Description
Technical field
The present invention relates to a kind of artificial leather preparation method, particularly a kind of nano-micro fiber preparation method.
Background technology
In recent years because many laws and rules about environmental protection are launched respectively, and the expensive and limited source of corium, people are seeking the substitute of corium, and the synthetic leather adopting superfine fibre to obtain more and more is subject to the welcome in market, current microfiber synthetic leather non-weaving cloth is the basic material making microfiber synthetic leather base cloth, for main raw material with polyamide and polyethylene, pass through melt spinning, traction stretches, curling, the operations such as cut-out make sea-island staple fiber, obtain through combing and needling process again, this kind of production method complex process is loaded down with trivial details, not easily process, and the nano-micro fiber feel of the method gained is harder, differ greatly with fell.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of nano-micro fiber preparation method, this nano-micro fiber preparation method production technology product that is simple, that produce has the advantages such as ventilative, soft, good hand feeling, good springiness.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of nano-micro fiber preparation method, and concrete steps are as follows:
Step one: mix:
A, 5-10kg dimethyl formamide, 2-10kg hydrolysis mill base and 1-3kg surfactant high-speed stirring is even, filter stand-by;
B, by 80-100kg high hydrolysis resistance polyurethane resin and 150-280kg dimethyl formamide mixing and stirring, leave standstill mix with slurry in step a after 20-45 minute after stir under 20 DEG C of-40 DEG C of temperature conditions, and deaeration filtration static, froth breaking is stand-by;
Step 2: select the uniform fleece of fluffing;
Step 3: wet method bass is produced:
By in the fleece the chosen slurry that fully impregnation prepares in stepb after whole scalding, make in flannelette containing high hydrolysis resistance polyurethane resin, then put in the middle of dimethylformamide in water that mass percent concentration is 12-25% and solidify, then carry out multiple tracks washing, namely extruding post-drying obtains nano-micro fiber wet method bass;
Step 4: post processing mill skin:
Above-mentioned nano-micro fiber wet method bass carries out surface finish through sand paper when running up, until its Surface feel exquisiteness, the feel of wool are evenly; After polishing, the nano-micro fiber product of gained to be got product nano-micro fiber by net grain surface process again.
As a further improvement on the present invention, the mixture high-speed stirred 60-90 minute in described step a.
As a further improvement on the present invention, the high hydrolysis resistance polyurethane resin in described step b and dimethyl formamide mix high-speed stirred 30 minutes.
As a further improvement on the present invention, in described step b high hydrolysis resistance polyurethane resin and dimethyl formamide mixing and stirring after leaving standstill with slurry in step a mix and blend and deaeration in the reactor of negative pressure vacuum-pumping, mixing time is 2 hours.
As a further improvement on the present invention, in described step 3 wet method bass production stage, baking temperature is 100-160 DEG C, and this operation speed of a motor vehicle controls at 6-15m/min.
As a further improvement on the present invention, in described step 4, the nano-micro fiber wet method bass of post processing mill skin operation adopts 100 order sand paper to polish.
As a further improvement on the present invention, the nano-micro fiber product in described step 4 after polishing is by 100 order net grain surface process.
The invention has the beneficial effects as follows: the present invention mainly adopts high hydrolysis resistance polyurethane resin to prepare wet method bass, skin is ground through post processing in its surface, its nano-micro fiber of producing has that surface is fine and smooth, the feel of wool evenly, there is the advantage such as certain puckery feel, ventilative, softness, good hand feeling, good springiness.
