Description
Technical field
The utility model relates to a kind of Novel Human fabricate-leather, and particularly a kind of real environmental protection of sandwich construction is clean, two-sided polyurethane artificial leather.
Background technology
Along with the conversion of natural conditions and the enhancing of animal protection consciousness, natural leather source and use all more and more are restricted, and artificial leather is as the substitute of natural leather, and its scope of application is increasing.Relevant data shows that the aggregate demand of China's synthetic leather surpasses 800,000,000 square metres/year, and ascendant trend is obvious.
The bottom of ordinary people's fabricate-leather (base material) is generally cloth or synthetic fiber layer, is the double-decker of polyurethane glue-line and base material, and practicality and texture all can not show a candle to natural leather, is lower than natural leather service life equally.
The progressively raising of Along with people's living standard, high-performance, demand high-quality, the environment-protecting clean synthetic leather also increase thereupon.Rough estimates, the demand of high-quality artificial leather are up to 200,000,000 square metres/year, and ascendant trend is apparently higher than ordinary people's fabricate-leather.
Ultra fine leather is the abbreviation of superfine fibre PU synthetic leather; Being the superfine fibre short fiber processes the nonwoven fabric of three-dimensional structure network through combing acupuncture, passes through wet processes again, the impregnation of PU resin; The alkali decrement; Technologies such as polishing dyeing and finishing are finally processed superfine fiber leather, but energy consumption is high, cost is high, price is high, popularizes difficult.Though ordinary people's fabricate-leather outward appearance is beautiful, to arrange well, price is lower, and is not wear-resisting, is prone to break, and energy consumption is high, toxic, and market will be eliminated; Though ultra fine performance has much lifting than the performance of ordinary people's fabricate-leather, even exceeds natural leather,, it still is merely double-layer structure, and range of application is still limited.
Existing ultra fine leather preparation method obtains through prepared such as alkali decrement or toluene (solvent) decrements, and the feel and the back side of product are effective, but its complex process, and also serious to the pollution of environment.Alkali that consumes in the preparation process and organic solvent etc. are difficult to recycle, and environmental pollution has considerable influence, and the general trend of events also necessity is improved.
