Description
Technical field
The leather material of surface layer production is granulated the present invention relates to the artificial grain layer processed by very thin collagenous fiber bundle, by the people
Material.
Background technique
Leather is common product in people's daily life, currently, leather mainly includes leather and simulated leather." corium
Leather " refers to the product made of animal dermis, with the development of industry, it has been developed that the simulated leather of many forms, simulated leather
It usually uses cloth made of chemical fibre as substrate, then is covered with paint, lacquer, colour wash, etc. with PU, PVC or other resinous materials in the one side of the above substrate
Or the method for paste layer, a kind of product in appearance like leather is made, this kind of product is also referred to as: artificial leather, synthetic leather etc..
" leather " is to form tool after a series of physics and chemical process processing with the skin stripped down with animal
There is certain acidproof, alkaline-resisting, wet-hot aging performance leather.It eliminates almost all of non-fibrous material, maintains collagenous fiber bundle
Original woven condition and structure.
Say that leather is divided into two layers from level: grain layer and lamina reticularis, the collagenous fibres in grain layer and lamina reticularis
Beam either fineness degree, compactness extent and type of weave is different, and the collagenous fiber bundle of grain layer is thin, and grain layer is by subreticulate
Laminated collagenous fibres beam diameter is generally at ten microns hereinafter, grain layer is got over closer to the laminated collagenous fiber bundle of epidermis
Carefully, it knits that angle is smaller closer to the collagenous fiber bundle of epidermis in grain layer, and is gradually parallel to the surface of epidermis, fiber
It weaves also even closer.
During processing leather, after epidermis and hair removing, grain layer surface shows roughness, likeness in form cream
Head, so grain layer is also referred to as papillaris pars, therefore, the rough shape of leather is also formed the day of leather finished product
This feature of right decorative pattern；The lamina reticularis collagenous fibres beam ratio grain layer of leather is coarse, the diameter of the collagenous fiber bundle of lamina reticularis
At 20-150 microns and braiding is close, and type of weave is generally divided into three classes: diamond weave, Curved braiding, waveform braiding, because
This lamina reticularis is to constitute and play major part and effect of the leather with mechanics strengths such as tear-proof.Grain layer and lamina reticularis
Between linked together by the collagenous fiber bundle for weaving loosely, also someone is referred to as transition zone.
The component of leather is mainly collagenous fiber bundle, also containing a small amount of other elastomers, reticular fibre, sweat
Gland, blood vessel etc., therefore, the various performances of leather each depend on the grain layer in collagenous fiber bundle, especially leather to people
The compatibility of body, comfort, from extremely fine and smooth collagenous fiber bundle.The process that collagenous fiber bundle is formed is as follows: procollagen
Molecule → protofibril (diameter 1.2-1.7nm) → subfibril (diameter 3-5nm) → fibrinogen (the general 20nm of diameter) → thin
Fiber (2-5 μm of diameter) → collagenous fiber bundle (20-150 μm of diameter).
In to rawhide treatment process, due to being processed the limitation of technique, the grain layer of the leather of meeting after treatment
In there are still elastomer, reticular fibre, sweat gland, blood vessel etc..And Animal Skin all more or less have disability, while
It saves and will also result in certain defect in process, such as stab, asperities, drawn grain, loose side, dyeing defect, therefore, in order to use
Needs, most of leather needs eliminate above-mentioned defect by having a shave, make leather flatness high, smooth, easypro
It fits.
In order to preferably utilize the collagenous fiber bundle in leather, present someone discongests leather leftover pieces etc.,
It is recycled after combing.Collagenous fiber bundle has the characteristics that the more to comb the more thin shorter, and the thinner collagenous fiber bundle the shorter, and branch also gets over
It is more, and merely stated that in the documents such as existing textbook, patent document, paper collagenous fiber bundle combing is imitative to that can make
The state of leather substrate, and always nobody thought or accomplished repeatedly to comb collagenous fiber bundle or by existing slurrying
The fineness that technique makes collagenous fiber bundle reach or approach leather grain layer collagenous fiber bundle carrys out making artificial grain layer, allows artificial
Grain layer and the structure of grain layer in leather and performance are extremely approximate.
In existing technology, " the similar grain layer " seen in simulated leather is made by plastic raw materials such as PU, PVC
It forms, such as discloses a kind of non-woven base of collagenous fibres in the patent document that Chinese Patent Application No. is 201210072419.9
Material surface treatment method, it is first that collagenous fibres nonwoven substrates surface fiber in homogeneous thickness processing is flat thin, reproduce one layer of class
Then grain layer successively carries out water spray light on class grain layer, makes leather lines, processing pliability and flatness, finally uses
Common process does surface color processing to class grain layer and surface is emphasized to handle.The present invention has the advantages that this method avoids often
Rule make face in substrate surface using release paper delivery medium, this product close to corium head layer effect, show leather appearance and
Character, simple process and low cost, product obtained no matter substrate or used in any material reach outlet and it is interior
The environmental requirement for selling market reaches resistance to dry, wet-milling and wipes, and the leathers physical index such as tortuous, cold-resistant complications of resistance to room temperature reaches detection
Wet friction standard 200 times, 4-5 grades of Bearable dry and wet wipe.It also discloses the class grain layer simultaneously to manufacture in accordance with the following methods: by class
Grain layer raw material is equably smoothed out with roll coater in substrate surface, mends roller roller coating 2-5g/sf with scraping for the first time, roller coating the again after doing
It is secondary, with No. 17 roller roller coating 10-20g/sf, it is obvious that the grain layer for making non-leather at present is made of chemical raw material
It forms, using this grain layer, although can copy the grain layer in leather in appearance, its comfort, environment-friendly type etc. cannot
Reach the requirement of grain layer in leather.Moreover, the collagen after never utilization on the books is discongested, combed in the prior art is fine
Dimension beam forms the collagenous fiber bundle close to leather grain layer fineness to make and the extremely approximate people of leather grain layer performance
It is granulated surface layer and its leather substance.
