The present invention relates to a knitting method of knitting yarns that are stretched without the need for a rubber yarn by knitting the yarn wound on the bobbin and provide a yarn that is very soft to the touch.

Generally, a machine for weaving compressed air by spraying compressed air, such as an air jet and a water jet, that is, jetting water, that is, a yarn that is knitted only on looms, has poor touch and gloss. In order to retain elasticity, it is necessary to use a separate rubber yarn, so the production cost is high, the work is very complicated, and silk fabric with the characteristics of knitting and span (rubber yarn) was impossible.

Therefore, the present invention is devised to solve the above problems, and the first purpose is divided into the twist setting and the temperature / time setting of the setting process as the polyester (Polyester) process, the second object is the yarn as the knitting process It is divided into supply arrangement method, tension maintenance of yarn and density of knitted fabric, and the third purpose is preprocessing processing of printing material of printing cloth, and it is divided into shrinking processing of knitting fabric and tenter process of adjusting and drying crop width. The knitting process as described above is intended to provide a silk-like feel and elasticity and vivid printability.

In the knitting method of the present invention for achieving the above object, a configuration of a tension device belonging to a tension holding step, which is one of the knitting processes, will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1 or FIG. 2, there is shown a perspective view of the entire tension and the main portion of the tension device.

That is, in the upper plate 2 of the bobbin 1 is attached a plurality of spacing brushes 3 for maintaining the spacing in a digital manner when the twisted yarn is released from the bobbin 1, the bobbin 1 is The support frame 41 is fixed to the upper portion of the frame 40 placed on the ground and placed on the left side of the bobbin, and the tension body is arranged to be fixed to the support frame 41 in parallel with the bobbin. The elastic clamping portion 51 formed at the rear side is fastened, and a guide piece 52 for guiding the twist yarn is formed at the front of the tension main body, and the flange at the lower end on the guide piece guides the twist yarn to pass through the center of the guide piece. Guide holes 52a and 52b are formed, and a plurality of circular plates 54 and 54 'are fitted to the rolled bolt rod 53 penetrating the web of the guide piece to closely connect the yarns passing through the guide holes. Conical spring 55 is coalesced on one side Have an elastic force toward to the CS through the circular plate prevents kink, and will have one end of the spring adjustment nut 56 for adjusting the spring force of the spring is configured is screwed.

When the tension device which is a part of the whole process of the present invention configured as described above is fitted into the twisted yarn and then transferred to a conventional circular knitting machine, the operation and the embodiment of the following process will be described in detail.

A block diagram of the process according to the invention is shown as shown in FIG.

Example 1

The polyester process is to first set a twist setting (hereinafter abbreviated as TM setting) that twists a plurality of yarns to the left or the right side, and the test result is changed between TM1200 to TM1800 by 50 units, and is divided into pieces, pretreatment, etc. As a result of testing the process, it was found that the twisted yarn under TM1200 to TM1400 was not used to reduce shrinkage during pretreatment.

Therefore, in this process, TM setting is made so that the yarn containing 36DTY thread inside the diameter of 75D is twisted TM 1550 times per 1m during polyester yarn twisting process. To prevent this, the process of increasing the strength of the yarn by immersing the detergent-coated water in the yarn before the spinning is omitted.

Because white detergent powder is continuously generated during the knitting process, it melts in the oil lubricated in various mechanical knitting devices and degrades its performance. Also, the tensioning device of each part cannot be maintained uniformly due to the degradation of the mechanical knitting device. Tension defects occur in the width direction of the knitted fabric.

It was also a factor in shortening the life of knitting needles.

After that, the setting process is a process of using the bobbin thread wound after the yarn without being warped, and setting the temperature and time is important.

In particular, excessive setting is not easy to shrink in the pretreatment process after knitting, not only affects the printing after printing process, but also loses the elasticity characteristic of the fabric.

In addition, if the proper setting is not made, the yarns fed in the knitting process are twisted and the two layers of yarns are overlapped and thus the tension of the yarns cannot be maintained uniformly.

As a result, a defect such as a pull string occurs in the width direction of the knitted fabric after the knitting.

Therefore, the proper setting temperature at this time is 80 ° C and the time is 50min, which prevents double yarns from being overlapped by twisting the yarns fed in the next step of the knitting process, and at the same time maintains the yarn tension uniformly. A defect such as a pull string does not occur in the width direction of the knitted fabric.

Example 2

In the knitting process, first, as a method of arranging the yarns, the left and right yarns were arranged in a 1: 1 manner, and as a result, too many valleys appeared at the bottom of the knitted fabric.

In addition, the flatness of the knitted fabric was not good as a result of sudden death in an array of 3: 3 array and 4: 4 array.

Therefore, at this time, use the two-stage four-sided circular knitting machine only two stages. As a result of setting the feeding arrangement method at the ratio 2, fewer bones appeared at the bottom of the fabric, and the flatness of the fabric after the pretreatment was good.

On the other hand, in the process of maintaining the tension of the yarn and the density of the knitted fabric, the general yarn for double-sided circular knitting machine maintains a constant tension from the feeding device to the knitting needle, so that there is almost no twisting or cutting of the yarn. In the process of supplying thread until delivery, defects or cuts of the knitted fabric by twisting should be prevented in advance.

In addition, a lid with an appropriate tensioning device should be fitted to prevent cuts caused by scratches on the bobbin surface.

In addition, the fabric density of the dough has a significant effect on the density and elasticity of the tissue determined during the pretreatment process and should be adjusted according to the type and type of machine.

Therefore, when the yarn 75D / 36DTY yarn is cut in a 30 x 26G double-sided kneader, the density of the knitted fabric is adjusted to be between 185G and 190G per YD. As a result, a good result can be obtained in the pretreatment process and the printing process.

Example 3

The preprinting process of the printing material of the printing material is the shrinking processing of the knitted fabric first, and when the pretreatment process is completed, the width of the fabric is reduced as close as possible. It is difficult to obtain and make up for it, and it is hard to reduce the width in tenter processing, and if the tissue is forcibly formed, the elasticity of the fabric is increased and the elastic recovery power is reduced. Slip phenomenon of the tissue occurs, which is different from the content that wants an effect such as span.

Therefore, at this time, the temperature and time of the shrink processing of the printing material using polyester yarn can be reduced at 135 ° C. and 90 minutes to utilize the desired characteristics.

On the other hand, tenter processing should be set up so as not to reduce the width of fabric more than 2in after shrink processing.

In addition, to prevent excessive shrinkage of the fabric due to the high temperature during the processing of the tenter, to maintain a smooth touch (touch) of the fabric, and to maintain a uniform temperature and processing speed to prevent wrinkles and form safety.

In addition, after the tenter processing is sufficiently cooled to prevent wrinkles of the fabric.

As described above, the present invention transfers the conventional twisted yarn to a circular knitting machine that is used only in a direct yarn at a 2: 2 magnification ratio, thereby forming a fabric of naturally stretchable fabric without having to sew rubber yarn on the fabric fabric as in the prior art. It is effective.
