Title:
高強度生体吸収性縫合糸用繊維の製造方法及び縫合糸用繊維
Document Type and Number:
Japanese Patent JP4405186
Kind Code:
B2
Abstract:
A PGA/PLA copolymer suture fiber having a fiber tenacity of between approximately 7.2 to 8.0 grams per denier and a fiber elongation between approximately 22% and 35% is produced by a process that utilizes extruder apparatus having at least one heated zone that is maintained at a temperature of from about 20 DEG C below the copolymer melting point to about 5 DEG C above the copolymer melting point, a metering pump and a heated block that are maintained at a temperature of no more than about 40 DEG C above the copolymer melting point, a spinneret that is maintained at a temperature of from about 40 DEG C to about 60 DEG C above the copolymer melting point, and an elongated heated sleeve extending between six and twenty inches from the spinneret that is maintained at a temperature of at least about 60 DEG C above the copolymer melting point.
