Problems solved by technology

[0004] The fiber belongs to cationic modified polyester and can be dyed with cationic dyes. However, when it is used in color spinning, it has the defects of low dyeing depth and undyed Porel fiber is easily stained and discolored during washing after spinning and weaving. Porel fibers cannot be dyed with cationic dyes in spinning production
At the same time, Porel fibers can also be dyed with disperse dyes, but Porel fibers have a hollow honeycomb structure. After dyeing with disperse dyes, the floating dyes in the hollow parts are difficult to clean, and this structure is very easy to absorb floating dyes. The color spun yarn made is very easy to stain and change color when washed, so it cannot be dyed with conventional disperse dyes
In addition, during the fiber dyeing process, the original oil agent of the fiber has been completely cleaned, and then after high temperature and high pressure, the original performance and feel of the fiber have undergone great changes: the strength of the colored fiber has decreased significantly, and the length of the fiber has appeared to varying degrees. shrinkage, the specific resistance increases geometrically, and the hand feels soft, astringent or slippery, which makes the spinnability of the dyed fiber very poor

Abstract

Disclosed is novel Porel fiber colored spun yarn. Loose fibers of raw materials used in the Porel fiber colored spun yarn contain, by weight, at least 30-100% of Porel fibers which include the colored Porel fibers, and the colored Porel fibers are obtained by being dyed in high-washing fastness dispersing dye with ester groups in a dyeing step of the loose fibers of the raw materials in a colored spun yarn spinning process. Through modification of a Porel fiber dyeing process, dyed fiber products are produced with fastness meeting the requirements, complete chromatography and bright colors, and spinnability is improved by improving of the process.

Description

technical field [0001] The invention relates to a functional textile, in particular to a novel polyester cotton-like fiber melange spinning yarn and a production method thereof. Background technique [0002] my country's textile and chemical fiber industry is in a new stage of transformation, upgrading, innovation and development, and the cotton gap problem has become a difficult problem restricting the development of the industry. In order to alleviate the shortage of natural fibers such as cotton, the state will further develop a new generation of high-simulation differentiated and functional fibers, and promote new high-value-added, super-simulation fabric fabric products, as a joint promotion of textiles and chemical fibers during the "Twelfth Five-Year Plan" period. an important strategic task. [0003] At present, the super imitation cotton fibers in the market are natural yarn varieties. Due to the limitations of dyeing and spinnability, they have not been effectivel...
