Testing the pilling behavior of knitwear with the circular path method Pilling Tester معدات اختبار

Product Description:

There are many types of knitted fabrics. During the actual wearing and washing process of knitted fabrics, due to the continuous friction, the fibers on the surface of the fabrics are exposed on the surface of the fabrics, and wool appears on the surface of the fabrics. This phenomenon is known as “pilling”. If these hairs cannot fall out in time when worn continuously, they will tangle with each other and knead into many small spherical particles, which is commonly known as \"pilling\". These hairballs protruding from the surface of the fabric are very easy for dirt and dust to adhere, which greatly affects the wear resistance and appearance of the fabric.

Under normal circumstances, there are four main test methods for fabric pilling: random reverse pilling test method, abrasion test methodon Martindale, the roller box pilling method and the circular bottle pilling methodformer. here, Shanghai Qianshi mainly introduces me to the orbit.

Test Pattern:

Polyester Knitwear- cotton

Test procedure:

1. Sample production:

(1) Pre-treatment: If pre-treatment is required, the sample may be washed or dry-cleaned according to the procedure agreed by both parties. (In order to protect the friction surface of the pilling box and sample tube from the influence of stains or finishing residue on the fabric, pre-treatment is recommended)

(2) Cut from the fabric swatch 4 swatches from the top, the size is 125mm x 125mm, and another piece of fabric swatch of the same size is used as the swatch. comparison for evaluation. 2 bosseshave folded inwards along the longitudinal front and 2 patterns are folded inwards along the transverse front and sewn with the sewing machine at a distance of 12mm sewn from the edge.

(3) Turn the sewing pattern over so that the front is facing out. Cut the 6 mm ports at the lower ends of the sample tube to eliminate seam distortion. Place the sample on the polyurethane sample loading tube and secure it with PVC tape (ensure that 6mm of both ends of the polyurethane are exposed and that the length of the tape does not exceed 1.5 times the circumference of the polyurethane tube).

2. Test steps:

(1) Clean the pilling box;

(2) Put 4 sets of planting tubes into the box, close the lid of the box tightly, and set the counter to the required number of turns;

( 3) Preset number of turns. numberof agreements. If they do not match, we spin the woolen fabric 7200 rpm and the fine imitation 14400 rpm;

(4) Then start pilling The test is completed, take the sample outside and outside seam, for sample evaluation.

3. Pilling degree rating:

Compare the rating under the standard light source with the standard photo, that is, let Your multi-rater compare and analyze the sample with the standard photo in the assessment box and use the result as the sample\'s pilling level. The photo method example assumes five ratings, each ranging from 1 to 5. The lower the grade, the stronger the pilling and the better the anti-pilling performance.
