DRK549A Fabric Tactile Tester

Instrument purpose:

Fabric feel style is not only one of the important evaluation indexes of textile comfort, but also an important factor affecting textile sales. Therefore, textile feel style measurement instrument has always been the research direction of textile science and technology. It has become an urgent need to make a quantitative evaluation of fabric feel style correctly, effectively and objectively.Based on the concept of single machine single measurement and multi index test, the system realizes the test of fabric thickness, bending, compression, friction and tension through the simulation of manual touching fabric pulling, pressing, kneading, kneading and other actions, obtains five quantitative indexes of thickness, softness, stiffness, smoothness and tightness, and objectively evaluates the comprehensive hand feel style of fabric wind.It is suitable for general fiber sheet products: clothing fabrics, home textile fabrics, nonwovens, yarns, automobile interiors, leather, paper, etc.

Test principle:

Simulate the subjective feeling process of human hands on the fabric. All the indenters used are cylindrical images simulating human fingers, with fine lines on them to simulate fingerprints.The indenter also adopts the form of one above and two below to simulate the process of human touch.The system quantifies the corresponding indexes through physical tests such as compression, bending, friction and tension of the material, obtains the surface compression thickness, softness SF, stiffness st, smoothness SM and tightness LT, and then evaluates the comprehensive style of the fabric.

1 Thickness index, the thickness of the fabric compressed by the surface.

2 In stage I, the compression modulus and compression deformation are obtained by surface compression, which are expressed as softness SF.

3 In the second stage, the maximum bending value, bending modulus and bending work are obtained from the bending test, which are expressed as stiffness St.

4 In the third stage, the average friction force, friction coefficient, friction work, etc. are obtained through friction test, and the sliding degree is SM.

5 In stage IV, tensile modulus and tensile work are obtained from tensile test, which are expressed as tightness Lt.Comprehensive evaluation of test results: the comprehensive style ch = a * SF + b * ST + C * SM + D * LT system divides each index of SF, St, SM and lt into levels 1, 2, 3, 4 and 5.The comprehensive style is the sum of the weights of softness, stiffness, smoothness and tightness. The coefficients a, B, C and D are comprehensively determined according to the purpose, type and material of the material.
