Spinning yarn bonding device

Abstract

The invention relates to a spinning yarn bonding device which comprises a hot bonding roller with a heater, a plurality of yarn feeding sets surrounding the circumferential direction of the hot bonding roller, and a press roll. The press roll and the hot bonding roller are pressed together in the mode of being tangent to the periphery of the hot bonding roller. Each yarn feeding set comprises a main unwinding roll, at least one secondary unwinding roll and a false twister, yarn provided by the yarn feeding set is wound around the periphery of the hot bonding roller to form overlapped doubled yarn, and the doubled yarn leaves the hot bonding roller after passing through the tangent position of the press roll and the hot bonding roller. The main unwinding rolls are used for unwinding poor-flexibility fiber yarn, the secondary unwinding rolls are used for unwinding good-hot-viscidity chemical fiber yarn, such as dacron, and the good-hot-viscidity chemical fiber yarn is heated to be fused and can serve as a crosslinking agent, so that a layer of crosslinking agent adheres to the surface of the poor-flexibility fiber yarn and the portions between the fibers forming the yarn, and a crosslinking function is provided for the subsequent process that the yarn forms the doubled yarn through hot bonding.

Description

technical field [0001] The invention relates to a yarn thermal bonding device, in particular to a textile yarn bonding device. Background technique [0002] Existing yarns are often plyed by twisting, but for some yarns composed of fibers with poor flexibility, if they are twisted, a large number of fibers constituting the yarn may be broken, resulting in the yarn as a whole The row strength is not high enough, so it is not suitable for plying by twisting. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art and provides a textile yarn bonding device. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a textile yarn bonding device, which is characterized in that it includes: a thermal bonding roller provided with a heater, several A yarn feeding group, and pressure rollers pressed together tangential to the outer circumference of the thermal bonding roller, the yarn feeding gr...
