부직포의 기공 특성

기공의 형상은 부직포의 물리적 성질 및 역학적 성질에 영향을 미친다. 기공 형상을 자동적으로 특성화할 수 있는 방법이 제시되었다. 기공 형상은 기공 경계 함수(pore bourdary function)의 푸리어 급수(Fourier series)를 이용함으로써 특성화된다. 이에 따른 결과를 기하학적 방법을 이용하여 측정한 형상 서술자(shape descriptor)와 비교하였다. 또한 섬유 밀..

Characterizing Lateral Contraction Behavior of Spunbonded Nonwovens During Uniaxial Tensile Deformation.

Researchers investigated an experimental method based on video recording and image analysis to characterize the lateral contraction of spunbonded nonwoven fabrics during uniaxial tensile deformation. A digital clock recorded the time signatures during the experimental procedure. The time signatures corresponded to 5, 10, 20, 30, 40, 50, a..

Index 96 - Innovations in Nonwovens.

Index 1996 will be held during February 1996 in Geneva, Switzerland. The exhibition will feature the latest innovations in nonwoven fabrics for transportation, construction, packaging, medical, filtration, and protective clothing applications. Approximately 400 companies will display their products, and exhibition space will be 15 percent..

Foundation of Stitchbonding Technology.

An historical overview of stitchbonding technology illustrates the application of the process worldwide since its beginnings in 1949. In 1949, stitchbonding offered major cost advantages in spun yarn manufacturing. Today, a wide variety of nonwoven products can be developed on stitchbonding machines. Stitchbonding machines can produce fro..

The Development of Nonwoven Product for Automotive Filter Applications.

In 1970, Allied Aftermarket began research to create a nonwoven process to manufacture a new dry laid pleatable gradient density nonwoven filter material from wood pulp and textile fibers. Allied Aftermarket worked with nonwoven equipment suppliers and an outside research and development company. Researchers combined a dry forming wood pu..

New High-Speed Suction System for the Production of Spunbonded Nonwovens.

The new spun bonded system by Karl Fischer Industrieanlagen can be used to manufacture polyester, polypropylene, and nylon spun bonded fabrics. Air velocities for the high speed suction system can be as high as 15,000 metrs per minute, generating filament

Nonwovens for Artificial Leather.

Nonwoven fabrics developed for use as artificial leather are very specialized, with requirements for dimensional stability, porosity, mechanical properties, elasticity, and suppleness. These fabrics, however, must be easy to cut, sew, and glue. Nonwoven f

INDEX '96: Riview.

On February 13-16, 1996, more than 9,000 people and 391 exhibitors attended the largest INDEX on record. Exhibitors ranged from suppliers of machinery, equipment, and raw materials for nonwoven roll goods manufacturers and converters. A comprehensive review of INDEX 1996 discusses new developments in needle loonms, hydroentanglement, melt..

Nonwovens in Sanitary/Absorbent Products.

Nonwoven products in the sanitary and absorbent field, in addition to being formed from carded staple fibers with binders, are also formed as staple fibers without binders, laminates, extruded sheets, spun bonded, spun laced, melt blown, thermal bonded, and spertured fabrics. Disposable coverstock will continue to be the largest single en..
