Description
Technical field
The present invention relates to a kind of synthesis footwear leather more particularly to a kind of high density kraft fibers synthesis footwear leather and its preparation sides
Method.
Background technology
Chinese shoemaking is a dark horse, and in two short ten years, becomes global maximum footwear producing country and outlet
After state, particularly China's entry into the WTO, powerful developing state is more presented in Chinese shoemaking, at present only China's shoes market capacity
Just there are hundred billion total values.
In China, footwear material stepped on leather, Bai Lu leathers etc. with grass cloth, cattle and sheep hair, original sootiness leather, oil before this
Based on various leathers and natural fabric material, with the straw sandals that are made by handwork, cloth shoes, high felt boots and skin base fabric face footwear etc..With section
The development of technology, shoemaking industry are widely used natural and high molecular synthetic material；Due to the difference using raw material, at me
State is divided into 4 kinds of cloth shoes, rubber overshoes, leather shoes and plastic shoes footwear at present.
1. natural leather
Natural leather occupies an important position in shoemaking, except with absorbing sweat, breathing freely, softness, comfortable excellent performance, also
With following features：(1) it is strong but pliable in texture；Pedal skin can be protected from the injury of external world's contact；(2) it is easy to dye；(3) it is cold-proof
It works well；Although leather has porous performance, since these ducts are led directly to as textile, so strong wind is just
Cannot be directly through leather and skin contact, thus leather has cold-proof；(4) good forming effect；To the adaptable of last carving body,
Stable structure after sizing, is unlikely to deform；(5) shortcoming is variant between position, and the difference of ectonexine is big, there is disability,
It intolerant to microbial action, easily mildews, is extended after moisture absorption, dry after-contraction.
2. alternative leather
Shoemaking is mainly artificial leather, two major class of synthetic leather with alternative leather.(1) artificial leather；Artificial leather material is mainly with high
The mixture that Molecularly Imprinted Polymer, plasticizer, stabilizer and other auxiliary agents form is coated in what is processed from strand again on various bases,
It is main leather substitute material；The base of artificial leather has textile cloth, non-woven cloth, looped fabric etc., is nitrified including low nitrogen fine
The plain artificial leather of dimension, artificial polyvinyl chloride leather and foamed polyvinyl chloride artificial leather；(2) synthetic leather；Synthetic leather is the base in artificial leather
Grow up on plinth, using non-woven cloth as base, after new type resin dip-coating, the leather goods of grade separation structure be presented,
The hygroscopicity of this material, good permeability, fastness are also greatly improved than artificial leather.Coating is (poly- with novel synthetic material-PU
Urethane) based on, then by various ornamentings, including pressing upper natural leather pattern and using corrugation technology, staining technique, substantially improving
Appearance, not only that with natural leather plentiful, soft feel, but also bright in colour, abrasion resistance, resistance to bend(ing),
Tear resistance etc. is all better than artificial leather, so being widely used in shoe-making field.
3. rubber material；This high-molecular compound not only has high resiliency, also with high-wearing feature and flexible resistance, makes
Shoe rubber product is light and flexible, and frictional dissipation is small, can be subjected to repeatedly being bent, stretch, compresses without being destroyed；Meanwhile
Rubber also has impermeability, air impermeability, resistance to acid and alkali, insulating properties excellent and the characteristic properties such as adhesive strength is high, thus, into
For good material for shoes, the characteristics of being satisfied with each leather shoes kind and requirement, the bottom parts or other components instead of leather are (main
With and footwear decoration etc.), have a wide range of applications in shoemaking industry.
4. plastic material；Plastics are to add in (or being not added with) filler, plasticizer into other additives by synthetic resin, by adding
The rigid material that the plastic material or curing curing that work forms are cross-linked to form.Plastics are light, mechanical change model circle is wide, corrosion resistance
Energy is excellent, good insulating, moulding processability is good, wearability is good, translucency and its barrier propterty are good, but poor heat resistance, makes
With cold flow, fatigue and crystallization easily occur in the process, resistance to ag(e)ing is poor, and thermal conductivity is bad.Occupy in China's shoemaking industry very big
Ratio.Can not be always effectively the pain spot of industry using corium onal material, at present, corium is broken meanwhile in leather industry
Cladding can only be as industrial gelatine or few edible gelatin and the leather shoes of poor quality etc..
