In describing woven fabric, the term end or number of ends refers to
warp yarn
A woven fabric is labeled having a fabric count of 100x50. This means that the fabric has __________ yarns per square inch
5,000
The number of needles per inch on a knitting machine is termed as
Gauge
Pilling is an indicator of fabric quality. The pilling test ranks the fabric by a 1 to 5 scale. Scale 1 rating means no visible pilling while 5 means extreme pilling
True
Which of the following fabrics will have highest pilling tendency?
-100% flat polyester filament
-Elastic core compound yarn with textured
filament cover
-100% woolen yarn
-100% worsted
Which of the following fabric has the highest propensity to run and lose shape, but it’s easy to stretch and thus more comfortable to wear.
Single weft Jersey knit
Among the following fabrication methods which one can be the fastest one to produce thus the cheapest
Compound such as laminated
Which of the following fiber has the largest nonwoven fabric share due to its low price yet with suitable properties such as zero moisture regain and lowest density, no chemical reactivity?
Olefin such as polypropylene
In textile industry, tentering is a process of
Stretching and steaming fabric with
designed width and correct grain direction
and fabric count
Desizing means
Taking out the starch solution added to
warp yarns before weaving for the purpose of
reducing yarn break
Mercerization is a finishing applied to
Cotton fabric – to make it lustrous and
stronger
Overall calendaring finishing process makes the fabric more lustrous. This is due to the fact that
-small nano particles are pressed into the
fabric by heated roller
-the yarns in the fabric are flattened by
heated roller to reflect light better
-the fussy fiber ends are removed by flame-the fiber morphology is changed due to the
pressure from heated roller
Nano technology is the new frontier of science and technology application. It has been used in textile industry to improve fabric performance. Which of the following is around the nano scale
Nanotechnology, when applied to textiles, can make the textiles
resistant to water, stain and soiling
resistant to bacteria and inhibit odor
resistant to wrinkling and UV light
resistant to static build up
Color is a physical property of a substrate, such as a fabric, its color is perceived the same no matter by whom and by what kind of light
False
Which part of the human eyes is responsible for seeing color
Cones
When we perceive dark color from a substrate, it means that all wavelengths of the electromagnetic waves in the visible range are reflected by the substrate
False
When you choose lightings for visual merchandising, what is the Color Rendering Index for good lighting quality that you should consider?
above 80
When color transfer from one fabric to another due to rubbing or abrasion, this is termed as
Crocking (dry or wet)
Level indicates which color quality of a fabric
The uniformity of solid color through the
fabric
Among carpets of different fibers, which fiber is most stain resistance and chemically inert, thus can be cleaned by bleach. However, this fiber is most oleophilic and can be crushed easily due to its lower resilience
Polypropylene (olefin)
Polyester fiber is also oleophilic because of its very low moisture regain at 0.5%.
True
Which of the following fibers is used for making commercial carpet due to its high performance in resilience and abrasion resistance
Nylon 6 and Nylon 6.6
Coloration method, such as if the fiber is solution dyed or not, does not affect its product stain resistance because it is for design or aesthetic concern
True
Fiber size and morphology affect comfort such as sensorial (soft or rough) and they don’t affect a product’s maintenance performance such as soiling propensity
False
What are the five possible textile components and what are the seven textile serviceabilities?
Textile Components: Fibers, yarns, fabrication, coloration, finishing
Serviceabilities: durability, comfort & safety, cost, aesthetic, care & maintenance, environmental impact, appearance retention
What is the relationship between the components and the serviceabilities?
the performance quality of a textile relies on that of the development and production of such textile.
Active learning presentations by 9 groups: What have you learned and remembered from other groups’ topics and presentations?
Aramid- high performance man made fiber, used for firefighter gear and military grade uniforms
Pinatex- non biodegradable leather alternative made from cellulose extracted from pineapple leaves
