Description

Technical Field

[0001] The utility model belongs to the technical field of cross-linked lyocell fibers, in particular to a cross-linked lyocell fiber production device. Background Art

[0002] Lyocell fiber has many excellent properties of both natural and synthetic fibers. The raw materials are renewable, the production process is environmentally friendly, the solvents are recyclable, and the pure textile products are naturally degradable. It has the attributes of green and sustainable development. In the environment of advocating green and low-carbon consumption at home and abroad, Lyocell fiber has been widely and deeply used in the three major terminal fields of clothing and accessories, home textiles, and industrial use. The differentiated products of Lyocell fiber mainly include cross-linked, semi-cross-linked, fine denier, special-shaped, zero-carbon, matte and other categories; functional products include flame-retardant fibers modified by adding flame retardants and cross-linking agents, antibacterial fibers prepared by mixing quaternary ammonium salts, copper and silver antibacterial powders, and cool fibers made of jade, pearls and fiber composites. In the prior art, when lyocell fiber is produced, a crosslinking agent solution prepared by a crosslinking agent preparing device and filtered through a filter is mixed with cellulose in a pulp mixer. After the mixing is completed, the pulp mixer outputs pulp containing the crosslinking agent, and then the pulp is transported to an evaporator to prepare a glue solution, which is dissolved under stirring and vacuum conditions to prepare the glue solution, and then the crosslinked lyocell fiber is obtained after spinning. However, the crosslinking agent solution needs to be filtered, and the existing filter is extremely inconvenient to clean, which wastes a lot of manpower and material resources to clean the filter, thereby reducing production efficiency.
