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 […]
Carbon Fibre | Properties of Carbon Fibre
Carbon Fibre | History of Carbon Fibre | Properties of Carbon Fibre | Production Process of Carbon Fibre Carbon Fibre: Carbon fibre shortly CF are fibres that have at least 90% of carbon in their mass. They are produced from carbonization of organic fibres. There are 3 different types of CF: Graphite fibres hold […]
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 […]
Light Fastness and Factors Influencing Light Fastness Behavior
Light Fastness and Factors Influencing Light Fastness Behavior Textile Dyes and Pigments used in the industry vary to a great extent in terms of their resistance to light sources and this phenomenon is called as ‘Light-fastness of Textiles’. Sunlight materials emits electromagnetic radiations of several wavelengths. Visible range of spectrum (400 – 700 nm) , […]
Thread Numbering System
Thread Numbering System Sewing Thread: Sewing thread is an essential element of garments. Sewing threads are special kinds of multi-layer yarn that are engineered and designed to pass through a sewing machine rapidly. It can be made out of many different materials including cotton, linen, nylon, and silk etc. According to Oxford Dictionary, “A thread […]
Textile Testing : Pilling Test of Fabric
Pilling Test of Fabric | Pilling Phenomena Pilling: Pilling is formation of little balls of fibers (pills) on the surface of a fabric which is caused by abrasion in wear. Pilling is the tendency of fibers to come loose from a fabric surface and form balled particles of fiber. Causes of Pilling: Due to wear and […]
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. […]
Lap Preparation in Combing | Sliver Lap Machine | Ribbon Lap Machine
Lap preparation is the process to prepare for combing process by making flat laps with combining multiple threads of carded slivers. It is the important step in the combing process, which influences the quality of the combed sliver.
Basic Concept of Combing Process | Types of Comber Machine
Combing is the process that removes the final proportion of short fibers, neps and others impurities such as vegetable matter and seed coat fragments in cotton that has already been carded. Combed yarns are superior in quality when compared to carded yarn as they are generally finer, stronger, smoother and more uniform due to the removal of short fibers and the alignment of fibers.
