Step 1
Explain how knitted fabric is constructed.
Answer
Knitted fabric is made through a process of interlocking loops, which results in a flexible structure. The construction process can vary depending on whether it is created by hand or machine.
There are two primary knitting methods:
-
Weft knitting: This technique involves running the yarn across the width of the fabric, producing a horizontal layer of intertwining loops. It is commonly executed by hand or machine and is known for its elasticity and comfort.
-
Warp knitting: This method uses a single piece of yarn that zigzags along the length of the fabric. Typically produced by machines, warp knitting creates a more stable and structured fabric compared to weft knitting.
Different looping techniques can also be employed, such as plain, rib, and purl knitting, each giving the fabric unique characteristics.
Step 2
Outline the properties and uses of knitted fabric.
Answer
Properties of knitted fabric include:
- Warmth: Provides insulation, keeping the wearer warm.
- Good elasticity: Able to stretch and return to its original shape, enhancing comfort and fit.
- Lightness: Variable weights depending on the stitch design, allowing for versatile applications.
- Comfortable: Soft and stretchy, making it suitable for clothing.
- Tendency to snag: Can be prone to pulling or snagging, especially at stress points.
- Shrinks: Some knitted fabrics may shrink upon washing.
Uses of knitted fabric include:
- Coats: Offers warmth and flexibility for outerwear.
- Hats: Provides warmth while allowing for stretch and comfort.
- Scarves: Allows for intricate patterns while maintaining softness.
- Dresses: Many styles benefit from the stretch and fit of knitted materials.
- Jumpers: Commonly made with knit fabrics for comfort.
- Throws: Ideal for decorative and functional home textiles.
