Answer 3

강도

Ability to withstand rupture

Question 4

Breaking tensile strength

Answer 4

인장강도

Ability to withstand longitudinal pulling force without rupture (길이 방향으로 당기는 힘) - 옷이 절단될때에 하중)

Question 5

Tearing strength

Answer 5

인열강도

Ability to resist further rupture when lateral pulling force is applied at hole/cut (측면 방향으로 옷이 찢어지는 힘)

Question 6

Bursting strength

Answer 6

파열강도

Ability to retain physical integrity when a perpendicular swelling force is applied 수직으로 부푸는힘 -> 파열될때 강도

신도>강도 - 영향을 줌
작은 인장강신도가 높은 인장강신도쪽으로 찢어짐

Question 7

Elongation at break

Answer 7

파단시 신도

Ability to extend when subjected to mechanical forces

인장강신도 측정 직물, 부직포, 펠트 많이 함
편성물x

Question 8

Stress strain graph

Answer 8

하중-신장 곡선

Y= 강도
X= 신도

I.m= y/x

I.m 낮으면 - 유연
I.m 높으면 - 강인

Question 9

Ability to return to its original dimensions after being elongated/stressed

Question 11

마모

Answer 11

Abrasion

마찰, 굴곡, 파괴, 절단에 의한 옷의 퇴화

Question 12

Abrasion resistance

Answer 12

마모강도/내마모성

Ability to withstand rubbing (friction) force

1) 마찰횟수 until hole forms
2) 무게변화

Question 13

마모강도 종류

Answer 13

평면마찰 - flat abrasion - planar surface
단마찰 - edge abrasion - folded edge
굴곡마찰 - flex abrasion- unidirectional bending

Question 14

Chimney effect

• 자연대류
• 하개구부 -> 상개구부

Question 21

풀무효과

Answer 21

Below effect

• 강제대류
• 하개구부만 존재 so 따뜻한 바람 맡으로 나감

Question 22

인체움직임 쾌적성

Answer 22

Body movement comfortability

Ability to allow freedom of movement

Question 23

Insulative ability

Answer 23

단열성능

Degree of resistance to heat transfer

• fabric acts as barrier -> low conductivity
• slows rate of convective heat loss
  -> trap air in interstices (공극) -> dead air 정지공기층
• thicker the fabric -> higher resistance

Question 24

Water vapor permeability

Answer 24

투습성

Rate of diffusion of body vapour through fabric

• type of fiber (친수성/소수성)
• 기공도 (size of 기공/공극)

Question 25

Wickability

Answer 25

심지흡수력 Dispersion of water in given area horizontally/vertically by wicking/capillary action Occur outside of fibers through interstices

Question 26

쾌적성의 종류

Answer 26

1. Sensorial comfort 감각 쾌적성 2. Body movement comfort 인채 움직임 쾌적성 3. Insulation ability 단열성능 4. Wickablilty 심지흡수력 5. Water vapor permeability 투습성 6. Water content/regain 수분함량 7. Drying rate 건조속도 8. Water repellency 발수성 9. Water resistance and water proofness 물저항성 방수성

Question 27

Water resistance and water proofness

Answer 30

물저항성 + 방수성 - resistant to water droplets but permeable to water vapor (sweat) - ability to resist wetting and penetration of h2o
