Hot melt size and yarn sized therewith and packages and fabrics of sized yarn

摘要

A non-aqueous,water-soluble, quick-setting sizing composition suitable for application in the molten state to textile yarns of both continuous- filament and staple types, and for later removal by aqueous means, comprising a combination of a film-forming thermoplastic polymer with a melt-miscible viscosity reducer and solification promoter, and yarns so sized. The polymer protects and consolidates the yarn, while its companion component promotes the even application and particularly the quick set-up of the molten size. Optionally, if desired, water-soluble lubricants may also be added to increase the lubricity and flexibility of the sized yarn.
