Abstract
The invention relates to threads, fibers or films comprising polyvinylidene fluoride, with good dye affinity for plastosoluble and cationic dyestuffs. More particularly, the invention relates to threads, fibers or films formed of a mixture of vinylidene fluoride homopolymer and of a copolymer containing at least 60% by weight of methyl methacrylate units and 5 to 40% by weight of units of at least one acid ethylenic comonomer, copolymerizable with methyl methacrylate. The threads and fibers in accordance with the invention can be used in particular in the field of textiles.
