Forming process of high-wear-resistance yarn guide for elasticizer

Abstract

The invention discloses a forming process of a high-abrasion-resistance yarn guide for an elasticizer. The forming process comprises the following steps: 1, raw material weighing and taking: the raw materials comprise high-purity Al2O3, adhesives and additives including magnesium oxide and silicon dioxide; 2, mixing and granulating: granulating the weighed Al2O3, polyvinyl alcohol solution and additives, and filtering through a screen; 3, dry-pressing molding: extruding the fine powder obtained in the step 2 into a yarn guide mold according to the quantity, and carrying out pressurizing and pressure maintaining to form a green body; 4, sintering: heating in stages and preserving heat; and 5, surface treatment. The forming process of the high-abrasion-resistance yarn guide for the elasticizer is convenient to implement, the flowing capacity and adhesion of Al2O3 are improved through polyvinyl alcohol, the sintering capacity is improved through silicon dioxide and magnesium oxide, the internal structure of Al2O3 is uniform, the high-abrasion-resistance yarn guide is obtained, the service life of the yarn guide is prolonged, and the working performance of the elasticizer is improved.

Description

technical field [0001] The invention belongs to the field of manufacturing parts of textile equipment, and in particular relates to a forming process of a high wear-resistant wire guide used in a texturing machine. Background technique [0002] With the continuous improvement of living conditions, people's requirements for home textiles and fabrics are getting higher and higher. Various modified chemical fibers continue to enter people's lives, such as functional chemical fibers such as antibacterial, sunscreen, and shaping. Cotton and linen are also chemical spinning with different functions. In the fiber production process, every process is inseparable from the guide device, especially the guide device on the texturing machine, which needs to have the ability to withstand high speed and high wear resistance. , the texturing machine uses aluminum metal wire guides, but with the continuous improvement of the efficiency of textile machinery, that is, the increase in the speed...

[0002] With the continuous improvement of living conditions, people's requirements for home textiles and fabrics are getting higher and higher. Various modified chemical fibers continue to enter people's lives, such as functional chemical fibers such as antibacterial, sunscreen, and shaping. Cotton and linen are also chemical spinning with different functions. In the fiber production process, every process is inseparable from the guide device, especially the guide device on the texturing machine, which needs to have the ability to withstand high speed and high wear resistance. , the texturing machine uses aluminum metal wire guides, but with the continuous improvement of the efficiency of textile machinery, that is, the increase in the speed of the rollers, the service life of the aluminum wire guides is reduced, and the fibers have quality problems such as open wires and broken wires. Seriously affect the production cost and production capacity, the use of wear-resistant materials to make wire guides has been continuously explored
