THE INFLUENCE OF TUCK STITCHES NUMBER ON THE PROPERTIES OF KNITTED FABRIC

Abstract

The establishing of the influence of the number of took loops in the repeat of combined interloping on the  structure`s  parameters  and  the  properties  of  the  weft  knitted  fabric,  which  is  formed  by  alternating courses of rib 1 + 1 and half-cardigan, is the purpose of the work. All knitted samples have been produced on a  10-gauge  flat  bed  knitting  machine  from  32x2  tex  semi-wool  yarn.  Methodology.  The  study  of  the structure`s parameters and the relaxation characteristics has been carried out according to standard methods after providing the fabrics with conditionally equilibrium state by wet-heat treatment. The influence of the number of tuck loops in the interlooping repeat on the structure`s parameters and properties of weft knitted  fabric  was  determined  as  a  result  of  this  study  and  mathematical  dependences  were  obtained  to
determine the value of indicators. The increasing the number of tuck loops in the repeat leads to an increase in the thickness and, accordingly, the surface density. The values for half cardigan, which loops on one side are tuck, are 25% higher than for rib 1+1.The increasing the number of tuck loops in the repeat leads, as well, to a decrease in the difference in the stretchability in different directions. The full deformation of half cardigan is almost the same both course-wise and walewise and it is 140 ÷ 150%. Scientific novelty. The influence of the number of tuck loops in the repeat on the structure`s parameters and on the stretchability value of weft knitted fabric of a simple combined interlooping, which is formed by the alternation of courses of rib and half
cardigan  in  different  ratios  has  been  established  in  this  work.  Practical  significance.  The  established influence of the number of tuck loops in the repeat of a simple combined interlooping on its properties can be used in the creation of new knitwear and the prediction of their performance.
