3 Woven Fabrics  Interlacing 2 sets of yarns at right angles to each other

4 Plain Weave  Simplest of all weaves  Most common  Over, under; over, under  **broadcloth, gingham, poplin  muslin, and many others

5 Twill Weave  Diagonal weave  **denim, gabardine  **firm, heavy weave

10 Weft Knit**  Uses one yarn  **Single knit, ribbed and jersey

11 Double Knit  2 yarns and 2 sets of needles  Heavier and sturdier  Doesn’t run or ravel

12 Ribbed Knit  Vertical ribs on front and back  Neck and wrist bands on sweaters

13 Jersey Knit  Most common knit  Plain, single knit  T-shirts

14 Tricot Knit  Very fine vertical wales on the right side  Stable knit – lies flat  Doesn’t run or ravel  Lingerie, underwear  Very fast to weave

15 Raschel Knit  Uses extra yarn to create a pattern

16 Non-woven  Leather, lace, felt, disposable fabrics  Heat, moisture  Adhesive, bonding  Yarns and layers

17 Non-woven  Interlocking fibers  Don’t fray or ravel  Flexible  Might tear easily

18 Felting  Hot washing and drying wool  Shrinks  Soft and fluffy

19 Interfacing  Very light to very heavy and stiff  Padding (quilting)  Fusible or sew-in

20 Fabric Finishes  Special treatments applied to improve a fabric’s appearance, texture or performance

21 “Gray Goods”  Before any color or finish is added to the product.

22 Bleaching  Used to remove impurities in fabric to ensure a “true dye.”

23 Yarn Dyed  Yarns are dyed before weaving or knitting.  Good for plaids, checks, and stripes. **

25 Piece Dyed**  Fabric dyed after weaving or knitting

26 Garment Dyed  Fabric is cut and sewn  Entire garment or item is dyed

27 Printing Techniques  Color is transferred to surface of fabric to form a pattern

28 Roller  Printing pres with circular rollers  One for each color

29 Rotary Screen  Fast, inexpensive  3500 yards per hour  Good for large designs**

30 Texture and Performance Finishes  Improves surface feel of fabric  Improve comfort and wear ability

31 Napping  Raised, Fuzzy Fabric

32 Sizing  Extra body and weight  Adds Starch

33 Weighting  A textured finish applied to make the garment stiffer and heavier looking than it is  Advantage is to use a cheaper lighter weight fabric and make it appear stronger than it really is
