- Development of High Strength Cost Effective Seamless Technical Circular Fabric from Heavy Denier Multifilament Yarns for Geotechnical Applications
The project is aimed at developing an effective indigenous solution for ground improvement in weak and problematic soils through Geotextile Encased Stone Column (GESC) applications. Although GESC technology has demonstrated significant effectiveness in enhancing the engineering performance of soft ground, its wider adoption has been constrained by the non-availability of suitable high-strength seamless tubular geotextiles in the domestic market. The present project addresses this critical gap by focusing on the development of seamless technical circular fabric structures from heavy denier multifilament yarns, with the objective of improving the load-bearing capacity and overall stability of weak subsoil strata. In parallel, the project also seeks to establish a cost-effective indigenous manufacturing technology for producing such seamless circular geotextile fabrics, thereby reducing dependence on imported materials and systems.
As part of the development programme, a comprehensive review and technical assessment of various stone column and ground improvement techniques have been carried out to identify the specific functional requirements of geotextile encasement systems. The study indicates that subsurface formations characterized by low undrained shear strength, loose sandy deposits, and silty or clayey sand strata are among the most suitable candidates for improvement through stone column reinforcement supported by geotextile encasement. The seamless tubular geotextile developed under the project is intended to provide effective lateral confinement to the granular column material, thereby improving column integrity, reducing radial deformation, and enhancing the composite ground response under applied loading conditions.
The dedicated machinery required for manufacturing the seamless circular technical fabric has been successfully developed. The underlying technology has been granted a patent (Patent No. 506705), and the developed technology has also been transferred to M/s. Lohia Corp., indicating its strong commercialization potential.
- Development of Next Generation Impact Resistant High Strength Agrotextile Hail Protection Net for Horticultural Applications
Agrotextile hail protection nets are widely used in agriculture to shield crops from hailstorms and adverse weather conditions. These nets typically use high-density polyethylene (HDPE) or polypropylene (PP), known for their lightweight and durable properties. While these materials are affordable and easy to produce, they have several limitations in terms of impact resistance, customization, and longevity This project introduces innovative solutions to improve agrotextile hail protection for horticultural applications. The proposed technology for high-strength, impact-resistant agrotextile hail protection nets represent a significant improvement over existing solutions, addressing key limitations and offering innovative advancements. By incorporating advanced nanomaterials and engineered fabrication techniques, the hail protection nets provide robust barriers against high-speed impacts, minimizing crop losses and safeguarding agricultural livelihoods.

- Phase- II of Reusable Adult Urine Incontinence Product Development
Urinary incontinence (UI) is a common symptom affecting men &women of all ages. It is a stigmatizing problem and has a profound impact on health, in particular on social and psychological well-being. In Phase-I of the project, SASMIRA has developed reusable urine incontinence absorbing prototype products that are evaluated at laboratory level for their performance. The proto-types thus developed are tested for all their functional properties at lab levels i.e. the product is developed up to Technological readiness level (TRL) 4 and further needs to be developed to TRL 8 before being taken up for commercialization. Now, the proto-types need to be tested for presence of restricted chemicals, biocompatibility, skin irritation test, cytotoxicity and evaluate product performance in UI patients before accelerating the technology for commercialization. Such work has been undertaken in Phase-II of project.

1) Development of Biodegradable fishing nets for combating ghost fishing
This is the first R&D project sanctioned to SASMIRA by the State Fisheries Department in collaboration with CIFT, ICAR, aiming to develop biodegradable fishing nets. Samples have been developed using hydrophobic coatings on yarn to enhance the longevity of the fishing gear, and performance evaluation under real-world conditions is being carried out at CIFT, Vashi. Polyester yarn with biodegradable additives is also being developed, and various fishing gear samples are being developed and are undergoing characterization for optimization. The prototype development and studies for biodegradable fishing gear are in progress.
