Description
Technical field
The present invention relates to non-woven fabric composite material fields, and in particular to a kind of polyvinyl alcohol non-woven fabrics coating composite materials
Preparation method.
Background technology
Polyvinyl alcohol (PVA) is used as a kind of environmentally friendly material, be developed rapidly in recent years in many fields and
Using.China is used as vinylon production capacity big country, there is abundant raw material sources and application market, in production vinylon leading portion work
Sequence, polyvinyl alcohol (PVA) do not continue on through acetal processing and are directly used in life through wet spinning coagulating bath vinal after molding
Polyvinyl alcohol non-woven fabrics is produced, and the field for being rapidly developed and applying in recent years.Due to the water-soluble attribute of polyvinyl alcohol
With environmental-friendly characteristic, start to replace the non-woven fabrics manufactured as raw material using plastic synthetic resin in many fields.Such as shoemaking, system
Leather, mattress, child-mother-covering, decoration, chemical industry, printing, automobile, building materials, the industries such as furniture and dress lining cloth, health care are disposable
The gift bag of operating coat, mask, cap, sheet, the disposable tablecloth in hotel, beauty, Saunas or even current fashion, fine work bag, shopping
Bag, advertising bag etc..Especially disposable application field can replace traditional plastic synthetic resin nonwoven completely
Cloth, and product is made to have more the feature of environmental protection.
By technology of preparing and the technique of vinal it is found that poly-vinyl alcohol solution is through wet spinning, the nascent fibre of gained
Dimension solidifies in alkaline coagulating bath, at fibre after neutralized, washing and multistage super drawing and heat treatment, obtains with excellent mechanical
The vinal of performance, not only intensity is high, and modulus is high, and the dispersibility of fiber is also very good.It can be produced with this fiber
Go out the polyvinyl alcohol non-woven fabrics of various specifications.
Since polyvinyl alcohol fusing point is up to 220-230 DEG C, and under heating condition, polyvinyl alcohol is begun to out at 180 DEG C
Existing unstable and decomposition aggravates with the not only decomposition that continues to rise of temperature, and along with crosslinking generation；So pure is poly-
Vinyl alcohol is that do not have thermoplastic, that is, does not also have thermoplasticity with the non-woven fabrics prepared by vinal, this is
One of maximum defect of polyvinyl alcohol non-woven fabrics, i.e., cannot be as the non-woven fabrics prepared by other common plastic synthetic resins
With excellent heat sealability, it is made to be subject to certain restrictions in application field, such as second of processing of non-woven fabrics：Edge sealing, envelope
Mouth, bag making etc. can only carry out traditional suture rather than be realized by the technique of automatic heat-seal processing equipment.It results in this way
Processing efficiency is low, cost increases severely.
