Description

Outdoor water-proof antibiotic superfine fiber chemical leather and its method for sorting
Technical field
The present invention relates to the afterfinish method of suede superfine fiber synthetic leather.
Background technology
In recent years, suede superfine fiber synthetic leather increasingly liked by consumer, becomes superfine fiber chemical leather Main product, at the same time, feature super fiber leather gradually climbs up stage, and the one seat of occuping market.As people are to family Chasing after for outer activity is high, the requirement to outdoor protective articless also more and more higher, especially protective footwear and protective gloves, it is desirable to anti- The functions such as water, ventilative, antibacterial, wear-resisting, scratch resistance.Existing water proof type super fiber leather and antimicrobial form super fiber leather commercially extensively flow OK, but outdoor water-proof antibiotic super fiber leather technology and unstable.
Initially, the Final finishing technology bathed altogether using C8 waterproofing agents and antibacterial, can reach requirement, but contain in C8 The harmful substances such as PFOA and PFOS, do not meet consumer's environmental protection concept, therefore C8 products are not gradually contained PFOA's and PFOS C6 products replace.
But fact proved, C6 waterproofing agents and antibacterial bathe altogether Final finishing technology and unstable, different batches of product it is anti- There is larger difference between water and antibacterial effect.
The content of the invention
It is an object of the invention to provide a kind of outdoor water-proof antibiotic superfine fiber chemical leather and its method for sorting, with gram Take the defect of prior art presence.
The method of the present invention, comprises the steps：
(1) superfine fiber chemical leather is immersed and will be padded in treatment fluid, after padding, the liquid carrying rate of super fiber leather is 50%～ 70%；
Described treatment fluid includes the component of following parts by weight：
PH is 4～6；
Preparation method is as follows：
By the mixing of C6 water-proof aagents, waterborne antibacterial agent, water cross-linking agent and water, then the pH of mixed liquor is adjusted with acetic acid, Obtain described treatment fluid；
Preferably, superfine fiber chemical leather is immersed in treatment fluid, is rolled through 4 leachings 4, the liquid carrying rate for controlling super fiber leather is 55%～65%, regulation speed is 5～8m/min；
(2) and then by the product of step (1) at 130～160 DEG C 5～15min of drying and processing, then cooled down, received Volume.
(3) by the super fiber leather of step (2), on three printing machines, roller coat oiliness antibacterial, the positive and negative of super fiber leather is respectively applied One time, it is desirable to which roller coat amount is 2-10g/m2, then dry at 120 DEG C, finally cooled down, wound；
The operations such as described cooling, winding are known method, can be found in document：Qu Jianbo. synthetic leather material and technology Learn [M]. Beijing：Chemical Industry Press, 2015. methods recorded.
The C6 water-proof aagents are perfluor hexane sulfonyl compound or sulfonate, the such as AFH6 of Rudoiph company, Du Pont Teflon SLA, the TG-5671 of big King Company in one kind or arbitrary proportion mixture aqueous solution；
The waterborne antibacterial agent is silver ion type inorganic composite, and such as Rudoiph's antibacterial AGP, Hensel steps antibacterial HeiQ The mixture aqueous solution of one kind or arbitrary proportion in Pure TF, Tao Shi antibacterial ET；
The water cross-linking agent is aromatic series closed type polyisocyanate, and the such as FU of solar corona company or Shanghai think to contain polymer One or two the mixture of the water dispersed isocyanate cross-linking agent EC-600 of material；
The oiliness antibacterial is macromolecule organic antibacterial agent, the such as ATE's 9280, DOW Chemical of Germany Herst One or two mixture in SKANE ò M-8.
Agent of the present invention is combined using Organic-inorganic composite antibacterial, and product has the high efficiency of organic antibacterial agent, holds Continuous property has safety and the thermostability of inorganic antiseptic again；There is good water resistance again using C6 waterproofing agents, i.e. environmental protection.
Gained super fiber leather can reach following effect：
Water absorbance≤30%, penetration by water amount≤0.2g, vapor permeation amount >=5mg/cm2H (testing standards ISO 20345)；Meanwhile, the effect of anti-K. pneumonia can reach more than 90% (testing standard ATCC 4352), resist golden yellow The staphylococcic effect of color can reach more than 90% (testing standard ATCC 6538).
The super fiber leather steady quality of the method production, overcome waterproof and antibacterial can not while reach the defect of standard, and And product air-and water-permeable vapour is good, scratch resistance strong, is well suited for for outdoor protective footwear and protective gloves.
