Based on the physical properties of Ni-Fe fiber, the orthogonal design was adopted to determine the parameters including roving twist, back zone drafting multiple and yarn twist, and the strength and wear resistance of the produced five kinds of yarns were tested and analyzed. The results show that to solve the problem of mixing uniformity of Ni-Fe Fibers, the suitable drawing numbers can be adopted. And the appropriate roving twist, spinning back zone drafting multiple and yarn twist are key factor of resultant yarn.

The effect of spinning speed on yarn quality at self-twist spinning system was investigated. The yarns were assessed for different characteristics using objective tests. The results show that yarn hairiness of self-twist yarn increases with the increase of spinning speed and yarn tenacity and extension decrease with increment of spinning speed. The results also show that yarn irregularity, yarn imperfections and yarn twist level have no obvious changes with the increasing in spinning speed. Furthermore, the longitudinal and cross-sectional shape of self-twist yarn were observed and the pictures show that S-twist and Z-twist zone have almost the same structure as the two-plied yarn at ring spinning system and no twist zone has an approximately 45mm length which can influence the strength of the self-twist yarn.

In this paper we will study 2-knots in the 4-sphere S4 which are obtained by roll-spinning 1-knots in the 3-sphere S3. The process of spinning was introduced by Artin[2] and generalized to twist-spinning by Fox [7] and Zeeman [20]. In [7] Fox introduced another variation of the spinning process, called roll-spinning. He only showed that the roll-spun figure-eight knot cannot be obtained by twist-spinning the figure-eight knot. Finally Litherland [14] described the general process of deform-spinning, and he gave a precise definition of roll-spinning. We remark that Fox's roll-spinning is not the same as Litherland's: Fox's roll-spun figure-eight knot is the symmetry-spun figure-eight knot in terms of [14].
