    • An agent and method for treating biodegradable synthetic yarns fabricated from a polymer comprising lactic acid as a main component, which enable improved lubricity, cohesion, etc. to be so imparted to the biodegradable synthetic yarns that the yarns can be prevented from fuzzing and breaking at every step from spinning to down-stream step, especially at a false twisting step and improved in terms of bulkiness, providing yarns having improved mechanical properties in a stable manner. The agent of the invention comprises 0.1 to 30 weight % of a specific functional agent, and a lubricant and a surfactant in the total amount of 70 weight % or greater, and has a friction coefficient in the range of 0.04 to 0.35.
    • 一种用于处理由包含乳酸作为主要成分的聚合物制成的可生物降解的合成纱线的试剂和方法,其能够改善润滑性,内聚力等,以使得可生物降解的合成纱线能够防止纱线发生模糊和断裂 从旋转到下游步骤的每一步骤,特别是在假捻步骤中并且在蓬松度方面得到改进,以稳定的方式提供具有改进的机械性能的纱线。 本发明的试剂含有0.1〜30重量%的特定官能剂,总量为70重量%以上的润滑剂和表面活性剂,摩擦系数在0.04〜0.35的范围内。

    • This invention provides a method for filling a hollow portion of a hollow fiber with a gel without requiring special equipment such as pressure resistant facilities and enabling an industrial mass production, which comprises immersing said hollow fiber on the surface of which pores are diffusely distributed to communicate to said hollow portion in a gelable liquid, leaving said hollow fiber at room temperature so that said gelable liquid may be absorbed through said pores into the hollow portion, and finally causing thus absorbed gelable liquid gelled.
