SHEAR DEFORMATION AND TEST METHODS OF FABRICS

Abstract

Shear behaviour is one of the most important properties that make fabrics unique among paper or plastic products. Shear deformation is an important parameter that defines the handle, pliability and drape of the fabrics. On the other hand, shear rigidity influences the strength and bending properties of woven fabrics. In this article the terms about shear deformation are explained, assumptions and models are summarised, shear deformation testing devices and their principles are examined. The advantages and disadvantages of the test methods are also considered and compared.

Keywords

• Fabric shear deformation
• shear rigidity
• shear test
• shear angle

KUMAŞLARIN KAYMA DEFORMASYONU VE ÖLÇÜM YÖNTEMLERİ

Abstract

Kayma davranışı, tekstil ürünlerini plastik ve kâğıt gibi yüzeylerden ayıran en önemli özelliklerden biridir. Kayma deformasyonu, kumaşların dökümlülük, katlanabilirlik ve tutumunu etkileyen önemli bir para-metredir. Bunun yanı sıra kayma direnci, dokuma kumaşların eğilme ve mukavemet özelliklerini etkilemekte-dir. Bu çalışmada kayma deformasyonuna ilişkin kavramlar açıklanmış, kabuller ve modeller özetlenmiş, kay-ma deformasyonu ölçüm yöntemleri ve prensipleri kapsamlı bir şekilde incelenmiştir. Ölçüm yöntemlerinin avantajları ve dezavantajları ele alınarak yöntemler karşılaştırılmıştır.

Keywords
