Abstract
Synthetic leather (artificial leather) made from artificial fiber has a big difference from genuine skin in property due to a difference between the artificial fiber and the collagen fiber of genuine skin in property. However, the quantity of genuine skin is limited on the one hand, and on the other hand, environmental pollution and large quantities of leftover bits and pieces are caused during the processing of the genuine skin. Limited by production technology, the existing regenerated leather product is relatively hard in hand feel and production process causes pollution to the environment. The utility model provides a compound type imitated skin of collagen fiber. The imitated skin is characterized by consisting of three layers of structure, wherein the first layer is a surface layer constituted by polyurethane synthetic leather, the second layer is a framework layer constituted by synthetic staple fiber, and the third layer is a genuine skin layer constituted by collagen fiber. Compared with the traditional synthetic layer, the imitated skin is strong in skin feel and nice in imitation performance. The imitated skin has softer hand feel than regenerated skin, and the same hand feel, air permeability and physical property with genuine skin.
Description
Technical field
The utility model relates to non-woven material and synthetic leather field, the compound emulation skin of specifically a kind of collagenous fibres.
Background technology
At present, popular leather and fur products has corium and dermatine two big classes on the market.Corium is to adopt animal skins such as ox, sheep to make through complicated tannery.The tanning of leather is exactly with tannin the protein of intracutaneous to be carried out chemistry and Physical Processing, it passes through series of process, and adopt some chemical agents, and make the protein in the animal hides such as ox, pig, sheep that a series of variations take place, make collagen generation denaturation.Tanned leather was both soft, firm, wear-resisting again, was not easy putrid and deteriorated.So tanned leather can be used to make the daily living article of various leathers.And synthetic leather and artificial leather are by weaving cloth base or nonwoven base, are coated with redoubling with polyurethane respectively and adopt special foaming processing to make, and have surperficial feel to exactly like corium, but gas permeability, wearability, cold resistance all are not so good as corium.
Weaving cloth base or nonwoven base all adopt terylene, polyamide fibre synthetic fibers such as (nylon), are processed into through weaving or non-woven operation.The synthetic leather that adopts artificial fiber to make is because the difference of artificial fiber itself and dermal collagen fibre property makes the performance of artificial leather and corium also have very big-difference.But the quantity of corium is limited on the one hand, brings environmental pollution in the corium process on the other hand, also brings a large amount of tailings simultaneously.Utilization again to these tailings mainly is to produce regenerated bark at present, regenerative leather technology is earlier corium fabric, cross filament, resin to be mixed with other auxiliary agent, its technological process is: the hide fiber that corium or regenerated leather raw meal is broken into certain size, and then it is mixed with natural rubber, resin and other raw material, afterwards it is compressed into filter cake; With the filter cake heating, make the fiber fusing on its top layer have stickiness, with each layer extruding, bonding, dehydration moulding, obtain final products after airing, section, embossing and the surface treatment.Existing regenerated bark is owing to the restriction of production technology, and the product feel is harder, and production process produces environment to be polluted.
The utility model content
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and provides a kind of collagenous fibres compound emulation skin, to solve the problem of conventional regeneration skin Boardy Feeling, kishke feel difference, solves the problem of traditional synthetic leather emulation difference.
For this reason, the utility model adopts following technical scheme: compound emulation skin is made up of 3-tier architecture, and ground floor is the superficial layer of being made up of Synthetic Leather; The second layer is the casing play of being made up of synthetic staple; The 3rd layer is the skin corium of being made up of collagenous fibres.
The thickness of ground floor is 0.05-0.2mm, and the thickness of the second layer is 0.3-0.6mm, and the 3rd layer thickness is 0.5-1.2mm.
The beneficial effect that the utlity model has:, good simulation stronger than traditional synthetic leather skin sense have more soft hand feeling than regenerated bark; Have the feel same, air permeability, physical property, can be widely used in sofa, case and bag, clothes, footwear etc. with corium; The preparation method of product described in the utility model is than traditional more environmental protection of regenerated bark production method.
Below in conjunction with specification drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The compound emulation skin of collagenous fibres as shown in Figure 1, it is made up of three-decker, and ground floor is the superficial layer of being made up of Synthetic Leather 1, and the second layer is that the casing play of being made up of synthetic staple is the skin corium of being made up of collagenous fibres 3 for 2, the three layers.Described synthetic staple is selected polyamide fibre or terylene etc. for use.The thickness of ground floor is 0.05-0.2mm, and the thickness of the second layer is 0.3-0.6mm, and the threeply degree is 0.5-1.2mm.
Preparation method of the present utility model is as follows: at first utilize collagenous fibres, employing air lay, heat bonding reinforcement process are made the 3rd layer of emulation skin: the collagenous fibres felt; Again the collagenous fibres felt is carried out online water with the casing play of being made up of synthetic staple on the spunlace non-woven production line and sting compoundly, formed the base material of emulation skin; Base material is carried out the coatings such as dipping, blade coating of polyurethane and handle on synthetic leather production line, form superficial layer, carry out sanding to the 3rd layer again and handle, promptly obtain the compound emulation skin of collagenous fibres.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all falls in the protection domain of the present utility model any simple modification, equivalent variations and modification that above embodiment did.
