Abstract
The utility model discloses novel superfine fiber synthetic leather. The novel superfine fiber synthetic leather is characterized by comprising a superfine fabric leather base layer, wherein a water repellency layer is coated on the bottom surface of the superfine fabric leather base layer, and a wet-process PU (Polyurethane) coating and a dry-process PU coating are sequentially coated on the upper surface of the superfine fabric leather base layer from bottom to top. A layer of water drawing agent solution is coated on the bottom surface of the superfine fabric leather base layer in a rolling and printing manner and then is dried to form the water repellency layer; then the special polyurethane resin coating is formed on the upper surface of the superfine fabric leather base layer by a wet-process technology, and various aftertreatment embossing can be directly conducted according to the manner, so that poor embossing grains are avoided; and when the superfine fiber synthetic leather is used as a dry-process mirror surface, the added smooth wet-process coating solves the problem that when the conventional superfine fabric synthetic leather is used as the mirror surface product, the surface is easy to be out of flatness and has large creases.
Description
Technical field
The utility model relates to synthetic leather, refers in particular to a kind of novel microfiber synthetic leather.
Background technology
Superfine fibre huge surface area and strong water imbibition make ultra-fine level PU synthetic leather have the intrinsic moisture-absorption characteristics of natural leather of the ultra-fine collagenous fibres of pencil, no matter thereby microstructure internally, or appearance tactile impression and the aspects such as physical characteristic and people's snugness of fit, can compare favourably with senior natural leather, the aspects such as chemical resistance, quality homogeneity, production and processing adaptability and waterproof, mildew-resistant sex change have more surpassed natural leather.Along with the development of super fine leather technology, super fine leather progressively is applied to the fields such as footwear, automobile, clothes; Simultaneously, luggage leather, furniture leather and groceries use the consumption of leather also in sustained, stable growth.But super fine leather is prone to apparent folding line and seriously reaches the bad problem of embossing lines when doing the dry method minute surface, this in a lot of domain restrictions the extensive use of super fibre.
The utility model content
The utility model is for the disappearance of prior art existence, and its main purpose is to provide the better novel microfiber synthetic leather of a kind of embossing effect.
For achieving the above object, the utility model adopts following technical scheme: a kind of novel microfiber synthetic leather, it is characterized in that: comprise microfiber leather basic unit, this microfiber leather basic unit coated on bottom side is covered with a water repellent layer, and microfiber leather basic unit upper surface is coated with wet method PU coating and dry method PU coating from the bottom to top successively.
After the utility model adopted technique scheme, its beneficial effect was: the bottom surface of microfiber leather basic unit is applied one deck with the method for roll marks pull out aqua, then dried the formation water repellent layer; Then the upper surface in microfiber leather basic unit adopts wet processing to form special polyurethane resin coating, in the process of setting of wet processing, reduced the surface tension of microfiber leather basic unit bottom surface due to water repellent layer, checked the formation of capillary effect and pressure differential, make shipwreck to enter from the bottom surface, the exchange of water in DMF in coating and solidification liquid is only carried out in coat side, can effectively avoid coating to get blister, guaranteed quality, and because there is water repellent layer at the back side of the microfiber leather wet method PU of basic unit coating leather finished product, certain moistureproof ability is arranged also.Know that to sum up it can directly do various post processing embossing, solved the bad problem of embossing lines, when doing the dry method minute surface, the smooth wet-process coating that increases has improved the surface irregularity and the large problem of folding line that are prone to when original super fibre is done the minute surface product.
Description of drawings
Fig. 1 is the sectional view of the embodiment of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is elaborated: be illustrated in figure 1 as a kind of novel microfiber synthetic leather of the present utility model, it is characterized in that: comprise microfiber leather basic unit 1, this microfiber leather basic unit 1 coated on bottom side is covered with a water repellent layer 2, and microfiber leather basic unit 1 upper surface is coated with wet method PU coating 3 and dry method PU coating 4 from the bottom to top successively.
Of the present utility model focusing on applies one deck to the bottom surface of microfiber leather basic unit 1 with the method for roll marks and pulls out aqua, then dry formation water repellent layer 2; Then the upper surface in microfiber leather basic unit 1 forms the polyurethane resin coating with wet-process coating technique, in the process of setting of wet processing, reduced the surface tension of microfiber leather basic unit 1 bottom surface due to water repellent layer 2, checked the formation of capillary effect and pressure differential, make shipwreck to enter from the bottom surface, the exchange of water in DMF in coating and solidification liquid is only carried out in coat side, can effectively avoid coating to get blister, guaranteed quality, and because there is water repellent layer at the back side of the microfiber leather wet method PU of basic unit coating leather finished product, certain moistureproof ability is arranged also.Know that to sum up it can directly do various post processing embossing, solved the bad problem of embossing lines, when doing the dry method minute surface, the smooth wet-process coating that increases has improved the surface irregularity and the large problem of folding line that are prone to when original super fibre is done the minute surface product.
The above, it is only preferred embodiment of the present utility model, be not that technical scope of the present utility model is imposed any restrictions, therefore every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment does.
