Test on Knitted Technology and Textile Machinery

Question 1: In weft knitting technology, the subsequent loops formed from a single thread are typically placed in subsequent courses.

A. Ano

B. Ne

Explanation: The study materials state that in knitted technology, the subsequent loops formed from one thread are placed in the same course for weft knitting. The placement of subsequent loops from one thread in subsequent courses is characteristic of warp knitting.

Question 2: The production of dial and cylinder weft knitted spacer fabrics can be achieved using only two distinct types of yarn.

A. Ano

B. Ne

Explanation: All techniques for producing knitted spacer fabrics using dial and cylinder needles require at least three different yarns: one for the cylinder needles, one for the dial needles, and a dedicated spacer yarn, typically a monofilament yarn, for connecting the two layers.

Question 3: In the context of seamless knitting technology, which of the following characteristics is attributed to warp knitting when compared to weft knitting, according to the provided study materials?

A. The capability for unlimited patterning using Jacquard throughout the entire product.

B. The benefit of simultaneously knitting complete garment sections, including sleeves and body.

C. A reduced tendency towards the formation of laddering.

D. The ease of changing patterns, making it suitable for small batch production of various product sizes.

Explanation: The study materials indicate that seamless warp knitting has a '+ Less disposition to the laddering', distinguishing it from weft knitting, which is noted to have '- Laddering'. The other options describe characteristics associated with weft seamless knitting, specifically '+ Simultaneously knitting pieces (sleeve – body (torso) – sleeve)', '+ Jacquard – unlimited patterning in whole product', and '+ Easily changing of the pattern, small batch production of various size product'.

Question 4: According to Cass (2000), what are the primary structural components of a three-dimensionally knit spacer fabric?

A. A top layer

B. A middle connecting layer

C. A bottom layer

D. An outer decorative layer

Explanation: The study materials state that spacer fabrics feature "two complementary slabs of fabric with a third layer tucked in between." This is further illustrated by the diagram showing "Top Layer," "Connecting Layer," and "Bottom Layer." An outer decorative layer is not identified as a primary structural component.

Question 5: Seamless warp-knitted articles are normally finished individually during the relaxing and heat-setting process.

A. Ano

B. Ne

Explanation: When relaxing and heat-setting conventional seamless articles, the tubes and stockings are normally finished individually.
