    About the Course

    This one-day course will give you a basic understanding of:

    • ASTM textile standards for spun and continuous filament yarn and sewing threads
    • Testing applications for internal quality control
    • Acceptance and certification testing
    The methods covered in this course are extensively used by all greige plants making yarn.


    The course will be tailored to meet the needs of your individual organization. You will learn:

    • When, why, and how these standards are used by the textile and apparel industry
    • About good laboratory practices in the textile industry
    • How to develop expertise and practical knowledge in laboratory techniques using selected and accepted fabric and component test methods
    • How to calculate the test results and show reporting techniques
    • Precision and bias procedures and applications

    Topics covered include:

    • Conditioning Textiles for Testing
    • Mechanical Test Methods
    • Development of Product Specifications and Writing Specifications for Textiles
    • ASTM Tolerances for Yarns (Multifilament Yarn; Yarn Spun on Cotton or Worsted Systems)

    Who Should Attend

    Anyone involved in the manufacturing, purchasing, testing, and evaluation of textile yarns and sewing threads. This includes laboratory managers and technicians from industry or government textile testing laboratories, as well as those involved with the purchase and use of sewing threads.

    Note: An understanding of the application of the test reports and specifications would be useful for purchasing and development personnel, as well as those involved with product certification requirements of ISO/IEC 9002 or QS 9000.

    Fee Includes

    • Referenced ASTM standards
    • Course notes
    • Certificate of Attendence with .7 Continuing Education Units (CEUs)

    About the Instructor

    Robert M. Holcombe, Retired Laboratory Director at Safety Components Fabric Technologies, Inc., has extensive experience in manufacturing production and quality control. His current responsibilities include supervision in various spun and filament programs.

    Holcombe also has over 37 years of experience in physical and chemical textile testing and development of product and SPC support programs; proficiency test programs; and evaluation testing and certifying of various types of yarns and fabrics produced or purchased, including: woolen and worsted, cotton and blend, carpet, automotive products, non-woven, industrial fabrics, aerospace and geotextiles.

    He served on the corporate quality audit team; directs an internal audit program and develops and writes specifications using ASTM, DIN, and ISO test methods. Holcombe received his degree in textile management from Clemson University.

    ASTM and D13 on Textiles

    ASTM is a world leader in the development of voluntary consensus standards. The 82-volume Annual Book of ASTM Standards contain over 13,000 standards written by 140 ASTM technical committees. The standards referenced in this course were developed by Committee D13 on Textiles.
