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 […]

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 […]

Determination of Sliver Count and Count variation by Measuring Drum
Determination of Sliver 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 […]
Determination of Carpet Thickness by Shirley Thickness Tester
Determination of Carpet Thickness by Shirley Thickness Tester Introduction: Carpet is a floor-covering textile having surface formed from yarns or fibres projecting from a substrate. Fabric thickness is a parameter of fabric which involves handle, creasing, wrinkle resistance, thermal resistance and other fabric properties. A carpet is compressible and therefore it is necessary to specify […]
Fabric Abration Resistance by Abration Resistance Tester
Fabric Abration Resistance by Abration Resistance Tester Introduction: Abrasion is just one aspect of wear and is the rubbing away of the component fibres and yarns of the fabric. It is a series of repeated applications of stress; therefore a capacity to absorb punishment is required to the fibres. Inherent fibre properties such as work […]
