Lint Remover
A lint roller or lint remover is a roll of one-sided adhesive paper on a cardboard or plastic barrel that is mounted on a central spindle, with an attached handle. The device facilitates the removal of lint or other small fibers from most materials such as clothing, upholstery and linen. Once expended, the roll can typically be replaced with a "refill" roll. Invented in 1956 by Nicholas McKay, Sr., his most well-known (and first commercial) product was the Lint Pic-Up, the world's first lint roller. Reusable lint rollers use elastomers, including silicones and polystyrene-ethylene-butylene-styrene as a reusable tacky surface. The material is similar to polymers used in walking toys such as Wacky WallWalker. A lint roller's design enables fast 360 degree rotation, which facilitates the easy removal of unsightly fiber (often animal hair). Lint rollers can be purchased in many sizes, from pet stores, supermarkets and online. The product is popular among dog and cat owners, ...

Silicones
A silicone or polysiloxane is a polymer made up of siloxane (−R2Si−O−SiR2−, where R = organic group). They are typically colorless oils or elastomer, rubber-like substances. Silicones are used in sealants, adhesives, lubricants, medicine, cooking utensils, thermal insulation, and electrical insulation. Some common forms include silicone oil, silicone grease, silicone rubber, silicone resin, and silicone Caulking, caulk. Chemistry More precisely called polymerized siloxanes or polysiloxanes, silicones consist of an inorganic silicon–oxygen backbone chain (⋯−Si−O−Si−O−Si−O−⋯) with two organic groups attached to each silicon center. Commonly, the organic groups are methyl. The materials can be cyclic or polymeric. By varying the −Si−O− chain lengths, side groups, and Cross-link, crosslinking, silicones can be synthesized with a wide variety of properties and compositions. They can vary in consistency from liquid to gel to rubber to hard pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hair
Hair is a protein filament that grows from follicles found in the dermis. Hair is one of the defining characteristics of mammals. The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types, and hair care, but hair is also an important biomaterial primarily composed of protein, notably alpha-keratin. Attitudes towards different forms of hair, such as hairstyles and hair removal, vary widely across different cultures and historical periods, but it is often used to indicate a person's personal beliefs or social position, such as their age, sex, or religion. Overview The word "hair" usually refers to two distinct structures: #the part beneath the skin, called the hair follicle, or, when pulled from the skin, the bulb or root. This organ is located in the dermis and maintains stem cells, which not only re-grow the hair after it falls out, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coat (dog)
The coat of the domestic dog refers to the hair that covers its body. Dogs demonstrate a wide range of coat colors, patterns, textures, and lengths. As with other mammals, a dog's fur has many uses, including thermoregulation and protection from cuts or scratches; furthermore, a dog's coat plays an important role in the showing of purebred dogs. Breed standards often include a detailed description of the nature and attributes of that breed's ideal coat. A dog's coat is composed of two layers: a top coat of stiff guard hairs that help repel water and shield from dirt, and an undercoat of soft down hairs, to serve as insulation. Dogs with both under coat and top coat are said to have a ''double coat''. Dogs with a ''single coat'' have a coat composed solely of guard hairs, with little or no downy undercoat. The terms fur and hair are often used interchangeably when describing a dog's coat, however in general, a double coat, like that of the Newfoundland and most livestock g ...

Supermarket
A supermarket is a self-service Retail#Types of outlets, shop offering a wide variety of food, Drink, beverages and Household goods, household products, organized into sections. This kind of store is larger and has a wider selection than earlier grocery stores, but is smaller and more limited in the range of merchandise than a hypermarket or Big-box store, big-box market. In everyday United States, U.S. usage, however, "grocery store" is synonymous with supermarket, and is not used to refer to other types of stores that sell groceries. The supermarket typically has places for fresh meat, fresh produce, dairy, Delicatessen, deli items, baked goods, etc. Shelf space is also reserved for canned and packaged goods and for various non-food items such as kitchenware, household cleaners, pharmacy products and pet supplies. Some supermarkets also sell other household products that are consumed regularly, such as alcohol (where permitted), medicine, and clothing, and some sell a much w ...

Pet Store
A pet shop or pet store is a retail business which sells animals and pet care resources to the public. A variety of animal supplies and pet accessories are also sold in pet shops. The products sold include: food, treats, toys, collars, leashes, cat litter, cages and aquariums. Some pet stores provide engraving services for pet tags, which have the owner's contact information in case the pet gets lost. In the United Kingdom, United States and Canada, pet shops often offer both hygienic care (such as pet cleaning) and aesthetic services (such as cat and dog grooming). Some pet stores also provide tips on training and behaviour, as well as advice on pet nutrition. Pet stores are extremely popular in modern society. In 2004, according to the American Pet Products Manufacturers Association, in the pet industry, live animal sales reached approximately $1.6 billion. Moreover, in a 2003 survey in the US, merely 38% of U.S. pet shops claimed that they did not sell any live animals. Online ...

Wacky WallWalker
The Wacky WallWalker was a toy molded out of a sticky elastomer. It was shaped similar to a spider, and when thrown against a wall would "walk" its way down. It was a hugely popular toy in the early 1980s. Before its introduction in the United States, Ken Hakuta received in the mail several sticky octopus-like toys from his mother, who lived in Japan. They were intended for his children, but Hakuta found himself fascinated with the toy, which was called ''Tako'' in Japan. He realized their marketing potential, and after purchasing rights to the product in 1983 for $5,000, he began to market them locally in Washington, D.C., dubbing them "''Wacky WallWalkers''". Their popularity was mediocre, until Nina Hyde of ''The Washington Post'' wrote a feature story on them. This created a buzz, and people in the Washington area flooded local stores to purchase them. As the fad began to decline, over 240 million Wacky WallWalkers had been sold, raking in about 80 million dollars. The popular ...

Polymers
A polymer (; Greek '' poly-'', "many" + ''-mer'', "part") is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass, relative to small molecule compounds, produces unique physical properties including toughness, high elasticity, viscoelasticity, and a tendency to form amorphous and semicrystalline structures rather than crystals. The term "polymer" derives from the Greek word πολύς (''polus'', meaning "many, much") and μέρος (''meros'', meani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polystyrene
Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to oxygen and water vapour and has a relatively low melting point. Polystyrene is one of the most widely used plastics, the scale of its production being several million tonnes per year. Polystyrene can be naturally transparent, but can be colored with colorants. Uses include protective packaging (such as packing peanuts and in the jewel cases used for storage of optical discs such as CDs and occasionally DVDs), containers, lids, bottles, trays, tumblers, disposable cutlery, in the making of models, and as an alternative material for phonograph records. As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 °C, its glass transition temperature. I ...

Elastomer
An elastomer is a polymer with viscoelasticity (i.e. both viscosity and elasticity) and with weak intermolecular forces, generally low Young's modulus and high failure strain compared with other materials. The term, a portmanteau of ''elastic polymer'', is often used interchangeably with rubber, although the latter is preferred when referring to vulcanisates. Each of the monomers which link to form the polymer is usually a compound of several elements among carbon, hydrogen, oxygen and silicon. Elastomers are amorphous polymers maintained above their glass transition temperature, so that considerable molecular reconformation is feasible without breaking of covalent bonds. At ambient temperatures, such rubbers are thus relatively compliant ( E ≈ 3 M Pa) and deformable. Their primary uses are for seals, adhesives and molded flexible parts. Application areas for different types of rubber are manifold and cover segments as diverse as tires, soles for shoes, and damping and ...

Adhesive
Adhesive, also known as glue, cement, mucilage, or paste, is any non-metallic substance applied to one or both surfaces of two separate items that binds them together and resists their separation. The use of adhesives offers certain advantages over other binding techniques such as sewing, mechanical fastenings, or welding. These include the ability to bind different materials together, the more efficient distribution of stress across a joint, the cost-effectiveness of an easily mechanized process, and greater flexibility in design. Disadvantages of adhesive use include decreased stability at high temperatures, relative weakness in bonding large objects with a small bonding surface area, and greater difficulty in separating objects during testing. Adhesives are typically organized by the method of adhesion followed by ''reactive'' or ''non-reactive'', a term which refers to whether the adhesive chemically reacts in order to harden. Alternatively, they can be organized eithe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicholas McKay (inventor)
Nicholas McKay, Sr. (December 8, 1920 – November 15, 2014) was an American inventor and entrepreneur. His most well-known (and first commercial) product was the Lint Pic-Up, the world's first lint roller. McKay had the idea after needing masking tape, a paper roll and some wire to clean his suit before chaperoning his son's high school dance in 1956. He and his late wife Helen formed Helmac the next day. Helmac is a household products company that eventually held 92% of the American market in 1996. McKay credits his humble upbringing on a family farm in Ohio during the Great Depression as inspiration of sorts for his career. He produced ''When The World Breaks'', documentaryon parallels between the Great Depression and today's poor economic climate.
