formed into sheets, extruded in a molded form, or applied as a coating
- heavy
- high resistance to heat and chemicals
- resistant to sunlight, weathering, aging

Term
|
Definition

|
Term
|
Definition
| a continuous strand of textiles fibers, filaments, or materials in a form suitable for knitting, weaving, or otherwise intertwining to form a textile fabric |
|
|
Term
Filament yarns
definition
|
|
Definition
made from manufactured fibers, except for the tiny percentage that is filament silk
made from extruding a polymer solution through a spinneret and solidifying it in fiber form and individual filaments are brought together with a slight twist |
|
|
Term
Smooth filament yarns
def. and characteristics |
|
Definition
uniform bc they come from a spinneret
- smooth, high luster
- no protruding ends (no lint)
- resist pilling
- shed soil
- round cross-sections=more compact
- non-round cross-sections= more open space for air and moisture permeability and greater cover
- strength depends on indiv. filaments and # of them
- filaments have low twist -> only 3-6 turns/inch
|
|
|
Term
|
Definition
- primarily used for industrial stuff
- made of single coarse-filament fiber
- used for hemming less-expensive products (lower-end comforters)
|
|
|
Term
Bulk Yarns
def.,characteristics, & uses |
|
Definition
- been processed to have greater covering power or apparent volume than an equal conventional yarn
- often referred to as BCF (bulk-continuous-filament)
- gives man-made yarns a more natural appearance
- alter surface characteristics and create more space b/t fibers
- lowers static buildup
|
|
|
Term
| Texturing filament yarns for stretch |
|
Definition
process of adding stretch to yarns and/or modifying yarn surfaces
- false twist
- knife edge or edge crimping
- gear crimping
|
|
|
Term
|
Definition
yarn is twisted, heat set, and untwisted as it travels through a spindle
- widely used, cheapest
- resembles crepe yarns
|
|
|
Term
| Knife edge/Edge Twist Process |
|
Definition
- heated filaments drawn over an edge
- flattens one side causing yarn to curl (like ribbon on a present)
|
|
|
Term
|
Definition
- yarn passes through 2 sets of heated gears
- not used frequently
|
|
|
Term
|
Definition
- creating yarn with more bulk or loft
- yarn cannot lie as close to each other

Term
|
Definition
Texturing for Bulk
- stuff filament yarns into a heated chamber
- when they are removed, they're crimped
- fast, inexpensive, and widely used
|
|
|
Term
|
Definition
Conventional filament yarns are fed over an air jet at a faster rate than they are drawn off. The blast of the air forces some of the filaments into very tiny loops
- slow, expensive
- yarns maintain size and bulk under tension
|
|
|
Term
|
Definition
small diameter tube is knit, heat-set, unraveled, and wound on cones
- yarn retains looped form
- Ex: panty hose

|
Term
Tape Yarns
def & characteristics |
|
Definition
made when films, or thin sheets of polymer, are extruded and then slit into narrow tapes
|
|
|
Term
|
Definition
carpet backing
rope
cord
fishnets
bagging
|
|
|
Term
Spun Yarns
def & characteristics |
|
Definition
continuous strands of staple fibers held together by some mechanism (often mechanical twist)
- have fuzzy protruding ends compared to filament yarns
- have to have higher twist to hold them together
- pull apart when untwisted
- produce them by: traditional/ring spinning. open-end rotor spinning, air-jet
