TAM EXAM (ch 14-16) QUESTIONS
AND ANSWERS19
tentering - ANSWERS -applies crosswise and lengthwise tension to fabric while it dries.
Eliminates problems of skewing and bowing.
-look at the selvage edge
-keeps fabric on-grain
reworking - ANSWERS -includes inspecting fabric for defects or flaws and repairing problems
wherever possible
fabric inspecting - ANSWERS -moving fabrics over an inverted frame in good light
repairing - ANSWERS -flaws repaired when possible
knitting - ANSWERS -the formation of a fabric by inter-looping of one or more yarn sets
-newer technique
-4x greater than loom for weaving
-requires more yarn than woven fabrics
-porous, bulky, lofty, warm, wrinkle resistant, comfortable, good appearance retention, low in
cover, permeable, stretchy
-may run or snag (collapse of wale)
-more prone to shrinkage than woven fabrics
-counterpart can be woven
-DO NOT move in both directions like weaving
,knits are usually made with - ANSWERS -one yarn set
2 methods of knitting - ANSWERS -1) filling (weft)
2) warp
filling knitting - ANSWERS -Knit where one yarn or yarn set is carried back and forth or around
and under needles to form fabric yarns moved horizontally
-can be made by hand or machine
warp knitting - ANSWERS -yarn moves vertically in the fabric
when a woven fabric is unraveled - ANSWERS -both warp and filling yarns are removed
when knit fabric is unraveled, - ANSWERS -ONLY a row of loops is removed
knits can be classified by: - ANSWERS -1) machine its made from
2) # of yarn sets in the knit
3) type of stitch or stitches used
4) type of fabric produced
most filling knits are used with a - ANSWERS -latch needle
spring beard needle - ANSWERS -knitting needle that may be used to produce fully fashioned
garments, fleece, and fine yarn fabrics
double-latch needle - ANSWERS -used to make purl fabrics
, compound needle - ANSWERS -needle used primarily in warp knitting
stitches - ANSWERS -yarns manipulated by needles
-names based on way they are made
-may be open or closed
-open stitches are most common in filling knitting
-open and closed used in warp knitting
fabric characteristics of knitting - ANSWERS --type of knit
-fabric density
-can be hard to locate technical face and back
fabric density - ANSWERS -defined by counting the number of stitches, not yarns, in a specific
direction
wale - ANSWERS -vertical columns of stitches in the knit fabric
course - ANSWERS -horizontal rows of stitches
guage - ANSWERS -indicates fineness of stitch
-expressed in needles per inch (npi)
-higher the guage, the finer the fabric
technical face - ANSWERS -the outer side of the fabric as knitted
-may not be fashion side in product
-better finish
