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 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 ", in textile garment industry, industry, there is application very widely.Terylene accounts for 60% left and right in " five large synthetic fibres ", is most important chemical fiber plus material.
Although terylene has very important application in textile garment industry, terylene is hydrophobic fabric, not hydrophilic, and not affine with skin, wearing comfort is poor, and therefore, the international and domestic research about 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 obtaining is poor, does not have durability.
Therefore, develop technology new, that can prepare fast the super hydrophilic dacron with durable hydrophilic property and will there is 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 is compared with former method, and the speed of 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 there is durability.
Technical scheme of the present invention is: dacron is flooded in certain density dilution heat of sulfuric acid, then under infrared radiation or under certain stoving temperature, carry out modification, endowing terylene fabric Superhydrophilic.Its principle is: the dilute sulfuric acid on dacron surface, under ultrared effect or under certain stoving temperature condition, moisture content is gradually after evaporate to dryness, the only remaining a small amount of concentrated sulfuric acid in dacron surface, the concentrated sulfuric acid is under ultrared heat effect or under certain temperature action, with the large molecule generation of the polyethylene terephthalate sulfonating reaction in 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, realizes by following steps:
Dacron is put into dilution heat of sulfuric acid and floods 10 min, shake simultaneously, then take out dacron, under the infrared lamp of 800W irradiate or 100
ounder C, cure 7-9min, take out dacron water and rinse, dry, obtain super hydrophilic dacron.
Further, the concentration of dilution heat of sulfuric acid is 5-8g/L.
advantage of the present invention is:
After dacron is first stained with dilute sulfuric acid, irradiates or cure processing with infrared ray, dacron only needs 7-9min can become Superhydrophilic dacron, and the contact angle of water is 0
o.Irradiate with ultraviolet ray with existing method, dacron need to irradiate 700min just can make the contact angle of water have certain decline, and dacron adsorbed after nano titanium oxide ultraviolet ray irradiate 60min after fabric just hydrophilic method compare, the speed of preparing super hydrophilic dacron by the inventive method increases substantially, preparation time significantly shortens, and the super hydrophilic dacron of gained has durability.Meanwhile, cost is low, does not need to use hydrophilic finishing agent.
