E N D
Objectives: • Identify most common fabric constructions • Describe main fabric finishing procedures • Recognize importance of quality and performance standards • Summarize aspects of the textile industry • Explain how fabrics are sold down the chain • Cite textile industry trade information • Tell about future predictions for textiles
Fabric Design and Construction • Two forms of design • Structural Design • “Building in” texture or interest during manufacturing process • Weaving and knitting most common • Applied Design • Adding color, pattern, or other features to the structural design • Printing on fabric
Weaving Plain: crosshatch pattern Twill: diagonal wale Satin: floating yarns Knitting Weft Warp Nonwoven Fused Felted Films Fabric Construction Methods
Fabric Terms • Grain – direction yarns run in the fabric • Lengthwise - warp • Crosswise - weft • Diagonal - bias • Selvage • “Finished” weft edge of fabric SELVAGE WARP WEFT BIAS SELVAGE CUT EDGE
Variations of Weaves • Stripes • Checks • Plaids • Jacquard • Pile fabrics • Terry cloth • Corduroy • Velvet
Knitting • Looping yarn together • Made using one yarn • Built-in stretch • Wrinkle resistant • Does not ravel like woven material, but may run • Weft (filling) stretches in both directions • Warp stretches one direction; run-proof
Nonwoven Fabrics • Compact web of fibers (not yarns) constructed using • Moisture • Heat • Chemicals • Friction • Pressure • No grain
Other Construction Methods • Laces and Nets • Made by knotting • Decorative trim • Braids • Decorative trims • Bonded fabrics • Fusible web • Interfacing and hem tape • Quilted fabrics
Fabric Finishing • Converters • Mills that change greige goods into finished fabrics • Applying colors, designs, or surface treatments • Bleaching • Dyeing • Printing • Finishes
Dyeing • Fiber • Adding color to fibers before spinning into yarns • Yarn • Placing yarns in dye bath before making into fabric • Piece • Fabrics dyed after weaving or knitting • Garment • Dyed after construction
Printing • Adding color, pattern, or design to surface of fabric • Overall prints • Same across fabric • Directional prints • Specific direction to pattern • Plaids • Even - same in warp and weft • Uneven - different in warp or weft
Roller Applies color design by roller Screen Similar to stenciling Rotary Screen Applies color design by cylinder-shaped nylon screens Heat Transfer Design on printed paper transferred to fabric by heat and pressure Digital Computer method uses ink-jet printing Flocking Fibers attached by patterned glue Printing Methods
Fabric Finishes • Mechanical finishes affect size and appearance • By heat, moisture, stretching, singeing • Example: preshrinking • Chemical finishes affect performance • Permanent press • Waterproof • Water repellent • Flame resistant • Antistatic • Stain and soil resistant
Standards • Quality • Rate textiles according to levels of defects • Performance • Rate textiles for specific end-use suitability
The Textile Industry • Specialized companies perform stages of the textile segment of the chain • Technology necessary • CAD/CAM • Fashion • Tracking designs, trends, forecasts • Marketing • Planning, pricing, promoting, distributing
Selling Finished Fabrics • Staple fabrics • Sold each year with little or no change in construction • Novelty fabrics • Fashion fabrics that change with style trends • Overruns • When a mill makes more fabric than was ordered by customers
Trade Information • American Textile Manufacturers Institute, Inc. (ATMI) • Industry-wide marketing, government relations, trade policies • American Printed Fabrics Council, Inc. (APFC) • Printing achievements • American Association of Textile Chemists and Colorists (AATCC) • Wet processing aspects TEXTILES
Future of Textiles • Continued U.S. innovation • Stay internationally competitive • Update plants • Continued automation • Flexibility and versatility for shorter production runs of different fabrics • Increased knit production • Textile firms need more sophisticated marketing techniques
Do You Know . . . • A finishing term that ends in “proof” means complete protection (as in waterproof). • Hand is the term used for textiles that refers to the way fabrics feel to the touch. Hand may apply to drape, softness, firmness, crispness, or elasticity.
