A Simple Method for Measuring the Potential Resuspension of Dust from Carpets in the Indoor Environment

Carpets have an important influence on the comfort of room occupants in the indoor environment, but dust accumulating in carpets due to insufficient cleaning may have an adverse effect on indoor air quality. An easy-to-use method for evaluating the clean ing quality of carpets has been developed in this study, based on the resuspension of..

인도, 스판덱스 생산 시작

인도의 Indorama 사는 자국에서 스판덱스를 생산하기 시작하였다. 히마찰 프라데쉬주(Himachal Pradesh state)의 바디(Baddi) 지역에 위치한 스판덱스 공장의 총 생 산량은 15,000 톤/년 규모로, 이는 3단계로 이루어질 것으로 예상된다. 초기 생산량은 2012년도에 5,000톤이고, 2013년도에는 5,000톤이 추가로 생산될 예정이다.

Dynamic Moisture Vapor Transfer Through Textiles Part III: Effect of Film Characteristics on Microclimate Moisture and Temperature Changes

This study investigates the influence of semipermeable functional films on the sur face vapor pressure and temperature of fabric-film-fabric assemblies. The film added between two fabric layers affects vapor pressure and temperature changes on both surfaces of the assembly under simulated body-clothing conditions. The physical char acteri..

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..

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 ..
