Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a fabric using a circular knitting machine,

More particularly, the present invention relates to a method of manufacturing a fabric using a circular knitting machine, and more particularly, to a method of manufacturing a fabric using a circular knitting machine, which can minimize shrinkage and stretchability during fabrication, The present invention relates to a method of manufacturing a fabric using a circular knitting machine,

(I) a yarn composed of PLA fibers (hereinafter referred to as "PLA yarn") and spandex, a latent yarn made of PLA yarn (Ii) a method for producing a composite yarn having elasticity by combining stretchable yarns having excellent elasticity, such as a knitted fabric or a polybutylene terephthalate yarn, and then using the composite yarn as a part or all of the yarn for manufacturing PLA fabrics, A method of imparting stretchability to a PLA yarn by using a method of texturing while extending a PLA yarn (DTY method), and then using the yarn-processed PLA yarn as all or a part of a yarn for PLA fabrication is known come.

On the other hand, the prior art in which a PLA yarn is manufactured by a DTY method and then used to manufacture a PLA fabric is difficult to exhibit sufficient stretchability, and in particular, a composite yarn in which PLA yarn and natural fiber or biodegradable fiber are combined, There has been a problem that the temperature is significantly lowered.

In recent years, Korean Patent No. 10-1223955 (a stretchable yarn including poly (lactic acid) fibers, a method for producing the same, and a fabric including the same) has been disclosed.

Such fabrics have the advantage of having environmentally friendly yet excellent stretch properties, including polylactic acid (PLA) fibers.

However, such a conventional fabric may be advantageous to the human body when it is manufactured and used as a bedding such as a futon, but it has a problem that the durability of the bedding is deteriorated due to high elasticity.

That is, when the conventional fabric is manufactured using a futon cover, the sewing portion can easily burst or the fabric tears in the process of using the futon (the user pulls the futon from both sides) according to high stretchability, The fabric is not fixed when sewing a heavy fabric, so it is difficult to sew and manufacture the quilting work, and there is a problem of a high defect rate.

In addition, a Velor fabric is proposed to overcome the above problems. Conventional velor fabrics were knitted using two kinds of yarns using plain polyester (DTY) alone knitted or natural fibers such as polyester and cotton, and they were widely used in the manufacture of clothes.

As shown in Fig. 1, the Velor fabric has a structure in which the polyester yarn 1 and the cotton yarn 2 are knitted and knitted in such a manner that their faces overlap each other in the longitudinal direction. At this time, the Velor fabric is composed of 20% by weight of polyester yarn and 80% by weight of cotton yarn with respect to 100% by weight of the total weight.

These existing velor fabrics have the advantage of soft feeling and natural fiber, and many companies have attempted to manufacture bed linen. However, they have encountered various problems such as weight, unit price, elasticity, width of fabric width, It has been pushed to microfiber fabrics and has not been used so far in the manufacture of bedding.

1. Original Beloa fabric is 400 ~ 450g per 60 yards (yd) and 400 ~ 450g as a heavy fabric that weighs more than 600g in 80 inch conversion rate for a comfortable bedding. (yd) is included in the required amount. If the bed is made of a sleeping quilt including cotton, there is a problem that the quilt costs 3.5kg more than 5kg.

In other words, the existing velor fabric is heavy, so it is not suitable for use as a futon, and a heavy futon can make the user feel various inconveniences such as obstructing the sleep of the user.

2. The existing velor fabric is heavy, so it is expensive compared to the micro fabric. In other words, since the unit price of the fabric is very close to the weight, the unit price is calculated in comparison with the weight. Accordingly, the Veloa fabric is not softer than the micro-fabric, as shown in the above 1, and is heavy and expensive.

In other words, Velor fabric is a fabric that does not have advantages compared to micro-fabric even though it is a natural fiber in the bedding industry. In fact, many companies are trying to manufacture Velor fabric as a substitute for micro-fabric, .

3. The existing Velor fabric has a good elasticity. In other words, Velor fabric has good elasticity, and it has been easily manufactured in high elasticity fabrics such as general clothing and sportswear. These properties are obvious advantages for fabrics, but they are a great negative factor in non-stretchable bedding. For example, when a quilt is fabricated with a fabric, it may be produced by turning it, or it may be impossible to manufacture, a problem of sewing when sewing, and deterioration of a product when the user uses the quilt.

4. Existing Velor fabric can not be manufactured in large size (85 inches or more). That is, in the case of bedding, the width size of one sheet is 85 to 90 inches on average. Veloa, which is 85 in Korea, has no serious problem unless it is mechanically renovated and it can not be mass-produced.

In other words, in order to make a comfortable bedding, it is necessary to fabricate a comfortable bedding by making the width (the process of making the widths by connecting the non-widthed fabrics together). As described in the above 3, There is a problem.

5. The existing velor fabric is similar to microfiber fabric with hairy fabric and it has the advantage of natural fabric. However, as shown in FIG. 2A, such a Velor fabric has a phenomenon in which the hairs are knitted by knitting at 45 degrees during the knitting process, and the hairs lie on one side as shown in FIG. 2B even after dyeing. When the hair is laid on one side, the one side is soft but when it is swept up the other side is very rough. Therefore, when the bedding is made, there is a problem that the user may feel nervous and feel as soft as microfiber.

6. Existing Velor fabric has a big disadvantage compared to fabrics with different shrinkage ratios. The fabric shrinkage rate is about 5 ~ 8%, and it is generally thought that the shrinkage rate is about 5% in the garment industry. Unlike clothing, the amount of fabric used in bedding is very high. If the shrinkage ratio is large, a large amount of fabric is contained therein, which also increases the unit price.

Therefore, it is required to research and develop a fabrication method and fabric of a fabric using a circular knitting machine which can be easily applied to a bedding requiring a reduction in shrinkage and elasticity during manufacture of a fabric, have.

Korean Registered Patent No. 10-1223955 (Registered Date: January 14, 2013)

The yarn preparing step S10 is a step of preparing an artificial yarn and a natural yarn for fabricating the fabric.

Herein, the artificial yarn is composed of a polyester (DTY) yarn 12 and a polyester yarn (POY) 14, and the natural yarn 16 is an eco-friendly yarn formed of cotton or other natural material do.

That is, the fabric 10 according to the present invention is obtained by knitting a polyester yarn (POY) mixed with a conventional Velor fabric composed of polyester (DTY) yarn and natural yarn mentioned in the prior art.

10 to 15% by weight of polyester (DTY) yarn 12, 20 to 30% by weight of polyester yarn (POY) 14, 20 to 30% by weight of natural yarn (16) in an amount of 55 to 70% by weight.

The polyester (DTY) yarn 12 is formed at 75 d to 150 d, and the polyester yarn (POYY) is formed at 20 s to 60 s. This is to minimize the shrinkage and stretchability of the fabric 10 during manufacture and to reduce the weight. Here, d is a denier indicating the thickness of the polyester (DTY) yarn 12 and the polyester yarn gauze (POYY) 14, and s is the thickness of the natural yarn 16 It is a symbol.

The fabric knitting step S20 is a step of knitting the polyester yarn 12, the polyester yarn POY 14 and the cotton or other natural material prepared in the yarn preparing step S10 And the natural yarn 16 is fed to the circular knitting machine to knit.

Although not shown in the figure, the circular knitting machine is formed by knitting a polyester (DTY) yarn 12, a polyester yarn gauze (POY) 14 and a natural yarn 16 and forming a fabric having a constant width and weight do. That is, the fabric 10 has a structure in which a polyester (DTY) yarn 12, a polyester yarn (POY) 14, and a natural yarn 16 are knitted together by a circular knitting machine.

That is, the fabric 10 is made of a polyester (DTY) yarn 12, a polyester yarn gauze (POY) 14 and a natural yarn 16 formed of a cotton or other natural material, They are knitted into a structure in which they are bound to each other by a circular knitting machine as shown in the figure. At this time, the loop of the fabric 10 is knitted in one direction by about 45 degrees.

This fabric 10 is knitted such that a polyester (DTY) yarn 12, a polyester yarn gauze (POY) 14 and a natural yarn 16 are connected in a ring form by a circular knitting machine, 10 can be reduced in weight.
That is, as shown in Fig. 4, the fabric is produced by knitting a polyester (DTY) yarn 12, a polyester yarn gauze (POY) 14 and a natural yarn 16, 16 are bound to each other in a ring shape so as to be arranged at regular intervals in the longitudinal direction and knitted, whereby the total weight of the fabric 10 can be reduced.

Here, the circular knitting machines are divided into small-sized and large-sized knitting machines.

In other words, the narrow width is composed of 22 g / g of 24 g / g and is used in the production of bed pads, and the width is 26 inches of 24 g / g.

In this case, g is the number of needles in an inch as a symbol indicating gauge. For example, in the case of a small-sized Velor knitting machine 22 inches 24 g / g, it means that it is composed of 22 inches x 3.14 x 24 = 1.657 needles.

As shown in FIG. 6, the fabric primary sharing step S30 is a step of shearing the fabric 10 knitted by the fabric knitting step S20.

That is, the fabric 10 knitted by the circular knitting machine has a polyester (DTY) yarn 12, a polyester yarn gauze (POY) 14 and a natural yarn 16 connected in the form of a ring, So that the upper part of the loop is cut and the cut yarn is sucked and removed. At this time, the reason for cutting the upper part of the loop is to form a hair that provides a soft touch on the surface of the fabric 10.

As shown in FIGS. 7A and 7B, the fabric dyeing step (S40) is a step of dyeing a fabric having fur on its surface by a primary initial sharing step (S30).

For this purpose, the fabric 10 is dyed by dipping in a high-temperature dye solution for a certain period of time. At this time, the fabric 10 is dyed by dipping in a dyeing solution having a temperature of about 100 ° C to 120 ° C for 2 hours or more so as to stain the entire fabric 10 uniformly. By this dyeing process, the fabric 10 is contracted by the cloth knitting step S20 in a state of being formed with a certain width. That is, the fabric 10 after the dyeing process is shrunk by 20% to 35% more than the polyester yarn 14 (POY) 14 by the first fabric knitting step S20 (S20) .

The fabric 10 also has polyester yarns 14 (POY, POY) 14 when the polyester yarn (POY) 14 is shrunk while the hairs are lying at about 45 degrees along with the shrinkage by the dyeing process The natural yarn 16 is pushed up by pushing up the polyester (DTY) yarn 12 between the polyester yarn 12 and the natural yarn 12 due to the shrinking force of the polyester yarn 14, (16) is formed more vertically than the existing Velor fabric.

The fabric drying step (S50) is a step of drying the dyed fabric (10) in a hot air of 100 to 180 DEG C for 1 hour to 1 hour and 30 minutes. At this time, the fabric 10 is dried by a large-sized drum washing machine that generates hot air, and thus is shrunk to a constant width as in the dying step S40.

The fabric drying step S50 is to completely dry the fabric 10 after the dyeing process, as well as to remove the dust particles contained in the hair to further soften the fabric.

The fabric primary working step S60 is a step of stretching the fabric 10 shrunk by the cloth dying step S40 and the cloth drying step S50 by stretching the cloth 10 to a predetermined width. In other words, the fabric 10 is shrunk after dyeing and drying, so that the width thereof is not constant. The fabric 10 is stretched to a predetermined width by a tenter so as to smoothly proceed to the next operation.

At this time, if the fabric 10 is made of a small-width circular knitting machine, it is corrected to a width of 50 to 55 inches, and if it is made of a large knitting machine, it is corrected to a width of 70 to 75 inches.

The fabric combing step S70 is a step of combing the hairs of the fabric matched in accordance with the fabric drying step S50. Through this combing process, the hair formed on the surface of the fabric 10 is uniformly spread over the entire surface without being gathered in various places.

The fabric second secondary shearing step S80 is a step of cutting the hair having irregular heights again to a constant height according to the cloth drying step S50 as in FIG. That is, in the far-end secondary shearing step (S80), hair ends are uniformly formed using a shearing machine.

The fabric secondary processing step S90 is a step of stretching the fabric 10 sharply supported by the second secondary shearing step S80 by a tenter to a desired width at a high temperature of 200 degrees and drying the fabric. At this time, the stretched polyester yarn (POY) 14 becomes a completely processed yarn through several thermal processes and becomes a yarn similar to a normal polyester (DTY) yarn 12. Accordingly, it can be manufactured as a fabric that can prevent stretching and shrinkage upon repeated washing.

At this time, if the fabric 10 is made of a small-width circular knitting machine, it is extended to a width of 65 to 75 inches, and if it is made of a large-size circular knitting machine, it is stretched to a width of 80 to 100 inches.

That is, the polyester yarn (POY) 14 constituting the fabric 10 is shrunk by the thermal process in the fabric dyeing step S40 and the fabric drying step S50, S60) and the fabric secondary processing step (S90), they do not shrink again when they are sequentially stretched by the tenter.

In addition, the polyester yarn (12) is dipped in a high-temperature dyeing solution while the polyester yarn (POY) 14 has a property of being highly shrunk by 50% or more by a high-temperature dyeing solution The stability and elasticity of the fabric 10 can be minimized by having stable properties such that the change of shrinkage is not large. This can be achieved by suppressing the shrinkage of the polyester yarn (POY) 14 with the polyester (DTY) yarn 12 to prevent the yarn 10 from being shrunk after being dyed and being distorted or unstable It will be.

By knitting and knitting the polyester yarn 12, the polyester yarn POY 14 and the natural yarn 16 formed of cotton or other natural materials as described above, It is possible to manufacture the fabric 10 which can prevent elongation and shrinkage during repetition.

Therefore, the fabric 10 using the circular knitting machine according to the present invention can be produced by the steps of preparing a polyester (DTY) yarn 12, a polyester yarn gauze (POY) 14 and a natural yarn 16, A fabric stitching step S40, a fabric drying step S50, a fabric primary processing step S60, a fabric combing step S40, a fabric finishing step S20, a fabric primary shearing step S30, (20 to 40% or more) larger than the width knitted by the first circular knitting machine in the fabric secondary manufacturing step (S90) after the fabric is manufactured by the second secondary shearing step (Z80) So that it can be used exclusively for the bedding that requires the expansion and contraction, and it is possible to prevent shrinkage and elongation and shrinkage in repeated washing.

The fabric 10 using the circular knitting machine according to the present invention can be manufactured by knitting a polyester yarn 1 and a cotton yarn 2 by knitting such that the yarns 2 are overlapped in a longitudinal direction, The natural yarns 16 are arranged at regular intervals in the longitudinal direction when the polyester yarn 12, the polyester yarn 14 and the natural yarn 16 are knitted together, The overall weight can be remarkably reduced while maintaining the soft effect of the Velor fabric, and the weight can be reduced.

The fabric 10 using the circular knitting machine according to the present invention is different from the structure of the conventional Velor fabric in which the polyester yarn 1 and the cotton yarn 2 are knitted together, (POY, POY) 14, which is relatively inexpensive and less costly than the conventional method, can be manufactured.

8 to 11 are photographs showing the result of measurement of the stretchability of the fabric using the circular knitting machine according to the present invention after knitting, dyeing, processing and washing processes, FIG. 8 is a photograph of the fabric knitted by the circular knitting machine at the fabric knitting step FIG. 10 is a photograph of a fabric stretched by a tenter in a fabric processing step, and FIG. 11 is a photograph of a fabric after a fabric is shrunk after washing It is a photograph seen.

As shown in Fig. 8, the fabric 10 is knitted in a fabric knitting step S20 by a circular knitting machine, and a polyester yarn 12, a polyester yarn yarn (POY) 14, (16) were mixed and knitted to a width of 180 cm.

As shown in FIG. 9, the fabric 10 knitted by the circular knitting machine was immersed in a dyeing solution of 80 to 120 deg. C for 2 hours or more in the fabric dyeing step (S40) and then dried. At this time, the fabric 10 was dried and then shrunk to a width of 130 cm.

That is, it was confirmed that the fabric 10 shrank about 28% from the width of the fabric knitting step S20 after the fabric dyeing step S40.

As shown in FIG. 10, the cloth 10 was stretched to 216 cm in width by using a tenter in the fabric secondary processing step S90 after the cloth dying step S40.

That is, it can be confirmed that the fabric 10 is stretched by about 40% from the width of the fabric 10 contracted by the fabric dyeing step S40 after the fabric processing step S90.

As shown in Fig. 11, the raw fabric 10 was stretched by a fabric secondary working step (S90), washed and dried. At this time, the fabric 10 was dried and contracted to a width of 206 cm.

That is, it was confirmed that the fabric 10 shrank by about 4% after the washing process, compared to the width of the fabric secondary fabricating step S90.

Therefore, as described above, the fabric 10 using the circular knitting machine according to the present invention is suitable for a bedding that is required to prevent expansion and contraction, and can be used exclusively.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious to those who have. Accordingly, such modifications or variations should not be individually understood from the technical spirit and viewpoint of the present invention, and modified embodiments should be included in the claims of the present invention.
