Uster Tester 검사 항목에 대하여.

안녕하십니까? 원사 uster, 균제도 검사시에 나오는 항목 때문에 골머리를 아파하고 있습니다. 테스터기 마다 나오는 항목이 조금씩은 다르겠지만 가장 많이 보이는 것이 U% << 이 항목이더군요. 그리고 CVm 항목도 있구요. 이 두개 항목은 아무리 찾아봐도 그 의미를 알 수가 없던데... 알려 주시면 참 감사하겠습니다. 아니면 전문적으로 상담받을 수 있는 담당자..

Evaluating Nonwoven Fabric Irregularity on the Basis of Linnik Functionals

New statistical characteristics are suggested for analyzing nonwoven fabric irregularity. These characteristics are based on the concept of outliers of random field irregularity beyond (or beneath) a fixed level, and allow the area and volume of these outliers to be determined. Outlier statistics are studied and results are presented for ..

Structure-Property Relationship of Blended Cotton Yarns Made from Low and High Tenacity Fibers

The tensile response of staple yams is usually determined by their structure and the mechanical properties of their constituent fibers. Yarn structure is influenced by the radial disposition of fibers along the yam length, commonly known as migration, and the packing density of the fibers in the yarn cross section. These, in turn, are aff..

Cuticle Scale Heights of Wool and Specialty Fibers and Their Changes Due to Textile Processing

Animal fiber identification in the scanning electron microscope (SEM) using the criterion of cuticle scale edge height (CSH) is a well established method suitable for all stages of textile processing. In his paper, P. A. Tucker ( Textile Res. J. 68, 229-230 (1998)) presents results that lead him to state comprehensively, "fiber identifica..

Objective Evaluation of Fabric Hand Part I: Relationships of Fabric Hand by the Extraction Method and Related Physical and Surface Properties

A simple extraction method effectively measures the changes in hand resulting from different fabric types, flame retardant (FR) finishes, and fabric wetness. The effects of FR finishes and wetness on the original fabric hand are inconsistent in terms of the direction of increase or decrease depending on the fabric and finish. When FR fini..

Air Flow Through Textiles at High Differential Pressures

Air flow through fabrics at relatively high differential pressures is studied both ex perimentally and theoretically. An extension of a previous model for fluid flow through a bed of fibers takes into account the geometric irregularities and deflection of the fibers, successfully predicting that the pressure drop across the fabric is a li..

A Three-Dimensional Analysis of Specular Reflection from Single-Jersey Knitted Fabrics

This paper presents a mathematical model for calculating specular reflection of sin gle- jersey knitted fabrics using a three-dimensional analysis. A computer simulation program based on the model is developed to generate goniophotometric curves using Cartesian coordinates and Euler angles derived from the geometry of a knitted loop. Two ..

Tensile and Uniaxial Fatigue Behavior of Poly (p-Phenylene-co-3,4'- Oxydiphenylene Terephthalamide) Fibers: Relationship with Chain Orientation

This paper investigates the physical properties of poly(p-phenylene-co-3,4'-oxy diphenylene terephthalamide) [PpPOT] fibers in comparison with poly (p-phenylene terephthalamide ) (PPTA) fibers. With regard to tensile responses, the two fibers show nearly the same elastic deformation with significant modulus increase during extension. Howe..
