Abstract
The invention provides a method for preparing a super-hydrophilic polyester fabric with sulfuric acid. The method comprises the following steps of: impregnating a polyester fabric in a dilute sulfuric acid solution for 10minutes, simultaneously carrying out shaking, then taking out the polyester fabric, irradiating the polyester fabric with a 800W infrared lamp or baking the polyester fabric at 100 DEG C for 7-9minutes, taking out the polyester fabric, washing the polyester fabric with water and drying the polyester fabric in the air, thus obtaining the super-hydrophilic polyester fabric. Compared with the existing method in which ultraviolet irradiation is used, a certain contact angle of water can be decreased only by irradiating the polyester fabric for 700minutes, and the polyester fabric can be hydrophilic only after adsorbing nano titania and then being subjected to ultraviolet irradiation for 60minutes, the method has the following advantages that the preparation speed of the super-hydrophilic polyester fabric is substantially increased; the obtained super-hydrophilic polyester fabric has durability; and meanwhile, the cost is low and the hydrophilic finishing agents are not needed.
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.
