You're washing your sweaters without doing this first.
洗毛衣前沒有先翻面

According to CottonWorks, you should always wash your sweaters inside out to prevent pilling. The rubbing that occurs during washing can cause textiles like wool and cotton to rub against each other and bunch up, creating unsightly pills. In fact, if you looked at wool fibers under a microscope, you'd see that they're actually covered in tiny scales. These scales can catch on each other and cause pilling, so flip your sweaters inside out before cleaning them.

CottonWorks網(wǎng)站稱，你應(yīng)該總是將毛衣反面洗滌，防止起球。清洗時(shí)的摩擦?xí)屟蛎?、棉等面料的織物互相摩擦產(chǎn)生難看的毛球。事實(shí)上，如果你用顯微鏡來看羊毛纖維，你會(huì)看到纖維實(shí)際上被小鱗片覆蓋。這些鱗片會(huì)彼此糾結(jié)在一起，起球就是這么產(chǎn)生的。所以在洗毛衣前記得先翻面。

You toss your bathing suit in the dryer.
將泳衣放入烘干機(jī)內(nèi)

As a general rule, lace, silk, and beaded fabrics should stay out of the dryer and be laid flat to dry on a rack. The elasticity of swimwear can also be destroyed by heat, so dry your bathing suit on a rack as well. Hand-washing delicate items like bras and underwear is best, but you can also place them in a mesh laundry bag that will protect them from tangles and tears in the washing machine.

一般情況下，蕾絲、絲綢和綴珠面料都不能放入烘干機(jī)，而應(yīng)該平攤放在架子上晾干。泳衣的彈性會(huì)因受熱而損壞，因此泳衣也應(yīng)該放在晾衣架上晾干。文胸、內(nèi)衣等嬌貴服飾最好是手洗，但你也可以將它們放在網(wǎng)眼洗衣袋中機(jī)洗，保護(hù)這些衣服不被撕壞或纏繞在一起。

You're using the wrong kind of detergent.
用的洗衣液（洗衣粉）不合適

If you have a HE (High Efficiency) washing machine, you need to use the right kind of laundry soap. These types of washing machines use less energy and water to get your clothes clean, so they work best with low-sudsing HE detergent.

如果你有一臺(tái)高效洗衣機(jī)，你需要使用正確的洗衣產(chǎn)品。這類洗衣機(jī)更節(jié)能省水，所以最好和低泡高效洗衣液結(jié)合使用。

According to The Spruce, using conventional detergent in a HE machine can actually stop your clothes from being thoroughly cleaned and might result in detergent residue in your garments. Look for the HE logo on the detergent bottle to be sure you're using the best product for your clothes and machine.

The Spruce網(wǎng)站稱，事實(shí)上在高效洗衣機(jī)里用傳統(tǒng)洗衣液會(huì)阻止衣服被徹底清潔，可能會(huì)導(dǎo)致衣服內(nèi)有洗衣液殘留物。選購那些瓶子上有高效標(biāo)志的洗衣液，確保你用的洗衣產(chǎn)品適合你的衣服和洗衣機(jī)。
