and fitting qualities is eliminated. Consequently, there is no subsequent bagging at the knees, nor any loss of shape in any other parts. Pre-boarding enables the stocking to fit the slenderest ankle without a shadow of a wrinkle.
A manufacturer determines that the stockings are adequately pre-boarded, by subjecting hose thus treated under actual operating conditions to a series of launderings such as they would receive when in service. The following points in the laundered hose denote the pre-boarding quality:-
1. The nylon fabric should not show wrinkles when laid flat on a table.
2. The stockings should not spiral or twirl when hung with the welt portion over a smooth rod, but should maintain their pre-boarded shape.
3. There should not be any rolling of the fabric along the reinforced parts of the foot, especially where the heel joins the sole.
The importance of good commercial stitch formation on the knitting machine cannot be over-estimated. This contributes to the clear, attractive appearance of dyed nylon hose. If non-uniform stitches are present in the grey (greige) hose prior to the pre-boarding process, such stitches will be set in the final stocking. This also applies in respect of oil spots, grease, or any mark contracted during the knitting process. These marks should be cleaned prior to pre-setting. Thus it may be seen that systematic cleaning of the knitting machine is necessary for the economical performance of nylon.
STOCKING BEAUTY TREATMENTBeauty is one of the chief selling points, and there is no doubt that before wear, comes first and foremost to a customer’s mind, “How will these stockings look on the leg—do they give eye appeal?”
Stockings from fine silk, rayon or nylon are very attractive in appearance. The fibre of these three yarns lends itself to the manufacture of sheer hosiery, and the stockings have that clinging quality which defines the contours of leg and ankle, making for a very trim appearance. One cannot really compare these fibres one with another—each has its own characteristics—yet it
