Problems solved by technology

The applicant has found through research that in the current process of preparing ES fibers using the above-mentioned process, due to the characteristic that nano-silica porous particles tend to agglomerate, when they are used as a carrier loaded with functional components, their distribution inside the ES fiber skin layer Poor performance, unsatisfactory modification effect, and functional ingredients cannot fully exert the modification effect on the fiber
[0010] Furthermore, the applicant found in the research process of using olive as a plant modification material to modify ES fiber that when the active ingredients extracted from olives were loaded on a common carrier, the loading effect was not ideal and the process requirements could not be met.
When the active ingredient is loaded on the nano-silica porous particles, although the loading effect is better, the olive active ingredient is easily affected by the process and lost during the fiber processing and molding process, and the processing stability is not ideal.

Abstract

The invention provides ES fiber containing olive and a preparation method of the ES fiber. The preparation method comprises the following steps: preparing an olive extracting solution, preparing molecular nest particles, preparing the molecular nest particles containing an olive extract, preparing a skin layer material, preparing a core layer material, spinning and post-treating. The ES fiber containing the olive has the beneficial effects that the antibacterial rate of the ES fiber containing the olive to staphylococcus aureus is greater than or equal to 99.3%, the antibacterial rate of the ES fiber containing the olive to escherichia coli is greater than or equal to 96.8%, the antibacterial rate of the ES fiber containing the olive to candida albicans is greater than or equal to 95.2%; after 1.2*10<-2> w / in2 ultraviolet irradiation for 50 hours, the physical properties of the fiber can still be maintained at 96.1% or above; and the modulus of the fiber is 163-170 N / tex.

Description

technical field [0001] The invention relates to the field of ES fibers, in particular to olive-containing ES fibers and a preparation method thereof. Background technique [0002] Olive, arbor plant of the family Olivaceae. It can reach a height of 35 meters and a diameter at breast height of 150 centimeters. 3-6 pairs of leaflets, papery to leathery, 12-16 pairs of lateral veins, infructescence 1.5-15 cm long, with 1-6 fruits. Oval to spindle-shaped, yellow-green when mature, thick exocarp, hard core, pointed at both ends, and roughened nuclear surface. The flowering period is from April to May, and the fruit matures from October to December. Olives are native to southern China and are cultivated in Fujian, China, Taiwan, Guangdong, Guangxi, Yunnan, Japan (Nagasaki, Okinawa) and the Malay Peninsula. Wild olives are found in valleys and hillside miscellaneous forests below 1,300 meters above sea level. , or cultivated in gardens and villages. [0003] Olive is a good wi...
