Question

write an activity to compare the water absorbing capacity of various clothing material​

Answer 1

Answer:What You Need:

12” square samples of cotton and nylon

4 oz glass

8 oz glass

Water

What You Do:

Have your child pour water into the large glass until it is ¾ full.

Ask him to saturate the wool sample with water.

Invite him to pull one corner of the cotton sample into the small glass, so that it is resting on the rim.

The experiment should be left in place for about 12 hours.

Encourage your child to observe what has occurred. If the experiment went as planned, some of the water probably flowed from the larger glass into the smaller glass.

Repeat steps 1 through 4 with the nylon sample.

Ask your child to notice the results. Which fabric produced the most water in the smaller glass? Which fabric produced the least?

What's Happening?

What has this experiment taught your child about the properties of synthetic versus natural fibers? Natural fibers tend to be more absorbent than synthetic ones. Cotton, for example, has more naturally occurring places that can form bonds with water molecules. This means that it can absorb a significant amount of water, about 25 times its weight! Nylon, on the other hand is not hydrophilic (a highly absorbent fiber), and can only hold about 10 percent of its weigh tin water.

Answer 2

An activity to compare the water absorbing capacity of various clothing material​

• Take equal-sized and -thickness pieces of cotton and polyester clothing. Place each article of clothing in the petridishes and weigh it separately. The textile scraps should be submerged in water for two to three minutes. Now remove each piece one at a time, then weigh it once more in the petridish.
• In compared to all materials, wool fabric has the lowest water absorption rate, whilst undyed Coolmax fabric has the greatest rate.
• Approximately 125 percent of their own weight in water was absorbed by the pure materials (100 percent Cotton, 100 percent Polyester, and 100 percent Rayon), which absorbed more water than their own weight. The mixes, on the other hand, absorbed roughly 85% of their own weight in water and absorbed less water than their own weight.
• The best water-absorbing fabrics in this comparison are cotton, linen, and silk, which should fall somewhere in the middle.
