Why filament texturing methods are used?
Texturing is a treatment in which flat filaments are distorted to have loops, coils, curl or crimps along their length to gain increased bulkiness, porosity, softness and elasticity in some situations. After drawing, drawn filaments are wound with or without twist into a package.
What is natural filament?
A filament yarn is made of one or more continuous strands called filaments with each component filament running the whole length of the yarn. … Most of the synthetic fibres have been produced into the form of a filament yarn. Silk is the only major natural filament yarn.
Which is the strongest fibre?
With so many natural fibres known for its tensile strength, silk is the toughest natural fibre found in our nature. One of the natural fibres known to man is its woven fabrics from the silkworm’s or caterpillar’s cocoon. Other animals, like spiders, also produce this fibre.
What do you call a tightly twisted fibers?
Stretch yarns are frequently continuous-filament synthetic yarns that are very tightly twisted, heat-set, and then untwisted, producing a spiral crimp giving a springy character. Although bulk is imparted in the process, a very high amount of twist is required to produce yarn that has not only bulk, but also stretch.
What is man made filament yarn?
(a) By polymerisation of organic monomers to produce polymers such as polyamides, polyesters, polyolefins or polyurethanes, or by chemical modification of polymers produced by this process. (for example, poly(vinyl alcohol) prepared by the hydrolysis of poly(vinyl acetate)); or.
What is combed yarn used for?
Combed yarn is a yarn that has straight and parallel fibres. The process via which the yarns are created results in smoother, stronger and even more compressed, that is outstanding for weaving.
