Thermoplastic polyester spinning tube for ring spinning machines - is pref. made of polybutylene terephthalate to reduce wear and improve gliding property

摘要

A spinning tube (18) is for a spinning machine, a ring spinning machine in partic. on which drawn and twisted yarns are wound by means of spindles (10). The spinning tubes (18) are mounted on the spindles (10) and are made of thermoplastic polyester, pref. polybutylene terephthalate (PBTP). ADVANTAGE - The spinning tube is suited to spinning machines with speeds of over 20,000 U/min. as they have reduced wear rates and better gliding properties.
