Abstract
The invention relates to a method for producing ultra-soft sofa furniture leather. The method is characterized in that raising base cloth containing viscose is selected; the raising base cloth is coated with a polyurethane coating to be produced into a wet half-finished product; and then the wet half-finished product is transferred with release paper patterns, and then the ultra-soft sofa furniture leather is obtained by kneading. The sofa furniture leather can meet the requirements of softness, bulky hand, durability, and the like.
Description
Technical field
The present invention relates to the production method of Synthetic Leather, the production method of a kind of super soft Synthetic Leather of more specifically saying so.
Background technology
Synthetic Leather is called for short the PU synthetic leather, be a kind of with various fabricbases as base material, on base material, apply polyurethane resin and make it give the real leather intimating synthetic leather of various decorative patterns, pattern, function and feel.Traditional PU synthetic leather Boardy Feeling and sense of fullness are poor, if the soft then poor durability of feel, i.e. its pliability technology barriers that can not break through with tool between durability can not satisfy furniture leather softness, good hand feeling, characteristic requirement such as durable.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of production method of ultra-soft sofa furniture leather is provided, so that it satisfies furniture leather softness, good hand feeling, characteristic requirement such as durable.
Technical solution problem of the present invention adopts following technical scheme:
The characteristics of the production method of ultra-soft sofa furniture leather of the present invention are to operate as follows:
A, selection contain the raising base cloth of viscose glue composition
Described viscose glue proportioning by weight is
Viscose glue: 30-100
Terylene: 0-60
Cotton: 0-70
Polyamide fibre: 0-30
B, on raising base cloth, apply polyurethane coating and make wet half-finished product;
The described polyurethane coating proportioning raw materials by weight of covering is:
100 parts of the poly-carbon copolymer resinses of polyester polyethers
60～140 parts of dimethyl formamides
0～5 part in solvent borne colorant
0～5 part of lignocellulose
0～3 part of acetylbutyrylcellulose
0.5～2 part of anion surfactant
0.5～2 part of non-ionic surface active agent
0～20 part of fire retardant
C, the wet half-finished product that step b is made are carried out the release liners decorative pattern and are shifted, and obtain ultra-soft sofa furniture leather by kneading subsequently.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention selects to contain the raising base cloth of viscose glue composition, and flexibility is good.
2, adopt the poly-carbon copolymerization polyurethane resin of polyester polyethers in the polyurethane coating of the present invention, solved then not weather-proof, the weather-proof then not soft technical problem of traditional PU slurry softness.
Below the invention will be further described by the specific embodiment:
The specific embodiment
The characteristics of the production method of present embodiment ultra-soft sofa furniture leather are to operate as follows:
1, selects to contain the raising base cloth of viscose glue composition
Viscose glue proportioning by weight is
Viscose glue: 30-100
Terylene: 0-60
Cotton: 0-70
Polyamide fibre: 0-30
2, on raising base cloth, apply polyurethane coating and make wet half-finished product;
The described polyurethane coating proportioning raw materials by weight of covering is:
100 parts of the poly-carbon copolymer resinses of polyester polyethers
60～140 parts of dimethyl formamides
0～5 part in solvent borne colorant
0～5 part of lignocellulose
0～3 part of acetylbutyrylcellulose
0.5～2 part of anion surfactant
0.5～2 part of non-ionic surface active agent
0～20 part of fire retardant
3, the wet half-finished product that described step 2 is made is carried out the transfer of release liners decorative pattern, obtains ultra-soft sofa furniture leather by mechanical kneading subsequently.
In concrete the enforcement, raising base cloth can be the single face napping, also can be two-sided napping, and for the single face napping, polyurethane coating is coated in it and rises on the matte.
After tested, the pliability of product of the present invention can reach 9.2～9.8mm, and durability is that jungle is tested five weeks, ten weeks, and more than ten weeks, is equivalent to actual use 5 years, 10 years, more than 10 years.
Table 1 is then lower for proportioning example, the good more intensity of viscose glue content superelevation pliability of viscose glue composition in the base cloth;
Table 2 is polyurethane coating material proportion example, can produces the different functionalities furniture leather according to need.
Table 1
Table 2
Table 2 explanation:
One, SPM-05, KCW are the polyurethane resins with poly-carbon ester copolymerization of polyester polyethers of different modulus;
Two, SPM-05 manufacturer: big Japanese ink chemical industry strain formula can be made the place of production: Japan;
Three, KCW manufacturer: Beyer Co., Ltd, the place of production: Germany:
KCW is 100% solid content, uses with DMF melt into 20% solid solid content in the production.
