Abstract

The invention provides a macro-scale biological nylon fiber containing active ingredients of coffee and a preparation method thereof, and belongs to the technical field of fiber materials. The preparation method includes the following steps: crushing coffee beans, extracting active ingredients with antibacterial and antiviral effects, such as chlorogenic acid, caffeine and trigonelline, loading the extracted active ingredients on porous nano-particles, and modifying; and finally, carrying out melt spinning on the modified porous nanoparticles containing the active ingredients of the coffee and chinlon 66 slices to obtain the macro-scale biological chinlon fiber containing the active ingredients of the coffee. According to the method, the compatibility between the active ingredients of an extract and polyamide fibers is good, the active ingredients of the extract can be stably distributed in the polyamide fibers, and the immobilization degree is good; in a preparation process, the active ingredients are protected by a porous nanoparticle molecular nest technology, so that the loss caused by a high-temperature process is reduced, and the modification effect is good; the prepared macro-scale biological chinlon fiber containing the active ingredients of the coffee has a good virus inhibition effect.

Description

technical field [0001] The invention belongs to the technical field of fiber materials, in particular to nylon large biological fibers containing coffee active ingredients and a preparation method thereof. Background technique [0002] Coffee (Coffea spp.) was planted in Arabia more than 2,500 years ago and has become popular all over the world as a drink, becoming the first of the world's three major beverage plants. Coffee beans have been included in many herbal books because of their magical effects. According to "Chinese Materia Medica", coffee properties: slightly bitter, astringent, flat; efficacy: refreshing, diuretic, stomach invigorating; indications: mental fatigue, loss of appetite; used as refreshing medicine, diuretic, and stomachic medicine. These effects of coffee are closely related to the activity of its chemical components. The main chemical components in coffee include chlorogenic acid, caffeine, trigonelline, etc., which are important physiologically ac...
