Embodiment Construction

[0024] The invention provides a technical solution: cotton biofiber containing coffee active ingredients and a preparation method thereof, comprising the following steps:

[0025] Step 1. Cleaning: Threshing and removing impurities from the harvested cotton to obtain clean and complete natural cotton fibers.

[0026] Step 2, dehydroxylation: In the state of heating, the original hydroxyl group is replaced by a group with stronger nucleophilicity than the hydroxyl group on the natural cotton cellulose fiber.

[0027] Step 3, deionized washing: washing with deionized water to clean the excess ions on the cellulose fibers.

[0028] Step 4, caffeine modification: Adding reagents containing caffeine active ingredients to further modify the cotton fiber obtained after the hydroxyl group has been changed, heating, pressurizing and stirring during the process.

[0029] Step five, physical cleaning: fully clean the modified cotton fiber with clear water.

[0030] Step 6. Physical dry...

Abstract

The invention provides a cotton large biological fiber containing coffee active ingredients and a preparation method thereof, and relates to the technical field of cotton fiber modification. The preparation method comprises the following steps that S1, blowing is carried out, specifically, threshing and impurity removal treatment is carried out on collected cotton to obtain clean and complete natural cotton fiber; S2, dehydroxylation is carried out, specifically, an original hydroxyl group is replaced with a group with stronger nucleophilicity than the hydroxyl group on the cellulose fiber of the natural cotton in a heating state; and S3, deionized water cleaning is carried out, specifically, cleaning is carried out with deionized water to clean redundant ions on the cellulose fiber. According to the cotton large biological fiber containing the coffee active ingredients and the preparation method thereof, hydroxyl bonds which are not stable enough on original cotton fibers can be replaced with more stable hydroxyl through the step of dehydroxylation, so that the anti-wrinkle performance of the whole cotton fibers is more perfect, the whole cotton fibers are not prone to wrinkling and shrinking, and a wearer feels more comfortable; and through modified reagents containing caffeine, the cotton fiber has the advantages of wear resistance, chlorine water resistance and the like, so that the service time of the whole cloth is prolonged.

Description

technical field [0001] The invention relates to the technical field of cotton fiber improvement, in particular to a cotton biofiber containing coffee active ingredients and a preparation method thereof. Background technique [0002] Cotton fiber, the fiber covered on the seeds of Malvaceae plants, also known as cotton, referred to as cotton, is an important raw material for the textile industry. Cotton is one of the most important crops in the world. Cotton fiber is mainly composed of cellulose fibers Composed of substances, it is a compound of natural polymer type, with large output and low production cost, which makes cotton products relatively cheap. Cotton fibers can be made into fabrics of various specifications, from light and transparent voile to thick canvas and thick velveteen , suitable for making all kinds of clothes, furniture cloth and industrial cloth, its main component is cellulose, cotton fiber products are hygroscopic, good air permeability, soft and warm, ...
