Description

Modification method of polyester fiber product

The present invention relates to a method for modifying a synthetic fiber product, in particular a polyester-based fiber product, and in particular, an object of the present invention is to have an excellent antistatic property, hydrophilicity, recontamination prevention while maintaining laundry durability.

In general, polyester-based fibers are hydrophobic, so the accumulation of static electricity is good, and this causes not only unpleasant feelings when worn, but also has the disadvantage of being contaminated by adsorbing dust.

Therefore, to solve this problem, many methods have been controlled so far, for example, US Patent Nos. 3012332 and 3738864 which use a mixture of polyepoxide and polyamine, or Japanese special office using epoxide and polyalkylene glycol. 49-18109, and the like. However, these conventional methods have drawbacks such as complicated treatment process or poor durability against washing and deterioration of the original advantages such as coloring, hardening of touch, and strong deterioration.

In addition to the above-mentioned drawbacks, in particular, the antistatic property is not sufficient enough to use a large amount of processing drugs in this case not only economically unreasonable, but also appeared irritating to the skin, there was a problem in practical use.

In addition to the above method, there is a method of polymerizing polymer inside the fiber by swelling the dyed polyester forge and penetrating the hydrophilic processing agent monomer into the swollen polymer. As vinyl monomer is graft polymerized, it needs to be processed in inner gas (N ₂ , steam, etc.) when processing in tenter, so it requires not only a separate steamer-like device but also vinyl monomer. Because of its low chemical preservation, polymerization was easily carried out by heat and light.

The invention of the hydrophilic, antistatic processing method of the polyester fiber product bar will be described first in detail the configuration of the present invention. 0.1-10% of the compound of the general formula [I] and the compound of the formula [II] with respect to the compound of the formula [I]

And glycidyl groups were added 1-5 times to the equivalent of the -OH or -NH ₂ groups present in the compounds of the general formula [I] and [II], and other curing accelerators. Immersed or sprayed textile products in a processing solution made by adding 0.1-1% of water and adding 100% of water or organic solvent, and squeezing the wet pick up to 40-100% to 20 ° C. Drying at -120 ℃ and heat treatment at 130 ℃ -200 ℃ for 1 to 60 seconds to form an antistatic and hydrophilic coating of poorly soluble, poorly soluble to form a reforming method according to the present invention.

Compounds of formula [III] are polyepoxides having at least two glycidyl groups in one molecule.

As a specific example of the processing agent used for this invention, as a general formula [1] compound, polyoxy ethylene glycol, poly (oxyethyl-oxypropylene) glycol, polyoxy ethylenediamine, poly (oxyethyl-oxypropylene) diamine, etc. Are used alone or in combination. Examples of the compound of the general formula [II] include tartaric acid, sodium tartarate sodium-2-hydroxy-1-protan sulfonate,

Examples of the general formula [III] compound include glycidyl ether of bisphenol A, diglycidyl ether of ethylene glycol, triethyl glycol diglycidyl ether, glycerin diglycidyl ether, glycerin triglycidyl ether, and polyethylene.

이하의 부착량으로서도 효과가 우수할뿐 아니라 섬유표면에 난용, 난융성의 피막을 형성하여 세탁, 마찰등에 대해 거의 영구적인 대전방지 및 친수화 효과를 발휘할 수 있는 것이다.The present invention is characterized by the addition of the compound of the general formula [II]. When only the compound of the general formula [I] and [III] is used without using the compound of the general formula [II], the antistatic property is almost Because it does not appear or at least 5% is attached to it, the antistatic effect is required, so the processing cost is high and there is no real commercialization value due to the problem of hardening of the touch and change of color by attaching a large amount of resin. Compared to the case of using the general formula [II], the synergistic effect of the polyoxyalkylene group and the ionic group does not add the ionic group.

Not only is the effect excellent in the amount of adhesion below, but also a poorly soluble and refractory film is formed on the surface of the fiber to exhibit almost permanent antistatic and hydrophilic effects against washing and friction.
