Description

Carbon fiber branch with excellent dyeability and its manufacturing method {PAPER YARN CONTAINING CARBON FIBER AND MANUFACTURING METHOD THEREBY}

The present invention relates to a carbon fiber branch having excellent dyeing properties, and in detail, having excellent properties such as antimicrobial, deodorizing, adsorptive, electromagnetic shielding and antistatic properties of carbon fiber, it is possible to prepare a pre-dyed yarn and dye when dyeing after dyeing The present invention relates to a carbon fiber branch having no stain and excellent washing resistance.

As the conventional method for producing a branch using functional fibers, the method of using a base paper mixed with functional fibers only in the first paper machine is the simplest method.However, when carbon fibers are used, dyeing defects appear due to the intrinsic color of carbon fibers, that is, black. There was a problem that some carbon fibers are dropped out.

In the case of using a single paper machine, the base paper including fibers having a primary color, such as the carbon fiber produced in the first paper machine, has a primary color (black color) according to the mixing ratio of the carbon fibers. In general, when about 10% of the carbon fiber is mixed, the base paper becomes pale black, and when more than 30% forms a dark black. When the branch is made with carbon fiber paper manufactured using such carbon fiber and then dyed after dyeing or after fabric is made, the color of black is maintained as it is, resulting in dyeing defects such as dyed stains.

The present invention for solving such a conventional problem, even if the mixing ratio of the carbon fiber is used more than 10% does not appear dying defects such as stain stains, inherent in the antimicrobial, deodorizing, adsorptive, electromagnetic shielding and antistatic of the carbon fiber It is an object of the present invention to provide a method for producing a carbon fiber branch which can easily produce a carbon fiber branch having a characteristic.

The present invention for achieving the above object, the paper tape formed by cutting a double paper obtained by laminating a base paper made of pulp and carbon fiber paper to a certain width so that one surface made of carbon fiber paper of the surface of the paper tape is located inside. It provides a carbon fiber yarn having excellent dyeability, characterized in that prepared by applying twist.

The basis weight of the base paper consisting of the pulp is preferably 8 ~ 40g / m ² .

In addition, the present invention comprises the steps of: a) laminating a base paper made of pulp and carbon fiber paper to obtain a double paper;

b) cutting the duplex paper into a predetermined width to obtain a paper tape;

c) adding a twist to the paper tape; provides a method of producing a carbon fiber paper yarn having excellent dyeing characteristics comprising a.

In addition, the basis weight of the base paper made of the pulp of step a) is preferably 8 ~ 40g / m ² .

In particular, the step c) is preferably applied to the paper tape twisted so that one surface made of carbon fiber paper of the surface of the paper tape is located inside.

And, in the step a), it is preferable to obtain a double paper by laminating and drying the paper in the wetland state which is papered and conveyed in the first paper machine, and the carbon fiber paper in the wetland state which is papered and conveyed in the second paper machine.

In addition, the step a) is a wet paper state of papermaking and conveyed in the first papermaking machine, the carbon fiber paper of the wetland state, which is previously laminated or transferred to the first papermaking machine, and the paper produced in advance After laminating, the double paper can be obtained by drying. In addition, water can be sprayed on one surface of a pre-prepared base paper or carbon fiber paper, and then laminated with carbon fiber paper or base paper, respectively, and dried to obtain a double paper.

Hereinafter, described in detail with respect to the manufacturing method of the carbon fiber yarn excellent dyeability of the present invention.

The method for producing a carbon fiber paper yarn having excellent dyeability of the present invention comprises a double paper forming step, a paper tape forming step, and a flammable step.

First, the double paper forming step is a step of obtaining a double paper by laminating the base paper and the carbon fiber paper made of pulp.

The pulp is composed of pulp obtained from coniferous trees, broadleaf trees, etc., in the algae, and then sufficiently beaten, dried and then dried, and in particular, to obtain light weight raw paper, such as mulberry fiber, manilama fiber, etc. It is good to use the raw paper obtained by using.

In particular, the basis weight of the base paper consisting of the pulp is preferably 8 ~ 40g / m ² . If the basis weight is less than 8g / m ^2, the dyeability of the produced carbon fiber yarn is not good, if the weight is more than 40g / m ² there is a problem that can not obtain a high quality carbon fiber yarn because the twist is not uniformly given.

The carbon fiber paper includes not only carbon fiber paper made of 100% carbon fiber but also carbon fiber made by mixing other fibers with carbon fiber. In detail, carbon fibers may be used by mixing shredded fibers, hemp fibers, and manilamar fibers.

Carbon fiber constituting the carbon fiber paper has excellent properties such as antibacterial, deodorant, adsorptive, electromagnetic shielding and antistatic.

As a method of obtaining a double paper by laminating the base paper and the carbon fiber paper made of the pulp, 1) by spraying water on one surface of a pre-prepared base paper or carbon fiber paper and then laminated and dried to obtain a double paper Method; 2) Method of laminating paper or carbon fiber paper in wetland state, which is papermaking in papermaking machine, and carbon fiber paper or papermaking paper prepared and dried to obtain double paper; and 3) Papermaking and conveying paper in first papermaking machine. There is a method of obtaining a double paper by laminating the wet paper in the wetland state and the carbon fiber paper in the wetland state being transferred and transferred from the second paper machine.

All of the methods of obtaining the above double paper can be laminated with a base paper and carbon fiber paper without using a binder, there is an advantage that can smoothly give a twist in the combustion step.

In particular, the third method of the above method is to produce a double paper by laminating continuously in the process of manufacturing the base paper and carbon fiber paper, the productivity is excellent, the first paper machine, the second paper machine can use a long paper paper machine or ring paper paper machine have.

The paper tape forming step is a step of forming a paper tape on a tape by cutting the duplex paper to a predetermined width. The method for cutting the double paper into a constant width is not particularly limited, but it is preferable to cut in the longitudinal direction using a rotary slitter device having a plurality of rotary blades set in advance according to the width to be cut. The cutting width of the double paper is determined by the properties of the double paper and the properties of the carbon fiber yarn to be obtained.

The twisting step is a step of obtaining a carbon fiber yarn by twisting the paper tape obtained by the paper tape forming step, and twisting the paper tape using a spinning machine, a twisting machine, or the like to obtain a carbon fiber yarn.

At this time, since the paper tape is made by cutting the double paper, it is preferable to add moisture to the paper tape immediately before applying twist to the spinning machine or the like in order to prevent uneven twisting.

In addition, in order to further improve the dyeability, by twisting the paper tape so that one surface made of carbon fiber paper in the surface of the paper tape is located inside to obtain a carbon fiber yarn.

It is possible to provide a carbon fiber yarn and a fabric having a sufficient durability against repeated washing, and can be dyed while preventing the color of the carbon fiber even by directly dyeing the carbon fiber yarn manufactured as described above, or dyeing the fabric made using the same. have.

The carbon fiber branch manufacturing method of the present invention does not show dyeing defects such as staining stains even when the blending ratio of carbon fiber is 10% or more, and the unique characteristics such as antimicrobial, deodorizing, adsorptive, electromagnetic shielding and antistatic of carbon fiber There is an effect that can be easily produced carbon fiber branch having.
