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

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

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.

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

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

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

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

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

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.

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

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
