After wearing and washing my knits and sweaters several times, they start to pill easily. This can also be said to clothes that are felty. Is there any way to prevent this pilling without using a remover or is it inevitable? I wash them in the bags. The reason why I don't wanna use a remover is because I once accidentally tore a knit. Since I wear my favorite ones more often like many people would, it happenes more to these favorite ones and it's so annoying!
Water-efficient vertical drum washers, I find, are much gentler on fabrics than the horizontal washers. This is probably because the impeller in the older washers caused friction between layers of fabric, while the tumbling action of vertical machines causes less rubbing.
In any event, use the least detergent, least water and shortest cycle. Hand-washing with mild detergent such as Woolite was once required, but the HE washers seem just as mild.
After much wear, even without washing, though, some yarns pill.
Pilling of fabric occurs during wear more than by care.
Washing loostens the fibres in some fabrics by removing the "sizing" (a kind of starch) used to give "body" to most flat fabric finishes during their manufacture. While you cannot replace the sizing in the fabric, you can avoid strong detergents and fabric softeners that hasten the softening of the fabric finish. Avoid tumble drying.
Since pilling occurs when two surfaces rub against each other, avoiding that will reduce pilling.
Going further; the removal of the pills as soon as you can will help reduce their numbers but I have NO practical evidence of this
Wash "pill-friendly" items separately!
If grouping several of these items in one wash:
- make sure these are the only items in the wash
- (REVISED) for sweaters, use mesh bags designed for washing delicates (use larger size mesh bag meant, say, for a blouse instead of lingerie); one item per bag)
- hang to dry, or dry flat (sweaters) - do not put in the dryer (these fabrics tend to shrink in the dryer and the fluff/friction action in a dryer tends to encourage more pills to form)
Hope this is helpful!
