Abstract
The utility model relates to a collagenous fiber knitted fabric composite imitated leather which is sequentially provided with a regenerated leather base fabric layer composed of collagenous fibers, a bonding layer, a knitted fabric skeleton layer and a resin surface layer from bottom to top, wherein the knitted fabric skeleton layer is of a structure that yarns are bent to form circles and mutually strung and sleeved; at least one resin inner layer can be additionally arranged between the resin surface layer and the knitted fabric skeleton layer; and the bonding layer of a single-layer or double-layer structure is a bonding surface or is formed by bonding points. Compared with the prior art, the composite imitated leather disclosed by the utility model has the advantages that knitted fabric is adopted to serve as the skeleton layer to guarantee the ductility, the elasticity and the strength of the composite imitated leather, so that the composite imitated leather can be used for manufacturing leather goods which need a certain elasticity and ductility in all directions and have complex surfaces and complex shapes, such as bags and suitcases and the like.
Description
Technical field
The utility model relates to nonwoven material and synthetic leather field, be specifically related to the compound emulation skin of a kind of collagenous fibres knitted cloth, it can directly be used for being manufactured with all directions all need to have certain elasticity and ductility, have the leathercraft of complex-curved and complicated shape, as case and bag etc.
Background technology
At present, the leather substance on the market mainly comprises artificial leather, corium and regenerated bark.Artificial leather mainly refers to artificial polyurethane, its low price, but gas permeability is poor, and comfort level and feel are far away from corium, and material therefor is non-renewable, be unfavorable for the protection of resource, and the feature of environmental protection are poor.Corium is the embodiment of high-quality life, the fine and smooth high resilience of its feel, and good permeability, but expensive, and the nursing trouble.Regenerated bark is that the leftover pieces with corium are that the raw material manufacturing obtains, and its production method can adopt the production technology described in CN102660814A and the CN102660844A Chinese patent; Regenerated bark has the physical property that approaches with corium, on the price but far below corium, and environmental protection, but regenerated bark does not have the epidermis outward appearance that natural corium has, need more with thin artificial leather layer carry out compound could be as finishing material, as a kind of collagen fiber reducing leather described in the CN201785643 U Chinese patent.
But the intensity of regenerated bark is lower than natural corium, the compound emulation skin that itself and artificial leather thin layer composite obtain often need increase one deck casing play between regenerated bark and artificial leather thin layer, as superfine fibre cloth, plain and drillipg, increase the bulk strength of compound emulation skin, avoiding compound emulation skin in use after pressurized or the tension non-response distortion to take place, is 201220595549.6,201220595292.4 and 201220596486.6 Chinese patents about compound emulation skin as the application number of application before my department.But, superfine fibre cloth, plain, drillipg etc. are as the defective of casing play: ductility, elasticity and feel all are inferior to natural corium, be not suitable for making all directions all need to have certain elasticity, ductility and intensity, have complex-curved and leathercraft complicated shape.
At the shortcoming of existing compound emulation skin pliability difference, be necessary to develop a kind of compound emulation skin with elasticity, ductility and intensity.
Summary of the invention
The utility model technical issues that need to address are to provide a kind of collagenous fibres knitted cloth compound emulation skin, be used for making all directions all need to have certain elasticity and ductility, have complex-curved and leathercraft complicated shape, as case and bag etc.
The utility model technical issues that need to address are achieved through the following technical solutions:
The compound emulation skin of a kind of collagenous fibres knitted cloth is characterized in that: it from bottom to top is provided with regenerated bark base cloth layer, tack coat, knitted cloth casing play and resin epidermal area that collagenous fibres are formed successively.Adopt knitted cloth as casing play, guaranteed ductility and the elasticity of compound emulation skin.
Described knitted cloth casing play has the crooked lopping of yarn and goes here and there the structure of cover mutually.This structure can realize between the yarn of enhancement layer pining down each other, and then makes compound emulation skin have certain elasticity and ductility in all directions, also has certain intensity simultaneously.
Be provided with one deck resin internal layer at least between described resin epidermal area and the described knitted cloth casing play.The setting of resin internal layer can further improve the surface elasticity of compound emulation skin.
The number of plies of described resin internal layer is two-layer.
Described tack coat is individual layer or double-decker, constitutes for adhesive surface or by bonding point.
Described bonding point is rhombus.
The lower surface of described regenerated bark base cloth layer has been provided with batt.Playing batt is to handle by plucking to form fluffing, and it can make compound emulation leatherware that abundant " voluptuousness " arranged.
The upper surface of described resin epidermal area is provided with dermatoglyph and/or printed layers.
The thickness of described regenerated bark base cloth layer is 0.1 ~ 2mm, and the thickness of described knitted cloth casing play is 0.3 ~ 1.8 mm, and the thickness of described resin epidermal area is 0.05 ~ 0.1mm.
The beneficial effects of the utility model are: the utility model has adopted knitted cloth as casing play, ductility, elasticity and the intensity of compound emulation skin have been guaranteed, make this compound emulation skin can be used for making all to need on all directions certain elasticity and ductility, have complex-curved and leathercraft complicated shape, as case and bag etc.
