Definitions

  • the present invention relates to a dyeing method using a UV ray curing method which may be used irrespective of materials from a common clothes fiber to an industrial fiber the color revelation of which is difficult, in a color formation method wherein any medium is not used in a wet dyeing method using a medium, for example, water or a solvent.
  • the present invention relates to an environmentally friendly dyeing method.
  • the color revelation process of the fiber is formed of a dope dyeing process wherein a dye is added to a material during the manufacturing of a fiber, a high temperature dyeing process wherein a dyeing is carried out in a yarn or woven fabric, and a coating process wherein a preparation is carried out with a pigment and a dye.
  • the method for a color formation with the aid of a dope dyeing is a method wherein a solid state fiber, for example, a regeneration, a semi-synthesis, a synthetic fiber, etc. except for a natural fiber is transformed into a liquid state through dissolution or melting, and pigment is added.
  • a phase change is very hard, and a discoloring problem may occur due to a rough condition for a phase change. Since the number of colors is limited, such a method is employed only for a special case. Moreover, the use thereof is very limited due to a high cost.
  • the high temperature dyeing process is a most common process wherein a dye penetrates in a non-crystal region of a fiber formed of polymers, and a color can be revealed through a reaction or absorption.
  • a chemical for example, a levelling agent, an additive, and acid or alkali regulator will be added, and a high heat is necessary for the sake of easier penetration of dye, thus revealing a desired color.
  • a fiber material is formed of one component, the above mentioned method would be a very useful method.
  • a dye selection, a dyeing process and a post-process condition may change for each fiber material. For this reason, a lot of water is used, which may result in a big economical load with respect to the process of waste water.
  • the color coating process may have an advantage in terms of a low cost and various color revelations thanks to a conventional high temperature heat hardness, but a friction fastness is very weak due to a failure in an adhering force between a fiber and a coating liquid, and a high temperature heat should be used for a heat melting of a resin or an impregnation of a low viscosity resin and a heat hardness method, whereupon a lot of problems may occur during the process, which may cause a slow production, thus resulting in a low possibility for mass production.
  • a cotton, a wool, a hemp cloth, etc. are natural fibers, and a rayon fiber reproduced through a chemical change in terms of the natural fiber may be classified as a regenerated fiber.
  • a synthetic fiber there are a polyethylene terephthalate (PET), a polyethyleneterephthalate (PTT), a cation dyeable PET (CDP), a nylon, an acrylic fiber, a spandex fiber, etc.
  • PET polyethylene terephthalate
  • PTT polyethyleneterephthalate
  • CDP cation dyeable PET
  • the cellulose natural fiber can be color-revealed with a reactive dye
  • a wool, silk, and nylon fiber can be color-revealed with an acid dye
  • an acryl and modacryl fiber can be color-revealed with a cation dye
  • a PET fiber can be color-revealed with a distribution dye.
  • the fibers used for the purpose of industry are fibers with enhanced physical properties, heat resistance or other functions. Since such fibers cannot be easily color-revealed using a dye, other additives, heated water, etc., they are called a hard-to-dye fiber.
  • these fibers there are polyethylene (PE) and polypropylene (PP) fibers, and as a high performance industrial fiber, there are glass fiber, ultra high molecular weight polyethylene (UHMWPE), aramid fiber, carbon fiber, polyimide (PI), polybenzoxazole (PBO), polybenzimidazole (PBI), etc. which belong to a high strength, high heat resistance fiber, so such fibers are generally used for the purpose of industry rather than the purpose of clothes due to the above-mentioned problems.
  • PE polyethylene
  • PP polypropylene
  • glass fiber ultra high molecular weight polyethylene
  • aramid fiber carbon fiber
  • PI polyimide
  • PBO polybenzoxazole
  • PBI polybenzimidazole
  • the physical properties of the targeted product may change in accordance with components. If dye or pigment is mixed in silica, which is a main ingredient, during the crude liquid coloring process for the sake of color revelation, the color revelation may not be carried out since it is impossible to estimate any change in a product's physical property.
  • PP fibers which are polyolefin fibers, there is not any functional group which may react with dyes, so color revelation is hard.
  • a high performance fiber for example, a UHMWPE, aramid, PBO, PBI, etc.
  • the penetration of dyes is not easy, so color revelation becomes harder.
  • carbon fiber is formed of only carbons in structure through a carbonization process, the fiber itself is a deep shade black, so color revelation may not be carried out.
  • the color revelation can be possible through a dyeing process wherein a superhydrophobic dye is synthesized by substituting an alkyl group, which is similar with a fiber polymer, with a base component of a conventionally available dispersion dye.
  • any change in the physical property of the fiber itself may be caused during the dyeing process wherein a high temperature heat water is used because of a low heat resistance of the fiber itself, and the mass production and commercialization of dyes are impossible, so the above newly developed dye may not apply to other hard-to-dye fibers, thus making difficult the further development thereof. Therefore, it is necessary to invent a new color revelation process with respect to the hard-to-dye fiber on which it is difficult to form dyes through a crude liquid coloring process or a dyeing process which belong to the conventional color revelation processes.
  • the color revelation should be carried out under a condition where the change of natural physical property of the fiber is small, and commercialization is easy, and cost is low.
  • a clothes fiber is not used alone. More specifically, two or more than two clothes fiber materials are used together or a blended product of a clothes fiber material and an industrial fiber material is used a lot. In this case, the dyeing process may become complicated, and the use of water will increase, which results in the increased amount of waste water. For this reason, the use of the industrial fiber material is limited. Given the above described situation, the coating process may be most preferred so as to reveal a desired color irrespective of the kinds of materials.
  • thermosetting process among the color revelation processes has a problem in terms of the durability of a coating layer due to a friction, and productivity.
  • a color may be coated on a fiber using a UV ray curing method. Since the UV ray curing method can be carried out in seconds or minutes, the productivity can be enhanced, and the fastness against friction can be increased with the aid of a smooth surface formation. This method can be employed to a heat sensitive fiber material.

  • the method for dyeing a fiber yarn according to the present invention is a method wherein a yarn formed of a clothes and industrial fiber material is impregnated in a UV ray-cured coating liquid, and a thin film coating layer is formed, and a UV ray-cured coating liquid is cured.
  • a pigment and a UV ray-cured type resin are mixed at a predetermined concentration for the sake of color revelation, and a UV ray is radiated, and the mixed liquid is cured, thus curing a fiber yarn the color of which has been revealed.

  • the amount of UV ray-cured type monomer is smaller than 90% by weight, a problem may occur in the fastness due to a bad adhering force of the coating liquid, and if the amount thereof is greater than 98.5% by weight, a problem may occur in a color revelation and physical property due to the decrease amount of coloring or oligomer.
  • the amount of the UV ray-cured type oligomer is smaller than 1% by weight, a color revelation may be difficult due to the decreased amount of coloring of the coating layer for a lower viscosity, and a tactile feeling may feel hard.

If the compression is carried with a high pressure, a too thin film may be formed or a non-coated portion may occur partially, for which the uniformity of color may be degraded. If the compressing is carried with a lower pressure, the coating layer may become too thick. In this case, the uniformity of the coating layer may be degraded due to the flow of the liquefied coating liquid after it is cured.
