Abstract
The utility model belongs to the technical field of leather and particularly relates to breathable type waterborne polyurethane shoe lining leather. The waterborne polyurethane shoe lining leather sequentially comprises an immersed spunlace layer, a waterborne polyurethane connection layer, a waterborne polyurethane foaming layer and a waterborne polyurethane surface layer. According to the breathable type waterborne polyurethane shoe lining leather disclosed by the utility model, various waterborne polyurethane materials are used as main materials and waterborne polyurethane is an environment-friendly material; a plasticizer and an organic solvent are not used in production and use processes, which prevents producers and consumers from being hurt and is friendly to the environment; a product can pass the certification of various environment-friendly quality systems of Europe and America so that trade barriers are eliminated; in a molding process, immersed spunlace is directly compounded and the breathable type waterborne polyurethane shoe lining leather can be directly used after release paper is torn, so that the breathable type waterborne polyurethane shoe lining leather is very convenient; and the air permeability of the immersed spunlace is good so that the air permeability of the whole product is enhanced and the breathable type waterborne polyurethane shoe lining leather is more suitable for being used as a shoe lining material.
Description
Technical field:
The utility model belongs to the leather technology field, refers in particular to a kind of vapor-permeable type aqueous polyurethane footwear leather inside.
Background technology:
Existing footwear leather inside normally adopt oiliness PU material to make, and also just oiliness PU material layer composite material-feeding formation is sewed up or bonding use with cloth in use on its structure.The existing footwear shortcoming of leather inside are: oiliness PU material then contains the DMF(dimethylformamide), plasticiser and DMF are to human body and the harmful material of environment, it causes huge pollution to water, at present its pollution that causes being dealt with wastes time and energy, therefore not only not environmental protection, can't reach the chemical property requirement of American-European part brand, also can bring threat to production work personnel and consumer's health.In addition, the leather gas permeability is poor inside for existing footwear.
The utility model content:
The purpose of this utility model is to overcome the above-mentioned weak point of existing product, and a kind of vapor-permeable type aqueous polyurethane footwear leather inside is provided.
The utility model realizes that the technical scheme that its purpose adopts is: a kind of vapor-permeable type aqueous polyurethane footwear are leather inside, and this aqueous polyurethane leather comprises impregnation spun laced fabric layer, aqueous polyurethane following layer, aqueous polyurethane foaming layer, aqueous polyurethane surface layer successively.
The thickness proportion of described impregnation spun laced fabric layer, aqueous polyurethane following layer, aqueous polyurethane foaming layer, aqueous polyurethane surface layer is 1:1:1:1.
The utility model adopts all kinds of water-base polyurethane materials as material of main part, aqueous polyurethane is environment-friendly materials, all there are not plasticiser and organic solvent in production and the use, can avoid producers and consumer to be endangered, also friendly to environment, product can pass through American-European various environment-friendly quality system certifications, removal of barrier to trade; Directly compound impregnation spun laced fabric during moulding can directly use after tearing off-style paper layer during use, and is quite convenient; The gas permeability of impregnation spun laced fabric is good, and the gas permeability of entire product is strengthened, and is more suitable for as footwear material inside.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Below in conjunction with specific embodiments and the drawings the utility model is further specified.
As shown in Figure 1, vapor-permeable type aqueous polyurethane footwear described in the utility model are leather inside, and this aqueous polyurethane leather comprises impregnation spun laced fabric layer 1, aqueous polyurethane following layer 2, aqueous polyurethane foaming layer 3, aqueous polyurethane surface layer 4 successively.The thickness proportion of described impregnation spun laced fabric layer 1, aqueous polyurethane following layer 2, aqueous polyurethane foaming layer 3, aqueous polyurethane surface layer 4 is good with 1:1:1:1.Its making step is as follows: at first be coated with on the off-style paper layer surface and scrape one deck water-base polyurethane material, its prescription is fit to as the polyurethane surface surface layer, through forming aqueous polyurethane surface layer 1 after the drying and shaping, be coated with the water-base polyurethane material of scraping the another kind of prescription of one deck at aqueous polyurethane surface layer 1 then, its prescription is fit to as polyurethane foam layer 2, the oven dry back forms aqueous polyurethane foaming layer 2, be coated with on aqueous polyurethane foaming layer 2 surfaces then and scrape the water-base polyurethane material that a layer formula has viscosity, as aqueous polyurethane following layer 3, and lay impregnation spun laced fabric layer 4 at aqueous polyurethane following layer 3, dry again and handle typing, peel off release liners and can finish making.
The utlity model has following advantage:
1. with the supporting body of knitted cloth as the sports goods leather, make product have the good and soft characteristic of retractility, be fit to carry out gloves processing;
2. use Polyurethane embossed layer makes product have full feel as the agent structure of water-based sports goods leather, and has good wear-resisting, anti-flexion and weatherability, and its anti-performances such as elasticity, wrinkle recovery effects, resistance to impact of pulling out all significantly improve;
Between the knitting layer of cloth supporting body of sports goods leather and the aqueous polyurethane foaming layer use Polyurethane following layer follow, compound, make product have good peel strength, satisfy access times, requirements such as intensity.
The utility model adopts all kinds of water-base polyurethane materials as material of main part, aqueous polyurethane is environment-friendly materials, all there are not plasticiser and organic solvent in production and the use, can avoid producers and consumer to be endangered, also friendly to environment, product can pass through American-European various environment-friendly quality system certifications, removal of barrier to trade; Directly compound impregnation spun laced fabric during moulding can directly use after tearing off-style paper layer during use, and is quite convenient; The gas permeability of impregnation spun laced fabric is good, and the gas permeability of entire product is strengthened, and is more suitable for as footwear material inside.
