（3）The impact of the yarn to preparation for the tension force of heart yarn feeding spinning frame
Spinning process SMIS yarn tension is likely to result in greatly very much yam surface continuity cotton knot and yarn defect, and this yarn defect is to garment material
For be difficult to quasi-complement, also can cause that " eccentric type " or " dew core pattern " etc. are serious to coat bad phenomenon simultaneously.Cladding is bad
The dyed rear cloth cover of fabric that Skeletal yarn is made into occurs that the detached situation of substantial amounts of core-skin makes base face fall etc., particularly core filaments
When ratio is higher and the dyeability of core filaments has larger difference with cortical material dyeability, core filaments degree of exposure is even more serious,
Have impact on the quality of finished product；
Produce and coat completely uniformly extraordinary skeleton composite yarn, tension force of core yarn should be bigger than outer wrapping fiber in theory, and front roller clamps
At mouthful, outer wrapping fiber output speed should be big compared with core filaments, and can rotate around core filaments, so, when fiber strip is coaxial in twist triangle zone
It is ensured that core filaments are always positioned at twisting center and keep straight configuration during composite twist.
In order to study further heart yarn feed spinning frame tension force to preparation yarn impact, we carry out following examination
Test, be specifically shown in Table 3
The impact testing result of the yarn to preparation for table 3 tension force of core yarn
As seen from the above table, with the increase of tension force of core yarn, first rising occur in the prepared fracture strength of yarn and extension at break
Downward trend afterwards.Because core filaments are in, in skeleton composite yarn, the state more stretched, and by twisting and outer wrapping fiber shape
Become a certain degree of looping effect, core filaments apply the composite yarn that certain tension force advantageously forms good covered effect, to resultant yarn
Intensity plays positive effect.But when tension force of core yarn exceedes certain scope, with the increase of tension force of core yarn, it is subject to inside core filaments
Prestressing force increase, the yarn therefore prepared ultimate strength declined, covered effect has also been deteriorated simultaneously.Through anti-
Multiple testing and verification, tension force of core yarn is best with 8CN.
When heart yarn feeding tension force reaches 8CN, it is optimum feeding tension force；Can be very good to solve skeletal composite
Coat the bad, quality problems such as nude silk, hollow yarn, wire ring nose.
