Test on Sewing Technology and Production Systems

Question 1: Is a spool characteristically shaped like a cone among the various thread packages?

A. Ano

B. Ne

Explanation: The study materials illustrate a spool as having a cylindrical shape, while a cone is shown with a distinct conical form.

Question 2: According to the study materials, what characteristics describe ply and cord threads, which are mentioned under the 'MAKING COTTON AND POLYESTER THREAD' section?

A. They are made from continuous filaments of polyester or nylon.

B. They have a high degree of resistance to abrasion.

C. They have a high level of twist, making them bulky.

D. They are typically used in heavy-duty applications like furniture and shoes.

Explanation: The study materials state that 'Ply and cord Threads - are made from continuous filaments of polyester or nylon that have been bonded together.' They 'look like a single cord of yarn' due to very little twist. They 'provide a low-seam profile and therefore a high degree of resistance to abrasion and are used in the manufacturing of furniture, shoes, and other heavy duty applications.' This confirms options 0, 1, and 3. Option 2 is incorrect because the material states they 'have very little twist'.

Question 3: Lapped seams are primarily used for applications such as shirts and blouses, and their structure involves placing two fabric edges one over another before stitching.

A. Ano

B. Ne

Explanation: The study materials state that the structure of a lapped seam involves one fabric edge overlapping another and being stitched through both layers. This is contrary to placing two fabric edges one over another, which describes a superimposed seam. Furthermore, applications for superimposed seams include shirts and blouses, while lapped seams are typically found in jeans, uniforms, and sportswear.

Question 4: According to the provided study materials, which of the following are listed as applications for a Superimposed Seam (Class 1)?

A. Attaching patch pockets

B. Side seams of skirts

C. Finishing belt ends

D. Side seams of dress skirts and jeans

Explanation: The study materials state that Superimposed Seam (SSa) is used for 'Side seam of skirt, dress slacks, inseam or side seam of jeans' and (SSb) for 'Finishing belt ends; attaching elastic to waistband'. Attaching patch pockets (LSd) and Side seams of dress skirts and jeans (LSc) are applications for Lapped Seams (Class 2), not Superimposed Seams.

Question 5: An overlock seam is an example of an Edge Finishing Seam.

A. Ano

B. Ne

Explanation: The study materials list 'Overlock seam' under the examples for the Edge Finishing Seam (Class 5).
