Fluff retention test of pile fabrics

The pile retention properties of pile fabrics refer to the ability of cut pile pile fabrics to maintain their piles without falling off under repeated mechanical friction with abrasive paper. The pile retention of pile fabrics can be tested by weighing method (Method A) and light transmission method (Method B) to determine the pile retention of pile fabrics.
Zhongke Testing Environmental Reliability Experiment Center has the ability to test the reliability performance of various textile raw materials and products, and provides professional down retention testing services for pile fabrics.

Pile fabric pile retention test is suitable for cut pile and raised fabrics, but is not suitable for brushed and raised fabrics, carpet fabrics and flocked fabrics.
According to the formation method of pile, it is divided into: pile knitted fabric (knitted flannel), cut pile knitted fabric (including velvet fabric, velvet fabric), cut pile knitted fabric and knitted artificial fur.

After the pile fabric is subjected to repeated mechanical friction with the grinding paper, split the yarn in the unworn fabric in the same area as the worn part, weigh it, and calculate the pile retention rate based on the weight change of the fabric pile before and after grinding (A method) or observe the degree of light transmission of the worn part of the fabric due to the shedding of the pile, and determine the pile retention grade based on the number of frictions and the pile retention grade table (Method B).
