1. factors affecting woolen sweater lifting

The length of the fibers in the wool is caused by the shrinkage of the ends of some fibers. The fabric structure of woolen sweater is different, and it will produce different degree of ball phenomenon. Generally speaking, the four flat needles and fish scales are not easy to pilling, and the single side and flat needles are easy to pilling, and the density is loose and easy to pilling. The raw material factor of wool sweater is that Australian wool has good fineness, soft handle and easy pilling, and domestic wool has poor fineness and handle, so it is not easy to pilling.

2. choose the woolen sweater that is not easy to pilling.

In general, fine needles and fine count yarns are usually used for weaving. The thicker needles, coarse yarns and loosely knitted sweaters are not easy to pilling, and the handle is tight and fluffy. When the wool is spinning, the yarn twist of the yarn is relaxed because of the soft feel of the wool yarn, so that the fiber is relatively loose. When the sweater is rubbed, the short fiber will slip away from the yarn and form a ball.

Only with a tight twist, the pilling phenomenon will be less, but the sweater's feel will be stiff. Some thin sweaters are mostly plain knitted sweaters, and the needle rings are loose and easy to pilling. Most of the thick spots are Siping, the density of the needle ring is tight, and the fibers are tightly interlocked. After the yarn is rubbed, the fiber slips relatively little from the yarn, so it is not easy to pilling.

3. pilling maintenance of cardigan

To reduce pilling, we should pay attention to reducing the friction between the surface and rough objects. Some areas where friction is more likely, such as sleeves and desktop, sofa handrails, inner bags, wallets, and long backpacks, wear rough coats without lining, especially pilling, should minimize such contacts.

Secondly, the sweater pilling does not affect the quality. The new sweater has a slightly higher pilling phenomenon at the beginning of the dress. It can be cut off with a small scissors, gently removed by fingers, or shaved by a special electric shaver, and then gradually reduced and weakened. For larger pilling balls, the sweater can be spread evenly on the flat table top, and the brush is used to brush the dust lightly with the stitches of the fabric, straighten and tighten, use a special electric shaver to gently and vertically suction, shave the ball, brush the brush, and then scald it with a steam iron, and immediately clean and neatly, which will not damage the woolen sweater.
