3. MILK FIBER
• Milk fiber is a blend of casein protein and the chemical
acrylonitrile, which is used to make acrylic.
• It was manufactured from milk casein to compete with
wool.
• It’s made using a process that is similar to rayon/viscose.
• It reacts like wool.
• That it dyes like wool and even smells like wool when
burned.

4. CHARACTERISTICS OF MILK FIBER
• In Milk fiber, the natural protein humectant factor is present, which
makes the skin delicate and smooth.
• It absorbs moisture very well as it is hygroscopic in nature.
• It is antibacterial and antifungal as amino acids presents in the
fiber.
• It is glossy and luxurious in appearance, feel and comfortability,
just like Silk.
• It is very easy to dye and can be dyed under normal temperature.
• It can be blended well with other different fibers, such as Tencel,
Cotton, Bamboo, modal fiber.

5. FIBER PROPERTIES
• Good moisture – absorption.
• Excellent dyability.
• Comfortable, white, fluffy and springy.
• PH of 6.8 (same as the human skin)
• Can be blended with most any fiber.

6. PRODUCTION PROCESS OF MILK FIBER
Raw Material
Mixing
Filtration
Deareation
Spinning
Cutting
Hardening
Washing
Drying
Baling

7. PRODUCTION PROCESS OF MILK FIBER

8. BLENDING OF MILK FIBER
The popular blends were
• wool- 94% and casein fiber -6%
• viscose-50% and casein fiber-50%
• Casein/cotton blends are popular
for hosiery and carpets
• A small amount of fiber is used for
100% casein goods, but most
casein fiber is blended with wool,
cotton, rayon, nylon and other
staple fibers.

9. PHYSICAL PROPERTIES
Tensile strength:
• Milk fiber has the tenacity of 2.8cN/tex when it is dry. When wet the fibers
lose much of their strength then tenacity falls to, 2.4 to 2.6cN/tex.
Thermal Properties:
• Milk fibers generally soften on heating, particularly when wet. Fibers
become brittle and yellow on prolonged heating.
Effect of Moisture:
• Milk fiber tends to absorb moisture readily and the fibers become swollen
and soft they may become plastic and sticky as the temperature is raised.
Elongation:
• 60-70% wet or dry.
Effect of Age:
• Very resistant.

10. CHEMICAL PROPERTIES
Effect Of Acids:
• Milk is stable to acids of moderate strength under normal conditions.
Effect Of Alkalis:
• Milk is sensitive to alkali.
Effect Of Organic Solvants:
• Dry cleaning solvents do not cause damage.
Insects:
• Milk fiber is not attacked by moth grubs to the same degree as wool.
Micro-organisms:
• Milk fibers are attacked by mildews, particularly when moist.
Electrical Properties:
• Dielectric strength of Milk fibers is low.

12. ADVANTAGES & DISADVANTAGES OF
MILK
• It is hygienic and flexible.
• It is highly smooth, sheen and delicate.
• It is moisture absorbent, permeable and heat resistant.
• It is color fast and easily dye able.
• It can be blended with other fiber.
• It is renewable, biodegradable and eco-friendly fabric.
• It is great for sensitive skin as it has the same pH level as
human skin.

13. • It is environment- friendly and is considered as green
product.
• It contains 15 amino acids and natural anti-bacterial rate is
above 80 percent so it has sanitarian function.
• It gets wrinkles easily after washing and needs to be ironed
every time.
• It should not be washed in machine and that is because its
not a very hard fiber
• It has a low durability.
• It is expensive.
DISADVANTAGES

14. Applications Milk Fiber And Care
APPLICATIONS
• Intimate garments.
• Children’s garments.
• T-shirts.
• Women’s garments.
• Sports wear.
• Bedding.
• Eye mask

15. WASHING
• Garments containing milk fiber should be washed with care and treated
very gently. High temperatures and strong acid or alkaline condition
must be avoided. Neutral detergents are preferable for washing.
DRYING
• Garments should dried as wool, care being taken to avoid high
temperatures.
IRONING
• The full, soft handle of garments containing casein will be maintained if
they are slightly damp or almost dry before being ironed or pressed.
DRY CLEANING
• Milk fiber is not affected by dry cleaning solvents and garments
containing casein can be dry cleaned readily as wool.

16. CONCLUSION
• Milk Fabrics are so skin-friendly that itself makes us
feel better. This milk protein fiber is a fresh product
as a superior green, healthy and comfortable fiber,
which will certainly become popular goods in the
market.
