Testile Testing Equipment

Air permeability is an important factor in the performance of such textile materials as gas filters, fabrics for air bags, clothing, mosquito netting, parachutes, sails, tentage, and vacuum cleaners. In filtration, for example, efficiency is directly related to air permeability. Air permeability also can be used to provide an indication of the breathability of weather-resistant and rainproof fabrics, or of coated fabrics in general, and to detect changes during the manufacturing process. Air Permeability Testing Apparatus accurately and swiftly determines the resistance of fabrics (woven, knitted and nonwoven textile) to the passage of air (air flow) under constant pre-set air pressure while firmly clamped in the test rig of selected test head/area. The air permeability of the fabric is calculated automatically within a short time. Air Permeability  Test Procedure 1 Test the conditioned specimens in the standard atmosphere for testing textiles, which is 21 +/- 1°C...

 The color fastness to gas fume tester is equipped with a Bunsen burner and rotating rack. As the testing occurs over an extended time in an unobserved environment, a number of mechanisums have been incorporated to insure the safety of the operator including gas pressure regulation, unburnt gas detectors, extinguished flame alarm, and an interlocked flame ignition system . Gas Fume Chamber , to determine the burnt gas fume color fastness of textiles when exposed to atmospheric oxides of nitrogen derived from the combustion of gases.A specimen of the textile and the test control fabric are exposed simultaneously to oxides of nitrogen from burnt gas fumes until the control shows a change in color corresponding to that of the standard of fading. The change in color of the specimen is assessed with the standard gray scale for assessing change in color. Textile samples and control samples are placed in the gas smoke at the same time until the color of the control sample changes t...

The wrinkle recovery test instrument detects the recovery of the specimen after a certain period of time under a load. It is suitable for any fiber pure or blended fabric test. Besides, it can not maintain the shape of stable materials under the characteristics of the conditions, such as the material which is soft, thin and easy to bend.  We can evaluate its anti-crease performance through this device. The wrinkle recovery tester is used  to determine a fabric's ability to recover after wrinkling under a predetermined load for a set period of time. Set of 3-D plastic replicas are available to grade fabrics. The instrument consists of a base with a bracket, the base of the fixed steel plate and the top of the movable steel plate to match ,the activities of the flange with the locking pin. Equipped with four standard weights, respectively, 2000g, 1000g, 500kg, 200kg. The main principle of the wrinkle recovery tester is to apply a predetermined pressure to the spe...

Ink abrasion tester simulates a similar environment to test the rub resistance on printed materials.It is used to analyze the life of label by creating actual environment of application to evaluate abrasion resistance of surface coating layer of printed material. inks rub resistance tester simulates the actual working environment of product and helps to identify the quality and printing method to be used for printing of label based on application of product and its working environment. Ink abrasion test, also known as Ink Rub test, is to measure the ink resistance against rubbing on packaging materials, professionally designed for abrasion resistance of surface coating layers of printed materials, e.g. ink layer or photosensitive (PS) coating. This instrument could effectively analyze the problems of poor abrasion resistance, ink layer falling off, lower printable force and poor hardness of coating layers of printed materials. The tests are performed according to the following ...

Automatic Digital Direct Residual Shear Machine is used to determine the resistance to shearing of all types of soil specimens both consolidated and drained, undisturbed or remoulded samples. The Automatic Direct / Residual Shear Apparatus can accommodate specimens dia. 50, 60, 100 mm, and square 60x60, 100x100 mm. The Automatic Direct / Residual Shear Test Machine is equipped with a control closed loop motor with epicycloid reducers. At the beginning of each test, the machine performs an automatic and complete internal check, a position reset with the elimination of all possible positioning errors and all pauses. The input of all the test patterns is achieved by the interaction of the keyboard and the alphanumeric display with self-memory, thus granting infinitesimal resolutions in short times. All data are input and stored when the machine is in stand-by, without affecting the specimen under test with quick machine setting. Possibility to fix maximum excursion of the shear b...

To determine yarn twist in single or plied yarn, quadrant type with auto stop & reverse for conventional or untwist/re-twist methods. Test length adjustable up to 50 cm / 20 inches for S & Z twist yarn.It has been designed specially to meet the growing demand of the textile industry for an accurate instrument to measure the twist in the twisted yarn. The yarn twist testing machine has facility of both untwist/twist methods for measurement of TPM of twisted yarn. Different models are available. The system consists of a set of clamps, one of which rotating and the other fixed. The rotating clamp is driven by hand through a speed increasing arrangement (by the motor in the motor operated model) and a five digit resettable revolution counter (digital counter in motor operated) to count the number of twists. The fixed clamp is pivoted on jewel bearings and carries off a pendulum arm having a sliding weight to give the desired tension to the yarn. The fixed clamp assembly ca...
