Crumple / Flex Tester TF117C
CrumpleFlex Tester, to determine the degradation of water resistance of coated fabrics due to crumpling and Flexing in use.
Crumple / Flex Tester, by this instrument user can test the degradation of water resistance of coated textiles due to flexing and crumpling in daily application use.
The equipment tests a tube of fabric by twisting it through 90o stretching alternately compressing the tube at the same time. After completion of the test, the fabric is tested for resistance to penetration by water. Crumple-Flex Tester is fitted with electronic pre-determined counter with automatic stop at a pre-determined number of cycles, and also fitted with acrylic plastic interlock safety cover.

What is Flexing Resistance
Flexing Resistance is a measure index of bending resistance of rubber, leather and coated fabric. Take coated fabric as an example, the fabric will be distorted countless times in the process of using and washing, which requires a certain degree of flexing resistance to ensure that the fabric will not be wrinkled or damaged in a certain amount of time. Therefore, folding fastness is an important index of fabric. The fabric is twisted back and forth on a specified test instrument, recording the number of distortions and observing the damage conditions of the coated fabric.
CrumpleFlex Test Method
Principle: stitch a rectangular coated fabric sample into a cylindrical shape, and fix it between two disks. One of the disks wobbles about 90° around its axis and the other moves back and forth along its axis, which distorts and compresses the sample at the same time until the sample has completed a certain number of back and forth bending or has obvious damage.
Sample preparation : Cut a piece of sample along the horizontal and longitudinal direction of the fabric. Each sample is 220mm long and 190mm wide, then stitch the sample into a cylinder with 190mm length and 64mm inside diameter and the coating is outward.
Test procedure: check whether the equipment is running at the required speed before testing, install the cylindrical sample between two disks, each end of the sample is close to the inner side of the disc and clamp it tightly. The oscillating disc should stop at the center of the pendulum wheel, and the suture line of the specimen should be in line with the midpoint of the oscillating disc when we installing the sample. Start the instrument and run to the specified number of times.
Sample inspection: After the test, record the number of flexing, observe the whole appearance of the sample, and evaluate the damage degree of the sample. By comparing the samples with flexing test and without flexing test, record the details of wrinkle, fading and so on of the samples.
