When the fiber absorb water they change dimentinally ( Length, Diameter, Area ). Swelling occurs in transvers direction ( width wise ) and Axial direction ( Lengthwise). It can be expressed in term of increase in Diameter, length, area and volumes. That means the dimensionally changes due to absorbing water or moisture by any fiber …

The behaviors which are shown by a textile material when it is subjected to a torsional force is called torsional property. 1. Torsional rigidity 2. Breaking twist 3. Shear modulus 1.Torsional rigidity: Torsional rigidity can be defined as the torque required against twisting is done for which torque is termed as torsional rigidity. Mathematically, torsional …
Continue reading Torsional property of a textile with its definitionThe behavior which shows by textile material during bending is called flexural property. There are mainly three properties shown after bending a textile fiber. 1. Flexural rigidity 2. Bending recovery 3. Bending modulus 1.Flexural rigidity: Flexural rigidity is the stiffness of a textile fiber. It can be defined as the couple needed to bend a …

Continue reading Tensile properties of different fibers1. CRL method ( constant rate of loading ) 2. CRE method (constant rate of elongation) 1. CRL method: The function of applied force is to extent the specimen until it eventually breaks down. Here the loading causes the elongation. By adding constant rate of water flow in a container which is attached with the …

Muslin History : Muslin fabric originated in Dhaka, a country in southern Asia (now known as Bangladesh.) Muslin was termed after Mosul, now a city in Iraq, from where the fabric was first introduced to Europe. Muslins were also widely produced in India and imported from there to Europe in the late seventeenth century. Early …
