Description

Manufacturing Method of Hanji Peeling {METHOD FOR MANUFACTURING COVERING YARN USING KOREAN PAPER}

The present invention relates to a method for manufacturing Hanji coated yarn which can produce Hanji coated yarns having excellent weaving and knitting properties as well as excellent physical properties such as elongation. And a step of forming the hanji coat by twisting the yarn with a twisting machine after weaving the tensioned hanji tape yarn.

In general, Hanji coating coated on the surface of Hanji is a fiber fashion material which is very beneficial to the human body, which is excellent in antibacterial and deodorizing properties, enables far-infrared emission, and is an environmentally friendly material that has recently been spotlighted for its excellent absorption and quick drying.

In connection with the copying of Hanji, Japanese Unexamined Patent Publication No. 2002-194642 and Utility Model Registration No. 20-0352850 have been proposed.

First, in Japanese Patent Laid-Open Publication No. 2002-194642 (branch knit fabric), a problem occurs when weaving and knitting, as the width of the branch yarn which is the surface yarn is 10 mm and the weight is excessively large as 30 g / m 2. In other words, the woven fabric is rough to the touch and poor appearance, the fabric is too thick to limit the end use. In addition, since knitting is difficult in knitting, there is a problem in that the appearance of the knitting is extremely poor as the knitting efficiency is very low, thereby greatly limiting the end use.

Also, registered utility model No. 20-0352850 (Hanji covering yarn) is limited to Hanji tape yarn in the range of 500 ~ 1500 denier, so that only thick and coarse woven fabric can be produced, and high value-added fine fabric or knitted fabric is impossible. Do. In addition, polyurethane elastic yarn was used as a screening, and Hanji tape yarn was used as a surface yarn to prepare a general covering machine. In particular, Hanji tape yarns in the range of 500-1500 denier have a width of 5 to 15 mm when the weight of hanji is based on 15 g / m2, and the hanji covering yarns made using these hanji tape yarns are woven and knitted fabrics. And the appearance is extremely poor and is greatly limited in the end use, and there is a problem in particular stable knitting work is impossible or very low knitting efficiency.

The present invention for solving such a conventional problem is not only excellent in weaving and knitting, but also excellent in physical properties, such as elongation, the production method of Hanji coating of which can be used for a variety of applications. The purpose is to provide.

The present invention for achieving the above object,

a) judging the armed force and weaving Hanji tape yarn with a tension of 15-35g;

b) twisting the plywood with a twisting machine to form hanjipi radiation; It provides a method for manufacturing Hanji coating of the radiation comprising a.

The step b) is to provide a method for manufacturing Hanji coating of the yarn characterized in that the step of forming the hanji skin by supplying the moisture after the yarn by the twisting yarn.

In addition, the hanji tape yarn of step a) is preferably a basis weight of 10 ~ 15g / ㎡, the width is 1 ~ 6mm.

Hereinafter, the manufacturing method of the Hanji coating of the present invention will be described in detail.

The manufacturing method of the Hanji coat of the present invention comprises a step of enlarging and twisting step.

First, the plying step is a step of plying the tension of the hanji tape yarn with the tension test, so that the screening is not protruded to the outside in the twisting step.

As the screening, various kinds of yarns can be used depending on the use purpose such as filament yarns and spun yarns such as silver nano polyester filament yarn having antimicrobial properties, and are not limited thereto.

The Hanji tape yarn is plied with the screening in a state in which a tension of 15 to 35 g is applied. When the tension is given to the Hanji tape yarns less than 15g, the screening part partially protrudes during the weaving step, so that friction between the heald and the body occurs during weaving or friction between the knitting needles during weaving, resulting in rapid weaving and knitting efficiency. There is a problem that decreases, and when the tension is given to more than 35g there is a problem that occurs frequently during trimming.

As a method for applying tension to the Hanji tape yarn, various methods can be used, such as supplying tension by supplying the Hanji tape yarn between an up-disc tensioner and a down-disc tensioner.

  In addition, it is preferable that the Hanji tape yarn has a basis weight of 10 ~ 15g / ㎡, the width of 1 ~ 6mm.

When the basis weight of the Hanji tape yarn is less than 10g / ㎡ there is a problem in that the productivity is not good because the trimming occurs frequently during the screening and weaving in a state in which the tension is applied, if the basis weight is more than 15g / ㎡ twist in the twisting step Since there is a problem that can not be given, it is better to use a Hanji tape yarn having a basis weight of 10 ~ 15g / ㎡.

In addition, using a width of less than 1mm by using the Hanji is not only difficult to cut smoothly using the slitter, there is a problem that the trimming occurs frequently when applying tension and twist, the width of the Hanji tape yarn more than 6mm If it is made, the twisted yarn is not uniformly given during the twisting step, so that the surface of the coated yarn is not only rough but also has a problem of poor knitting due to the fact that the screening is partially scattered on the surface. Hanji tape yarn is recommended.

On the other hand, in the step of the coordination of the tension and the tension of the 15 ~ 35g of the Hanji tape yarn wound to a separate bobbin after winding the yarn step, as well as the examination of the tension and the tension is After weaving the given Hanji tape yarn can be subjected to the continuous step of course of course.

Next, the twisting step is to produce a Hanji coat by applying a twist while simultaneously coating the depth of the Hanji tape yarn of the plywood using a twisting machine.

In particular, it is preferable to form the Hanji coat by supplying water after the yarn is twisted with a twisting machine in order to obtain a Hanji coat with excellent uniformity.

As a method of supplying water, there is a method of spraying water onto the Hanji coats radiated by the above-mentioned twisting machine, a method of immersing the Hanji coats in water, a method of passing the Hanji coats through water vapor, and the like.

As described above, the Korean paper coating manufactured by the Korean paper coating manufacturing method of the present invention is uniformly coated with the Hanji tape yarn in a state where the screening does not protrude on the surface, so that the uniformity is excellent. This has the advantage of obtaining soft and good looking fabrics and knitted fabrics.
