Abstract

The invention belongs to the technical field of willow artwork, and particularly discloses a treatment method capable of improving the flexibility of osier. The treatment method specifically comprises the following steps: (1) ethanol solution soaking, constant-temperature fermentation and variable-temperature freezing treatment; and (2) microwave drying, vacuum soaking and variable-temperature drying treatment. According to the treatment method disclosed by the invention, pretreatment is carried out at first, and ethanol molecules are enabled to permeate into cellulose as protective mediums, so that the aggregation capacity among cellulose molecules is effectively improved, and the strength of the osier is effectively increased; and then the microwave drying and the vacuum soaking for a treatment liquid are carried out, the permeation time of the treatment liquid is effectively shortened, and the permeation efficiency is increased, so that the treatment liquid is capable of permeating into osier bark to soften and enable the bark to be closely bonded with an inner wood layer, bark peeling is avoided, high flexibility is achieved, the occurrence of a cracking phenomenon in a weaving process is effectively prevented, the weaving difficulty of the osier is lowered, the high-temperature-resistant and sun-screening capacity of the osier is improved, and the service life of the osier is effectively prolonged.
