Abstract
The invention relates to a full grain microfiber and a manufacturing method. The process flow comprises the following steps: a. selecting a microfiber base material; b. transferring the microfiber base material by using release paper as a carrier; c. picking PU (polyurethane) resin; d. pasting the PU resin on the microfiber base material by using an adhesive; and e. plasticizing and separating the pasted microfiber base material and the PU resin to obtain the microfiber finished product. According to the full grain microfiber and the manufacturing method provided by the invention, the abrasion resistance is good, the hydrolysis resistance is strong, the fabric resilience is good, folded lines are fine and smooth, and the leather feeling is strong, thus the full grain microfiber can be used for advanced swimming suits and raincoat jackets.
Description
Technical field
The present invention relates to the manufacturing approach of leather, ultra fibre of especially a kind of wholegrain face and manufacturing approach.
Background technology
Because the reinforcement of the restriction that receives natural conditions and the reinforcement, particularly environmental protection consciousness of the countries in the world consciousness of watching for animals, the use of natural leather is minimizing year by year.Synthetic leather is the best substitute of natural leather, and China is the big country of one 1,300,000,000 population, and according to not exclusively calculating, present domestic synthetic leather aggregate demand surpasses 800,000,000 m
2/ year, and keep ascendant trend, wherein the annual requirement to the high-quality synthetic leather of high-performance can reach 200,000,000 m
2More than.And common synthetic leather is bigger with the natural leather difference on the pliability of feel and texture, and particularly feel is very poor.
At present, existing superfine fiber chemical leather, near natural leather, recovery is poor, scrimp is fineless and smooth, kishke feel is not strong but exist on its feel pliability and texture.
Summary of the invention
The technical problem that the present invention will solve is: in order to overcome the above-mentioned middle problem that exists, a kind of recovery is strong, scrimp is fine and smooth and kishke feel is strong ultra fibre of wholegrain face and manufacturing approach are provided.
The technical solution adopted for the present invention to solve the technical problems is: ultra fibre of a kind of wholegrain face and manufacturing approach, and its technological process:
A. select ultra fine base material: ultra fibre is meant the The Nomenclature Composition and Structure of Complexes of simulation natural leather and can be used as the plastic products of its substitute material; Usually the nonwoven fabric that has flooded is a lamina reticularis, and the microvoid polyurethane layer makes as grain layer, and its positive and negative are all quite similar with leather; And has certain gas permeability; Than ordinary people fabricate-leather more near natural leather, through according to hypodermal colour to the processing of dyeing of ultra fine base material, the processing of finalizing the design at last;
Ultra fine lining is meant the lining that is made into by superfine fibre; Generally we call superfine fibre to the fiber of fiber number below 0.3 dawn; Ultra fine lining is comfortable, attractive in appearance, warming, ventilative; Drapability box richness is preferably arranged, also is being significantly improved aspect hydrophobic and the soil resistance, utilize specific area greatly and soft characteristics can design that different institutional frameworks makes it to absorb more sunlight heat energy or the body temperature that scatters and disappears sooner to effect cool in summer and warm in winter.Full grain refers to keep and use the leather of the original surface of animal skins (one side of growth hair or squama), also is obverse leather.The surface of full grain is without covering with paint, lacquer, colour wash, etc. less direct use, and great majority for example fall line, embossing etc. through beautifying covering with paint.The wounded or disabled few high-grade raw material skin of ingredient requirement that full grain is used; And processing request is also high, belongs to high-grade leather, and intactly is retained on the leather because of the surface of leather; Its strong performance is good; The full grain leather surface is very thin without covering with paint, lacquer, colour wash, etc. or covering with paint, lacquer, colour wash, etc., and has kept the resilient flexible and the air permeability and good of leather, and its manufactured goods are comfortable, durable, attractive in appearance.
B. ultra fine base material is shifted as carrier through release liners: be a kind of prepreg adhesion that prevents, the protection prepreg is not received the separate paper of pollution;
C. select the PU resin: described PU resin is prepared by following weight portion: 100 parts of polyether-type resins, 30～50 parts of dimethyl formamides, 30～50 parts of butanone, 0.1～0.3 part of anti-wear agent, 0.2～0.6 part of corium agent;
D. on ultra fine base material, paste the PU resin through alite paste: described alite paste is prepared by following weight portion: 100 parts of polyamine fat bed material resins, 5～8 parts of bridging agents, 1～3 part of promoter, 10～30 parts of dimethylformamides, 10～30 parts of butanone;
E. ultra fine base material is pasted after plastify, separate, obtain ultra fine finished product with the PU resin.
Selecting the density of ultra fine base material among the described step a is 0.45～0.5g/cm
3
The invention has the beneficial effects as follows: ultra fibre of wholegrain face of the present invention and manufacturing approach, its ABRASION RESISTANCE is good, hydrolytic resistance is strong, recovery is good, scrimp is fine and smooth, kishke feel is strong, can be used as senior swimsuit and charges clothing.
Be described in further detail in conjunction with the present invention now.
Ultra fibre of wholegrain face and manufacturing approach, its technological process:
A. selecting density according to hypodermal colour is 0.45～0.5g/cm
3Ultra fine base material: lamina reticularis and the grain layer of microvoid polyurethane layer by the nonwoven fabric of dipping are formed, through dyeing, the processing of finalizing the design;
B. ultra fine base material is shifted as carrier through release liners;
C. select the PU resin: its surface touch is more near corium, judges and selects corresponding PU resin through ABRASION RESISTANCE and hydrolytic resistance; Next selects the PU resin to prepare by following weight portion: 100 parts of polyether-type resins, 30～50 parts of dimethyl formamides, 30～50 parts of butanone, 0.1～0.3 part of anti-wear agent, 0.2～0.6 part of corium agent;
D. on ultra fine base material, paste the PU resin through alite paste: alite paste is prepared by following weight portion: 100 parts of polyamine fat bed material resins, 5～8 parts of bridging agents, 1～3 part of promoter, 10～30 parts of dimethylformamides, 10～30 parts of butanone;
E. ultra fine base material is pasted after plastify, separate, obtain ultra fine finished product with the PU resin.
Ultra fibre of wholegrain face of the present invention and manufacturing approach can obtain the correction data shown in the following table according to the technological process of above a～e:
| Conventional | Improvement | |
| ABRASION RESISTANCE H-22/1kg/200 time | Broken skin | Normally |
| Hydrolytic resistance 10%NaOH*20 ℃ | Be full of cracks | Behind the 96h 50% |
| Recovery | Difference | Good |
| Turnaround time | 10″ | ?4″ |
| Folding line vestige thickness | 8mm | ?3mm |
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
