Technical Field

The invention relates to the technical field of female sanitary products, in particular to an elastic spacing fabric sanitary towel.

Background

The sanitary towel is a daily product necessary for the female in the physiological period, is closely related to the physical and psychological health of the female, and the requirements of the female on the sanitary towel are higher and higher along with the improvement of the living standard of people. Most sanitary towels in the market at present mainly comprise a surface layer, an absorption core and a bottom layer, and are made of cotton, non-woven fabrics, paper pulp or high molecular polymers as main materials, in order to achieve a certain liquid absorption amount, the sanitary towels are generally thick, the air permeability is poor, bacteria are easy to breed in a moist environment in menstrual periods, various gynecological diseases are caused, and after a large amount of menstrual blood is absorbed by the paper pulp, faults can appear, layering and lump phenomena are caused, so that discomfort of a human body is caused, secondly most sanitary towels are lack of elasticity, deformation is easy to occur in the using process, side leakage is caused, clothes are soiled, normal clothes and mood of people are influenced, particularly in the moving process, existing elastic sanitary towels mostly adopt elastic separation edges and elastic protection walls, and the structure and the manufacturing process of the sanitary towels are complicated.

Disclosure of Invention

The invention aims to overcome the defects and shortcomings, and provides an elastic spacing fabric sanitary towel which has good air permeability, is not easy to deform, improves the use comfort of the sanitary towel in the movement process, has good structural integrity and can be integrally formed, and the whole sanitary towel is endowed with elasticity and pressure resistance.

In order to achieve the purpose, the technical solution of the invention is as follows:

an elastic spacing fabric sanitary towel comprises a knitted spacing fabric layer and a waterproof bottom film layer, wherein the spacing fabric layer also comprises a skin-friendly surface layer, a spacing absorption layer and a lower surface layer with an adhesive effect, the skin-friendly surface layer is made of one of cotton, silk, hemp, bamboo charcoal fiber, viscose, chitosan, sodium alginate, polylactic acid, polyethylene, polypropylene and terylene or other raw materials which are subjected to skin-friendly function finishing, the spacing absorption layer is made of high-water-absorption yarn or covering yarn which is high-water-absorption fiber, the high-water-absorption fiber or yarn can be one of high-water-absorption polyvinyl alcohol fiber, high-water-absorption polyacrylonitrile fiber, high-water-absorption polyacrylamide fiber, high-water-absorption polyacrylic acid fiber and pure alginate fiber, the core yarn of the covering yarn is made of one of cotton, silk, terylene, chinlon, viscose, polypropylene fiber and aramid fiber, the lower surface layer is composed of low-melting-point fibers, the raw material is one of ES fibers, low-melting-point terylene, low-melting-point polyethylene and low-melting-point polyamide, and the waterproof bottom film layer is connected with the low-melting-point fibers in the lower surface layer in a hot melting mode.

As a further scheme of the invention: the daily and night sanitary towel can be formed by adjusting the thickness of the spacing layer or the quantity of the spacing threads.

As a further scheme of the invention: the upper surface layer of the knitted spacer fabric can be a loose mesh, a mesh, small patterns and a jacquard structure, so that the rapid entering of menstrual blood is facilitated, skin rash caused by skin is prevented, the lower surface layer can be a compact structure, the better adhesion of the adhesive layer and the waterproof bottom film layer is facilitated, and the leakage of the menstrual blood can be prevented.

Compared with the prior art, the invention has the beneficial effects that:

the invention adopts the knitted spacer fabric as the surface layer and the absorption layer material, compared with the traditional sanitary towel which is made of cotton, non-woven fabric, paper pulp or high molecular polymer as the main material, the sanitary towel has larger compression-resistant elasticity in the thickness direction, when the sanitary towel is subjected to the compression load in the thickness direction, the spacer wires of the absorption layer are bent, so that the load is transferred to the periphery, the pressure is dispersed in a larger radius range, the compression load born by the local part of the sanitary towel is reduced, and after the pressure disappears, the deformation of the sanitary towel is quickly recovered due to the existence of the spacer fabric. Secondly, the sanitary towel has good air permeability, and the air permeability of the spacing fabric with the upper layer and the lower layer which are light and thin and have a loose mesh structure is generally 1578-2328 mm³/(mm²S) and the air permeability of the fabric with dense surface and large gram weight of the spacing filament is 420-1360 mm³/(mm²S) range, all have good breathability. Besides, the sanitary towel also has good moisture absorption and moisture conduction functions, the upper surface layer of the loose structure can enable menstrual blood to rapidly infiltrate, and then the menstrual blood is transferred to the other surface of the fabric through the capillary effect of the separation threads of the absorption layer and is absorbed by the super absorbent fibers. The traditional sanitary towel needs multilayer compounding, uses adhesive and the like, causes serious environmental pollution in the production process, the spacer fabric does not need compounding and chemical bonding, and the insole layer can be bonded by hot melt fibers on the lower surface layer of the spacer fabric and also does not need chemical bonding agent, and the sanitary towel can be used for sanitary towelThe sanitary napkin can be integrally formed, thereby greatly reducing the environmental pollution. In addition, 2 upper and lower surface layers of warp knitting spacer fabric link together through the spacer silk, and layering, fault, play are stuck together by the suppression, have good structural integrity.
