Spinning stoste of cellulose derivative and its preparation and use

Abstract

The spinning stoste is prepared using CAB, CAP, HEC and HPC as raw material, acetic acid and formic acid as solvent, adding surfactant additive through the processes of fully stirring, standing by and de-foaming. The said stoste is used for electrostatic spinning to make super-thin fiber with diameter of 200-1000nm which has not only strong adsorb-ability, filtration-ability but also good biological compatibility and biological degradability and excellent ultraviolet-resisting and cold-resisting characteristics. Advantages: released nozzle blocked situation while conducting electrostatic spinning, reduced knob generation, uniform diameter of the super-thin fiber and increased production yield.

Description

technical field

[0001] The invention relates to a spinning stock solution of cellulose derivatives and its preparation and application, in particular to a spinning stock solution of cellulose ethers and esters and its preparation and application, and belongs to the technical field of spinning stock solution preparation and application. Background technique

[0002] Cellulose ethers and esters are natural polymer derivatives with good biocompatibility and biodegradability, as well as excellent properties such as UV resistance, cold resistance, flexibility, transparency and electrical insulation. Therefore, such raw materials Mainly used in coatings, leather brighteners and other industrial additives. At present, cellulose derivatives are used for spinning, especially for the preparation of ultrafine fibers by electrospinning. Except for the reports of using cellulose acetate, sodium carboxymethylcellulose and cyanocellulose as raw materials, other C...
