Bengaline is a densly woven fabric with ribs at intervals across the fabric. It is made with single warps yarns and heavy filling yarns. It can be made of any and all fibers, as a single fiber or in a blend. The fabric does not wear well. It is best to dry clean. Wet cleaning should be avoided for 2 reasons: shrinkage and the possible presence of soluble sizings, which means water marks could appear. They would be difficult if not impossible to remove.Heavily soiled you might try dry-wet-dry method.
Acrylic is very versatile, can be used for fake furs and blankets. Looks and feels like wool more then any other fiber.Soft hand,resilience, resistance to shrinkage, and good bulking capabilities make oit good for these uses. It blends well with wool and other fabrics. Can be solution dyed. Weaknesses it is heat sensitivity and pilling. Acrylic is oleophillic meaning it love oil. So it tends to retain oil stains. Prefer wet cleaning clean well and dry fast sense they are hydrophobic water heating.
We will focus on upholstery cleaning for a while these are guidelines only pre test and follow all directions on specific products. Acetate is a low cost fiber found alone or in blends in some upholstery and slip covers. Fabrics made from acetate are supple and drape well. They are resistant to mold, mildew, and moths. Acetate can be solution dyed resulting in excellent colorfastness. Blends can bleed or shrink.
Acetate fabrics due have limitations. They have low elasticity and do not resist wrinkling They are low in strength and lose strength when wet. They get weaker with direct sun. Weakened by strong alkalizes and strong acids. It dissolves in acetone, which is nail polish remover. Can be dry cleaned or wet cleaned.
Acetate fabrics generally don't shrink. Weak solutions off sodium hypochlorite and hydrogen peroxide can be used. Go to a UFT class to learn more.
