Description

Vynález ea týká sposobu antistatickéj úpravy a úpravy, umožňujúcej íahkú vyprateínosl Spiny u polyesterových vlákien alebo plošných textilných materiálov.The present invention relates to a method of antistatic treatment and a treatment allowing for easy spinning of polyester fibers or flat textile materials.

Z doterajšej praxe sa pre účely úpravy, umožňujúcej íahkú vyprateínosť špiny, soil release úprava, a súčasnú antistatická úpravu, používali kopolyméry kyseliny akrylovéj a estermi kyseliny akrylovej. Táto úprava však vydrží maximálně 7 až 8 pracích cyklov. Pre polyestery ea používajú tiež polyesterétery připravené polykondehzáciou dimetyltereftalátu a etylénglýkolom a polyetylénglykolom. Táto úprava je založená na hydrofilnom charaktere polyetylénglykolového relazca. Jej nevýhoda je v tom, že polyesterétery sú látky voskovitej konzistencie, v dósledku čeho dochádza čiaatočne k zvýšeniu adhézie suchéj pigmentovéj nečistoty. Uvedené nedoetatky odstraňuje sposob nešpinivej a antistatickéj úpravy, u ktorého podstata je v tom, že sa na vlákno, respektive plošný textilný materiál nanesie 0,5 až 6 % hmotn., - počítané na hmotnost - upravovaného materiálu, pleinnomerného kopolyesteru kyseliny tereftálovej β obsahom 5 až 20 % molových kyseliny 5-sulfoizoftálovej na hmotnost upravovaného materiálu a fixuje s® pri teplote 130 až 190 °C, s výhodou pri 150 °C. Navrhovaná pleionoméry a obsahom 5-sulfoizoftálovej kyseliny sa nevyznačujú týmto nedostatkom pri zachovaní soil release účinku. Dalšou výhodou plelonomérov s obsahom kyseliny 5-sulfoizoftálovej je, že ju možno kombinoval a inými typmi úprav: nehořlavé, ántimikrobiáln®, farbenie bázickými farbivami, pričom už náhrada polyesteréterov pleionomérnymi kopolyestermi 5-sulfoizoftálovej ky201238In practice, copolymers of acrylic acid and esters of acrylic acid have been used for the purpose of treating soil dirt, soil release treatment, and the present antistatic treatment. However, this treatment lasts a maximum of 7 to 8 wash cycles. For polyesters ea they also use polyester ethers prepared by polycondensation of dimethyl terephthalate and ethylene glycol and polyethylene glycol. This treatment is based on the hydrophilic nature of the polyethylene glycol chain. Its disadvantage is that the polyester ethers are waxy in consistency and consequently initially increase the adhesion of the dry pigment impurity. The abovementioned non-wastes eliminate the dirty and antistatic treatment, which is characterized in that 0.5 to 6% by weight, based on the weight of the material to be treated, of a pleinomeric terephthalic acid copolyester β containing 5 is applied to the fiber or the textile fabric. up to 20 mol% of 5-sulfoisophthalic acid by weight of the material to be treated and fixed with s at a temperature of 130 to 190 ° C, preferably at 150 ° C. The proposed pleionomers and containing 5-sulfoisophthalic acid do not exhibit this drawback while maintaining the soil release effect. Another advantage of 5-sulfoisophthalic acid-containing plelonomers is that it can be combined with other types of treatments: non-flammable, antimicrobial®, dyeing with basic dyes, replacing polyester ethers with pleionomeric copolyesters of 5-sulfoisophthalic acid201238

Navrhovaný sposob spočívá v úpravě polyesterových vlákien alebo textilií pleionomórnyml kopólyeatermi kyseliny tereftálovej a 5-aulfoizoftélovaJ. Soil release úprava je v tomto případe podmienená prítomnosťou polárných -SO^Na skupin, So súčasne podmieňuje hydrofilný charakter upraveného vlákna, resp. textilu, ako aj jeho antistatické vlastnosti.The proposed method consists in treating the polyester fibers or fabrics with pleionomorphic copolymers of terephthalic acid and 5-sulfoisophthalic acid. The soil release treatment in this case is conditioned by the presence of polar -SO2 Na groups. and its antistatic properties.
