Yarn And Carpet Testing Equipment

Carpet Abrasion Tester

Approx Price: Rs 75,000 / Unit 
Abrasion resistance is the most important property on which the durability of a carpet depends. Abrasion resistance of carpets is determined by abrading a circular test specimen against a specified abradant for various number of rubs and determining loss in mass versus number of rubs, or the number of rubs required to reveal the backing.

The GlobeCarpet Abrasion Tester consists of two vertical shafts rotating in the same direction at same speed with their centers offset. The specimen of carpet is clamped on the lower shaft and is rubbed against a larger circle of standard crossbred fabric clamped on the bottom of the upper shaft.

The rotations of the shafts are such as to give a constant relative velocity between specimen and abradant at all parts of the specimen. A counter is provided to record the number of rubs, with arrangement to stop the machine automatically after preset number of rubs. Means for applying a constant pressure by loading the upper shaft on the test specimen are also provided.

 

Crimp Rigidity Tester

Approx Price: Rs 65,000 / Unit 
Crimp Rigidity of a textured yarn gives a measure of its ability to recover from stretch. It is determined by measuring the percentage reduction of length of a skein of yarn immersed in water when a minor load replaces a major load.

For measuring crimp rigidity, a skein of known number of strands is prepared from the package of yarn under test. This skein is then immersed in water filled in a glass jar with a load of 0.1 g/denier/strand suspended on it. The length of the skein is measured on a scale. The load is then reduced to 0.002 g/denier/strand by replacing the major load by the minor load and the reading on the scale observed. Crimp rigidity is calculated from the readings obtained under the major and minor loads.

Crock Meter

Approx Price: Rs 70,000 / Meter 
One of the tests for determination of colorfastness of piled fabrics and floor coverings is the crocking test. This test is used for the determination of colorfastness against rubbing, either under dry or under wet conditions.

In this test a moving rectangular-shaped brass crock block of specified dimensions rubs against the test specimens under a fixed load. The amount of colour lost by the test specimen and the amount of color transferred to a piece of abradant fabric fixed over the base of the crock block are graded with the help of standard grey scales to evaluate the color fastness of the sample under test against rubbing.

 

The GlobeCrockmeter (motor operated) consists of a rigid flat metallic platform on which the test specimen can be held firmly and an abrading crock block that rubs against it under a specified load. The platform is fixed over the base of the equipment and lies in a horizontal plane. The test specimen is held firmly over an abrasive paper, which is pasted on the upper face of the platform, with two flat plates holding it at its ends.

Inclined Plane Flammability Tester

Approx Price: Rs 60,000 / Unit 

Flammability Tester of textile materials may be determined by various methods. One of the methods used for determination of flammability of textile materials is the inclined plane flammability test.

In this method, a test specimen taken from the sample under test is held in a sheet metal holder at an inclination of 45°. A flame from a standard jet is made to impinge on the upper face of the textile material near its bottom edge and the time taken for it to propagate through a distance of 127 mm determined to evaluate the flammability of textile material sample under test.

The Globe Inclined Plane Flammability Testerfor textile materials consists of a specimen rack for mounting the test specimen holder, a specimen holder in which the test specimens are held for conducting the test, arrangement to enable a standardized flame to impinge on the test specimen, and a timer to record the time taken by the flame to propagate through a distance of 127 mm. The various components are mounted inside a draught proof stainless steel sheet enclosure.

 

The specimen rack provides support for the holders in which the specimens are mounted. Its angle of inclination is 45°. The rack can be moved sideways to enable textile materials of different thickness to be set at the specified distance from the tip of the jet with the help of an adjusting screw. A built-in finger is provided to gauge this distance for setting it to the desired value.

      Martindale Abrasion Tester

      Approx Price: Rs 65,000 / pcs 
      Determination of resistance of any textile material to abrasion is usually carried out by abrading the textile material under specified conditions against a standard abradant. Although plane abrasion of 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.

      One of the standard equipment used for this determination is the Martindale Abrasion Tester. This apparatus gives a controlled amount of abrasion between material surfaces at comparatively low pressures in continuously changing direction. Circular specimens of textile material are abraded under known pressures under a motion, which is the resultant of two simple harmonic motions at right angle to each other. The resistance to abrasion is estimated by visual appearance or by finding the loss in mass of the test specimens.

      Rotary Platform Double

      Approx Price: Rs 75,000 / Unit 

      One of the methods used for determination of abrasion resistance of textile materials or coated fabrics is the rotary platform method.

      In this test a test specimen is abraded using rotary rubbing action. The test specimen is mounted on a horizontal circular platform and rotates at a specified speed. Two abrasive wheels are made to rest on the upper surface of the test specimen on either side of its centre. The wheels rotate because of friction between them and the test specimen, thus causing abrasion to take place. The wheels are loaded to apply the desired contact force. Abrasion resistance of the test specimen is evaluated either by finding the degree of abrasion after a specified number of rotations of the test specimen, or by determining the number of rotations needed to produce a specified degree of abrasion.

      Tuft Withdrawal Force Tester

      Approx Price: Rs 35,000 / Piece 

      The tuft withdrawal force tester is used to find the tuft binding strength of a carpet, which is the force required to extract a tuft from it. It is mainly used for determination of force needed to pull out tufts from unknotted tufted carpets.

       

      The GLOBETuft Withdrawal Force Tester has a spring dynamometer which carries a clamp for gripping a single tuft. The dynamometer is moved up and down with the help of a screw and hand wheel arrangement. A maximum load pointer is provided on the dynamometer to indicate the maximum force exerted on the tuft before it is pulled out.

       

      An opening in the base plate enables the test to be carried on a large area by placing the tester at the desired location. Small test specimens can be clamped over the base plate with the help of a clamping plate, which also has a similar opening in it.

      Exposure Rack

      Approx Price: Rs 80,000 / Unit 
      All dyed materials experience change in colour when exposed to daylight for a sufficiently long period because of the action of daylight on pigments used in them. The severity of exposure in both time and intensity of daylight determines the extent of change in colour.

      The colorfastness of any fabric is denoted by the number of the light fastness standard fabric that has changed colour to the same extent as the test specimen after a specified degree of exposure. It is expressed as the numerical rating for light fastness.

       

      The GLOBEExposure Rackis designed to test colorfastness of textile and leather materials to daylight. The test is carried out by exposing a set of light fastness standard fabrics 1 to 8 and a set of test specimens to daylight till the desired fading of the colour of the either the test specimen or light fastness standard 7 is obtained.

      Twist Tester

      Approx Price: Rs 70,000 / Unit 

      The strength of a yarn and properties of fabrics made from it depend to a great extent on the amount of twist given to it. Thus accurate determination of amount of twist in any yarn is of prime importance in assessing its quality.

       

      The amount of twist given to any yarn is usually determined by untwisting a known length of yarn and finding the number of rotations of one of its ends relative to the other needed to remove the twists completely. The equipment used for determination of twists of a yarn is known as Twist Tester.

       

      The GLOBETwist Tester consists of a set of clamps, one of which is rotating and the other fixed. The rotating clamp is driven by hand through a hand wheel and gear arrangement. A five-digit re-settable revolution counter counts the number of rotations of the rotating clamp.

      Crimp Tester

      Approx Price: Rs 15,000 / Unit 

      The crimp in a yarn is defined as the mean difference between the actual length of any yarn and its apparent length in the fabric after weaving. It is usually expressed as a percentage of the apparent length of the yarn in the fabric.

       

      Determination of the crimp of yarn is carried out by marking a known length on the fabric, removing the marked yarn in such a manner that it does not loose its twist, holding it between two grips at the marked points, and slowly extending it till it is subjected to a specified straightening tension. The increase in length of the yarn is determined and expressed as a percentage of marked length to obtain the value of crimp.

       

      The GLOBECrimp Testeris designed to determine the crimp of yarns taken out of fabrics. One end of the yarn is held in a pivoted loading grip on which the desired tension load is applied by means of a sliding weight acting on a lever arm, while the other end is held in a movable grip which is mounted on a screw and can move along the direction of the yarn, stretching it in the process. The distance moved through by this grip gives the extension of the yarn, and can be measured on a scale fixed by the side of the grip assembly.

      Yarn Evenness Tester

      Approx Price: Rs 70,000 / Unit 

       

      Visual determination of unevenness along the length of a yarn is carried out by wrapping it in equally spaced parallel wraps over a board and comparing the appearance of irregularities against standard rating photographs.

       

      To enable yarns of different thickness to be assessed, the spacing between the warps is suitably selected so as to give a clearly distinguishable pattern.

      \s

      The Globe Yarn Evenness Tester consistsof a yarn warp board and an arrangement to wrap the yarn over it at equal spacing under a desired tension. The board is rotated manual to warp yarn over it. The yarn is guided on to the board through a yarn guide, which moves parallel to the pivoting axis of the board with the help of a screw giving uniformly spaced wraps. The guide is positively linked to the rotation of the board with the help of a chain and sprocket drive. A set of change gears gives five different spacing for wrapping yarn of different counts. A spring loaded adjustable tensioning arrangement provides the desired tension to the yarn.

      Lea Strength Tester

      Approx Price: Rs 90,000 / Unit 

      Fabric Tensile Strength Tester/ lea strength of yarn is one of the major properties on which the suitability of yarn for its ultimate end use depends.

       

      The test for determination of lea strength consists of making a lea from the yarn with the help of a warp reel and testing it on the lea strength tester, which registers the maximum load at which the lea starts unraveling.

       

      The GLOBELea Strength Tester is constructed on a study fabricated steel structure with a heavy base plate which can be directly placed on the ground. The lea is placed between two pins, one of which is moving and the other is attached to a load measuring arrangement. The moving pin is driven through a screw arrangement driven by a motor and a worm reduction gearbox. Provision has been made for automatically stopping the motor at the extreme positions of the moving pin. Two movable pins are provided, one for testing metric leas of 1 metre swift perimeter and the second for testing imperial leas of 1.5 yards swift perimeter.
