mainly used before the function regarding
The initial solvent technology should be to increase that dry process in the adhesive strength in the adhesive layer, the minute solvent technology should be to increase that dry surface layer regarding solvent puffiness. 1. 4 surface treatment surface treatment is actually an increasing number of attention to be a technology, it really is used casino shoe leather, shoe leather will also be used. The techniques can end up being divided directly into printing, spraying, special coating, multi-roller coating, are a good way to increase that added value products. one particular. 4. 1 Printer Printing executed by PU set roller tube the most commonly used surface treatment processes. In addition to the leather surface in the printing to color, gloss and various changes in the role, but additionally to alter the surface texture improvements, such since wax feeling a sense of pink wax, mud velvety, even feel, that synthetic set surface feel more for instance leather.straw hat
There is a two-component surface treatment real estate agent, can raise the scratch opposition surface layer. In addition, functional a finish technology, to improve the surface of PU set light firmness, flame retardant, waterproof, mildew etc .. 1. 4. 2 multifunction printer roller covered PU set processing lower volume sizing, wet pounds generally only 10-40g/m2, a group of effects is actually difficult to display. Roller coating technology is often a multi-function set surface treatment technology from the development of a maximum degree of wet pounds of sizing around 350g/m2, particular treatment may produce influences, such because the very shiny surface colour, only coloured lines protruding segments Crown dye, only regions of the pitch lines painted to the valley dye, mirror coating, a particular touch etc ..newsboy cap
These particular effects will be the printing processing can not be achieved, and therefore many manufacturers for a strong fascination with this technologies. 1. 4. 3 special coating straight coated by using pre in addition to post treatment points. To dry before coating, pre-coating the release paper to the method regarding surface treatment agent, explained pretreatment; post-processing comes from the semi-finished leather in the PU coating to the surface treatment agent straight methods. Coating technology is normally used directly because of the rubbing feed handling needs in the product. This technique is mainly used before the function regarding textile digesting, such as the introduction of waterproof, breathable fabric and cosmetic materials, PU set surface treatment in the application regarding less.
one particular. 4. 4 bottle of spray coating method is introduced in the leather digesting technology, plus it has an exceptionally special impact of surface color in addition to surface consistency, but right now use a lot fewer synthetic set processing. one particular. 5 embossed embossed artificial leather technology very popular method, that may increase product varieties, both in the wet PU set embossed directly to the product will also be carried out in the dry film after which you can embossed. Currently there is a new embossing techniques, namely that transfer which has a release report pattern approach. Embossed which has a roller as well as flat, are unable to press out the fine, trivial lines. Relieve paper approach is rapid, and that pattern might be transferred into the release report PU set surface. This technique of mineral water vapor permeability regarding dry film process compared to small.fedora hats
