Dry Wet Rubbing Friction Color Fastness Test Machine Manual Crock Meter

Description: 1. The main function of the instrument: The instrument is an integral design, mainly by the base, the friction transmission mechanism and the counter, the sample holder with the sample and sandpaper fixed on one side of the base, shake the handle so that the friction with white cotton cloth head to make provisions Stroke reciprocating motion, so that the white cotton cloth and the sample friction with each other, rubbing ten times observed and gray card with a gray card to assess the degree of adhesion on the stability of the fabric sample dyed or surface coating to judge for the material The evaluation and selection of reference data. The instrument is suitable for yarn, yarn-dyed, printing and dyeing textiles and toys, or all the fabric inside the product.

Specification:

Friction head diameter: 16mm ± 0.1 Friction head stroke: 104±3mm (AATCC standard) Vertical pressure: 9N ± 10% Friction head running speed: 104mm/min Number of reciprocating tests in one test: 10 times Instrument weight: 4.2kg Instrument size: 660mm x 160mm x 215mm Standards compliant: BS 1006 D02 ,ISO 105X12/D02 ,AATCC 8/165, JIS K6328, L0815, L1084

Application:

Respectively, and the fabric dry / wet white cotton rubbing , and then assess the situation staining white cotton with a staining gray card , resulting in the fabric resistance to dry / wet friction performance.

Steps:

1. Sample preparation 1.1 sample and standard friction white cloth to be Humidity in the environment of constant temperature and humidity. 1.2 When the sample has a variety of colors, should make all the colors are rubbed to. 1.3 If the color of a large enough area, they must be sampled separately. 1.4 Cut the sample, respectively, do dry rubbing and wet friction, should ensure that rub to all colors. 1.5 If the front and back of the sample is made of different materials, colors, rubbing fastness test should be done on both sides. 1.6 to do dry, wet rub fastness should not be repeated in the same part of the sample. 2. Dry rub 2.1 The sample is placed flat on the friction sandpaper coated with sandpaper so that the direction of the sample length and direction of the instrument consistent with the fixed specimen in the platen, folder-like should be smooth. 2.2 The standard friction white cloth fixed on the friction head, with a spring clamp clamping, the friction head light on the sample; 2.3 should ensure that the sample without friction when sliding or wrinkling; 2.4 at a rate of once per second rub the arm 10 laps, the friction arm back and forth 20 times friction; 2.5 Remove the standard friction white cloth, rating. 3. Wet friction 3.1 completely wetted in distilled water standard friction white cloth; 3.2 After removing the folder squeezed in the filter paper, so that it has a certain moisture content; 3.3 The remaining steps with the above steps of dry friction; 4. Results processing 4.1 Before rating, use a light adhesive to gently rub the loose fluff on a white cloth. 4.2 with three layers of unused white cloth pad friction to be assessed under the white cloth, rubbing gray cloth with reference to assess the degree of staining cloth white cloth.
