Question

Maximum machine diameter for circular weft knit machine is

• A. 50 inches
• B. 30 inches
• C. 60 inches
• D. 10 inches

Hint:

• Circular weft knitting machine diameters vary widely depending on the end product.
• Common diameters for apparel fabrics (body-size) are in the range of 24-34 inches.
• Larger diameter machines (e.g., 38 inches and above, up to 50 or 60 inches or more) are used for wide fabrics or specific applications like mattress ticking.
• The term "maximum" can be ambiguous. If 30 inches is correct, it might refer to a common upper limit for a standard category of machines.

Answer 1

The Correct Option is B

In the context of textile engineering, particularly when discussing circular weft knit machines, the diameter of the machine plays a critical role in determining the scale of production and the type of fabrics produced. Circular weft knit machines are used to produce tubular fabrics and are a predominant choice in the textile industry for making knit fabrics due to their efficiency and versatility.

The maximum machine diameter refers to the largest size in inches that these machines can be manufactured for practical production purposes. The diameter affects the production rate, with larger diameters capable of producing more fabric in a given time.

In this scenario, the options available for the machine diameter are:

50 inches

30 inches

60 inches

10 inches

The most common and practical maximum diameter for circular weft knit machines in the industry is 30 inches. This size balances machine cost, floor space, and production demands. Larger diameters like 50 inches or 60 inches are less common due to their increased complexity, cost, and the specialized needs they serve.

Therefore, from the given options, the correct maximum machine diameter for a circular weft knit machine is 30 inches.
