Research Interest

A) Research on ecofriendly technologies

• Compostable sanitary napkin from agro waste :
  This project aims to address the dual ecological problems of non biodegradability of SAP based sanitary napkins on one hand and the burning of crop residues in North India, that leads to large scale air pollution, on the other hand. The aim of this study is to develop technology for use of locally available agro/ bio waste products for production of sanitary napkins that are compostable. Since there is a dearth of literature and standards on properties and performance requirements of sanitary napkins, a variety of commercially available sanitary napkins were tested and characterised in terms of physical properties as well as absorbancy characteristics. Method for testing and comparing the absorbancy of core layer has been standardised. Pure cellulose has been extracted from Pearl Millet stems and characterised. Research is going on to develop the process for production of an optimum sanitary napkin from these waste materials. Student: Manisha Yadav, Research Scholar

B) Textile Chemistry

• Surface functionalization and multifunctional finishes using natural materials :
  In general it’s a challenge to bind any chemical, particularly a natural polymer on textiles. Surface functionalization using physical methods such as irradiation with plasma or UV excimer lamp brings about physico chemical modifications in the textile at nano level, without affecting the bulk properties. A variety of finishes have been developed using natural materials which have been attached durably on cotton, wool, silk and polyester to create multifunctional effects.
• Sericin for finishing of textiles :
  The project is aimed at reducing heavy water pollution caused by discharging of silk degumming liquor containing large quantities of sericin, soap and alkali into the waste waters. Sericin- also a protein, has excellent oxygen permeability, cell protecting and antioxidant action, moisture regulating ability, protection from ultraviolet (UV) radiation and wound healing properties. Thus the product can be used to create value added multifunctional textiles. This will provide an additional source of income to the poor silk reelers and higher profits to silk processors. While conventional methods of sericin extraction make use of soap and alkali, in our lab., a greener and cleaner method was developed for extraction of sericin using Infra red laboratory dyeing machine and water. Higher yield of sericin was obtained at lower temperature and time of treatment. A protocol was proposed for characterization of extracted sericin in terms of physical and thermal properties, morphology, protein quality, structure and molecular weight. Polyester fabric could be imparted properties such as enhanced wicking, moisture regain, antistat, anti ultraviolet as well as anti oxidant ( anti ageing). Wool fabric was rendered shrink proof by imparting a sericin coating on UV irradiated fabric. Scaling up of the technology for commercialization is going on.
• Antimicrobial finishes using chitosan :
  Chitosan is another highly bioactive waste by product of the shell fish processing industry. Being polycationic in nature, chitosan exhibits strong antimicrobial properties. Application of a high molecular weight polymer on textiles poses several challenges. Studies were conducted to produce low molecular weight derivatives of chitosan and modification of chitosan was carried out to develop durable finish for cotton.
• Studies on natural dyes :
  In situ coloration of wool in a range of durable shades was carried out using potato juice and catechol. Curcumin could be durably attached to polyester textiles that were pretreated with UV radiation of 172 nm to create medical fabrics. Natural dyes were extracted from various plant sources and shade optimization done on natural and synthetic fibres. Mechanism of dyeing of textiles with plant dyes was established through theoretical studies. Technology for dyeing coir fibre with natural dyes was transferred to Coir Board. Series of workshops was conducted to train carpet weavers of India in the technology of dyeing carpet wool in deep and consistent shades.

C) Bacterial abundance on hospital textiles

Hospital textiles are known vectors of infections in a healthcare facility, yet very little is known about their role in spread of infections. In a series of studies, surveillance data for the number and nature of microbes present on nurses’ white coats has been generated and correlated with fabric properties. Understanding the mechanism of microbe- textile interactions can lead to design and selection of hospital fabrics which can minimise the adhesion, growth and transfer of microbes through textiles. This can work as an effective and affordable infection control strategy for India.

D) Design of Functional Clothing

• Design of Protective Gear for Indian motorcyclists :
  Motorcycling as a sport as well as a means of commuting is growing at a rapid pace in India. With the growing use of motorcycles, the number of accidents involving the same is also increasing at an alarming rate. Protective clothing use worldwide has been shown to reduce the incidence of injuries in motorcyclists. Indian weather and use conditions pose a unique challenge for clothing designers. Very little data is available on the ergonomic, physiological and social needs of Indian motorcyclists. This study addresses the subject in a holistic manner and adopts the “user oriented approach” for design of motorcyclists’ clothing. A detail survey of motorcycle riders across the country has been conducted to assess their habits, preferences and requirements from clothing. Kinematic analysis was employed to study the typical body postures of a motorcycle rider. It is well established that a static 2D anthropometry fails to accurately capture the dimensions of complex 3D human form and conventional patterns produced by 2D flat pattern methods fail to factor in the change in body shape and size during extreme postures. Hence patterns designed by these methods yield poorly fitting garments. Therefore in this study, virtual, 3D human body models were developed in selected dynamic poses using 3D body scanners. Kinematic patterns for jacket and trousers were designed and fit assessment was also carried on the 3D form using 3D softwares. Garment prototypes will be developed and evaluated by users for comfort, performance and aesthetics. Finally, the study will propose a step-by-step protocol that meets the triad of requirements namely protection, comfort and aesthetics for design of motorcyclists’ clothing using advanced technologies. The proposed approach can subsequently be applied to design any type of functional clothing for specific requirements.
  This work is being carried out in collaboration with Prof Sybille Kryzwinski of TU Dresden.

• Assistive clothing :
  There is a huge unmet need in the form of therapeutic clothing, designed especially for the Indian population. Products that are suitable for hot weather conditions, are comfortable and affordable are generally not available. I have been working in this area for the past four years mainly through design projects given to B.Tech. students. Some projects have been awarded under SURA or DISA grants. Several products have been developed and are in various stages of development- trials, prototyping or commercialization.
• a) Mamma Pod :
  Assistive device for Kangaroo mother care jacket for low birth weight babies. Indian Patent filed -3948/DEL/2015. Technology Transferred for commercialisation to M/s Vista Furnishing Pvt. Ltd., Noida in November, 2018.
• b) Wearables for children with Autism Spectrum Disorder :
  The project amalgamates design and technology to provide innovative solutions for children suffering with Autism Spectrum Disorder through wearable products. It explores the various possibilities in the areas of textiles, medicine and technology with design interventions that can provide future directions with regard to autism in the Indian context. Some of the products developed are as follows: Weighted compression vest
  The vest provides controlled proprioceptive input (body awareness) to the kid with deep pressure and balanced weight. Clinical trials show that the effect helps to calm and reassure the oversensitive child and decreases their hyper-responsiveness and has a therapeutic effect. Clinical trials completed by AIIMS.

• c) Physiogaming glove :
  An electronic Glove for rehabilitative compliance of autistic kids was designed. It was aimed to improve the motor coordination in kids aged 7-14 years suffering from cerebral palsy and similar conditions. We developed touch sensors using conductive silver fabric, which detected the finger pinching exercise. Later connected the glove as a controller to a self-developed game and embedded a seamless flexible waterproof circuit inside the glove by using e-textiles and Arduino Lilypad. The Project was awarded Summer Undergraduate Research Award (SURA), 2017 by Industrial Research and Development Unit, IIT Delhi.

• Structure property studies on elastic knitted fabrics for pressure garments :
  Pressure garments generate pressure on human limb. The amount of exerted pressure ranges in between 10-46 mmHg. The present study includes, the effect of different parameters affecting pressure generation behavior of the pressure garment on body. Single jersey circular knitted fabrics with inlay elastic yarn were prepared in varying input tension and linear density of inlay yarn. The effect of both the parameters on pressure generation was reported. The garment fit was varied at different levels and pressure generation on body was reported. The effect of body curvature and compressibility was also studied. The comfort characteristics of the fabrics at relaxed as well as extended state were investigated. A model has been proposed considering all the parameters to predict the pressure generation on human limb. The study is useful in engineering pressure garments.
