Development of Novel Natural Fibre Blends for Functional Textiles (QEID)

World consumption of natural fibres is expected to increase due to growing demand from health and eco-friendly consumers. There exists a good potential if attempts are made to exploit natural fibres like ramie, cotton, bamboo, eri etc. for promotion of apparel fabrics with newer appeal and comfort characteristics by blending techniques.

The main objectives of blending two or more fibres in predetermined quantities is to produce yarns and fabrics of improved quality, functionally and/or aesthetically that cannot be obtained by using only one type of fibres alone. The other purpose of blending is to economise the input mixing cost and improve the process performance. The individual characteristics of a fibre exert a greater or smaller influence in the blended textiles depending upon its proportion in the blend. The properties of yarns and fabrics made from the blend depend on the choice of fibres and their properties in the blend. Blended textiles are finding increasing application in highly diversified fields ranging from apparels to technical textiles. By blending, fabrics of novel types and with special effects can be produced for the niche market.

Ramie, an under exploited natural lingo cellulosic fibre ,also known as king of natural fibre finds stiff competition as a textile material due to its limited location specific availability and lack of knowledge of Degumming and processing. However, a lot of work has been carried out from time to time under different Research and development Projects in different research institutes, we have not achieved success for development of finer grade textile quality blended yarns. Ramie-cotton blend under A. P. Cess Fund project limited to 24s yarn in bulk quantity which is finer than commercially produced 100% ramie yarn developed on long staple spinning systems. Due to the unavailability of specialized ramie processing systems in India, novel blends of ramie with other natural fibres using spun silk spinning system and short staple spinning system needs to be developed which will produce finer binary and tertiary blended yarns for application in apparels and functional textiles. Fancy yarns and slub yarns are playing a significant role in textiles. Since there is no such research evidence of binary blended and tertiary blended yarns available, it is the high time to explore in the area of blended and slub yarns. Since ramie and Eri silk, both natural fibres belongs to the North eastern Region of our country, hence any technology developed will benefit the rural economy of N.E.H region of India.

  • To develop binary/tertiary blended yarn and slub yarn by ring/rotor/compact spinning technology.
  • To develop binary/tertiary blended yarn by spun silk processing technology.
  • To develop suitable fabric/product by weaving/knitting.
  • To develop suitable bleaching, dyeing and finish applications to blended materials
