  3. 1. Weft Knit • Weft, or filling knits are made with only one yarn. • Done by hand or machine • Most have two-way stretch, lengthwise and crosswise • Can get lengthwise “runs” from broken threads because of single yarn construction Method of Knitting

  4. Plain – most common, sometimes called jersey, front and back are different; used for hosiery, t-shirts, sports shirts, dresses, and sweaters • Purl – same on both sides, stretch lengthwise and crosswise; used for sweaters Types of Weft Knits

  5. Rib – have vertical ribs or columns of stitches that alternate on the front and back; used as neck, wrist, and bottom bands on sweaters and jackets • Double – made with two yarns and two sets of needles, heavier, firmer, and sturdier than other knits, will not run or ravel; can be used for a variety of garments Types of Weft Knits cont.

  6. 2. Warp Knit • Warp knits are made with several yarns on flat knitting machines. • Yarns interlock • Each loop is made up of two yarns • Usually run-resistant Method of Knitting

  8. Fibers, yarns, and fabric can be joined together by heat and moisture, adhesives, bonding agents, or stitching. Other Fabric Constructions

  9. Made by interlocking the fibers with heat and moisture or with an adhesive substance • Felt is a nonwoven fabric • Do not ravel or fray • Flexible and have good shape retention • May have weak areas and may tear easily • Inexpensive to produce • Diapers, interfacing, and disposable surgical gowns are end uses Nonwoven Fabrics

  10. Woven or knitted fabrics that have been constructed to stretch more than they normally would. • Can be designed to stretch in warp direction, filling direction, or both. • Two-way stretch fabrics are suitable for swimsuits, exercise wear, and active sportswear. Stretch Fabrics

  11. Can be bonded to another fabric, vinyl, clear films, or rubberized coatings • Simulated leather has vinyl bonded to a woven or knitted base. • Rubberized coatings can be added for water repellency. Bonded and Laminated Fabrics

  12. Made by twisting or looping threads or yarns together on special machines Laces and Nets
