본 출원은, 2005년 9월 6일에 출원된 임시 출원번호 60/713,758의 우선권에 관한 것이고, 이를 청구한다.This application is related to and claims the priority of provisional application No. 60 / 713,758, filed September 6, 2005.
본 발명의 배경 및 분야Background and Field of the Invention
본 발명은, 일반적으로, 수분 관리 특성이 향상된 제품을 제공하기 위한 조성물 및 프로세스에 관한 것이다. 보다 구체적으로, 본 발명은, 다른 바람직한 물성의 치명적인 손실 없이 향상된 수분 관리 또는 위킹 특성을 보이는 폴리에스테르계 섬유와 폴리아미드계 섬유를 제공하는 조성물 및 프로세스에 관한 것이다. 본 발명의 섬유는, 직물과 마루바닥재 응용에 사용되어도 된다.The present invention generally relates to compositions and processes for providing products with improved moisture management properties. More specifically, the present invention relates to compositions and processes for providing polyester based and polyamide based fibers that exhibit improved moisture management or wicking properties without lethal loss of other desirable physical properties. The fiber of the present invention may be used for fabric and flooring applications.
합성 섬유는, 일반적으로 수분을 효율적으로 나를 수 없는 능력으로 괴로움을 겪는다. 섬유의 위킹 특성의 개선은, 많은 응용에서 매우 바라는 것이다. 예를 들면, 효율적인 위킹 섬유를 비롯한 의류 제품 등의 직물 응용에서는, 착용자에게 편안함을 보다 크게 인식하게 하기도 한다. 마루바닥재 응용에서는, 샴푸 및 세척한 후 마루바닥재를 건조할 때 향상된 위킹 특성이 도움이 되기도 한다. 추가로, 향상된 위킹은, 마루바닥재면으로부터 백킹(backing)으로 떨어져서 우연히 수용성의 보기 흉한 염색의 전송에 도움이 되어서, 그 염색을 보지 못하게 한다. 우리가 발명한 새로운 조성물은, 직물 및 마루바닥재 제조시에 사용된 수분 위킹 폴리에스테르 섬유와 폴리아미드 섬유를 제공할 때 매우 효과적이고 경제적인 것이다.Synthetic fibers generally suffer from their inability to carry moisture efficiently. Improvements in the wicking properties of fibers are very desired for many applications. For example, in textile applications such as apparel products, including efficient wicking fibers, it also makes the wearer more aware of comfort. In flooring applications, improved wicking properties may also be helpful when drying flooring after shampooing and washing. In addition, the improved wicking helps to transfer water soluble unsightly stains back to the backing from the flooring surface, making the staining invisible. The new composition we invented is very effective and economical when providing moisture wicking polyester fibers and polyamide fibers used in the manufacture of fabrics and flooring materials.

상기 예시 1-3에서 제조한 얀을, 약 3-4 oz/yd2의 양말로 서큘러 니팅하였다. 물 전송률을 다음과 결정하였다: 그 물 전송률은, 소위 수직 스트립 위킹 시험에 따라 측정한다. 양말의 일단(약 4인치 폭 × 12인치 길이)을 21℃의 증류수에서 약 1/4인치 침지된 댕글링 엔드(dangling end)와 수직으로 고정하였다. 물을 (주행된 거리) 인치마다 스트립을 따라 전송하는데 걸린 시간을 측정하였다. 주행된 거리당 시간이 짧을수록 액체의 물 전송 능력이 보다 커진다.The yarn prepared in Example 1-3 was circularly knit with about 3-4 oz / yd 2 of socks. The water transfer rate was determined as follows: The water transfer rate is measured according to the so-called vertical strip wicking test. One end of the sock (approximately 4 inches wide by 12 inches long) was fixed vertically with a dangling end immersed in about 1/4 inches in distilled water at 21 ° C. The time taken to transfer water along the strip every inch (distance traveled) was measured. The shorter the time per distance traveled, the greater the water transport capacity of the liquid.

The prepared POED masterbatch was reduced to nylon 6,6 with RV = 3.1 on a direct fiber-spun extruder and then stretched and entangled two yarn ends to give 1200 / 60Y BCF yarns.
상기 예시 4-6에서 제조한 얀은, 서큘러 니터(knitter) 상에서 유사한 구성의 양말로 짰다. 상기 물 수송률은, 양말마다 상술한 것과 유사한 방법으로 결정하였다. 그 결과를 표 2에 나타내었고, 도 2에 그래프적으로 도시하였다. 본 발명의 예시 4 및 6에서는, 본 발명이 아닌 예시 5에 대해서 현저하게 높은 물 위킹률을 보였다.The yarn prepared in Example 4-6 was squeezed into a sock of a similar configuration on a circular knitter. The water transport rate was determined in a manner similar to that described above for each sock. The results are shown in Table 2 and graphically shown in FIG. In Examples 4 and 6 of the present invention, a significantly higher water wicking rate was shown for Example 5 than for the present invention.
