With globalisation and opening up of world market, assessment of quality attributes of both the raw material and finished products has assumed significance than ever before. Testing organizations who act as watchdogs for quality maintenance and compliance certification have a profound role to play in the current day market that is quality-driven catering to the ever-changing needs of the consumer. The emergence of Referral laboratories, accredited institutions and also mutual recognition agreements among accreditation organizations transgressing international barriers is manifestation and acknowledgement of growing importance of quality in world trade.

Textiles are an unique class of materials possessing high in-built variability as they are composed predominantly of natural fibres originating from biological systems that are subjected to the vagaries of weather. Coupled with this high inherent variability, their quality parameters and the assessment methodologies are highly influenced by the ambient conditions and their mechanical and chemical history. All the above factors contribute in good measure to the variability in their physical and chemical characteristics. A certain amount of inaccuracies and lack of precision are unavoidable leading to expression of results within a minimum permissible deviation.

The National Accreditation Board for Testing and Calibration Laboratories (NABL), the Indian accreditation body has adopted the ISO/IEC 17025 standards for implementation of its quality system. Increasingly all the textile testing laboratories are getting themselves accredited under this new set of guidelines. Estimation of Uncertainty in measurements that define the quality of the material under consideration is one of the mandatory requirements in ISO/IEC 17025 system.

Uncertainty is a parameter associated with the result of a measurement that characterizes the

dispersion in values that could be reasonably attributed to a measure. It states with confidence the range in which the actual value of test parameter would lie. Estimation of uncer-tainty in parameters that characterise the textile material becomes a compli-cated issue due to high variability associated with the material and the method of measurement as stated earlier. Since the beginning of implementation of ISO 17025 in textile laboratories, this topic has been the most widely discussed one among experts eluding a definite answer.

CIRCOT in association with therdian Fibre Society (IFS) has recently organised one day Workshop on "Uncertainty in Measurements for Textile Testing Laboratories" to provide a platform for meaningful dialogue among textile experts and shop floor personnel on this very important issue. Apart from presentations on the basic issues, discussions on a few case studies in detail were held so that the methodology of estimation could be understood and agreed upon by all concerned. The enthusiasm shown by the participants was ample proof for the success of the deliberations. A brief account of the proceedings at the workshop is presented in this newsletter. It is my sincere belief that the seminar would have served the purpose of clarifying certain lingering doubts about the estimation of uncertainty in measurement of quality parameters in textile material and would have paved the way for greater understanding of this complex issue.

Shri D.S. Tewari, Director, NABL, Lighting the Inaugural Lamp

(IFS) organised a one day workshop on Uncertainty in Measurements forTextileTesting Laboratories on March 12, 2004. In his inaugural address, Shri D.S. Tewari, Director, NABL said that uniformity of measurement is a global concern now. He said that measurement of uncertainty is the latest entrant to the list of elements for ensuring comparability of test results between laboratories. The purpose of ISO 17025 is to ensure technical requirements and quality system in the laboratory so that measured values are very close to true value. In the thematic address delivered on behalf of Dr. G.S. Nadiger, Director (Laboratories), Textiles Committee. by Mr. S. Subramaniam, Joint Director, Textiles Committee, it was stressed that ISO 17025 has made uncertainty calculations mandatory for testing laboratories also whereas earlier it was mandatory only for calibration units. The inaugural session was followed by two technical sessions and a Plenary Session, the details of which are as follows :

During the Plenary Session some discussions on 'True Value', Type A & B Uncertainties, etc, took place. Some of the members present felt that we in India should be able to create our own standards. There is need to have a National Institute for Creation of Certified Reference Materials and Standards on the lines of NIST, USA and Institutes like CIRCOT should take lead in its formation. Dr. S. Sreenivasan, Director, CIRCOT mentioned that the Institute has already started preparation of Calibration Cotton Standards which are being exclusively used by the Indian Industry. Dr. R.P. Nachane opined that CRM developments in other fields should be taken up by Institutions in the respective fields. National Institute for CRMs, if created, can coordinate this work.

Smt. Shashi Misra, Additional Secretary, DARE and Secretary, ICAR visited CIRCOT on 28-3-2004. She went round different Divisions to get a first hand knowledge about the research activities being carried out at the Institute. Later Smt.

NATIONAL SCIENCE DAY

The National Science Day, which marks the discovery of Raman Effect by the Nobel Laureate Sir C.V. Raman, was celebrated on February 28, 2004. The theme selected for this year was Encouraging Scientific Awareness in the Community. The year 2004 is also being

observed as the Year of Scientific Awareness. On this occasion Shri Kisan Mehta, President, Prakriti (NGO devoted to environmental protection) delivered a lecture on Technology in a Sustainable Life. The lecture dealt with the various ways in which one can use technology in our day to day life without affecting the environment. The lecture was well attended by the staff of CIRCOT

CIRCOT has developed a process for preparing different types of particle boards from cotton plant stalk. These particle boards possessing different density and thickness can be used in making wall panels, table top, doors, false ceiling, roof panelling, etc. Recently CIRCOT has empanelled a room with different types of boards made from cotton plant stalk. This room was inaugurated by Dr. Mangala Rai, Secretary, DARE and Director General, ICAR on December 26, 2003.

MICROBIAL PIGMENTS FOR ECO- FRIENDLY TEXTILE DYEING

CIRCOT has recently initiated a programme to make use of pigments obtained from microbes for dyeing textile materials. Pigments from three different microorganisms viz. Serratia sp., Monascus sp. and one from anaerobic bacteria were characterised and their application procedure for dyeing textile materials standardised.

It was noted that while the pigment from Serratia sp. could be used to dye nylon and wool, it could not impart any dye to cotton. The colouring material obtained from Monasus sp. dyed wool to a light orange shade while cotton to a very light colour. The pigment from anaerobic bacteria obtained from digester liquid showed no dyeing property for unmordanted cotton fibre. However, mordanted cotton could be dyed to a brownish yellow shade. Further studies on fastness characteristics of the dyed materials are in progress.

are obtained. The properties of enzymatically extracted and solvent extracted oil are found to be comparable.

The aqueous middle layer that contains hydrolysed protein of about 50% can be used to get good quality peptone in powder form. The properties of peptone obtained were found to be comparable with those produced by conventional means.

Thus, enzymatic extraction method apart from giving 80% oil recovery, also yielded a value added product, viz., peptone simultaneously.

Cotton fabrics are subjected to preparatory processes involving scouring, bleaching, washing, mercerizing, etc. prior to finishing or dyeing to obtain optimum effect These processes consume large quantities of water and energy. Apart from this, the effluents from pretreatments are hazardous and cause harm to the environment.

PLASMA TREATMENT ON COTTON FABRICS

Conventionally cottonseed oil is extracted by employing a screw expulsion or solvent extraction technique or by a combination of both methods. At CIRCOT, attempts have been made to extract oil by using enzymes wherein about 80 % oil could be extracted in 24 h. In this method, cottonseed meal after treating with a combination of enzymes is subjected to solvent extraction and centrifugation at room temperature. Three different layers viz. a top solvent layer containing oil, a middle layer with soluble protein, carbohydrates, etc and bottom layer with solid residue i. e. unhydrolysed protein

To circumvent this problem, CIRCOT has developed a method of processing cotton fabrics with plasma, (a mixture of partially ionized gases consisting of ions, electrons, neutral particles and radicals) in order to find out to what extent this treatment can substitute wet pre-processing. The effect of plasma on whiteness, yellowness, water absorbency, viscosity and dyeing behaviour of cotton fabrics has been assessed.

Results indicate that the effect of plasma depends upon the fabric used and the time of exposure. Most beneficial influence was obtained when grey fabric was treated with plasma for 5 min. This fabric had optimum water absorbency, improved whiteness and

the dye uptake value was on par with that of untreated bleached fabrics. This indicates that plasma treatment can replace the conventional alkali scouring and bleaching treatments without having any deleterious effect on dyeing properties.

CURRENT STATUS ON THE MAINTENANCE OF FIBRE QUALITY

OF CULTIVATED COTTONS

It has been a common observation that fibre qualities of cotton, that are under commercial cultivation on a large scale deteriorate over successive years. This could be due to the inadvertent / fraudulent mixing of varieties, mixing of different pickings, etc. apart from the influence of agro-climatic conditions. The lot-to-lot and bale-to-bale variation in fibre attributes among trade varieties is often too high coming in the way of manufacture of quality yarns acceptable to an export market. CIRCOT conducted a study in which fibre properties of 45 trade varieties/hybrids were collected for a period of seven years and analysed. The following pertinent observations could be made.

1. All the three fibre properties viz., fibre length, Micronaire and tenacity show wide variation. Over time and space, Micronaire value and bundle tenacity particularly display much higher variability for a given cotton.

2. Cottons such as LRA. 5166, S.6, F.1378 and Jayadhar show lesser variability in fibre attributes over the years indicating stability in their characters.

3. Even standard cottons grown under recommended conditions did exhibit more than acceptable variation in fibre parameters during different seasons.

Detailed study involving more standard and trade varieties is under way to find out the possible explanation for this behaviour.

UTILITY AND PERFORMANCE OF ADVANCED FIBRE INFORMATION SYSTEM IN EXPORT ORIENTED

UNITS — A SURVEY

Selection of suitable cotton and process control are two vital steps involved in quality control operations in any export-oriented units in the face of stringent specification for any imported product. In this context, the High Volume Instrument (HVI) and Advanced Fibre Information System (AFIS) play a major role.

A survey was conducted in and around Kolhapur (Maharashtra) to find out the utility of HVI and AFIS in enabling export-oriented units (EOU) to monitor the quality of raw material and end product. Following pertinent points emerged from the study:

1. The yarn realisation achieved by EOUs is around 70%. This low yarn realisation is due to the reason that all the EOUs are producing combed yarns, in which case the comber noil removed is on an average varies from 15 to 20%.

2. EOUs in Kolhapur region consume around 2.19 lakhs bales of cotton accounting for about 1.4% of India's cotton production. Yarn production of these EOUs mainly is by ring spinning. EOUs test 20% of their bales for AFIS fibre parameters.

3. Upper Quartile Length, 5.0% Length, Short Fibre Content, mTex, Immature Fibre Content, Maturity ratio, Neps/g and Seed Coat Neps /g are parameters that are put to use daily by EOUs in their

routine operations.

4. Among these eight parameters, neps/ gram is used by all the EOUs and the least used parameters are the 5.0% length and fibre millitex.

5. Neps per gram indicates the number of neps present in one gram of cotton. This is the parameter most extensively used by all the EOUs to study the performance of blow room, card and comber. As per the norms adopted by these mills, for roller ginned cotton, the neps per gram should be less than 180 and for saw ginned cotton it should not be beyond 250. Higher neps are allowed for saw ginned cottons, as the treatment in saw gin is harsh and produces more neps than roller gin.

A biogas plant based on cyclone-dust has been installed in Century Textiles and Industries Ltd., Mumbai under a consultancy scheme. There are two batch fed digesters which can handle four tonnes of cyclone-dust each and a common gas holder with a storing capacity of 35 m 3 . After charging the digester, the combustible gas generation starts after 15 days and continues for 60 days after which recharging is done. The gas produced is currently being utilised to run the canteen in the mill.
