Available in the market, elastic fabrics are predominantly designed applying SCY with a Z twist. Nevertheless, for items like socks and underwear, an S twist is frequently chosen due to one of a kind prerequisites of body structure.
Kangjiesi's three-proof fiber makes use of lower-temperature plasma modification technological know-how, that is a large-Strength nuclear physics know-how that bombards the fiber area to acquire physical modification and chemical activation energy groups (like -OH, COOH, C=O along with other free of charge radicals) Right after modification, the tetrafluoroethylene can also be modified by reduced-temperature plasma and deposited on the area with the fiber to advertise a grafting reaction Using the fiber molecules to form a totally built-in nanomembrane.
The technology of masking the fiber LYCRA® Together with giving a novel convenience ensures great elasticity and a full Restoration of form.
Throughout this period, operators will have to very carefully watch the conversation in between the 1st and next covering layers. The angle of wrap and pressure needs to be precisely calibrated to attain best protection without compromising the core’s stretch Homes. This fragile equilibrium requires substantial practical double covered yarn experience and technological knowledge.

Filament yarn is designed making use of one or more strands of filament that consistently run the whole duration of the fabric. Most filament yarns are artificial, except for silk.
Two, according to the unique gear is often divided into: mechanical covered yarn and air covered yarn.
