1) wool rug: the case of a natural protein fiber, soft appearance gloss, elasticity. * Physical properties: strong Hygroscopicity, good elasticity, feel comfortable, not wrinkle, more wear-resistant, but easy to mold-boring. * Chemical properties: not acid-proof alkali, acid will dissolve, more sensitive to oxidants and reducing agents. * Dyeing properties: easy to dye, but also more prone to bleaching. * Method (method) with fire lit a bunch of fibers: burning hair smell and residue free hand twisting into powder after combustion. 2) Acrylic savonnerie rugs (clear polypropylene): the case of chemical fiber, good gloss. * Physical properties: poor moisture, conductivity difference is easy to produce static electricity and contamination phenomena. But have excellent solar performance and excellent mildew resistance ability moth-resistant bacteria. * Chemical properties: on good chemical stability, acid and alkali resistant except in case of strong acid and the temperature is high yellow; also more stable to commonly used reducing agent; not under the influence of organic solvents, oils, surfactants in General. * Dyeing properties: dyed more difficult but not easy to bleaching, and brightly. * Method (method): fire contractile after leaving the flame continues to burn, smoke residue for pine, brittle balls. 3) nylon savonnerie rugs (nylon 66) chemical fiber, feel less * physical properties: elasticity is good (better than wool) toughness high strength abrasion resistant and durable share small resistance to mould boring, poor Hygroscopicity, between between wool and acrylic, poor electrical resistance. * Chemical properties: on the chemical stability of good, but it can be oxidant damage, to General organic solvent-stable, dry cleaner without serious injuries, much more than good alkali resistance of wool, dilute acid does not damage fibers, single concentrated acid will dissolve. * Dyeing performance: identification method for dye decolorization of hardship but not * (combustion): fire contractile, after leaving the flame goes out, burning bright hard beige after the remnants of the ball. 3: constructs the first layer of the savonnerie rugs, surface, usually with natural fibers and synthetic fibers woven into, loose, soft, strong sense of fibers on the surface. Second level, support level: usually fibers woven into, played a supporting role, improve the stability and durability of the savonnerie rugs, yarn and this surface layer wrapped around each other woven materials. Third floor under support layer: general use of hemp or fiber woven into, adhesives bear attachment support, solid bedding combined with whole savonnerie rugs organization: generally plastic hole structure, its role is to make the savonnerie rugs isolated from the ground, with increased permeability and elastic.
