Basic of Knitting | Warp and Weft Knitting Mechanism || How Knit Fabric Produces ?

Summary

Knitting involves intermeshing yarn into loops to form fabric. There are two main knitting systems: weft and warp knitting. Weft knitting forms horizontal loops using either circular or flatbed machines. The horizontal loops, called courses, are created by adjacent needles working in sequence. In contrast, warp knitting forms vertical loops, with each needle knitting its own lengthwise yarn simultaneously. Warp knitting machines require yarns to be arranged parallel and are commonly used for more intricate fabrics like tricot and crochet. This overview highlights the basic differences between weft and warp knitting methods.

Takeaways

• 🧶 Knitting is the process of intermeshing yarn into loops to create fabric.
• 🧵 There are two primary knitting systems: weft knitting and warp knitting.
• 🪡 Weft knitting creates fabric with loops arranged horizontally by adjacent needles.
• 🔄 Circular knitting machines are commonly used for weft knitting, creating tubular fabrics.
• 📐 The width of the fabric in circular knitting is determined by the number of needles on the machine.
• 🧍 Flatbed machines can also perform weft knitting on flat needle beds.
• ↔️ In weft knitting, horizontal rows of loops produced by adjacent needles are called courses.
• ⬇️ Vertical columns of loops created by the same needle over successive knitting cycles are called wales.
• 🔗 Warp knitting differs by forming loops vertically and using separate lengthwise yarns for each needle.
• 🧵 Warp knitting requires parallel yarns, and each needle usually has its own warp yarn for basic fabrics.

Q & A

What is knitting, according to the script?

Knitting is defined as the intermeshing of yarn into loops to form fabric.

What are the two main systems of knitting mentioned in the script?

The two main systems of knitting are weft knitting and warp knitting.

How does weft knitting differ from warp knitting in terms of loop formation?

In weft knitting, loops are formed in a horizontal manner by adjacent needles, whereas in warp knitting, loops are formed vertically, intermeshing with two adjacent vertical columns known as 'wales.'

What is a common machine used for weft knitting, and what does it produce?

A common machine used for weft knitting is the circular knitting machine, which produces a tube of fabric in a spiral configuration.

What determines the width of the fabric in weft knitting using a circular machine?

The width of the fabric is determined by the number of needles on the circular knitting machine.

What is a 'course' in knitting, and how is it measured?

A course is the horizontal row of loops produced by adjacent needles during the same knitting cycle. It is measured by the number of courses per linear unit, such as inches or centimeters.

What is a 'wale,' and how is it counted?

A wale is the vertical column of loops produced by the same needle during successive knitting cycles. The wale count is measured by the number of wales per linear length, such as inches.

How is fabric formed in warp knitting machines?

In warp knitting machines, individual loops are created from separate lengthwise yarns that are fed vertically, with needles knitting the warp yarns simultaneously across the width of the machine.

What is required in warp knitting if 1,000 needles are used?

If 1,000 needles are used in warp knitting, a minimum of 1,000 warp yarns are required, one for each needle.

What types of fabrics are typically produced using warp knitting machines?

Warp knitting machines are typically used to produce fabrics like tricot and crochet fabrics.
