Abstract

The invention relates to a silk leather facture. It is characterized in that it adopts the coat of the natural fiber, silk and compositive fiber and the leather and composes them physically. The compositive treatment is to flatten the natural fiber, the silk and the compositive fiber on the surface of the leather and agglutinate them point-to point. The invention is that the silk is flattening fixed on the leather surface, therefore it has enough physical intensity and solidity. The facture is simple, safe and non-pollution.

Description

A kind of preparation method of silk leather

Technical field

The present invention relates to the leather application technology.

Background technology

The use of leather is of long duration, and from the early stage animal skin resisting cold of the mankind, with regard to the suitable society need of marching toward step by step, manufacturing process is more and more fine finishining also to the research of leather.Such as goat, sheepskin, ox-hide, pigskin just cut open into several layers by dried after cuing open processing, have not only improved the utilization rate of leather, simultaneously for the leather body is light, thin, the assurance of the soft material that provides the foundation.On the leather processing program, adopted low alkali swelling, low concentration enzyme normal temperature is softening, use pollution-free stabilizing agent and handle, through detergent washing, leather greasing adds draws a bow to the full, and cover mill, fall technology such as soft, toggling, make product reach ultra-thin, light and soft, the high-grade leather that can wash.Since all kinds of leathers through processing after, the purposes scope of leather is constantly enlarged.Such as present ultra-thin leather thickness only below 0.3～0.4mm, the cold-resistant overcoat that makes leather only can only make footwear, bag, case, wear outward, and move towards the underwear field, family property and home decoration thing thereof etc.Though present leather and fur products is various in style, its superiority is separately arranged, but also there is weak point, such as the thickness of ultra-thin leather below 0.2～0.3mm, the tearing strength of its physics and fastness are also because of the attenuate variation of its thickness, and for example leather is made underskirt, be through the safety and sanitation and the comfort health-care sense that also are not so good as cotton, silk on one's body.

The preparation method that the purpose of this invention is to provide a kind of silk leather, can make with this manufacture method that silk is smooth to be fixed on the surface, light weight, material does not flock together in when wearing, and contacts smoothly, ventilative, soft with skin, and it is comfortable to keep healthy, enough physical strengths and fastness are arranged, its preparation method is easy, and safety is pollution-free.

Technical solution of the present invention is to adopt natural fiber, silk, synthetic fiber fabric and corium to be carried out the physics Combined Processing to form, this Combined Processing is that natural fiber, silk, synthetic fiber fabric are flat on the leathering, be bonded with point type, this point type is that the bounding point of spot distribution on whole composite surface is bonding.

The above point type bounding point is equally distributed point, or the point of uneven distribution.

The skin of the above natural corium is sheepskin, goat skin, ox-hide or pigskin.

Physics Combined Processing below particularly of the present invention is meant the wire mark coating that refers to intaglio plate, and adhesive resin or thermoplastic resin are printed on the lining, is flat on the leathering again, presses or lithographic plate is pressed with hot-rolling, and temperature is being not less than 0.2kg/cm at 70～100 ℃, pressure ², the time is that the overpressure treatment under 0.5～1 second condition forms.

The point of the described point type bounding point of wood invention directly is can be 0.3～0.5mm, and dot spacing also can be that identical, the similar then dot spacing in a footpath is from mutually different uneven distribution from being the evenly distributed of 0.5～0.8mm.

Present ultra-thin leather thickness reaches 0.3～0.4mm, and tearing strength is thereupon thin and reduce, although this ultra-thin leather has light, soft characteristics, but when making underwear, sense organ requires, sanitation performance is not as good as cotton, silk.And silk particularly, quality is light, thin, soft, smooth, ventilative, and contains tens seed amino acids, healthy very useful to the people, and this is a not comparability of leather.Silk is compounded on the leather, this can increase the physical strength and the fastness of ultra-thin leather, gives sense of security of user, gives the comfort of people's silk in addition, and certain function of health care is arranged relatively, so silk leather of the present invention is the dual-use function that has had leather and silk concurrently.

To be that silk is smooth be fixed on the surface advantage of the present invention, and light weight expects not flock together in when wearing, contact with skin smooth, ventilative, softness, it is comfortable to keep healthy, and enough physical strengths and fastness are arranged, its preparation method is easy, safety is pollution-free.

The specific embodiment

With the wire mark coating of polyamide hot with intaglio plate, with being imprinted on the silk face that point type distributes, its some footpath is 0.3mm, and dot spacing is 0.5mm, has the face of glue point to cover on the sheepskin in silk, 70 ℃ of temperature, and pressure 0.2kg/cm ², the overvoltage on roll squeezer of 0.5 second time, polyamide hot promptly solidifies after the overvoltage.

If the inhomogeneous site intaglio plate that adopts the viscoelastic polyurethane gum resin is to ox-hide, and the coating of cotton is compound, and the overvoltage temperature can reach 100 ℃, pressure 0.5kg/cm ², the time can reach 1 second, and then the point of bounding point footpath can reach 0.5mm, and dot spacing is from reaching 0.8mm.

If adopt the EVA of Methacrylamide 70% and methacrylic acid ammonium salt 30%, through being mixed with moisture 20% glue, compound to the coating of pigskin and synthetic fiber fabric with even site intaglio plate, the temperature of Combined Processing, pressure, time are identical with the leather compound condition with silk.

Claims

1, a kind of preparation method of silk leather, it is characterized in that adopting and the lining of natural fiber, silk, synthetic fibers and corium are carried out the physics Combined Processing form, this Combined Processing is that natural fiber, silk, synthetic fiber fabric are flat on the leathering, be bonded with point type, this point type is that the bounding point of spot distribution on whole composite surface is bonding.

2, the preparation method of a kind of silk leather according to claim 1 is characterized in that the point type bounding point is equally distributed point, or the point of uneven distribution.

3, the preparation method of a kind of silk leather according to claim 1, the skin that it is characterized in that the natural corium of indication are sheepskin, goat skin, ox-hide or pigskin.

4, the preparation method of a kind of silk leather according to claim 1, it is characterized in that the physics Combined Processing is meant the wire mark coating with intaglio plate, adhesive resin or thermoplastic resin are printed on the lining, be flat on the leathering again, press or dull and stereotyped the pressure with hot-rolling, temperature is being not less than 0.2kg/cm at 70～100 ℃, pressure ², the time is that the overpressure treatment under 0.5～1 second condition forms.
