21、ur fastness - Part 21 1 : Evaluation of speckiness of colorant dispersions 1 Scope This International Standard describes a test method to determine speckiness primarily of disperse dye, vat dye and pigment dispersions. Agglomerates in colorant dispersions may become apparent as specks on a continuou
22、sly dyed (padded), or on a printed fabric, especially when pale and light shades are produced. 2 Normative reference The following standard contains provisions which, through reference in this text constitutes provisions of this part of IS0 105. At the time of publication, the edition indicated was
23、valid. All standards are subject to revision and parties to agreements based on this part of IS0 105 are encouraged to investigate the possibility of applying the most recent edition of the standard listed below. Members of IEC and IS0 maintain registers of currently valid International Standards. I

25、persed, for polyester, polyamide and some other manufactured polymeric fibres. 3.2 dispersion: In textile dyeing and printing, a suspension of very fine colorant particles in a liquid phase. 3.3 pigment: colorant in particulate form which is insoluble in the substrate but which can be dispersed in t
26、he substrate to modify its colour. 3.4 speck small particle, such as an agglomerate in liquid dispersion, or a very small spot of dark colour on a dyed substrate. 3.5 speckiness: In textile dyeing and printing, the quality or state of containing specks. 3.6 vat dye: water-insoluble dye, usually cont
27、aining keto groups, which is normally applied to the fibre from an alkaline aqueous solution of the reduced enol (leuco) form which is subsequently oxidized in the fibre to the insoluble form. 1 STD.BSI BS EN IS0 LOS-ZLL-ENGL 2OOL Lb24bb 08921L5 hl13 EN IS0 105-Z11:2000 4 Principle A dispersion of a
28、 dye is filtered through a polyester/cotton blend fabric, then dried and thermofixed. The degree of speckiness is assessed visually. 5 Safety precautions Good laboratory practices should be followed. Wear safety glasses in all laboratory areas, All chemicals should be handled with care Use heat resi
29、stant gloves when working at hot air ovens and themofixation devices. Users should also comply with any national and local safety regulations. N0TE:These safety precautions are for information purposes only. The precautions are ancillary to the test procedure and are not intended to be all-inclusive
30、. It is the users responsibility to use safe and proper techniques in handling materials in this test method. Consult manufacturers for specific details such as material safety data sheets and other manufacturers recommendations. 6 Reagents 6.1 Sodium hydroxide, 30 % (dv) E 300 g/l. 6.2 Sodium hydro
31、sulfite, powder (N%S20,). 6.3 Hydrogen peroxide, 30 YO (dv) 2 300 gh. 6.4 Acetic acid, 80 % (dv) 2 800 g/l. 6.5 Grade 3 water, (see 8.1 of IS0 105-A01:1994). 7 Apparatus 7.1 Filter cloth, 65/35 (dm) polyesterkotton, bleached woven broad cloth (shirting weight, approximately 100 g/m), approximately 2
32、40 mm x 240 mm square. A fabric of similar construction and of varying blend ratios may be used, but it shall then be stated in the test report. NOTE The following fabric has been found to be suitable. - Warp and weft/filling yams: approximately 12 tex. - Construction: warp approximately 50 ends/cm
33、wefilling approximately 28 pickdcm - The fabric is desized, bleached, dried and framed to 150 cm to 155 cm and heat set at 200C. These processes are carried out in accordance with generally accepted industrial practice. 7.2 Buchner funnel, polypropylene, 110 mm diameter, with separate top and bottom
34、. Cut out the perforated bottom smoothly and even with the rim, using a knife or other suitable implement. Both parts are used in the test. 7.3 Filtering flask, 2 I, heavy wall with side tabulation. 2 STD.BSI BS EN IS0 105-ZLL-ENGL 2001 1b24bb 089211b 55T EN IS0 106-Z11:2000 7.4 Rubber stopper, 1 ho
35、le, to fit the filtering flask. 7.5 Stirrer, small propeller type, diameter approximately 20 mm, speed up to 2 200 rpm (37 s-). 7.6 Evaporating dishes, 1 I, glass or porcelain, (approximately 150 mm diameter), three, for testing vat dyes. 7.7 Ovens for the following operations: - Drying, without air
36、 circulation; - Themfixation. 8 Preparation of liquid dispersion for sampling Before removing a sample for testing, mix dispersions thoroughly in drums using a mechanical mixing device, such as a propeller stirrer or homogenizer, so that the liquid is smooth and free of sediment and lumps. Shake lab
37、oratory samples thoroughly to ensure that all dried material adhering to the cover and sides of the container is reincorporated into the liquid. Then remove the cover and stir the sample either mechanically, or by hand, until all sediment and/or lumps are completely redispersed. Replace the cover an
38、d once again shake to ensure complete homogeneity. Once the test sample has been removed for use and the balance of the dispersion is to be stored for future use, clean the lid and the containers lip thoroughly prior to closure. Test the sample immediately after homogenization. NOTE On prolonged sto
39、rage, liquid dispersions tend to settle and may develop a more or less tacky sediment. It is imperative to ensure complete homogenew of the dispersion prior to testing. 9 Procedure Identify the filter cloth with the experiment or sample number in one of the corners and ensure that it is free of extr
40、aneous specks. Clean and dry the funnel. Prepare the funnel assembly by placing the top part of the funnel upside down on a clean surface and drape the fabric over it as flat as possible with the identification mark facing down towards the surface. The side of the fabric with the identification will
41、 then be on top during filtration and is used for subsequent evaluation. Snap and press the bottom half of the funnel to the top half, causing the fabric to become a tight, smooth filter in the funnel. Place the assembled funnel straight on the filtering flask using the rubber stopper to ensure that
42、 the funnel remains upright (and the filter fabric horizontal) during filtration and rinsing. Weigh the powder or liquid dye into a weighing cup and transfer to a 400 ml graduated beaker containing grade 3 water at 20 OC to 30 OC. Rinse the weighing cup with water from a spray bottle. Record the qua
43、ntity of dye used. NOTE The amount of dye used is directly proportional to its dyeing strength and is typically (2,5 I 0,025) g for a very high strength solid brand to (20 +: 0,2) g for a low strength liquid. As a reference (75 f 0,075) g of a dye is used if it gives a 1/1 standard depth of shade fr
44、om 2 % (on mass of fibre) of dye applied (in an exhaust dyeing process). The masses of other dyes used in either liquid or solid forms are propottional to this reference. With powder and granular forms, stir for 3 min with a small propeller stirrer with the propeller in the centre and just above the
45、 container bottom, Adjust the speed to create a vortex terminating at the top of the propeller. With liquid forms, stir as for powders, but for 30 s. After the specified stirring time, transfer the dispersion to the 1 I beaker. Rinse the 400 ml beaker with 200 ml of water (6.5) at 20 OC to 30 OC and
46、 pour the rinse water into the 1 I beaker. Dilute the dispersion further to 800 ml. Pre-wet the fabric in the filter with 200 ml water (6.5). 3 STD-BSI BS EN IS0 105-ZLL-ENGL 2001 Lb24bb9 0892117 49b EN IS0 105-Z11:2000 Stir the dispersion in the beaker for approximately 30 s and pour it into the fu
47、nnel. Rinse the beaker with 200 ml water and pour it into the funnel. Rinse the funnel with an additional 200 ml water and let stand for about 1 min until dripping has completely stopped. Carefully remove the filter fabric from the funnel and place it on a blotting paper to remove excess water. Opti
48、onally, when the colorant under test is a vat dye, the filter fabric may be further treated, at this stage, in an evaporating dish and reducing solution followed by oxidation using the following procedure. a) Prepare 400 mi of a fresh reducing solution in an evaporating dish at 60 OC to 70 OC contai
49、ning: 1) 30 mVI sodium hydroxide (6.1); 2) 20 g/l sodium hydrosulfite (6.2). Fully immerse the filter fabric in the reducing solution in the evaporating dish for 5 min. Do not move the fabric during this time. b) Immerse the filter fabric for 1 min, without agitation in water (6.5) at 15 “C to 25 “C in an evaporating dish. c) Prepare 100 ml of an oxidizing solution in an evaporating dish at 40 OC to 50 OC containing 10 mill hydrogen peroxide (6.3). Fully immerse the filter fabric in the oxidizing solution in the evaporating dish for 2 min. Do not move
