Pocketing Fabric for Uniforms: What to Specify

What pocketing is and why it gets its own spec

Pocketing is the fabric sewn into the inside of a pocket: the bag your hand and keys sit in. It is hidden, so it is easy to treat as an afterthought and buy on price alone. But a pocket takes constant rubbing, holds weight and is washed with the garment every time, so it is one of the first places a cheap uniform shows wear.

It is also a small part of the cloth requirement per garment. That is exactly why it is worth specifying properly: the saving from a poor pocket cloth is tiny, and the cost of a garment that comes back for a torn pocket is not. Our guide to fabric consumption by garment shows how little cloth the pocket bags take compared with the shell.

Why poly-cotton is the usual choice

Most pocketing is a plain weave in a polyester-cotton blend. Polyester brings tensile and abrasion strength and keeps the cloth from shrinking much. Cotton adds softness and absorbency, so the pocket feels comfortable and does not feel slippery against the hand. The blend ratio varies by maker, so ask for the written percentages, the same way you would for the outer cloth. The reasoning behind the usual split is the same as in why 65/35 poly-cotton shirting works for the shirt.

A plain weave is used because it is flat, stable and cheap to make. Pocketing is generally a light to mid-weight cloth, often somewhere around 90 to 140 GSM, but there is no single standard, so confirm the weight against the garment maker's own spec.

100% polyester, poly-cotton or 100% cotton pocketing

For most uniform programs poly-cotton is the safe middle. Choose 100% cotton only where the shell cloth is also cotton-rich and a soft hand matters most.

What to specify, and why each point matters

Treat pocketing as a short spec of its own, not a line in the shell cloth order.

Our guides on fabric shrinkage and key fabric tests explain how each of these is measured, including seam slippage.

Matching pocketing to the outer cloth

Shrinkage is the point that catches buyers out. If the shell cloth has been pre-shrunk and finished to low shrinkage and the pocketing has not, the two move differently in the wash and the garment distorts at the pocket. Ask for shrinkage figures for both cloths and keep them close.

Shade needs the same care as the outer cloth. If you are running a multi-year program, the pocketing shade should be held against an approved standard just as the shell is, so reorders stay consistent. See dye-lot consistency for how that standard works. Where the garment is light in colour, a white or very pale pocket usually avoids the show-through risk entirely.

Checking pocketing on delivery

Pocketing arrives in rolls like any other cloth, so it should be checked like any other cloth: width, weight against the spec, shade against the approved sample, and a look for defects. A quick wash test on a sample, measuring change against the shell, catches the shrinkage mismatch before it becomes a thousand puckered trousers. The same process applies as in how to inspect uniform fabric on delivery.

FAQ

Frequently asked questions

What is pocketing fabric made of?

Usually a plain-weave polyester-cotton blend. Polyester gives strength and low shrinkage, and cotton gives softness and comfort. The exact ratio varies, so ask for the percentages in writing.

How heavy should pocketing be?

It is a light to mid-weight cloth, often around 90 to 140 GSM, but there is no single standard. Confirm the weight against the garment maker's spec and check delivered rolls against it.

Why do trouser fronts pucker after washing?

A common cause is a pocket bag that shrinks more than the outer cloth. The bag pulls the panel it is sewn to. Specify shrinkage for the pocketing as well as the shell, and keep the two close.

Does pocketing need to match the colour of the outer cloth?

It should either match the shell or be white or very pale, so it does not show at the pocket mouth. It should also be colour fast to washing and rubbing so it does not bleed onto skin or other garments.

Can I use the same cloth for the pocket as for the garment?

You can, but shell cloth is heavier and costlier than a pocket bag needs. A purpose-made pocketing cloth is lighter and cheaper, and the trade-off is that it must be specified and matched with the same care.
