Abstract

The invention relates to an anion terylene colored fiber and preparation and preparation and application thereof. The fiber comprises the following components: a terylene anion master batch, a terylene colored master batch and a terylene fiber-forming polyester chip, and the weight ratio is 1-10:1-10: 80-98. The preparation comprises the following steps that: (1) the terylene fiber-forming polyester chip is dried in vacuum, the anion powder is mixed with the chip, and the obtained mixture is subjected to melt extrusion, cooling and granulation; (2) the terylene anion master batch, the terylene colored master batch and the terylene fiber-forming polyester chip are vacuumized, heated and subjected to heat preservation; (3) the raw materials are put in an extruder and heated, melted and compressed; and (4) the obtained product is sent to a distributing pipe, a static mixer and a metering pump respectively to form a melting current, and the melting current is cooled, coated and spun to obtain the finished product. The anion terylene colored fiber is flexible and elastic, resembles the wool fabric in style, maintains the characteristics of lightness and smoothness of terylene, can transmit anions and has different colors; moreover, the preparation method has the advantages of simple operation, easy realization of production process, low dyeing cost and the suitability for industrialized production.

Description

technical field [0001] The invention belongs to the field of polyester colored fiber and its preparation, in particular to an anion colored polyester fiber and its preparation 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 the improvement of negative ion performance, ...
