Self-crimpable nylon 66 carpet yarn

A melt-spinning process for producing self-crimping, nylon 66 carpet yarn at spinning speeds of, for example 4000 meters per minute is provided. The process utilizes polymer having a relative viscosity (RV) of at least 50 and containing a sufficient amount of a chain branching agent to prevent broke...

Zusammenfassung:	A melt-spinning process for producing self-crimping, nylon 66 carpet yarn at spinning speeds of, for example 4000 meters per minute is provided. The process utilizes polymer having a relative viscosity (RV) of at least 50 and containing a sufficient amount of a chain branching agent to prevent broken filaments and to provide yarn having good luster.
