Fibre Content / Composition Test
Fibre Content / Composition Test Analysis of fibre content: Qualitative analysis Quantitative analysis (for blended material) Qualitative analysis By Flame/burn test By solubility test Reaction of Fibres to Flame Solubility of Fibres (Method-AATCC 20-2000) S=Soluble I=Insoluble P=Plastic mass formed S/P=Soluble/Plastic mass formed N=Nylon 6 is soluble but Nylon 6/6 is insoluble Quantitative analysis of different […]
Crease Resistance & Recovery Test
Crease Resistance & Recovery Test Crease: This is a fabric defect evidenced by a break line or mark or fold in a fabric generally caused by a sharp fold. Crease appears when the fabric is distorted in such a manner that part of it is stretched beyond its elastic recovery. During creasing the upper surface […]

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 […]
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) , […]
