What is the distinguishing feature between Satin and Sateen Weaves?
The warp-faced vs. weft-faced orientation
Why do Satin and Sateen Weaves have a bright appearance and smooth feel?
Using lustrous and fine count filament yarns
What characteristic contributes to poor seam strength in Satin and Sateen Weaves?
Thread mobility due to few binding points
Why is the use of move numbers necessary in constructing Satin and Sateen Weaves?
For selecting intervals in the weave pattern
What is the defining characteristic of Regular Warp Satin?
Definite move number throughout the repeat
How is Irregular Weft Sateen different from Regular Weft Sateen?
No definite move number throughout the repeat
What type of Satin has the prominence of warp floating on the fabric?
Warp Satin
What distinguishes Irregular Warp Satin from Regular Warp Satin?
No definite move number throughout the repeat
In the context of Sateen, what characterizes Regular Weft Sateen?
Definite move number throughout the repeat
What is the distinguishing feature of Irregular Satin in terms of moves?
No definite move number throughout the repeat
How is the warp represented on the design paper when it is over the weft?
By a cross or shaded area
What is the recommended procedure for taking thread density measurements on a fabric sample?
Take about 5 readings at different positions and use the mean value
Why should excessive stretching of the fabric be avoided during fabric analysis?
All of the above
How should threads be frayed off from the fabric sample during analysis?
By using common pins to displace the threads and then fraying them off
What should be done if the thread density in warp or weft direction is less than 20 threads per inch?
Count the threads in a larger area and find the mean threads per inch
When finding the crimp of the yarn, how much should the threads be stretched?
Only enough to remove the visible crimp of the thread
What happens after the counting of Move No. 2 is completed in the second end?
The adjacent right box is marked with up (Coloured Box)
How is the first warp end marked in a 1/4 (5 - End) Sateen with Move No. 3 weave?
1 Up (Coloured Box) and 4 down (Blank Box)
Where does the counting of Move No. to fill the third end start?
1st down after up in the second end
What is marked on the adjacent right box of the third end after completing the counting of Move No. 2?
Up (Coloured Box)
In the fourth and fifth Ends filling process, what pattern is followed?
Similar to how the first and second ends were filled
What happens to the rest of the boxes above and below the Coloured Box in each end?
Marked with down (Blank Boxes)
What is the mathematical expression used to calculate the weight of warp threads in ounces per square yard?
Weight of Warp (ozs) = ends per yard x (1+warp crimp) / (840 x warp count)
What is the mathematical expression used to calculate the weight of weft threads in ounces per square yard?
Weight of Weft (ozs) = picks per yard x (1+weft crimp) / (840 x weft count)
What is the mathematical expression used to calculate the weight of warp threads in grams per square meter?
Weight of Warp (gms) = ends/meter x (1+warp crimp) x warp count (tex)
What is the mathematical expression used to calculate the weight of weft threads in grams per square meter?
Weight of Weft (gms) = picks/meter x (1+weft crimp) x weft count (tex)
What is the alternative method described for calculating the GSM (grams per square meter) of a fabric?
By cutting a fabric sample of 5cm diameter and multiplying its weight in grams by 100
How is the weave design of a fabric determined according to the given information?
By examining the order of interlacement between the warp and weft threads on a design paper
This quiz covers the procedure of calculating the weight of fabric per unit area by determining the individual weights of warp and weft threads in ounces per square yard. Learn how to calculate the weight of warp and weft threads and how to add them to get the total fabric weight.
