A new summer denim quality we introduced this summer is a 12Oz Japanese Neppy selvedge denim from Collect ( the fabric mill from Japan Blue ) .
When a garment is neppy, or has nep, it usually just means that the fabric of the garment has been woven in a way that some of the cotton fibers extend and protrude from the main surface. Usually these fabrics tend to posses a “snowy” look, as if fresh fallen snow is sitting on the surface of the denim. The texture in this type of denim will be more noticeable on the surface of the fabric than the peeking glimpses of white in the composition of a slubby fabric.
Nep denim also possesses some peculiar traits throughout life of the fabric. It still fades naturally like most raw denim, but the neppy fibers will become more pronounced in the appearance of the jean; bringing about a furrier look. One of the most desirable features of a nep denim is their uncanny ability to fade horizontal, as well as vertically like the snowy nep denim below.
Loom chatter also plays a role in the production of nep denim. As noted neppy denim usually has visible fibers exposed from the main surface of the fabric; fibers which are usually knots and broken fibers within the yarn that occur as it is spun and then woven. Loom chatter exacerbates the nepping process by further agitating the fibers and leaving them more exposed through the shaking and tangling of the yarn while the loom weaves.
This season we made our Combat Blazer & Pants in this fabric :
