Textiles

Step 1: Understanding the Concept:
This is a direct question about the origin of a specific type of fabric. Fabrics are named after the fibers from which they are made.

Step 2: Detailed Explanation:
- Cotton cloth is, by definition, a textile woven from the fibers harvested from the boll of the cotton plant.
- Linen is a fabric made from the fibers of the flax plant. - Kapok fibers come from the kapok tree and are typically used as stuffing, not for weaving cloth. - Jute is a coarse fiber from the jute plant, used to make burlap sacks and ropes. Therefore, cotton cloth is made from cotton fibers.

Step 3: Final Answer:
The fiber used to make cotton cloth is cotton.

Step 1: Understanding the Concept:
The process of "washing clothes" or doing laundry involves a series of steps to clean and prepare garments for wearing again. The question asks to identify the activity that is not part of this cleaning process.

Step 2: Detailed Explanation:
The typical laundry process includes:

Sorting clothes.
Pre-treatment, such as stain removal.
The main washing cycle (using water and detergent).
Rinsing to remove soap.
Drying the clothes (by hanging or using a machine).
Ironing/Folding.
Storage (placing clothes in a closet or drawer) is the action taken after the entire washing and preparation process is complete. It is not part of the cleaning process itself.

Step 3: Final Answer:
Stain removal, washing, and drying are all integral parts of the laundry process. Storage is what is done with the clothes after they have been washed.

Step 1: Understanding the Concept:
Absorbency in textiles refers to a fabric's ability to take in and hold moisture. This property is crucial for comfort, especially in clothing worn next to the skin. Different fibers have different levels of absorbency based on their chemical and physical structure.

Step 2: Detailed Explanation:
- Cotton: Cotton is a natural cellulosic fiber. Its structure contains many hollow spaces (lumens), which makes it highly absorbent. It can absorb a significant amount of water, making it comfortable to wear in warm climates as it absorbs sweat.
- Woollen: Wool is a natural protein fiber that can also absorb moisture, but it is primarily known for its insulating properties.
- Silk: Silk is another natural protein fiber with moderate absorbency.
- Polyester: Polyester is a synthetic polymer. It is hydrophobic, meaning it repels water rather than absorbs it. Its low absorbency is why it is known for its moisture-wicking properties and quick-drying capabilities, often used in activewear.
Among the given options, cotton is most distinguished by its high absorbency.

Step 3: Final Answer:
Cotton is the textile best known for its special property of high absorbency.

Step 1: Understanding the Concept:
The question asks to identify the natural fiber that is sourced from the protective casing spun by an insect larva.

Step 2: Detailed Explanation:
- Silk is a natural protein fiber produced by the larva of certain insects, most notably the mulberry silkworm (Bombyx mori), to form a cocoon. The cocoon is then harvested and processed to extract the silk fiber.
- Wool is a fiber obtained from the fleece of sheep and other animals.
- Linen is a plant fiber obtained from the flax plant.
- Cotton is a plant fiber obtained from the bolls of the cotton plant.

Step 3: Final Answer:
Silk is the fiber obtained from the cocoon of a silkworm.
