Digital Printing
Digital textile printing is described as any ink jet based method of printing colorants onto fabric
Digital textile printing started in the late 1980s as a possible replacement for analog screen printing
With the use of easily accessible files, much more complex wide format printers: a vast amount of subtle effects and detail can be achieved

Edema Stocking
Developed by Ohmatex in Denmark
Electronic smart textile device that monitors and measures changes in leg volume for patients suffering from edema (fluid accumulation or swelling) of the lower limbs

New life Polyester Yarn Made of Recycled Plastic Bottles
New life is a polyester yarn made from 100% post-consumer recycled plastic bottles
It is processed by mechanical rather than chemical means
Made in Italy, the fabric is used in fashion, sportswear, underwear, medical garments and other clothes and furnishings
Georgio Armani used it to create a fashionable, eco-friendly gown for LIvia Firth at the 2012 Golden Globe Awards.

Future of Textile Industry
Sports and military industries
fabrics that help regulate body temperature, reduce wind resistance and control muscle vibration
Health & Beauty Industry
Drug-releasing medical textiles
Drug delivery through skin gel
Illuminated textiles for the photodynamic
treatment of tumors
Fabrics with moisturizer, perfume, & anti-aging
properties
Vilas Gharat. www.gharatandassociates.com 35Past Innovation Latest Innovation Future Innovations
Future of Textile Industry
Aesthetic Smart textile
Fabrics that light up to fabrics that can change color
Fabrics gather energy from environment by harnessing vibrations, sound or heat & reacts to input

Rotor Spinning
Jet Spinning / Vortex Spinning

Ring Spinning
Potential maximum speed of ring spinning: raised from 15,000 to 25,000 rpm with following Advances
Longer Frame: reduce the relative costs of
automatic doffing
Combination of spinning frame and winding
enhanced the adoption of automation
Automatic doffing: reduced doffing time thus package
(and ring) size was less critical
Splicing on the winder: yarn joins became less obtrusive — again offering
the potential of smaller package Smaller rings: for limiting traveler velocity (40 m/s), higher rotational
speeds (and hence twisting rates) could be achieved.
Longer Machines: increasing number of spindles per machine up to 1,800
Vilas Gharat. www.gharatandassociates.com 43
Ring Spinning
Innovation in Drafting System – High drafts in range of 70 -100
Developments in Ring Design
Orbit ring
Ceramic Ring
Rotating Ring
Spindle Identification
tracking of spindles from the ring frame: helps for Process quality control
Identification of spindles on the ring frame responsible for producing defective yarns
Increasing yarn quality as well as efficiency, by more readily indicating faulty positions on the spinning frame
Vilas Gharat. www.gharatandassociates.com 44
Compact Spinning Create yarns that are less hairy and stronger by use of
additional drafting
components and pneumatics Provides either a stronger yarn or spin at higher production speeds with
lower twist
Vilas Gharat. www.gharatandassociates.com 45
Rotor Spinning
Present state-of-the-art machines have significant integrated automation such as
Doffing
Piecing
Cleaning
Process/Product monitoring
Additionally, the machine can be part of a material handling system from sliver through to packaged yarn
Vilas Gharat. www.gharatandassociates.com 46
Jet Spinning / Vortex Spinning Murata Jet Spinning (MJS)
It offered high speed production of finer-count yarns
Several variants have been introduced, including Murata Twin Spin (MTS) and Roller Jet Spinning (RJS)
Different jets were offered to accommodate different yarn styles
To extend the use of jet spinning, with particular respect to fiber type and yarn count.
Murata Vortex Spinning (MVS)
Capable of spinning uncombed cotton slivers into acceptable yarns at speeds that were significantly higher than with any other system.

Weaving
Major developments in weaving machinery primarily geared up with objective of:
Higher productivity
Better quality
Reduction in number of operations through automation
Reduce cost of production
In recent years, beside above flexibility & improvement in machine utilization are receiving more attention by machinery manufacturers
Vilas Gharat. www.gharatandassociates.com 48
Developments in Weaving
Past developments in weft insertion systems:
Shuttle looms
Projectile looms
Rapier looms
Airjet looms
Waterjet looms
Multiphase looms
Other Developments like higher production system, microprocessor application, information technology, quick style change system, energy conservation, safety measures

Apparels
Apparels are still being produced as fashion textiles or as cheapest costumes
ideas correlating human beings needs with properties of textiles are yet to be explored.
The manpower require is very high & hence atomization is awaited.

Summary
Innovation is a continuous process
Need to eliminate lengthy textile processes
Costumes of Consumer choice, design and colour will directly be formed from granules or fibres
Need to have point of view on use of disposable textiles and apparels for events like drama, uniforms, sports activities, picnics etc
