INFRARED-ABSORBING TEXTILE MATERIALS AND DYEING PROCESS FOR IMPARTING INFRARED-ABSORBING POWER

摘要

The invention provides a dyeing process for imparting infrared-absorbing power which does not need a larger amount of a black dye for attaining a higher infrared-absorbing power even when a dyeing process capable of realizing small lot production is employed and which enables dyeing even in non-black colors. A dyeing process for imparting infrared-absorbing power which comprises immersing a nylon or wool textile material in a dye bath comprising a mordant dye selected from among Mordant Black 601 (trade name: a product of Yamada Chemical Co., Ltd.), C.I. Mordant Black 7, C.I. Mordant Black 11, and C.I. Mordant Black 51 and a chromium-containing dye selected from between C.I. Acid Blue-158 and C.I. Acid Blue-193 and subjecting the resulting textile material to iron mordanting and which can attain such dyeing as to bring about an infrared reflectivity of 30% or below in a wavelength region of 800 to 1000nm.
