Endorsement notice The text of ISO 105-C12:2004 has been approved by CEN as EN ISO 105-C12:2006 without any modifications. Introduction The test method in this part of ISO 105 is intended to reflect the ef

18、fect of comprehensive laundering during industrial laundry procedures, as distinct from the domestic washing test methods as given in ISO 105-C05, ISO 105-C06 and ISO 105-C08. Four test conditions are described, one at (92 2)C intended for the evaluation of workwear and three, as given below, at (75

19、 2) C, for the evaluation of bed and table linen and corporate wear: without the addition of peroxy bleach compounds; with the addition of hydrogen peroxide (for the bleaching of white work with coloured trimmings); with the addition of sodium perborate tetrahydrate and tetra-acetylethylene diamine

20、(TAED) (for the bleaching of white work with coloured trimmings). NOTE The addition of TAED/perborate is a conveniently stable way of producing peracetic acid in situ. This method of test does not reflect the effect of optical brightening agents. This method and the single cycle test methods describ

21、ed in ISO 105-C06 and ISO 105-C08 may not reproduce the effect of coloured fabrics treated with certain dye fixing agents and finishes after multiple (5 to 10) industrial washes. EN ISO 105-C12:2006 (E)3 1 Scope This part of ISO 105 specifies methods for determining the resistance of the colour of t

22、extiles of all kinds exposed to all forms of industrial laundering procedures. One cycle approximates to the colour loss and cross staining resulting from chemical and/or mechanical action achieved after multiple (5 to 10) industrial launderings. 2 Normative references The following referenced docum

27、le A specimen of the textile in contact with specified adjacent fabrics is laundered, rinsed and dried. Specimens are laundered under appropriate conditions of temperature, alkalinity, bleaching and mechanical action such that the result is obtained in a conveniently short time. The mechanical actio

28、n is accomplished by the use of an appropriate number of steel balls. The change in colour of the specimens and the staining of the adjacent fabrics are assessed using the grey scale.

The temperature of the water bath is thermostatically controlled to maintain the test solution at the prescribed temperature ( 2)C. NOTE Other mechanical devices may be used for this test, provided

32、 that the results are identical with those obtained by the apparatus described. 5.2 Mechanical stirrer, minimum (1 100 100) min1or equivalent, to ensure dispersion and prevent settling. 5.3 Steel balls, non-corrodible (stainless), approximately 6,0 mm in diameter. 5.4 Adjacent fabrics. 5.4.1 A multi

36、80 mm 160 mm, one specimen in the warp direction and one specimen in the weft direction. In the case of knitwear prepare two specimens. Weigh the two specimens to two decimal places (grams). Fold each specimen across the narrow dimension in the centre of the specimen with fabric face on the outside

37、(see Figure 1). Using dimensionally stable thread, sew along the two sides to form a bag. Place 25 stainless steel balls inside each bag and seal by sewing. 6.2 Adjacent fabrics Either: a) cut a sample of multifibre TV adjacent fabric (5.4.1) and weigh to two decimal places (grams); or b) cut a samp
