Frictional Properties

Frictional Properties Friction is a vital important factor in the application of fibrous materials to engineering. Frictional property is the surface property of the fibers when two solid surfaces slide against each other. Due to fiber friction, static charge and heat energy is produced. Friction: Friction is the force of two surfaces in contact, or […]

Torsional Properties of Textile Materials

Torsional Properties of Textile Materials Torsional Property: Fibers are twisted to form yarns, while are made into textile fabrics or ropes. The torsional properties determine how fibers respond while being twisted. Torsional Rigidity: The torsional rigidity is the resistance of a fiber to twisting. In the Hookean region of small stains, the torsional rigidity defined […]

Flexural Properties of Textile Materials

Flexural Properties of Textile Materials The behavior which shows by textile material during bending is called flexural (bending) property. The importance of Flexural properties is required when we wear cloth. Significance of Bending and Twisting: ❶  The bending and twisting of fibers influence the behavior of bulked yarn and the drape and handle of fabrics. […]

Reflection and Luster

When light falls on the fiber, part of light is reflected. The luster of a single fiber is determined by the total visual appearance of these reflections from the fiber surface. It is directly proportional to the amount of light reflected by a fiber. Silk fibers has a high luster and cotton has low luster.

Swelling of fibre and Types of swelling

Dimensionally changes due to absorbing water or moisture by any fiber is known as swelling. When fiber absorbs water they change dimensionally. Swelling occurs in transversely (width wise) and axially (Lengthwise). It may be expressed in terms of the increase in diameter, area, length or volume.

Birefringence | Fiber Birefringence

The difference between the refractive index indices of the fiber in a direction at parallel to the fiber axis and in a direction at right angles to the fiber axis is called birefringence of that fiber. Birefringence is responsible for the phenomenon of double reflection.

Directional Field Effect in Wool fiber | Significance of DFE | What is DFE

DFE (Directional Field Effect) in wool fiber What is DFE ? We all know that, textile fibers have to undergo various processes before they become a part of the fabric. While undergoing these processes, the fibers are subjected to friction. This frictional force can not only be effective between the fibres & various parts of […]

Creep and Crimp of fiber

Crimp is a term to describe the waviness of a fiber. We can also describe this in terms of the force or energy required to uncrimp a fiber. It’s expressed in percentage. A crimped fiber placed on a flat plane is l0 and the length of the same fiber when the crimp is removed by applying a tension is l, then the crimp is given by …
