Bonded leather, also called reconstituted leather, composition leather [1] [2] or blended leather, is a term used for a manufactured upholstery material which contains animal hide. It is made as a layered structure of a fiber or paper backer covered with a layer of shredded leather fibers mixed with natural rubber or a polyurethane binder that is embossed with a leather-like texture.
It differs from bicast leather, which is made from solid leather pieces, usually from the split, which are given an artificial coating.
Bonded leather is made by shredding leather scraps and leather fiber, then mixing it with bonding materials. The mixture is next extruded onto a cloth or paper backing, and the surface is usually embossed with a leather-like texture or grain. Color and patterning, if any, are a surface treatment that does not penetrate like a dyeing process would. The natural leather fiber content of bonded leather varies. The manufacturing process is somewhat similar to the production of paper. [3]
Lower-quality materials may suffer flaking of the surface material in as little as a few years, while better varieties are considered very durable and retain their pattern and color even during commercial use. [3] Because the composition of bonded leathers and related products varies considerably, and is sometimes a trade secret, it may be difficult to predict how a given product will perform over the course of time. There is a wide range in the longevity of bonded leathers and related products; some better-quality bonded leathers are claimed to be superior in durability over low-quality genuine leather. [4]
Bonded leather can be found in furniture, bookbinding, and various fashion accessories. Products that are commonly constructed with different varieties of bonded leather include book covers, cases and covers for personal electronics, shoe components, textile and accessory linings, portfolios and briefcases, handbags, belts, chairs, and sofas. [5] A more fragile paper-backed bonded leather is typically used to cover books such as diaries and Bibles, and various types of desk accessories. These bonded leathers might contain a smaller proportion of leather than those used in the furniture industry, and have some leather exposed in the product's surface, producing the characteristic odor associated with leather.
These same applications can alternately use artificial leather constructed in a similar appearance to bonded leather.
Possible advantages of bonded leather include:
Possible drawbacks include: [3] [7]
The actual leather content of bonded leather varies depending on the manufacturer and the quality level.
There is some debate and controversy over the ethics of using the term "bonded leather" to describe an upholstery product, which is actually a reconstituted leather, specifically in the home furnishings industry. A Leather Research Laboratory commented calling a product "bonded leather" is "deceptive because it does not represent its true nature. It's a vinyl, or a polyurethane laminate or a composite, but it's not leather". [12]
In 2011 the European Committee for Standardization published EN 15987:2011 'Leather - Terminology - Key definitions for the leather trade' to stop confusion about bonded leather, according to which the minimum amount of 50% in weight of dry leather is needed to use the term "bonded leather".
The US Federal Trade Commission recommends giving a percentage of leather included. [13] The Federal Trade Commission has said that "The guidelines caution against misrepresentations about the leather content in products containing ground, reconstituted, or bonded leather, and state that such products, when they appear to be made of leather, should be accompanied by a disclosure as to the percentage of leather or other fiber content. The guidelines also state that these disclosures should be included in any product advertising that might otherwise mislead consumers as to the composition of the product." [14] [15]
Leather is a strong, flexible and durable material obtained from the tanning, or chemical treatment, of animal skins and hides to prevent decay. The most common leathers come from cattle, sheep, goats, equine animals, buffalo, pigs and hogs, and aquatic animals such as seals and alligators.
Suede is a type of leather with a fuzzy, napped finish, commonly used for jackets, shoes, fabrics, purses, furniture, and other items. The term comes from the French gants de Suède, which literally means "gloves from Sweden". The term was first used by The Oxford English Dictionary in 1884.
A cushion is a soft bag of some ornamental material, usually stuffed with wool, hair, feathers, polyester staple fiber, non-woven material, cotton, or even paper torn into fragments. It may be used for sitting or kneeling upon, or to soften the hardness or angularity of a chair or couch. Decorative cushions often have a patterned cover material, and are used as decoration for furniture.
Pulpwood can be defined as timber that is ground and processed into a fibrous pulp. This type of wood is commonly used for paper-making but can also be made into low-grade wood and used for chips, energy, pellets, and engineered products.
Microfiber is synthetic fiber finer than one denier or decitex/thread, having a diameter of less than ten micrometers.
Upholstery is the work of providing furniture, especially seats, with padding, springs, webbing, and fabric or leather covers. The word also refers to the materials used to upholster something.
A mattress is a large, usually rectangular pad for supporting a lying person. It is designed to be used as a bed, or on a bed frame as part of a bed. Mattresses may consist of a quilted or similarly fastened case, usually of heavy cloth, containing materials such as hair, straw, cotton, foam rubber, or a framework of metal springs. Mattresses may also be filled with air or water.
Consumables are goods that are intended to be consumed. People have, for example, always consumed food and water. Consumables are in contrast to durable goods. Disposable products are a particular, extreme case of consumables, because their end-of-life is reached after a single use.
Artificial leather, also called synthetic leather, is a material intended to substitute for leather in upholstery, clothing, footwear, and other uses where a leather-like finish is desired but the actual material is cost prohibitive or unsuitable, or for ethical concerns. Artificial leather is known under many names, including leatherette, imitation leather, faux leather, vegan leather, PU leather (polyurethane), and pleather.
A countertop, also counter top, counter, benchtop, worktop or kitchen bench, bunker is a raised, firm, flat, and horizontal surface. They are built for work in kitchens or other food preparation areas, bathrooms or lavatories, and workrooms in general. The surface is frequently installed upon and supported by cabinets, positioned at an ergonomic height for the user and the particular task for which it is designed. A countertop may be constructed of various materials with different attributes of functionality, durability and aesthetics, and may have built-in appliances, or accessory items relative to the intended application.
Fiberboard or fibreboard is a type of engineered wood product that is made out of wood fibers. Types of fiberboard include particle board or low-density fiberboard (LDF), medium-density fiberboard (MDF), and hardboard or high-density fiberboard (HDF).
Nonwoven fabric or non-woven fabric is a fabric-like material made from staple fibre (short) and long fibres, bonded together by chemical, mechanical, heat or solvent treatment. The term is used in the textile manufacturing industry to denote fabrics, such as felt, which are neither woven nor knitted. Some non-woven materials lack sufficient strength unless densified or reinforced by a backing. In recent years, non-wovens have become an alternative to polyurethane foam.
Bicast leather is a material made with a split leather backing covered with an embossed layer of polyurethane or vinyl. Bicast leather was originally made for the apparel industry for glossy shoes, and was later adopted by the furniture industry.
Alcantara is the brand name of a synthetic textile with a soft, suede-like microfibre pile, noted for its durability. Alcantara was developed in the 1970s by Miyoshi Okamoto and initially manufactured by the Italian company Alcantara. The term has an Arabic root and means "the bridge".
Clarino (クラリーノ) is a brand name for artificial leather manufactured by Kuraray Co., Ltd. of Japan. It is commonly used in garments, accessories, bags, shoes, furniture, and consumer electronics. Versions are made that simulate suede and top-grain leather.
Ultrasuede is the trade name for a synthetic ultra-microfiber fabric invented in 1970 by Dr. Miyoshi Okamoto, a scientist working for Toray Industries. In Japan, it is sold under the brand name Ecsaine. It is often described as an artificial substitute for suede leather. The fabric is multifunctional: it is used in fashion, interior decorating, automobile and other vehicle upholstery, and industrial applications, such as protective fabric for electronic equipment. It is also a very popular fabric in the manufacture of footbags and juggling balls. Other manufacturers such as Sensuede and Majilite also produce similar product lines of synthetic microfiber suede.
OMNOVA Solutions Inc., is a global manufacturer of laminates, performance films and coated fabrics. OMNOVA was founded in 1999 when GenCorp spun off its Decorative & Building Products and Performance Chemicals businesses into a separate, publicly traded company. OMNOVA's world headquarters is located in Beachwood, Ohio; with additional sales, manufacturing and distribution locations throughout Europe and Asia.
A playground surface is the material that lies under and around swings, slides, monkey bars and other playground equipment. The surfaces are usually made of wood or rubber and designed specifically for aesthetics, child safety, and/or ADA wheelchair accessibility. Playground safety surfacing often involves the use of recycled rubber tire products such as poured rubber, rubber tiles or loose rubber mulch.
Plant-based leather, also known as vegan leather or eco-leather, is a type of material made from plant-based sources as an alternative to traditional leather, which is typically made from animal hides. Plant-based leather can be made from a variety of sources, including pineapple leaves, mushrooms, corn, apple peels, and recycled plastic. The growing interest in sustainable and environmentally friendly products has led to increased demand for plant-based leather in recent years.
Cory says calling these products bonded leather "is deceptive because it does not represent its true nature. It's a vinyl, or a polyurethane laminate or a composite, but it's not leather. If you tar and feather someone, does that make them a chicken?" Obviously not.
