Smoothness Tester for Textile Sheeting Materials
To assess performance of smoothness property of fabric, NITRA has invented first-of- its-kind instrument to accurately measure the smoothness properties of fabrics. The instrument works in a closed chamber. Two versions of instruments are developed as per the need of customers. The first version is available for those customers who are having RH and temperature controlling facility in their laboratory. This version is having no provision for controlling temperature and RH inside the chamber. In the second version, facility of controlling temperature and RH inside the chamber is provided.
Electronic Drape Meter Based On Image Analysis Technique
Laboratories are using conventional Drape meter which has several drawbacks like: • Slow process and too much dependent on the operator • The accuracy can get affected if there is small variation in drawing and cutting. This happens quite often. • The accuracy of weighing can change the result (for 0.1 gm variation the DC can change by 2.5 to 3.0% absolute value) To overcome these problems and provide accurate & reliable results, NITRA has developed electronic drape tester using image analysis techniques. Uniqueness of this development is that results will be provided by the software in pdf format. Human error during measurement is totally avoided. Technology of NITRA Electronic Drape Meter was transferred to M/s. Dinu Technologies, Coimbatore. It has given license to manufacture NITRA Electronic Drape Meter.
Flammability Tester (As per BS 5438)
This instrument is developed as per BS 5438 and is used to determine the effect of fire on textile materials in vertical mode
Flammability Tester (As per IS 11871 Method A)
This instrument is developed As per IS 11871 Method A and is used to determine flammability behaviour  of  textile material when specimen is placed in vertical position.
Smoke visibility test apparatus (As per UIC code 562 – 2 Appendix 15)
This instrument is developed as per UIC 564-2 Appendix 15 and is used to determine the effect of smoke generated on visibility.
Fire resistant test apparatus (As per UIC code 562 – 2 Appendix 5 and 12)
This instrument is developed as per UIC 564-2 and is used to determine the effect of fire on various materials.
Limiting Oxygen Index Tester
This instrument is used to determine Limiting The limiting oxygen index of textiles and plastic material. oxygen index (LOI) is the minimum concentration of oxygen, expressed as a percentage, that will support combustion of a small vertical test specimen under specified test conditions. It is measured by passing a mixture of oxygen and nitrogen over a burning specimen. This instrument is based on IS 13501.
Toxicity Tester
This instrument tests the toxicity of the products of combustion in terms of small molecular species arising when a small sample of a material is completely burnt in excess air under specified conditions
Friction Tester
The main feature of this instrument is that the instrument measures frictional coefficient of Fiber to Fiber and Fiber to metal
Fabric Hand Tester
The main features of this instrument are that it Quantifies handle and results are formatted analytically and graphically which are easy to interpret.
Draftometer (patented)
The main features of this instrument are that It can measure the drafting in a dynamic condition, simulating actual drafting conditions of sliver and rovings. The data analysis is done through dedicated software. Useful to analyse the spinning performance of spin finishes and dyed fibers.
Dimensional Stability to Dry Heat Tester
This instrument is very useful to determine the effect of full garment iron (dry heat) on the dimensional stability of fabric. The instrument is based on IS 12170 (referred specification IS 15853).
Soil Release Efficiency Tester
This instrument is used to determine the ability of soil release of textile material after treatment with various types of soils. The instrument is based on IS 11813 (referred specification IS 15853).
Elastane Yarn Count Tester
The main feature of this instrument is that leas of elastane/stretch yarns are prepared under uniform & standard tension.
