Description

High-grade chamois leather mobile phone shell
Technical field
The present invention relates to a kind of mobile phone auxiliary facility, especially relate to a kind of high-grade chamois leather mobile phone shell.
Background technology
Along with the rise of large-screen mobile phone, its resistance to falling property deficiency is the subject matter faced, and be in the demand of the anti-each side such as old attractive in appearance, mobile phone shell has been important mobile phone matching product simultaneously.
Wherein, it is silica gel material greatly that mobile phone shell has, and often makes shades of colour for the purpose of attractive in appearance, but for some high-grade commercial mobile phones, such as Samsung note series, Huawei mate series etc., the normal leather cell-phone cover that uses, to show commercial affairs image.
Chamois leather belongs to the one of suede.Because this matte is that natural suede obtains, so chamois leather of gaining the name through super-dry napping and dyeing.Afterwards, because similar to chamois leather with the matte of pig, sheep, ox-hide production, so be also chamois leather.The fine hair of natural suede is agent structure by base plate, the mixing roll grinding of diamond dust is scribbled through surface, by the reticuloprotein matter snag of leather, the very thin fine hair of one deck is produced on the surface of base plate, the fiber cluster be interweaved through electronic fiber sem observation to its surface, the fiber of end root and fine hair is comparatively thin, this fine and closely woven fiber fur layer appearance style as distinctive in chamois leather---writing effect.
Natural suede, because of the intensive exquisiteness of its fine hair, does not damage minute surface, and cortex is high-grade, is suitable as very much mobile phone shell and uses.But owing to receiving the restrictions such as resource, output, price, natural suede is only limited to rich man and uses in the very long years.For meeting more consumer demands, artificial suede can be used.
The combination that superfine fibre technology and polyurethane resin arrange, makes artificial suede goods all reach the degree being difficult to suede nap distinguish in outward appearance, sense of touch, dyeability and durability etc.Artificial suede also makes many deficiencies of natural suede essence (as washing can be hardening and have contraction); The lack of homogeneitys such as quality, size, thickness, easily become onal, decrease and can utilize part.But its colorfastness is poor, easy mouldy grade still has problems.
Performance at present mainly through changing Synthetic Leather slurry is improved, but the technique changing Synthetic Leather slurry poisture-penetrability and resistance to wear is in the market more complicated, and cost is higher, and effect is also not too obvious.
To sum up, the employing artificial suede of the application, as mobile phone shell, meets high-grade, fungi-proofing, the demand of economic dispatch each side.
Summary of the invention
the problem to be solved in the present invention is: common leather cell-phone cover is high-grade not, and manufacturing cost is high, and have sweat stain etc. owing to often using, easily mouldy, the personage of the especially responsive physique of user is caused to the puzzlement in health, and the coloring of common leather and dyefastness are obviously not enough, be unfavorable for the material of the mobile phone shell of stroking gently as long-term hand.
the object of the present invention is to provide a kind of high-grade chamois leather mobile phone shell, described mobile phone shell has the lower casing being connected to mobile phone back, with the upper casing covering described mobile phone top, described upper casing and lower casing connect together on a side and in junction for ease of the flexible structure that upper casing is raised, it is characterized in that, described upper casing and lower casing are made by artificial suede, and described artificial suede is made by being impregnated with synthetic leather slurry on base material, and has antimicrobial component.
further, the fibrous raw material that described base material uses is the long filament obtained by compound sea-island fibre, and wherein island component is PET, and sea component is PS, is approximately 0.01dtex except the line density of single fiber after PS through solvent is molten.
further, the technological process of production is as follows: fabric of island-in-sea type composite ultrafine fiber → one-tenth net → acupuncture → Ji Bu → PVA dipping → dry → dipping Taraxacum rubber slurry → solidify → dissolve sea component → napping → pitch cutting → dyeing and arrangement → artificial suede.
further, the preparation method of described Taraxacum rubber slurry is as follows:
(1) choose Russian dandelion, the root shearing 3-5cm is continued to employ, and then cleans;
(2) root cleaned up is ground into 200-300 object particle in airslide disintegrating mill;
(3) by particle by ultrasonic assistive technologies process 10-15 minute, then extract in supercritical carbon dioxide fluid, temperature 35 ~ 40 DEG C, pressure 25.0MPa, with 95% ethanol for carrying agent, ethanol consumption 30%, dynamic extraction 150 minutes, flow velocity is 250L/h, and extraction obtains Taraxacum rubber;
(4) dandelion cauline leaf is got, pulverized, dried, adding with dandelion cauline leaf mass ratio is 30% hydrogen peroxide of 1:2, soak 60-80 minute, with the disodium phosphate soln of 0.1mol/L, pH value is adjusted to 7-8, then adds 3-4% nano silicon and the 2-4% sericin of dandelion cauline leaf quality, stirring reaction 2-3 hour at 60-70 DEG C of temperature, after suction filtration, washing, in 105-110 DEG C of baking oven, dry 4-5 hour again, obtain modification dandelion cauline leaf;
(5) Taraxacum rubber slurry needed raw material is prepared according to following weight: Taraxacum rubber 35-40, TPUE rubber 40-55, Kathon 2.0-2.5, melamine resin 3.5-4.5, dimethicone 1-3, stearic acid monoglycerides 0.4-0.5, alkali formula aluminium triformate 0.5-0.8, wood powder 0.5-0.7, modification dandelion cauline leaf 4-7, alumina powder 28-30, diatomite 3-8, tetraethoxysilane 5-8 and dimethyl formamide 65-70, first dimethyl formamide is put into reactor, pass into water vapour, be warming up within the scope of 80-100 DEG C, then Taraxacum rubber, TPUE rubber, Kathon and melamine resin is added successively, continue after insulation reaction 2-3 hour, then adjust ph is between 6-7, add other constitutive material, stir, cool to room temperature, filter, discharging.
further, described napping adopts CSM type napping machine, process conditions: cloth speed 30m/min, hydraulic pressure 2.5kg/cm2; Described dyeing adopts supercritical CO2 fluid dyeing equipment, and process conditions: dyeing temperature is 100-105 DEG C, dyeing pressure is 20-22MPa, and dyeing time is 30-40min, prescription: dispersion dyeing agent, liquid CO 2.
beneficial effect of the present invention:
high-grade chamois leather mobile phone shell of the present invention, first the high-end business image that chamois leather is given is met, and it is cheap for manufacturing cost, have again can be antibacterial effect, Taraxacum rubber is selected from Russian dandelion, from natural, and dandelion itself has antibiotic property, Taraxacum rubber has the advantages such as antibacterial, mildew-resistant, deinsectization, dandelion cauline leaf add the viscosity that membership improves slurry, improve the stable performance of slurry, and the two combination makes the artificial suede prepared have the raising of beyond thought colorfastness, is particularly suitable for cell-phone cover industry.
