I am far from a suit expert, but I have owned suits before that I am pretty sure were 100% wool. I have never had problems with them attracting and hanging on to large amounts of pet hair.
I just purchase several suits from a place that said their suits were 100% wool, but after wearing them for a few days, I am definitely noticing a difference in how pet hair clings to them. I’m looking down at my pants and thinking I am going to need to buy a lint roller and bring it to work.
Isn’t that a indication that they have a substantial amount of polyester in them? Is there any way I can tell? Did I get ripped off?
PS. I did get the suits from Jos. A Bank (maybe that will help the discussion), but I am not interested in a Jos. A Bank vs other suits argument. I am looking for a factual discussion.
I think your method of proof/investigation is off. I can’t believe pet hair clings to polyester more than wool: the materials work to the contrary. Polyester cloth is very very smooth, so the physical trapping of hair is far less, and I believe has little or no ability to store static charge (although I’m sure others can correct me or go into details better than I can on that).
I am not an expert in fabric but there is not just one type of wool fabric. The weave, texture, and fiber quality probably all come into play for how fabric grabs or sheds animal hair. I have several pairs of pants and suits that are 100% wool (many of them are Jos. A. Bank) and the surface texture varies quite a bit. Summer-weight wools can be quite fine and silky. Some heavier fabrics or weaves can be quite coarse, and I would imagine they are more prone to grabbing hairs. I am also guessing that there is a difference in the wool fiber itself but my experience is that Jos. A Bank uses pretty good materials. I don’t have pets anymore so I can’t speak specifically to the hair issue.
Wool varies a LOT, and how it is prepared and spun also varies. Very fine, tightly spun, long fiber wools tend to be smooth. But other wool can be coarser, ‘hairy’, or short in fiber. Any wool can be loosely spun, and if it is loosely spun, or hairy, or short-fiber (which causes more ends to be sticking out), it may grab onto dog hairs.
You can even spin wool to be visibly shaggy.
