Problems solved by technology

However, because the surface of the fiber is extremely smooth and the hollowness is extremely high, the linear density of the fiber is very small and the fiber quality is very light; and because the fiber has no curl and the surface is extremely smooth, the friction coefficient of the fiber is low. If there is no good cohesion between the fibers, the flocs cannot be smoothly formed between the fibers, and the sliver can be spun smoothly, which brings a lot of trouble to the application of the fibers in the textile industry.
[0003] At present, there are very few studies on crystal cotton (crown melon) fiber in the textile field, mainly because the fiber is too thin and too short to be spun by traditional spinning techniques.

Abstract

The invention relates to a friction-weight increasing agent as well as preparation and application thereof to crystal cotton fiber spinning. The friction-weight increasing agent is mixed solution of a high molecular polymer, an emulsifying agent, a softening agent, inorganic metal salt, an anionic surfactant and a nonionic surfactant. In the preparation method, the friction-weight increasing agent is formed by emulsifying and stirring the raw materials. The application method comprises the following steps: treating the crystal cotton fiber at the temperature of 20-30 DEG C by utilizing the friction-weight increasing agent; and then balancing for 12-48 hours under the condition of constant temperature and humidity to obtain friction-weight increased crystal cotton fiber. According to the invention, the operation method is simple, the raw materials are cheap, the cost is low and better energy-saving effect is achieved because of operation at normal temperature, and the preparation method and the application method are ecological friendly and environmental friendly and easy for industrialized production; and the obtained friction-weight increased crystal cotton fiber has the advantages of better cotton carding, slivering and spinning performances, thus breaking through the spinning bottleneck problem of the crystal cotton fiber in the textile field.

Description

technical field [0001] The invention belongs to the field of friction and weight increasing agent and its preparation and application, in particular to a friction and weight increasing agent and its preparation and application in crystal cotton fiber spinning. Background technique [0002] Crystal cotton (crown melon) fiber belongs to Asclepiaceae and is widely distributed in tropical and subtropical regions of Asia and Africa. The fiber has natural antibacterial, disinfectant, and medicinal effects. At present, the research on crystal cotton (Crow's horn melon) mainly focuses on the analysis of pharmacological activity, and it is a new type of natural, environmentally friendly and hygienic fiber raw material. Because the fiber has soft luster and excellent softness, it has good potential application value in the textile field. However, because the surface of the fiber is extremely smooth and the hollowness is extremely high, the linear density of the fiber is very small a...
