advantages and disadvantages of elasticity in yarns?

Advantages of elasticity in yarns:

1. Stretchability: Elastic yarns can stretch and recover their original shape, making them ideal for stretchy and form-fitting garments.

2. Comfort: Elastic yarns provide a comfortable and flexible fit, allowing for ease of movement and comfort during wear.

3. Durability: Elastic yarns are often more durable and resistant to wear and tear compared to non-elastic yarns, making them suitable for long-lasting garments.

4. Versatility: Elastic yarns can be used in a variety of applications, including sportswear, activewear, lingerie, and hosiery.

Disadvantages of elasticity in yarns:

1. Limited stretch: Some elastic yarns may have limited stretch capabilities, which can restrict movement and comfort.

2. Potential for sagging: Over time, elastic yarns may lose their elasticity and sag, leading to a less flattering fit.

3. Cost: Elastic yarns can be more expensive than non-elastic yarns, which can increase the cost of production for garments.

4. Maintenance: Elastic yarns may require special care during washing and drying to maintain their elasticity and shape.
