Abstract

The invention relates to the field of chemical fibers, in particular to a cellulous fiber, a preparation method thereof and equipment. The cellulose fiber mainly comprises cellulous, is prepared by the solidifying liquid co-current drawing and spinning technology, and meets the following conditions that the tension breakage strength of the fiber is higher than or equal to 2.0cN / dtex, the fineness of the fiber is equal to or smaller than 1.67dtex, the content of S elements in the fiber is smaller than or equal to 100ppm, the fibrillation index (F.I.) of the fiber is smaller than or equal to 2. In addition, the cellulose fiber is free of chemical compositions relevant to fibrillation treatment resistance. The invention further relates to the preparation method of the cellulous fiber and the equipment. The cellulose fiber is high in strength, low in fineness and free of fibrillation tendency, the preparation method is simple, and is easy to control and applicable to large-scale industrialized production, and the equipment is simple in structure, skillful in design and stable in condition.

Description

technical field

[0001] The invention relates to the field of chemical fibers, in particular to a fiber with cellulose as its main component and a manufacturing method and equipment thereof. Background technique

[0002] The structural unit in the cellulose molecular chain is glucose, and Oita contains a large number of hydroxyl, ether and glycoside bonds. The molecular chain structure of cellulose determines the inherent hygroscopicity, dyeability, wearing comfort and biodegradability of cellulose fibers. Natural cellulose fibers include cotton, hemp fibers, etc., mainly cotton fibers. Regenerated cellulose fibers include viscose fiber, cupro ammonia fiber, acetate fiber (cellulose acetate derivative fiber), etc., mainly viscose fiber, which has a development history of more than one hundred years.

[0003] Since the middle of the last century, with the rapid development of the petroleum industry, synthetic fibers have occupied the main market of fiber materials due to the...
