Abstract
The present invention provides a kind of superfine fibre flannelette artificial leather and preparation method thereof with bacteria resistance function, the present invention uses compound prescription, using zinc pyrithione as host agent, with the use of nano zine oxide auxiliary agent, greatly reduce the MIC value of compound prescription, it can reach higher fungistatic effect using less dosage, this antibacterial technology allow to be applied in superfine fiber artificial leather.
Description
(1) technical field
The present invention relates to artificial leather fields, and in particular to a kind of superfine fibre flannelette artificial leather with bacteria resistance function
And preparation method thereof.
(2) background technique
Currently, the high extreme direction development of artificial leather synthetic leather positive functionization.Product variety multiplicity, application field subdivision,
Meet customer requirement more comprehensively, service performance is more prominent, this is also the new standard that market proposes artificial leather synthetic leather enterprise.
Wherein bacteria mildew-proof functionalization is the relatively good direction of industry development prospect, and the research and application of corresponding bacteriostatic agent will be at
For the research hotspot of technical field, but current bacteria mildew-proof artificial leather is backward in technique, most of bacteria mildew-proof processing
It is the general industries mould inhibitor such as the phenols added in a manufacturing process, aldehydes, purpose is intended merely to guarantee material in the short period
Inside not mildew, i.e., it is so-called " passive antibacterial processing "；Antibacterial material is as a kind of emerging functional material, in addition to can guarantee material itself
Not by harmful microbial attack, moreover it is possible to which the personal safety of user is protected in the invasion for enduringly resisting external microorganism, i.e., so-called
" actively antibacterial processing ".
(3) summary of the invention
To realize actively antibacterial target, researcher has carried out a large amount of experiment, and it is original antibacterial to be successfully realized holding
The active bacteriostasis property of artificial leather is improved while anti-mold effect.
Technical scheme is as follows:
A kind of superfine fibre flannelette artificial leather with bacteria resistance function, is prepared as follows to obtain:
By superfine fibre flannelette artificial leather base fabric in the treatment fluid containing nano zine oxide, zinc pyrithione and adhesive into

8g/L；
The nano zine oxide, zinc pyrithione, adhesive can be commercially available by conventional route；
Described adhesive is palyacrylate binder；
The partial size of the zinc pyrithione is in 50-1000nm；
The partial size of the nano zine oxide is in 20-500nm；
The temperature of the dry heat treatment is 130 DEG C (crosslinking temperature of i.e. above-mentioned adhesive), time 1-5min.
In the present invention, the superfine fibre flannelette artificial leather base fabric the preparation method comprises the following steps:
(a) fabric is prepared by raw material of sea-island fibre；
Figured type or unfigured islands-in-sea fiber can be selected in the sea-island fibre, and the fiber number of the sea-island fibre is 1D-3D,
Island component is terylene or nylon, and marine origin is divided into terylene；
The fabric is made by sea-island fibre by opening the technique of packet, lapping, needle thorn/spun lacing consolidation, the table of gained fabric
Sight density is 200-500g/m2；
(b) fabric obtained by step (a) is subjected to heat shrink process processing；
Specifically, the method for the heat shrink process processing are as follows: fabric is immersed in 95 DEG C of hot water and keeps 20min i.e. complete
It is handled at heat shrink process；
The apparent density of semi-finished product obtained by the step is 240-700g/m2；
(c) semi-finished product obtained by step (b) are subjected to polyurethane and are impregnated with process；
The polyurethane impregnation process contains soaking technology containing soaking technology and second including first；
Described first contains soaking technology, and immersion liquid contains the water-soluble polyester of 17-25wt.%, and 100-150 DEG C of drying temperature；
Described second contains soaking technology, and immersion liquid contains the aqueous polyurethane of 10-30wt.%, and 100-150 DEG C of drying temperature；
(d) semi-finished product obtained by step (c) are successively washed, fibrillation, dyeing, mill skin process, is obtained described super
Fine fibre flannelette artificial leather base fabric；
Specifically, the washing process, i.e., wash removal water-soluble polyester with hot water (70~95 DEG C), usually rushed with hot water
Wash 5-30min；
The fiber opening process, using the aqueous solution of 2-20g/L sodium hydroxide as fibrillation liquid, the temperature of fibrillation processing is 90-130
DEG C, the time is usually 15-45min, can remove the extra large part of sea-island fibre by fibrillation, leaves the fibre bundle of island portion point；
Disperse dyes, acid can be selected according to the type difference of fiber in the specific such as liquid flowing dyeing technique of the dyeing
Property the dyestuffs such as dyestuff, direct dyes dyed, dyeing processing carries out in liquid-flow dyeing machine, and the condition of dyeing can be according to raw material
Difference be adjusted；
The mill skin technique carries out on decorticating mill, and using the leatheroid abrasive band of 80-600 mesh, speed is 2-10 ms/min.
The beneficial effects of the present invention are:
The present invention uses zinc pyrithione and zinc oxide as bacteriostatic agent and realizes the bacteria resistance function of artificial leather.Zinc pyrithione conduct
Bacteriostatic agent once widely used in daily chemical product, but since it may cause Human keratinocytes and melanocyte
Heat shock simultaneously causes DNA damage, therefore its usage amount is no more than 1.5%.Zinc oxide is also wide as the representative of inorganic bacteriostatic agent
It is general in coating industry, building material industry is widely utilized.But (minimum development prevents the MIC of two kinds of above-mentioned bacteriostatic agents
Concentration) it is higher, so usage amount is higher in the case where exclusive use, apply the post-processing in superfine fiber artificial leather
When, will cause artificial leather elasticity be deteriorated, pliability be deteriorated situations such as.
The present invention uses compound prescription, using zinc pyrithione as host agent, is used cooperatively nano zine oxide auxiliary agent, greatly reduces multiple
The MIC value (can reach higher fungistatic effect using less dosage) for closing formula, allows this antibacterial technology super
It is applied in fine fibre artificial leather.
