Designing a lunch bag with wool felt is in progress. I’m thinking to put a bag-in-bag using cotton or linen cloth to protect the wool felt from a dirt even though wool is water-repellent to some extent, because wool felt is not machine washable.
Then I did a quality test on how much wool’s water-repellent nature is effective against stain. My conclusion was, “Bag-in-bag is still needed for a lunch bag, but stain on wool felt could be removed when it’s still wet”. I asked if I could keep on going with this result on this blog, and some of my readers said, “NO” on my Facebook page ;).
“It doesn’t make sense if a bag-in-bag let a dirt go through.”
“You may not always able to clean a stain off from wool felt before it dries.”
…Yes, that’s right. Then what can I do?
…I got three ideas.
1. using water-repellent cloth (e.g. nylon, vinyl)
2. applying a water-proofing treatment (e.g. waterproofing splay)
3. applying a laminate sheet
First of all, I looked for water-repellent cloths at a local shop, and found following three kinds of cloth.
A. a cover sheet that protects a car from rain and UV
B. a bedding sheet for infants preventing from bed-wetting. One side is coated with rubber-like material.
C. cloth for a diaper cover laminated on a jersey material
Colors or stretching properties of the cloths don’t seem to go well with my lunch bag, but I did a quality test again using soy sauce and ketchup to find out which cloth could work.
First, A. a cover sheet that protects a car from rain and UV. It’s made of nylon.
Next is B. a bedding sheet for infants preventing from bed-wetting. One side is coated with rubber-like material.
Finally, C. cloth for a diaper cover laminated on a jersey material
Here came the results.
Afterward, I took contact with cloth processing companies offering water proofing treatment, and found these facts:
– Water proofing treatment will loose its effect after washing the cloth
– Water proofing treatment does not prevent a dirt from getting through the cloth (like my test “A” above.)
Water proofing treatment does not work so that the only possible way is LAMINATING.
I think the textile design of the bag-in-bag is very important, so I don’t want to choose just another laminated table cloth or something like that. But I suppose ordering laminating process on original fabric will demand me a large order….
And now, I found laminating sheet for fabric, Iron-On Vinyl! It’s durable, flexible and sew-able… I’ve already got it from the USA!
To be continued. Stay tuned :)
