- Examples 1 to 4 had good flame retardancy.
- the basis weight of the knitted fabric was smaller than that in Example 1, and therefore the flame retardancy was insufficient.
- Comparative Example 2 the content of the flame retardant in the knit fabric, the fabric weight, and the fabric thickness have reached a certain level, but the coefficient is low and the synergistic effect of each factor is small. The flammability was inferior.
- a knit fabric was prepared in the same manner as in Example 1.
- the obtained knitted fabric was a knitted fabric with a basis weight of 313 g / m 2 containing 28% by weight of the halogen-containing fiber (A), 46% by weight of the cotton fiber, and 26% by weight of the polyester fiber (D).
