본 발명은 상술한 목적을 위해 창안된 것으로,The present invention was made for the above-mentioned purposes,
폴리헥사메틸렌·테레프탈아미드수지를 주성분으로 하는 수지섬유로 형성되는 것을 특징으로 하는 세정용 브러쉬 롤의 브러쉬모재에 관한 것이다. 아울러 본 발명상의 브러쉬모재는 수지섬유중에 실끊어짐방지용 첨가제가 포함되며, 또한 상기 폴리헥사메틸렌·테레프탈아미드수지를 주성분으로 하는 수지섬유로 형성된 브러쉬모재를 구비하므로써 세정용 브러쉬 롤의 브러싱부재를 제조할 수 있도록 한 것을 특징으로 한다.The brush base material of the brush roll for cleaning characterized by being formed from the resin fiber which has a polyhexamethylene terephthalamide resin as a main component. In addition, the brush base material according to the present invention includes an additive for preventing thread breakage in the resin fiber, and further comprising a brush base material formed of a resin fiber mainly composed of the polyhexamethylene terephthalamide resin to prepare a brush member for cleaning brush rolls.

발명의 실시형태Embodiment of the invention
본 발명에 사용되는 폴리헥사메틸렌·테레프탈아미드수지는 하기 식으로 표현되는 구조를 가지는 폴리아미드수지이다.The polyhexamethylene terephthalamide resin used for this invention is a polyamide resin which has a structure represented by a following formula.
(화 1)(Tue 1)
이 폴리헥사메틸렌·테레프탈아미드수지는 폴리헥사메틸렌지아민과 테레프탈산을 기본골격으로 가지고, 고융점(高融点), 고유리전이점(高glass轉移点), 저흡수율(低吸水率)을 나타낸다.This polyhexamethylene terephthalamide resin has polyhexamethyleneziamine and terephthalic acid as a basic skeleton, and has a high melting point, high glass transition point, and low water absorption.
특히, 유리전이점은 100∼120℃ 으로, 이 수지를 이용하여 형성한 브러쉬모재는 고온(예를 들면 60∼80℃)의 세정액을 스프레이하면서 세정하는 경우라도 브러쉬모재의 수지섬유가 부드러워지지않아 세정능력이 저하되지 않는다.In particular, the glass transition point is 100 to 120 ° C, and the brush base material formed by using this resin does not soften the resin fibers of the brush base material even when cleaning with spraying a high temperature (for example, 60 to 80 ° C) spraying solution. Detergency does not decrease.
또한, 흡수율이 낮기 때문에 사용시(흡수시)에 수지섬유의 탄성(彈性)(굽힘 경도(硬度))이 저하되기 힘들다. 수지섬유의 바람직한 흡수율은 3∼5% 정도이다.In addition, since the water absorption is low, the elasticity (bending hardness) of the resin fiber during use (absorption) hardly decreases. Preferable water absorption of the resin fiber is about 3 to 5%.
수지섬유를 형성하는 수지성분은 폴리헥사메틸렌·테레프탈아미드수지만으로도 좋고, 나이론 6, 나이론 66 등의 다른 폴리아미드수지를 병용하여도 좋다. 다른 폴리아미드수지의 사용량은 수지성분중의 30 중량% 이하인 것이 바람직하다.The resin component forming the resin fiber may be only polyhexamethylene terephthalamide resin, or other polyamide resins such as nylon 6 and nylon 66 may be used in combination. It is preferable that the usage-amount of another polyamide resin is 30 weight% or less in a resin component.
그리고, 수지섬유의 내 실끊어짐성(耐絲折性)을 높이기 위하여 흑연가루(黑鉛粉), 금속화합물휘스커(예를 들면 티탄휘스커), 카본화이버, 글래스화이버, 실리콘등의 실끊어짐방지용 첨가제를 첨가하여 수지섬유를 형성하여도 좋다. 이들 첨가제는 1 종 단독으로 사용하여도 좋고, 2 종 이상을 병용하여도 좋다. 바람직한 첨가제는 흑연가루, 금속화합물휘스커등이다. 실끊어짐방지용 첨가제의 크기로서는 1∼60㎛ 정도의 것이 좋고, 5∼15㎛ 정도의 것이 보다 바람직하다. 실끊어짐방지용 첨가제의 첨가량은 0.05∼5 질량% 정도가 좋고, 0.05∼1 질량% 정도가 보다 바람직하다.In order to increase the break resistance of the resin fibers, additives for preventing breakage of graphite powder, metal compound whiskers (for example, titanium whiskers), carbon fibers, glass fibers, silicon, etc. May be added to form a resin fiber. These additives may be used individually by 1 type, and may use 2 or more types together. Preferred additives are graphite powder, metal compound whiskers and the like. As a size of the thread break prevention additive, about 1-60 micrometers is preferable, and about 5-15 micrometers is more preferable. About 0.05-5 mass% is good, and, as for the addition amount of the thread break prevention additive, about 0.05-1 mass% is more preferable.
수지섬유를 형성할 때 예를 들면, 상기 수지성분의 필요에 대응하여 실끊어짐방지용 첨가제를 혼입하여, 통상의 용융압출방사법(溶融押出紡絲法)에 의해 방사하면 좋다. 방사된 수지섬유는 필요에 의해 연신(延伸)한다.When forming the resin fiber, for example, in response to the needs of the resin component, a thread breaking prevention additive may be mixed and spun by a conventional melt extrusion method. The spun resin fiber is stretched as necessary.
1 올의 브러쉬모재는 1 올의 모노필라멘트로 구성되어도 좋고, 여러 올의 모노필라멘트를 묶어서 구성하여도 좋다. 1 올의 모노필라멘트로 구성하는 경우, 그 모노필라멘트의 직경은 통상 0.3∼1.0㎜ 정도이며, 여러 올의 모노필라멘트로 구성하는 경우, 각 모노필라멘트의 직경은 통상 0.01∼0.5㎜ 정도이다.The brush base material of one ool may be comprised by one oar monofilament, and may be comprised by tying several oar monofilament. In the case of a monofilament of 1 ol, the diameter of the monofilament is usually about 0.3 to 1.0 mm, and in the case of a monofilament of several ols, the diameter of each monofilament is usually about 0.01 to 0.5 mm.

When the cell tape as a blank was measured as it was, the L value was 90.42, and the L value when the steel sheet was completely cleaned (degreasing) was 89.45.
도 2 에 계측한 결과(3 회 평균치)를 나타내었다. 도 2 에서 횡축(橫軸)의 라인스피드는 강판이 브러쉬 롤의 밑을 통과한 속도이다.The measurement result (three times average value) is shown in FIG. In Fig. 2, the horizontal line speed is the speed at which the steel sheet passes under the brush roll.
도 2 에서 나타나 있는 바와 같이, 실시예 1 의 브러쉬 롤 A 및 실시예 2 의 브러쉬 롤 B 는 비교예 1 의 브러쉬 롤 C(종래품)와 비교하면 월등히 우수한 세정성능을 가진 것임을 알 수 있다.As shown in FIG. 2, it can be seen that the brush roll A of Example 1 and the brush roll B of Example 2 have an excellent cleaning performance compared to the brush roll C of the comparative example 1 (conventional product).
다음으로 실시예 1, 2 및 비교예 1 에서 얻어진 수지섬유(A, B, C)의 내 실끊어짐성(耐絲折性)을 평가하기 위하여 이하의 실끊어짐 촉진시험을 하였다.Next, in order to evaluate the thread breaking resistance of the resin fibers (A, B, C) obtained in Examples 1, 2 and Comparative Example 1, the following thread breaking acceleration test was carried out.
외경 320㎜ 의 원반의 외주에 길이 10㎜ 의 수지섬유 A, B 및 C 를 각 15 올, 방사상으로 고착하였다. 이 원반을 1200 rpm 으로 회전시키고, 1m/분의 속도로왕복운동하는 철판을 압하량 1㎜ 로 브러싱하였다. 브러싱할 때에 60℃ 의 물을 철판에 스프레이하였다.Resin fibers A, B, and C each having a length of 10 mm were fixed to the outer circumference of a disk having an outer diameter of 320 mm in a radial manner of 15 balls each. The disk was rotated at 1200 rpm, and the iron plate reciprocating at a speed of 1 m / min was brushed with a reduced amount of 1 mm. 60 degreeC water was sprayed on the iron plate at the time of brushing.
연속운동시의 실끊어짐 올수를 도 3 에 나타내었다.The number of thread breaks during continuous movement is shown in FIG. 3.
도 3 에서 나타나 있는 바와 같이 실시예 2 에서 얻어진 수지섬유 B 는 내 실끊어짐성(耐絲折性)에 있어서, 비교예 1 로 얻어진 수지섬유 C(종래품)와 비교하여도 손색이 없다. 또한, 실시예 1 로 얻어진 수지섬유 A 는 100 시간 연속운전한 경우의 내 실끊어짐성에 있어서 뒤떨어지고, 50 시간정도의 연속운전의 경우에는 실용상의 문제는 없다. 그리고 실시예 1 로 얻어진 수지섬유 A 는 압하량을 보다 미소(微小)하게 한 경우에는 실용상의 문제는 없었다.As shown in FIG. 3, the resin fiber B obtained in Example 2 is inferior in thread breaking resistance compared with the resin fiber C obtained by the comparative example 1 (traditional product). In addition, the resin fiber A obtained in Example 1 is inferior in the thread breaking resistance at the time of 100 hours of continuous operation, and there is no practical problem in the case of continuous operation of about 50 hours. And the resin fiber A obtained in Example 1 had no practical problem, when making the reduction amount smaller.
본 발명의 세정용 브러쉬 롤의 브러싱부재는 전술한 바와 같이, 고온(예를 들면 60℃∼80℃)의 세정액을 스프레이하여 세정하는 경우에도 브러쉬모재의 수지섬유가 부드러워지지 않아 우수한 세정능력을 나타냄을 알 수 있다.As described above, the brush member of the cleaning brush roll of the present invention does not soften the resin fiber of the brush base material even when sprayed and cleaned with a high temperature (for example, 60 ℃ to 80 ℃) exhibits excellent cleaning ability It can be seen.
