Nylon Fibers Most nylon manufactured today is nylon 6.6, a chemical composition that was developed by DuPont in 1935. A thermoplastic material, the fiber is produced by combining equal parts diamine and dicarboxylic acid, which react and create nylon salt. This compound is high in carbon, hydrogen and nitrogen. The salt is heated and dehydrated to form the polymer, which is melted and spun to create the nylon fiber. Rayon Fibers One of the major differences between nylon and rayon is their chemical makeup. Rayon is made from organic matter. A cellulose fiber, meaning it's derived from wood, rayon is made from a high-grade wood pulp called "dissolving cellulose." The pulp is refined with a caustic soda or lye solution before it's streamed through a spinneret, a device that resembles a shower head. The fibers solidify in an alkali-based bath to produce fine silken fibers

9. INTRODUCTION ABOUT NYLONE
• First created by William Carother, a
Lecturer from Harvard University, in
1934 at DuPont Company research lab
• DuPont scientist created Nylon 6.6
• German scientist created Nylon 6
• Second most used fiber in the U.S.A
• First used in a nylon toothbrush
Nylon is a generic designation for a family of synthetic
polymers, based on aliphatic or semi-aromatic polyamides.
Nylon is a thermoplastic silky material[1] that can be melt-
processed into fibers, filmsor shapes.

This polymer is called nylon 6.6 because each of these
components chemical compounds (hexamethylene
diamine and adipic acid) contain 6 carbon atoms per
molecule

25. VISCOS
• Viscose is a semi-synthetic fiber. "Viscose" can mean:
• A viscous solution of cellulose, which can be made into
rayon or cellophane
• A synonym for rayon
• A specific term for viscose rayon—rayon made using
the viscose (cellulose xanthate) process
• The viscose process dissolves pulpwith aqueous sodium
hydroxide in the presence of carbon disulfide. This
viscous solution bears the name viscose. The cellulose
solution is used to spin the viscose rayon fiber, which
may also be called viscose. Viscose rayon fiber is a soft
fiber commonly used in dresses, linings, shirts, shorts,
coats, jackets, and other outerwear. It is also used in
industrial yarns (tyre cord), upholstery and carpets, and
in the casting of cellophane.

26. MONOMER
• Viscose rayon is a fiber of regenerated cellulose; it is
structurally similar to cotton but may be produced from a
variety of plants such as soy, bamboo, and sugar cane.
Cellulose is a linear polymer of β-D-glucose units with the
empirical formula (C6H10O5)n.[2] To prepare viscose, dissolving
pulp is treated with aqueous sodium hydroxide (typically 16-
19% w/w) to form "alkali cellulose," which has the
approximate formula [C6H9O4-ONa]n. The alkali cellulose is
then treated with carbon disulfide to form sodium
cellulose xanthate.[3]
• [C6H9O4-ONa]n + nCS2 → [C6H9O4-OCS2Na]n

27. • Rayon fiber is produced from the ripened solutions by
treatment with a mineral acid, such as sulfuric acid. In this
step, the xanthate groups are hydrolyzed to regenerate
cellulose and release dithiocarbonic acid that later
decomposes to carbon disulfide and water:[5]
• [C6H9O4-OCS2Na]2n + nH2SO4 → [C6H9O4-OH]2n +2nCS2 +
nNa2SO4
• H2COS2 → H2O + CS2

RAYON

31. MANUFACTUER

32. When a solution of cellulose in
cuprammonium hydroxide comes into
contact with sulfuric acid, the cellulose
begins to precipitate from the solution.
The sulfuric acid reacts with a complex
compound of copper and dissolves it.
Thin blue fibers of rayon are formed. After
some time, sulfuric acid reacts with the
complex compound and washes out the
copper salts from the fibers. The fibers
become colorless.

34. • Rayon or artificial silk is a manufactured regenerated cellulose
fiber.
• It is made from purified cellulose, primarily from wood pulp, which
is chemically converted into a soluble compound. It is then
dissolved and forced through a spinneret to produce filaments
which are chemically solidified, resulting in synthetic fibers of
nearly pure cellulose.[1]
• Workers can be seriously harmed by the carbon disulfide used to
make most rayon.[2][3]
• Because rayon is manufactured from naturally occurring polymers,
it is considered a semi-synthetic fiber.[4] Specific types of rayon
include viscose, modal and lyocell, each of which differs in
manufacturing process and properties of the finished product.

35. PROPARTIES

36. • The durability and appearance retention of regular viscose
rayon are low, especially when wet; also, rayon has the
lowest elastic recovery of any fiber. However, HWM rayon
(high-wet-modulus rayon) is much stronger and exhibits
higher durability and appearance retention. Recommended
care for regular viscose rayon is dry-cleaning only. HWM
rayon can be machine washed.[10]
• Rayon industrial yarns outperform polyester and are
produced for belts in high performance tires (e.g. Cordenka,
Germany).

38. USES OF VISCOSE RAYON

39. • Rayon is a versatile fiber and is widely claimed to
have the same comfort properties as natural fibers,
although the drape and slipperiness of rayon
textiles are often more like nylon. It can imitate the
feel and texture of silk, wool, cotton and linen. The
fibers are easily dyed in a wide range of colors.
Rayon fabrics are soft, smooth, cool, comfortable,
and highly absorbent, but they do not insulate body
heat, making them ideal for use in hot and humid
climates, although also making their "hand" (feel)
cool and sometimes almost slimy to the touch
