Zephyr

A fine fabric of plain weave used for dresses, blouses, and shirtings and made in various qualities. A typical zephyr has coloured stripes on a white ground and exhibits a cord effect made by the introduction of coarse threads at intervals.

Zero-Twist

Twistless devoid of twist.

Zero-twist yarn

1. A continuous-filament single yarn in which there is no twist.
2. A multi-fold yarn in which there is no folding twist.
note 7: Some fibrous yarns are described as twistless, since the fibres may be held together by adhesive temporarily e.g., until incorporated in fabrics. Varieties of core-spun yarn and scaffolding yarn have appeared with this description after solvent-removal of one component.
note 2: Zero-twist continuous-filament yarns usually become partially twisted by over-end withdrawal, e.g., from a pirn in a loom shuttle. (See also twistiess yarn.)

Zibeline

Zimmer Flatbed Printing Machine (Peter Zimmer)

A carpet printing machine that uses flat screens and dual metal-roll squeegees. The squeegees are operated by electromagnets to control the pressure applied. The unit also has a steamer for dye fixation. The Zimmer flatbed machine is normally used for carpets of low to medium pile heights. Very precise designs are possible but speeds are slower than with rotary screen printers.

Zimmer Rotary Printing Machine (Johannes Zimmer)

A three-step rotary carpet printing machine consisting of (1) rotary screens with small diameter steel-roll squeegees inside with pressure adjusted electromagnetically for initial dyestuff application; (2) infrared heating units to fix dyes on the tips of the tufts; and (3) application of low-viscosity print paste followed by steaming for complete penetration of dyes into tufts.

Zimmer Rotary Printing Machine (Peter Zimmer)

A rotary carpet printing machine in which each rotary screen has a slotted squeegee inside to feed print pastes through the screens to the carpet. Pressure of the print paste is adjusted by hydrostatic head adjustments.

The teeth are carried in two zip fastener tapes that run the length of the zip and which are usually stitched into apparel and other textile products.

Zip fastener tape

A narrow fabric which has a high lateral strength, and may be woven or knitted, being so constructed as to provide at one selvedge, for the suitable embodiment of the fastener elements (see zip).
