ASTM D3786 Standard Test Method for Hydraulic Bursting Strength of Textile Fabrics

This test method describes the measurement of the resistance of textile  fabrics to bursting using the hydraulic diaphragm bursting tester .This test method is generally applicable to a   wide variety of textile products . Principle; S ample is clamped over an expandable diaphragm. T he diaphragm is expanded by fluid pressure to the point of specimen rupture. The difference between the total pressure required to rupture the  specimen and the pressure  required to inflate the diaphragm is reported as the bursting strength . Significance and use: This method for the determination of diaphragm bursting strength of knitted, non-woven  and woven fabrics is being used by the textile industry for the evaluation of a wide variety of end uses. In   cases   where   test   results   obtained   using   the   procedures   in   Test   Method   D3786   have   not   been   correlated   with   actual   performance,   Test   Method   D3786   is   considered   satisfactory   for   acc

Feature of Gravel Impact Tester

The gravel impact tester is assembled by standard component and equipped with easy handling accessories, achieving gravel impact against all the main standard automotive materials on this one machine. It is the only instrument in China that adopts the universal adjustment device, and the 0-180 impact angle can be adjusted arbitrarily.( the so-called mufti-functional instruments produced by other manufacturers is actually equipped with different angel collision boxes ). The first disadvantage is that customers need constantly change collision boxes with different angles. It has a lot of trouble to make replacement and the collision boxes of different angles will cover a large area. The second disadvantage is that the collision boxes are not complete enough with different angles to meet customers need for subsequently adding the required impact angles. Impact window of the test bench:300*300 mm,(impact window size of the test bench is larger than the size produced by other manufa

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 wait for the op

Application of RCA Abrasion Wear Tester

RCA Abrasion Wear Tester is used to test surfaces for resistance to abrasion and wear. Typically used on painted or plated organic finishes, foil, and inked key pad lettering. This tester is widely used as a standard for many silicone key pad and membrane switch manufacturers. This abrader is used as a standard to the auto, appliance, cell phone, plastics, and coating industries. It uses an inexpensive roll of throw away abrasion paper. All build-up error is eliminated and consistent readings are easily obtained. The RCA Abrasion Wear Tester is also referred to as an Abrasive Wear Tester, an Abrader, a Paper Wear Tester, etc. The Norman Tool official model identifier for this machine is the 7-IBB-CC RCA Wear Tester. Easy set-up and operation Automatic shut-off Repeatable and consistent results 3 load settings Abrasion Debris does not affect test Continuously uses inexpensive unused abrasive media RCA tape abrasion test machine for mobile phone, PDA, MP3, CD player

The Physical Structure and Specification of Textiles Fabric Surface Flammability Tester

The Surface Flammability Tester is used to detect the burning behaviour of wool or fur fabric. The flame spreads quickly on the surface of the fabric, but the base cloth of the fabric does not burn.The mobile butane burner moves laterally on the surface of the fabric to see if there is a surface flame and record the damage to the base cloth.

Test Principle Of Hydrostatic Head Test

Hydrostatic head test for the Textiles test in the textile industry is very extensive, but also a certain degree of resistance to hydrostatic pressure requirements is need for some special fabrics  , so the static water pressure test is necessary. What is the main test principle of this type of experiment?  let us explain briefly.The Hydrostatic head Tester is the best Hydrostatic head test machine. The so-called waterproof and moisture (water repellent), is to make the water at low water pressure does not wet the fabric, but the body sweat in the form of water vapor through the fabric conduction to the outside world, water vapor is not between the body surface and fabric aggregation, Do not feel "boring" phenomenon. Fabric after water repellent finishing, finishing agent to change the fiber surface properties, so that the fiber surface of the hydrophilic to hydrophobic, the fabric is not easy to be wet and still breathable, and soft to the touch. Textile washing, fabr

Test Operation of Weather Ometer

  Xenon Test Chamber for color fastness test color fastness and weather fastness test, can also be used for paint, paint, paint, rubber, plastic and paper and other materials, light fastness test And light aging test. The use of argon arc lamp simulation to control the best natural weather and sunlight and other experimental conditions to test the color and performance of textile dyes can also test the aging resistance of the material, to ensure good reproducibility and reproducibility on the basis of accurate prediction Product life. weather ometer Test operation: The operation of the Atlas xenon lamp chamber is extremely simple. Specially designed sample racks make sample fixation and evaluation very simple. Programming more intuitive, all models of equipment are fully automatic, in the case of unregulated 24 hours a day, 7 days a week continuous operation. Sample installation: The test sample in the Atlas test chamber is fixed on an approximately horizontal plane. This
