Chapter 2

Question 1

Crimp

Answer 1

waves in the fiber

Question 2

staple fiber

Answer 2

less than 1in to 18 in long

Question 3

filament fiber

Answer 3

indefinitely long and measured in yards to even miles

Question 4

cross section

Answer 4

appearance of the fiber across its diameter

Question 5

surface contour

Answer 5

appearance of the outside of the fiber

Question 6

diameter

Answer 6

width of the cross section

Question 7

covering power

Answer 7

ability of fabric to hide what is beneath it

Question 8

hand/texture

Answer 8

the feel of the fiber

Question 9

luster

Answer 9

the amount of light reflected from fiber

Question 10

abrasion resisitance

Answer 10

ability of fiber to withstand effects of rubbing or friction

Question 11

pilling

Answer 11

result of abrasion;little balls that form on surface of fabric

Question 12

dimensional stability

Answer 12

ability of fiber to maintain original shape, neither shrink or stretch

Question 13

elastic recovery

Answer 13

ability of fiber to return to its original length after it is stretched

Question 14

elongation

Answer 14

the act of lengthening or stretching fiber

Question 15

drape

Answer 15

ability of fiber to hang in graceful manner

Question 16

body

Answer 16

resistance of fabric to its own weight and be stiff and lift away from contours of body;drape and body cannot exist simulataneously in a fabric

Question 17

resiliency/wrinkle recovery

Answer 17

ability of fiber to return to its original shape after being bent or folded

Question 18

tenacity

Answer 18

fiber strength, important for life of textile

Question 19

wicking

Answer 19

fibers ability to carry moisture to the surface to evaporate; the fabric has both hydrophobic and hydrophilic properties

Question 20

hydrophilic

Answer 20

absorb moisture, slow dry

Question 21

hydrophobic

Answer 21

do not absorb moisture

Question 22

hygroscopic

Answer 22

absorb moisture but dont feel wet

Question 23

electrical conductor

Answer 23

doesnt hold electrical charge

Question 24

electrical retainer

Answer 24

holds onto charge

Question 25

acid sensitivity

Answer 25

how well a fiber can resist imapct from acid

Question 26

base sensitivity

Answer 26

how well fiber can resist damage from base; bases damage protein fibers

Question 27

oxidizing agents

Answer 27

bleach damages protein fibers; safe on synthetic and cotton

Question 28

thermoplastic

Answer 28

fibers that melt or soften when exposed to heat; synthetics get damaged

Question 29

heat setting

Answer 29

changing shape of fibers; this is imortant for textile products that need dimensional stability so that the shape doesnt disappear when you iron it out for example

Question 30

fireproof

Answer 30

no impact by fire

Question 31

flame resistant

Answer 31

ignites in open flame but does not continue to burn when removed from flame

Question 32

flammable

Answer 32

will ignite and stay burning

Question 33

noncombustible

Answer 33

won't burn but can melt and decompose

Question 34

self extinguishing

Answer 34

will stop burning when moved away from flame; characteristic of flame resistant

Question 35

thermal stability

Answer 35

will not burn or shrink when exposed to flame
