Abstract

The invention relates to an air knot type yarn knotting method for knotting a first yarn and a second yarn. The air knot type yarn knotting method comprises the following steps: one section of the first yarn is measured from the head end of the first yarn, and one section of the second yarn is measured from the tail end of the second yarn; an air blowing knotting machine is selected according to densities of the first yarn and the second yarn, and the air pressure of the air blowing knotting machine is adjusted; the first yarn penetrates through a first clamping port and a fourth clamping portin sequence, and the second yarn penetrates through the second clamping port and a third clamping port in sequence; or the first yarn penetrates through the second clamping port and the third clamping port in sequence, and the second yarn penetrates through the first clamping port and the fourth clamping port in sequence; the first yarn and the second yarn are knotted through the air blowing knotting machine after intersection; and the knotted section of the second yarn and the knotted section of the first yarn are blown to the knotting side through an air blowing outlet to form knotted yarns. The knotting method can be applied to enable the yarns to smoothly penetrate through yarn guide holes, and facilitates industrial application.

Description

technical field [0001] The invention relates to an air-knot yarn knotting method, which is suitable for the connection between yarns, especially for the connection between glass fiber plied untwisted roving yarn clusters. Background technique [0002] At present, the glass fiber plied rovings packaged in pallets are packaged independently and without connection between each yarn cluster. During use, after the previous yarn roll is used up, it needs to be shut down to connect the next yarn roll to continue production, which greatly affects the use efficiency of glass fiber yarn and cannot meet the needs of automated high-efficiency production. Connecting two yarn clusters end to end is suitable for continuous production. However, due to the characteristics of glass fiber yarns, knotting in ordinary ways will cause large knots. In the later production process, the yarn will pass through the guide. The yarn hole is not smooth, which affects the use efficiency. At the same tim...
