The first filament yarn 120 is repeatedly arranged in the transverse direction with the first annular portions 130, 130 and the second claws 140 having rings formed thereon are arranged in the lateral direction and repeatedly arranged.

That is, the cotton knit fabric 100 having improved functionality according to the preferred embodiment of the present invention is combined and knitted into two pieces of the polyester filament yarns 110 and one piece of the cotton component-containing yarns 120.

That is, two chambers are combined at a ratio of 2: 1.

At this time, it is preferable that the surface component-containing chamber 120 includes 100% by weight of the surface.

The functionalized cotton knit fabric 100 includes 25 to 30% by weight of the polyester filament yarn 110 and 70 to 75% by weight of the cotton component containing yarn 120.

The polyester filament yarn 110 has a strong constitution, is not wrinkled well, and its shape does not change well. Knitted fabric 100 having improved functionality is prevented from being produced when the cotton knit fabric 100 having improved functionality is joined by bonding the polyester filament yarn 110 to the cotton component containing chamber 120, It is possible to prevent the phenomenon of shrinking or stretching after washing.

That is, by bonding the polyester filament yarn 110 to the cotton component-containing chamber 120, the disadvantages of the existing cotton knitted fabric can be compensated.

1, the annular portion formed by the face component containing chamber 120 is denoted by the first annular portion 130, and the annular portion formed by the polyester filament chamber 110 is denoted by the second annular portion 140. [

The polyester filament yarn 110 is disposed inside the first loop part 130 and the first loop part 130 is connected to the first loop part 130 in the lateral direction, And second rings 140 each having a ring formed thereon are connected in the lateral direction and are repeatedly arranged.

FIGS. 2 to 4 are structural cross-sectional views and knitting process diagrams of a functionalized cotton knit knitting machine 160 according to a preferred embodiment of the present invention.

A knitted fabric 100 having improved functionality according to an embodiment of the present invention includes a needle bed 150 having a plurality of knitting needles 155 arranged in a straight line, a needle bed 150 parallel to the needle bed 150, A cam carriage 156 which reciprocates on the needle bed 150 and a yarn carrier rail 151 which moves on the yarn carrier rail 151 and which is wound on the knitting needle 155 of the needle bed, Knitted fabric knitting machine 160 having a function of providing a yarn carrier that linearly feeds yarn.

A method used for knitting the cotton knit fabric 100 having improved functionality is as follows.

The first step is a yarn supplying step using a cotton component-containing chamber 120 as an outer surface yarn and a polyester filament chamber 110 as a base inner surface.

The second step is a yarn carrier aligning step in which each needle provided in the two yarn carriers 152 is spaced apart at a predetermined interval.

At this time, the gap between the front needle 153 and the rear needle 154 spaced apart from each other by a predetermined distance from the front needle 153, which is spaced apart from the front needle 153 by a predetermined distance, is about 2 to 3 mm, There are about seven needle bed knitting needles 155 in the interval.

Here, the predetermined interval is the difference between the front needle and the back needle.

When the polyester filament yarn 110 is completely knitted into the inner surface of the knitted fabric 100, the polyester filament yarn 110 is not visible on the outer surface of the knitted fabric 100, Knit knitted fabric 100 is prevented from being deformed such as slackening or stretching.

In addition, despite the rough characteristics of the polyester filament yarn 110, the touch of the existing cotton knit fabric 100 is maintained.

On the other hand, when the yarn-containing yarn 120 and the polyester filament yarn 110 are simply knitted together, the polyester filament yarn 110 is partially knitted on the outer side surface to make the outer surface rough, 100).

The third step is a yarn carrier moving step in which the yarn and the under yarn are respectively hooked to the nose portion of the needle aligned by the yarn carrier aligning step and moved in a straight line.

At this time, the cotton component-containing chamber 120 and the polyester filament chamber 110 are engaged with the nose portion of the front needle 153, which is positioned at a predetermined distance from each of the needles provided in the two yarn carriers 152, And the cotton component-containing chamber 120 and the polyester filament chamber 110 are engaged with the nose portion of the rear needle 154, which is spaced apart from the rear needle 154 by a predetermined distance.

In the fourth step, the cam carriage 156 is operated according to a preset knitting program to knit the yarn and the base yarn while the knitting needles 155 of the needle bed are driven in a zigzag manner.

At this time, the yarn on the outer side is set such that the first ring part 130 is formed and the second ring part 140 formed on the inner side is formed.

In addition, the cam carriage 156 is reciprocated on the needle bed 150 to set the needles 155 of the needle bed to be driven in a zigzag manner.

The polyester filament yarn 110 is knitted to the inner surface of the surface component-containing chamber 120 by the knitting program set to be knitted as described above.

That is, when the knitted cotton knit 100 is knitted by the knitting method, the polyester filament yarn 110 is completely knitted on the inner surface of the yarn containing compartment 120.

On June 9, 2014, the applicant commissioned the KOTERI (hereinafter referred to as "testing organization") to conduct quality testing of knitted knitted fabrics, and from June 9, 2014 to June 12, 2014 The test was conducted on June 12, 2014, and the test report for the test was issued.

(Test Example 1 - Tensile Strength)

Name of sample Cotton + PET if Slope (N) 452.8 242.5 Weft (N) 233.0 122.9

The test item is the gravure method (KS K 0520: 2009), which is the tensile strength test method of fabric.

Here, the tensile strength refers to the maximum load applied to the test piece by pulling the test piece until it is broken, pulling the fibers in the weft direction, which is the widthwise direction of the fabric and the warp direction, Record the load.

Polyethylene terephthalate (PET) bonded with cotton was tested by grabbing method. The slope direction was 452.8 N, the weft direction was 233.0 N, and the surface was tested to find that the slope direction was 242.5 N, 122.9 N.

The results show that the knitted fabric knitted with the cotton component-containing chamber 120 and the polyester milker 110 bonded together has a tensile strength higher than the tensile strength of the knitted fabric knitted only with the cotton component-containing chamber 120, It can be seen that it has excellent effect.

(Test Example 2 - Morphological stability after washing)

Name of sample Cotton + PET if Distortion (%) 0.8 2.7

The test item is a test method (KS K ISO 16322 2: 2009) that measures warpage after washing of the fabric.

Here, the warp means the state of the fabric in which the weft of the fabric is not perpendicular to the edge or the side line of the fabric and forms the inclination angle, and the degree of the warp of the fabric after three washes is recorded through the warping test method.

The combination of cotton and PET was tested and found to have a warpage of 0.8% after washing. Cotton was tested and found to be 2.7% warped after washing.

This result shows that the knitted fabric knitted by combining the cotton component-containing chamber 120 and the polyester mil yarn chamber 110 is less warped than the knitted fabric knitted only with the cotton component-containing chamber 120, It can be seen that the stability is excellent.

(Test Example 3 - Peeling Occurrence)

Name of sample Cotton + PET if class 3 One

The test item is the Martin Dale peeling test technique (KS K ISO 12945-2: 2008), which is a method of peeling test of fabrics.

Herein, peeling refers to a phenomenon in which a ball, which is a tangled fiber entanglement, is formed which has a density that can not penetrate through the surface of a fabric due to abrasion from the outside and has a density that can not transmit light. Filling and surface changes caused by abrasion of the fiber are visually judged and classified.

At this time, when the fabric is rubbed 2,000 times, the fabric which has not been formed at all is given grade 5, and the fabric which is densely formed on the surface is given the grade 1.

The combination of cotton and PET was tested by the Martin Dale peeling test method and received grade 3, and the cotton was tested and received grade 1.

This result shows that the knitted fabric knitted with the cotton component-containing chamber 120 and the polyester-milk chamber 110 combined has less effect than the knitted fabric knitted only with the cotton component-containing chamber 120 .
