Description

technical field [0001] The invention relates to the field of nylon fibers, in particular to olive-containing nylon 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 g...

Problems solved by technology

The applicant found through research that in the process of preparing nylon fibers by the above-mentioned process, due to the characteristic that nano-silica particles tend to agglomerate, when used as a carrier loaded with functional components, their distribution inside the fiber is not good. The modification effect is unsatisfactory, and the characteristics of the functional components cannot fully exert the modification effect on the fiber

[0009] Furthermore, the applicant found in the process of using olive as a plant modification material to modify nylon 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.

And when the described active ingredient is loaded on the nano-silica particles, although the loading effect is better, its processing stability is not ideal, and the properties of different batches of nylon fiber products are inconsistent, which affects the large-scale production of functional nylon fiber products. , standardized production
