Types of Warping
Direct Warping Denotes the transference of yarns from single-end yarn packages, wound packages, directly to a beam in a one step process. This means that there are an equal number of packages in the creel area as there are ends on the beam, except in the case of a magazine creel. A magazine creel connects the tail of one wound package to the beginning of a new wound package for an easy package transfer. from the wound packages in the creel.
A weavers beam may have upto 10,000 ends and if this were to be produced directly it would be necessary to have upto 10,000 creel packages.such an arrangement would be very difficult to accommodate and manage ;consequently it is normal practice to produce warpers beams which may contain upto about 1000 ends and these are combined at the slashing stage.because of the difficulties involved in combining the ends ,patterned warper beams are seldom produced on the direct system and any pattern that is produced is achieved by combining beams of various colors at the later stage of slashing.
This imposes limitations which can only overcome by changing to pattern weaving.
In sectional warping sections are made sequentially and because of this the process is rather slow ;it is the practice therefore to produce no more than is required to fill a single weavers beam.the result is that the sectional warping is used mainly for short runs or for complex color patterns.
Pattern, Band or Drum Warping
Because many warpers beams are combined in the direct system,this is usually regarded as a high speed process particularly suitable for single color work .providing the warpers beams are of single color ,it is possible to combine them to produce simple patterns distributed over the warp width.
Ball Warping is an intermediate process for storing yarn for transport ,dyeing or reserve; It does not produce a beam.the usual form is a cross wound cheese in which multiple ends are wound at the same time in a ribbon which contains perhaps 50 or 100 ends.
