Sweater suppliers&Factory Science: Why do knitted sweaters pilling? Is it a quality problem?

Sweaters are a must-have item in wardrobes. For various reasons such as fashion or warmth, sweaters will come in handy on various occasions. At this stage, sweaters have become a fashion statement and an indispensable part of the popular and "fashionable" crowd.

Regardless of the purpose of wearing a sweater, people often find that their favorite sweater will pilling. The sweater after pilling looks very old or feels worn for a long time, which affects the appearance.

These pilling phenomena can be found on almost any kind of sweater, but they are more common on acrylic, cashmere and wool sweaters.

Some types of fibers and fabrics are easier to pilling than others, but sweater pilling is usually normal and not a quality issue. It is inevitable for natural fiber and chemical fiber fabrics, and is currently an unsolved technical problem at home and abroad.

Sweater pilling is actually caused by the friction of the clothes themselves. This is why pilling is more likely to occur in the armpits or neckline.

These small balls that have been formed will continue to rub against the surface of the fabric, causing more pilling. We know that sweaters are formed by knitting yarns and then stringing them together. Once friction is encountered, some fibers may twist and attach to other fibers nearby, forming small balls.

The number of balls on the sweater also depends on the strength of the fabric. The stronger the fabric, the less likely the fibers will be rubbed and twisted by friction. So cheap cashmere fabrics are easier to pill than expensive cashmere fabrics.

The factors that cause sweater pilling are multi-faceted, mainly summarized in the following aspects:

1. Sweater materials: the higher the quality of wool raw materials, the better the fineness, the denser the scales on the surface, the softer the feel, but it is easy to entangle and pilling. Different twists of the yarn will also have different pilling phenomena.

2. Fabric structure: sweaters have different weaving structures (single-sided, Siping, fish scale needles, ingot needles, double ingots, etc.), and different densities (loose and tight) will also produce different degrees of pilling.

3. Wearing scene: When wearing, contact with different objects (smooth and rough) will also produce different degrees of pilling. Sleeves, bag openings and other parts are often susceptible to pilling.

The wool material can be improved from the process. At this stage, the anti-pilling technology is also updated at any time. Many wool materials on the market are marked with anti-pilling function. Choosing anti-pilling wool is not impossible to pilling. Wool is not easy to pilling.
