What is dimensional change in textiles commonly referred to as?
Color fading
Dimensional stability
Texture alteration
Weight variation
Which type of shrinkage occurs due to the relief of tension imposed during the production process?
Progressive shrinkage
Relaxation shrinkage
Elastic shrinkage
Permanent shrinkage
During which cycle does relaxation shrinkage mostly occur?
After several washes
During the first care cycle
During the dyeing process
After long-term use
What happens to warp yarns in comparison to filling yarns during production in terms of tension?
Warp yarns are under less tension
Warp yarns are under the same tension
Warp yarns are under greater tension
Warp yarns are not affected by tension
Which fabric is mentioned as often having great relaxation shrinkage?
Silk fabrics
Wool fabrics
Cotton fabrics
Polyester fabrics
What is progressive shrinkage?
Why is it difficult to assess progressive shrinkage?
What is the usual cause of progressive shrinkage in textiles?
Chemical reactions within the fabric
Fiber movement within the textile structure
Exposure to high temperatures
Use of strong detergents
What happens to a textile when it is agitated while immersed in water?
It becomes colorfast
It undergoes progressive shrinkage
It increases in length
It becomes more transparent
What is felting caused by?
The interlocking of cotton fibers
The interlocking of synthetic fibers
The interlocking of hair (wool) fibers
The interlocking of silk fibers
What effect does felting have on wool fibers?
Makes them less entangled
Makes them easy to entangle
Makes them repel water
Makes them lose color
What is the result of fiber swelling in textiles?
The fabric becomes lighter and more elastic
The fabric becomes thin and elongated
The fabric shrinks and becomes thick and stiff
The fabric becomes smooth and shiny
What is expected to happen to fibers after drying, following swelling?
They should disintegrate
They should change color
They should come back to their original size
They should permanently elongate
Why might the fabric not return to its original size after swelling and drying?
Due to the application of dyes
Due to the loss of elasticity
Due to frictional forces between fibers
Due to the application of heat
What is the effect of a great degree of swelling on the fiber's bonding?
It strengthens the bonding within the fiber
It has no effect on the bonding within the fiber
It causes the bonding within the fiber to loosen
It makes the bonding within the fiber more flexible
Which materials have the greatest swelling shrinkage or growth?
Cotton and linen
Wool and silk
Rayon and acetate
Polyester and nylon
What is the maximum acceptable shrinkage for woven fabrics?
1-2%
2-3%
5-6%
No more than 2%
Which type of fabrics have a greater acceptable shrinkage, knits or wovens?
Woven fabrics
Knitted fabrics
Both have the same acceptable shrinkage
Neither have acceptable shrinkage
What is the trademark for cotton woven fabrics that indicates a certain standard of shrinkage?
Sanfor-Knit
Sanforized
Knit-Sanfor
Woven-Sanfor
What is the trademark for cotton and cotton blend knitted fabrics that indicates a certain standard of shrinkage?
Sanfor-Knit
Sanforized
Knit-Sanfor
Woven-Sanfor
What are the two types of dimensional change in fabrics?
Expansion and Contraction
Relaxation and Progressive shrinkage
Growth and Shrinkage
Elasticity and Plasticity
What are the subtypes of progressive shrinkage?
Stretching and Shrinking
Felting and Swelling
Expansion and Contraction
Elasticity and Plasticity
When evaluating dimensional change, how far apart should the pairs of marks be placed on the fabric or garment in the warp and filling directions?
20 cm apart
25 cm apart
30 cm apart
35 cm apart
How is the percentage of shrinkage/growth in the warp direction calculated after cleaning a fabric?
By measuring the distances between the marks before and after cleaning and then dividing by the original length
By calculating the average of the 3 measurements in the warp direction and comparing it to the filling direction
By calculating the average of the 3 measurements in each direction and then dividing by the original length
By measuring the distances between the marks after cleaning only
What indicates shrinkage or growth in fabric after evaluating dimensional change?
A positive value indicates growth, while a negative value indicates shrinkage
A negative value indicates growth, while a positive value indicates shrinkage
A positive value indicates neither growth nor shrinkage
A negative value indicates neither growth nor shrinkage
What causes fabric twisting, also known as skewness?
Uneven tensions during the cleaning process
Uneven tensions during the dyeing process
Uneven tensions introduced during the production process
Uneven tensions introduced during the cutting process
Why does fabric shrink or grow in different degrees?
Because of the quality of the fabric
Due to the uneven tensions introduced during the production process
Because of the temperature of the water during cleaning
Due to the type of dye used
What is the correct formula to calculate the percentage of fabric twist?
((A - B) + (A + B) / 2) x 100
((A + B) - (A - B) / 2) x 100
((A - B) / (A + B) / 2) x 100
((A - B) / ((A + B) / 2)) x 100
What will be the result if the left diagonal distance and the right diagonal distance of a fabric shrink or grow at the same rate after washing?
A large number of % fabric twist
A small number of % fabric twist
No change in % fabric twist
The fabric will be unusable
Which factor is not responsible for the test results of fabrics made of filament polyester often having a higher degree of fabric twisting?
The shrinkage of the fabric
The low warp and filling yarns' frictional behavior at intersection points
The smooth and slippery nature of filament polyester fibers
The color of the fabric
