Process for producing bamboo charcoal polypropylene composite fibers

Abstract

The invention discloses a process for producing bamboo charcoal polypropylene composite fibers. The process comprises the steps of mixing bamboo charcoal micro-powder with polypropylene slices to ensure that the bamboo charcoal micro-powder is uniformly dispersed in the polypropylene slices; extruding the mixture by using a twin-screw extruder to obtain bamboo charcoal master batches; mixing the bamboo charcoal master batches with polypropylene slices; heating and drying the mixture under the protection of an inert gas; spinning the mixture through a melt spinning machine; and applying oil, and molding by coiling, thus obtaining the bamboo charcoal polypropylene composite fibers. Therefore, by adopting the process for producing the bamboo charcoal polypropylene composite fibers, the prepared fibers has high extensibility, small difference of wet strength and dry strength, high strength, good shaping stability and capability of improving the durability of a fabric; the fabric has high sunlight resistance and high fluffiness, and the added bamboo charcoal has the functional characteristics of adsorbability, antibiosis and the like, so that the process is simple for preparation, reduces the production cost, and is suitable for large-scale batch industrialized production.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a production process of bamboo charcoal polypropylene composite fibers. Background technique [0002] With the development of human society and the advancement of science and technology, people gradually have higher requirements for the beauty of decoration and clothes. Manufacturers also pay more attention to the development and application of fibers. Generally, the functionality of fibers is improved by means of physical modification, chemical modification, and molecular design to obtain fibers with specific properties, so that the original chemical fibers can be used in light and heat. Stability, conductivity, flame retardant, dyeing, antistatic, moisture absorption, fluffy, anti-pilling, anti-fouling and other aspects have been greatly improved. China is very rich in bamboo resources. Bamboo is easy to obtain, easy to process and widely used. Using old bamboo as raw material,...
