STRUCTURE, BASIC PROPERTIES AND PROSPECTS OF APPLICATION OF COMPOSITE YARNS BASED ON POLYPROPYLENE
The problems of obtaining filled textile yarns from the melt are analyzed. The necessity of using nanosized fillers in a stabilized form is shown. The properties of composites based on polypropylene yarns with different fillers have been investigated. A fundamentally new method of producing composite yarns with properties similar to those of fluoroplastic filaments is described. The mechanism of formation of a fluoroplastic coating on polypropylene yarns is analyzed. The morphology and characteristics of the resulting composite yarns were evaluated.
