Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a lyocell fiber pulp crushing and swelling integrated machine. Background Art

[0002] Lyocell fiber, also known as "Tencel", is a cellulose fiber extracted from plant wood pulp and obtained through an organic solvent spinning process. Not only is the raw material natural, but the solvents used in the production process can be naturally degraded and absorbed by the environment. Therefore, it is known as the "green fiber of the 21st century."

[0003] For this reason, Lyocell fiber (Tencel) has always been a symbol of high quality and is widely used in high-end clothing brands. Lyocell fiber (Tencel) is a high-end fiber that combines the advantages of cotton, linen, silk and polyester. It has better moisture absorption than cotton, and has the breathability and perspiration-relieving properties of linen, the soft touch and flow of silk, and the strength of polyester.

[0004] Lyocell fiber is made by dissolving wood pulp cellulose in an organic solvent and then spinning the solution into fibers. The production process of Lyocell fiber mainly includes the following steps:

[0005] 1. Wood pulp preparation: Natural wood is chemically treated to make wood pulp.

[0006] 2. Cellulose dissolution: Put wood pulp cellulose into an organic solvent, heat and stir to completely dissolve the cellulose.

[0007] 3. Spinning into fibers: The solution is sprayed out through a spinneret to form fibers.

[0008] 4. Fiber solidification: The fibers are solidified by stretching, drying, heating and other treatments.

[0009] 5. Fiber processing: The fiber is processed by carding, dyeing and other processes to make finished products.

[0010] In the cellulose dissolving step, cellulose pulp, tertiary amine oxide (NMMO solvent), stabilizer, etc. need to be mixed by a mixer.

[0011] In the existing mixer, during the production process, part of the slurry is easy to stick to the inner wall of the machine, resulting in uneven mixing of the slurry. During discharge, the slurry is easy to stick, which also causes incomplete discharge. Utility Model Content
