Headspace Resistance Standards for the Shirley Developments Ltd. Micromat Tester High precision headspace resistance standards (HRS) are developed for the Micromat model of the Shirley Developments Ltd. fineness and maturity tester. The Micromat measures cotton fineness and maturity based on the principle of air permeability through a fixed mass of fibers at two different stages of compression. Differential pressures ..

Measuring Fiber Orientation in Nonwovens Part V: Real Webs This paper extends the work of the first four parts of this series to apply the image analysis methods we have developed to characterize the fiber orientation of real non woven fabrics. The "real" fabrics chosen as typical are a carded crimped fiber web, two relatively dense overall or area bonded fabrics, a pattern or point bonded spun b..

Image Analysis Tools to Study Nonwovens A device composed of a mechanical dynamometer and optical sensor coupled with image analysis software is designed to provide powerful tools to study the evolution of the nonwoven structure under stress. Images of the samples are recorded before undergoing mathematical analysis, and various parameters are calculated. The evolu tion of thes..

Measuring Fiber Diameter Distribution in Nonwovens This paper reports the application of image analysis methods we developed previ ously to characterize fiber diameter distribution in nonwovens using a "distance trans form." The method is verified by a series of simulated nonwoven images as well as some real web images used previously, including a carded web, a relatively dense spunbonded..

Dye-Surfactant Interactions Studied Using Job's Method Interactions between the anionic dye Acid Orange 7 and two cationic surfactants N- cetylpyridinium chloride (CPC1) and cetyltrimethylammonium bromide (CTMABr) in aqueous solutions far below the CMC are studied using the method of continuous variations, also called Job's method. Light absorbance in the visible spectral range is measured. B.. Home | News & Info | KOTITI 라이브러리 | 섬유기술정보 I 등록일 : 2012.11.16 I 조회수 : 237 |

Steady-State Unwinding of Yarn from Cylindrical Packages Over-end unwinding involves pulling yam from a fixed package to be used in textile processes such as knitting, sewing, twisting, weft insertion in weaving, and doubling. During unwinding, the yam slides on the package surface and lifts off into the balloon formed between the package and the guide eyelet. Variations in yam tension and bal ..

A modem control strategy including controller design and system output modifica tion is illuminated by application to feedback control of a carded web control system. Since the carded web system is a type-zero plant, an integrator in the feedforward path between the error comparator and the plant is inserted to improve the system type. A ..
