Thermal Properties of Polymers In the amorphous region of the polymer, at lower temperature, the molecules of the polymer are in, say, frozen state, where the molecules can vibrate slightly but are not able to move significantly. This state is referred as the glassy state. In this state, the polymer is brittle, hard and rigid […]

Identification of Textile Fibre
Identification of Textile Fibre A: Burning Test :- Textile fibres can be identified by observing the burning phase of these fibres in flame . All natural and regenerated fibres are burnt to ash and special smell is observed for each fibre. Synthetic fibres on burning contract and form beads. All cellulosic fibres such as jute, […]
An Overview of the Spinning Properties
An Overview of the Spinning Properties Researchers from the textile industry of many countries have worked on the project to develop the nature of the spin produced by various natural sources. Engineer A.A. under the drafting of the spinning properties The study of sinyin has been the subject of the study and proposes to propose […]
Mechanical Properties of Polymers
Mechanical Properties of Polymers Mechanical Properties: It is of great importance to be familiar with some basic mechanical properties of the material before its application in any field, such as how much it can be stretched, how much it can be bent, how hard or soft it is, how it behaves on the application of […]
Modern Techniques of Weft Insertion in Projectile Weaving Machine
Modern Techniques of Weft Insertion in Projectile Weaving Machine Conventional Weft insertion in Projectile weaving machine :- To understand the modern techniques of weft insertion in projectile weaving machine first let’s see the weft insertion in conventional projectile machine. In conventional Projectile weaving machine a projectile (fig.1) is used to hold or grip the weft […]
Chenille Fibre | Advantages & Disadvantages of Chenille Fibres
Chenille Fibre: Chenille may refer to either a type of yarn or fabric made from it. Chenille is the French word for caterpillar whose fur the yarn is supposed to resemble. The chenille yarn is manufactured by placing short lengths of yarn, called the “pile”, between two “core yarns” and then twisting the yarn together. […]
Thermal Properties of Polymers

Degumming of Silk
Degumming of Silk Objective : Degumming or boiling-off is the process employed to remove the silk gum (sericin) enveloping the two raw silk threads (fibrion) . During the spinning process of silk by silkworms the two filaments are made into one by means of proteinious gummy substance called sericin. The gum content of silk […]
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 […]
