INTRODUCTION
1.Colorfastness to wash machine ,used for testing the washing color fastness for all kinds of color textile.
2.Consisting of a water bath containing a rotatable shaft which supports,radially ,
stainless steel test cup with a diameter of (75±5) mm and a height of (125±5) mm,of capacity (550±50 ) ml ,the bottom of cups being (45±10) mm from the center of the shaft.
3.Put the tested specimen,steel ball and detergent together into the test cup. Scroll through the spindle to make friction between the sample and steel ball. After specified time , take out the specimen and dry, compare to the standard color assessment card. According to the sample's color change to evaluate the colorfastness.
4.There are bench-top type ,upright type and portable type for your choice.
TEST PRINCIPLE
A specimen of the textile in contact with specified adjacent or fabrics are laundered,rinsed and dried.Specimens are laundered under appropriate conditions of temperature ,alkalinity,bleaching and abrasive action such that the result is obtained in a conveniently short time .The abrasive action is accomplished by the use of a low liquor ratio and an appropriate number of steel balls.
The change in colour of the specimen and the staining of the adjacent fabric or fabrics assessed by comparison with the grey scales or instrumentally.
FEATURES AND BENEFITS
1.Body with high grade stainless steel wire drawing process , attractive and durable.
2.Friendly control interface ,easy to operate.
3.High-precision temperature controller, separated control cabinet from test chamber.
4.High-precision timer,automatic alarm to remind.
5.Door safety switch, when it`s open,machine stops working to prevent scalding accidents.
6.Equipped with two types of steel cups to meet more standards.
7.Test cups with special design,easy to install and prevent lackage.
8.Security system : water shortage protection , overtemperature protection,earth leakage protection,over current protection, over voltage protection.
9.Alarm device : water shortage alarm, overtemperature alarm, door open alarm, ending alarm.
