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.

Part 1: Optical Properties of Textile Fibers Part 2: Birefringence | Fiber Birefringence Part 3: Reflection and Luster Optical Properties of Textile Fibers Optical Properties When light falls on a fiber, it may be partly transmitted, absorbed or reflected, depending on the structure of the light. The transmission, reflection and absorption of light determine the […]
Physical Properties of Polymers
Physical Properties of Polymers Polymer: A chemical compound or mixture of compounds formed by polymerization and consisting essentially of repeating structural units is called ‘Polymer’. Polymers range from familiar synthetic plastic such as polystyrene to natural bio-polymers such as DNA and proteins that are fundamental to biological structure and function. Physical Properties: Physical properties of polymers […]
Fabric Tearing Strength Test
Fabric Tearing Strength Test Tearing strength: A fabric tears when it is snagged by a sharp object and the immediate small puncher is converted into long rip by what may be a very small extra effort. It is probably the most common type of strength failure of fabrics in use. It is particularly important in […]

What changes does the Crockmeter bring to our lives?
What changes does the Crockmeter bring to our lives? The Crockmeter is used to determine the colorfastness of the textiles to wet or dry rubbing. You can use the Crockmeter for the Crockmeter test and the Crockmeter price is also competitive. A pre-determined electronic counter is fitted in the Crockmeter for strokes of up to […]
Fabric Inspection | Four Point System
Fabric Inspection | Four Point System Inspection: The essential process of maintaining the quality of raw materials used during making the finished product is called inspection. For garments, need to check the quality of fabric, sewing thread, trims etc. The process is done following a specific SOP to check the specific items. Four-Point System: Most […]
