QualityQuality control- inspecting goods after production to separate acceptable from unacceptable products.Testing after the product is made.From a holistic perspective quality is not the same for all things but is inherent in all objects and actionsProduct quality: is represented by a total of a set of precise and measurable characteristics or components of a finished product.Quality is achieved when products consistently fall within a range of acceptable measures for all dimensions of quality.Products that meet this level of quality are assumed to produce the greatest income and profit for the company.Quality reflects an ever-changing marketplace and satisfies the ever-changing needs of the customer in the market.Why we test for quality:Companies and their employees need to understand how quality affects organizations, standard practices within organizations, consumer behavior, and market competition.One way to be sure quality is the best is through textile testing.Textile TestingLaboratory Testing (accelerated testing)Evaluating characteristics or performance of materials using standard procedures in a specialized facility.Quickly assess material and product characteristics and performance.Advantages-Quick resultsEnvironment is controlledUses specialized equipmentUses trained specialistsDisadvantages-May not be true to actual conditions of use.Wear TestingWear testing is conducted over a long period of time and simulates actual use.Product put to use or worn by consumers.AdvantagesMore realisticSimulates actual useProvides info not available by any other processHelps refine product characteristics, dimensions, and featuresHelps product development specialists understand target market use and expectationsCorrect problems with productsContinually improve products with input from target marketDisadvantagesLong term commitmentExpensiveConditions not controlledSome participants disappear or drop outSome products destroyed by participantsSome participants do not fulfill requirements for product use and careStandardized Testing Conditions70 + 2o F (21+1oC)65 + 2% RH (relative humidity)Criteria standardized testing:Simplicity – easy to read and understandReproducibility - reproducible with respect to user, time, and locationValidity – duplicates or simulates actual end-use situationWhy we use standard test methods:To insure reliabilityFor reproducibilityability to repeat process with same or very similar resultsFor accuracyagreement between true value of property being tested and average of many observations made according to test method by many observersMoisture Regain- amount of water in material determined under prescribed conditionsMoisture Equilibrium- condition reached by specimen when it no longer takes up moisture from or gives up moisture to surrounding atmosphere.Reasons For TestingManufacturers ensure that materials, processes, and products meet requirements.Retailers ensure that products they buy meet expectations for performance, size, fit, and consistencyCompanies assess material characteristics and performance and product qualityTesting OrganizationsWho Does the Testing?Suppliers- the company that supplies the product to the retailer.In-house- the company that produces the product.Independent or contract- a separate business organization that specifically tests materials and products for other companies.OrganizationsAmerican Association of Textile Chemist and Colorists (AATCC)Tests chemical properties of textiles.American Society for Testing and Materials (ASTM)Test physical/mechanical propertiesInternational Organization for Standardization (ISO)Based in Geneva, SwitzerlandServes member organizations throughout the world.Has a member from each country-the member from the U.S. is ANSIThe ISO coordinates efforts among different countries to develop standard test methods that can be applied internationally.American Society for Quality (ASQ)Organization of professionals who work to improve the quality of manufactured goods, services and related factors.Developed code of ethics, publishes a newsletter on Q that includes articles related to quality.American Apparel and Footwear Association (AAFA)National organization that deals with issues of interest to the sewn products industry.As the national trade association representing apparel, footwear, sewn products companies, and their suppliers, AAFA promotes and seeks to enhance members companies competitiveness, productivity and profitability in the global marketplace.American National Standards Institute (ANSI)Represents the U.S. member body in the ISOThe purpose of ANSI is to coordinate voluntary standards development and use in the U.S. and to serve as liaison between U.S. standards organizations and other countries.Standards: A set of characteristics or procedures that provide a basis for resource and production decisions.Something that is established by authority, custom, or general consent.Standard Test Methods: widely accepted test method performed under controlled conditions.Performance Specifications: the statement of how a textile must perform in a particular end use.Parts of a performance specificationTest method name and numberCharacteristics (what you are testing for)Requirements (expected test results)Each end use has a different performance specification sheet.Quality Assurance: the process of designing, producing, evaluating, and assessing products to see that they meet the desired quality level for a company’s target market.Quality incorporated into product in all stages from merchandising and product development through marketing and retailing.Quality assurance is NOT quality control!Quality control: inspecting goods after production to separate acceptable from unacceptable products.Labeling of Textile ProductsThe Importance of LabelingLabeling is an important part of the information needed because the testing procedures ensure the information provided on labels and hangtags is accurate.The manufacturer and retailer are responsible for ensuring that all information required by federal laws and regulations is accurate on the label.Labeling RequirementsPoint of ScaleFiber content- usually sewn in or printed on.Permanently attachedCare informationTextile Labeling: laws which regulate labeling of textiles productsInclude apparel, carpets, rugs, upholstery, window covering, etc.Textile Fiber Product Identification Act (TFPIA)Generic (generic or common name of fiber) fiber content in order by weight-65%
