Vertical Flammability Tester Flammability of fabrics may be determined by igniting one end of fabric under test by mean of a suitable burner having a specified flame intensity and determining the extend of propagation of flame and the time taken by the flame to propagate between two marked levels. In the vertical strip flammability tester, a test specimen cut from the fabric under test is suspended vertically inside an enclosure and the flame from a Bunsen burner is applied at its bottom edge. The time taken by the flame to propagate between two specified marks is then determined from which the numerical rating of flame resistance property found. This method is suitable for all fabrics which are in form of sheets or can be converted by cutting into sheets. Flammability Tester for fabrics consists of a vertical sheet metal cabinet closed on three sides and top and bottom. The front side is kept open for insertion of the test specimen. The test specimen is suspended from a clip such that it hangs freely in the center of the cabinet. Two marker wires are fixed behind the fabric under test such that they are located 28 cm and 155 cm below the clip. A removable auxiliary clip is also provided to enable shorter specimens of flame resistant fabrics to be tested. A bunsen burner of 9.5 mm diameter opening is placed in the lower half of the cabinet and can be moved on two guide rods to enable it to be brought vertically below the free end of the test specimen. A flexible pipe line with a needle valve is provided to control the flame height. TECHNICAL DATA Size of Test Specimen 183 cm x 4 cm Size of modified test specimen 40 cm x 4 cm Distance of upper marker wire from the main clip 28 cm Distance of lower marker wire from the main clip 155 cm Distance of lower marker wire from the auxiliary clip 10 cm Diameter of burner opening 9.5 mm Dimensions of the Cabinet 35 cm x 40 cm x 205 cm

Spray Rating Tester To determine the surface wetting resistance of fabrics. Comprising a metal framework allowing distilled water to be sprayed through a nozzle onto a test specimen at 45° and 150mm below the nozzle. The appearance of the specimen is compared against an optional photographic scale. Parameters: a) Glass funnel: φ150 × 150mm (volume approximately 500 ml) b) Sample press release angle: 45 ° c) Sample clip diameter: φ150mm d) Nozzle head to the sample center distance: 150mm e) Dimensions: 500 × 400 × 500mm (L × W × H) f) Standards：GB/T4745-1997；ISO4902 The Spray Test is a simple method to determine the resistance of any fabric, which may or may nothave been given a water-resistant or water-repellent finish, to surface wetting by water.

Rotawash Washing Fastness Tester is used for determining colour fastness of textile materials to washings. This is attained by mechanically agitating a specimen of textile in contact with pieces of specified adjacent fabrics in a soap – soda solution. Before being rinsing and dried. The change in colour of specimen and stains of the adjacent fabrics are assessed with standard Grey Scale. WASHING FASTNESS TESTER’ consists of a thermostatically controlled, electrically heated water bath made of Stainless Steel. The bath is heated by means of immersion heaters and its temperature controlled by a capillary type thermostat. The temperature of water inside the bath is displayed on a digital temperature indicator. The bath has a double walled hinged lid made of stainless steel sheets. The jars in which the test solution and the test specimens are kept during the test are made from stainless steel and are provided with rubber scales for water tight closing. They are held in a cast stainless steel rotor assembly mounted on a stainless steel shaft at the center of the bath and rotating about a horizontal axis with the help of a geared Motor. A clockwork timer is provided to stop the motor after a pre-determined time. The apparatus is fabricated on a sturdy angle iron frame and is completely enclosed on all four sides with mild steel sheet duly enameled in metallic green paint. The top of the apparatus is covered with stainless steel sheet. One hundred stainless steel balls of 6 mm diameter are supplied with the apparatus as standard accessory for providing beating action during the washing operation. Extra stainless steel balls and standard Grey Scales are available as optional accessory. TECHNICAL DATA : Number of Jars Eight Volume of each Jar 550 cc (Approx) Distance of base jars from the axis of rotation 50 mm Speed of rotation 40 to 45 rpm. Temperature of Water Bath Ambient of 980 C Motor ¼ HP 230 V AC. RELATED STANDARDS : IS 687 – 1979, 764 - 1979, 765 – 1979, 3417 – 179, 3417 – 179, Method of determination of Colour fastness of textile materials to washing : Test1, Test2, Test 3, Test 4 and Test 5 respectively.

Air Permeability Tester For textile consists of an arrangement for holding the test specimen between two flat faces so as to expose a known area to the flow of air through it, a vacuum system to draw air through the exposed of the test specimens, arrangement to measure the volume of air flowing through the test specimen, and arrangement to measure the pressure drop between the two faces of the test specimen, The test specimen is hold between two round shaped grips. The grips are lined with rubber gasket to avoid the leakage of air through the edge. The two grips can be held the test specimen with the help of a hand spirited can mechanism. The vacuum needed to draw the air through the test specimen is created with the vacuum pump supplied with the instrument. The vacuum pressure is measured by the manometer tube terms of mm of water level & airflow is measured by the rotameters supplied with the instrument. RELATED STANDARDS : IS 11056 – 1984 : Method for determination of Air Permeability of fabrics. DIN 55887 : Testing of fabrics Determination & the Air Permeability of fabrics.
