Description
Technical field
The present invention relates to a kind of nursing materials, more particularly, to a kind of bio-degradable expendable nursing materials and its preparation side
Method.
Background technology
There are statistics to show, a women will undergo 60 day menstrual period for 1 year, take around within 1 year 480 sanitary napkins,
Calculated according to a piece of 10 grams of sanitary napkin weight, thus 2,000,000,000 women, the 1 year rubbish that will produce 9,600,000 tons or so；Separately
Outside, with the continuous development of economy and constantly bringing forth new ideas for product quality, the dosage of Chinese children paper diaper is growing day by day；Moreover,
With the arrival of aging of population, the incontinent patients number such as the patient of long-term bed, patient with severe symptoms is also continuously increased, incontinence article
Also receive much concern.Since the volume that these " white garbages " occupy is bigger, landfill disposal is carried out according to existing processing method
Need to consume substantial amounts of landfill yard, occur seizing arable land good farmland with the mankind, corrode the serious problems of human habitat, because
And degradable disponsable nursing materials is produced and uses, change material therefor in existing product, be allowed to discarding and be buried in underground
Afterwards, degraded can be produced by the regular hour, returns the living environment of mankind's green, it is very necessary.
Chinese patent CN 2868262 discloses a kind of sanitary belt for being capable of whole degradation treatments, by degraded wood pulp paper, drop
Spunlace non-woven cloth composition is solved, degraded wood pulp paper is on degraded waterproof wood pulp paper, and degraded spunlace non-woven cloth is positioned at degraded wood pulp paper
It is upper and compound with degraded waterproof wood pulp paper.Advantage：First, degrade in sanitary belt wood pulp paper and the conjunction of substratum for waterproofing and contact surface layer
Reason design, can not only effectively absorb a small amount of liquid, and substratum for waterproofing and contact layer can be produced after sanitary belt use
Raw slow osmosis, forces waterproof layer and contact layer gradually to break up, degrade, is effectively protected environment；Second, greatly
Production cost is reduced, the life of people is met and needs at heart.But it is only applicable to absorb a small amount of liquid, function list
One, it is impossible to meet the actual demand of people.
Chinese patent CN 101491687 discloses a kind of corn polylactic acid fiber sanitary napkin, and top layer uses corn polylactic acid
Fiber spun-laced non-woven fabrics, filled layer（Internal layer）Using corn polylactic acid short-fiber, water barrier uses adopting polylactic acid fibers interval
Fabric.The advantages of sanitary napkin set of the present invention polylactic acid fibre and hydro-entangled non-woven fabric, it is soft, uniformly have it is good
Gas permeability well, water imbibition, skin-friendly, product have excellent antibiotic property, antibacterial and mildew resistance, and fully biodegradable
Property.But it still remains complex production process, the sanitary napkin water absorbent rate that is difficult to realize national Specification have to be larger than 7
Times standard and single function the characteristics of, thus the market faced and use groups are narrow, are subject in popularization and application certain
Limitation.
