Assertion: phosphoric acid's amount | /r/AtLocation | fiber raw material
Facets:
Source sentences:
text: The amount of compound A added to the fiber raw material is not particularly limited, but when the amount of compound A added is converted to a phosphorus atomic weight, the amount of phosphorus atom added to the fiber raw material is preferably 0.5 to 100% by weight, and preferably 1 to 50% by weight.
text: When the amount of phosphorus atoms added to the fiber raw material exceeds 100% by mass, the effect of improving the yield reaches a peak and the cost of the compound A to be used increases, which is not preferable.
text: On the other hand, if the amount of phosphorus atoms added to the fiber raw material is lower than 0.5% by mass, a sufficient yield cannot be obtained, which is not preferable.
