Abstract

Pluoštas iš polikaprolaktamo santykinio klampumo RV nuo 2,0 iki 3,0(klampumas matuojamas ištirpinus 1 g. pluošto 100 ml 96 svorio % sieros rūgštyje) gaunamas@(a) Ekstruduojant daugiausiai iš polikaprolaktamo sudarytą lydalą per filjerą, taip suformuojant polikaprolaktamo gijas;@(b) Atvėsinant taip pagamintas gijas ir@(c) Atvėsintus filamentus nuimant mažiausiai [3600+1250,(3,0-RV)] m/min greičiu,@kadanaudotas verpimui polikaprolaktamas sintetinamas dalyvaujant mažiausiai vienai dikarboninei rūgščiai, parinktai iš šių organinių rūgščių grupių:@-C4-C10-alkandikarboninių rūgščių;@-C5-C8-cikloalkandikarboninių rūgščių;@-Benzol- ir naftalindikarboninių rūgščių, galinčių turėti iki 2 sulfo grupių, kurių molėkulėse karboksilinės grupės nėra gretimos;@-N-C1-C6-alki-N,N-di(C4-C10-alkankarboninių rūgščių) aminų;@-1,4-piperazin-di(C1-C10-alkankarboninių rūgščių), o taip pat šių siūlų panaudojimas pluoštinių medžiagų ir tekstilinių gaminių gamyboje.Polycaprolactam relative viscosity RV from 2.0 to 3.0 (viscosity measured by dissolving 1 g of fiber in 100 ml of 96% sulfuric acid) is obtained by @ (a) Extraction of a polycaprolactam-based melt mainly through the filament to form polycaprolactam strands; (b) Cooling of the Threads Made in this way and @ (c) At least [3600 + 1250, (3.0-RV)] m / min of cooled filaments used for spinning, polycaprolactam is synthesized in the presence of at least one dicarbonic acid selected from these organic acids @ - C4-C10-alkanecarboxylic acids; @ - C5-C8-cycloalkanecarboxylic acids; @ - Benzene- and naphthalic-carbonic acids capable of containing up to 2 sulpho groups in which the carboxylic groups are not adjacent to the @ @ - N-C1-C6- Al-N, N-di (C4-C10-alkanoic acids) amines; @ - 1,4-piperazine di (C1-C10-alkanoic acids), as well as the use of these yarns in fibrous materials and textiles products.
