Problems solved by technology

In addition, with the fierce competition in today's textile industry market, profits are thinning, some weavers use inferior oil agents, and some weavers add a large amount of oil agents and function improvers because of the high cost of PTT fibers in order to avoid technical risks. This brings some difficulties to the printing and dyeing process. Usually, problems such as color spots, color spots, and oil spots are encountered. hurt

Abstract

The invention discloses a deoiling combination for PTT fiber which comprises the following components by the weight percentage: 55 to 65 portions of polyacrylic acid and maleic anhydride copolymer sodium salt with the molecular mass between 7,000 to 10,000 and 8 to 12 portions of fatty alcohol polyoxyethylene ether. The invention further discloses a deoiling method which can cause PTT fiber to be reacted in solution containing the deoiling combination, wherein, the deoiling combination is 2 to 10 g / L, the liquid alkaline is 10 to 1,400g / L, the temperature is 90 to 100 DEG C, the temperature rise rate is 1 to 8 DEG C / min, the temperature decreasing rate is 1 to 8 DEG C / min, and the processing time is 30 to 70 min. The invention can effectively eliminate oil solutions on the surface of the PTT fiber at the preprocessing phase of the PTT fiber and quickly and effectively eliminate PVA pulp and functional modifying agents possibly existing simultaneously, thereby preventing the abrasion, the color dots, the dyeing defect and other defects of the PTT fiber in the processing procedures such as later dyeing, printing, post-finishing and the like.

Description

technical field [0001] The invention relates to the field of pre-dyeing treatment in the printing and dyeing industry, in particular to a degreasing composition and a degreasing method for PTT fibers. Background technique [0002] Polytrimethylene terephthalate (PTT) is a new type of polyester fiber, which is formed by polycondensation of terephthalic acid (TPA) and 1,3-propylene glycol (PDO). It has excellent elasticity, Softness and dyeing properties. PTT fiber has the characteristics of both polyester and nylon, soft to the touch, full of elasticity, good stretch recovery, elongation as good as spandex fiber, and easier to process than elastic fiber spandex, which is very suitable for textile and garment fabrics. In addition, PTT It also has the characteristics of anti-fouling, anti-static, and easy maintenance. Therefore, in the near future, PTT fiber will gradually replace polyester and nylon, and become a very competitive fiber in the 21st century. [0003] At presen...
