Do Fabric Shrinkage Testing With whirlpool Tester

   Shrinkage rate refers to the percentage that fabrics’ size presents shrink when washed or soaked, which is also an indicator of measuring the degree of fabric shrinkage. The level of fabric shrinkage rate is one of the criteria to measure product quality.         Fabric shrinkage can cause problems in two main areas: garment manufacturing and subsequent laundering by the ultimate customer. in order to make sure the product quality , the shrinkage test is necessary for each textile manufacturer.   The general procedures for preparing and marking out of samples are given in the British Standard. For critical work the recommended sample size is 500mm X 500mm and for routine work a minimum sample size of 300mm X 300mm is considered as sufficient. The samples are marked with three sets of marks in each direction, a minimum of 350mm apart and at least 50mm from all edges as shown in Figure. In the case of the smaller sample the marks are made...

Hydrostatic Head Tester For Medical MaskTesting

    Textile Test Instrument Manufacturer -Qinsunlab :   Hydrostatic Head Tester is designed to determine the waterproof property of outdoor wears, umbrella, and waterproof fabric. It is also used to test the resistance of permeability of synthetic blood for materials used in protective clothing.     Hydrostatic head or sometimes just is an outdoor industry standard way of measuring how much force it takes to force water through a piece of fabric.     The way that it is measured is by clamping a piece of fabric over the bottom of the tube and slowly filling the tube with water.    The hydrostatic head measurement just refers to how high the water got up to tube before it forced its way through the material.    An example would be a tent for summer use with a hydrostatic head measurement of 1000 mm. This means that the water in the tube got to 1000 mm high before it pushed its way through the fabric. ...

Air Permeability Tester For Textile Laboratory Testing

       The air permeability of a fabric is a measure of how well it allows the passage of air through it. The ease or otherwise of passage of air is of importance for a number of fabric end uses such as industrial filters, tents, sailcloth, parachutes, raincoat materials, shirting’s, down proof fabrics and airbags.                       Most woven fabrics such as those used for apparel, domestic and light industrial application are of relatively open construction. Measuring the air permeability of such fabrics can be carried out at low pressure differences and a number of instruments are available for the purpose.      In contrast, some materials such as leather, certain types of coated fabrics, and fabrics created for operating at increased pressure levels necessitate measuring their air permeability at appropriately high pressure levels that standard instruments are not able to provi...

How Does the Weatherometer Work?

    Accelerated weathering is actually a very powerful tool for comparative purposes. Testing simultaneous multiple formula can quickly give vital information. Instead of waiting years to get the data from outdoor exposure or feedback from customers, accelerated weathering gives you the data you need in days or weeks.          Weatherometer is a laboratory device that uses high-powered light sources & water to simulate long-term outside exposure. Ultraviolet (UV) light, a wavelength of light from the sun not visible to the human eye, can cause long-term damage to paints, plastics,fabrics and concrete finishes. Water, including rainwater and ocean saltwater, can attack finishes and degrade them. The Weatherometer can create ultraviolet, indoor, or other light frequencies to test products under controlled conditions and include water spray to add further environmental effects.    Test materials are formed into panels that can be...

SCRATCH HARDNESS TESTER For Paint Coats Testing

There are many kinds of Scratch hardness tester in the market when you search this tester trough Google. It is an all-purpose tester for the scratching and cutting jobs of all kinds on paint coats and plastic surfaces. Individual cuts, parallel cuts and (after rotating the sample 90°) also cross-hatch cuts can all be made onto test plates of different thicknesses.  The Scratch hardness tester/ cross hatch adhesion tester designed by Qinsunlab is a automatic test instrument.you don't have to do anything when it works . our tester complies with PV 3952, Ford BN 108-03,BMW etc .                                   The cross hatch adhesion test instrument is suitable to test automotive interior materials, plastics, rubber, leather, coated fabrics, coated materials, compound material, paint, ink, soft metal, etc. It is widely used in the area of product quality control, newly developed product per...

Wyzenbeek Test Machine For Testing Fabric

     Wyzenbeek testing measures flat abrasion resistance and does not consider edge abrasion or other types of surface wear that may occur in actual upholstered applications.Studies have shown that Wyzenbeek test results on the same fabric can and do vary significantly from test to test.              A Wyzenbeek machine is used for this test allowing sample of the test fabric to be pulled tight in a frame and held stationary. Individual test specimens cut from the warp and weft direction are then rubbed back and forth using an approved fabric as the abradant. The number of double rub cycles achieved before two yarn breaks occur or noticeable wear is observed is recorded as the fabric’s abrasion rating.     Wyzenbeek Abrasion Tester , made of modern ergonomic design, is to determine the abrasion resistance of fabrics when rubbed against a standard abrasive or a wire mesh screen with a backward and forward motion over a ...

Brief Introduction of Digital Tearing Tester

       The standard mannual   Elemendorf Tearing Tester  consists of a frame and pedestal, mounted on a rigid base, carrying a pendulum and pointer assembly. There are two clamps to hold the test sample, a fixed one on the pedestal part of the instrument and one on the pendulum. The dimensions of the clamping surfaces are at least 25 mm wide and 15 mm deep.       The pedestal is fitted with a low friction bearing having a horizontal axis upon which the pendulum is allowed to swing. The pointer fits on the same axial spindle as the pendulum, its friction is enough to stop it at the highest point reached by the pendulum when it swings. The pointer stop is adjustable to allow the instrument zero to be set. The base of the instrument is fitted with the pendulum release and pointer stop mechanisms. The pendulum is held in the initial position and the test is started by the release mechanism. The release mechanism is designed to ...
