Abstract

The invention discloses a device for preparing imitation down and a preparation method thereof, comprising: an extruding device, the extruding device is equipped with a molten polymer, and a branching component is arranged outside the outlet of the extruding device, and the polymer is extruded After the device is extruded, it is in the shape of silk, and it becomes velvet under the processing of the branching component. The device and the metal ring are respectively connected to a high-voltage power supply; the knife sets of the split components are symmetrically arranged on both sides of the velvet, each knife set has a blade and the knife sets rotate synchronously, and the intersection of the blades on both sides of the velvet is located on the route of the velvet On the blade, there is a built-in heating device. The device mentioned in the present invention can make the polymer of the extruding device form velvet, and several relatively static cavities are formed in the polymer, thereby simulating the structure of down and improving the thermal insulation performance of imitation down.

Description

technical field [0001] The invention relates to the field of textile preparation, in particular to a device for preparing imitation down and a preparation method thereof. Background technique [0002] Down is a mixture of "feather" and "down". Feathers are flakes, which play a supporting role in the down and allow the down to rebound quickly; and down are down flowers, which are the body and value of down. The velvet flower is a three-dimensional spherical structure consisting of a velvet nucleus and many velvet filaments emitted, similar to a dandelion. Velvet is made up of thousands of tiny scales, each of which is hollow. There are many rhombus knots on each velvet silk, and these rhombus knots are filled with stagnant air. At the same time, a large amount of air will be fixed between the velvet silk and the velvet flowers. This is the secret of why down is so warm. But because of its small quantity and high price, it is far from satisfying people's increasing materi...
