Wordpress WooCommerce filter by part attribute?

Is the attribute containing something like the following:
18% viscose, 80% polyester, 2% elastan
20% wool, 70% rayon, 10% lycra

It is necessary that the filter can filter according to, respectively:
viscose, polyester, elastan, wool, rayon, lycra.

In other words have issued the goods to the attribute which contains for example "wool".
I searched through all the possible plugins and did not find how to configure it. Painfully do not want to introduce a new attribute and edit all items.

About the attributes do not know, but filtering part of the article (_sku) makes the plugin WOOF
hmm... might have missed it... I'm gonna check this plugin carefully. - maritza_Ferry commented on March 23rd 20 at 19:43
