Abstract

The invention provides a cellulose fiber containing an aloe extract. The cellulose fiber is prepared by blending a spinning solution and the aloe extract. The invention further provides a preparation method of the cellulose fiber containing the aloe extract. The dry breaking strength of the prepared cellulose fiber is up to 2.08-2.76 cN / dtex, the wet breaking strength is up to 1.26-1.72 cN / dtex, the dry elongation at break is up to 18.3-25.2%, and the residual sulfur content is low; the over-length fiber rate and the double-length fiber rate are low, defects are few, and a dry-state breaking strength coefficient of variation (CV) is small. The aloe extract for the prepared cellulose fiber is long in slow-release period, and the slow-release period is up to 1.1-1.8 years. The prepared cellulose fiber has a good ultraviolet-proof performance and a good bacteriostatic effect and is resistant to washing. The knitted fabric made of the cellulose fiber has skin irritation resisting, anti-allergy and skin itching relieving functions.

Description

technical field [0001] The invention relates to a cellulose fiber containing aloe extract and a preparation method thereof, belonging to the field of fiber preparation. Background technique [0002] At present, one of the main sources of bulk fiber is underground non-renewable petrochemical resources such as petroleum and coal, and the other is renewable resources such as cotton, hemp, silk, and wool that are planted and farmed on land. Among them, synthetic fibers are derived from petrochemical resources and are non-renewable resources. With the continuous outbreak of the global energy crisis, the number of synthetic chemical fibers will hardly continue to grow. In recent years, the development of regenerated cellulose fibers has eased the pressure of insufficient production capacity of textile fibers. [0003] Ordinary regenerated cellulose fibers mostly use cotton linters and wood as raw materials. Limited by the performance of raw materials and production and processing...
