Washing color fastness tester principle and technical characteristics

There are two kinds of washing color fastness testers: single cylinder and double cylinder, which can not only test the color fastness of washing, but also dry cleaning color fastness test
.

Instrument design parameters comply with both ISO, BS, AATCC, JAS, and SDC standards
.

The instrument is made of stainless steel, equipped with a program timer, digital temperature controller, water valve and washing tank equipped with convenient and safe lock switch, easy to
operate.

Safety devices: water shortage alarm, over-temperature alarm, door opening alarm, test completion prompt
.

Special anti-rust device with a speed of 40 PRM and an operating temperature of up to 95 °C
.

Wash color fastness tester is Shanghai Qianshi Precision Electromechanical Technology Co.
, Ltd.
independent research and development and production of testing equipment, cost-effective, after-sales service is complete, mainly for the textile water resistance, dry cleaning resistance, soap washing, chlorine water washing after the color of the staining and fading stability and setting
.

It can also be tested for dyeing, bleaching and decontamination powder performance and sampling under normal temperature and pressure
.

This test is an accelerated test designed to understand the color change of the textiles under test in a short period of time, and each test is equivalent to about five lifetime washes after fading/discoloration
.

Test principle: The specimen is sutured together with the specified standard lined fabric, washed under certain temperature and detergent conditions, the specimen is completed by stirring with the detergent and stainless steel beads, and then cleaned and dried, and then the color change and the staining of the lining fabric are evaluated with the discoloration and staining of the stained fabric
.

Technical features: 1, solid state relay control heating tube, no mechanical contacts, temperature stability, no noise, long
life.

2.
Directly adopt gear transmission, the transmission is smooth and reliable, and it is convenient
to exchange for the test cup holder.

3, electronic tact switch, no mechanical contact, long life, good reliability, the panel is covered with waterproof film, water splashed on the panel, will not cause any impact
on the circuit.

4.
The program controls the temperature and time, and has the function of proportional-integral (PID) adjustment to effectively solve the temperature "overshoot" phenomenon
.

5.
The instrument comes with a preheating pot
