Unit DMERCHANDISE INFORMATION

4.01 Identify basic textile fibers, fabrics, and their characteristics.

textile industry terms
Textile Industry Terms
  • Fiber: The smallest unit in a textile fabric.
  • Yarn: A group of fibers twisted together to form a continuous strand.
  • Fabric: Any material that is made by weaving, knitting, braiding, knotting, laminating, felting, or chemical bonding.
  • Hand: The way a fabric feels to the touch.
  • Denier: Thickness or diameter of a fiber.
  • Microfibers: Ultra fine, soft, luxurious fibers possessing the same desirable qualities as expensive natural fibers but costing less and requiring less special care.
  • CAD (Computer Aided Design): Computer system software used for designing textiles, fashion, apparel, and other products.
natural fibers
Natural fibers

Fibers from plants or animal sources.

  • Staple fibers: Lower quality, short fibers.
  • Filament fibers: Long, continuous fibers of higher quality.
  • Cellulosic fibers: Fibers from plants.
  • Protein fibers: Fibers derived from animals or insects.
slide4

Manufactured fibers

Fibers that are man-made (synthetic) and are created by combining various substances with chemicals.

  • Solid raw materials and chemicals are melted or dissolved to form a thick liquid.
  • The liquid is forced through the tiny holes of a mechanical device known as a spinnerette to form filaments. (Similar to pushing dough through a pasta machine to make spaghetti.)
  • The filaments are then stretched, hardened, and crimped and/or cut into lengths.
slide5

Manufactured fibers (cont.)

  • Cellulosic manufactured fibers are made from cellulose from plants such as soft wood pulp and are changed into usable fibers by applying chemicals.
  • Noncellulosic manufactured fibers are made from various petrochemical mixtures of crude oil, natural gas, air, and water.
slide6

Blend: A combination of two or more fibers that maximizes the best features of each fiber.

  • Example: Combining cotton with polyester

steps involved in fabric production
Steps involved in fabric production
  • Fibers are usually twisted together and spun into yarns.
  • Yarns are either woven or knitted to form fabric.
  • Color is added by dyeing or printing to enhance the fabric’s appeal.
  • A finish is applied to make the fabric suitable for its end use and to improve its appearance.
turning yarn into fabric
Turning Yarn into Fabric

Weaving: The process of interlacing one or more sets of yarns at right angles on a loom.

  • Warp yarns: Yarns that run lengthwise in woven fabric.
  • Weft yarns: Yarns that run crosswise in woven fabric.
turning yarn into fabric cont
Turning Yarn into Fabric (cont.)
  • Grain: The direction of the lengthwise and crosswise yarns or threads in a woven fabric.
  • Bias: The diagonal grain of a fabric. The bias provides the greatest “give” or stretch in the fabric.
weaving
Weaving
  • Plain weave: The simplest weave in which the weft (crosswise) yarn is passed over then under each warp (lengthwise) yarn.
    • A basket weave is one variation, with the weft yarn passing over two and under two warp yarns each pass.
    • Examples: Chiffon, seersucker, taffeta

Plain weave

weaving1
Weaving
  • Twill weave: A weave in which the weft yarn is passed over and under one, two, or three warp yarns beginning one warp yarn back on each new row.
    • Used for durability, this weave produces a diagonal design on the surface.
    • Examples: denim, gabardine

Twill weave

weaving2
Weaving
  • Satin weave: A weave that produces a smooth, shiny-surfaced fabric resulting from passing the weft yarn over and under numerous warp yarns to create long floats.
    • Examples: sateen, satin

Satin weave

Weaving

Other weaves

  • Pile weave—corduroy, velvet
  • Dobby—dotted swiss, pique
  • Jacquard—brocade, damask
  • Leno—fabrics with an open, lacy appearance
knitting
Knitting

Weft knits: Knits made with only one yarn that runs crosswise forming a horizontal row of interlocking loops.

Cut edges will curl.

Weft knits run if snagged.

Examples: jersey, ribbed knits, sweater knits

Constructing fabric by looping yarns together.

knitting cont
Knitting (cont.)

Warp knits: Knits made with several yarns creating loops that interlock in the lengthwise direction.

Do not ravel

Have selvage edges

Examples: tricot, raschel knits

Gauge: The number of stitches, or loops, per inch in a knitted fabric.

additional ways to construct fabric
Additional ways to construct fabric
  • Nonwoven. Fibers are compacted together using moisture, heat, chemicals, friction, or pressure. Examples: quilt batting, garment interfacings, felt, artificial suede
  • Laces and nets. Made by knotting, twisting, or looping yarns. Example: lace
  • Braided fabrics. Created by interlacing three or more yarns to form a regular diagonal pattern down the length of the resulting cord. Examples: decorative trims, shoelaces
  • Bonded fabric. Made by permanently fastening together two layers of fabric by lamination. Examples: two fabrics bonded so that one serves as a self-lining as in skiwear or winter coats
additional ways to construct fabric cont
Additional ways to construct fabric (cont.)
  • Quilted fabric. A layer of padding or batting is sandwiched between two layers of fabric and held in place by stitching. Examples of use: bedspreads, placemats, and outerwear
fabric finishing
Fabric finishing

Applying colors, designs or surface treatments that change the look, feel, or performance of fabrics.

  • Bleaching: Chemical processes that remove color, impurities, or spots from fibers.
  • Dyeing: A method of giving color to a fiber, yarn, fabric, or garment.
  • Printing: The process of adding color, pattern, or design to the surface of fabrics.
finish categories
Mechanical: Finishes that are applied mechanically rather than chemically.

Affect size and appearance

Examples: glazing, embossing, brushing/napping/cutting (corduroy)

Chemical: Finishes that become part of the fabric through chemical reactions with the fibers.

Affect performance

Examples: flame retardant, stain resistant (Scotchgard®), waterproof, permanent press, preshrunk (Sanforized®)

Finish categories
equipment and machinery
Equipment and machinery
  • More automated weaving and knitting machines
  • Color management tools that can synchronize a colored design on a computer screen, a paper printout, and the actual fabric color
  • Sophisticated CAD tools with 3D capabilities
  • Processes constantly monitored by computer systems

Government regulations

  • The Wool Products Labeling Act (1939) provides that all garments made of wool have a label indicating the percentage and kind of wool used.
  • The Textile Fiber Products Identification Act (1958) requires that all clothing have a label listing the generic fiber content by percentage.
  • The Flammable Fabrics Act (1953) regulates the sale of highly flammable fabrics used in apparel and prohibits the sale of extremely flammable fabrics.
  • The Permanent Care Labeling Act (1972) requires that all clothing offered for sale in retail stores have a label indicating specific care instructions. New symbols for use in this labeling were introduced in 1997.
