Oligomer remover for polyester fiber material |
abstract |
An oligomer removing agent for polyester-based fiber materials comprises a polyester copolymer which is obtained by polycondensation of a dibasic acid component containing 15-65 mol% of a sulfonate group-containing dibasic acid and a dihydric alcohol component containing polyethylene glycol with a molecular weight of 900-3500, and which has a 200°C melt viscosity of 5000-23,000 mPa·s and has 10-40 mass% polyoxyethylene chains in the molecule. The oligomer removing agent is able to overcome the problems caused by deposition of polyester oligomers, when added to the dyeing bath in a dyeing step for polyester fiber materials or for fiber materials that are composites thereof with other fiber materials. |
