Spinneret assembly for use in production of multi- ingredient multi-core composite filaments

Abstract From the Canadian patent

This invention provides an improvement in a spinneret assembly. The assembly comprises superposed rigid first, second, third and fourth plate members. The first and second plate members partition off a first and second polymer chamber respectively, from a second and third polymer chamber respec-, tively. The third plate member partitions off the third polymer chamber from one or more funnel-shaped fourth polymer chambers bored in the fourth plate member. The third plate member has a plurality of holes which are exposed to each fourth polymer chamber. The fourth plate member has at the lowermost ends of each fourth polymer chamber an orifice. The third plate member further has bored therein …
