Abstract: 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.

Abstract translation: 公开了一种用于生产包括交替预定长度的第一和第二纱线和纱线的拼接纱线的方法。将预定长度的第一纱线通过混合射流抽出。 第二纱线的引导部分进入混合射流并与第一纱线的尾部重叠。 使用加压流体，将第一和第二纱线的重叠部分混合，从而将第二纱线的前部部分接合到第一纱线的后部。 然后将第一纱线切断，并且将接合部分和第二纱线的预定长度拉过混合射流。 重复该循环，其中第二根纱线是当前拉伸的纱线，第一根纱线与之重合。第一条纱线优选地保持在混合射流中，如通过设置在喷嘴前方的夹具，而形成混合的接头 。 形成混合接头的加压流体的压力范围为六十（60）至一百（100）磅/平方英寸（413.4至689.4千帕），更优选在六十（60）至 八十（80）磅每平方英寸（413.4至551.2千帕）。 如此形成的每个接头必须能够承受至少6.8磅（3.1千克）的张力。 第一纱线和第二纱线的预定长度可以相等或不同。 优选地，第一和第二纱线被染色成不同颜色。
