Wet and dry friction color fastness testing machine
1 the main function of the instrument is introduced
the instrument is an integral design, mainly is composed of a base, a friction drive mechanism and a counter, with sample holder will sample sandpaper and fixed at one side of the base, the handle is shaken filled with white cotton friction head to the reciprocating motion of the provisions of the trip on the specimen, specimen and the white cotton cloth to make the mutual friction, friction ten times after observation and gray card comparison white cotton stick color degree assessment, judge the stability of the fabric sample dyeing or surface coating, so as to provide reference data for the evaluation and selection of materials. this instrument is suitable for all kinds of fabric, yarn dyed, printing and dyeing textile and toy products or on the inside.
this instrument meets the following standards: BS 1006 D02
K6328 L0815, JIS, L1084

1 sample preparation
1.1 samples and standard white cloth friction in constant temperature and humidity environment humidity.
1.2 when the sample has a variety of colors, should make all the colors are friction to.
1.3 if the area of a variety of colors is large enough to be sampled separately.
1.4 shearingsample respectively, dry friction and wet friction, friction should guarantee to all colors.
1.5 if the positive and negative samples are made of different materials, colors, and the negative side to do the color fastness test.
1.6 do dry, wet rubbing fastness should not be repeated in the same part of the test specimen.
2 dry friction
2.1 will flat specimens put on paved with sandpaper friction instrument, sample and the length direction of the instrument's dynamic process in the same direction and fixation of the specimen in the platen and clamp sample should be flat.
2.2 the standard cloth is fixed on the small friction friction head, clamping spring clamp, the friction head light on the specimen;
2.3 to ensure that the friction when the specimen without sliding or wrinkling;
2.4 at a rate of 10 times a second shaking the friction arm, so that the friction arm back and forth friction 20 times;
2.5 remove the standard friction small cloth, rating.
3 wet friction
3.1 in distilled water soaked completely standard friction small cloth;
3.2 after removing the filter paper clip in the squeeze, so that it has a certain moisture content;
3.3 the remaining steps with the above dry friction steps;
4 treatment results
4.1 rating before use transparent glue stick to loose hair gently rub on a piece of white cloth.
4.2 three did not use rubbing cloth pad in the assessment of the friction cloth to be, the reference standard staining gray card evaluation of friction small white stain grade.
Because the supplier might will revise product packaging, origin, manual or accessories etc. without notice in advance, our company will not ensure that the product you received will be completely the same to the mall pictures and accessory specifications on website. but our company confirms that the product you received is high quality product from original product supplier!
