6、 Publication(s) referred to 11BS 3F 129:2003 ii BSI 11 September 2003 Foreword This British Standard, prepared under the direction of Technical Committee ACE/21, Narrow woven fabrics for aerospace use, is one of a series for textiles of a quality suitable for aerospace purposes and constitutes a new
7、 edition of BS 2F 129:1991, which is withdrawn. It specifies the requirements for a series of polyester narrow fabrics for use primarily in parachutes, life saving equipment and aircrew protective clothing. It differs from the previous edition in that minimum breaking strengths for some fabrics have
8、 been increased (see Table 3). This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comp

10、polyethylene terephthalate) narrow fabrics for aerospace purposes. NOTE 1 The titles of the publications referred to in this standard are listed on the inside back cover. NOTE 2 The latest revision of an Aerospace Series standard is indicated by a prefix number. NOTE 3 The information to be supplied
11、 by the purchaser in the contract or order is listed in Annex A. 2 General requirements In addition to the requirements specified in Clauses 3, 4, 5, 6 and 7 of this standard, the requirements and tests of the latest edition of BS F 100 specified in Table 1 shall apply. 3 Yarn 3.1 Type The fabric sh
12、all be manufactured from bright, continuous filament, polyester (polyethylene terephthalate) yarn. 3.2 Construction 3.2.1 The yarn shall have the nominal construction given in Table 2. 3.2.2 The tolerances on twist shall be 20 %. 3.2.3 The direction of twist in all fabric designations shall be eithe
13、r all S or all Z. There shall not be different twist directions in the fabric. 4 Manufacture 4.1 The fabric shall be woven either: a) on a shuttle loom; or b) on a shuttleless loom where this is in accordance with the appropriate yarn designation as given in Table 2 (see also 4.2). NOTE The type of
14、weaving required should be specified in the purchasers contract or order (see Annex A), but for supply against this British Standard the two types of weaving are considered to be technically equivalent and either may be supplied. 4.2 Shuttleless construction shall not be used unless the appropriate
15、yarn designation as given in Table 2 is required and, if such a yarn is required, the shuttleless construction shall be one of the following: a) with spool type interlocking in the body of the fabric (see Figure 1 for guidance); or b) with the weft knitted with one locking thread (see Figure 2 for g
16、uidance); or c) with the weft secured by two knitted locking threads (see Figure 3 for guidance). 4.3 The knitted edge of shuttleless constructions complying with 4.2 b) and c) shall be uniform and even. The edge shall be pulled closely into the body of the fabric to avoid beading. 4.4 Fabric design
17、ation 267 shall have a black identifying yarn positioned centrally down the fabric and this shall be included in the total warp ends.BS 3F 129:2003 2 BSI 11 September 2003 Table 1 General requirements (given in BS F 100) 5 Finish 5.1 Condition of material NOTE The condition required should be stated
18、 in the purchasers contract or order (see Annex A). 5.1.1 Fabric designations 296, 5045, 5042, 653, 7849, 201, 206, 267, 5043 and 655 shall be supplied either: a) scoured; or b) scoured and dyed. 5.1.2 Fabric designations 7769, 318, 8552, 5044 shall be supplied either: a) scoured and heat set; or b)
19、 scoured, dyed and heat set. 5.1.3 Fabric designation 5014 shall be supplied scoured, dyed, prestressed and heat set. After prestressing and heat setting, the extension of the fabric shall not exceed 6 % at an applied force of 4 450 N. 5.1.4 Loomstate fabrics shall not be supplied. 5.2 Dyeing Where
20、dyeing is required, the colour of either the fabric or the yarns from which it is to be constructed shall be specified either by reference to a British Standard (e.g. BS 381C) or otherwise by pattern. NOTE The colour required should be stated in the purchasers contract or order (see Annex A). Sectio

25、by the number of this British Standard, i.e. BS 3F 129 1) , together with the appropriate designation and, if required dyed, the colour. NOTE This identification may be codified. For example, webbing designation 5044, required dyed NATO green, may be identified as BS 3F 129/5044/BS 381C/285. 1) Mark
26、ing BS 3F 129 on or in relation to a product represents a manufacturers declaration of conformity, i.e. a claim by or on behalf of the manufacturer that the product meets the requirements of the standard. The accuracy of the claim is therefore solely the responsibility of the person making the claim
27、. Such a declaration is not to be confused with third party certification of conformity, which may also be desirable.BS 3F 129:2003 4 BSI 11 September 2003 Table 2 Yarn construction Fabric designation Warp Selvedge warp Binder warp Weft (conventional) Weft (shuttleless) Spool locking thread for shut
