The count of yarn is defined as a number indicating its Weightage. In Direct System, the count is the weight of a Unit Length of yarn. For example "TEX" is number of grams in one-Kilometer Length of yarn, "Denier" is number of grams in 9000 meters of yarn. In Indirect System, the count is the number of unit of fixed length of yarn which make a fixed weight: For example "Cotton" is number of hanks of yam in a pound, "Metric" is number of Kilometers of yarn in one Kilogram. Irrespective of the system of count, two basic requirements for determining count are
  1. An accurate determination of Sample Length, and
  2. An accurate determination of its Weight.

flammability testing instruments
It is a Single Channel/Probe Equipment, with advanced electronic circuitry & controls having latest control panel, which eliminates all chances of the broken parts of the needle and iron particles passing by in a Garment. It can detect any iron particle as small as 1.0 mm, safe -t is a 10 sensor unit, which ensures its accuracy and dependability. The lightening indicator on the digital control panel makes it convenient for the operator to find the exact location of the broken needle. Further the Digital Counter on the panel can also calculate how many units have successfully passed the test and how many have failed and will also give the value of the total number of products tested on the unit. Complete unit with a calibration certificate, traceable to NPL, along with an inspection and conformance certificate.

flammability testing instruments
The Presto Conditioning chamber is a ideal environmental chamber with the latest technology used to create the designated temperature. It has the lowest heat loss ratio due to high quality of insulation with imported glass wool. The chamber has a sealed compressor unit for high speed 'almost instant' cooling. Ergonomics and user ease are given a lot of importance while designing the system. It has complete Digital controls. Viewing: Viewing Glass incorporated for visual Examination of sample, with neoprene sealed lining.

Humidity Control & Temp. Controller : Digital preset controller for both humidity & temperature, Solid State type with memory facility in case of power failure the settings are retained, no need to re programme.

Shelves : 2 nos. perforated Stainless Steel Shelves provided for ease of humidity circulation.

Timer : Digital Pre-Set solid state type Timer to set OFF Chamber after set number of hours. It has a built in battery for memory back of settings in case of power failure, the programming need not be done again.

Hour Totaliser : Records total cumulative number of hours the instrument has run totally automated controls for zero attendance and auto shut off.
Construction : An aesthetically designed control panel would be provided with colour coded wiring and only ISI marked electricals would be used where ever possible. All safety measures like fuses etc would be incorporated in all areas.

Size : 18" x 18" x 28"
Humidity : Range 65% - 95% (tolerances of 5%)
Temperature Range : Ambient to 65 deg. C.

Measurements of Yarn Thickness.
Evaluation of Yarn Hairiness.
Evaluation of Mercerization of Yarn.
Maturity Test for Cotton Fibers.
Identification of Fibers etc.


Mechanical Stage : Graduated Mechanical Stage with X & Y Forward &
Backward : Movement and Left & Right Movement)
Screen Pointers: Two : One Arrow & One Circle Pointer on the screen
