Standard Terminology Relating to Fasteners and Closures Used with Textiles

SCOPE
1.1 This terminology document covers terminology pertaining to items that are considered fasteners and closures such as buttons, hook and loop touch fasteners, snap fasteners and slide fasteners used in the manufacture of textile products, except for seams and stitches.  
1.2 Section 3, Terminology, is categorized into four subsections, specific to the four areas of specialization under this document:  
1.2.1 Relating to Buttons  
1.2.2 Relating Hook and Loop Touch Fasteners  
1.2.3 Relating to Snap Fasteners  
1.2.4 Relating to Slide Fasteners  
1.3 Terminology relating specifically to buttons covers special terms or special meanings used in the button industry. These apply only to sew-through flange and shank buttons.  
1.3.1 The principal types of buttons defined in this terminology document are illustrated in Figs. 1-8.  
1.5.1 These figures are descriptive only and are not intended to be restrictive as to design.  
1.6 Terminology relating specifically to the textile joining structures (seams and stitches) are discussed in detail in Terminology D5646.  
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
