The making of same spinneret differential linear density and differential shrinkage filaments is of great value to the wool-like researches of man-made filaments.
“But if you look at a silkworm, it only has one kind of spinneret,” she added.
The result indicates that the desired flat-like polyester filaments can be made by an reasonable design for spinneret micro-hole and high-speed spinning.
Nylon is meltspun. That is to say a molten mass of nylon, formed by melting nylon chips, is forced through holes in a spinneret.
Shine and flat polyester staple fiber was produced by using profiled spinneret and special spinning and drawing process.
Using NaSCN as solvent, acrylic fiber was produced by one-step wet spinning process. The effect of spinneret negative draw ratio on fiber formation was discussed.
Usually the number of holes in the spinneret determines the number of filament in the yarn.
Many tiny tubes connect each silk gland with a spinneret.
