1.
What animal is most commonly used for producing leather?
Correct Answer
A. Cow
Explanation
Cowhide is the most commonly used animal skin for producing leather. This is due to its widespread availability, durability, and the large size of hides it provides, which makes it ideal for a variety of products like furniture, shoes, and jackets. The widespread domestication of cattle for agriculture and dairy products provides a consistent supply, making cowhide a cost-effective choice for leather manufacturers.
2.
Which process stabilizes the leather?
Correct Answer
A. Tanning
Explanation
Tanning is the process that stabilizes the proteins in the raw hide, transforming it into durable and decay-resistant leather. This process involves treating the skins with tannic acid extracted from plant sources or with synthetic agents. The aim is to prevent decomposition and to imbue the leather with desirable properties such as flexibility, water resistance, and a finished appearance that can withstand extensive use.
3.
What type of leather is known for its softness?
Correct Answer
B. Suede
Explanation
Suede is known for its softness, which comes from the process of splitting the hide and sanding or buffing the interior to create a napped, velvety surface. This technique reduces the thickness of the leather and increases its pliability, making suede softer and more flexible than full-grain leather. Suede's distinct soft texture makes it popular for clothing and upholstery, but it is less durable and more prone to getting dirty.
4.
What does 'grain' refer to in leather?
Correct Answer
B. Texture
Explanation
In leather, "grain" refers to the texture and appearance of the surface of the leather, which includes the size and visibility of the pores and any natural marks. Full-grain leather, which includes the outermost layer of the animal's skin, displays the most natural grain, complete with imperfections and the strongest fiber strength. This aspect of leather is important for assessing quality, as finer grains are often more highly valued in luxury products.
5.
Which leather is treated with wax for a shiny finish?
Correct Answer
B. Patent
Explanation
Patent leather is treated with a coating, traditionally linseed oil, though modern methods might use plastic coatings or acrylics, to achieve a glossy, shiny finish. This treatment seals the pores, creating a smooth, reflective surface that is also water-resistant. The process of achieving this high gloss finish involves multiple steps of coating and polishing, which enhances the aesthetic appeal of the leather and protects it.
6.
What is leather from sheep commonly called?
Correct Answer
B. Sheepskin
Explanation
Leather made from sheep is commonly referred to as sheepskin. It includes the fleece of the sheep, which is integral to the leather and provides natural insulation. Sheepskin is renowned for its softness, warmth, and comfort, making it especially popular for clothing and footwear intended for colder climates. The natural lanolin in the wool also makes sheepskin leather self-conditioning.
7.
Which country is leading in leather export?
Correct Answer
C. India
Explanation
India is a leading exporter of leather, thanks to its large livestock population and traditional craftsmanship in leather goods. The country excels in producing a variety of leather products including footwear, garments, and accessories, which are valued internationally for their quality and craftsmanship. This has been supported by government policies aimed at boosting exports through modernization, innovation, and improvements in environmental standards within the industry.
8.
What is the most durable type of leather?
Correct Answer
B. Full-grain
Explanation
Full-grain leather is considered the most durable type of leather because it includes the entire thickness of the hide, which means it retains the tough outer layer of the skin. This layer is the most resistant to wear and tear, moisture, and damage, making it ideal for high-quality furniture, footwear, and goods that are subject to heavy use. Its ability to develop a patina over time also adds to its aesthetic and functional longevity.
9.
Which treatment makes leather water-resistant?
Correct Answer
D. Waterproofing
Explanation
Waterproofing treatments, such as waxing or applying synthetic sealants, make leather water-resistant. These treatments cover the pores in the leather, creating a barrier that prevents water from penetrating the material. This is crucial for leather used in outdoor gear, footwear, and jackets, where protection from moisture is essential. Proper waterproofing not only extends the life of the leather products but also maintains their appearance and usability in adverse conditions.
10.
What is a byproduct of leather that often gets recycled?
Correct Answer
A. Scraps
Explanation
Leather scraps are a byproduct of the cutting and manufacturing process and are often recycled or repurposed to minimize waste. These scraps can be ground up and reconstituted to make bonded leather, used in patchwork, or utilized in smaller leather goods such as wallets, belts, and keychains. This recycling helps in reducing the environmental impact of leather production and promotes sustainability within the industry.
