Medical Textiles

Provides bio receptive and biocompatible material

Remarkable Application

“Artificial Heart Valve”:

Made from pyrolytic carbon, used for over 30 years

Bi-leaflet designs, meaning that they employ two carbon “leaflets” to regulate flow to a single direction

Sport Textiles

Provides light weight material with safety features that are Tougher than wood

Breathes like skin

Waterproof like rubber

Eco-friendly & highly economical

Advantages Moisture management

Good perspiration fastness

Flexibility

Good heat conductivity

Immense comfort

Superior strength and durability.

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

Latest innovations in Textiles

Nano Polymer technology

Nano polymer coatings imparts amazing new properties to materials

Increasing effectiveness

Decreasing maintenance time and cost

Nano Coating: Stainless material Provides superhydrophobic textiles

completely water and oil repellent textiles

Easy cleaning

Invisibility

Universal

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 innovations in Textiles

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

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

SPINNING

WEAVING

PROCESSING

Spinning

Ring Spinning

Compact Spinning

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

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

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

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

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

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

Need of InnovationsVilas Gharat. www.gharatandassociates.com 52

Eco friendly Textile Processing

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.

Spunbond & Spunlace

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
