What role does the 'nep structure' mentioned in the denim description play in the fabric?
I asked this question after seeing an unfamiliar textile term in the product description, wanting to know how the fabric's surface texture and actual appearance differ.
By leaving tangled fiber clumps intact during spinning, it adds a texture that looks as if small, thick specks are scattered across the surface of the fabric[1].
Nep is a method of weaving tangled clumps of fiber into the yarn rather than picking them out completely during the yarn-spinning process. Unlike standard spinning, which smooths and evens things out, fine specks or cotton puffs appear bumpily on the surface.
MOONDAL gave this denim fabric a three-dimensional feel by naturally scattering the nep structure throughout the fabric[2]. The bumpy texture revealed on top of the deep blue base creates a texture that is far from flat[3].
It leaves bumps instead of smoothness. As friction builds up along the raised texture with wear, the color fades irregularly, further emphasizing the characteristic texture of denim.

The specific blend ratio and weight of the cotton yarn fabric that forms the nep structure have not yet been confirmed.
