Description

A kind of super water absorbent quick-drying paper diaper
Technical field
The invention belongs to new function material technical fields, and in particular to a kind of super water absorbent quick-drying paper diaper.
Background technique
The user group of paper diaper mainly has baby and adult's two major classes.Wherein Chinese market is mainly baby's paper urine Trousers, China have nearly 20,000,000 baby due every year, reach more than 4,000 ten thousand using 0 years old to 2 years old baby of urine pants.And according to state The data of statistics bureau, family, 60 years old or more the population in the whole nation in 2008 reach 1.599 hundred million people, account for the 12% of total population；Over-65s it is old Year population reaches 1.096 hundred million people account for total population 8.3%.
Diaper rash is the stimulation of mixture and cloth diaper (or paper diaper of poor quality) to skin because of urine and stool With inflammation caused by friction, all occurs micro- red phenomenon from private parts to buttocks, skin can become coarse, or even occur superfine small Acne.If the small long prickly heat of hip, while could also cause diaper using air-locked cloth diaper or the paper diaper of poor quality again Rash.
As the promotion of living standard and science and technology strength develops, it is impossible to meet people for traditional diaper and paper diaper Demand, the market competition of paper diaper is also more fierce.And to the promotion of paper diaper product nothing more than from use feeling and Health environment-friendly angle is set out.Since paper diaper are directly contacted with human skin, the environment in urine is suitble to bacterial growth breeding, grows Raw bacterium can be adsorbed on paper diaper surface, and then be adhered to skin, and the continuous breeding of bacterium is caused to accumulate.Existing paper diaper The adsorbent material used either plant processing extract component or polymer adsorbing material, adsorption capacity is extremely limited, is easy It bursts, and does not all have anti-reflective osmosis, absorption speed is slow, causes urine to contact for a long time with skin, antibacterial effect obtains not To effective guarantee.It is easy to cause uncomfortable and infection, therefore it provides a kind of super water absorbent quick-drying paper diaper have highly important meaning Justice.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of super water absorbent quick-drying paper diaper, the paper diaper of formation are provided Core material structure is fine and close hydration at water absorbing capacity with super strength keeps skin surface dry and comfortable, additionally it is possible to inhibit bacterium Adherency.
