Embodiment 1

[0064] A kind of preparation method of core-spun fire grass yarn, adopts such as Figure 1~3 For the device shown, the steps are as follows:

[0065] (1) The core yarn system is prepared in advance, the yarn is pulled out from the bobbin as the core yarn 10, which passes through the bottom of the pressure belt 3, the bell mouth 4, the rotary vortex nozzle group 5, and the groove drum 6 in sequence and is wound on the winding On the roller 7, pay attention to ensure that the core yarn 10 is in a straight state;

[0066] (2) Turn on the power, turn on the switch, drive the negative pressure conveyor belt, put the collected, washed and dried fire grass leaves with the suede side up, and place them on the negative pressure conveyor belt in the direction that the midrib 9 of the blade is perpendicular to the core yarn 10 At the same time, the air extractor works, and the fire grass blade 8 is adsorbed on the conveyor belt; the fire grass blade 8 is firmly sucked by the conveyor be...

Embodiment 2

[0074] A kind of preparation method of core-spun fire grass yarn, adopts such as Figure 1~3 The shown device has the same steps as in Example 1, except that the core yarn adopts a soluble vinylon filament yarn with a water melting temperature of 40 degrees Celsius (the core yarn in Example 1 is a non-soluble vinylon filament yarn).

[0075] In the final core-spun fire grass yarn, the fire grass fiber fleece in the yarn is tightly wrapped around the vinylon filament yarn, and the soluble vinylon filament yarn lives inside the fire grass yarn. Then it becomes a pure fire grass hollow structure yarn.

Abstract

The invention relates to a core-spun fireweed yarn and its preparation method and preparation device. The core-spun fireweed yarn is composed of a core yarn and a covering yarn, and the covering yarn is twisted from fireweed fiber velvet; the preparation method is as follows: : After the fire grass leaves are conveyed to the bottom of the core yarn with the suede side facing up, the core yarn is pressed to make it contact with the fire grass fiber velvet on the fire grass leaves, and the core yarn is twisted while conveying the fire grass leaves Make it roll on the fire grass fiber velvet on the fire grass blade, cover the fire grass fiber velvet on the surface, twist the core yarn covered with the fire grass fiber velvet on the surface to obtain the core spun fire grass yarn, and collect the core spun yarn at the same time Fireweed yarn; the preparation device includes a transmission assembly (including a mesh conveyor belt and a negative pressure suction device), a hook fiber assembly (including a hook fiber licker-in roller), a core assembly (including a pressure belt), a twisting assembly (for The core yarn that the surface is covered with fireweed fiber suede is twisted) and the winding assembly. The method and device of the invention are simple and can efficiently and automatically prepare the core-spun fireweed yarn.

Description

technical field [0001] The invention belongs to the technical field of textile engineering, and relates to a core-spun fireweed yarn, a preparation method and a preparation device thereof. Background technique [0002] The scientific name of fire grass is gerbera gerbera, and it is commonly known as "back white". The white fiber layer on the back of the leaf can be torn off the twisted thread, and it is one of the few fibers that can directly weave raw materials without any chemical treatment. Huocao fiber is also the natural fiber with the shortest single fiber length but used in the textile field. Huocao fiber has excellent properties such as soft and skin-friendly, moisture-absorbing, breathable, light and warm. [0003] However, the source of this precious raw material is relatively poor. Huowao is produced in Yunnan and Sichuan of my country. At present, it is mainly wild, and artificial cultivation has just started. Picking fireweed is not easy. Picking fireweed is ...
