7、side back coverBS5866-1:1990 ii BSI 09-1999 Foreword This Part of BS5866 has been prepared under the direction of the Textiles and Clothing Standards Policy Committee and supersedes BS5866-1:1980 which is withdrawn. BS5866 specifies requirements for a range of blanket types suitable for use in the p
8、ublic sector and is published in four Parts as follows: Part 1: Specification for wool and wool/polyamide blankets; Part 2: Specification for cotton leno cellular blankets; Part 3: Specification for synthetic fibre cellular blankets; Part 4: Flammability 1) . In this Part, requirements are specified
9、 for blankets made entirely from new wool, grey wool blankets and blankets comprising fibre blends of new wool and staple polyamide. BS5866 covers only the basic description of the products and their construction and performance requirements. Purchasing authorities therefore may need to include addi
10、tional information. Many properties cannot be specified objectively and cannot therefore be included in this standard. Examples of such properties include colour, handle, appearance, extent of raising and details of additional design features. Public sector purchasing authorities may be able to supp
11、ly standard patterns which cover these properties and thereby serve to resolve any ambiguities of description. This Part of BS5866 differs from the previous edition in that revised requirements are specified for the all-wool blanket. The previous edition included requirements that were contained in
12、BS1681 (which was withdrawn on publication of BS5866-1:1980) except that the values were metricated and rounded upwards. In the preparation of this edition of Part1 of BS5866 it was considered that the construction and performance requirements for the all-wool blanket should be realigned with that o
13、f BS1681. Requirements for flame-retardant blankets will be included in this Part of BS5866 on publication of Part4. Appendix A gives a method for determining dimensional change on washing and Appendix B gives guidance on information to be supplied by the purchaser. A British Standard does not purpo
14、rt to include all the necessary 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 1986 No. 26, the
15、 Textile Products (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 incorpora
16、ted. This will be indicated in the amendment table on the inside front cover. 1) In preparation.BS5866-1:1990 BSI 09-1999 1 1 Scope This Part of BS5566 specifies requirements for woven wool and woven wool/polyamide blankets intended for use in the public sector. It deals with the composition, manufa
17、cture, make-up, dimensions and colour of the blankets. Values are prescribed for percentage fibre content and mass per unit area, threads per unit length in warp and weft, breaking strength, dimensional change on washing and colour fastness. NOTEThe titles of the publications referred to in this sta
18、ndard are listed on the inside back cover. 2 Definitions For the purposes of this Part of BS5866, the definitions given in BS6189 apply, together with the following. 2.1 lot the total number of blankets included in any part delivery of the bulk 2.2 bulk the total number of blankets included in the c
19、ontract of supply 3 Composition 3.1 New wool blankets New wool blankets shall be composed entirely of new wool. The blankets shall be designated as follows. A: blankets unraised, with shrink-resistant and flame-retardant finishes; B: blankets raised, without a shrink-resistant finish; C: blankets ra
20、ised, with a shrink-resistant finish. 3.2 Grey wool blankets Grey wool blankets shall contain a minimum of95% wool. 3.3 Wool/polyamide blankets Wool/polyamide blankets shall have warp and weft yarns composed of fibre blends containing a minimum of70% new wool, the remainder being6.7dtex,60mm staple-
21、fibre polyamide. Table 1 Properties Property Finish New wool Grey wool Wool/polyamide Test method Mass per unit area, g/m 2(min.) No.of threads per cm (min.)

The mass per unit area, number of warp and weft threads per unit length, breaking strength and dimensional change on washing shall be as given in Table 1. NOTE 1Yarns should be evenly spun,
24、 the weave should be uniform with firm and straight selvedges and raising should be even. NOTE 2No requirements for treatment against moths are specified but interested parties may agree as to whether the blankets should be treated and if so on the type of such treatment. BS4797 includes a method of
25、 test for resistance of textiles against the common clothes moth, and BS2087-1 includes preservative treatments for protection against moths. 5 Make-up 5.1 Stitching With the exception of cot blankets, blankets shall be either turned15mm and stitched at both ends only or turned15mm and stitched all
26、round. Cot blankets shall be turned15mm and stitched all round. NOTEStitching is intended to prevent fraying. 5.2 Dimensions The dimensions of the blanket shall be as given inTable 2 when determined as described in BS5129. NOTEBS5129 gives a range of recommended dimensions for blankets not specifica
27、lly intended for use in the public sector. Table 2 Dimensions 6 Colour 6.1 Range of colours 6.1.1 With the exception of grey wool blankets, blankets shall be either natural wool coloured or dyed. NOTEInterested parties may agree upon the colour. 6.1.2 Grey wool blankets shall be grey or grey/brown o
