The correct answer is 'Smooth fibre and Moderate elongation'.

Key Points

• Physical Properties of Silk:
  • Smooth Fibre: Silk is known for its smooth and soft texture, which gives it a luxurious feel. This property makes it highly desirable for clothing and textiles.
  • Moderate Elongation: Silk fibres can stretch moderately without breaking, providing a balance of flexibility and strength. This makes silk durable and able to withstand some degree of tension.

Additional Information

• High Density:
  • Silk does not have a high density. In fact, it is relatively lightweight, making it comfortable to wear and suitable for various applications.
• Low Moisture Regain:
  • Silk has a high moisture regain, meaning it can absorb moisture well. This property contributes to its comfort in different climates.

The correct answer is 'Loft'

Key Points

• Loft:
  • Loft refers to the ability of a fibre to maintain its thickness, volume, and resilience over time.
  • This characteristic is especially important in applications such as insulation, bedding, and upholstery, where maintaining volume and providing cushioning is crucial.
  • Fabrics with good loft are able to trap air, providing better insulation and comfort.

Additional Information

• Elasticity:
  • Elasticity refers to the ability of a fibre to return to its original shape after being stretched or compressed.
• Wickability:
  • Wickability is the ability of a fibre to draw moisture away from the body and disperse it across the surface for evaporation.
• Resilience:
  • Resilience is the ability of a fibre to recover from deformation, such as bending, compressing, or stretching.

The correct answer is 'Iodine'

Key Points

• Starch Paste for Iodine Stains:
  • Starch paste is effective in removing iodine stains because iodine reacts with starch to form a blue-black complex, which can then be washed away.
  • This reaction helps in lifting the iodine stain from the fabric or surface, making it easier to clean.

Additional Information

• Ink Stains:
  • Ink stains are usually removed using alcohol-based solutions or specialized ink removers, not starch paste.
  • These solutions break down the ink pigments, making it easier to wash them off.
• Rust Stains:
  • Rust stains are typically treated with acidic solutions like lemon juice or vinegar, which react with the rust (iron oxide) to dissolve it.
  • Starch paste does not have the chemical properties needed to remove rust stains effectively.
• Grass Stains:
  • Grass stains are usually removed using enzyme-based detergents, which break down the proteins and pigments in the stain.
  • Starch paste does not contain enzymes and is therefore ineffective in treating grass stains.

The correct option is '1)D, C, E, B, A, F'.

Key Points

• Designing (D) is the first step in the carpet making process.
  • This involves creating the pattern or design that will be followed throughout the carpet making process.
• Writing talim (C) follows designing.
  • The design is translated into a coded language called 'talim', which guides the weavers on knotting patterns, color use, and design replication.
• Knotting (E) is the next crucial step.
  • This is where the actual carpet is made by knotting yarns as per the talim instructions.
• After knotting, cutting of pile (B) is done.
  • This process involves trimming the yarns to ensure a uniform surface and texture.
• Washing (A) the carpet comes next.
  • After cutting, the carpet is washed to remove any dirt and to ensure the colors are set properly.
• Drying (F) is the final step in the carpet making process.
  • The carpet is left to dry completely before it can be used or sold.

Hence, the correct sequence of carpet making is D, C, E, B, A, F.

Vicuña is a natural protein fibre.

Key Points

• Vicuña:
  • Vicuña fiber comes from the Vicuña, a camelid species native to South America, closely related to the llama.
  • This fiber is known for its exceptional softness, warmth, and rarity. It is considered one of the most luxurious and expensive natural fibers in the world.
  • Vicuña fiber is a protein fiber, similar to wool, obtained from the coat of the Vicuña. It is highly prized for its fine quality and is often used in high-end fashion.

Additional Information

• Sisal:
  • Sisal is a natural fiber derived from the Agave sisalana plant, primarily used for rope, twine, and other durable materials. It is not a protein fiber but rather a cellulose-based fiber.
• Aramid:
  • Aramid fibers are synthetic, high-performance fibers used in various applications, including bulletproof vests and firefighting equipment. They are known for their strength and resistance to heat and are not natural protein fibers.
• Anidex:
  • Anidex is a type of synthetic fiber and not a natural protein fiber. It is used in the textile industry for specific applications, offering different properties compared to natural fibers.

The correct answer is Pile Weave.

Key Points

• Pile Weave:
  • Pile weave is a weaving technique used to create a three-dimensional fabric by incorporating extra warp or filling yarns.
  • These additional yarns are woven into the base fabric to form loops or cut ends, creating a pile on the surface of the fabric, which can be either cut or uncut.
  • This technique is commonly used in the production of carpets, velvets, and other plush textiles.

Additional Information

• Leno Weave:
  • Leno weave uses a special technique in which pairs of warp yarns are twisted around each other and then woven with a weft yarn. This creates a stable and open fabric that is less likely to fray or unravel.
  • It is often used in the production of sheer fabrics, such as marquisette and mosquito netting.
• Twill Weave:
  • Twill weave is characterized by diagonal ribs on the fabric surface. It is achieved by passing the weft thread over one or more warp threads and then under two or more warp threads.
  • Common examples include denim, tweed, and gabardine.
• Dobby Weave:
  • Dobby weave is a type of patterned weave that uses a dobby attachment on the loom to raise and lower the warp threads individually, allowing for the creation of small, geometric patterns.
  • It is used in a variety of fabrics, including some types of shirting and decorative fabrics.

The correct answer is 'Felting'

Key Points

• Felting:
  • Felting is the process of matting wool fibers together using heat, steam, and pressure to form a dense and durable fabric.
  • This technique has been used for centuries to create various items, including clothing, hats, and artistic pieces.
  • Felting can be done using both wet and dry methods. Wet felting uses water and soap, while dry felting uses a needle.
  • The fibers' scales interlock during the process, creating a firm, non-woven fabric.

Additional Information

• Knotting:
  • Knotting involves tying threads or yarns into knots to create patterns or secure materials. It is not used to create fabric from wool fibers.
  • Common applications include macramé and fishing nets.
• Knitting:
  • Knitting is a method of creating fabric by interlocking loops of yarn with needles. It results in a stretchy and flexible fabric.
  • This technique is commonly used for making garments such as sweaters, scarves, and socks.
• Braiding:
  • Braiding involves intertwining three or more strands of yarn or fabric to create a braid. It is often used for decorative or functional purposes.
  • Common uses include hairstyles, ropes, and trimmings.

The correct answer is 'Air jet'.

Key Points

• Air jet:
  • This method of producing textured filament yarns does not require the property of thermoplasticity.
  • In the air jet texturing process, high-speed jets of air are used to create loops and entangle the filaments, imparting texture to the yarn.
  • This method can be used with various types of fibers, including those that are not thermoplastic.

Additional Information

• False twist:
  • This method involves twisting the yarn, heating it to set the twist, and then cooling it. The property of thermoplasticity is essential here as it allows the yarn to retain the twist.
• Crimp gear up:
  • This method uses gears to create crimps in the yarn. Thermoplasticity is important as it helps in setting the crimp pattern when the yarn is heated and then cooled.
• Knife edge:
  • This technique involves running the yarn over a sharp edge to create curls or crimps. The yarn needs to be thermoplastic to hold these deformations permanently after heating and cooling.

The correct answer is 'In warp knitting, the yarns interlace both vertically and horizontally.'

Key Points

• Warp knitting:
  • Warp knitting is a fabric production technique where yarns run vertically in the fabric, and the loops are interlaced in a zig-zag pattern along the length of the fabric.
  • This method allows the yarns to interlace both vertically and horizontally, providing unique structural characteristics to the fabric.
  • Warp knitting machines use multiple yarns simultaneously, which are guided by needles to create the fabric structure.
