Textile Science Final Exam Chapters 6-12

Front 1

Weft Knits

Back 1

Yarn Traverses from side to side (left-right), Interlacing w/ the needles to form new fabric stitches

Front 2

Warp Knits

Back 2

Yarns traverse lengthwise (up-down), interlacing w/ the needles to form new fabric stitches

Front 3

Wales & Courses

Back 3

Ridges in the knit

Front 4

Knit Stitch

Back 4

the basic knitting stitch; also called the plain stitch.

Front 5

Purl Stitch

Back 5

The reverse side of a regular knit stitch. also the back of a jersey knit.

Front 6

Missed Stitch

Back 6

When no stitch is formed, by deactivating one or more needles, and don't move into position to accept the yarn, and the yarn merely passes by

Front 7

Tuck Stitch

Back 7

Formed when knitting needle holds its old loop and then receives a new yarn. Two loops then connect in the needle hook

Front 8

Full-Fashioned Knits

Back 8

A method of shaping a knitted fabric during the knitting process. Full fashioning is popular sweater manufacture.

Front 9

Intarsia

Back 9

When a structure or picture is knitted into the fabric.

Front 10

Dry-laid

Back 10

When non-woven fabrics are made while being dry

Front 11

Wet-laid

Back 11

the material structure is formed by having the fibers manipulated while in a wet state.

Front 12

Spun-laid

Back 12

The material structure is formed by blowing thermoplastic fibers onto a collection surface as the fibers are being extruded.

Front 13

Carded-Web Non-wovens

Back 13

used in disposable items

Front 14

Melt-Blown non-wovens

Back 14

End uses include insulation or outdoor garments & boots.

Front 15

Fusible non-wovens

Back 15

made from thermoplastic fibers or are thermoplastic films

Front 16

Dyeing

Back 16

Dyestuffs, water, mordants
Dyestuffs are highly complex organic substances that combine both chemically & physically w/ an equally complex textile fiber molecule.

Front 17

Pigments

Back 17

Microscopic insoluble colored particles made to adhere to fabric.
Sits on top of fabric.

Front 18

Solution Dyed

Back 18

on Man-made fibers only.

Front 19

Stock-dyeing

Back 19

Refers to the dyeing of fibers, or stock, before it is spun into yarn.

Front 20

Top Dyeing

Back 20

also dyeing of fiber before it's spun into yarn.

Front 21

Yarn Dyeing

Back 21

Dyeing the yarns before they are spun.

Front 22

Cross-dyeing

Back 22

when a yarn fabric or garment made w/ 2 or more generic fiber types having different dye affinities is dyed in a single bath containing 2 different classes of dyes.

Front 23

Union-dyeing

Back 23

Same as cross-dyeing except that one solid color is produced

Front 24

Tone-on-Tone

Back 24

they are light & dark shades of the same color on a fabric containing only one generic fiber

Front 25

Colorfastness

Back 25

dyed/printed textile to resist color loss/fading can't be removed in any of the following ways

Front 26

Color crocking

Back 26

Color comes off dry

Front 27

Color bleeding

Back 27

color comes off wet

Front 28

Direct prints

Back 28

where the design is printed onto a white cloth (un-dyed) or over a previously dyed fabric. Includes yarn dye.

Front 29

Over Prints

Back 29

Printed on dyed fabric.
When the background color is the same shade on the face & back & the print design is substantially darker than the background

Front 30

Discharge Prints

Back 30

When fabric is piece-dyed a solid color, then the fabric design is printed onto the fabric.

Front 31

Resist Prints

Back 31

Batik-when is design in made w/ wax & then dye the fabric using selective dyes that don't require heat.
Tie-dye

Front 32

Pigment prints

Back 32

printing a pattern design on a white fabric w/ a chemical or wax-like substance

Front 33

Blotch Prints

Back 33

where the background color has been created by printing rather than piece dyeing.

Front 34

Flock Prints

Back 34

when tiny particles of fiber are made to adhere to a fabric surface in conformance to a particular design,

Front 35

Warp Prints

Back 35

Printing on warp yarns of a fabric before they are placed on the loom for weaving.
