Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As schematically shown in FIG. 2, the fused welded twisted yarn for morphs according to the present invention is a state in which two or more yarns 12 are fused together with a heat fused yarn 13 having a low melting point and twisted. In the yarn 12 is characterized in that it is made by fusing the thermal fusion yarn (13).

The yarn 12 is not limited in kind, and single yarn or two or more ply yarns may be used. Natural yarns or synthetic fibers may be used as the yarn 12, and in particular, in the case of synthetic fibers, the conjugated yarn 11 obtained having a higher melting point than the heat-sealed yarn 13 used in the present invention. It is preferable for morphological stability and the like. Particularly, natural fibers such as cotton having excellent durability and hygroscopicity, such as mop, can be preferably used, and more preferably cotton fibers having a cotton number of about 0.5 to about 10 can be used.

All. It will be readily understood by those skilled in the art that the yarn 12 may be selected and used appropriate fibers depending on the use of the twisted yarn 11 obtained. 2 schematically illustrates a state using single yarn as yarn 12 in manufacturing the twisted yarn 11 according to the present invention, and FIG. 3 schematically illustrates a state of using yarn as yarn 12.

It will be understood by those skilled in the art that the yarns of the yarns 12 may be yarnd by conventional yarns commercially available in the art.

The fused yarns of the yarns 12 are fused together with a thermal fusion yarn 13 capable of fusion of the yarns 12 with each other.

It will be appreciated by those skilled in the art that the yarns 12 that have been plyed can also be twisted by conventional yarns commercially available in the art to form twists. Particularly preferably, the morphology for morph is twisted at 3 to 8 TPI (Twist per inch).

The obtained twisted yarn 11 is fused to each other by the yarns 12 constituting the twisted yarn 11 by thermoplasticity of the heat-sealed yarn 13 by heating. The twisted yarn 11 may include a thermal fusion yarn 13 so as to have a total denier of 6,000 to 8,000 D (denier). However, the limitation of these values is based on the case where the twisted yarn according to the present invention is used for the mop as described above, and the total denier of the twisted yarn or the material of the yarn 12 is obtained. It can be understood by those skilled in the art that it can be appropriately selected depending on the intended use.

Therefore, the fused plywood yarn 11 according to the present invention thus obtained is fused by heat fusion yarn 13 between the yarns 12 constituting the plywood twisted yarn 11 that is twisted and twisted to form twist. This will be prevented.

In addition, according to the present invention, a method of manufacturing a fused spliced twisted yarn for morphing includes heat-bonding yarn 13 having a low melting point thermoplastic of two or more yarns 12 selected from single yarn or two or more stranded plywood. A step of envoying together with the envoy; A twisting step of forming a twist on the yarn 12; It characterized in that it comprises a; fusion step of fusion to heat-bonded yarn 13 by heating the twisted yarn 12 is formed.

It can be easily understood by those skilled in the art that the step of weaving the yarn 12 is carried out by a common weaving machine, and it can be easily understood by those skilled in the art that the burning step can also be accomplished by a common combustor. It can be understood.

In the present invention, the plywood yarn is twisted in the plywood step, the twisted yarn is formed in the twisting step in the plywood step in the plywood step together with the yarns 12 in the heat fusion yarn 13 is fused to heat the twisted plywood yarn is formed therein It is characterized in that the yarns 12 are fused to each other by heating the included thermal fusion yarn 13.

The heat-sealed yarn 13 is formed of a low melting thermoplastic resin melted at a low temperature of 80 to 125 ℃ in the form of fibers compared to the conventionally used chemical fibers such as nylon and cotton yarn melt at 220 to 260 ℃ By heating, at a low temperature as a whole or at least partially melted to have a thermoplastic and heat sealability, and solidified as it is cooled again to serve to fuse and fix the yarns 12 to each other. The heat-sealed yarn 13 is also known to those skilled in the art to be commercially available and used, and examples thereof include polyethylene fibers or polyamide fibers having a low melting point. Particularly, in the bonding method, conventionally, the twisted yarn cord is bonded by a method of wet heat treatment at a relatively high melting point, which may result in nonuniform results, but according to the present invention, it may be performed by heating by electric heat. By using the heating drum of the drum temperature and rotation speed, such as to control the uniformity and easy heat treatment can be improved productivity.

Hereinafter, preferred embodiments and comparative examples of the present invention will be described.

The following examples are intended to illustrate the invention and should not be understood as limiting the scope of the invention.

Example 1

When joining two strands of relatively thick cotton yarn with a cotton number of 1.5, the two strands of 75D heat-fused yarns are positioned between the yarns of Z, and S-spun at 7TPI, and then the obtained twisted yarn is about 120 ° C. Heating yielded a fused spliced twisted yarn for morphs according to the invention that can be used for mops.

The obtained twisted yarn was visually confirmed that the yarn was not loosened at the cut surface even by the intermediate cutting.

Example 2

When joining two strands of 3,240D twisted yarns by combining 120D and 27 split microfibers in a conventional manner, the two strands of 75D heat-bonded yarns are positioned between the yarns, and the Z twisted yarn is 5.5TPI. The obtained twisted yarn was then heated to about 150 ° C. to obtain a fused bonded twisted yarn for morphs according to the present invention, which can be used for mops. The heat-bonded yarn in the obtained twisted yarn is almost melted at the center of the twisted yarn, and each of the split microfibers constituting the yarn is in a spiral state while protruding from and passing through the surface. It was confirmed that it consists of a structure to maintain a state in which they are sequentially bonded.

The obtained twisted yarn was visually confirmed that the yarn was not loosened at the cut surface even by the intermediate cutting.

Therefore, according to the present invention, the loosening phenomenon between the yarns 12 does not occur in the cut surface, and the yarns 12 are directly fused to each other to maintain the coalescing state and to prevent the separation and cutting of the yarns 12. Durability is improved, and there is an effect of maintaining a beautiful appearance.
