Description
Technical Field
The invention belongs to the technical field of blended yarn preparation, and particularly relates to a preparation method of a Sorona fiber and Xinricel fiber blended yarn.
Background
Because the grain problem restricts the development of natural fiber and the energy problem (the chemical fiber takes petroleum as raw material) restricts the development of chemical fiber, the development of novel biomass fiber can realize that the chemical fiber raw material gradually gets rid of the excessive dependence on petroleum and realizes sustainable development. On the basis, in order to reduce the dependence on petroleum resources and reduce the emission of greenhouse effect gases, the DuPont company in the United states provides a leading bio-based polymer (namely, Sorona polymer) platform.
37% of the raw materials are from plants which can be recycled and regenerated every year, and simultaneously, the method has excellent environmental protection characteristics. Compared with the production process of the nylon 6,
the energy consumption is reduced by 30 percent, and the emission of greenhouse effect gases is reduced by 63 percent. Compared with the production process of nylon 6,
the energy consumption is reduced by 40 percent, and the emission of greenhouse effect gases is reduced by 56 percent.
As a breakthrough new bio-based polymer solution, the polymer can provide superior performance and superior design freedom, and is widely applicable to various application fields. Based on
The advantages and the application universality of the method, the application of the method in the textile industry field is widely regarded.
The research on Sorona in the market is mainly focused on the field of filaments, and the research on short fiber yarns is less. Based on the particularity of the appearance and structure of the Sorona fibers, related researches mainly focus on combining the characteristics of the Sorona fibers and other fibers, and blending the Sorona fibers and the other fibers into yarns according to a certain proportion to improve the spinnability and the performance of fabrics. According to the traditional spinning process, Sorona fibers need to be spun into yarns through the working procedures of opening and picking, cotton carding, drawing, roving, spinning and the like. The fibers should be pretreated prior to carding. Meanwhile, in the opening and picking process, the opening and picking machine group is usually adopted to carry out carding and striking on the fibers for multiple times, and the Sorona fibers are low in breaking strength and easy to brittle fracture and are easy to break after being struck by a mechanical beater to form a large amount of short fibers. In addition, in the carding process, Sorona fibers are beaten for multiple times through a licker-in, a carding plate, a cylinder, a cover plate and a doffer of a carding machine, and particularly, the fibers are beaten for multiple times through carding by needle teeth of the cylinder and the cover plate in working areas of the cylinder and the cover plate, so that the fibers are seriously damaged. Aiming at the problems, the patent adopts an SX01 type test fiber slivering machine based on the rotor spinning principle and the structural design to carry out the carding slivering of Sorona fibers so as to smoothly manufacture raw slivers.
The Sorona fiber has the advantages of reproducibility, environmental protection and the like, and the Neocel fiber has the advantages of good moisture absorption and air permeability, wearing comfort, short production process flow, low energy consumption, wide raw material source, environmental protection in production and the like. Therefore, in order to respond to the national green and environment-friendly requirement, the application potential of Sorona is better excavated, the application range of the Sorona is expanded, more performances are endowed to the yarn, and the research on the blending process between the Sorona fiber and the Xinricia fiber is particularly important.
