Description
Technical field
The present invention relates to shoe-pad preparing technical field, particularly a kind of foam material for the preparation of functional innersole and functional innersole thereof.
Technical background
Shoe-pad, this every day, with our unremarkable pocket-handkerchief, along with the reach of science and growth in the living standard, is valued by the people day by day, and people get more and more to the requirement of the aspects such as the comfortableness of shoe-pad, health, security and the feature of environmental protection.On market, therefore the shoe-pad of various material, all styles of, various function also emerges in an endless stream.
Divide from material, six large classes can be divided into:
1. various fabric class
Cotton, bamboo fibers, brown fiber etc. are all applied on shoe-pad, and the shoe-pad water absorbability that these fibers make, ventilation property are better, but poor flexibility, use when being unfavorable for motion, especially traditional textile shoe-pad, though water absorbability is good, once people when volume of perspiration of moving is larger, cotton fibre is also because of wet swelling, its fortune declines and glues and is posted on skin, and meanwhile, it is slow that moisture distributes speed, thus cause cold wet sensation to human body, make us uncomfortable.
2. natural and imitation leather
Insole function is single, and material is comparatively hard, poor flexibility, and long-time walking foot easily produces discomfort.
3.EVA class
Flexibility is general, but substantially nonelastic, easy distortion, easy smelly pin.
4. latex class
Shoe-pad is soft, but elasticity is general, has a sensation of flooring.
5.PU class
Flexibility is good, good springiness, the also certain absorption of perspiration of foam shoe-pad that PU manufactures, but is easily hydrolyzed, if better PU you be that " tinea pedis " will be hydrolyzed at most half a year, long-term perspire after peculiar smell.
6. silica type
The silica gel shoe-pad of existing market is all silastic insoles, and flexibility is good, and elasticity is pretty good, and deformability is little, but this shoe-pad absorption of perspiration is poor, and dress has the sensation of vexed sweat, and this material density is large, and the shoe-pad of making is relatively heavier, is unfavorable for motion.
From appearance design point, current shoe-pad can be divided into plane, surface has concave-convex design and knockdown.The shoe-pad of the various concave-convex design in surface and built-up type design is generally to suit completely with foot type, give shoe-pad some function, but due to individual difference, on market, shoe-pad finished product can not suit completely with everyone foot type.
Functionally divide, have height-increasing insole, damping insoles, warming insole, antibacterial insoles, orthopedic insoles, especial patient shoe-pad etc.But existing functional insole many employings medicine or other physical construction realize its nourishing function, and complex manufacturing process, cost are high, and health-care effect is limited, and use occasion is restricted, and are difficult to wide popularization and application.
