Abstract
The invention discloses a corn polylactic acid fiber infant paper diaper. The corn polylactic acid fiber infant paper diaper integrates the advantages of a polylactic acid fiber product and the advantages of spunlaced nonwovens, is soft and uniform in hand feeling, has the good breathability and water-absorbing quality, and is skin-friendly; and the corn polylactic acid fiber infant paper diaper has the excellent antibacterial property, the excellent bacteriostat, the excellent mildew resistance and the complete biological degradability. The corn polylactic acid fiber infant paper diaper has the beneficial effects of being large in urine absorption volume, convenient to use, clean, sanitary, free of skin irritations, capable of reducing caused diaper rash, skin injuries or dermatitis and low in cost. The corn polylactic acid fiber infant paper diaper is suitable for infants.
Description
Art
The present invention relates to clothing, object is to design a kind of adopting polylactic acid fibers baby paper diaper, namely top layer adopts adopting polylactic acid fibers spun-laced nonwoven fabric, packed layer (internal layer) adopts Semen Maydis polylactic acid short-fiber, water barrier adopts adopting polylactic acid fibers space fabric, is applicable to the disposable sanitary articles that baby etc. is desirable.
Background technology
Along with quickening and the growth in the living standard of people's life, work rhythm, diaper has almost become the necessary of baby etc.Traditional diaper is common cotton, wet once urinating.The frequent changing babies' napkin of people Chang Huiwei and feel suitable trouble.Now diaper is commercially a feast for the eyes, surfacing and structure basic simlarity, and difference is that some product have employed the design of one-way ventilating hole, the aobvious design of urine at outermost layer, or processes at surfacing.
Corn fiber is a kind of novel environment-protection fiber, the acid fiber by polylactic be made up of Semen Maydis, belong to natural environmental protection type, it has biodegradability and natural antibacterial performance, has fabulous drapability, slipping, sucting wet air permeability simultaneously, good thermostability and anti-ultraviolet function, and have good gloss and elasticity, and the bulkiness of excellence, it has merged the feature of natural fiber and synthetic fibers, integrates both advantages.The premium properties of corn fiber uniqueness, substantially increases the added value of corn fiber, and this is a kind of novel textile material having development prospect.Corn fiber makes raw material with the starch that inexpensive amount is many, has again complete Natural Circulation and the biolytic feature of energy.
Summary of the invention
The present invention mainly applies spun-laced nonwoven fabric production technology, and with Semen Maydis polylactic acid short-fiber for raw material production Jia Gongshi urine pants top layer, packed layer (internal layer) adopts Semen Maydis polylactic acid short-fiber, and water barrier adopts adopting polylactic acid fibers space fabric.The set of the present invention advantage of polylactic acid fibre and hydro-entangled non-woven fabric, soft, evenly have good breathability, water absorption, skin-friendly, product itself has excellent antibiotic property, antibacterial and mildew resistance, and fully biodegradable.Semen Maydis polylactic acid (PLA) fiber is made the diaper with antibacterial effect, effectively can improve value-added content of product.
The technical solution adopted for the present invention to solve the technical problems is: corn fermentation is obtained lactic acid, polylactic acid is obtained through polycondensation reaction, utilize couplant to make to have the higher molecular weight polylactic acid of good mechanical physical property, pass through crucial chemical modification again, application spun-laced nonwoven fabric production technology, be processed into the polylactic acid short-fiber spunlaced antibacterial paper diaper top layer of Semen Maydis, packed layer (internal layer) adopts Semen Maydis polylactic acid short-fiber, and water barrier adopts adopting polylactic acid fibers space fabric.
Mentality of designing of the present invention is that corn fermentation is obtained lactic acid, polylactic acid is obtained through polycondensation reaction, utilize couplant to make to have the higher molecular weight polylactic acid of good mechanical physical property, pass through crucial chemical modification again, its intensity, water-retaining property are promoted, and by its fibrosis, because lactic acid is present in the natural materials between animal, plant and microorganism, be easy to, in the Nature degraded, to endanger to some extent environment.PLA acid fiber by polylactic is made up of starch, can not produce CO2 because of burning, and the combustion heat only has 1/3 of polyester, also can not produce NOX or SOX, and fiber can be broken down into CO2 and H20, totally biodegradable, is the environment-friendly type polyester synthetic fibers of a new generation.
The invention has the beneficial effects as follows, soft, evenly have good breathability, water absorption, skin-friendly, product itself has excellent antibiotic property, antibacterial and mildew resistance, and fully biodegradable.
Detailed description of the invention
Corn fermentation is obtained lactic acid, polylactic acid is obtained through polycondensation reaction, utilize couplant to make to have the higher molecular weight polylactic acid of good mechanical physical property, pass through crucial chemical modification again, its intensity, water-retaining property are promoted, and by its fibrosis, because lactic acid is present in the natural materials between animal, plant and microorganism, be easy to, in the Nature degraded, to endanger to some extent environment.
