Determination Of Fabrics Abrasion Resistance

Determination of resistance of any fabric to abrasion is usually carried out by abrading the fabric under specified conditions against a standard abrading. Although plane abrasion of fabric surface does not cover all aspects of strains that are important in determining service life, there are occasions when such a test gives useful information. Martindale TESTER With 4 nos circular abrasion tables circular specimen of fabric are abraded under known pressure under a motion which is the resultant of too simple harmonic motion at right angle to each other the resistance of abrasion is estimated by visual appearance or by finding the loss in mass of the specimen.The test gives a score in 1,000′s of „cycles‟ or „rubs‟. Domestic fabrics often have a rating of 20,000 rubs. Generally, the higher the Martindale Score the more suitable the fabric for heavy usage. The unique design of our Martindale abrasion tester allows removal of individual sample holders for examination without lif...

The Purpose Of Glow Wire Testing

Glow wire testing is an electrical safety test designed to evaluate the flame resistant properties of plastic materials used in electrical devices. Its purpose is to protect against the risk of fire from overheated or electrically energised parts which may cause the plastic material to ignite. This may occur in normal use, under reasonable abnormal use, malfunction or failure of the product. The glow wire simulates an over-heated part which then comes into contact with plastic materials. The purpose of glow wire testing is to protect against the risk of fire from overheated or electrically energised parts which may cause the plastic material to ignite.this test is mainly for products sold in the European market, as the IEC is based in Europe (Geneva, Switzerland) rather than the United States. The glow wire testing we mentioned is actually made up of three tests in the IEC60335 standard (GWIT, GWFI, GWT), which are somewhat similar, but not the same. Therefore, GWT is a bi...

How To Test Washing Color Fastness?

Wash color fastness tester can be used for washing, dry cleaning test. Dual cylinder separation, equipped with separate operation control panel, can carry out two different temperature experiments at the same time. Electronic light touch switch, LCD menu display, no mechanical contact, safe and reliable. The test frame drive is stable and reliable in exchange for washing cup. Equipped with 500ml and 1200ml water washing cups, each cylinder contains 24 cup slots (12 different sizes) to meet different test requirements. The heating pipe has no noise, long life and accurate temperature control. Wash fastness test steps: First, sample, size of 40 mm x 100 mm, affixed lining fabric is the same as the sample size, can two pieces is the single fiber affixed lining fabric or a fiber lining fabric, and sample along the short edge stitching, form a composite sample. Second, Dual cylinder Wash color fastness test instrument : diameter of 75 mm and 125 mm high airtight container, sealed cont...
