Depending on the situation, most of them will be pilling. On the tag, 100% wool clothes pilled once and 30% wool clothes pilled twice. Wool and acrylic fiber will definitely pilling, as long as there is chemical fiber, wool will pilling if it is not worsted. Generally, worsted wool is soft and will not pilling. If it is cashmere, it will definitely pilling, and only real cashmere will pilling.

There are many factors leading to wool pilling:

Raw material factors: the higher the quality of wool raw materials, the better the fineness, the denser the surface scales, the better the curl, the softer the hand feel, and the easier it is to tangle, pilling and pilling;

Different knitting structures (plain needle, gold ingot, double gold ingot, etc. ) and different densities (loose and tight) can also cause different degrees of pilling and pilling on sweaters. The pilling test conducted by the State Bureau of Technical Supervision is based on different wool specifications (count) and woven into specified specifications and densities. Put the knitted structure samples into the pilling box for testing within the specified time, and then score them.

When wearing a sweater, contact with different objects (smooth and rough) will also produce different degrees of pilling, such as sleeves, pockets and other parts, which are most prone to pilling due to frequent friction;

Technically speaking: if the twist is loose, the wool is round and fat, and the strips are dry and plump, it is easier to pilling, but if the twist is tight, it will lose the style of wool and have no feeling of rope;

Therefore, the pilling phenomenon of sweater will be obvious in the initial wearing process, which can be repaired with small scissors and will not happen again, and this phenomenon will gradually disappear.

Extended data:

Some people think that as long as the pilling wool is not good wool, it must be wool with quality problems. In fact, this is a common prejudice. In the process of using all kinds of fiber clothing, due to the friction of various external forces, the clothing surface will pilling and pilling.

A kind of "wool" which is hard to see with naked eyes is produced on polyester clothing fiber, and it is rubbed and pilled when worn. This phenomenon is inevitable in natural fibers and chemical fiber fabrics, and it is still an unsolved technical problem in the world.

Wool fibers vary in length, and the longer fiber ends will be pilled after contraction. Generally speaking, sweaters with plain stitches and fish scales are not easy to pilling, while sweaters with single side, plain stitches and density are easy to pilling. ?
