DEEP-COLOR DYED WOOLEN TEXTILE PRODUCT AND PRODUCTION THEREOF

摘要

PURPOSE:To obtain the subject textile product with an unconventional deep color tone by forming a deepened color film composed of a fluorine compound and a nonionic surfactant on the surface of a woolen textile product. CONSTITUTION:Wool fiber is previously subjected to oxidation treatment to partially remove surface cuticular layers and a treating solution containing a fluorine compound (e.g. tetrafluoroethylene-hexafluoropropylene copolymer) and a nonionic surfactant is then applied to the surface of a dyed woolen textile fabric and dried to form a deepened color film assuming a deep color of <=14 L value. Thereby, a woolen textile product of a deep color tone which is not conventionally available can be obtained. For example, an ethylene oxide addition type polyoxyethylene alkyl ether can be exemplified as the aforementioned surfactant.
