Spliced yarn and method for forming the same
摘要:
A method for producing a spliced yarn comprising alternating predetermined lengths of a first and a second yarn and to the yarn are disclosed. A predetermined length of a first yarn is drawn through an intermingling jet. A leading portion of a second yarn is forwarding into the intermingling jet and into overlapping relationship with a trailing portion of the first yarn. Using a pressurized fluid the overlapped portions of the first and second yarns are intermingled, thereby to splice the leading portion of second yarn to the trailing portion of the first yarn. The first yarn is then severed, and the spliced portion and a predetermined length of the second yarn are drawn through the intermingling jet. The cycle is repeated with the second yarn being the currently drawn yarn and the first yarn being forwarded into overlapping relationship therewith. Preferably the yarns are held in the intermingling jet, as by a clamp disposed forwardly of the jet, while the intermingled splice is formed. The pressurized fluid forming the intermingled splice has a pressure in the range from sixty (60) to one hundred (100) pounds per square inch (413.4 to 689.4 Kilopascals), and more preferably, a pressure in the range from sixty (60) to eighty (80) pounds per square inch (413.4 to 551.2 Kilopascals). Each splice so formed must be able to withstand a tension force of at least 6.8 pounds (3.1 kilograms). The predetermined lengths of the first and second yarn may be equal or different. Preferably the first and second yarns are solution dyed to be differently colored.
