Improved flame retardant polytrimethylene terephthalate compositions are provided by including a certain phosphorous compound as a flame retardant additive.
摘要:
This invention relates to poly(trimethylene terephthalate)/poly(alpha-hydroxy acid) biconstituent filaments, methods for making the same and end uses thereof.
摘要:
In a first aspect the invention is a solid core fibrillation-resistant, synthetic polymeric filament having three substantially equal length convex sides. The sides through substantially rounded tips centered by a distance “a” from the axis of the filament. Each rounded tip has a radius substantially equal to a length “b”. Each tip lies on a circumscribed circle having a radius substantially equal to a length (a+b) and the midpoint of each side lies on an inscribed circle having a radius substantially equal to a length “c”. The filament has a denier-per-filament in the range 10
