12、rns 1 Scope and field of application This International Standard provides a basis of specification ap- plicable to textured yarns made from textile glass. Textured glass yarn is a textile glass continuous filament yarn (single or folded) in which the filaments have been deliberately and per- manentl
13、y separated to increase the bulk of the yarn (see IS0 6355). Textured glass yarns can be produced by several types of pro- cess. They can be made either starting from a single strand or from two or more strands in which one or all have been “opened“ to give the “bulky“ aspect of textured yarn. Textu
14、red glass yarn is used in various applications, for example insulation, filtration, decorative textiles, reinforcement of plastics, fabrication of packings. 2 References IS0 1886, Textile glass - Method of sampling applicable to batches, IS0 1887, Textile glass - Determination of combustible matter

17、eptance criteria Sampling shall be carried out in accordance with IS0 1886. The supplier shall indicate in his specifications the method of sam- pling (attributes or variables) and the acceptable quality level for the various characteristics of the applicable yarn. 4 Designation The designation shal
18、l conform to IS0 2078. 5 Physical properties Unless othewise agreed, the textured glass yarns shall be defined by the following characteristics for which nominal values and tolerances shall be given in the technical specifi- cations of suppliers. 5.1 Type of glass Various types of glass are used in
19、the production of textured yarns. A list of available glass types is given in IS0 2078. 5.2 Size The texturizing process requires the use of yarn covered with a size allowing an appropriate lubrication during texturization. This size can be eliminated after weaving by a heat-cleaning treatment, if n
20、ecessary. Size content shall be determined ac- cording to IS0 1887. 5.3 Average filament diameter Average filament diameter shall be determined according to SO 1888. 5.4 Linear density Linear density shall be determined according to IS0 1889, but care shall be taken to adjust pretension to the level

22、: 1987 (E) 5.5 Moisture content Moisture content shall be determined according to IS0 3344. 5.6 Breaking load Textured yarn may present a strength at elastic yield much in- ferior to the breaking load. If this is the case, the specifications of the supplier shall indicate the minimum value for the s
23、trength at elastic yield and for the breaking strength, as determined ac- cording to IS0 3341. 6 Visual properties - Defects The technical specifications of suppliers shall indicate the nor- mal visual characteristics and defects that can be present on the yarns and packages (see examples in 6.1 and
24、 6.2). The ac- ceptable level in number or importance shall be agreed between supplier and buyer. If necessary, reference samples shall be kept by the supplier in order to appraise any disputed packages especially for defects (see 6.1) Nos, 6.1.3, 6.2.2, 6.2.3 and 6,2,10, 6.1.7 Badly made knot or sp
