Specifically, in step s 701, for animal skin to be processed, the animal skin to conform to a predetermined condition is sorted out.More specifically Say that selection, which is opened a business, is not more than eight feet in ground, that is to say, that whole skin is no more than eight feet, sheep of the Hide thickness no more than 0.9cm Skin, preferably 7-8 feet.Open a business too small, be then unfavorable for cutting and covering chi, more than eight feet, then be unfavorable for cutting (skiving) work Skill, the problems such as easily causing the uneven thickness during skiving.In addition, the density of selection hair belongs to the sheepskin of middle upper density, it is close Degree and fineness require, and fineness determines the glossiness and flexibility of hair, and density determines warmth retention property.

According to the present embodiment, the sheepskin sorted in sort process is the size of 5 to 9 feet (preferably, 7 to 8 feet), On the one hand, the sheepskin size of this scope corresponds between twenty and fifty sheep, when the hair of between twenty and fifty sheep is most soft most fine and closely woven, It is too old not all right too small also not all right, it is necessary to be that the sheep in the between twenty and fifty age just can be with.And in 5 to 9 feet of sheepskin it is to be in The sheepskin of the sheep in season is butchered, when most cold, only put on flesh and does not become mildewed, will butcher after last time shaving and be sent to China. The sheepskin of lint is just grown, is best.

For example, the sheep of South Africa and Australia, done using the two regional sheep has very big advantage with hair epidermis. When season is butchered, the size (for 7 to 8 feet) of sheepskin properly is advantageous to sort for South Africa and Australian sheep, and due to Its latitude reason, temperature is appropriate, is not especially cold.If temperature is especially low, cold weather, then the density of sheepskin can be very Greatly.So the density of the wool of the two local sheep is to belong to middle upper density, fineness upper fineness in being.In addition, South Africa and Australia The sheepskin of big Leah is very light, compared with French sheepskin gently less than one times.Further, since near under the line, hair follicle layering is clear and definite, Cortex is uniform.This also brings great convenience for the skiving processing in later stage.Due to the reasonable control of separation step, according to this reality With the residual rate control of the going out with batt of the epidermis prepared by the preparation method of new embodiment in 2-3%.It is very big excellent to go out residual rate Point.If sorting is good, residual rate can be substantially reduced out.It is whether advanced measurement technology one be important to go out residual rate in the industry Index.Australia Fen Dong Ao Xi Australia, western Australia can further reduce out residual rate closer to equator using the sheep of western Australia.More than It is sort process of the epidermis with batt.

Next, after step S701 separation step terminates, into step S702.In step S702, to what is sorted out Animal skin carries out shortening preservative treatment, and the method for shortening is carried out to animal skin including well known to a person skilled in the art shortening tanning side Method, animal skin is soaked in aqueous and acidleach, reduces the liquid hold-up of the animal skin, by rawhide, also referred to as at blank skin The skin being unlikely to deteriorate is managed into, so as to reach shortening corrosion-resistant purpose.During shortening, heat/pressure/machinery etc. can be used Mode improves shortening speed.

Next, after step S702 shortening step terminates, into step S703.In step S703, filler is utilized Animal skin after shortening processing is filled, is tannin extract according to the filler of the utility model embodiment.However, the utility model Not limited to this,

Traditionally, tannin extract is that the chemical industry as made from the plant material rich in tannin through the step processing such as flooding and concentration produces Product.Usually brown color is to sepia, powdery or bulk.It is mainly used in tanning, is referred to as vegetable tanning agent in curriery.However, In conventional art, it is main tanning agent filling wool leather with tannin extract, is removed from office with tannin extract combination industrial chemicals production hair, the product matte of gained It is coarse, embrittlement, fracture, in industry generally existing tannin extract can not do double-face leather product and give up.

However, in preparation method of the epidermis with batt of embodiment of the present utility model, the evergreen chinquapin of above-mentioned loading has been used Glue is filled, and will fill a certain amount of tannin extract in pending skin, purpose be exactly in order that the leatherware filled have it is certain Fragility, elasticity, in order to follow-up accurate machining (hereinafter machining will be described in detail).

According in Combined Processing of the present utility model, conventionally used brush paints glue, and implementation of the present utility model Example is reduced at double using spray gun spraying point-like, the method for the glue of atomization, dosage.The shortcomings that conventionally used brush version glue is not It is ventilative, perspiration wicking difference.However, using the composite layer good permeability prepared by Combined Processing of the present utility model, and it is whole The density for opening skin spraying is less than 100g, the feature of environmental protection and cost aspect all very advantageous for one square metre.

After sprayed glues, step proceeds to S902, in step S902, contacts epidermis band batt and substrate layer, Apply pressure, while temperature and humidity control.For example, it is directed to four seasons control temperature and humidity.Specifically, control process temperature is less than 70 DEG C, preferably 60 DEG C -70 DEG C；When combining two layers, control pressure, two layers are pressurizeed about 2-4 using air pump and pressed Power；Humidity is controlled to be no more than 75% simultaneously.If humidity is excessive, such as rainwater weather, then need to be dehumidified.Because In fur processing procedure, boiling hot hair processing is being carried out to fur, is scalding and formic acid, collagen adhesion agent is used in hair processing, is also had In the case of alcohol etc. (purpose is in order to which hair is burnt gloss), if running into acidic materials or humidity is excessive, scalded Hair will probably be oxidized, thus can degree of tarnishing become dumb light.

After the above-mentioned Combined Processing with batt and substrate layer to epidermis is completed, step enters S903, in step S903 In, the composite layer after Combined Processing is tiled naturally and cooled, such as tiling after it is quiet put 24-48 hours, so as to reach The effect shaped entirely.

Completely after sizing, the composite layer of preparation can be post-processed, for example, post-processing includes processing line Road, laser scanning, resin film pad pasting, appliqu epsilon embroidery etc..Composite layer after post processing can make substrate layer overlying last layer Decorative layer so that the composite after post processing can be used with two sides.However, the epidermis band hair according to the utility model embodiment Technique after the Combined Processing of layer can not include post-processing step, can be respectively to epidermis band batt and substrate layer system Post-processed respectively when standby, or the post processing can omit as needed and directly.
