All

Question 1

Is there a diff in how many points of light can be seen through the greige, mechanically finished, and colored fabric?

Answer 1

Yes, the greige fabric allows more light to go through the fabric.

Question 2

Brushed Fabrics

Answer 2

have a raised fiber surface, similar to napped, density of surface fibers is lower than napped, the yarns have a average twist. Also, more fuzzier than napped

Question 3

Napped Fabrics

Answer 3

relatively thick layer of fibers protruding from their surfaces, and the yarns have a lower twist so it would be easier to pull out the fibers from the yarns in the fabric.

Question 4

Components of a Fabric

Answer 4

1. Fiber Composition
2. Yarn construction
3. Chemicals and finishes
4. Fabric Construction
5. Interstices
6. Colorants
7. Contaminants

Question 5

Perfomance categories

Answer 5

1. durability
2. comfort
3. aesthetic appeal
4. maintenance
5. health/safety/protection

Question 6

Def of property as it pertains to fabric

Answer 6

how the fabric responds to the environment

Question 7

relationship between a fabrics unique combination of components and its properties?

Answer 7

the fabric components will determine the different outcome of the fabric, placing it a unique fabric property and give it a unique performance.

Question 8

does the residue obtained when thermoplastic fibers are removed from the flame reflect the characteristic described in the definition of the thermoplastic fibers?

Answer 8

yes, most of the residues are hard black lumps/beads as opposed to ash since they melted in the flame. and when they were cooled they hardened.

Question 9

what reaction to open flame distinguishes the cellulose fibers from thermoplastic?

Answer 9

the cellulose fibers burn rapidly with afterglow and soft residue and the thermoplastic fibers fuse and shrink away with no afterglow and a hard residue.

Question 10

Why isnt the burning test not suitable for positively identifying the generic names of unlabeled fibers?

Answer 10

It is only suitable to identify the generic groups (cellulose and thermoplastic) because the fibers in each group share similar reactions to flame and would be difficult to differentiate.

Question 11

Major yarn types

Answer 11

spun, filament, compound, fancy

Question 12

Spun

Answer 12

staple fibers held together by some binding mechanism, ring-spun, open-end, and air jet.

Question 13

Filament

Answer 13

composed of single filaments or multiple filaments. continuous filaments assembled with or without twists. Flat, bulk, or stretch yarns

Question 14

Compound

Answer 14

composed of two or more strands, one forming the center, or core, and the other forming the wrap or covering. covered or core-spun yarns.

Question 15

Fancy

Answer 15

Differ significantly from the normal appearance of single or plied yarns die to the presence of irregularities deliberately produced during their formation. could be spiral, corkscrew, gimp, slub, ratine, boucle, thick-and-thin, chenille, loop, snarl, nub, metallic (laminated).

Question 16

Cotton Count

Answer 16

The number of 840-yard lengths of yarn per pound. The smaller the number the larger the diameter

Question 17

Worsted Count

Answer 17

The number of 560-yard lengths of yarn per pound . The bigger the number the larger the diameter

Question 18

Tex

Answer 18

The number of grams per one kilometer lengths of yarn. 1 tex= 1 kilometer

Question 19

Denier

Answer 19

The number of grams per 9000 meter lengths of yarn. 1 denier = 9000 grams
1 tex = 9 denier

Question 20

Decitex

Answer 20

The number of 10 kilometers lengths of yarn weigh one gram. 1 tex = 10 decitex

Question 21

4 Basic fabric construction

Answer 21

1. Woven
2. Knit
3. Non woven
4. Compound

Question 22

Woven

Answer 22

Have two or more sets of yarns interlaced at right angles to each other.

Question 23

Knit

Answer 23

composed of intermeshing loops of yarn

Question 24

Non Woven

Answer 24

composed of webs (batts) of fibers that are entangled or layered

Question 25

Compound Fabrics

Answer 25

composed of two or more layers of fabric or another component held together by stitching, fusing, adhesive bonding

Question 26

Plain Woven

Answer 26

Max number of interlacing.

No technical face or back due to weave (interesting effects with novelty yarns).

Question 27

Balanced Plain Woven

Answer 27

Same number of warp and weft yarns per inch, all the yarns about the same size, same face and back.

Question 28

Unbalanced Plain Woven

Answer 28

Different number of warp and weft yarns.

Regular(same size warp and weft) or Prominent (diff size)

Question 29

Basket Fabrics

Answer 29

Two or more yarns in warp or weft or both in one shed or forms of shed.

Question 30

Types of basket

Answer 30

Full (basket in both directions)

Half (basket in warp or weft)

Question 31

Twill Fabrics

Answer 31

Each warp or filling yarn floats across two or more filling or warp yarns with a progression of interlacing by one to the left or right to form a distinct line.
Forms a distinct diagonal line.
Reg (45) Reclining (15-27) steep (63-75*).
ex. jeans

Question 32

Satin Fabrics

Answer 32

Glossy surface and dull back because it has minimum number of interlacing in a fabric.
‘Satin” filaments
“Sateen” short-staple fibers
