“…The machine tightness factor (MTF) is defined as: ' where n~ is the number of needles .in the knitting operation in the SKC, and SCSL is the structural cell stitch length or the length of yarn knitted into the SKC. The significance of Equation 3 is that, in effect, the term n~ ,/SCSL is a measure of the average length of yam knit by any one needle forming a loop or stitch in the SKC. Consequently, values of MTF vary over approximately the same range as the equivalent values for the plain-knit structure.…”

“…' The present work describes the reactive dyeing of wool with several a-substituted anthraquinone derivatives. The reactivity of anthraquinone derivatives substituted in the a-position by a halo, nitro, hydroxy, and sulfonic acid group is well known [3,17]. Al-'though several reactive dyes are known wherein the principle of nucleophilic substitution of an aromatic nucleus has been utilized ( 2,16], to our knowledge only one patent [ 10] describes reactive dyes for wool based on the nucleophilic substitution of the alpha substituent in the anthraquinone derivative by wool…”

Tumble-drying from the wet fabric state is shown to be a reasonable means of fully-relaxing rib structures. By this technique, an approximate discrimination can be made between dimensional changes due to relaxation and felting of allwool rib structures. Upon washing from the fully-relaxed state, untreated fabrics felt immediately due primarily to loop-length changes and not by changes in loop shape. Felting rates depend strongly on machine tightness factor (MTF) and to a lesser extent on fiber quality and yarn twist.To ensure machine washability of rib structures to within the limits of ± 8% area shrinkage and ± 5% linear shrinkage over 10 machine-wash and tumble-dry cycles, yarns must be treated against felting at a high level of treatment. Further dimensional changes in washing from the fully-relaxed state are due to residual relaxation and not felting. Occasional fabrics, particularly loosely knit structures, exceed these chosen shrinkage limits. To guarantee machine washability of rib structures, a fully-relaxing procedure of two cycles of wetting and tumble-drying is recommended.Under most conditions of relaxation and washing, the dimensional behavior of shrink-resist-treated rib structures is anisotropic, i.e., length shrinkages are generally associated with width expansion. A possible reason for this behavior is presented in this paper.

“…Three papers in the present series [2,3,4] have contributed to this knowledge, and one of these [2] gives a general introduction to the subject. By contrast, there seem to be no published data about the felting shrinkage behavior of hand-knitted fabrics, although again it is to be expected that similar relationships will hold to those which have been shown for machine-knits.…”

Hand-knitted fabrics were made on three sizes of needles using shrink resist-treated and untreated wool yams of three counts. The dimensional constants and felting shrinkage behavior of the fabrics were determined. In general, the properties were similar to those of machine-knitted fabrics, although in all states of relaxation, the course-spacing was less for the hand knits, and the dependence of shrinkage rate on cover factor was also somewhat lower than for machine knits.
