Transcript

<ul><li><p>Testing &amp; Analytical Equipments for Wet Processing</p><p>1 of 2</p><p>Testing &amp; analytical equipments for wet processing industries:Analytical Services Laboratory is equipped with both traditional equipment &amp; modern instrumentation.There are 3 main functions within laboratory:1) Technical service: Analytical Services Laboratory uses both traditional &amp; advanced analytical techniques to</p><p>help textile wet processing industry troubleshoot special problems. Range of samples varies from cottonfiber to finished garments.</p><p>2) Research support: Results from standard analytical &amp; textile chemical tests provide researchers with basicinformation before a project begins &amp; help to define final results. Advanced instrumental techniques arealso used to gauge outcome of a project.</p><p>3) Methods development: For support of both research &amp; production efforts, new analytical methods areoften required to provide required information. Existing analytical methods may be modified or entirelynew methods may be developed to meet these needs.</p><p>StaffsLab should be staffed with chemists &amp; technicians with experience in both analytical techniques &amp; supportservices to textile industry.Services to be done:In addition to 03 main functions given above, services below should be available on a routine basis:</p><p>Test methods Absorbency Alkalinity Chemical Damage Degree of Mercerization Dyestuff Classification/Identification Extractables (Water, Solvent, Enzyme) Fiber Content Formaldehyde pH Presence of Resin Spot Tests for Size, Iron Sugar Content</p><p>Titrations Caustic (NaOH) Hypochlorite Peroxide</p><p>Instrumental analysis FT-IR NIR</p><p>Equipment Typical usesMetrohm Titrator (Model 716 DMS Titrino) Automated titrationsFisher Accumet pH Meter pH &amp; mV measurementsSartorius Analytical Balance (Model ME 254S Genius) Weighing to the nearest 0.0001gmSartorius Top Loading Balance (Model LA 5200P) Weighing to the nearest 0.01 gmSpectronics Unicam (UV1) Ultraviolet-VisibleSpectrophotometer</p><p>Quantitative measurements of solution that absorb inUV-VIS region of spectrum</p><p>Varian Fourier Transform Infrared Spectrophotometer(Model FTS-7000) with UMA 600 microscope</p><p>Identification of organic &amp; some inorganic materialsincluding microscopic samples; used extensively intechnical service applications</p><p>FOSS/NIR Systems Near Infrared SpectrophotometerXDS &amp; Fiber Optic Probe</p><p>Identification of fibers, blends, or spots on fabrics;degree of mercerization</p></li><li><p>Testing &amp; Analytical Equipments for Wet Processing</p><p>2 of 2</p><p>Extraction Equipment (Soxhlet &amp; Ultrasound) Extractions for identification /quantitative analysisCarpet Flammability Tester Pill testHitachi Video Microscope Isolation of contaminants &amp; visual inspection of</p><p>samplesBchi Rotary Evaporator (Model R-124) Concentrating liquids &amp; recycling of solventsMechanical Convection and Forced Air Ovens Drying of samplesCEM Microwave (MARS 5) Rapid digestion of solid samples for subsequent</p><p>analysesAssociated Environmental Systems ControlledTemperature &amp; Humidity Chamber (Model HD-464)</p><p>Condition samples for flammability testing</p><p>AnalytikJena Atomic Absorption Spectrophotometerwith Flame &amp; Graphite Furnace (vario 5)</p><p>Determination of metals</p><p>Sartorius Microbalance (Model MC5) Weighing to nearest 0.00001gmGovmark 45 Degree Tester (TC-45) General wearing apparel flammabilityGovmark Vertical Tester Vertical flammability and Childrens sleepwear</p><p>Statements, recommendations, &amp; suggestions contained herein are based on experiments &amp; information believed to bereliable only with regard to products&amp;/or processes involved at time.
