  • Comparative Example 2 A copolymer (polyester resin) was obtained in the same manner as in Example 1 except that the amounts of components (b) and (c) were changed. More specifically, the example is used except that 123 g of polyethylene glycol (Mw 3000) and 72 g of polyoxyethylene co-alkylmethyl ammonium chloride are used instead of 170 g of polyethylene glycol (Mw 3000) and 24 g of polyoxyethylene co-alkylmethyl ammonium chloride. The condensation reaction was carried out in the same manner as 1 to obtain a target copolymer (polyester resin).
  • Comparative Example 3 Similar to Example 1 except that only 194 g of polyoxyethylene co-alkylmethyl ammonium chloride was used instead of 170 g of polyethylene glycol (Mw 3000) and 24 g of polyoxyethylene co-alkylmethyl ammonium chloride and no polyethylene glycol (Mw 3000) was used. Condensation reaction to obtain a target copolymer (polyester resin).
  • a processing agent for fibers is manufactured using each of the copolymers (polyester resins) of Examples 1 to 3 and Comparative Examples 1 to 3 as follows, and a fiber product (bore fleece) is processed using the same. Thereby producing processed fiber products. Furthermore, the performance of the processing agent for fibers was evaluated by conducting tests on the manufactured fiber products.
  • a polyester bore fleece was used as a processing fiber (fiber product). This polyester bore fleece was immersed in the treatment bath for the above-mentioned processing agent for fibers (durable antistatic agent), squeezed with a mangle at a throttling rate of 70%, and dried with a tenter at 130 ° C. for 4 minutes. Thus, the polyester bore fleece was processed to produce a processed bore fleece. According to calculation results from the amount used, concentration and throttling rate of the processing bath, the processed bore fleece is 0.28% owf, ie, 100 g of bore fleece, the copolymer (polyester resin About 0.28 g).
