The utility model discloses a composite water-absorbing inner core for a sanitary towel, which comprises: the sanitary towel comprises a pasting core body, dispersing core strips, high-molecular water-absorbent resin and a vertical flow guide core body, wherein dust-free paper is arranged on the upper side and the lower side of the high-molecular water-absorbent resin, the pasting core body is arranged in the center of the bottom of the dust-free paper positioned at the bottom, the dispersing core strips are arranged on the two sides of the pasting core body, and a flow guide fiber layer is arranged on the top of the dust-free paper positioned at the top.
Description
Technical Field
The utility model relates to the technical field of sanitary articles, in particular to a composite water-absorbing inner core for a sanitary towel.
Background
The sanitary napkin is a sanitary article for women in menstrual period, and is mainly made of high-molecular polymer and high-molecular polymer composite paper formed from cotton, non-woven fabric, paper pulp or composite material of above materials, and its side edge is mainly designed for preventing side leakage, and is divided into three layers of surface layer, absorption core and bottom layer from inside to outside. The sanitary towel mainly comprises a surface layer, an absorption core and a bottom layer, wherein materials of all layers are bonded by hot melt adhesive. The absorption core is generally made of fluff pulp mixed with high molecular water absorbent and wrapped by toilet paper, and forms a strong absorption body, and once menstrual blood permeates into the absorption core, the menstrual blood is firmly attached and cannot reversely or scattered.
The reverse osmosis phenomenon can appear in inside compound inner core that absorbs water under the effect of pressure of current sanitary towel, leads to dirty blood backward flow, breeds a large amount of bacteriums rapidly under the effect of temperature, influences sanitary safety.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a composite water-absorbing inner core for a sanitary towel, which aims to solve the problems that the composite water-absorbing inner core in the sanitary towel proposed in the background art has reverse osmosis phenomenon under the action of pressure, so that the backflow of dirty blood is caused, a large amount of bacteria are rapidly bred under the action of temperature, and the sanitary safety is influenced.
In order to achieve the purpose, the utility model provides the following technical scheme: the compound inner core that absorbs water for sanitary towel includes: paste core, dispersion core strip, polymer water-absorbing resin and vertical water conservancy diversion core, both sides are equipped with dustless paper about the polymer water-absorbing resin, and the dustless paper bottom central authorities that are located the bottom are equipped with pastes the core, it is equipped with dispersion core strip to paste the core both sides, and the dustless paper top that is located the top is equipped with the water conservancy diversion fibre layer, polymer water-absorbing resin central authorities are equipped with vertical water conservancy diversion core, vertical water conservancy diversion core middle part both sides are equipped with horizontal water conservancy diversion strip.
Furthermore, the cross sections of the upper side and the lower side of the vertical flow guide core body are funnel-shaped.
Furthermore, the number of the dispersing core strips is a plurality, and the dispersing core strips are linearly and uniformly distributed.
Furthermore, the transverse flow guide strips are arranged linearly and uniformly.
Furthermore, the bottom of the pasting core body is pasted with the bottom film of the sanitary towel.
Furthermore, the dispersing core strip is made of absorbent cotton.
Compared with the prior art, the utility model has the beneficial effects that:
according to the utility model, through the arranged pasting core body, the dispersing core strips and the transverse diversion strips, when the composite water-absorbing inner core for the sanitary towel is used, liquid is quickly guided and dispersed through the diversion fiber layer, so that the liquid can be conveniently and uniformly permeated into the high-molecular water-absorbing resin, the liquid is quickly guided to the bottom of the high-molecular water-absorbing resin through the vertical diversion core body, the liquid is guided to two sides of the high-molecular water-absorbing resin through the transverse diversion strips, the liquid is prevented from being stored and reversely permeated, the whole composite core body is pasted with the bottom film of the sanitary towel through the pasting core body, the two sides of the bottom of the composite core body and the bottom film of the sanitary towel are in a free state, so that the liquid can be conveniently absorbed and permeated through the two sides, the liquid can be uniformly and efficiently absorbed by the composite core body, the liquid is prevented from being stored and causing extrusion and reverse osmosis, and the health and safety of the sanitary towel in the use process are ensured.
