When designing for disassembly in the textile sector there are multiple challenges. For example yarn blends that make separation of the fibres difficult, coatings and haberdashery. This time I would like to share with you some alternatives for haberdashery.
Could you reconsider the function of haberdashery?
Reframe the design task. For example, you do not always need a zipper, you need something to temporary attach two fabrics together in an easy way so they can be separated and reattached in a short period of time. And when you want to recycle the fabric the haberdashery needs to come off easily.

Freitag has a button that can be screwed off, so simple, yet so effective! Although it needs to be manually screwed off, which is labour intensive it is a good example of an easy fix.
(Nice book on the creation of the brand Freitag)

Wear2 yarn can be used to attach haberdashery and easily disassemble them. But at the moment this is yet to expensive for the industry to use it regularly.

Sometimes folding a fabric is enough instead of using a zipper or button. For example with pockets, like Laladoo does with their Kimo design.

Look at ways how bags are closed like this Building Block bag.

Design for disassembly is not always needed.
For example when you use a 100% polyester fabric you could use a 100% polyester zipper (at the moment mostly parts of the runner of the zipper are still of metal) and then both can be melted into polyester granulate for new products.
