Abstract

The invention relates to a leveling agent used in ramie fabric liquid ammonia solvent dyeing and a preparation method and application method thereof and belongs to the technical field of textile chemistry. N-hydroxymethyl acrylamide is dissolved in a proper amount of deionized water to prepare an N-hydroxymethyl acrylamide solution; acrylic polyether with the polymerization degree being 45 is dissolved in a proper amount of deionized water to prepare an acrylic polyether solution; under the stirring condition, the temperature is controlled to be 79-81 DEG C, the N-hydroxymethyl acrylamide solution, the acrylic polyether solution and an ammonium persulfate initiator solution are simultaneously and slowly added into a four-mouth flask containing a certain amount of deionized water dropwise, dropwise adding time is controlled to be 2-3 h, and the temperature is preserved for 3-4 h after dropwise addition; finally, cooling is conducted to prepare the leveling agent. The weight-average molecular weight of the leveling agent is 10000-20000. The leveling agent prepared through the method is used in ramie fabric liquid ammonia solvent dyeing, the color of dyed fabric is uniform, and the dyeing defect is avoided.

Description

technical field [0001] The invention belongs to the technical field of textile chemistry, and in particular relates to a leveling agent in liquid ammonia solvent dyeing of ramie fabrics, a preparation method and an application method thereof. Background technique [0002] The textile industry is a traditional pillar industry of my country's national economy and an important livelihood industry. It is also an industry with obvious international competitive advantages. Ramie fiber is one of the main raw materials for textile fabrics and occupies an important position in textile fabrics. my country is one of the countries with the richest hemp resources in the world, mainly including ramie, sisal hemp, flax and jute kenaf, etc. Among them, ramie is widely planted in my country because of its fast growth rate, high yield and easy survival. The fabric made of ramie fiber has the advantages of breathability, moisture absorption and perspiration, and is an ideal summer high-grade c...
