BUNDET FIBERKNIPPE, FOERFARANDE FOER FRAMSTAELLNING AV DETTA OCH DAERAV ERHAOLLNA TEXTILYTSTRUKTURER

摘要

There is described a yarn bundle made of at least one twisted multifilament yarn comprising a first synthetic polymer, for example comprising polyethylene terephthalate, having a breaking strength of at least 42 cN/tex, whose individual filaments have become bonded together over essentially the entire thread cross-section by the melting on means of a second thermoplastic synthetic polymer, whose melting point is at least 10 DEG C below the melting or decomposition point of the first synthetic polymer, for example polybutadiene terephthalate. The yarn bundles are distinguished by a high strength, a good flexural stiffness and good resistance to hydrolysis and can be used in particular for manufacturing textile sheet materials for use in hot, moist environments, in particular as wire cloths for paper machines.
