Problems solved by technology

[0005] At present, there are few research reports on the reuse of kudzu root waste residue. If the kudzu root fiber can be extracted from the kudzu root waste residue and used in the textile field, it will not only be able to develop pure green and pollution-free natural fibers, but also benefit the ecological environment and achieve waste utilization. save resources

Embodiment 1

[0053] According to the above process:

[0054] (1) Sorting, get Pueraria radiata waste residue 10g, sort, remove unseparated massive Pueraria lobata piece and crushed sand and stones and other sundries.

[0055] (2) Washing with water, fully washing to remove fine sand, soil, residual arrowroot powder that has not been fully extracted, and single fibers with short lengths.

[0056] (3) dry, dry naturally for 24 hours.

[0057] (4) fluffing, with the method of mechanical fluffing, removes the small impurity that adheres to the kudzu root fiber and the single short fiber below 5mm.

Abstract

The invention discloses a method for preparing pueraria fibre from pueraria waste residue, belonging to the field of textile engineering. The method comprises the following steps: (1) separation, (2) water rinse, (3) drying, (4) fluffing, (5) microwave treatment, (6) water rinse,(7) acid rinse, (8) water rinse, (9) first soda boiling, (10) water rinsing, (11) second soda boiling, (12) fibre breaking, (13) bleaching, (14)dehydration, (15) oil Providing (16) dehydration (17) fluffing and (18) drying. The invention adopts the combined technology of microwave-chemical degumming, achieving a shorter total degumming cycle than the total degumming cycle achieved by employing the method only by chemical degumming techniques through strong acid and strong alkali. The fabrication method is simple and less labor-consuming. The invention can lower the production cost and is beneficial to the industrialized production. The method can make use of the pueraria waste residue for a better end, contributes a lot to environment preservation and energy saving. In addition, the pueraria fibre obtained by the method can meet demand of the people on environment-friendly purely natural fibres.

Description

technical field [0001] The invention relates to a method for preparing fibers for spinning from kudzu root waste residue, which belongs to the field of textile engineering. Background technique [0002] Pueraria vine, also known as Pueraria puerariae and Pueraria vine, belongs to the genus Pueraria genus of leguminous plants. Pueraria lobata is a commonly used traditional Chinese medicine. It has the effects of relieving muscle and reducing fever, promoting body fluid, promoting rash, promoting yang and relieving diarrhea. disease. Pueraria lobata is rich in starch, isoflavones, and more than ten kinds of trace elements necessary for the human body, such as calcium, selenium, iron, copper, phosphorus, and potassium. It is an emerging green health-care longevity food and a product in high demand for export. Puerariae is widely distributed in my country, except Xinjiang and Tibet, it is distributed in most provinces and autonomous regions of the country. Puerariae is a medic...
