Question

Which of the following is true for lyocell: (2 points) A. Exhibits progressive shrinkage B. Poor moisture absorbency C. Problem with fibrillation D. Poor electrical conductivity

Answer 1

Among the options, the correct statement about Lyocell is that fibrillation can be a problem if not properly treated. While it may shrink under certain conditions, lyocell is not characterized by progressive shrinkage, and it's known for good moisture absorbency and generally poor electrical conductivity.

Step-by-step explanation:

The question relates to the properties of Lyocell, a semi-synthetic cellulose fiber. Of the options presented:

1. Lyocell doesn't necessarily exhibit progressive shrinkage, but it can shrink when washed or heat-treated.
2. Lyocell actually has good moisture absorbency which makes it breathable and comfortable for wear.
3. There may be a problem with fibrillation (the peeling of fiber surface) with lyocell if it is not treated properly, making this choice the true statement.
4. As for electrical conductivity, this is not usually a considered property of textile fibers, including Lyocell. But in general, it should have poor electrical conductivity, given its organic nature.
