Technical field
The invention belongs to technical field of artificial leather, and in particular to the super soft leather base cloth fiber of one kind and its manufacturing method.
Background technique
In recent years, the raw material skin resource of natural leather is more and more expensive, and quantity is fewer and fewer, far from can satisfy market
Demand, therefore, countries in the world all replace natural leather material accelerating to develop new material, however the material of most of exploitations
Material and investment leather are also to have very big gap, in terms of can not reach the demand in market, while its phase
To harder, flexility is relatively low.
Chinese patent application CN102425068A is disclosed uses aqueous polyurethane dipping compound the invention discloses a kind of
The method that method produces superfine fiber synthetic leather base cloth, using not weaving fabric of superfine fiber as substrate, using superfine fiber chemical leather plus
Dipping equipment complex during work, first not weaving fabric of superfine fiber are by being equipped with aqueous polyurethane, chemical foaming agent and height
The dipping tank of carbon alcohol mixed slurry, allows mixed slurry to be impregnated with not weaving fabric of superfine fiber completely；Then by padding machine, by roll it
Between gap width control not weaving fabric of superfine fiber in slurry amount, extra slurry is squeezed out, baking oven is then passed through
It is dried, controls drying temperature and the time carries out chemical blowing, be the water being filled between not weaving fabric of superfine fiber fiber
Property polyurethane forms porous obturator, obtains superfine fiber synthetic leather base cloth；Finally by superfine fiber synthetic leather base cloth heat
Water is washed, and the porous aqueous polyurethane obturator continuously penetrated through is ultimately formed, and is obtained with ventilative and vapor pervious performance
Superfine fiber synthetic leather base cloth, but it is comparatively, and mechanical property is relatively low, and service life is shorter.
Above-mentioned patent there are aiming at the problem that, the present invention, which has developed super soft leather base cloth fiber, can be good at meeting market pair
The demand of leather.
Summary of the invention
In order to achieve the purpose that in background technique, the super soft leather base cloth fiber of one kind proposed by the present invention and its manufacturing method；
What the present invention realized by the following technical solutions:
The super soft leather base cloth fiber of one kind and its manufacturing method, comprising the following steps:

(2) a kind of super soft leather base cloth fiber and its manufacturing method are as follows: modified polyurethane, 10-15 by mass fraction for 50-60 parts
Part flexible fiber, 15-20 parts of lignocellulosic, 6-8 parts of flexibilizing agent, 3-5 parts of lubricant, 10-20 parts of filler,
3-5 parts of age resister, 1-2 parts of Masterbatch are added in batch mixer agent and are mixed, and after mixing, material are added and is dried
It is dried in machine, material is added in parallel single screw extrusion machine after 80-90 DEG C, drying and is plasticized by drying temperature
Type is prepared into compared with thickness after 0.5-1 centimetres of thin slice, by the thin slice send to four-roll calender be rolled into required for thickness and
Then the film of width is bonded with the base fabric heated in advance in calender high temperature, after then embossing, cooling,
It is cut and is wound, then packed, which is exactly super soft leather base cloth.
The substance used in above-mentioned steps the preparation method is as follows:
(1) preparation of modified polyurethane
By 100-120 parts of polyurethane, 12-15 parts of poly- acetate fiber, 4-8 parts of polyvinyl alcohol, the coupling of 1-2 parts of silicon ether
Agent, 2-3 parts of lubricant are added in batch mixer and are mixed, and after mixing, material are added twin-screw extrude progress
Modified and granulation squeezes out, and obtains modified materials grain, which is exactly modified polyurethane.
(2) preparation of flexible fiber
By 10-20 parts of polymethyl methacrylate, 6-8 parts of polybutyl methacrylate, 2-5 parts of polyvinyl alcohol, 5-10
The poly- acetate fiber of part, 4-5 parts of low density polyethylene (LDPE) are added in batch mixer and are mixed, the substance obtained after mixing,
The substance is exactly flexible fiber.
(3) preparation of flexibilizing agent
Temperature of reaction kettle is controlled at 60-70 DEG C, by DOP, 8-12 part of EVA, 20-30 part of 5-10 parts ABS, 4-5 part
TPP is added in reaction kettle, and after carrying out hybrid reaction 2-3 hours, obtained substance, the substance is exactly flexibilizing agent.
(4) preparation of lubricant
By temperature of reaction kettle control at 60-70 DEG C, revolving speed controls PE wax, 3- in 200-300rpm, by mass fraction for 5-6 parts
The substance obtain after hybrid reaction is added in reaction kettle in 6 parts of fatty acid ammonium, 1-2 parts of lauric acid, which is exactly to moisten
