This document describes Abdullah Al Mahfuj's profile and a presentation on measuring fabric stiffness. It introduces stiffness as a fabric property related to its ability to stand without support. The Shirley stiffness tester is described as an instrument used to measure fabric stiffness by determining the bending length of a fabric sample placed on an angled platform. The document provides specifications for the Shirley stiffness tester and describes the procedure to measure the bending length of cotton fabric samples in the warp and weft directions. The results show the bending length is 2.66 cm in the warp direction and 2.51 cm in the weft direction.

- 4. INTRODUCTION Stiffness : Stiffness is a special property of fabric. It is the tendency of fabric to keep standing without any support. Stiffness is one of the most widely used parameters to judge bending rigidity and fabric handling. Fabric stiffness and handling is an important factor for the end users. The degree of fabric stiffness is related to its properties such as fiber material, yarn and fabric structure.
- 5. Stiffness tester Stiffness Tester is used to determine the stiffness of fabrics. Use For the quick and accurate measurement of fabric stiffness
- 6. instrument used in the measurement of stiffness The Shirley stiffness tester The drape meter The Heart loop test
- 7. The Shirley stiffness tester A fabric testing instrument that is used for determine the stiffness of fabrics.
- 8. Description of Shirley stiffness tester The stiffness tester is consists of a platform, having a smooth low friction, flat surface such as polished metal or plastic. The platform is supported by two side pieces made of plastic. Index lines are engraved on these side pieces, inclined at an angle of 41.50 below the plane of the platform surface. At this angle. A mirror is attached to the instrument to enable the operator to view both index lines from a convenient position. A scale is supplied with the instrument to measure the bending length and is graduated in cm.

- 11. Apparatus: 1. Stiffness Tester 2. Scissor 3. Scale Sample: Cotton woven fabric Size: 6 X 1. Atmosphere: Temperature – 25C and relative humidity – 67% Standard atmosphere: temperature – 20oC and relative humidity - 65%.
- 12. Procedure 3 samples are cut in warp and 3 in weft directions. Sample dimensions are 6inx1in. One by one, these samples are put on the tester and a scale is put on the fabric. Then sample is moved with slab and measure the angle and a mark is made in one side of the sample. Then 6 values of each sample is used in calculating their mean value.

- 16. Result The bending length of the fabric in warp way is 2.66 . The bending length of the fabric in weft way is 2.51 .
- 17. Conclusion If the bending length of the fabric is more than fabric stiffness is more and if less stiffness is less.
