Testing Fabric Characteristics
Write the correct characteristic for the testing method:
1. _____________________________
Grab a fistful of fabric and squeeze 20 seconds. Release and check for wrinkles. Shake the fabric several times of smooth it with your hand. Wait about 40 seconds. Are the wrinkles disappearing?
2. ______________________________
Does the fabric fall into soft, natural folds, indicating it drapes well? Hold the fabric between your hands. Mover your hands together whils slowly gathering the fabric. Are the folds sharp and crisp or soft and flowing?
3. ______________________________
Does the fabric resist tearing? High tearing strength is useful in children’s clothes, work clothes, and activewear. Make a scissors cut in the edge of the fabric. Then try to tear the fabric by hand. Does it tear easily?
4. _______________________________
Will knitted fabric keep its shape after wearing? Stretch a knitted garment with your hands, looking for reasonable resistance. If it stretches too easily, the shape may not come back, as on baggy sweater elbows and knees of pants.
5. _________________________________
Will the fabric allow air to pass through? Fabrics the “breathe” have high air permeability for more comfort in hot or humid weather. In cold or windy weather, fabric needs low air permeability. Hold the fabric tightly against your mouth and exhale. Evaluate the amount of pressure needed to blow air through.
6. __________________________________
Does light shine through the fabric? A fabric with low cover is somewhat translucent. A navy shirt shouldn’t show through when tucked into light coloured pants. Place a light coloured fabric over one with a darker colour. If the lighter fabric has adequate cover, the darker fabric won’t be visible.
