   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...

    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. ...

       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...
