This is the most common way of treating non-washable fabrics. The front of the fabric is sponged with a sponge that is soaked in the solvent being used. The rear of the fabric should be backed up with a clean, absorbent, material. The stain is rubbed with the sponge radially, from the centre of the stain towards its edge.
Damage can occur when ceramics are exposed to freezing temperatures and frost. The problem occurs when ice crystals form inside of the pores of the ceramic piece. The frost inside of the pores will exert pressure onto the fabric of the pottery and cause the material to crack and break. [4]: p.24
Elastolefin is a fiber used in fabrics. [16] IKEA's Better Shelter uses structural panels made out of polyolefin foam, stating, "They are tough and durable.". [17] Piping systems for the conveyance of water, chemicals or gases are commonly produced in Polypropylene, and to a much greater extent Polyethylene. Piping systems in high-density ...
Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone (>C=O).It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.
Polypropylene, highly colorfast, is widely used in manufacturing carpets, rugs and mats to be used at home. [47] Polypropylene is widely used in ropes, distinctive because they are light enough to float in water. [48] For equal mass and construction, polypropylene rope is similar in strength to polyester rope.
Applying cyanoacrylate to some natural materials such as cotton (jeans, cotton swabs, cotton balls, and certain yarns or fabrics), leather or wool results in a powerful, rapid, exothermic reaction. This reaction also occurs with fiberglass and carbon fiber. The heat released may cause serious burns [34] or release irritating white smoke.
The heat-sensitivity of modacrylic also allows wigs and hairpieces to be curled and heat styled without damage. [3] Modacrylics are also used in fleece, knit-pile fabric backings, and nonwoven fabrics. Other uses of modacrylics include paint rollers, industrial fabrics, stuffed toys and filters. [5]
However, while plastic deformation essentially occurs at constant volume, crazing is a cavitation process that takes place with an increase in volume. The initiation of crazing normally requires the presence of a dilative component of the stress tensor and can be inhibited by applying hydrostatic pressure.
