background image EXAM 2 Study Guide Fall  2018 The exam covers chapters 6-14 and will have both multiple-choice 
questions and visual and vocabulary matching sections.  
Weaving 1. Warp a. Yarns running parallel to selvage
b. Lengthwise grain
c. Stronger
2. Weft a. Yarns running perpendicular to selvage
b. Crosswise grain
3. How fabric is made by weaving a. Warp yarns are threaded onto heddles attached to loom harnesses
b. Harnesses are then lifted in various sequences to create a space called
the shed c. The weft yarn is fed through this shed
d. As harnesses are raised and lowered, yarns interlace
e.
4. What is a loom? a. It is how the yarns are woven together in a machine to make a piece of fabric Fabric Weight and Cover Heavier o Stiffer
o Better durability
o More fiber
Lighter  o Better drape
o Softer
o Less fiber
Extremely light or sheer weight o Sheer or gauzy fabrics Light or top weight o Blouses, shirting, light dresses Medium weight o Heavier shirting, lighter bottoms Bottom weight o Slacks, suiting, lighter jackets Heavy weight o Work clothes, heavier coats, traditional denim How do weight and cover affect final properties and appropriate end use? 
background image EXAM 2 Study Guide Fall  2018 Thread Count
What is thread count? 
Density (#) of yarns/square inch Count = total of both warp and weft directions How does a high or low thread count affect end use and hand? Higher thread count o Smoother hand 
o Better drape
o Better dimensional stability
Lower thread count o Less durable
o Poor drape
What is the difference between balanced and unbalanced thread count? a. What texture do unbalanced weaves create in the fabric?
b. How does it affect drape?
2. Which kinds of weaves are more likely to have higher thread count? How  does yarn type affect thread count? 3. Plain and Twill, thinner or filament yarns will have a higher thread count Weave Types (Plain vs. Twill vs. Satin) Know major types and how to identify each category. What are their construction 
differences, ‘stand out’ properties, and appropriate end uses?
Plain Weave
1. Most common
2. Least expensive woven fabric
3. Varied end uses across all categories
4. Warp and weft yarns go over and under (interlace) each other at 1:1 
ration 5. Face and back of fabric are the same Balanced Roughly equal yarns/inch in both warp and weft direction Properties Good abrasion and snag resistance Lower resiliency Typically poor drape  o How much can depend on fiber, yarn, weight Poor luster Uses Wide variety of uses, based on type of yarn or fiber used, thread count, or 
fabric weight
o Casual or “cotton like” fabrics
background image EXAM 2 Study Guide Fall  2018 Gingham, chambray, flannelette, challis, lawn, linen look o Formal of “silk like” fabrics China silk, organza, chiffon, georgette, some lining fabrics Basket Weave 2:2 or 3:3 (etc) yarn ratio Fewer interlacings per inch Can improve resiliency and drape Fabric examples (full or half basket) o Oxford cloth
o Canvas or duck cloth (higher thread counts)
Unbalanced (Ribbed) Yarns/inch is higher in one direction (either warp or weft) o Created ribbed surfaces in one direction Properties Poor drape, more structure Less resilient, lower abrasion resistance Better strength Uses Horizontal rib o Formal Bengaline, taffeta, faille o Shirting Broadcloth, poplin Lengthwise rib o Pincord (two-color summer suiting)
o Ripstop (occasional rib)
Twill Weave Yarn floats over 2 or 3 yarns Floats are staggered from row to row 2:1 or 3:1 ratio (can be 2:2) Creates diagonal ridges on fabric  o Most durable weave type 
o Swatches 69-81
Characteristics Face is side with pronounced diagonal ridges o Creates more visual interest Diagonal can move up towards right or left Fewer interlacings allow yarns to move freely o Better flexibility and resiliency
o Allows for higher thread counts
Uses Often used for sturdy bottom weight apparel or suitings Common fabric names
