1. 2.01 Understanding The Technical Design Process of how fabric is made
A. Fabric Selection
1. Fabric Construction

2. Turning ______ into ___________
_______: The process of interlacing one or more sets of yarns at right angles on a loom.
_____ yarns: Yarns that run lengthwise in woven fabric.
(“p” = up and down)
______ yarns: Yarns that run crosswise in woven fabric.
(“weft” sounds like left & right)
Show example of selvage edge in relation to ward and weft

3. Turning Yarn into Fabric (cont.)
Grain: The _________of the lengthwise and ________ yarns in a woven fabric.
Bias: The ________ _______of a fabric. The bias provides the greatest _________ in the fabric.
Use example to show grain and bias.

4. Weaving
Plain weave: The simplest weave in which the weft (crosswise) yarn is passed over then under each warp (lengthwise) yarn.
A basket weave is one variation, with the weft yarn passing over two and under two warp yarns each pass.
PLAIN WEAVE
Use magnifying glass to examine examples of weaves.
Examples: chiffon
gingham seersucker taffeta

5. Weaving
Twill weave: A very strong weave in which the weft yarn is passed over and under one, two, or three warp yarns
Used for durability, this weave produces a diagonal design on the surface.
Twill weave
Examples: denim, chino
gabardine

6. Weaving
Satin weave: A very weak weave that produces a smooth, shiny-surfaced fabric resulting from passing the weft yarn over and under numerous warp yarns to create long floats.
Satin weave
Examples: sateen
satin

7. Weaving In ____________, pile is the raised
surface or ______of a fabric, which
is made of upright loops or
strands of ___________

8. Weaving
A pile weave is made on a ________, like most types of weaves are made. The difference is that __________ are created.
These loops can either be left uncut, like in towels, or can be cut to uniform ___________, like in velvet fabric.
Types of fabrics created using a pile weave include __________, Corduroy, Terrycloth, and Velveteen

9. Weaving Assignment
Using construction paper cut into strips about 1 inches x 11 inches you should recreate:
plain weave
twill weave
satin weave
On the back of each weave:
list the advantages
list disadvantages
3 examples of weave
Describe weaving assignment.

10. Turning Yarn into Fabric
___________: the process of pulling loops of yarns through other _________ to create interlocking rows of stitches
Wales – yarns that run in the __________ direction , like a warp yarns in woven fabrics
Courses – yarns that run in the ________ direction, like the weft yarns in woven fabrics

11. Knitting ________ Knit: a knit made with only one yarn
Types of weft knits include:
Jersey knits – most common type, curls at edges, used for t-shirts, sweaters and tights/hosiery
Rib knits – have vertical “ribs” (columns of stitches), used for neck, wrist and bottom bands of sweatshirts & jackets
Double knits – two yarns and two needles are used resulting in heavier, sturdier knits that don’t run or ravel
Characteristics include:
Two-way stretch in both lengthwise & crosswise directions
Can get lengthwise “runs” from broken threads
Made on either flat or circular knitting machines

15. Knitting
____________ knit: a knit made with several yarns on flat knitting machines. Multiple yarns are looped together to produce a run-resistant knitted fabric.
___________ knits – stable knits that lie flat and don’t run or ravel, made on very fast tricot knitting ____________, used for lingerie, underwear and uniforms
Raschel knits – an extra yarn is used to create a ____________ design in these knits, used for lacy knits, thermal underwear and bathing suits

16. Knitting
Tricot knits

17. Knitting
Raschel knits

18. Knitting _____________ knitting involves the production
of a whole garment in
__________ piece on a knitting
machine so that little
or no sewing is required.

19. Nonwoven Fabrics Made from _________, not yarns
Fibers are held together by a combination of moisture, heat, chemicals and/or pressure.
No __________line
Limited stretch
