Novel carpet yarn production process method and setting machine for superheated steam

Abstract

The invention discloses a novel carpet yarn production process method and a setting machine for superheated steam. The technical scheme includes that the method includes the steps: S1 enabling yarns to penetrate a yarn tension device; S2 feeding the yarns into a yarn flapping device or a bender, and laying the yarns on a running steel belt; S3 performing pre-evaporation and dehumidifying the yarnsby a dehumidification device; S4 performing heat setting by a steam setting cavity; S5 removing yarn moisture by a dehumidification fan; S6 storing the yarns on a yarn storage device, and winding theyarns to form a yarn cylinder by a winding machine. Temperature control electric heating rods are additionally arranged in the setting cavity, steam led in by a steam mechanism is heated to generatethe superheated steam, efficient and comprehensive heat setting of the yarns can be implemented by a setting mode under the combined action of steam and electric heating, an S-shaped conveying mechanism is arranged in the setting cavity, so that the yarns are set along an 'S'-shaped direction, the length of the setting cavity is shortened, the superheated steam penetrates the front surfaces and the back surfaces of the yarns, the yarns are sufficiently set, and setting efficiency is obviously improved.

Description

technical field [0001] The invention relates to the technical field of new carpet yarns, in particular to a new carpet yarn production process and a setting machine for superheated steam. Background technique [0002] In the production process of carpet yarn, twisting and setting technology will be applied. The setting machine is composed of yarn feeding device, setting cavity and yarn winding device. In the current setting principle, the yarn is spread on the conveyor belt at a certain density and passes through the shaping cavity in a straight line, and the yarn is shaped by contacting steam in the cavity. The steam is input through the steam generator and the pipeline, and the steam in the shaping cavity is output through the steam hole, and the switch can be controlled by the pneumatic valve. [0003] Since only steam is used for setting and the yarn in the setting cavity passes through the cavity in a straight line, so in order to ensure sufficient contact between the ...

AI Technical Summary

Problems solved by technology

[0003] Since only steam is used for setting and the yarn in the setting cavity passes through the cavity in a straight line, in order to ensure sufficient contact between the yarn and the steam in this process route, the setting cavity generally reaches more than 10 meters, and the steam flows from top to bottom In the process of passing through the yarn, the two surfaces of the yarn are heated unevenly. This kind of setting principle not only makes the softness and bulkiness of the yarn poor, but also the setting is not sufficient.

The surface of the woven carpet is granular, the lodging resistance is poor, the adsorption and permeability of the yarn to the dye is not good enough, and the color is relatively dull
