Leading Manufacturer, Supplier & Retailer of Twist Tester, Perspirometer Tester, Crease Recovery Tester, Washing Fastness Tester and Spray Tester.
To measure the TPM/TPI of multifilament twisted yarn or 2/3 ply yarn driven by a motor to un twisted the yarn and at a final stage the remaining twist are separated by using the pin by pin separation method and the twist of the yarn is displayed digitally in terms of TPM or TPI.
For determining the resistance of the colour fastness of textile against human perspiration on dyed fabric is determine by exposing the fabric sample in alkaline and acidic reagents, while in contact with grey adjacent fabric. The test specimen along with adjacent fabric is placed between the acrylic plates under a fixed load and kept inside the incubator oven for a specified time.The apparatus use for the purpose is called Perspirometer.
To measure the Crease Recovery property of the fabric by measuring the recovery angle on a specific scale under specific weight. The crease under specified load for fix time and is then transfer to the device, where one end of the specimen is held in a spring loaded clamp and other is allowed to fall free under its own weight.
The equipment is used to determine the color Fastness of textile material perspective of any compositions for example cotton, Nylon, Linen, Silk, Wool, Yarn or fiber etc. by way of mechanical hesitation of textile in contact with the piece of specified adjacent fabrics in a soap soda solution followed by rinsing and dying.
The bath is having an arrangement to rotate 8 stainless steel jars containing the test solution and the test specimen above the horizontal axis at the specified speed.
The bath is heated by means of 2 emersion heater and the temperature is controlled by a capillary type Thermostat, which is displayed by a digital temperature indicator and can also be set with the preset counter as per the requirement.
After the mechanical hesitation the change in colour of the specimen and the standard fabric are assist by the standard grayscale.
Determination of water repellency of fabric against external wetting is carried out with the help of the spray tester. The Spray Test method is used for determining the resistance of any fabric, which may or may not have been given a water resistant/repellant finishing surfacing wetting by water. In this test, a specified volume of distilled water is sprayed on a Test specimen, which has been mounted on a ring and placed at an angle of 450, so that the center of the specimen is 150mm below the spray nozzle. The Spray rating is determined by comparing the appearance of the specimen with the standard Rating Chart.
Determination of water repellency, resistance to wetting (in term of water absorb) and resistance to penetration (in term of water penetrated) of fabric done by an instrument known as bundasmann type apparatus.
The bundasmann type apparatus made of four specimen holders which hold four specimens of the fabrics under test the specimen holders are rotate at the fixed RPM by means of a worm reduction gear box and an electric motor. The four specimen holders are mounted on teh assembly so that the specimens are titled at specified angle to the horizontal. Each sample holder is provided with four wiper arms fixed at right angle to each other and rotating about the axis of the cup. There are two aluminum tanks one at the bottom where the sample holder assembly is fixed and the other is fitted at the tp of the instrument, where the brass jets are fitted.
First specimen to come in contact, first with the pressure foot and later with the indenting tip under the specified contact load. Further movement of the platform causes the indenting load to act on the test specimen. Penetration of the indenting tip into the test specimen is determined with the help of a dial gauge fitted at the top of the pressure foot assembly. The contact between the dial gauge and the top of the plunger rod is made through an electrical arrangement to ensure that the weight of the stem of the dial gauge does not act on the test specimen. An electric buzzer is provided to slight vibrations to the plunger rod to eliminate friction. The dial gauge gives the depth of indentation in units of 0.01 mm which can be converted into IRHD hardness value.
