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.
