Technical Field

The invention belongs to the technical field of wickerwork, and particularly relates to a recycling method of waste Chinese wolfberry and willow bark.

Background

in recent years, production tools, articles of daily use, artworks and the like prepared from willows are more and more popular with people due to the strong folk culture smell, and willow processed products are woven and stably deformed after being subjected to hot pressing, but no matter what processing method is adopted, the wood and willow rattan peels are required to be removed during the preparation of the products, so that the surfaces of the products are smooth, the later-stage processing is easy, and the practicability and the decoration of the willow products are improved; however, most of the remained willow bark is discarded or used as fuel, which causes great resource waste and environmental pollution.

the salix integra is a kind of willow commonly used in wickerwork, the salix integra bark amount generated by the wickerwork every year is large, and a proper treatment mode is not provided at present. For the recycling of salix integra bark, patent document CN106958159A discloses a preparation method of modified salix integra bark fibers, which is to perform boiling, acid and alkali treatment on salix integra bark, then perform fiber beating, and then soak the obtained fibers in a treatment solution, so that the blending property and the dyeing property of salix integra bark fibers are improved, but the strength is still low, and the color fixing capability of the fibers cannot meet the satisfaction of people.
