Referring to fig. 1, the basic principle of the active yarn release scheme provided by the embodiment of the utility model is as follows: the yarn spool 20 rotates under the drive of the drive assembly 30 to release the yarn 90, namely paying out, and the textile machine 50 pulls the yarn 90 to move, namely take up, and the difference between the take up and paying out speeds mainly determines the tension of the yarn 90; the tension detecting device 40 is used for detecting the tension of the yarn 90; when the yarn tension is larger, the driving component 30 drives the yarn disc 20 to accelerate so as to reduce the difference between the take-up speed and the pay-off speed, thereby reducing the yarn tension; when the yarn tension is smaller, the driving component 30 drives the yarn disc 20 to decelerate so as to increase the difference between the take-up speed and the pay-off speed, thereby increasing the yarn tension; the yarn tension can be adjusted within a proper range to ensure the spinning quality.

Referring to fig. 2, two yarn reels 20 may be arranged on a single textile line, each yarn reel 20 being provided with a drive assembly 30 and a tension detecting device 40. In some examples, a textile article is co-woven from a plurality of yarns 90, whereby it is desirable to arrange a plurality of reels 20, a plurality of drive assemblies 30, and a plurality of tension sensing devices 40 to effect payout and tension control of the plurality of yarns 90.

A yarn releasing device provided by an embodiment of the present utility model will now be described. The yarn releasing device includes: the yarn feeder comprises a frame 10, a yarn tray 20, a driving assembly 30, a control assembly 32 and a touch screen 60.
