CIRCOT-Bajaj Cotton Pre-cleaner

The trash content is a predominant parameter to decide the grade and bale value of the cotton besides other quality attributes. High trash content deteriorates the colour grade of cotton and also increases the wear and tear of ginning machinery parts. Higher trash content in Indian cotton forced the spinning mills to resort to cotton imports. Thus pre-cleaning of cotton assumes significance to reduce the trash content from the seed cotton so as to improve the ginning performance and lint quality. ICAR-CIRCOT has developed the inclined and horizontal pre-cleaners for cotton.

Value Addition to Naturally Coloured Cotton

Commonly cotton lint is white. But, some cotton varieties bear colours.
Naturally Coloured Cotton (NCC) is naturally pigmented fibre that grows in shades of brown, green, tan, blue, black etc.
ICAR-CIRCOT took up the challenge for commercialization of these varieties and successfully developed technology to spin good quality yarn though the cotton grown has short staple length.
Various products from this fabric such as Jackets, Handkerchiefs, Infant wears have been developed out of NCC spun yarn.
These products are 100% chemical free, has very high wash durability (due to inherent colour), soft feel and skin friendly.

Accelerated Process for preparation of bio-enriched compost

Cotton farmers, after harvesting the bolls, leave the entire plant stalk in the field or burnt, resulting in environmental pollution. Also, routine biomass composting process will not work for cotton stalks due to their hard woody nature. The conventional composting process will take 3 to 6 months, depending on the process conditions. Hence, ICAR-CIRCOT developed an accelerated process of cotton stalk composting using microbial consortium. Duration of composting is 45 days for wet and 60 days for dry cotton stalks. It has higher NPK value compared to normal composting, resulting in better soil health.

ICAR-CIRCOT Cotton Lint Opener

Cotton quality parameters are essential in determining the market value of the cotton and its use along the cotton value chain. The fibre quality parameters viz., Length, Strength, Micronaire etc., are assessed using High Volume Instruments (HVI). The cotton samples, drawn from densely packed bales, for quality assessment should be opened up without any quality deterioration for the accuracy of the measurement. Generally, cotton sample opening is done manually, which is tedious and also unscientific, or by using a trash analyzer which is time consuming and results in damage to fibres. ICAR-CIRCOT has developed the Cotton Lint Opener to prepare the cotton samples that can be used for quality assessment in modern testing equipment.

ICAR-CIRCOT Nanofertilizer Technology

A field experiment conducted at M/s. Rashtriya Chemicals and Fertilizers Ltd., Mumbai (RCF) experimental farm demonstrated the effect of Nano-Zn in combination with N:P:K (15:15:15) complex fertilizer “Suphala” of RCF Ltd. on growth attributes of brinjal (Solanum melongena L) as well as nutrient use efficiency. Nano-Zn synergistically enhanced the yield (70%) and biomass (45%) in brinjal.

ICAR-CIRCOT Portable Laboratory Model Gin

The quality of cotton samples can only be assessed after ginning i.e. separation of fibres from cottonseed. Cotton is ginned in India on commercial size Double Roller (DR) and Saw Gins, which were not feasible for ginning of small cotton samples required for assessing fibre quality attributes. ICAR-CIRCOT Portable Ginning Machines provides the solution for quick ginning of small quantity of cotton samples to assess the fibre quality for the benefit of Cotton traders, graders, ginners and researchers. It helps farmers to obtain seed for sowing.

ICAR-CIRCOT’s Technology for Value Addition to Agro-Residues: Waste to Wealth

ICAR-Central Institute for Research on Cotton Technology (ICAR-CIRCOT), Mumbai with vast experience and expertise in technology development and commercialisation, supported many start-ups to develop novel and marketable products from agro-residues. A Kerala based start-up, M/s. Rubber Engineers Enterprises, Thrissur, Kerala developed Natural Rubber based Fibre reinforced Garden pots with the technical inputs from ICAR-CIRCOT. These pots are flexible, degradable, long lasting and a potential substitute to plastic, terracotta and cement pots. This product enhances the use of natural fibres in a different spectrum of application.

ICAR-CIRCOT’s Calibration Cotton – A Standard Reference Material of high quality

High volume instrument (HVI) used for assessing the quality of cotton fibres needs calibration using the Standard Reference Material (SRM), popularly known as ‘Calibration Cotton’. Earlier United States Department of Agriculture (USDA) has been supplying “Calibration cotton” all over the world; now, ICAR-CIRCOT is also supplying Calibration cotton. ICAR-CIRCOT has developed the indigenous calibration cotton through ICAR revolving fund scheme during 1997 as an import substitute. Since then, it is supplying prepared calibration cotton to spinning mills, cotton trading houses, research institutes, Government agencies and overseas companies.
