2075992 9113194 PCTABS00007 Nylon carpet or textile yarn may be produced at an increased rate of throughput/spinneret hole by incorporating into nylon 6.6 polymer a secondary component which improves processability and lustre by suppressing spherulitic growth. The secondary component may be a co-monomer (e.g. hexamethylene diamine/isophthalic acid) which is incorporated during polymerisation to form a random co-polymer, a polymer (e.g. nylon 6) which is molecularly dispersed in the nylon 6.6 polymer without significant copolymerisation occurring or a metal salt (e.g. lithium choride).
