Drawings
FIG. 1 is a schematic diagram of a first embodiment of the present utility model;
Fig. 2 is a schematic structural diagram of the second embodiment of the present utility model.
In the figure: 1. a main line; 2. auxiliary lines; 21. a winding part; 211. a positive twisting part; 212. a reverse twisting part; 22. and a float line part.
Detailed Description
In the following description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the device or element being referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model, and it is obvious that the described embodiments are only some embodiments of the present utility model, not all embodiments.
The elastic polyester yarn comprises a main yarn 1 and two bundles of auxiliary yarns 2, as shown in fig. 1 and 2, wherein the main yarn 1 is formed by twisting a plurality of strands of polyester hollow fibers by a twisting machine, the polyester hollow fibers have good elasticity and durability, the auxiliary yarns 2 are formed by twisting a plurality of strands of spandex fibers by a twisting machine, the spandex fibers have good elasticity, the bundled main yarn 1 and the two bundles of auxiliary yarns 2 are arranged on the twisting machine, the auxiliary yarns 2 are wound on the main yarn 1 in a mode of alternately applying twisting and false twisting, a plurality of winding parts 21 which are arranged at intervals are formed by winding the auxiliary yarns 2 around the main yarn 1, the adjacent winding parts 21 of any bundles of auxiliary yarns 2 are connected by a floating yarn part 22, and the floating yarn part 22 is formed by false twisting.
As shown in fig. 1, specifically, the winding portion 21 includes a plurality of positive twisting portions 211 and negative twisting portions 212 alternately arranged along the axial direction of the main wire 1, and any floating wire portion 22 connects adjacent positive twisting portions 211 and adjacent negative twisting portions 212, wherein the twist of the floating wire portion 22 is lower than that of the winding portion 21, so that the axial line of the floating wire portion 22 is arranged in a C-shaped structure, and the C-shaped structures of the adjacent floating wire portions 22 on each auxiliary wire 2 are opposite, so that when any floating wire portion 22 of any auxiliary wire 2 is connected to two ends of the winding portion 21 and is loose from the main wire 1, the floating wire portion 22 of another auxiliary wire 2 is limited.
With this configuration, any float portion 22 of any one of the auxiliary yarns 2 can move in the direction of loose twisting until one end thereof abuts against a float portion 22 of another auxiliary yarn 2 that moves in the same direction of loose twisting, and when the two float portions 22 abut against each other, the loose twisting cannot be continued, and finally the float portions 22 of the two auxiliary yarns 2 are bonded to each other by self-releasing twisting of the auxiliary yarns 2.
A plurality of floating thread parts 22 which can float on the surface of the auxiliary thread 2 are arranged on the peripheral side of the polyester yarn, especially the floating thread parts 22 of two bundles of auxiliary threads 2 are jointed in a two-to-two mode, and the elastic recovery effect of the C-shaped structure of the floating thread parts 22 when being pressed is utilized, so that when the peripheral side of the fabric made of the polyester yarn is stressed, articles contacting the fabric can be elastically supported better.
As shown in fig. 1 and 2, in order to secure the positions where the forward twisting portion 211 and the reverse twisting portion 212, which are connected to the float portion 22 at the time of untwisting, are wound around the main yarn 1, the twist of the forward twisting portion 211 is equal to the twist of the reverse twisting portion 212.
