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

Trang 7

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

Trang 47

Roads

• Geotextiles are being

used in the construction

of roads

• Lahore Kalar-kahar

Motorway

Trang 48

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

Trang 49

Prevention of soil erosion

• Lining of riverbanks can

be done with

Geotextiles to prevent

soil erosion due to

floods or other climatic

conditions

Trang 50

A chance lost!

• The damages due to

recent floods could

have been curtailed to a

Trang 51

• Erosion causes soil’s

humus layer to erode

away leaving the land

barren/unavailable for

cultivation

Trang 52

• Geotextile sheets are

used in plains, hilly or

coastal areas to prevent

soil erosion

Trang 53

Used in chimneys

• Most poisonous gases

are discharged into the

Trang 61

Indutech has the remedy

• To solve this problem

heat resistant textile

materials with small

pore sizes are used to

filter hot poisonous

gases

Trang 62

Used as high strength ropes

• Indutech ropes are also used in industrial units

• For lifting heavy weights and pulleys

• These have high tensile strength

Trang 63

As noise absorbents

• Some Industrial textiles

are used at industrial

scale as noise

absorbents too

Trang 65

Alginate bandages

• Alginate bandages can

be removed without

even the patient

knowing about its

removal and heals the

wound faster

Trang 66

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

Trang 68

Special tremor disease

• Boxer Muhammad Ali

has the same disease

• Due to hand tremor

patient can’t carry out

their daily choirs

Trang 69

Medtech to the rescue!

• Special fabric gloves

designed from

piezoelectric material

are designed to nullify

the effect of these

tremors

Trang 70

In Transplantation

• Artificial kidney,

Artificial liver, Artificial

heart, Mechanical lung,

grafts, artificial skin and

bones are produced for

transplantation

Trang 71

Soothing Broken Bones and Hearts

replacements of broken

or damaged bones are

also available for

transplantation

Trang 73

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

Trang 74

How its done?

• The walls of the room

of the patient is lined

with fabric sheets made

of these textiles

Trang 75

Hernia

• The disease known as

hernia makes the

abdomen muscles

weak

Trang 76

Hernia

• Weak muscles cannot

even hold the pressure

of the intestines

Trang 77

Development in Treatment Method

• The scientists have

carried out the

preparation of artificial

hernia mesh (a fabric)

Trang 78

Mechanism

• It lets the abdomen

muscles develop and

takes up the pressure

Trang 79

Curing hernia

• In this way the

weakened muscles get

time to develop fully

Trang 81

Eye Cornea

• Recently artificial eye

cornea has been

developed with textile

fibers

• Cornea is the most

important part of

human eye

breakthrough for sugar

patients has been the

manufacturing of micro

level fabric based drugs

encapsulating insulin

Trang 84

Mechanism

• It has an interesting

mechanism

• Capsules are injected

into the blood stream

by an injection

Trang 85

Life of capsules

• The life of these

capsules is 6 months at

present

• After this time span it is

dissolved into non toxic

materials

Trang 86

No daily injections

• The greatest advantage

of this technique is that

patient doesn’t have to

take insulin injections

daily!

• It is much lighter than

aluminum

• Its single fiber is far thin

than even human hair

but still its strength

surpasses that of steel

Trang 100

Remedy

• To counter this problem

the weight has to be

reduced using textile

based composites in

vehicle structure

Trang 102

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)

Trang 103

Nothing goes to waste

• Separated oil can be

used again, while on the

other hand disasters

can be averted

Trang 104

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
