3. Ball-warp sizing.
4. Beaming, or winding a warp in an even sheet of threads on to a weaver’s beam for the loom.
5. Twisting-in or else drawing-in warp-ends in the loom.
If the threads of a new warp are similar in number and counts to those of the finished warp, and are to pass through the shedding harness and reed also in a similar manner, it is more economical to twist the threads of a new warp separately to the corresponding threads of the old warp, and then draw the twisted portion of the warp bodily forward through the healds and reed. If, however, the number of threads and counts are greatly dissimilar, or if a different drafting is required, then recourse must be had to drawing new warp-ends through the harness and reed.
Preparation of Mono-coloured Warps.
Warps of one colour may be prepared from either (1) warp-dyed and sized yarn, or (2) from hank-dyed and sized yarn.
1. (a) Warp-dyeing and Sizing.
The series of operations in this system are identical with those involved in the preparation of grey warps by means of ball warping, but with the additional process of dyeing immediately following the operation of warping, and are as follows:—
1. Winding yarn on to warpers’ bobbins.
2. Mill or other system of ball warping.
