Unit 1: Knowledge about Textile Fibers

It’s important to understand fibers and their performances because fibers are the basic unit

of most fabrics Fibers contribute to the aesthetic appearance of fabrics; they influence durability, comfort and appearance retention;

they influence the care required for fabrics; and they influence the costs Fibers must have

sufficient strength, pliability, length, cohesiveness to be spun into yarns

Unit 1: Knowledge about Textile Fibers

Textile fibers have been used to make cloth for several thousand years Until 1885, when the first manufactured fiber was produced commercially, fibers were produced by plants and animals.The fibers most commonly used were wool, flax ,cotton and silk

Textile process –spinning, weaving, knitting, dyeing and finishing of fabrics were developed for natural fibers

These traditional processes have been modified for manufactured fibers New processes have been developed specifically for manufactured fibers

Fiber properties contribute to the properties of a fabric For example, strong fibers

contribute to the durability of fabrics; absorbent fibers are good for skin – contact apparel

and for towels , flame- retardent fibers are good for children sleepwear protective clothing

1990 cotton met 49% of total world fiber demand

Cotton has a combination of properties –

pleasing appearance, comfort, easy care, moderate cost and durability- that make it ideal for warm-weather clothing; active sportswear; work-cloth; upholstery; draperies; arearugs; towels and bedding

Cotton is an important part of many blended fabrics The cotton spinning and weaving industry began in India

Cotton classification describes the quality of cotton in terms of grade; staple length; and character Fiber length includes short-staple (0.6-2-3cm); medium-staple (2.3 -2.87cm);

long-staple (2.87-3.5cm); extra-long staple (>3.5cm) Grade refers to the color of the fiber

and the absence of dirt, loaf matter, and seed particles The best quality grade is lustrous,

silky, white and clean Color of cotton is ranged from white to yellow Character refers to

maturity and smoothness of fibers within bale

are its body, strength and thick- and-thin fiber bundle which give good texture to fabrics The main limitation of flax is low resiliency Flax has high natural luster, high moisture regain (12%) and is a good conductor of heat , so it makes an excellent fabric of warm-

weather wear

3/ Ramie

Ramie is known as a grasscloth. It has been used for several thousand years in China Ramie is long, lustrous and fine It is one of the strongest natural fibers known But ramie has some disadvantages; it is stiff and brittle,

lacking resiliency Ramie is used to make sweaters, shirts, blouses and suiting It is also

used in blends with cotton, wool to make ropes, nets, auto upholstery, hanknotes, and cigarette paper

Unit 3: Natural Protein Fibers

Unit 3: Natural Protein Fibers

Natural protein fibers are of animal

origin: wool and silk

1/ Wool is one of the first fibers to be

spun into yarns and woven into cloth

Wool was one of the most widely used

textile fiber and now is a luxury fiber The wool legally includes fiber from fur and hair of various animals such as Sheep, Angora goat, Cashmere goat, Camel

Because of its physical structure, wool contributes loft and body to fabrics Wool sweaters, suits, carpets, and upholstery are the standard “looks by which manufactured fiber fabrics are measured Beside drape, luster, and hand, wool fabrics are very durable and high hygroscopic which are the outstanding features of wool

2 / Silk

Silk is a natural protein fiber It is similar to

wool and is produced by the larvae of a moth According to Chinese legend, silkculture or sericulture began in 2640 B.C.when Empress Hsiling Shi became interest in silkworms and learned how to reel the silk and to make it into

fabric Silk is universally accepted as a luxury

Unit 3: Natural Protein Fibers

fiber having a combination of properties not possessed by any other fiber : “ ry tactile hand; Natural luster; High strength; Good moisture absorption; lively draping qualities

Unit 4: Manufactured Fibers

Unit 4: Manufactured Fibers

There are two groups of manufactured fibers: cellulosic and protein The cellulosic

manufactured fibers are more important to the textile industry

1/Rayon

Rayon was the first manufactured cellulosic fiber The developers of rayon were trying to make artificial silk Rayon was originally used

in crepe and linenlike apparel fabrics The high twist that was required to make the crepe yarn reduced the bright luster of the fibers Transparent velvet, sharkskin, tweed, challis and chiffon were also made from these first rayons In 1940, high - tenacy rayon for tyre was developed High – wet - modulus rayon or polynosic rayon is refered to a high-

performance, high-strength rayon which expanded the use of rayon in apparel, home furnishing and industrial products Rayon fibers are highly absorbent, soft, comfortable,

easy to dye, and versatile Fabrics made of rayon have soft drape that designers love Rayon can be made into cottonlike, woolike, silklike fabrics

2/ Acetate

Acetate was the first thermoplastic or

heat-sensitive fiber Acetate is available as staple or filament Acetate is an ester of cellulose and

therefore has a different chemical structure than rayon or cotton Acetate has a combination of properties that makes it valuable textile fiber It is low in cost and has good draping qualities Acetate has been promoted as the beauty fiber It

Unit 4: Manufactured Fibers

is widely used in satins, brocades and taffetas in which luster, body and beauty of fabric are more important than durability or ease of care Acetate keeps white color and that is the advantage over silk which yellows readily A small percentage of nylon may be combined with acetate to produce a stronger fabric Some disadvantages of acetate fabric

are; low breaking tenacity; poor resistance to abrasion; not very resilient and wrinkle during use, lack the easy care Acetate is used in apparel, furnishings and industrial products, however, since acetate is not a durable fiber, the fabric must be carefully selected for the end-use and more cares must be taken during use it

Nylon was the first synthetic fiber and the first

fiber conceived in the United States In 1928, the Du-Pont Company decided to establish a

fundamental research program on high polymers In 1939, nylon 6,6 was introduced

to the public in women’s hosiery Nylon had a

combination of properties: it was stronger,

more resistant to abrasion, excellent elasticity and could be heat-set Besides, due to its high resistance to chemicals, nylon was suitable for ropes, cords, sails, parachutes and other industrial products As nylon entered more end-use markets, its disadvantages became apparent-static built-up, poor hand, lack of comfort in skin contact fabrics, and low resistance to sunlight

Unit 5: Synthetic Fibers

Summary of the performance of Nylon in apparel and furnishing fabrics is shown in following table:

- Aesthetic: Nylon has been very successful in hosiery and in knitted – filament fabrics

such as tricot and jersey because of its smoothness, light weight and high strength The luster of Nylon can be selected for the end – use: it can be lustrous, semi lustrous, or dull

- Durability: Nylon has outstanding durability, suitable for seat – belts, tire, cordssails

- Comfort: Nylon has low absorbency and is not as a comfortable fiber to wear as the natural fibers

- Appearance retention: Nylon fabrics are highly resilient because they have been heat – set. The same process can be used to make permanent pleats, creases, and embossed designs that last for the life of the product Shrinkage resistance is also high because the

heat setting and the low absorbency fiber are not affected by water This excellent

The first polyester fiber, Terylene, was

produced in England It was first introduced

in the U.S.in 1951 by Du-Pont under the

trade name Dacron The outstanding

resiliency of polyester, whether dry or wet,

coupled with its excellent dimensional stability after heat-setting made it an instant favorite Polyester fibers are produced in many types. They may be filament or staple fibers, having high tenacity, low pilling The

fibers are not as transparent as Nylon fibers, but by adding optical whitening chemicals,

they became whiter Polyester’s performance in apparel and furnishing fabrics is summarize in following table:

Properties of Polyester

Properties Importance to customers

Unit 5: Synthetic Fibers

Dimensional stability Machine washable

Resistant to sunlight Good for glass curtains and

draperies

Durable , abrasion resistant Industrial uses, sewing thread

Aesthetic superior to nylon Blends well with other fibers , good

silklike filaments

- Aesthetic: Polyester fibers blend well so that a natural fiber look and texture are

maintained with the advantage of easy care for apparel and furnishings The fabrics look like the natural fiber in the blend Silklike polyesters have been very satisfactory in appearance and hand. Polyester microfibers are particularly suited to high fashion apparel

and furnishing items because of the versatility and durability of the fiber Designers find the microfibers’ drape and hand exciting and challenging Items of microfibers include

coats, suits, blouses, dresses wall – covering, tents, upholstery and toweling.

- Durability: The abrasion resistance and strength of polyester are excellent, their

elongation exceeds that of other fiber 120%

- Comfort: Poor absorbency lowers the comfort in apparel and upholstery Blend of

polyester and cotton are more comfortable even in humid weather. Because of their low

absorbency, polyesters are more electrostatic which is one of the disadvantages of

polyesters

- Appearance retention: Polyester has a high recovery, when small deformations are

involved in wrinkling, polyester recovers better than nylon The dimensional stability of polyester is high Pilling is a severe problem with polyester fabrics
