Determination of GSM of Woven and Knitted Fabrics Introduction : The GSM of fabric is one kind of specification of fabric which is very important for a textile engineer for understanding and production of fabric. ‘GSM’ means ‘Gram per square meter’ that is the weight of fabric in gram per one square meter. By this […]

Determination of Warp and Weft Crimp Percentage of a Fabric
Determination of Warp and Weft Crimp Percentage of a Fabric Introduction : Percentage of crimp is defined as the mean difference between the straightened thread length and the distance between the ends of thread while in the cloth, expressed as percentage. When warp and weft yarns interlace in fabric they follow a wavy or corrugated […]
Determination of Twist Per Inch (T.P.I) of Jute Yarn by Ordinary Twist Tester
Determination of Twist Per Inch (T.P.I) of Jute Yarn by Ordinary Twist Tester Theory: “Twist is the measure of the spiral turns given to a yarn in order to hold the constituent fibres or threads together”. (Shinkle) “Twist is the spiral disposition of the component of a yarn, which is result of relative rotation of the […]
Determination of Fibre Composition in a Given Sample (Blended Material)
Determination of Fibre Composition in a Given Sample (Blended Material) Object : To find out the amount of different fibres in the sample. Theory: To determine the composition of different fibres in a blended fabric we have to apply chemical test. Because there may consist of both thermoplastic and non-thermoplastic fibres. So we cannot different […]
Determination of Twist Per Inch (T.P.I) of Cotton Yarn by Ordinary Twist Tester
Determination of Twist Per Inch (T.P.I) of Cotton Yarn by Ordinary Twist Tester Theory: “Twist is the measure of the spiral turns given to a yarn in order to hold the constituent fibres or threads together”. (Shinkle) “Twist is the spiral disposition of the component of a yarn, which is result of relative rotation of the […]
Identification of Given Textile Fibre Sample
Identification of Given Textile Fibre Sample Object: To know about the physical properties of sample. To know about the chemical properties of sample. To identify the type of sample fibre. Atmospheric condition: Wet condition: – 26 ° c. & Dry condition: – 30° c. Difference between wet and dry bulb = 30° c-26 ° c. […]
Determination of Water Repellency by Spray Tester
Determination of Water Repellency by Spray Tester Introduction: The merit of a fabric intended for rainwear, wagon covers or tents is judged, amongst other properties, by its ability to keep water out; conversely, when intended for hose pipes or canvas buckets, to keep water in. In another direction, some fabrics must exhibit the ability to […]
Determination of Roving Count and Count Variation by Measuring Drum
Determination of Roving Count and Count Variation by Measuring Drum Theory: – Yarn count: The count of a yarn is a numerical expression which defines its fineness. It means, by yarn count we come to learn about the thinness or thickness of a fibre or yarn. The count of the yarn is the number of […]
