Abstract
The invention relates to a polylactic acid fiber non-woven fabric used for a hygienic material, belongs to the technical field of hygienic materials, and solves the problem that the present non-woven fabrics are single in function. The polylactic acid fiber non-woven fabric used for the hygienic material is by a pure polylactic acid fiber or a mixture of a polylactic acid fiber and a non-petroleum based fiber, the mixture comprises 50 to 100 % of polylactic acid fiber and 0 to 50 % non-petroleum based fiber. The polylactic acid fiber is used as the raw material of the polylactic acid fiber non-woven fabric, the polylactic acid fiber non-woven fabric is pure natural, bacteriostatic without sensitization, the plant source fiber is smooth, bacteriostatic, and can ventilate, drain sweat, relief itch and care skin. The non-petroleum based fiber is used for blending, natural characteristics of the polylactic acid fiber cannot be influenced, and defects of hydrophobicity and hard handfeel of the polylactic acid fiber can be overcome. Negative ions and traditional Chinese medicines are added in the non-woven fabric, special medical performances of the product can be increased, a medical need of the non-woven fabric used for the hygienic material can be met.
Description
Technical field
The invention belongs to hygienic material technical field, relate to a kind of nonwoven fabric of hygienic material, particularly a kind of degradable and possess the acid fiber by polylactic nonwoven fabric of natural bacteriostatic ability.
Background technology
Along with the reinforcement of social environment consciousness, the development and application of biodegradable polymers has caused people to pay close attention to greatly.PLA (PLA) is the representative that the biodegradable fat of chemical synthesis belongs to polyester, and it has good biocompatibility and security, harmless to human non-toxic, degrades gradually in vivo and in natural environment, finally becomes carbon dioxide and water.The monomer of PLA is lactic acid, and it is formed through probiotics fermention by renewable resource starch (extracting from corn, cassava and straw), and raw material sources are very abundant.
The nonwoven fabric mainly raw material based on vistanex that the Disposable Sanitary Accessory such as current paper diaper, sanitary napkin are used, its degradation time in natural environment reaches centuries, therefore creates serious " white pollution ".Again; along with the raising of human living standard; the protective awareness of consumer to health strengthens day by day; and the hygienic material sold in the market and the amenities made thereof do not possess antibacterial functions substantially; therefore there is many hidden danger such as secondary pollution, cross infection, to the healthy formation potential threat of user.
Summary of the invention
The object of the invention is the problems referred to above existed for prior art, propose one and possess natural bacteriostatic, pro-skin and degradable acid fiber by polylactic nonwoven fabric.
Object of the present invention realizes by following technical proposal: a kind of acid fiber by polylactic nonwoven fabric for hygienic material, it is characterized in that, it adopts, and pure acid fiber by polylactic or acid fiber by polylactic and non-petroleum base fiber are mixed to be formed, described acid fiber by polylactic accounting is 50% ~ 100%, and described non-petroleum base fibre weight accounting is 0% ~ 50%.
Acid fiber by polylactic plays natural bacteriostatic effect, and without advantages such as sensitization, pro-skin skin cares, add that different functional materials can increase that its anion occurs, far infrared transmission or analgesia, the function such as the Chinese herbal medicine that eliminates the unusual smell, improve the functional of this hygienic material nonwoven fabric further.
Above-mentioned in the acid fiber by polylactic nonwoven fabric of hygienic material, described non-petroleum base fiber is wherein one or more such as cotton fiber, wood pulp fibre, bamboo fibre, chitin fiber.
Above-mentioned in the acid fiber by polylactic nonwoven fabric of hygienic material, described acid fiber by polylactic and non-petroleum base fiber adopt hot blast, hot rolling, water sting, the processes such as spunbond forms.
Can anion be provided with in the acid fiber by polylactic nonwoven fabric of hygienic material between described acid fiber by polylactic and non-petroleum base fiber above-mentioned, when nonwoven fabric is used, possess anion-generating capacity.
Above-mentioned in the acid fiber by polylactic nonwoven fabric of hygienic material, between described acid fiber by polylactic and functional fiber, Chinese medicine preparation can be provided with.According to the Chinese medicine of different increase in demand as analgesia, sterilization, the effect such as to eliminate the unusual smell, the pharmaceutical characteristic of nonwoven fabric can be promoted, is more applicable for the hygienic material such as sanitary napkin, paper diaper.
Above-mentioned in the acid fiber by polylactic nonwoven fabric of hygienic material, described nonwoven fabric grammes per square metre is 15 ~ 60mm.
Compared with prior art, this acid fiber by polylactic nonwoven fabric tool has the following advantages: 1), adopt acid fiber by polylactic as raw material, have that pure natural is antibacterial, without the advantage of sensitization, its plant source fiber has the health-care effect such as smooth, ventilative, perspire, antipruritic, antibacterial bacteriostatic, pro-skin skin care; 2), adopt non-petroleum base fiber blend, do not affect the natural ecological of acid fiber by polylactic, 2 deficiencies that pure acid fiber by polylactic refuses water and Boardy Feeling can be improved; 3) in nonwoven fabric, add anion and traditional Chinese medicine ingredients, the specific pharmaceutical characteristic of product can be increased, meet nonwoven fabric for medicinal demand during hygienic material.
Detailed description of the invention
Be below specific embodiments of the invention, technical scheme of the present invention is further described, but the present invention is not limited to these embodiments.
Embodiment 1
This is used for the acid fiber by polylactic nonwoven fabric of hygienic material, and adopt pure acid fiber by polylactic to make, its technological process is as follows: → section feeding → melt extruded → spinning → cooling drawing-off → sub-wire lapping → fibre web hot rolling reinforcing → trimming winding is dried in section.In fibre web reinforcing process, anion or traditional Chinese medicine ingredients can be added between the fibre web of different layers, make shaping nonwoven fabric possess negative ion generating function or specific medicinal effects.
The grammes per square metre of this acid fiber by polylactic nonwoven fabric finished product is 15 ~ 60mm.
This acid fiber by polylactic nonwoven fabric tool has the following advantages: 1), adopt acid fiber by polylactic as raw material, have that pure natural is antibacterial, without the advantage of sensitization, its plant source fiber has the health-care effect such as smooth, ventilative, perspire, antipruritic, antibacterial bacteriostatic, pro-skin skin care; In nonwoven production process, add the composition such as negative ion powder, Chinese medicine, the specific pharmaceutical characteristic of product can be increased, increase negative ion generating function, meet nonwoven fabric for medicinal demand during hygienic material.
