  1. 1. Fabric Studies01/18/13 Fabric Styling - Neha Singh
  2. 2. Fiber structure Physical attributes• Fiber length• Staple fibers• Filament fibers- silk• Fiber shape- fiber cross-sectional shape influences the way light is reflected from the surface. A flat surface fiber has more luster than a round one. A round fiber reflects light is one general direction, causing a shiny surface.• A multi lobal shaped fiber tends to scatter the light, causing the diffuse glow with sparkles.• Irregular cross-section scatters light in many directions, resulting a dullish appearance..01/18/13 Fabric Styling - Neha Singh
  3. 3. • Fiber surface- The surface of fiber vary.• Smooth, rough, slightly grooved, wrinkled etc.• The fiber surface affects such as properties as hand, luster and wicking• Fiber Longitudinal Configuration• Lengthwise, fibers have varying configurations. They may be straight, twisted, coiled, or crimped. Exp cotton and nylon.• Various properties like resiliency, elasticity and abrasion resistance are affected by fiber longitudinal configuration.01/18/13 Fabric Styling - Neha Singh
  4. 4. • Greater crimp increase resiliency, bulk, warmth, elongation, absorbency and skin comfort.• However , hand becomes harsher and luster is reduced as crimp increases• Crimp allows the fiber to stand off the skin so fabric will not cling to the wearer skin.• Crimp is inherent in the wool fiber.• Fiber Diameter• Fiber diameter refers to the thickness of the fiber. Thicker fibers result is greater stiffness, which improves wrinkle resistance but can also result in an undesirable roughness.• Large diameter fibers result in bulkier fabrics. Fine diameter fibers can result in fabric that is sheer, lightweight and generally more drapable and softer to the touch than the fabric of thicker fibers.01/18/13 Fabric Styling - Neha Singh
  5. 5. • Chemical composition and molecular formation• fibers are classified into various groups by their chemical composition:• Cellulosic, protein and synthetic01/18/13 Fabric Styling - Neha Singh
  6. 6. Essential properties• Abrasion Resistance- is the ability to resist wear from rubbing that contributes to fabric durability.• Exp- Nylon is used extensively in action outerwear, such as ski jackets , and soccer shorts, because it is very strong and resist abrasion .01/18/13 Fabric Styling - Neha Singh
  7. 7. • Absorbency – Absorbency is the ability to take in moisture.• Fibers able to absorb water easily are called hydrophilic fibers.• Hydrophilic fibers- all natural animal and vegetable fibers and two manufactured fibers, rayon and acetate.• Hydrophobic fibers- fibers that have difficulty absorbing water and are only able to absorb small amounts .• Skin comfort, Static build-up, dimensional stability in water, stain removal, water repellency, wrinkle recovery01/18/13 Fabric Styling - Neha Singh
  8. 8. • Cover- cover is the ability to occupy an area. A thick fiber or one with crimp or curl gives fabric better cover than a thin, straight fiber.• Elasticity- is the ability to increase in length when under tension (elongation ) and then return to the original length when released (recovery)• Lengthening when tension is placed on the fiber or fabric makes for a more comfortable garment and causes less seam stress.01/18/13 Fabric Styling - Neha Singh
  9. 9. • Environmental conditions- the effect of environmental conditions on fibers vary. How fabrics react to certain exposure or storage , is important. The following are some examples-• Wool garments needs to be mothproofed when stored because they are susceptible to damage by these wool eating insects.• Nylon and silk show strength losses from extended exposure to sunlight. Therefore , they are normally not used for curtains and drapes.• Cotton has poor resistance to mildew and should not be allowed to remain wet for long periods of time.01/18/13 Fabric Styling - Neha Singh
  10. 10. • Flammability- is the ability to ignite or burn.• Fibers are usually classified as being flammable flame resistant , or flameproof.• Flammable fibers- are relatively easy to ignite and sustain combustion.• Flame-resistant fibers- have a relatively high ignition temperature and slow rate of burning .• Flame proof fibers- will not burn.• Regular polyester is flammable , but Trevira polyester , which is flame resistant.01/18/13 Fabric Styling - Neha Singh
  11. 11. • Flexibility- is the capability of fibers to bend easily and repeatedly without breaking.• Hand- is the way a fiber, yarn or fabric feels when handled. The hand of the fiber is affected by its shape, surface and configuration .• Luster- refers to the light reflected from a surface. Various characteristics of a fiber effect the amount of luster.• Increased light reflection occurs from a smoother surface, less crimp, flatter cross sectional shape and longer fiber length.• Pilling- is the formation of groups of short or broken fibers on the surface of a fabric that are tangled together in the shape of tiny ball called pill.• Resiliency- is the capability of a material to spring back to shape after being creased, twisted or distorted.• A fabric that has good resiliency does not wrinkle easily01/18/13 Fabric Styling - Neha Singh
  12. 12. • Specific gravity- is the ratio of the mass of the fiber to an equal volume of water at 4degree c .• Static Electricity- is a frictional electric charge caused by the rubbing together of two dissimilar materials.• Strength- is a fiber’s ability to withstand stress.• Tenacity- the force needed to break the fiber, is known as tenacity and expressed in grams per denier or grams per fiber weight.• Glass, Nylon and Polyester are very strong. Acetate and acrylic are weak.01/18/13 Fabric Styling - Neha Singh
  13. 13. • Thermo plasticity- the ability of fibers to withstand heat exposure is an important factor affecting their suitability for many end uses.• Wicking- is the ability of fiber to transfer moisture from one section to another. Usually the moisture is along the fiber surface, but it may also pass through the fiber when a liquid is absorbed by the fiber.01/18/13 Fabric Styling - Neha Singh
