Problems solved by technology

The existing bamboo softening treatment methods are mainly soaking in boiling water and simmering. This method is relatively simple, but there are problems such as too long treatment time, poor softening effect, and poor strength recovery after weaving. People use chemical softeners. Appropriately shorten the processing time, but have little effect on other problems
In addition, once the existing bamboo-based willow products are formed, it is difficult to soften the shape again and cannot be effectively recycled

Embodiment 1

[0027] A kind of softening treatment method of bamboo, comprises the steps:

[0028] (1) Bamboo pretreatment:

[0029] After removing the tips and leaves of the bamboo, the bamboo is cut and segmented according to the processing requirements, and finally rinsed with clean water for later use;

[0030] (2) High temperature and high pressure treatment:

[0031] Put the bamboo treated in step (1) into an airtight tank, preheat the airtight tank to 80°C at a heating rate of 6°C / min, and then inject high-temperature water vapor into it, and control the temperature of the water vapor to 104~ 105°C, at the same time raise the pressure in the airtight tank to 1.5MPa, heat-preserve and pressure-hold the bamboo for 40 minutes, then quickly cool down and release the pressure to normal temperature and pressure, and finally take out the bamboo for later use;

[0032] (3) Ultrasonic cleaning treatment:

[0033] Put the bamboo treated in step (2) into a nitric acid solution with a mass fr...

Abstract

The invention discloses a softening treatment method for bamboo and belongs to the technical field of wicker processing. The softening treatment method comprises the following steps of (1) bamboo pretreatment, (2) high temperature and high pressure treatment, (3) ultrasonic cleaning treatment, (4) softening treatment fluid preparation, (5) soaking treatment and (6) dry weaving treatment. The method mainly improves softness during bamboo weaving, increases the weaving yield, also can effectively realize recovery and promotion of bamboo rigidity, improves the usage quality of a weaved product and prolongs the service life of the weaved product. Besides, bamboo after being treated in this way can be subjected to high temperature softening treatment and then deserve secondary plastic weaving, the problem that existing wickerwork cannot be effectively reused is solved, and the method has good popularization and use value.

Description

technical field [0001] The invention belongs to the technical field of wicker processing, and in particular relates to a bamboo softening treatment method. Background technique [0002] Funan County, affiliated to Fuyang City, Anhui Province, is an early inland development area, located in the northwest of Anhui Province, on the north bank of the junction of the upper and middle reaches of the Huaihe River. Funan County is known as "Famous Specialty Products County" and "Natural Resource Bank". It is a major grain production county in the country, the hometown of willow weaving in China, and the only agricultural (forestry) circular economy demonstration pilot county in the country. Funan is the national willow weaving county. Township, willow products are sold abroad. The materials used in willow weaving are not only wicker, but bamboo and rattan are common raw materials in willow weaving. Due to the characteristics of bamboo, it usually needs to be softened before weaving...
