Textiles Study Guide for Exam 1 – 2/4 Processes The textile industry is international and global can be shown by: Fashion Marketing Technology Fashion Continuously changing/evolving U.S. technology is competitive, but manufacturing is not Has low need for production personnel, but strong need for textileknowledgeable personnel Unique fibers, yarns, fabrications and treatments for materials Textile use percentages by industry: Apparel 35% Interior Furnishings 35% Industrial 30% 5 Major Production Segments: o Fibers – hairlike substances – smaller of the fabric o Yarns – continuous threadlike strands of fibers twisted together o Fabric – actual cloth made by combining yarns (knitting and weaving) o Dying and printing – coloring and putting pattern on fabric o Finishing – typically an end process for fabric Why there is an import industry in the U.S.: low cost of labor superior products Fabric is bought according to written specifications of a brand sponsor and is obtained from a sample Fabric is sold require laboratory testing and customer approval then sold at first in small quantities to the interested buyer, and if well received, is purchased by the buyer Shipping (‘put up’) Fabric how fabric is supplied: Short < 40yds of fabric Remnant 110yds of fabric Pound Goods <1yd of fabric Terms and Definitions Absorbency (hydrophobic vs. hydrophilic) skin comfort static build up wrinkle recovery Abrasion resistance the ability of a fabric to resist surface wear caused by rubbing contact with another material Chemical effects different fibers react differently to dyeing and finishing Converters – individual or an organization that buys unfinished goods, have fabric dyed, printed, and finished by other companies; a primary source of fabric Cover – ability to occupy an area (wool fibers with crimp give excellent cover) Domestic Textile Industry – companies produce or buy textiles in their own country for sale within or export outside their country Complex, diverse and labor intensive Late 1980s – a shift from a mostly domestic industry to primarily import industry in the U.S. (lower cost) Only those who modernize or make production more efficient make specialty fabrics and develop export sale programs survive Dry Spinning – fiber solution forced through spinneret into warm air; the air helps evaporate the solvent and the liquid stream then hardens (acetate, modacrilic) Eight Fiber Shapes: serrated, square with void, dog bone, round, flat/oval with convolutions, trilobal, hollowcore fiber microscopic views can determine fiber shape, surface, longitudinal configuration, crosssection configuration and diameter fiber shape influences light reflection: Triangle shape – good luster Round shape –fair luster Irregular shape – poor luster Elasticity – elongation and recovery (spandex) Filament fibers – fibers of longer length (mostly synthetic fibers) Flammability – able to ignite or burn Griege unfinished fabrics Hand – how a fiber feels when handled Hyrdrophilic –absorbs water easily Hydrophobic – does not absorb water Import Textile Industry – companies produce or buy textiles/finished products from all over the world for import or sale in their own countries Direct importer – buys fabric or manufactured textile products from a foreign or other supplier and brings it to U.S. Import Mill – a foreign company that owns textile machinery and makes fabric that is exported to a U.S. mill in selling its fabric Importers – companies produce or buy textiles, and/or finished products from all over the world for import and sale in their own countries; a primary source of fabric Jobbers part of secondary source of fabrics buy from mills, converters and garment manufactures discontinued styles, colors and mills overruns low prices, interesting fabrics, but no continuity of a fabric small/specialized enduser companies Luster – amount of light reflected Manufactured Fibers petroleum products – spinning process used for to create these Melt Spinning – solid material is melted into liquid that is forced through a spinneret and into cool air where the liquid fiber streams harden into continuous filaments (glass, nylon, polyester, olefin) Mills – a company that owns textile machinery and makes fabrics; a primary source of fabric Natural Fibers Plant Fibers stem (flax, hemp, jute, ramie) leaves (sisal, abaca) seed (cotton, kapok) Wool – a natural protein fiber cashmere, mohair, silk Overseas Agents part of secondary source of fabrics represents an exporter/importer in the countries overseas local business, local customs and regulations Pilling – formation of small balls of entangled fiber ends usually occurring because of abrasive or rubbing action on the fabric surface (can mean that it is a low quality fabric) Primary Source of Fabric Mills, converters and importers most sales based on contracts usually produce larger orders Retail Stores part of secondary source of fabrics sell to home sewers overthecounter sales Secondary Source of Fabric Jobbers, retail stores and overseas agents buy cloth, then sell it – not involved in making the material textile brokers may be the middle man in the transactions mentioned above Staple fibers – fibers whose lengths are measured in inches (mostly natural fibers) Thermoplastic – able to be melted (permanent press) Wet Spinning – fiber solution is forced through the spinneret and then into a liquid solution; streams then harden into continuous filaments (acrylic, viscose rayon)
