Moisture resistant microbial penetration tester

Main USES:

The crease recovery Angle tester is suitable for testing any fabric made of pure fiber or blended fabric. It can be used to test the resilience of the sample after being folded and pressed for a certain time under a certain load.

Meet the standards:

AATCC 128, ISO 9867, ENKA 3061

Main parameters:

1. Sample size: 15cm×28cm(6×11 inches)

2. Weights: 2000g, 1000g, 500kg, 200kg, cumulative

3. Overall dimension: 150×150×330mm(6×6×13 inches)(length × width × height)

4. Weight: 9.5kg(21lb)

Crease recovery tester _ Wrinkle recovery Angle Main features of the tester:

1. The base with bracket, the circular steel plate fixed on the base is matched with the movable steel plate on the upper end, and the movable flange is equipped with locking pin;

2. 4 standard weights, respectively 2000g, 1000g, 500kg and 200kg;

3. Provide a full set of 5 "x 3" plastic sheets for easy rating (1-5).

Main principles:

Standard atmospheric conditions, using standard crushed device to sample a predetermined pressure, and maintain the stipulated time, the overall structure of the instrument and the precision of spiral column can assure the sample produce uniform deformation after loading, remove the sample from the instrument, to cut wet sample in the standard atmospheric conditions and to restore the certain time, then according to the contrast and reference samples, sample evaluation sample appearance.

Test process:

1. The three samples were tested consecutively with an interval of about 1min using a sampler;

2. Fold the sample face to face and clip the edge of the cloth, no more than 5mm of the edge of the cloth;

3. In some cases, the surface of the sample will stick together. A piece of paper or aluminum foil with the size of 18x14mm should be used.

4. Place the folded sample between two pressure blocks, immediately apply the weight, turn on the timing device, wait 60+2 seconds, and prepare the next sample according to 2, 3, 4;

After 5.5 minutes, quickly and gently remove * weights.

Use clamps to transfer the folded samples to the sample rack of the measuring instrument;

6. Remove the paper or aluminum foil, put one side of the sample into the sample clip, and hang the other side freely. After 60+2 seconds, put the second and third pieces into the sample clip;

7. Adjust the instrument to make the lower end of the sample suspension consistent with the vertical mark of the instrument, and adjust it continuously within 5min (make the lower end of the sample suspension consistent with the vertical mark of the instrument) to avoid the influence of gravity;

After 8.5min, the recovery Angle of the sample was recorded.

If the droop end is slightly curled or twisted, take the vertical plane through the droop end center and dial axis as the reference for crease recovery Angle reading;

9. Repeat the above steps, and make three samples of reverse folding and reverse folding in the latitudinal direction (12 pieces in total).
