Problems solved by technology

In addition, in order to make the second mercerizing effect slightly uniform, it is necessary to squeeze water, dry and rewind the yarn after the first mercerizing, and then shake the yarn. Such repeated processing steps not only increase the production cost, but also increase the yarn density. Loss, the loss of rewinding is more obvious for fine count yarn

Abstract

The invention relates to a dual mercerized yarn and a processing method of the dual mercerized yarn. The dual mercerized yarn belongs to the technical field of spinning. The method comprises steps of processing to obtain a mercerized fiber through liquid caustic soda or liquid ammonia under tensile force; processing the mercerized fiber by spinning and singeing, and mercerizing twice, so as to obtain the dual mercerized yarn. The mercerized is uniform in mercerization, sufficient in color and glass, and good in dyeing effect; and difference of degree of twist and count can be avoided during a yarn mercerizing process; phenomena of a non-uniform part in mercerizing or 'surface mercerizing', a dyeing effect in dyeing after mercerizing, and color differences can be avoided; and a shortcoming that cost, loss and drained sewage are increased due to a conventional complicated dual yarn mercerizing technology can be overcome.

Description

technical field [0001] The invention relates to the technical field of textiles, and relates to a double mercerized yarn and a processing method thereof. Specifically, the fiber is first subjected to liquid alkali or liquid ammonia mercerizing treatment, and the mercerized fiber is conventionally spun into yarn, and then the yarn is burned. The processing methods of wool, shaking yarn, mercerizing, dyeing, drying and rewinding and the double mercerized yarn formed. Background technique [0002] Yarn mercerizing is a mature processing method, which can give the yarn a silky feel and luster, and is mostly used in high-end knitted and woven fabrics; mercerized cotton has become the best in cotton and the first choice for high-end brands. However, the first mercerizing of the yarn still has some phenomena such as not bright and full luster, uneven local mercerizing or "surface mercerizing". In view of this, dyeing and finishing workers have been trying to make up for the above d...
