The Rayon Fibre Process and Fibre Characteristics.
Rayon fiber, which is a manmade fiber composed of regenerated cellulose consists of chains of sugar units and are identical to cotton in their molecular structure. The three methods of manufacturing rayon fibers are the viscose, cuprammonium, and Tencel processes. The viscose process is by far the most widely used. The Tencel process, whi..
Current Status and Future Trends in the Worlwide Industrial Uses of Nylon
Although the manmade fiber industry has grown significantly through its history, the demand for the natural fibers, cotton and wool, remain very high. However, the low costs and improved performance properties of manmade fibers represent a major competitive advantage over natural fibers. Nylon fiber is notable for its elastic recovery, ab..
The Present Status and Prospects of Korean Chemical fiber Industry.
In 1959, the first manmade fiber manufacturing facility in South Korea produced polyvinyl alcohol staple. Since then, the industry has grown significantly and added capacity for a range of fiber types, including nylon filament, viscose filament (discontinued in 1993), acrylic staple, polypropylene filament and staple, polyester filament a..
Angora Wool and Acrylic Fibres.
An investigation examined the physicochemical properties of angora rabbit hair and acrylic fibers, including fiber length, strength, elongation, diameter, crimp, microscopic appearance, moisture content, alkali damage, and the effect of various chemicals on the fibers. Research evaluated two types of rabbit hair samples, fine hair and gua..
Improvements Through Breeding in Naturally Colored Cotton
The emphasis of the cotton breeding program at Natural Cotton Colours is to improve the color range, fiber quality, and yields of naturally colored cottons. The breeding program works extensively with two cotton species: Gossypium hirsutum and Gossypium barbadense. To prevent contamination, crossed plants are grown in an isolated region o..
Polyester recycle
The nature of wastes from the manufacture of polyester bottles and ways in which their characteristics can be matched to end-use applications are discussed. Recycling takes place from every stage of the manufacturing process. Destinations appropriate to wastes from these stages are indicated including fibre production. Post-consumer recyc..
New variety of cotton seed
The Pakistan Central Cotton Committee received a new variety of American upland cotton seed called Chandni in order to conduct its own evaluation process. After completing the evaluation, it will be sent to the Provincial Seed Council for approval. Chandni has high yielding potential, heat tolerance and early maturing capabilities with st..
실내 공기의 질과 섬유 (긴급과제)
최근, 우리의 건강에 영향을 줄 수 있는 실내공기의 질(IAQ)에 관심이 고조되고 있다. IAQ에 관여하는 여러가지 인자중 본고에서는 섬유분야에 한정하여, 실내오염의 원인과 대책에 대해 문헌 소개와 함께 서술하였다. 섬유에 관계된 IAQ의 오염 원인에는 제1차 방출과 제2차 방출이 있다. 제1차 방출에는 미가공직물, 가공제, 염색공정잔사 등이 대상이 된다. 섬유..
합성섬유폐기물로 보드를 제조하기 위한 새로운 기술
1967년 Kuester가 applicator를 개발한 이후로 카핏을 연속식으로 염색하게 되었다. 그 결과 세계적으로 카핏의 생산량은 급격히 증가하였다. 1993년에는 약 1,700×1000000㎡의 카핏이 서방에서 생산되었고, 유럽에서만 약 750×1000000㎡에 달하였다. 유럽의 카핏을 20m 폭의 띠로 만들면, 적도를 일주할 수 있을 정도이다. 이정도의 제품이 언젠가 폐기물로 되어 버..
인조섬유를 혼합한 텍스타일의 새로운 재이용법
텍스타일 폐기물의 재이용법에는 여러가지 방법이 있지만, 본보에서 제시한 방법은 TITK(독)에서 검토되고 있는 합성섬유[폴리에스테르(E), 나일론(N), 아크릴(A)]와 면(C), 레이온(R)의 혼방품에서 합성섬유 성분을 간단히 분리하고, 이것을 부직포로 재이용하는 방법이다. 실험실 규모로 다음에 나타낸 것과 같이 여러가지 처리로 합성섬유 성분을 분리하고, 재생..
