what is Seam Fatigue Tester

The Seam Fatigue Tester from Qinsun lab is a two station bench top machine, used for evaluating fabric or leather seating materials resistance to tearing or needle hole elongation of a sewn seam. Each station includes a pair of suitable clamps for attaching the test sample.

The seam fatigue tester is designed to evaluate the fatigue resistance of seam on the material which is applied on the surface of automotive seat. The surface material of car seat (leather, synthetic leather, fabric, etc.) is often stitched together. The stitching strength of the material seam and the fatigue strength of the seam can directly affect the service life of the seat. The strength and life of the joint of the test material can effectively predict the life of the seat and provide the direction of improving the service life.


The operator installs the set up gage between one pair of sample clamps on a station. The sewn test sample is aligned and clamped into position.The set up gage is removed and installed on the second station. The second sample is aligned and clamped into position and the set up gage is removed. The desired number of test cycles is entered on the cycle counter and the test is started. Once this cycle count is reached the machine will automatically stop. Test samples are visually evaluated.

Tinuvin 1130: An Excellent UV Absorber

 In the field of the chemical industry, UV absorbers play a crucial role, particularly in protecting materials from UV damage. Today, we will delve into a highly regarded UV absorber—Tinuvin 1130. Tinuvin 1130 : chemical name: 3-(3-(2H-benzotriazole-2-yl)-4-hydroxy-5-tert-butyl phenyl)propionic acid polyethylene glycol 300 ester; CAS login number: 104810-48-2. This product is an exceptional UV absorber that offers numerous benefits due to its unique properties. One of the standout features of Tinuvin 1130 is its excellent weather resistance. It has a strong ability to absorb ultraviolet rays, particularly those with wavelengths ranging from 290-400nm. This effectively prevents coatings, plastics, rubber, and other materials from being damaged by UV rays, thereby maintaining the performance and appearance stability of these materials and extending their service life. In addition, Tinuvin 1130 exhibits good compatibility. It is easy to emulsify in water-based systems and can be...

Air-cooled Xenon Lamp Aging Tester

  The air-cooled xenon lamp aging tester is a device that uses an air-cooled system to dissipate heat and a xenon lamp to simulate ultraviolet light, visible light and infrared light in natural sunlight to perform accelerated aging tests on materials. It is commonly used in industries such as automobiles, coatings, plastics, rubber, and textiles. It can evaluate the aging resistance of materials under the combined effects of long-term light, temperature, humidity and other environmental factors in a relatively short period of time, helping companies improve product quality, extend service life, and optimize product anti-aging formulas and processes. Structural composition:  The main body is a test chamber, equipped with a xenon lamp and a matching optical filter system to simulate sunlight of different wavelengths, as well as temperature, humidity, lighting time and other control and adjustment devices, as well as an observation window and a sample rack. Working principle: The...

The Structure of Hexapod Tumble Tester

The Hexapod Tumbler Tester is a popular apparatus used in the evaluation of the appearance retention of carpets. Drum – constructed of Nylon or other like material and capped by a lid that is secured by a latching device. The drum and lid have a locating groove to hold the specimen backing sheet flat to the inner wall of the drum. A photograph of a typical drum is show in Photograph 1 and Photograph 2. The drum dimensions are:   Internal Diameter: 12 ± 0.18 in. (302 ± 5mm) Wall Thickness :0.3 in. approx. (8 mm approx.) Internal Depth: 8.2 ± 0.2 in. (207 ± 5 mm)  Driving System - cradles the drum on rollers and keeps the axis of the drum level, and rotates the drum at 35 ± 2 rpm (3.6 ± 0.2 rad/s). The driving direction reverses after approximately 500 revolutions.  After the 500 rotations the unit will stop and stand stationary for approximately 5 to 15 seconds, then begin rotating in the opposite direction. After 2000 rotations the unit will stop and w...
