Abstract

The invention discloses a preparation method of a single-component fiber. An obtained PBT functional fiber has high elasticity, high strength, wear resistance, light resistance, rapid suction and discharge performance, high simulation performance and the like, and also has good dyeing performance, so that the PBT functional fiber has a great improvement space in aspects of appearance design, handfeeling and performance; the market demand of the PBT functional fiber is further expanded; and insufficiency of relevant research is filled through the development of the PBT functional fiber. The data and research foundation is provided for further development and utilization of the PBT functional fiber.

Description

technical field [0001] The invention belongs to the field of fiber materials, and in particular relates to a method for preparing single-component fibers. Background technique [0002] PBT is the abbreviation of polybutylene terephthalate. PBT fiber has good durability, dimensional stability and good elasticity, and the elasticity is not affected by humidity; there are many methods for preparing PBT fiber, among which melt spinning The silk method is one of the most widely used in industrial production. There are many parameters in the melt spinning process. These parameters determine the process of fiber formation and the structure and properties of the spun fibers. In production, the fibers with the required properties are obtained by controlling these parameters. According to the process, the main spinning parameters controlled in production can be summarized as melting conditions, spinning conditions, solidification conditions, winding conditions, etc., among which the ...
