본 발명은 페인트 브러쉬용 합성수지 모노필라멘트의 제조방법에 관한 것으로, 더욱 상세하게는 폴리에틸렌테레프탈레이트 수지(이하, "PET"라 한다.)와 폴리부틸렌테레프탈레이트 수지(이하, "PBT"라 한다.)를 각각 단독 혹은 블랜드(blend)하여 스타휘시 단면형태의 모노필라멘트를 제조한 후 감량가공하여 천연모에 가까운 페인트 브러쉬용 모노필라멘트를 제조하는 방법에 관한 것이다.The present invention relates to a method for producing a synthetic resin monofilament for a paint brush, and more particularly, a polyethylene terephthalate resin (hereinafter referred to as "PET") and a polybutylene terephthalate resin (hereinafter referred to as "PBT"). The present invention relates to a method for producing monofilaments for paint brushes, which are close to natural hair, after the monofilaments of starfish cross-sectional shape are manufactured by weight loss processing, alone or blended).

일반적으로, 폴리에스테르를 압출성형하여 제조된 모노필라멘트의 형태를 기계적 작업방법에 의해 변경을 실시하고 있으나 가공하기 어렵고 감량가공시 감량길이가 부족하여 천연모가 가지는 부드러움, 신축성을 가지기가 어려워 페인트 브러쉬용으로 적용되기가 어려운 문제점을 해결할 수 없었고, 아울러 천연모를 색상선택이 제한적이고 형태가 다양하게 적용되기가 어려웠다.In general, the shape of the monofilament produced by extrusion molding polyester is changed by a mechanical working method, but it is difficult to process and lacks the length of weight loss during weight reduction, so it is difficult to have the softness and elasticity of natural hair. It was difficult to solve the problems that were difficult to apply, and it was difficult to apply a variety of forms and colors to natural hair.

이에 본 발명자는 PBT, PET 또는 PBT/PET 얼로이를 방사하여 얻은 모노필라멘트를 감량용액을 이용하여 모노필라멘트의 일부분을 녹여 냄으로써 천연모와 유사한 부드러움, 신축성을 유지하면서 페인트 브러쉬용으로 용이한 인조모를 얻을 수 있음을 알게 되어 본 발명을 완성하기에 이르렀다.Accordingly, the present inventors dissolve a portion of the monofilament using a weight loss solution of the monofilament obtained by spinning PBT, PET or PBT / PET alloy to obtain a faux hair for paint brushes while maintaining softness and elasticity similar to that of natural hair. It was found that the present invention was completed.

이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.

본 발명은 PET, PBT 또는 PET/PBT 얼로이를 단면이 대칭형인 네발 스타휘시(Starfish) 형태인 방사공을 통하여 압출하여, 외측 대각 꼭지점간의 거리(a)가 0.3~0.5mm이고 내측 대각 꼭지점간의 거리(b)가 0.1~0.2mm인 단면이 대칭형인 네발 스타휘시 형태인 모노필라멘트를 제조하고, 제조된 모노필라멘트를 일정길이로 절단한 후 농도 15~45%의 NaOH 수용액 또는 KOH 수용액에 80~160℃ 온도에서 0.5~3시간 침지, 감량시켜 감량부분의 길이가 0.2~30mm이고 감량부분의 단면이 원형형태가 되도록 하는 것을 특징으로 하는 페인트 브러쉬용 합성수지 모노필라멘트의 제조방법에 관한 것이다.The present invention extrudes a PET, PBT or PET / PBT alloy through a radial hole in the form of a symmetrical four-foot Starfish, the distance between the outer diagonal vertices (a) is 0.3-0.5 mm and the distance between the inner diagonal vertices. (b) 0.1-0.2mm cross-sectional symmetrical four-foot staple shape monofilament was prepared, and the monofilament was cut to a predetermined length and then 80-160 in NaOH or KOH aqueous solution of 15-45% concentration It relates to a method for producing a synthetic resin monofilament for a paint brush, which is immersed and reduced at a temperature of 0.5 to 3 hours so that the length of the weight reduction portion is 0.2 to 30 mm and the cross section of the weight reduction portion is circular.

이하, 본 발명을 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.

본 발명에서 PET 수지로는 고유점도가 0.5~2.0인 것을 사용하고, PBT 수지로는 용융온도가 210~240℃이고, 고유점도가 0.6~2.0(페놀/TCE법 측정)인 것을 사용하여 단독 또는 이들의 폴리머 얼로이를 방사기에서 방사온도 230~280℃에서 일정한 형태 및 일정한 굵기로 압출성형을 실시한다. 모노필라멘트의 직경은 0.3~0.5mm가 페인트 브러쉬용으로 적용 가능하며 모노필라멘트의 단면형태는 스타휘시 모양을 적용한다.In the present invention, a PET resin having an intrinsic viscosity of 0.5 to 2.0 is used, and as a PBT resin, a melting temperature of 210 to 240 ° C and an intrinsic viscosity of 0.6 to 2.0 (phenol / TCE method measurement) are used alone or These polymer alloys are extruded with a constant shape and a constant thickness at a spinning temperature of 230 to 280 ° C. in a spinning machine. The diameter of the monofilament is 0.3 ~ 0.5mm applicable to the paint brush and the cross section of the monofilament is applied to the starfish shape.

PET 70~80%와 PBT 20~30%의 폴리머 얼로이를 사용하여 인조모를 제조하는 경우에 있어서, PBT의 함량이 80%를 초과하면 압출 성형시 방사 압력을 높게하여야 하고, 제조된 모노필라멘트를 감량가공할때 너무 많은 부분이 감량되는 문제점이 있다.In the case of manufacturing artificial hair using 70 ~ 80% PET and 20 ~ 30% PBT polymer alloy, when the content of PBT exceeds 80%, the spinning pressure must be increased during extrusion, and the produced monofilament is reduced. There is a problem that too much portion is lost when processing.

또한, PET의 함량이 30% 초과하면 압출후 모노필라멘트의 형태가 매끄럽지 못하고, 제조된 모노필라멘트를 감량가공하면 감량길이에 차이가 심하게 발생하는 문제점이 있다.In addition, when the content of PET exceeds 30%, the form of the monofilament is not smooth after extrusion, there is a problem in that the weight loss process is severely reduced when the monofilament produced.

본 발명의 스타휘시단면의 모노필라멘트의 생산 방식이 기존의 원형단면을 가지는 모노필라멘트의 생산 방식과 다른 점은 다른형태의 방사구금을 사용하며, 압출성형시 온도가 기존의 생산방식보다 10℃ 가량 높고, 방사후 모노필라멘트의 형태가 스타휘시 모양을 유지하기 위해 스핀블럭의 온도를 기존의 생산방식보다 5℃ 가량 낮게하는 것이다. 이러한 생산방식을 거쳐 제조된 모노필라멘트를 낮은 연신비율로 연신하면 도면과 같이 단면형태를 가진 모노필라멘트를 제조할 수 있다.The production method of the monofilament of the starfish cross-section of the present invention is different from the production method of the monofilament having a conventional circular cross-section using a different type of spinneret, the extrusion temperature is about 10 ℃ than the existing production method It is high, and the shape of the monofilament after spinning is to keep the temperature of the spin block about 5 ℃ lower than the conventional production method to maintain the star shape. When the monofilament produced through such a production method is stretched at a low draw ratio, it is possible to produce a monofilament having a cross-sectional shape as shown in the drawing.

압출성형한 합성수지 모노필라멘트는 감량가공이 용이하게 다발로 묶은 다음 일정한 길이(20~110mm)로 절단하여 감량가공 용액에서 감량 가공한다.The extruded synthetic resin monofilament is easily weighted and bundled into bundles, cut into lengths (20 ~ 110mm), and reduced in weight loss solution.

감량가공에 사용할 수 있는 용액으로는 NaOH 수용액, KOH 수용액, 오르쏘클로로페놀 수용액, 테트라클로로 에틸렌 수용액 등이 있으며, NaOH 수용액, KOH 수용액이 특히 효과적이다.Solutions that can be used for weight reduction are NaOH aqueous solution, KOH aqueous solution, orthochlorophenol aqueous solution, tetrachloroethylene aqueous solution, and the like, and NaOH aqueous solution and KOH aqueous solution are particularly effective.

절단된 합성수지 모노필라멘트를 NaOH 용액에 일정시간, 일정온도하에서 감량가공을 실시한다. 이러한 방법에서 중요한 점은 알카리 수용액의 농도, 온도, 침지시간, 침지깊이이다. 이러한 조건들이 적합하지 않을 경우에는 천연모의 특성을 가지는 용도에 맞는 물성의 제품을 얻을 수 없다.The cut synthetic resin monofilament is subjected to weight reduction processing at a constant temperature for a certain time in NaOH solution. The important points in this method are the concentration, temperature, soaking time and soaking depth of the alkaline aqueous solution. If these conditions are not suitable, it is impossible to obtain a product of a physical property suitable for use with the characteristics of natural hair.

본 발명에 따른 인조모는 다음 조건에서 제조될 수 있는 바, 즉 온도 80~160℃, NaOH용액 농도 15~45%, 침지시간 0.5~3.0시간, 형태는 스타휘시 모양이 바람직하며, 침지깊이는 페인트 브러쉬의 크기에 따라 조절할 수 있으나 주로 5~70mm 정도가 적당하다.Artificial hair according to the present invention can be prepared in the following conditions, that is, the temperature is 80 ~ 160 ℃, NaOH solution concentration 15 ~ 45%, immersion time 0.5 ~ 3.0 hours, the shape is preferably a star shape, immersion depth paint It can be adjusted according to the size of the brush, but 5 ~ 70mm is suitable.

제품으로서는 감량후의 감량부분이 0.2~30mm가 가장 바람직하며 감량된 끝부분의 모양은 원형이나 미감량 부분은 스타휘시 모양이어야 한다.As for the product, the weight loss part after weight loss is most desirable 0.2 ~ 30mm, and the shape of the weight loss end should be circular, but the weight loss part should be starfish shape.

페인트 브러쉬용으로 감량길이 및 형태가 중요한데 감량가공이 일정부분만 적당하게 되어야 함으로, 온도가 낮거나 농도가 낮을 경우에는 감량시간이 길어지고 감량이 적게 이루어져 스타휘시 모양이 그대로 남아 있어 페인트시 좋은 점을 찾을 수 없어 요구하는 제품을 얻을 수 없고, 온도가 높거나 농도가 진할 경우에는 감량이 너무 빨리 이루어져 감량이 많이 되고, 페인트 브러쉬 앞부분의 부피가 적어져 페인트의 함유량이 적어짐에 따라 제품으로서 적용할 수 없으며, 아울러 침지깊이는 제품의 신축성에 영향을 미친다.Weight loss length and shape are important for paint brushes, but only a certain part of weight loss processing should be suitable. In case of low temperature or low concentration, the weight loss time is long and the weight loss is small. If you can't find the product you need, you can't get the product you need, and if the temperature is too high or the concentration is too high, the weight loss is too fast and the volume is reduced. In addition, immersion depth affects the elasticity of the product.

또한 침지시간이 너무 짧으면 감량이 적게 이루어져 천연모에 가까운 물성을 나타낼 수 없고 스타휘시의 형태가 그대로 남아 페인트시 페인트의 양조절이 어렵고, 침지시간이 너무 길면 인조모 끝이 굽어지는 현상이 발생하며 감량부분이 과다하게 길어지면 인조모의 상부 부피가 작아 페인트 브러쉬용으로 사용할 때 페인트 용액의 함유량이 적어지는 문제점이 발생하게 된다. 따라서 상기한 조건들간의 조화가 중요하다.In addition, if the immersion time is too short, the weight loss is small, so that the physical properties of the natural hair cannot be expressed, and the shape of the starfish remains intact, and it is difficult to control the amount of paint during painting. If the length is excessively long, the upper volume of the artificial hair is small, which causes a problem that the content of the paint solution decreases when used for the paint brush. Therefore, harmony between the above conditions is important.

또한 모노필라멘트의 단면형태는 원형, 마름모, 삼각, 육각, 팔각형, 스타휘시 모양 등을 다양하게 적용시킬 수 있는데 페인트용으로 스타휘시 모양의 필라멘트를 사용함이 신축성이나 촉감이 부드러우며 아울러 페인트용으로 사용할 때 사용하는 페인트 함유량이 높아 가장 우수하며, 그외 원형, 마름모, 삼각, 육각, 팔각형 등도 압출 성형하는데 문제점이 없고 신축성이나 촉감도 우수하며 사용목적에 적합하도록 감량가공에 적용시킬 수 있다.In addition, the cross-sectional shape of the monofilament can be applied to various shapes such as round, rhombus, triangular, hexagon, octagon, and starfish shape. It has the highest paint content, so it is the best, and there is no problem in extrusion molding of round, rhombus, triangle, hexagon, octagon, etc., and it has excellent elasticity and feel and can be applied to weight reduction processing to suit the purpose of use.

이상에서 설명한 바와 같이 본 발명에 의하면 제조된 페인트 브러쉬용 합성수지 모노필라멘트는 천연모가 가지는 신축성이나 부드러움을 가지면서 페인트의 사용목적에 적합하도록 페인트의 보유능력이 우수한 특성을 가지며 생산성 및 가격면 경쟁력이 우수한 제품을 얻을 수 있다.As described above, according to the present invention, the manufactured synthetic resin monofilament for the paint brush has characteristics of excellent paint holding ability to suit the purpose of use of paint while having elasticity or softness of natural hair, and excellent productivity and price competitiveness. You can get the product.
