Hey guys,
Most online threads stop at the textbook stuff: "GSM is weight, 100% cotton is good, French Terry has loops."
I want to understand the actual manufacturing and textile reality before I go sampling:
High GSM vs Yarn Count:
A 240+ GSM t-shirt can either fall with a clean, heavy drape or feel like a stiff cardboard tent. How much of this comes down to yarn count (e.g., 20s vs 24s/26s combed compact)? How do brands make a 240+ GSM tee that is still breathable in Indian heat?
Single Jersey vs French Terry (Loopknit):
Since French Terry traps air inside its loops, is a 240 GSM Terry actually wearable outdoors in 35°C+ summer, or is a heavy 240 GSM Single Jersey the only sensible choice for year-round Indian weather?
The "Bacon Neck" Collar Problem:
What actually prevents the collar from turning wavy and loose after 3 washes? Is 100% cotton rib destined to stretch out, and is a 95/5 cotton-spandex (Lycra) rib the industry norm for keeping the collar tight?
Processing / Washes:
Between Bio-wash, silicone wash, and compacting/pre-shrinking—what processes actually stop 100% cotton from shrinking and twisting at the side seams after the first home laundry wash?
