FAQs & Answers
- What is the importance of calculating fabric shrinkage? Calculating fabric shrinkage is important because it helps manufacturers and consumers understand how much a fabric may shrink after washing, ensuring proper fitting and preventing issues in garment production.
- What types of fabrics are more likely to shrink? Natural fibers like cotton, wool, and linen are more likely to shrink due to their absorbent properties, while synthetic fabrics like polyester and nylon generally have lower shrinkage rates.
- Can you prevent fabric shrinkage? While complete prevention is challenging, pre-washing fabrics before sewing, using cold water for washing, and air drying can significantly reduce shrinkage.
- How do you know if a fabric has already shrunk? You can test if a fabric has shrunk by measuring its length and width before and after one wash cycle, comparing the measurements to determine if there is any shrinkage.
