Perspirometer SL-F11 Colour Fastness of dyed or printed fabrics against perspiration is determined by exposing the fabric sample to the action of both alkaline and acidic reagents while in contact with undyed adjacent fabrics is placed between plastic plates under a fixed load inside an oven maintained at 370 centigrade. The apparatus used for this test is called the Perspirometer. consists of a number of acrylic plates and which can be kept in suitable loading frame. The loading frame consists of two steel plates between which the acrylic plates placed. The test specimen are stitched between suitable white cloth pieces and dipped in either alkaline or acidic test solutions. The composite sample is placed in between any two acrylic plates. A number of test specimens can be loaded simultaneously between different sets of acrylic plates by stacking them one above the other. Loading is done by keeping a standard dead weight on top of the upper plate assembly, which consists of two parallel plates separated by suitable compensating springs. The guide rod attached to top plate of this assembly is locked while under load and the load removed. The springs compensate for subsequent variations in load due to variation in thickness of the test specimens on drying. The test is continued for the required time under the specified condition of temperature. After this the samples are removed from the frame and dried. The degree of staining of the while pieces of cloths and change in colour of the test specimens are evaluated using Grey Scales and compared against standard rating cards. All the components are made of stainless steel and are finished in black stoving enamel paint to give them a corrosion resistant finish.

Round Cutter / Sample Cutter A specialized instrument to determine the GSM of the textiles (Woven, Non Woven or Knitted, Fabrics) Our Round Cutter can be used for virtually any type of material including Film, Foam, Carpet Paper and Board. The unit is recommended for Yield Testing i.e. determination of weight per unit area. The sample cutter cuts out rapidly and accurately circular specimens of 100 Sq. cm. which is exactly One Hundredth of a Square Meter, the result in grams, multiplied by 100, gives grams per square meter. GRAMS Per Square METER = Specimen Weight in Grams x 100 TECHNICAL DETAILS : SPECIMEN AREA 100 CM2 SPECIMEN DIAMETER 113 MM (Approx) TYPE OF CUT STANDARD BLADES HEAVY DUTY(GERMAN) FOR LONG LIFE RUBBER PAD FOR THIS APPLICATION FOR REPETETIVE TEST WITHOUT FAIL. PROCEDURE : The Cutter has been specially designed to make it portable due to its light weight. Only the fabric has to gripped between cutter base and Rubber pad cutter top to be rotated gently clockwise direction for accurate cutting of fabric. The cut fabric can be weighed and multiplied by 100 to get GSM. MAINTENANCE : To maintain the efficiency of the Cutter: a) The Blades should be turned or changed when they become damaged or blunt. b) The Cutting Pad should also be changed, when it becomes worn out. Note:- For best results, only approved blades and pads should be used. ACCESSORY : For determining the weight per area, a weighing scale having the minimum sensitivity of 0.01 gm is required.
