Description
Technical field
The invention belongs to new function material technical fields, and in particular to a kind of pro-skin antibacterial 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 anti-bacteria paper
The anti-biotic material that urine pants use either plant component or inorganic antiseptic all do not have anti-reflective osmosis, antibacterial effect
It cannot get effective guarantee.Therefore it provides a kind of have quick absorption, pro-skin antibacterial paper diaper is had a very important significance.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of pro-skin antibacterial paper diaper is provided, the paper urine being prepared
