp knitted mesh fabric layer 4 and a waterproof breathable membrane layer 5 which are sequentially arranged in a direction away from the b layer, and the warp knitted mesh fabric layer 4 and the waterproof breathable membrane layer 5 are bonded together.

[0029] The d layer is a skin-friendly outer layer 6, and the d layer is woven from yarn containing one or any two or more components of cotton, lyocell fiber, tencel fiber or polyurethane fiber.

[0030] The preparation method / process of the above-mentioned fabric is briefly described as follows:

[0031] Preparation of layer a:

[0032] ①Raw material selection and interlacing point design

[0033] The yarn used for surface layer 1 and connection is: 75D-36F-DTY graphene PET,

[0034] The yarn used for the inner layer 2 is: 75D-144F-DTYPET

[0035] The number of interlacing points of the surface layer 1 is 2 per cycle, and the number of interlacing points of the inner layer 2 is 4 per cycle. The yarn F number (number of monofilaments) used in the surface layer 1 is less than the yarn F number used in the inner layer 2, which can form a differential effect. The liquid diffuses along the surface 1 to the inner layer 2. The inner layer 2 has many interlacing points, and the liquid has an obvious wicking effect under the pressure formed by the interlacing points, and diffuses faster. Therefore, the liquid is easier to diffuse in the inner layer. The difference in F number and interlacing point between the surface layer 1 and the inner layer 2 can ensure that the surface of the a layer is dry during use, and the liquid diffuses quickly in the inner layer 2. At the same time, the use of graphene PET in the surface layer 1 has antibacterial and antibacterial effects, which can improve the physiological health of the user.

[0036] ② Weaving on the machine: Using 24G30-inch weft knitting double-sided round edge machine, 75D-36F-DTY graphene PET adopts a combination of looping, tucking and floating line weaving to form a mesh on the surface and also play a connecting role. 75D-144F-DTYPET adopts full looping weaving.
