silk
絹 centers on silk as a material: the fine, lustrous fiber produced by silkworms and the fabric woven from it.
絹 combines 糸 (thread) with 肙, which likely contributes the sound and may relate to a small worm or insect, fitting the silkworm origin of silk.
The left side is thread 糸, and the right side 肙 looks like a little worm with a mouth 口 and body 月. Picture a silkworm spinning fine thread to make silk.
For ケン, imagine a silkworm named Ken spinning silk: Ken -> ケン, and his thread becomes the finest silk.
