Reformation in global trends


Technical textiles in Pakistan

• Although Pakistan’s potential in the field of technical textiles is immense but it is in the developing phase. Pakistan has always been a formidable force in the field of conventional cotton based textiles.


Difference b/w conventional &technical textiles • Unlike conventional textiles used traditionally for clothing or furnishing,

technical textiles are used basically on account of their specific physical and functional properties.

Conventional Textiles Technical Textiles


Agrotech • Textiles used in agriculture,

horticulture, forestry, farming and fishing


• Agrotech sheets are also used for soil reclamation.

• These sheets can contain soil erosion problem and decompose into plant nutrients.


•Provide protection against frost, wind,

excessive sunlight.

• Avoids crop wastage due to better symmetric arrangement.

• Provide

protection against weeds.

Agrotech


Bird Protection Nets


Biodegradable Plant Pots


Buildtech

• Buildtech involves textile composites used in building industry.


A revolution has been introduced to the building industry by the use of

textile based composites.

Self luminous textiles

• The textiles for disco clubs of future.


Geotech

As implied from the name Geo textiles are the textiles which work in contact with Earth’s basic elements; soil, rocks, water etc.


Dams • Geotextiles are used in

the construction of dams as concrete reinforcements.

• Used either in powdered or compact form.


Roads

• Geotextiles are being used in the construction of roads.

• Lahore Kalar-kahar Motorway.


Mechanism behind road construction

• Geotextiles fabric sheets are used due to their inherent stiffness.

• This does not let the roads deform easily, even if they are subjected to heavy traffic flow.


Prevention of soil erosion

• Lining of riverbanks can be done with Geotextiles to prevent soil erosion due to floods or other climatic conditions.


A chance lost!

• The damages due to recent floods could have been curtailed to a certain extent if geotextiles were given a chance!



• Erosion causes soil’s humus layer to erode away leaving the land barren/unavailable for cultivation.



• Geotextile sheets are used in plains, hilly or coastal areas to prevent soil erosion.


Geotech market

• Asia and other developing regions of the world are much likely to see a sustained infrastructure development programs.


Geotech market


Hometech • Home textiles includes

household textiles.

• One such article which has an interesting property is fragrant curtains.


Function and Mechanism

• Whenever there is some undesirable odor in the environment of a room these curtains would release fragrance to counter that odor.


Decoration purposes

• Litracon is also used as decoration article in home textiles as table lamps etc.


Hometech market

• The market is fairly mature in Western economies.

• The growth in emerging economies such as India and China is expected to accelerate.


Indutech

• The textile materials used in industries are known as indutech.

• Generally industech are used in purifying poisonous gases at high temperature.


Used in chimneys

• Most poisonous gases are discharged into the atmosphere at very high temperatures.

• Common materials can’t withstand such temperatures without melting.


Indutech has the remedy

• To solve this problem heat resistant textile materials with small pore sizes are used to filter hot poisonous gases.


Used as high strength ropes

• Indutech ropes are also used in industrial units.

• For lifting heavy weights and pulleys.

• These have high tensile strength.


As noise absorbents

• Some Industrial textiles are used at industrial scale as noise absorbents too.


Medtech

• Absorbents, Bandages: Plaster of Paris Bandage, orthopedics bandage, etc


Alginate bandages

• Alginate bandages can be removed without even the patient knowing about its removal and heals the wound faster.


Alginate Bandages “A Revolution”

• Wounds are not damaged as happens mostly when cotton bandage is removed.

• These bandages find their usage specially in burn care centers for acute burn injuries.


Germ absorbents

• Non woven germ absorbent wipes on handles of hospital doors.


Special tremor disease

• Boxer Muhammad Ali has the same disease.

• Due to hand tremor patient can’t carry out their daily choirs.


Medtech to the rescue!

• Special fabric gloves designed from piezoelectric material are designed to nullify the effect of these tremors.


In Transplantation

• Artificial kidney, Artificial liver, Artificial heart, Mechanical lung, grafts, artificial skin and bones are produced for transplantation.


Soothing Broken Bones and Hearts

• Textile based grafts and replacements of broken or damaged bones are also available for transplantation.


Magic healing

• Special environment for the treatment of various diseases like Asthma is required.

• Humidity, temperature or microbial activity is kept in check.


Magic healing

• Now we have such textiles available which can control these factors.

• Example of Khewra mine and a hospital situated in it for the treatment of Asthma.


How its done?

• The walls of the room of the patient is lined with fabric sheets made of these textiles.


Hernia

• The disease known as hernia makes the abdomen muscles weak.


Hernia

• Weak muscles cannot even hold the pressure of the intestines.


Development in Treatment Method

• The scientists have carried out the preparation of artificial hernia mesh (a fabric).


Mechanism

• It lets the abdomen muscles develop and takes up the pressure.

• Instead of letting it being transferred to the slowly developing abdomen muscles.


Curing hernia

• In this way the weakened muscles get time to develop fully.


Eye lenses

• Eye lenses are examples of technical textile materials.

• Very few of us know this.


Eye Cornea

• Recently artificial eye cornea has been developed with textile fibers.

• Cornea is the most important part of human eye.


Hope in sight

• Transplanting cornea in place of damaged or diseased cornea of a patient can give light to someone’s eye.


Relief for sugar patients

• Recently a major breakthrough for sugar patients has been the manufacturing of micro level fabric based drugs encapsulating insulin.


Mechanism

• It has an interesting mechanism.

• Capsules are injected into the blood stream by an injection.


Life of capsules

• The life of these capsules is 6 months at present.

• After this time span it is dissolved into non toxic materials.


No daily injections

• The greatest advantage of this technique is that patient doesn’t have to take insulin injections daily!

Carbon fiber as wonder fiber

• Carbon fiber is being presented as a replacement to aluminum alloys in fighter and commercial jet manufacturing.


New chapter of aviation history

• Boeing’s Airbus 380.

• Such fighter or commercial planes would be light weight and fuel efficient.


Eyebrow Raising Facts; Wonder Fiber

• It is much lighter than aluminum.

• Its single fiber is far thin than even human hair but still its strength surpasses that of steel.


Realization of Potential

• USA has devised a plan to shift 75% of its military vehicles to textile composite based structure.


Precious oil

• It is converting its military vehicles to Ethanol instead of gasoline.

• Ethanol is not as strong as gasoline.


Remedy

• To counter this problem the weight has to be reduced using textile based composites in vehicle structure.


Oekotech

• Textiles for environmental protection are known as Oekotech.(GREEN TEXTILES)


An interesting application

• Used effectively against oil spillages in coastal areas or in open oceans or seas, separates water and oil.(otherwise it is harmful to ecosystem)


Nothing goes to waste

• Separated oil can be used again, while on the other hand disasters can be averted.


In cigarette filters

• I bet you didn’t realize that over four trillion cigarette filters are manufactured annually.

• Cigarette filters are non woven textile materials.


Use of cigarettes filters

• These filters filter the tar and nicotine.

• Although handsome amount of it is inhaled but still it does filter these substance to some extent.
