Identifying Unknown Fibers in Your Stash

by

yarn burn testYesterday we looked at our odd balls and organized in terms of yarn weight. Maybe you already have an idea of some yarns that you’d like to go together in a project. If so, that’s awesome!

But sometimes you need a little more information about a yarn before you dive into using it. And with unlabeled balls the thing you may still want to know is what kind of fiber you’re dealing with.

Sometimes you can tell a bit by touch — at least enough to know if something is a natural on manufactured fiber. Sometimes you can tell cotton (or at least something in the cotton/hemp/linen family) by the feel, and you can often feel something and know it’s made with at least some animal hair. stash busting

There’s no 100 percent surefire way to determine what every unlabeled yarn in your stash is, mostly because there are probably blends, and a lot of the fibers react in a similar way when you test them.

The most common test for determining what kind of fiber you’re dealing with in known as the burn test, because you set the yarn on fire and see what happens.

Of course you’ll want to do this in a safe place, away from children and animals, with a protected surface and using only a small sample of the yarn.

Set it on fire (I use a long lighter) and observe. What happens to the fiber? Does it burn or melt? Natural fibers (and rayon, since it’s made from wood) will burn, while acrylics and synthetics melt. How does it smell? Wool and the animal fibers smell like burning hair, as you might imagine, while cotton yarn and similar fibers smell like paper or leaves. The manmade fibers can smell anything from vinegar to fish to chemicals, and they usually give off black smoke and leave behind various interesting residues.

I’m not a huge expert on burn testing, so if you want to try it for yourself you’ll want to check out more detailed information at FabricLink and Fiber-Images.

If you’re still wondering what something is, or you just don’t want to go to the bother of testing, assume what you have before you is not machine washable. Or knit a swatch (which uses more yarn, yeah!) and launder it the way you might want to launder something made out of the yarn. If it felts or something else drastic happens, you’ll have learned something valuable even if you don’t know exactly what the fiber is.

Have you tried a burn test or another method to learn about a mystery fiber? I’d love to hear about it!

  1. My mom taught me about this, but then, she’s got a degree in chemistry. Whenever I try it myself I end up getting flustered and and up not noting the crucial bits.

    It’s fascinating stuff though.

  2. I have used the cholorine bleach test on yarn. Wool or animal fibers will completely dissolve in a couple of minutes. Pour a small amount of bleach in a small glass dish and cut 2 or 3 inches of the yarn and just drop it in it the dish. If it doesn’t all dissolve, it is a blend.

Bucket Hat Knitting Patterns

As I was starting to write this post I thought that it was true that I’d never done a roundup of bucket hat knitting patterns before. But then I looked, and I actually did one last year (which you can find here) but there are plenty of cute bucket hats to do another post about, right? 

The one that made me want to write about this (again) is the Red Heart Knit Fanfare Bucket Hat from Yarnspirations. This cute striped hat can be worked in team colors, and while I might prefer a non-acrylic yarn for a summer hat, it would be fine when it’s not too hot outside (or try a cotton yarn instead). 

Claire Slade’s Sunlit Bucket Hat has an angled brim to help keep the sun out of your eyes. It’s worked from the bottom up using worsted weight cotton yarn, and comes in three sizes. You can find the pattern on Ravelry. 

Get a little air flow in your bucket hat with the Shady Bucket Hat from Wool & Beyond. This one uses DK weight yarn and an eyelet pattern throughout the body to keep it cool. It comes in sizes ranging from newborn to adult large, and is worked in one piece from the top down. You can grab the pattern (in English or Swedish) on Ravelry. 

If you’re looking for a fun, floppy sun hat for kids or adults, this pattern from Muki Crafts is a little more slouchy than a traditional bucket hat but it’s super cute. It comes in baby, toddler and bigger kid sizes and adult. I uses worsted weight yarn and is worked from the bottom up. 

Another variation on the classic bucket is this one that’s more of a cloche style. Made by branda, it uses bulky yarn so it’s more of a winter bucket hat, but now’s a fine time to knit it if you live somewhere that’s warm right now (or even more so if you live somewhere that’s cold right now). 

Another one to get you ready for colder weather is Tirmety, a two-layer bucket hat from ViTalina Craft, which has a textured stitch pattern on one side and stockinette on the other. You can wear either side out or even make them different colors if you want. The pattern is sized for toddlers, kids and adults. 

And if you want to add some extra cuteness to your bucket hat, I love this (of course totally optional but also totally adorable) embroidered deatila on the New York Bucket Hat from Pauline Fanguin. It uses two strands of DK weight yarn held together for extra sturdiness, and uses changes in needle size to shape the hat. Of course you could also knit stripes or use different textures of yarn to change up the look. This pattern is made to fit your head and is available in French and English.
