Abstract
The invention discloses cold-pressed pull-up embossed PU leather. The cold-pressed pull-up embossed PU leather comprises a base cloth layer, wherein a polyurethane bonding layer is compounded on the base cloth layer, a water repellent layer is arranged on the polyurethane bonding layer, a color-change layer is compounded on the water repellent layer, a polyurethane surface layer is compounded on the color-change layer, a plurality of cavities are formed between the color-change layer and the water repellent layer, micro-capsules which are ruptured automatically under extrusion are formed in the cavity, and the micro-capsules are filled with sympathetic ink. According to the cold-pressed pull-up embossed PU leather, the loss of the sympathetic ink is reduced and the service life of the pull-up PU leather is prolonged.
Description
Technical field
The present invention relates to a kind of PU to remove from office.
Technical background
Variable color PU is also referred to as the general leather in pula, and it is that a kind of crying in the general oil injection in pula leather is made, because the diffusion of the general oil in pula makes leather color when stressed can produce the effect of a gradual change with diffusion recovery, therefore must be called variable color PU.There is certain transparency on the top layer of variable color PU, and after receiving force-extension effect, the general oil in the pula wherein injected is stressed transfers, use stressed leather to show and lose oiliness, color shoals gradually, and neighbouring varying in size because of active force, the degree losing oiliness is different, forms a kind of aberration.But variable color PU removes from office after being repeatedly subject to force-extension, and color shifting ink wherein easily runs off, thus affects effect and the service life of variable color PU.
Summary of the invention
Technical problem to be solved by this invention is just to provide one and colds pressing burnt discoloration PU leather, can alleviate the loss of color shifting ink, improve the service life of variable color PU leather.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
One cold pressing burnt discoloration PU leather, comprise base cloth layer, on described base cloth layer, compound is provided with polyurethane adhesive layer, on described polyurethane adhesive layer, conjunction is provided with water repellent layer, on described water repellent layer, compound is provided with photochromic layer, and on described photochromic layer, compound is provided with polyurethane cover, is provided with several cavitys between described photochromic layer and water repellent layer, be provided with the micro-capsule of the automatic ulceration that is squeezed in described cavity, in described micro-capsule, be filled with color shifting ink.
Preferably, described micro-capsule comprises the body with spherical inner chamber, and described color shifting ink is filled in intrinsic spherical inner chamber, and the outer surface of described body is provided with has flexible shell fragment, the two ends of described shell fragment are respectively equipped with tartar, and the thorn point of described tartar is arranged towards body surface.
Preferably, described cavity is arranged at the lower surface of photochromic layer or the upper surface of water repellent layer.
Preferably, described cavity is the hemispherical cavity formed between photochromic layer and water repellent layer.
Preferably, described base cloth layer is that the fabric of island-in-sea type nylon ultrafine fiber at 5 ~ 7 dawn is made through polyurethane slurry impregnation by fiber number.
Beneficial effect of the present invention is:
When variable color PU removes from office by force-extension, cavity between water repellent layer and photochromic layer can be squeezed, thus the micro-capsule in cavity is squeezed and ulceration, color shifting ink in micro-capsule flows out colour changes on impregnation layer automatically, thus supplement color shifting ink for photochromic layer is lasting, variable color PU leather can not lose color changeable effect fast because of the loss of color shifting ink, thus extends the service life of variable color PU leather.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described further:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of micro-capsule in the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
As shown in Figure 1, the present invention includes base cloth layer 1, on described base cloth layer, compound is provided with polyurethane adhesive layer 2, on described polyurethane adhesive layer, conjunction is provided with water repellent layer 3, on described water repellent layer, compound is provided with photochromic layer 4, and on described photochromic layer, compound is provided with polyurethane cover 5, is provided with several cavitys 401 between described photochromic layer and water repellent layer, be provided with the micro-capsule 402 of the automatic ulceration that is squeezed in described cavity, in described micro-capsule, be filled with color shifting ink 4022.Described cavity 401 is arranged at the lower surface of photochromic layer 4 or the upper surface of water repellent layer.Described cavity 401 is the hemispherical cavity formed between photochromic layer and water repellent layer.Described base cloth layer 1 is that the fabric of island-in-sea type nylon ultrafine fiber at 5 ~ 7 dawn is made through polyurethane slurry impregnation by fiber number.
As shown in Figure 2, described micro-capsule 402 comprises the body 4021 with spherical inner chamber, described color shifting ink 4022 is filled in intrinsic spherical inner chamber, the outer surface of described body is provided with has flexible shell fragment 4023, the two ends of described shell fragment are respectively equipped with tartar 4024, and the thorn point of described tartar is arranged towards body surface.
Principle of the present invention is:
When variable color PU removes from office by force-extension, cavity between water repellent layer and photochromic layer can be squeezed, the inwall moving contact shell fragment of cavity, the body surface making tartar stab micro-capsule is moved at shell fragment two ends, micro-capsule is thrust and ulceration by tartar, color shifting ink in micro-capsule body flows out colour changes on impregnation layer automatically, thus supplement color shifting ink for photochromic layer is lasting, and the inner chamber of micro-capsule body is spherical, when color shifting ink liquid level to micro-capsule body surface is subject to below the ulceration mouth of tartar's puncture, color shifting ink will no longer flow out, when variable color PU removes from office and stretches by next time, micro-capsule is squeezed impact, color shifting ink will spill on a small quantity, thus long-term colour changes on impregnation layer, variable color PU leather can not lose color changeable effect fast because of the loss of color shifting ink, thus extend the service life of variable color PU leather.
Just preferred embodiment of the present invention is described above, but can not be interpreted as it is restriction to claim.The present invention is not only confined to above embodiment, and its concrete structure allows to change, and those skilled in the art can make various change and distortion according to the present invention, only otherwise depart from spirit of the present invention, all belongs to the scope that claims of the present invention define.
