Definitions

• This invention relates to a fiber-lubricant composition (or spin finish for staple) suitable for use in high speed spinning. More specifically, it relates to a basic ingredient to be incorporated in a spin finish for staple and its object is to provide a fiber-lubricant composition which can increase the fiber to fiber friction and improve the interfiber cohesion between fibers while preventing the falling-out of fibers during the drawing process.
• Synthetic fibers such as polyester fibers, acrylic fibers and polyamide fibers are used in large quantities in the spinning instead of natural fibers such as wool and cotton.
• synthetic fibers there are various problems concerning lubricity, antistatic property, interfiber cohesion, etc. Particularly, the adaptability of the spinning process at a high speed has been a serious problem.
• the spinning process of synthetic staple fibers composed mainly of polyester or dry-spun acrylic fibers cannot be conducted smoothly as compared with the case of cotton, wool or acrylic fibers made by the wet spinning process, since melt-spun polyester fibers made by the melt spinning process and acrylic fibers made by the dry spinning process have a smooth surface configuration. There occur such troubles as winding up of fibers on cylinders at the carding process and winding up of fibers on the rolls at the drawing, roving and spinning processes. Occurrence of such operational troubles is greatly influenced by not only the surface state of the fibers but also the kind of surface treating agent used for the fibers.
• Surface treating agents or so-called textile lubricants are generally composed of a lubricating agent and an antistatic agent.
• the lubricating agent there are used animal oil, vegetable oil, mineral oil, fatty acid esters such as methyl oleate and butyl stearate, non-ionic surface active agents such as ethylene oxide adducts of fatty acids or fatty acid esters of higher or polyhydric alcohols, and anionic surface active agents such as alkyl sulfates, alkyl phosphates and fatty acid salts.

• the object of this invention is to provide a spinning finish or a basic ingredient therefor, which can increase the degree of interfiber cohesion of fibers while reducing the fiber to metal friction and the fiber to rubber friction, whereby falling off of fibers and winding up of fibers on the rolls can be prevented in the drawing process.
