Sanitary napkin polymer absorption core and special hole opening device thereof

Abstract

The invention discloses a sanitary napkin polymer absorption core. The sanitary napkin polymer absorption core comprises a core body, wherein the core body comprises fluff pulp and a coating layer wrapped outside the fluff pulp, the fluff pulp is mixed with polymer absorption resin, the core body is provided with core body holes through a hole opening device so that sufficient absorption capacityof the core body can be maintained and the air permeability can be greatly enhanced, and meanwhile the liquid absorption can be accelerated, the side leakage risk of the sanitary napkin can be reduced, so that the sanitary napkin is beneficial to the physical and mental health of consumers, the quality of life is improved, and the hole opening device can open holes for a large number of absorptioncores to achieve continuous production.

Description

technical field [0001] The invention relates to a hygienic product, in particular to a polymer absorbent core body of a sanitary napkin and special opening equipment thereof. Background technique [0002] At present, in the market of sanitary products, sanitary napkins have basic absorption capacity, but there are still limitations in product air permeability. Ordinary sanitary napkins are mainly composed of surface layer, absorbent core and waterproof bottom film. Among them, the surface layer will use pores. The hot air / spunbonded non-woven fabric with high efficiency and good penetrability, the bottom film is mostly made of breathable and waterproof PE bottom film to solve the problem of moisture permeability of sanitary napkins, but the problem of breathability of the absorbent core has not been effectively solved. Improvement, the absorbent core will swell after absorbing menstrual blood and form a gel form to form a barrier layer, which will greatly reduce the breathab...

Problems solved by technology

[0002] At present, in the market of sanitary products, sanitary napkins have basic absorption capacity, but there are still limitations in product air permeability. Ordinary sanitary napkins are mainly composed of surface layer, absorbent core and waterproof bottom film. Among them, the surface layer will use pores. The hot air / spunbonded non-woven fabric with high efficiency and good penetrability, the bottom film is mostly made of breathable and waterproof PE bottom film to solve the problem of moisture permeability of sanitary napkins, but the problem of breathability of the absorbent core has not been effectively solved. Improvement, the absorbent core will swell after absorbing menstrual blood and form a gel form to form a barrier layer, which will greatly reduce the breathability and moisture permeability of sanitary napkins, and consumers often feel stuffy after use. Absorbent cores under wet conditions can easily lead to the growth of microorganisms, which will have a negative impact on consumers' physical and mental health
