Description

Preparation method of knitted fabric with colorful effect
Technical Field
The invention relates to a knitted fabric, in particular to a preparation method of a knitted fabric with a colorful effect.
Background
Covering yarn: the core spun yarn is generally spun by using synthetic fiber filaments with good strength and elasticity as core filaments and wrapping short fibers such as cotton, wool and viscose fibers together for twisting. The core-spun yarn has the excellent performances of both filament core yarn and short fiber covering. It can utilize the excellent physical performance of core yarn chemical fiber filament, the performance and surface characteristic of outer covering short fiber, and make full use of the features of two kinds of fiber to make up their deficiencies. At present, the ring spinning core-spun yarn is the mainstream in industrial production, and the vortex spinning core-spun yarn and the air spinning core-spun yarn also have a certain scale.
Vortex spinning technology: the air jet vortex spinning machine is developed on the basis of air jet spinning, and the vortex spinning is free end spinning and belongs to a true twist structure. Air-jet vortex spinning principle: the air flow sprayed from the spray holes forms a negative pressure zone at the inlet of the nozzle, and the parallel fiber bundles drafted by the front roller are sucked into the nozzle under the action of negative pressure. The front end of the fiber bundle is drawn by the tail end of the yarn being formed around the guide needle and guided into the yarn-drawing tube, the rear end of the fiber bundle is acted by the axial force of high-speed eddy current, part of the fibers are laid down in an umbrella shape at the inlet of the yarn-drawing tube, the laid fibers are exposed in the swirling airflow ejected from the jet holes and are twisted on the yarn tail along with the rotation of the airflow, and the solid-twisted short fiber yarn is output. The vortex spun yarn has less hairiness, smooth surface and better anti-pilling performance than other spinning products; the moisture absorption is good. The fabric has good luster, softness and bone feeling, good dimensional stability and wear resistance.
Dotting yarn: yarns having color specks attached to the surface of the yarn are called speck yarns. Light color dots can be attached to the dark ground yarns, and also the dark color dots can be attached to the light ground yarns. The color dots used in the color dot yarn are generally made of various short fibers which are firstly made into particles, and the particles are added during spinning after being dyed. Because of the addition of the short fiber particles, the common yarn is thicker, and because of the existence of the short fiber particles, the fabric surface has obvious granular feel, and the wearing comfort is poor.
