WeavingWeaving: The : The process of process of interlacing one or interlacing one or more sets of yarns more sets of yarns at right angles on a at right angles on a loom.loom.
Warp yarns: Yarns that run lengthwise in woven fabric.
Weft yarns: Yarns that run crosswise in woven fabric.

Turning Yarn into Fabric Turning Yarn into Fabric (cont.)(cont.)
Grain: The direction of the lengthwise and crosswise yarns or threads in a woven fabric.
Bias: The diagonal grain of a fabric. The bias provides the greatest “give” or stretch in the fabric.

WeavingWeaving
Plain weave
Plain weave: The simplest weave in which the weft (crosswise) yarn is passed over then under each warp (lengthwise) yarn. Examples: Chiffon, seersucker, taffeta
A basket weave is one variation, with the weft yarn passing over two and under two warp yarns each pass.Example: oxford cloth

WeavingWeaving Twill weave: A weave in which the weft yarn is passed over and under one, two, or three warp yarns beginning one warp yarn back on each new row.
Used for durability, this weave produces a diagonal design on the surface.Examples: denim, gabardine

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

Fiber dyeing
natural fibers are dyed before they are spun into yarns. Allows for colorful yarns; (solution dyeing for manufactured)

Yarn Dyeing
yarns are dyed before weaving (used for plaids, checks, stripes)

Piece Dyeing
fabric is woven or knitted and then dyed

Garment Dyeing
fabric is cut and sewn in to the finished product, then dyed

Printing designs onto fabric
Roller printing: one plate for each color of the design (raised and low areas for color or no color)

Screen printing
mesh fabric is stretched over a frame, design is “burned” onto the fabric, colors are pressed through the mesh onto the fabric (large designs are best)

Rotary Screen Printing
combines screen and roller; faster than screen cheaper than rollers

Heat Transfer Printing
printed onto paper first, then heat set onto the fabric
(think t-shirts on the spot)
