1、BRITISH STANDARD BS 4973-2: 1973 Specification for Interlinings Part 2: Nonwoven fusible interlinings UDC 687.182:687.152.076BS4973-2:1973 This British Standard, having been approved by the Linen Industry Standards Committee, was published under the authorityof the Executive Boardon 19 October1973 B

2、SI 12-1999 The following BSI references relate to the work on this standard: Committee reference LIT/7/1 Draft for comment 72/70564 DC ISBN 0 580 07598 2 Co-operating organizations The Linen Industry Standards Committee, under whose supervision this British Standard was prepared, consists of represe

3、ntatives from the following Government departments and scientific and industrial organizations: Belfast Public Textile Testing Part 2: Nonwoven fusible interlinings; Part 3: Woven fusible interlinings (in course of preparation). It is intended that the fabrics in this specification should be used in

4、 conjunction with the outer cloths specified in BS1771, “Outdoor uniform cloths for fire service, local authority and hospital staffs”. Attention is drawn to the fact that, with certain types of fabric and finish, perfect fusing may be difficult. A British Standard does not purport to include all th

5、e 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. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii,

6、 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 will be indicated in the amendment table on the inside front cover.BS4973-2:1973 BSI 12-1999 1 1 Scope This Part of this British Standard specifies r

7、equirements for nonwoven fusible interlinings for uniform clothing for large users such as Government departments, fire services, hospitals and local authorities. Technical requirements are tabulated in Table 1 and recommended uses in Table 2. NOTEThe titles of the British Standards referred to in t

8、his standard are listed on page no. 4. 2 Definitions For the purposes of this Part of this BritishStandard, the following definitions apply: strike-through penetration of the adhesive from the interlining to the face of the outer fabric strike-back penetration of the adhesive to the outer surface of

9、 the interlining 3 Fusing Fusing instructions shall be supplied with the interlining, and these shall be followed exactly bythe maker-up. In this case, there shall be no strike-through and strike-back shall not be sufficient to cause subsequent adhesion to the lining and/or pocketing. At least24 hou

10、rs shall be allowed to elapse between fusing operations and the carrying out of tests. 4 Technical requirements 4.1 The mass per unit area of the fusible interlining most suitable for use with the outer fabric shall be agreed between the purchaser and the manufacturer, and shall be within one of the

11、 ranges given in Table 1. The mass per unit area so agreed shall be subject to a tolerance of 10%. 4.2 The bursting strength shall be as shown in Table 1 when tested by the method specified in BS3137 for the determination of bursting strength of paper. 4.3 The flex resistance and durability of the l

12、aminate (i.e.outer fabric plus interlining) shall be assessed after each specimen has been subjected three times to the treatment given in BS4961 which gives two methods of test for dry cleaning (including steam finishing). The laboratory procedure is intended primarily for screening and control tes

13、ting and in cases of dispute the machine procedure shall be used. 4.4 Peel bond strengths vary according to the construction of the outer fabric and the type of finish the cloth has received. It is not practicable to specify a minimum strength that will be adequate for all the fabrics listed in BS17

14、71. It is therefore recommended for quality control purposes that the peel bond strength shall be as agreed between the purchaser and the supplier, according to the specific fabric and fusing method involved. A method for determination of peel bond strength is given in Appendix A. 4.5 Dimensional ch

15、ange on cold water immersion shall be limited as shown in Table 1. 4.6 For purposes of general comparison in respect of handle not specified in this British Standard, agreement shall be reached between the purchaser and the manufacturer. There shall be no appreciable change in handle of the laminate

16、 after dry cleaning. 5 Marking Each cloth in the finished state shall be identified by this British Standard reference number, (i.e.BS4973), either by stamping or by labelling. NOTEAttention is drawn to the certification facilities offered by BSI. See the inside back cover of this British Standard.

21、rmination of peel bond strength A.1 General This test is performed on specially prepared specimens of laminate (i.e.interlining fused to outer fabric). Whilst compliance with the requirements of this British Standard depends on the satisfactory appearance of the laminate after three dry cleaning tre

22、atments, this method for determination of peel bond strength is suggested for use for quality control purposes. A.2 Apparatus The apparatus consists of two grips capable of accommodating a test specimen50mm in width. One grip is attached to a rigid support so that when a specimen is inserted central

23、ly and normally it hangs in a vertical plane. The other grip is so constructed that it has a mass of200g and weight-pieces of200g mass may be added to it. A.3 Preparation of test specimen Prepare four composite specimens in the following manner. Cut a specimen100mm 50mm of outer fabric and interlini

24、ng. Mark a line on the interlining25mm from one end and at right angles to the longer edges. Insert a25mm 50mm piece of thin metal foil between the interlining and outer fabric to prevent fusing over this area, and fuse the interlining to the outer fabric, in accordance with the manufacturers instru

25、ctions. Allow at least24 hours to elapse before proceeding. A.4 Procedure Secure the tongue formed by the outer fabric in the fixed jaw and the tongue formed by the interlining in the loose jaw, which has been made up to thespecified mass by the addition of200g weight-pieces. After five minutes, rec

26、ord the distance from the line marked on the interlining tothe apex of the separation. A.5 Report Report the separation distance, if any, in millimetres and the load applied. If the interlining ruptures before peeling, this should be reported as “interlining breakdown”.BS4973-2:1973 4 BSI 12-1999 Pu
