But because the feather is to rely on to keep warm, so using medium pressure in the body part of the heat preservation is not very ideal, when used with high-grade dampproof mat.
Fine cotton sleeping bag because cotton is different, so warm index difference is very big.
< / p > < p > at present, the market of fine cotton sleeping bag filling material with spray adhesive cotton, imitation silk floss, dupont cotton, cotton, oprah card containing silicon 3 d cotton, etc.
300 g/m2 filling, for example, spray adhesive cotton thermal indicators, the target temperature in 5 degrees or so, imitation silk floss in -

When processing, the material and a layer of filling material stitched together, fabrics and also a layer of filling material stitched together.
Then put two layers of the sutures of stagger added together.
Sleeping bag has good warmth retention property of this process, there will be no needle drafty.
< / p > < p > imbricate type is one of the most complex treatment, at the time of processing, after, filling material is cut into small pieces, small pieces of material stitched together in one end and the other end and fabric stitch together.
This technology has a better effect of warm, breathable and intensity, Labour cost is higher than double type many, multi-purpose on some high-grade sleeping bag.
