Description

A kind of bio-degradable expendable nursing materials
Technical field
This utility model relates to a kind of nursing materials, especially relates to a kind of bio-degradable expendable nursing materials.
Background technology
Have statistics to show, a women will experience 60 days menstrual phases for 1 year, and within 1 year, approximately need 480 sanitary towels, calculate according to a slice sanitary towel weight 10 grams, thus 2,000,000,000 women will produce the rubbish of about 9,600,000 tons for 1 year; In addition, along with the development of economy and constantly bringing forth new ideas of product quality, the consumption of Chinese children diaper grows with each passing day; And along with the arrival of aged tendency of population, the incontinent patients number such as patient, patient with severe symptoms of long-term bed also constantly increases, and incontinence article also receives much concern.The volume ratio of occupying due to these " white garbages " is larger, carry out landfill disposal according to existing processing method to need to consume a large amount of landfill yards, the serious problems seized good farmland, arable land with the mankind, corrode human habitat are there are, thus, produce and use degradable disponsable nursing materials, changing material therefor in existing product, after making it to abandon and being buried in underground, can degraded be produced through the regular hour, return the living environment of mankind's green, very necessary.
Chinese patent CN 2868262 disclose a kind of can the sanitary belt of whole degradation treatment, be made up of degraded wood pulp paper, degradation water prick nonwoven cloth, degraded wood pulp paper is positioned on degraded waterproof wood pulp paper, degradation water prick nonwoven cloth to be positioned on degraded wood pulp paper and with degraded waterproof wood pulp paper compound.Advantage: one is the appropriate design of wood pulp paper and substratum for waterproofing and contact surface layer of degrading in sanitary belt, can not only effectively absorb a small amount of liquid, and can after sanitary belt uses, osmosis is slowly produced to substratum for waterproofing and contact layer, force watertight composition and contact layer to break up gradually, degrade, effectively protect environment; Two is greatly reduce production cost, meets the life of people and needs at heart.But it is only applicable to absorb a small amount of liquid, function singleness, can not meet the actual demand of people.
Chinese patent CN 101491687 discloses a kind of corn polylactic acid fiber sanitary napkin, and top layer adopts adopting polylactic acid fibers spun-laced nonwoven fabric, and packed layer (internal layer) adopts Semen Maydis polylactic acid short-fiber, and water barrier adopts adopting polylactic acid fibers space fabric.This utility model sanitary towel has gathered the advantage of polylactic acid fibre and hydro-entangled non-woven fabric, soft, evenly have good breathability, water absorption, skin-friendly, and product has excellent antibiotic property, antibacterial and mildew resistance, and fully biodegradable.But it still exists complex manufacturing, be difficult to realize sanitary towel's water absorbent rate of national Specification must be greater than the standard of 7 times and the feature of function singleness, the market thus and use colony narrow, popularization and application is subject to certain restrictions.
Utility model content
In order to overcome the deficiency that prior art exists, this utility model provide a kind ofly not rupture, safety is good, water absorption is strong, water-retaining property is good bio-degradable expendable nursing materials.
A kind of bio-degradable expendable nursing materials, comprise the surface layer, sandwich layer and the bottom that from top to bottom arrange in turn, described surface layer adopts the non-woven fabrics be made up of acid fiber by polylactic or the non-woven fabrics being mixed with wood pulp cellulose by acid fiber by polylactic and make, described sandwich layer comprises the first absorbed layer and the second absorbed layer that from top to bottom arrange in turn, first absorbed layer and the second absorbed layer all adopt and are mixed with wood pulp cellulose by acid fiber by polylactic and the non-woven fabrics made, and are evenly impregnated with water absorbing polymer particle respectively in described first absorbed layer and the second absorbed layer; Described bottom adopts the non-woven fabrics be made up of acid fiber by polylactic.
This utility model surface layer can quick absorbing fluid dredge and enter sandwich layer, and leakproof is only oozed, polylactic acid provide simultaneously good antibacterial, eliminate the unusual smell and the function such as biodegradable; Sandwich layer contains superabsorbent water water absorbing polymer particle, and absorbing fluid fully and completely; Containing the ventilative bottom of acid fiber by polylactic antibacterial and eliminate the unusual smell simultaneously, steam can be derived rapidly, human body is kept fit state at any time.This utility model can play integral adhesive after the heating, need not carry out bonding additionally by adhesive again, can not affect water absorbing properties, and in addition, wood pulp cellulose can also play the effect increasing absorption speed.
As preferably, described surface thickness is 0.1 ~ 1.0mm.While guarantee absorbtivity, improve the comfort level of user.
As preferably, described underlayer thickness is 0.1 ~ 1.0mm.While guarantee absorbtivity, improve the comfort level of user.
This utility model surface layer can adopt and be mixed with wood pulp cellulose by acid fiber by polylactic and the non-woven fabrics made, and wherein, the percentage by weight of acid fiber by polylactic is 20 ~ 50%, and the percentage by weight of wood pulp cellulose is 50 ~ 80%.The rapid absorbing fluid of energy is also dredged fast and is entered sandwich layer, and leakproof is only oozed, and acid fiber by polylactic provides the good antibacterial and function that eliminates the unusual smell simultaneously, extends working time.
In described first absorbed layer, the percentage by weight of acid fiber by polylactic is 20 ~ 40%, and the percentage by weight of wood pulp cellulose is 60 ~ 80%; In second absorbed layer, the percentage by weight of acid fiber by polylactic is 20 ~ 40%, and the percentage by weight of wood pulp cellulose is 60 ~ 80%.
Acid fiber by polylactic is adopted to mix with wood pulp cellulose, important impact is there is in the weight proportion of acid fiber by polylactic and wood pulp cellulose for the performance of product, along with the increase of acid fiber by polylactic proportioning, its breathability and drainability increase, but the mechanical property such as tear index and folding strength reduces, therefore, comprehensive consideration need be carried out, to obtain applicable appropriate proportioning of the present utility model.
The hydrophobic performance of this utility model acid fiber by polylactic provides surface dry may just as well for disposable nursing materials, the smooth surface of acid fiber by polylactic provides not easily sensitization for disposable nursing materials, and polylactic acid is with weak lactic acid characteristic, there is the well antibacterial and function that eliminates the unusual smell, steam can be derived rapidly, human body is kept fit state at any time.Composite construction of the present utility model not only has pro-skin, softness, the performance such as comfortable, and easily can realize biodegradation, can not cause burden to environment, can bring the mankind and live more easily and beautiful green environment.
