Problems solved by technology

[0002] Linden is the soft bark between the hard bark and the trunk of the linden tree. After peeling the bark of the linden tree in spring, measure a certain length after choosing the linden tree, saw it up and down circularly, and then pull a knife vertically up and down, the tree can be smoothly cut. After the skin is peeled off and dried in the sun, it can be torn into flax and then twisted into a rope. However, during the processing of bassine, it is very easy to cause the degradation of the hemicellulose in the bassine, reducing its toughness and fracture strength, making the weaving performance and The quality of use is reduced; therefore, inventing a treatment method that can effectively improve the weaving performance of linden and prolong its service life is of great significance to the development of linden processing technology.

Abstract

The invention belongs to the technical field of tilia bast fiber processing and particularly relates to a processing method for improving tilia bast fiber knitting property. The processing method comprises the following specific methodssteps: performing boiling, freezing and steam and treating fluid dipping treatment on tilia bast fiber and performing temperature-change drying, ultrasonic, variable pressure and constant-temperature drying treatment. In the step of performing boiling, freezing and steam and treating fluid dipping treatment on tilia bast fiber, degradation of hemicelluloses in the tilia bast fiber is effectively inhibited; as the hemicelluloses has an adhesion effect in cell walls, the bonding strength among the tilia bast fiber is enhanced, and the toughness and the breaking resistance of the tilia bast fiber are improved; furthermore, a the color and luster degree of the tilia bast fiber is effectively improved, and sun resistance of the tilia bast fiber is enhanced. In the step of performing temperature-change drying, ultrasonic, variable pressure and constant-temperature drying treatment, conduction resistance of moisture in the tilia bast fiber is reduced, permeability of the tilia bast fiber is improved, the combining capacity between components of the treating fluid and tilia bast fiber cellulose molecules is enhanced, hygroscopicity of the tilia bast fiber is reduced, and dimensional stability of the tilia bast fiber is improved; furthermore, breeding of mould and putrefying bacteria is effectively inhibited, service life of the tilia bast fiber is prolonged, and use quality of the tilia bast fiber is improved.
