Abstract
一种超亲水涤纶织物的硫酸制备方法，将涤纶织物放入稀硫酸溶液中浸渍10min，同时进行震荡，然后取出涤纶织物，在800W的红外灯下照射或在100oC下烘焙7－9min，取出涤纶织物用水冲洗、晾干，即得到超亲水涤纶织物。与现有方法用紫外线照射，涤纶织物需要照射700min才会使水的接触角有一定下降，以及在涤纶织物吸附了纳米二氧化钛后紫外线照射60min后织物才亲水的方法相比，用本发明方法制备超亲水涤纶织物的速度大幅度提高，并且所得超亲水涤纶织物具有耐久性。同时，成本低，不需要使用亲水整理剂。A sulfuric acid preparation method for super-hydrophilic polyester fabrics. The polyester fabrics are immersed in dilute sulfuric acid solution for 10 minutes, and shaken at the same time, and then the polyester fabrics are taken out, irradiated by 800W infrared lamps or baked at 100 o C for 7-9 minutes , take out the polyester fabric, rinse it with water, and dry it to obtain a super-hydrophilic polyester fabric. Compared with the existing method of irradiating with ultraviolet rays, the polyester fabric needs to be irradiated for 700min to make the contact angle of water have a certain decline, and compared with the method that the fabric is only hydrophilic after 60min of ultraviolet irradiation after the polyester fabric absorbs nano-titanium dioxide, the method of the present invention The speed of preparing the superhydrophilic polyester fabric is greatly improved, and the obtained superhydrophilic polyester fabric has durability. At the same time, the cost is low, and there is no need to use a hydrophilic finishing agent.
Description
Technical field
The present invention relates to the Textile Engineering technical field, particularly relate to a kind of sulfuric acid preparation method of super hydrophilic dacron.
Background technology
Terylene has outstanding stiffness, pincher elasticity, can " wash and wear ", and in textile garment industry, industry, have very widely and use.Terylene accounts for about 60% in " five large synthetic fibres ", is most important chemical fiber plus material.
Although terylene has very important application in the textile garment industry, terylene is hydrophobic fabric, and is not hydrophilic, and not affine with skin, wearing comfort is poor, and therefore, international and domestic research about the dacron hydrophilic modification is very many.Report that maximum is terylene plasma modification method.Other method also has potassium permanganate oxidation method, dacron surface deposition nano-oxide method, grafting range protein method, alkali decrement method, ultraviolet irradiation, ultraviolet nanometer titanium dioxide method, Ozonation etc.In actual production, adopt high molecular weight hydrophilic finishing agent finishing method to produce hydrophilic dacron more, still, the hydrophilic dacron washing durability that obtains is poor, does not have durability.
Therefore, exploitation technology new, that can prepare fast the super hydrophilic dacron with durable hydrophilic property will have huge application prospect.
Summary of the invention
The object of the present invention is to provide a kind of sulfuric acid preparation method of super hydrophilic dacron.The method was compared with former method, and the speed for preparing super hydrophilic dacron increases substantially, and preparation time significantly shortens, and the dacron of preparation has Superhydrophilic, and its water contact angle is 0
o, and have durability.
Technical scheme of the present invention is: dacron is flooded in certain density dilution heat of sulfuric acid, then carry out modification, endowing terylene fabric Superhydrophilic under infrared radiation or under certain stoving temperature.Its principle is: the dilute sulfuric acid on dacron surface, under the ultrared effect or under certain stoving temperature condition, moisture content is gradually after the evaporate to dryness, the only remaining a small amount of concentrated sulfuric acid in dacron surface, the concentrated sulfuric acid is under the ultrared heat effect or under certain temperature action, with the large molecule generation of the polyethylene terephthalate sulfonating reaction in the terylene, endowing terylene fiber surface sulfonic group, thereby endowing terylene fabric Superhydrophilic.
The sulfuric acid preparation method of a kind of super hydrophilic dacron of the present invention, realize by following steps:
Dacron is put into dilution heat of sulfuric acid dipping 10 min, shake simultaneously, then take out dacron, irradiation or 100 under the infrared lamp of 800W
oCure 7-9min under the C, take out the flushing of dacron water, dry, namely obtain super hydrophilic dacron.
Further, the concentration of dilution heat of sulfuric acid is 5-8g/L.
Advantage of the present invention is:
Dacron is stained with first after the dilute sulfuric acid, shines or cures processing with infrared ray, and dacron only needs 7-9min can become the Superhydrophilic dacron, and the contact angle of water is 0
oShine with ultraviolet ray with existing method, dacron need to shine 700min just can make the contact angle of water that certain decline is arranged, and after dacron has adsorbed behind the nano titanium oxide ultraviolet ray irradiation 60min fabric just hydrophilic method compare, the speed for preparing super hydrophilic dacron with the inventive method increases substantially, preparation time significantly shortens, and the super hydrophilic dacron of gained has durability.Simultaneously, cost is low, does not need to use hydrophilic finishing agent.
