1. Production of Hemp Grey Yarn Hemp gray yarn is a color-spun yarn developed in the 1980s. It is made of a blend of black and white fibers. And the content of colored fiber is different, divided into dark, medium and light. The proportion of dark fiber is greater than 50%, and the proportion of lig...

Compact spinning is a new spinning technology for spinning on an improved new ring spinning frame. The spinning mechanism is mainly: a condensing zone is added before the traction device of the ring spinning frame, which basically eliminates the spinning and twisting triangle between the front rolle...

Rotor spinning is one of the open-end spinning methods. It is called rotor spinning because of the use of a rotor to condense single fibers. At the beginning, airflow was mainly used, also known as air spinning. Rotor spinning is the process of opening the fed fiber strips into single fibers by a re...

Concentration spinning is a new type of spinning technology in which a concentrating device is added before the drafting device of the ring spinning frame to perform spinning. The spinning mechanism is mainly: a fiber aggregation zone is added before the traction device of the ring spinning frame, a...

Different spinning technology has different effects on the physical properties and appearance of the yarn, and even makes the characteristics of the final product different. At present, the five practical spinning processes of ring spinning, cluster spinning, rotor spinning, air-jet spinning and vor...

1. Reasonable configuration of opening and cleaning, carding and combing processes The effect of reducing the content of short linters on the quality of spinning products. Because in the drafting and floating zone, those shorter fibers cannot be effectively controlled, and large shift deviations are...
