Fabric Pilling Test with Pilling Box Method
Pilling Test with Pilling Box
Method (ISO: 12945-1)
Fabric Pilling Test
Objective:
To determine pilling resistant of given fabric.
Principle:
According to the movement of pilling box allowed to generate fabric surface
pilling of particular specimens.
Tools
and equipment: Marking pen, scissor, polyurethane
tubes, mounting devices, single needle lock stitch machine, pilling box.
Procedure:
Each specimen was cut using 125 mm x 125 mm template. In this specimen
preparation process, all diagrams were drawn on back face of given fabric. After
drawing, each panel were cut carefully and stitched by folding 12 mm by aiding
single needle lock stitch machine. After stitching turned sewn specimen to get
face area and each edge were cut as 6 mm to reduce sewing distortion. After
using metallic mounting devices, prepared samples were mounted on polyurethane
specimen tube and there were applied tape cover to avoid fraying edges of
composite specimen. And this covering application was wrapped additionally 1.5
cm area of circumference of specimen complex. And 6 mm was gap was taken from
each tube ends. Prepared pilling specimen on polyurethane tube were kept into
pilling box and launched pilling operation and according to ISO standard report
revolution were adjusted as below.
v For
woven fabrics: 5 hours 18000 revolution
v For
knitted fabrics: 3 hours 10800 revolution
v Recommended
round per minute value: 60 RPM
After completion of
pilling test all stitch applied were removed and separated specimen from polyurethane and passed to the assessment process.
Assessment:
After practical practical test, output specimen was inspected in assessment box
with proper lighting in dark chamber. And samples were assessed using 1 to 5 grades
and those are given below table.
