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.

4
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.

5
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.

6
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.

7
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

1. Fibers are usually twisted together and spun into
   yarns.
2. Yarns are either woven or knitted to form fabric.
3. Color is added by dyeing or printing to enhance
   the fabrics appeal.
4. A finish is applied to make the fabric suitable
   for its end use and to improve its appearance.

29
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.

30
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.

31
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
32
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
33
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
34
Weaving

• Other weaves
• Pile weavecorduroy, velvet
• Dobbydotted swiss, pique
• Jacquardbrocade, damask
• Lenofabrics with an open, lacy appearance

35
Knitting
Constructing fabric by looping yarns together.

• 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

36
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.

37
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

38
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

39
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.

40
Finish categories

• 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)

• Mechanical Finishes that are applied
  mechanically rather than chemically.
• Affect size and appearance
• Examples glazing, embossing, brushing/napping/cu
  tting (corduroy)

41
Fabric Characteristics

• Instructions Choose 2 different fabric
  samples

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.
