8、90 ii BSI 08-1999 Foreword This Part of BS1771 has been prepared under the direction of the Textiles and Clothing Standards Policy Committee and specifies requirements for fabrics made from cellulosic fibres, synthetic fibres and blends of synthetic fibres with cellulosic fibres. BS1771-1 contains r
9、equirements for fabrics made entirely from wool or from blends of wool and other fibres. It was decided to produce a revision of the1984 edition of BS1771-2 to provide a range of fabrics characterized by performance rather than by detailed construction in addition to performance. This Part of BS1771
10、 supersedes BS1771-2:1984 which is withdrawn. As with the previous edition of this Part of BS1771, the fabric references allocated to the fabrics listed in Table 1 and Table 2 have been chosen with the aim of assisting the non-technical purchaser in making a choice of fabric type for his known end-u
11、sage. BS1771-2 covers only the basic description of the products and their performance requirements. Purchasing authorities therefore may need to include additional information. Many properties cannot be specified objectively and cannot therefore be included in the standard. Examples of such propert
12、ies include colour, handle appearance and details of additional design features. Purchasing authorities may be able to supply standard patterns which cover these properties and which may serve to resolve any ambiguities of description. A British Standard does not purport to include all the necessary
13、 provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. In particular attention is drawn to Statutory Instrument No. 26 1986 Trade Descriptions, the Textile Prod
14、ucts (Indications of Fibre Content) Regulations 1986. Summary of pages This document comprises a front cover, an inside front cover, pagesi andii, pages1 to4, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This wil
15、l be indicated in the amendment table on the inside front cover.BS1771-2:1990 BSI 08-1999 1 1 Scope This Part of BS1771 specifies minimum performance requirements for a range of woven knitted fabrics made from cellulosic fibres, synthetic fibres and blends of synthetic fibres with cellulosic fibres,
16、 suitable for the manufacture of uniforms and workwear garments. Reference numbers have been allocated to the fabrics listed, with the aim of assisting the non-technical purchaser in making a choice of fabric type for known end-usage. NOTEThe titles of publications referred to in this standard are l
17、isted on the inside back cover. 2 Definitions For the purposes of this Part of BS1771, the definitions given in BS6189 apply, together with the following. 2.1 batch a definite quantity of some commodity manufactured or produced under conditions which are presumed uniform 2.2 bulk the total length of
18、 fabric included in the contract of supply 2.3 lot the total number of rolls of fabric included in any part delivery of the bulk 3 Fabric references Fabrics shall be designated by a condensed technical description containing the following: a) a letter to indicate whether woven (W) or knitted (K); b)
19、 a letter or letters to indicate as follows the fibre type, when determined in accordance with BS4407: C for100% cellulosic; CR for an intimate cellulosic fibre and synthetic fibre blend fabric, containing not less than50% cellulosic fibre; SR for an intimate cellulosic fibre and synthetic fibre ble
20、nd fabric, containing less than50% cellulosic fibre; PE for100% polyester; PA for100% polyamide. c) a space; d) a figure to indicate the minimum mass per unit area in grams per square metre; e) a space; f) a letter to indicate the colour fastness grade L, M or D; g) a letter to indicate the dye type
21、 as follows: A for azoic dye; H for hydron dye; K for mineral khaki dye; S for sulphur dye; V for vat dye. NOTEFor example WC280LV indicates a woven cellulosic fibre fabric with a minimum mass per unit area of280g/m 2 , with colour fastness grade L and vat dyed. 4 Fabric performance Woven fabrics sh
22、all comply with Table 1. Knitted fabrics shall be raschel warp-knitted and shall comply with Table 2. NOTE 1Yarns should be evenly spun. Selvedges should be firm and straight and of a thickness such as not to lead to unacceptable “build-up” during laying-up for garment cutting. NOTE 2The figures quo
23、ted for dimensional change on washing relate to one wash followed by press drying. Successive additional washes, as in actual use, will result in progressive shrinkage and other methods of drying, e.g.tumble drying, may result in a greater shrinkage than that specified. NOTE 3Certain types of flame-
24、retardant finish may reduce the strength of fabrics, particularly cellulosic fabrics. Where flame-retardant finishes are used interested parties may agree to specify alternative strength requirements, but such a fabric could not be claimed to comply with this Part of BS1771. 5 Colour fastness Fabric
25、s shall comply with Table 3 or Table 4 as appropriate. NOTE 1The colour fastness to washing test BS1006-CO6: test method E2S is a laboratory test to indicate the change of colour on washing. It does not take into consideration the fluorescent brightening agents (FBAs) which are present in some comme
26、rcial washing products and which can therefore increase the change of colour. NOTE 2Where combinations of fabrics and/or colours are to be used in a garment, reference should be made to the supplier of the fabric for suitability with regard to cross staining. NOTE 3Where chlorine containing bleaches
27、 are used in laundry processes, reference should be made to the supplier with regard to suitability. NOTE 4Certain special colours may not conform to the specified requirements, and reference should be made to the supplier. 6 Sampling, testing and compliance 6.1 Sampling Sampling shall be carried ou
28、t at the discretion of the testing authority in such a manner that samples taken are representative of the manufacturing, processing, dyeing or finishing batch from which they are drawn.BS1771-2:1990 2 BSI 08-1999 Table 1 Woven fabrics (performance) Table 2 Knitted fabrics (performance) Samples of t
29、he fabric taken for testing for compliance with the requirements of this standard shall be representative of each batch. One sample shall be taken from each5 000m of fabric or if the batch is less than5 000m, one sample shall be taken from each batch. Each sample shall be taken from a different piec
30、e and shall be taken from the middle of a dye lot. It shall be large enough to provide material for all the tests required by this standard and shall be identified with the piece or roll from which it was taken. 6.2 Selection of test specimens Test specimens shall be selected from the sample taken i
31、n compliance with6.1 in such a manner that the full width and length of the sample is represented in each set of test specimens. 6.3 Testing All the physical tests required shall be carried out on each sample. Chemical tests and colour fastness tests shall be carried out on one sample from each batc

38、han50 C before being exposed to the standard temperate atmosphere for the conditioning and testing of textiles, defined in BS1051, for at least24h before testing. 6.5 Re-tests Should a sample fail any test, two further samples shall be selected from two different pieces in the same batch. Each of th
39、ese samples shall be tested, and if either fails the whole batch shall be rejected. If both the re-test samples pass, the batch shall be accepted, but the piece from which the failed sample was taken shall not be included in the delivery. 7 Marking Each piece or roll of fabric shall bear the followi
40、ng information, e.g.on a label or swing ticket: a) name, trademark or other means of identification of the manufacturer; b) fabric reference in compliance with clause3; c) contract number, where applicable; d) piece number; e) length of the piece or roll, in metres; f) width of the fabric, in centim
