Ibn Ganaḥ (in his Book of Hebrew Roots) says that kenaf is used in the sense of “concealing,” in analogy with the Arabic kanaftu alshaian, “I have hidden something,” and accordingly explains, Isaiah 30:20, “And thy teacher will no longer be hidden or concealed.” It is a good explanation, and I think that kenaf has the same meaning in Deuteronomy 23:1, “He shall not take away the cover (kenaf) of his father”; also in, “Spread, therefore, thy cover (kenafeka) over thine handmaid” (Ruth 3:9).
