Description

Slub type core yarn and manufacturing apparatus thereof {Slub type core yarn and manufacturing device approximately}

The present invention relates to a core yarn having a slab form and an apparatus for manufacturing the same.

Slub Yarn is a yarn that makes the slub appear occasionally, and in the spinning process, if the feeding speed of roving is increased or decreased, the feeding speed of the yarn is increased to make a thick and thin part in the yarn to give a constant twist. The thin part receives more kinks, but the thick part receives less kinks, resulting in a partially thicker slab shape, which is used as a design thread. The method of manufacturing the slab yarn is an old technology and various kinds have been developed.

On the other hand, core yarns are made of ordinary fibers with effect yarns, which have excellent mechanical properties, so that the mechanical properties and effect of the yarns can be obtained simultaneously, and the decorative effect can be obtained. Various kinds of core yarns and methods for producing the same have been known, such as producing elastic yarns using low-stretch filaments such as high-stretch filaments or polyester as screenings.

However, no core yarn having a slub form is known to date so that the portion of the coated fiber corresponding to the effect yarn in the core yarn is in the form of a slug.

Because of its excellent decorative effect and tactile feel, the slab yarn has been widely used in the design of clothing and the like, but its mechanical properties have been limited. In particular, although there is a limitation in imparting elasticity, core yarns having a slub shape have different development processes and manufacturing apparatuses of slub yarns and core yarns manufacturing processes and apparatuses, and their operations are different from each other.

It is possible to obtain a core yarn having a slab form according to the design.

The front roller brake 15 and the clutches 16 connected thereto are controlled by the slab formation control device 17 so that rotation is interrupted. The slab formation control device 17 is a means for controlling the surface speed of the irradiation in accordance with the shape, size and spacings between the slabs to be formed, and mainly controls the surface speed of the irradiation. Manufacture. Thus, the slab formation control device 17 is a means for supplying irradiation at a predetermined speed, and may be a conventional punching tape or a microprocessor (or computer) in which a speed regulation profile is stored.

The slab formation control device 17 directly controls the rotational speed of a normal motor (not shown for simplicity of the drawing) or the front roller brake 15 connected to the motor and the clutch 16 connected thereto. It can be easily understood by those skilled in the art that the surface speed of the irradiation can be controlled by means of.

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

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

The raw materials were put into the cotton spinning process, and after the irradiation was made in the spinning process, the irradiation was used as an effect yarn by connecting to the irradiation winding roll (1) of the core yarn manufacturing apparatus having a slab form according to the present invention. On the other hand, 50 f of polyester filament yarn (low stretch yarn) was connected to the take-up winding roll 9 and used as a screening. The irradiation was supplied to the front rollers through the irradiation guide (2) through the irradiation guide (2), the back rollers, the middle rollers. In addition, the audit was supplied to the front rollers through the audit guide roll 9, the audit guide 10, the audit tension guide 11, the audit supply roller 12, and the audit departure prevention guide 13. At this time, in order to give tension to the screening, the front roller surface speed and the surface speed ratio of the screening supply roller 12 were adjusted to 1:06. Slub-shaped roving fleece passed through the front roller and the screen was discharged at 40/1 applying a twist of 29 tpi (twist per inch). At this time, the rotation speed of the spindle was adjusted to 11,000. In order to form the slab, the surface speed of the front roller is changed intermittently, and the front roller brake is controlled by the slab formation control device 17 by adjusting the slub portion 200cm thicker than the top portion to 5cm and the top portion 70cm. 15) and clutch 16 are controlled. The core yarn having the resultant slab form was obtained by being wound around the tube forming portion 14. The obtained core yarn having a slub form had normal diameters, diameters and arcs at a warp density of 140T / inch and weft density of 76T / inch, and then weaved to perform normal processing of the polyester blend fabric. The processed fabrics were uniformly distributed in the shape of the slab, and were properly distributed and distributed, and the coverage was also excellent, and the excellent feel of cotton was detected, and the productivity of weaving and dyeing processing was also good.
