Technical Field

The invention relates to the technical field of baby sanitary products, in particular to an elastic spacer fabric diaper and an elastic spacer fabric diaper.

Background

With the improvement of living standard of people, the diaper and the diaper become necessary daily necessities for each family, most diapers and diapers in the market at present mainly comprise a non-permeable outer layer, a permeable inner layer and an absorption core body fixed between the non-permeable outer layer and the permeable inner layer, and is made of cotton, non-woven fabric, paper pulp or high molecular polymer as main material, has slow absorption speed, can absorb certain urine volume, has limited liquid absorption amount in order to meet certain air permeability, when the urine volume is large, the flatus of the infant is often in a humid environment due to untimely absorption, so as to cause erythra, and after the paper pulp absorbs a large amount of urine, the phenomena of fault, layering and lump rise can occur, which causes the discomfort of the baby, secondly, most diapers and diapers are easy to deform in the using process due to lack of elasticity, so that urine leakage is caused, clothes are soiled, and the baby mood is influenced, especially in the exercise process.

Disclosure of Invention

The invention aims to provide an elastic spacer fabric diaper and a diaper, which have good air permeability, give elasticity and pressure resistance to the whole diaper, are not easy to deform, improve the use comfort of the diaper and the diaper in the movement process, have good structural integrity and can be integrally formed.

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

an elastic spacer fabric diaper comprises a knitted spacer fabric layer and a waterproof bottom film layer, wherein the spacer fabric layer also comprises a skin-friendly surface layer, a spacer 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 spacer 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 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 quantity of the spacing wires or the thickness of the spacing layer can be adjusted by changing the tissue design for the diaper with different stages of urine volume.

As a further scheme of the invention: knitting spacer fabric upper epidermis can be for more loose mesh, little decorative pattern, merchant card jacquard weave structure, is favorable to the urine to get into fast, prevents that skin from producing diaper rash, and the lower epidermis can be closely knit structure, is favorable to bond line and waterproof basement membrane layer to adhere better, and can prevent the urine seepage.

A spacer fabric diaper comprises a spacer fabric diaper main body, a front waist, an elastic rear waist and side edge guards, the elastic spacer fabric diaper comprises the spacer fabric diaper main body, the front waist, the elastic rear waist and the side edge guards, the spacer fabric diaper main body comprises a knitted spacer fabric layer and a waterproof bottom film layer, the spacer fabric layer comprises a skin-friendly surface layer, a spacer 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 finished by skin-friendly function, the spacer absorption layer is made of high-water-absorption yarns or core-spun yarns which are high-water-absorption fibers, the high-water-absorption fibers or yarns can be high-water-absorption polyvinyl alcohol fibers, high-water-absorption polyacrylonitrile fibers, and the like, One of super absorbent polyacrylamide fiber, super absorbent polyacrylic fiber, pure alginate fiber, the core yarn raw materials of covering yarn is in one of cotton, silk, dacron, polyamide fibre, viscose, polypropylene fibre, aramid fiber, lower top layer comprises the low melting point fibre, and the raw materials is in one of ES fibre, low melting point dacron, low melting point polyethylene, low melting point polyamide, waterproof basement membrane layer through with lower bottom layer low melting point fibre hot melt connection, preceding waist, elasticity back are directly bonded with interval water repellent fabric layer after the arrangement, do not need waterproof basement membrane layer. The front waist, the elastic back waist and the side edge protection are manufactured separately, and the edge sealing of the diaper main body is completed through hot-pressing edge sealing or ultrasonic edge sealing in the later period.

As a further scheme of the invention: the quantity of the spacing filament or the thickness of the spacing layer can be adjusted by changing the tissue design for the diaper with different urine quantity.

As a further scheme of the invention: knitting spacer fabric upper epidermis can be for more loose mesh, little decorative pattern, merchant card jacquard weave structure, is favorable to the urine to get into fast, prevents that skin from producing diaper rash, and the lower epidermis can be closely knit structure, is favorable to bond line and waterproof basement membrane layer to adhere better, and can prevent the urine seepage.

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 diaper and the diaper which are made of cotton, non-woven fabric, paper pulp or high molecular polymer as main materials, the diaper and the diaper have larger compression resistance elasticity in the thickness direction, when the diaper/the diaper is subjected to compression load in the thickness direction, the spacer wires between the absorption layers are bent, so that the load is transmitted to the periphery, the pressure is dispersed in a larger radius range, the compression load born by the diaper is reduced, and after the pressure disappears, the deformation of the diaper/the diaper is rapidly recovered due to the existence of the spacer fabric. Secondly, the diaper/diaper of the invention has good air permeability and can prevent diaper rash, and the air permeability of the spacer fabric with the upper layer and the lower layer which are light and thin and loose mesh structures 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. In addition, the diaper/diaper has good moisture absorption and moisture conduction functions, can effectively prevent side leakage, and the upper surface layer of the loose structure can enable urine to quickly permeate into the upper surface layer and be transmitted to the other surface of the fabric through the capillary effect of the spacing threads of the absorption layer and be fully absorbed by the high-water-absorption fibers in the processAnd the side leakage caused by the untimely absorption of urine can be avoided. The traditional diaper/diaper needs multilayer compounding, adhesive and the like are used, the production process can cause serious environmental pollution, the spacer fabric does not need compounding and chemical bonding, the bottom sole layer in the diaper can be bonded by hot melt fibers on the lower surface layer of the spacer fabric, and chemical bonding agents are not needed, the diaper can be integrally formed, and therefore the environmental pollution is greatly reduced. 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.
