Why new hemp clothing feels stiff

You just bought a shirt or bedding made of hemp and it seems like something is wrong with it? Don't worry: stiffness and slight scratchiness are the most common complaints on first contact with this material, not a product defect.

There are two reasons, both physically grounded:

• Residual pectins and waxes: incomplete removal during fiber processing, more common in cheaper, less refined batches.
• Natural stiffness of lignin: in hemp it is 3.5 to 5.5%, compared to 2.0 to 2.5% in linen, so you feel hemp as stiffer even compared to linen.

It's worth changing your perspective on this. Stiffness of new hemp clothing is not a permanent property of the material, just its initial state. Unlike many other fabrics in this material series, where stiffness can be a problem to solve once, with hemp it's a stage in the natural life cycle of the fabric that passes on its own with use and washing.

This topic is important enough to deserve its own, practical section. You will see in it the exact mechanism behind the stiffness, how many washes it takes, and how to safely speed up the process without damaging the fiber.

Hemp and linen are close relatives: both fibers belong to the so-called bast fibers, obtained from the plant's stem, not from seeds or fleece like cotton or wool. This kinship explains why the initial stiffness of both materials has the same cause, although in hemp it is more clearly felt.

Hemp fiber is built mainly of cellulose, surrounded by a natural binder made of lignin and pectin. Lignin stiffens the plant's cell wall so the hemp stalk can grow straight and tall without support. The same mechanism that keeps the plant upright in the field shows up in the fabric as noticeable fiber stiffness, until it is partially loosened during subsequent washes.

Pectins work somewhat differently: they glue individual fibrils into bundles during raw material processing. The more thoroughly the manufacturer removes them during retting and scutching, the softer the finished fabric feels from day one. Cheaper batches of raw material go through this process more superficially, which is why differences in stiffness between individual hemp garments are already noticeable on the store shelf.

Hemp fabric softening is more like a marathon than a sprint: it's a cumulative process, not the result of one magic wash. Washing several times in lower temperature, 30 to 40°C, softens the fabric in two ways. The first is rinsing out residual pectins remaining from fiber processing, the second is mechanical loosening of fiber structure with each cycle.

Below you will find four steps that describe this process from the first wash to stability of softness.

How many washes exactly does it take? In practice, you usually notice a noticeable change in softness after 5 to 8 washes at 30 to 40°C. After this stage, the fabric reaches its target softness and stabilizes, further washing no longer changes its texture as dramatically as these first few cycles.

If despite a dozen or so washes the fabric still feels stiff, or if it's a large piece, for example hemp bedding or a tablecloth, it's worth considering handing it to a professional laundry instead of experimenting at home. A skilled laundry matches temperature and program to the specific fabric, so softening progresses without the risk of over-drying or damaging the fiber with excessive heat.

The same applies when a stain or soiling appears on hemp clothing that you'd rather not risk removing yourself on fiber that is still stiff and less receptive to chemistry.
