The fabric that good Skeletal yarn is made into cloth cover after dyeing will appear a large amount of core-skin separation the case where make base face drop etc., especially
When core filaments ratio is higher and the dyeability of core filaments and cortical material dyeability have larger difference, core filaments degree of exposure is more tight
Weight, affects the quality of finished product；
The complete uniform extraordinary skeleton composite yarn of cladding is produced, theoretically tension force of core yarn should be bigger than outer wrapping fiber, preceding sieve
Outer wrapping fiber output speed should be big compared with core filaments at draw vice mouth, and can rotate around core filaments, in this way, when fiber strip is in twist triangle zone
