Description
Technical field
The utility model relates to field of leather, particularly relates to a kind of organosilicon suede.
Background technology
Superfine fiber fabric is made up of nylon superfine fiber and polyurethane two parts, and wherein superfine fibre is woven into three-dimensional netted, forms the structure being similar to dermal collagen fiber, plays skeleton structure and supporting role; The polyurethane being wrapped in fiber surrounding not only enhances this three-dimensional network, and gives base cloth breathable moisture permeability by the three-dimensional space gap structure of its prosperity.
Carry out flour milling process and dyeing process to base cloth, obtain superfine fibre suede artificial leather, approximate natural leather in its structure, have good breathable moisture permeability, feel is smooth plentiful, wear-resisting, and mechanical strength is excellent.Product quality is soft, has both had feel and the velvet of natural leather, and at smell, elasticity, TENSILE STRENGTH, wear-resisting, COLOR FASTNESS and to go out the aspects such as sanction rate outstanding than corium, can be used for the various fields such as gloves, shoemaking, case and bag, gift ornamental.Because suede does not have resin coatings, although gas permeability and flexibility fabulous, comfortable and easy to wear, water proofing property, dust tightness are all poor, comparatively difficult when the later stage maintains.
Organosilicon material is the inorganic main chain be made up of-Si-O-elementary cell, and side chain is then connected by the various organic group of silicon atom and other, has had both the performance of inorganic material and organic material.Compare polyurethane material, the most outstanding properties of organosilicon material is the characteristics such as the low and physiological inertia of high-low temperature resistant, weatherability, electric insulation, low surface tension, cohesive energy, can give the advantage of organosilicon artificial leather in environmental protection, hydrophobic, anti-soil, submissive, crease-resistant, ageing-resistant and high-low temperature resistant etc.But this also brings many shortcomings.Such as, organosilicon material mechanical strength is poor, is difficult to balance the contradiction between ABRASION RESISTANCE and gas permeability; Low-surface-energy causes being easy to sticky ash; The high feel caused of coefficient of friction is not smooth.
For improving organosilicon leather in gas permeability, existing a kind of base cloth two sides all has dip-coating to have the thickness of open-celled structure to be the silicon rubber dip-coating layer of 1 ~ 3mm, but is difficult to guarantee ABRASION RESISTANCE and sticky ash.In addition, there is technology to adopt in liquid silastic, add thermal expansion capsule, in baking process, produce the pore of opening, breathe freely and waterproof, but may be to take into account wear-resisting and smooth feeling.Also have the sodium chloride of technology addition 100 ~ 200 order granularity in liquid silicon rubber composition, after being heating and curing, boiling removes sodium chloride repeatedly in the hot water.This synthetic leather is ventilative and water resistance is excellent, but can be detrimental to ABRASION RESISTANCE equally.
Utility model content
Based on this, be necessary to provide that a kind of ABRASION RESISTANCE is strong, good permeability and the good organosilicon suede of smooth feeling.
A kind of organosilicon suede, comprise leather substrate, described leather substrate has upper surface and lower surface, and the inside of described leather substrate has open-celled structure;
In the upper surface of described leather substrate and lower surface, a face is had at least to form tapetum.
Wherein in an embodiment, the thickness of described tapetum is 0.01 ~ 5mm.
Wherein in an embodiment, containing silicone fluid silastic-layer in described leather substrate, described silicone fluid silastic-layer forms described open-celled structure.
Wherein in an embodiment, described leather substrate adopts islands-in-sea bicomponent fibre nonwoven layer as substrate, and silicone fluid silicon rubber is distributed in the silicone fluid silastic-layer being formed in described islands-in-sea bicomponent fibre nonwoven fabric and have open-celled structure.
The organosilicon suede that the utility model relates to, adopts the inside of leather substrate and tapetum and leather substrate to have open-celled structure and makes the intensity of organosilicon suede, gas permeability and poisture-penetrability all have lifting, also provide smooth plentiful feel.
The organosilicon suede that the utility model relates to, the thickness of described tapetum is 0.01 ~ 5mm, and this thickness provides best smooth plentiful feel.
The organosilicon suede that the utility model relates to, containing silicone fluid silastic-layer in described leather substrate, described silicone fluid silastic-layer forms described open-celled structure, liquid silastic itself is without harmful fugitive constituent, solvent is not used in recombination process, produce without waste water, and organic silicon rubber is wrapped between the fiber after being dispersed in fibrillation more closely, gap structure is more complicated abundant, organic silicon rubber surface energy is low, stain resistance is strong, plays water proof anti-soil effect to tapetum, reduces later maintenance maintenance worried.
The organosilicon suede that the utility model relates to, described leather substrate adopts islands-in-sea bicomponent fibre nonwoven layer as substrate, silicone fluid silicon rubber is distributed in the silicone fluid silastic-layer being formed in described islands-in-sea bicomponent fibre nonwoven fabric and have open-celled structure, makes the performance of organosilicon suede reach optimum state.

Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the utility model is described further.
Silicone fluid silicon rubber in following examples is all that model is XB1510 purchased from Dongguan City Xi Bo rubber Co., Ltd.
Embodiment 1
A kind of organosilicon suede, see Fig. 1, comprise leather substrate, described leather substrate adopts islands-in-sea bicomponent fibre nonwoven layer as substrate, described leather substrate has upper surface and lower surface, containing silicone fluid silastic-layer in described leather substrate, namely silicone fluid silicon rubber is distributed in the silicone fluid silastic-layer being formed in described islands-in-sea bicomponent fibre nonwoven fabric and have open-celled structure, makes the inside of described leather substrate have open-celled structure; In the upper surface of described leather substrate and lower surface, have at least a face to form tapetum, the thickness of described tapetum is 0.01mm.
Organosilicon suede described in the present embodiment adopts following physical foaming process prepare and obtain:
First, islands-in-sea bicomponent fibre nonwoven fabric is immersed in silicone fluid silicon rubber; Then, the nonwoven fabric extruding after dipping is lost part silicone liquid silastic, after baking-curing, obtains Ji Bu; Finally, by the upper surface of the base cloth containing silicone fluid silicon rubber through frosted process, see Fig. 1, and arrangement of dyeing obtains organosilicon suede.
