4. GLASS FIBER IN TEXTILE:
 Introduction
 Welcome to our presentation on glass fibre in textiles. Glass fibre is
a fascinating material with a wide range of applications in various
industries, including textile production. Today, we will explore the
properties and benefits of glass fibre in textiles, as well as some of
the challenges associated with its use.

5. What is Glass Fibre?
 Glass fibre is a type of reinforced plastic made from extremely
fine fibers of glass. It is known for its high strength-to-weight
ratio, making it an ideal material for a variety of industrial
applications.
 The fibers themselves are typically made from silica, which is
melted and then drawn out into thin strands. These strands are
then woven together to create a fabric or mat that can be used in
various manufacturing processes.

6.  Physical Properties
 Density – 2.50 – 2.55 g/cc
 Diameter - 10- 20 Um
 Tenacity – 6.3 - 11.7 g/den
 Extension at break (%) – 2.5%
 Tensile strength (Mpa) – 2000 – 3500
 Young’s modulus (Gpa) – 73
 Melting Point – 700c

7. Manufacturing Process:
 There are two popular manufacturing process of glass fiber.
1. Preparation of marbles, which are remelted in the fiberisation stage.
2. Direct melting route, in which a furnace is continuously charged with raw materials
which are melted and refined.
 Glass fibers are produced by rapid attenuation of the molten glass exuding through nozzles
under gravity.
 A solid intermediate stage (glass marbles) is thereby eliminated which, in particular, brings
about a reduction in the specific energy costs.
 It is common practice to melt E-glass (alkali-free glass) in spinning baths heated by natural
gas with recuperative heat recovery to achieve melting capacities of 6-20 t/day.

8.  Advantages of Glass Fibre in Textiles:
 Very high tensile strength
 Excellent resistance to sunlight and UV
 Excellent FR properties
 Good dimensional stability
 Zero moisture absorbance
 Resistant to mildew, rotting and insects
 Excellent UV stability

9. Challenges of Using Glass Fibre in Textiles:
 While there are many benefits to using glass fibre in textiles, there are also some challenges
associated with its use. For one, it can be expensive to produce, which can make it difficult
to compete with other materials on cost.
 Uses:
 Glass fabrics are used for interior furnishings wherever high demands are placed on safety,
e.g. in ships, hotels, cinemas, wall coverings, etc.
 Glass woven fabrics are use as bases for PTFE coatings for industrial uses, such as calender
belts and building structures.
 Fiberglass reinforcing sheets are used in PVC-backed carpet tiles.
 The fiberglass prevents creep of the PVC.
 Nonwoven glass and polyester fabrics are widely used in roofing applications.
 Glass fibres are almost universally used in place of asbestos.
 Glass fibers are also heat-resistant materials.

10. Fiber Optics Technology
Introduction to Optical Fibers.
 Fibers of glass
 Usually 120 micrometers in diameter
 Used to carry signals in the form of light over distances up to 50 km. .
 No repeaters needed.
Why Use Fiber Optics?
 Economics
 Speed
 Distance
 Weight/size
 Freedom from interference
 Electrical isolation
 Security

11. Conclusion:
 In conclusion, glass fibre is a fascinating material with a wide range of
applications in various industries, particularly in textile production. Its unique
properties, such as high strength and resistance to heat and chemicals, make it
an ideal choice for many applications.
