Description
본 발명은 합성수지 단섬유의 제조방법에 관한 것으로, 더욱 상세하게는 폴리부틸렌테레프탈레이트 수지로 된 모노필라멘트를 수산화나트륨 수용액에 침지하여 감량가공하므로써 천연모와 같이 부드러움 및 신축성을 가지는 합성수지 단섬유를 제조하는 방법에 관한 것이다.The present invention relates to a method for producing synthetic resin short fibers, and more particularly, to prepare synthetic resin short fibers having softness and elasticity as natural hair by immersing monofilament made of polybutylene terephthalate resin in an aqueous solution of sodium hydroxide to reduce the weight. It is about how to.
일반적으로 인조모에 천연모와 유사한 물성을 부여하기 위해서는 압출성형에 의하여 제조된 모노필라멘트를 기계적인 가공방법을 사용하여 그 형태를 바꾸어 주는 데, 이러한 기계적인 가공방법은 가공공정이 어렵고 제조된 인조모도 일정하지 못하고 또한 섬세하지 못하여 천연모가 가지는 부드러움 및 신축성을 부여할 수가 없다.In general, in order to give the artificial hair similar properties to natural hair, the shape of the monofilament produced by extrusion molding is changed by using a mechanical processing method. This mechanical processing method is difficult to process and the manufactured artificial hair is uniform. It is not able to provide the softness and elasticity that natural hair has.
이에 본 발명자들은 합성수지 모노필라멘트를 녹일 수 있는 용매를 이용하여 합성수지 모노필라멘트의 일부분을 녹여냄으로써 천연모와 같은 부드러움 및 신축성을 유지하면서 용도개발이 용이한 인조모를 얻을 수 있음을 알게 되어 본 발명을 완성하였다.The present inventors have completed the present invention by knowing that by dissolving a part of the synthetic resin monofilament using a solvent capable of dissolving the synthetic resin monofilament, an artificial hair can be easily obtained while maintaining its softness and elasticity such as natural hair. .
본 발명의 목적은 합성 모노필라멘트를 사용하여 물성이 천연모와 유사한 인조모를 제조하는 데 있다.An object of the present invention is to use synthetic monofilament to produce artificial hair similar in physical properties to natural hair.
이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명은 폴리부틸렌테레프탈레이트 수지로 된 모노필라멘트를 일정 길이로 절단한 후 농도 20~40%, 온도 100~130℃의 수산화나트륨 수용액에 2~3시간 침지시킴을 특징으로 하는 합성수지 단섬유의 제조방법이다.According to the present invention, a monofilament made of polybutylene terephthalate resin is cut to a predetermined length and then immersed in a sodium hydroxide aqueous solution having a concentration of 20 to 40% and a temperature of 100 to 130 ° C. for 2 to 3 hours. It is a manufacturing method.
이하, 본 발명을 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.
본 발명은 합성수지 모노필라멘트를 감량 가공하기 위한 방법으로서, 먼저 압축 성형한 폴리부틸렌테레프탈레이트 합성수지 모노필라멘트를 일정한 길이로 절단한다. 이 때 모노필라멘트의 직경을 조절함으로써 용도를 여러 가지로 변경할 수 있다.The present invention is a method for weight-reducing a synthetic resin monofilament, and first, a polybutylene terephthalate synthetic resin monofilament which is compression molded is cut into a predetermined length. At this time, the use can be changed in various ways by adjusting the diameter of the monofilament.
절단된 모노필라멘트를 일정량씩 묶음으로 하여 수산화나트륨 수용액에 침지하여 감량가공한다.The cut monofilament is bundled in a fixed amount and immersed in an aqueous sodium hydroxide solution to reduce the weight.
여기서 수산화나트륨 수용액의 온도는 100~130℃, 농도는 20~40%, 침지시간은 2~3시간 정도가 바람직하며, 침지깊이는 용도에 따라 조절할 수 있으나 20~60mm정도가 바람직하다.The temperature of the aqueous sodium hydroxide solution is 100 ~ 130 ℃, the concentration is 20 ~ 40%, the immersion time is preferably about 2 to 3 hours, the immersion depth can be adjusted depending on the application, but preferably about 20 ~ 60mm.
만일, 온도가 낮거나 농도가 낮으면 감량이 적게 이루어져 제품으로서의 가치가 없고, 온도가 높거나 농도가 진할 경우에는 가공이 너무 빨리 이루어져 모의 끝이 뾰족하게 나오지 않아 촉감이 부드럽지 못해 제품으로서 적용할 수 없으며, 침지깊이는 제품의 신축성에 영향을 미친다.If the temperature is low or the concentration is low, the weight loss is low and it is not worth the product. If the temperature is high or the concentration is too high, the processing is too fast and the tip of the hair does not come out sharply, so the touch is not soft. Immersion depth affects the elasticity of the product.
또한, 침지시간이 너무 짧으면 감량이 적게 이루어지고, 침지시간이 너무 길면 모피 끝이 굽어지는 현상이 발생하여 제품으로 적용할 수 없다.In addition, if the immersion time is too short, the weight loss is made less, if the immersion time is too long, the end of the fur is bent phenomenon can not be applied to the product.
따라서, 이러한 조건들의 조화가 중요하다.Therefore, the harmony of these conditions is important.
이상과 같은 본 발명의 조건으로 침지할 경우에 감량의 정도가 15~25%로 되어 적당한 바, 감량은 필라멘트의 특성상 끝부위, 즉 침지시킨 밑부분부터 감량이 많이 되어 침지 끝이 뾰족한 형태로 된다.When immersed under the conditions of the present invention as described above, the degree of weight loss is 15 to 25%, and the weight is moderate, and the weight loss is increased from the end of the filament, i. .
이상에서 설명한 바와 같은 본 발명에 따르면 천연모와 같은 신축성과 부드러움을 가지는 인조모를 얻을 수 있으며, 화장용 브러시, 화필류, 페인트 브러시 등의 용도로 유용하다.According to the present invention as described above, it is possible to obtain a synthetic hair having the same elasticity and softness as natural hair, and is useful for use in cosmetic brushes, paintbrushes, paint brushes, and the like.
이하, 본 발명을 실시예를 통하여 더욱 구체적으로 설명하겠는 바, 본 발명이 실시예에 의해 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited to the Examples.

표 1에 나타낸 것과 같이 수산화나트륨(NaOH)농도, 온도, 침지시간을 달리하고, 침지깊이 40mm로 하여 인조모를 생산하였다.As shown in Table 1, the concentration of sodium hydroxide (NaOH), temperature, and soaking time were varied, and artificial hairs were produced at an immersion depth of 40 mm.
이렇게 얻어진 폴리부틸렌테레프탈레이트 인조모를 세척하고 헹구어 용해된 슬러지 및 제품에 묻은 수산화나트륨 성분을 제거하고 온도 50℃에서 24시간열풍 건조시킨 후, 제품의 직경을 부위별로 길이 5mm단위로 측정, 모노필라멘트의 감량정도를 측정하였다.The polybutylene terephthalate artificial hair thus obtained was washed and rinsed to remove dissolved sludge and sodium hydroxide from the product, followed by hot air drying at a temperature of 50 ° C. for 24 hours. The diameter of the product was measured in units of 5 mm in length for each part. The degree of loss of was measured.
