Abstract

The invention relates to an anion polyester fiber capable of being dyed at normal temperature and normal pressure, a preparation method and application thereof. The fiber comprises the components of a polyester anion master batch and a polyester chip of which the molecular weight is between 20,000 and 30,000 and which can be dyed at normal temperature andnormal pressure, and the weight ratio is 1-10:90-99. The preparation method comprises the following steps that: (1) the polyester chip is dried and commixed; (2) the polyester anion master batch and the polyester chip are vacuumized; (3) the polyester anion master batch and the polyester chip are mixed, put in an extruder, heated, melted and compressed into a fused mass, and the fused mass is extruded by a rotary screw rod; and (4) matters obtained from the step (3) are sent to a distributing pipe, a static mixer and a metering pump respectively, and pressed in a spinneret, so that a melting current is formed, and the melting current is coated and spun. The fiber can be used for preparing fabrics of wall textile for decoration, working clothes and clothing. The fiber has the characteristics of easy dying, bright color, uniform fiber, high transmission rate of anions, good hand feeling and uniform luster.

Description

technical field [0001] The invention belongs to the field of polyester fiber and its preparation and application, in particular to a normal temperature and pressure dyeable anion polyester fiber and its preparation method and application. Background technique [0002] Polyester (PET) fiber is increasingly valued by people because of its low cost, excellent performance and wide application. Americans began to produce polyester in 1953. In 2006, the global polyester output exceeded 27,000kt, accounting for 67% of the total synthetic fiber output. Polyester has become the most widely used fiber. In recent years, many modification methods have been proposed for PET fibers to make woven fabrics and clothing more comfortable and hygienic to wear. However, for a long time, PET fibers cannot realize the coexistence of multiple functions, which limits the diversification of fabric varieties. In recent years, breakthroughs have been made in the research on PET fiber stylization and...
