Dove and Rose jacquard-woven silk and wool double cloth furnishing textile, designed by William Morris in 1879. [1]Double cloth or double weave (also doublecloth, double-cloth, doubleweave) is a kind of woven textile in which two or more sets of warps and one or more sets of weft or filling yarns are interconnected to form a two-layered cloth. [2]
The advantage of this type of weaving is that water power is cheaper where water is directly available on site. Picks per minute can reach as high as 1,000. Rapier loom: This type of weaving is very versatile, in that rapier looms can weave using a large variety of threads. There are several types of rapiers, but they all use a hook system ...
A rapier loom is a shuttleless weaving loom in which the filling yarn is carried through the shed of warp yarns to the other side of the loom by finger-like carriers called rapiers. [1] A stationary package of yarn is used to supply the weft yarns in the rapier machine. One end of a rapier, a rod or steel tape, carries the weft yarn.
The process here is similar to that found in one of Arkwrights Water frames, though the size of the ring, spindle and traveller are predictably larger. Alternatively a 'twiner' is used: this is a modified spinning mule and is mainly consigned to the doubling of warp thread. [ 10 ]
With each weaving operation, the newly constructed fabric must be wound on a cloth beam. This process is called taking up. At the same time, the warp yarns must be let off or released from the warp beams. To become fully automatic, a loom needs a filling stop motion which will brake the loom, if the weft thread breaks.
Viking longships used wool for sailcloth. The cloth was woven in one of three ways, according to locality and tradition: plain weave with individual threads going over and under each other, three-shaft twill with two threads going over and under at each cross thread, and four-shaft twill with thread interwoven with two threads at a time in either direction.
Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...
A loom from the 1890s with a dobby head. A dobby loom, or dobbie loom, [1] is a type of floor loom that controls all the warp threads using a device called a dobby. [2]Dobbies can produce more complex fabric designs than tappet looms [2] but are limited in comparison to Jacquard looms.
