Abstract

The invention relates to a spinning finish for a degradable stent fiber for human bodies. The active ingredient of the spinning finish comprises the following components: 12-24 parts of lubricating cohesive agent (corn oil), 36-55 parts of emulsifier (sucrose fatty acid ester), 13-27 parts of penetrant (polyoxyethylene sorbitan monolaurate), 5-8 parts of antistatic agent (polyethylene glycol) and 3-6 parts of antimicrobial agent (chitosan). The spinning finish for a degradable stent fiber for human bodies has favorable antimicrobial effect, avoids the phenomena of molding and deterioration in the storage and use process, has the advantages of obviously enhanced stability, high safety and no toxicity, is degradable, and has favorable biocompatibility with tissues of human bodies.

Description

technical field [0001] The invention relates to an oil agent used in the spinning process of synthetic fibers, in particular to a spinning oil agent for degradable scaffold fibers used in the human body, which is a degradable oil agent used in the human body with good biocompatibility. Spinning finish for scaffold fibers. Background technique [0002] Synthetic fibers do not have the natural colloid and oil film that natural fibers have. They have poor hygroscopicity and are non-conductive. Therefore, static electricity is generated due to constant friction during the spinning process. Auxiliaries must be used to prevent or eliminate static electricity accumulation. The fiber is soft and smooth, so that it can pass through the subsequent process smoothly. This kind of additive is collectively called fiber spinning oil. Fiber spinning oil should have the following characteristics: smooth, antistatic, clustering or cohesion, etc.; good thermal stability, low volatility; no co...
