UNE-EN ISO 105-D01:2010

A test piece of the textile, in contact with a specified control fabric or fabrics, is placed inside a cotton fabric bag together with stainless steel discs and shaken in perchlorethylene; then it is squeezed or centrifuged, and dried with hot air. The degradation of the color of the test piece and the discharge on the tissue or tissues is evaluated taking the original test piece as a reference, with the help of the gray scale or instrumentally.

• Perchlorethylene
• Control tissues
• A control multi-fiber fabric, type DW or type TV, in accordance with ISO 105-F10 Standard.
• Cotton twill weave, bleached, undyed, unsized
• Corrosion resistant (stainless) steel discs
• Grayscale to assess degradation
• Gray scale to evaluate the discharge
• Appropriate mechanical device, consisting of a water bath fitted with a rotating axis that carries, radially arranged, several stainless steel containers of (75 ± 5) mm in diameter and (125 ± 10) mm in height, with a capacity of (550±50)ml

• A 100 ± 2 mm x 40 ± 2 mm test piece is attached to a multi-fiber control fabric sample, also of dimensions 100 ± 2 mm X 40 ± 2 mm, by stitching along one of the short sides, the multi-fiber fabric being placed in contact with the upper face of the test piece.
• A 100 ± 2 mm x 40 ± 2 mm test piece is placed between the two control monofiber fabrics, also with dimensions 100 ± 2 mm x 40 ± 2 mm, sewing all three with a seam along one of the short sides.

• The mechanical device is prepared by heating bath water to the working temperature of 30 ± 2 ºC.
• A bag with internal measurements of 100mm x 100mm is made using the undyed cotton twill fabric by sewing two cotton twill squares together along three sides. The composite specimen and the 12 steel discs are placed inside the bag. The bag is closed, using an appropriate medium.
• Steel containers are removed.
• The bag containing the composite specimen and the steel discs is placed inside the container.
• 200 ml of perchloroethylene are added inside each of the steel containers at 30 ± 2º C
• S starts rotation for 30 min.
• The cylinder is removed, placed between two layers of white absorbent paper or tissue, and squeezed, or centrifuged, to remove excess solvent.
• The color degradation of the test tube is evaluated and is discharged on the control fabric by comparison with the original test tube using the gray scale.
