A kind of fiber raw liquid color paste and preparation method thereof

Abstract

The invention discloses a method for preparing a novel environment-friendly fiber stock solution color paste. The color paste is prepared from pre-emulsion liquid wrapped with pigments, adipic hydrazide aqueous solution and initiator solution as raw materials. When adding monomers and initiator solution The temperature is controlled at 55-60°C, and the reaction is carried out for 4-5 hours after the addition is completed, and the method of batch addition is adopted. The fiber stock liquid color paste obtained by the present invention has more excellent coloring effect, excellent color fastness to light, and color fastness to weathering, and does not require chemical dyeing, tow dyeing or gel dyeing of subsequent fibers or fabrics, and reduces pollution of the environment.

Description

technical field

[0001] The invention belongs to the technical field of fine chemical coatings, and in particular relates to a preparation method of a novel environment-friendly fiber stock solution color paste. Background technique

[0002] With the continuous expansion of environmental hazards, under the social background of depleting energy and water resources and increasing pressure on environmental protection, how to avoid high energy consumption and high pollution in the printing and dyeing process is an important issue related to the survival of the textile industry. In the traditional coloring process of fiber raw materials, the exhaustion rate of cationic dyes is low, the dye consumption is high, and the environmental pollution is serious; at the same time, due to the structural reasons of the dyes, it is difficult to accurately match colors; The color fastness, soaping color fastness and rubbing color fastness are poor. Due to the relatively low price and convenien...
