JPS588136A - Traveler for spinning frame - Google Patents

Abstract

PURPOSE:To improve the initial compatiblity of a merallic traveler with a ring and the lubricity and abrasion resistance, by using the metallic traveler having a film of an epoxy resin containing molybdenum disulfide. CONSTITUTION:A film 4 of an epoxy resin containing fine particles 3 of molybdenum disulfide having a particle diameter <=1mu is formed on at least the inner surface of to be in contact with a ring 2 a metallic traveler 1 for a spinning frame, e.g. a fine spinning frame or twisting frame. The thickness of the film is preferably 3-15mu. The content of the molybdenum disulfide in the resin is preferably 5-60%. The film is preferably formed by a dipping barrel from the viewpoint of the gloss, adhesivity and uniform thickness. EFFECT:No yarn breakage and fluffing or traveler burn.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a spinning machine traveler used in #4Fi spinning machines, yarn twisting machines, etc.

In recent years, with high-speed rotation and high-speed spinning aimed at high production,
The friction between the ring and the traveler is intense, and yarn breakage occurs due to fluctuations in the spinning force immediately after the start of operation, the traveler wears rapidly and its life is shortened, and the traveler flies off due to traveler burnout. There are drawbacks.

For this reason, it has been considered that the traveler is coated with PM plating to improve its wear resistance.
Although chrome plating has very high hardness, it has the disadvantage that it has poor compatibility with the ring, and in the early stages of spinning, the spinning force becomes extremely high and yarn breakage occurs frequently. Moreover, the plating surface is prone to cracks, which causes peeling and wear.
There were problems such as causing abnormal wear on the traveler.

The present invention eliminates the above-mentioned conventional drawbacks of t-S, and provides a trapeller for a spinning machine that has good initial conformability to the ring, is free from thread breakage, has excellent lubricity and wear resistance, is stable, and provides good spinning quality. Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

Embodiment FIGS. 1 and 2 show a front view and a cross-sectional view of a trapeller for a spinning machine according to the present invention, in which MO8! with a grain size of 1μ or less is coated on the inner surface of the horizontal or vertical metal traveler 1 that contacts at least the ring 2. The thickness of the epoxy resin coating 4 containing fine particles S! It is formed to a diameter below OJI (preferably 8 to 16μ) to form a trapella for a spinning machine.

Above M08! The formation of an epoxy resin film containing vcII'i is carried out by adhering by dipping a barrel, drying, and baking, or by spray coating, but forming a film by spraying has a drawback in that it is difficult to obtain uniformity of vcII'i adhesion. However, if using an immersion barrel, the abrasive and particles will be added to the epoxy resin solution below MO8! Barrel treatment is then carried out with the addition of a metal traveler to obtain a glossy coating with good adhesion and a uniform thickness (1 to 20 microns). If the thickness of the above coating is less than 20μ, the coating will wear off due to friction with the ring in the early stages of use, making it ineffective.If it exceeds 20μ, it will easily peel off due to the sliding contact between the ring and the traveler, causing abnormal wear. Become.

Furthermore, MO81! It is preferable that the content of the epoxy resin is in the range of 6 to sob in view of the relationship between its adhesiveness and lubrication performance.

The formation of the epoxy resin coating is not limited to the inner surface of the traveler that comes into contact with the ring, but may be formed on the entire surface of the traveler.

Since the present invention is configured as described above, an epoxy resin coating containing fine particles of molybdenum disulfide is formed on at least the inner surface of the metal trappeller that contacts the ring, so that the initial fitting is improved, particles are stabilized, and thread breakage is improved. , traveler burn is reduced.

In addition, by using epoxy resin as a film forming material for MOat, the adhesive performance with the traveler is improved and it does not peel off easily, reducing the frictional resistance between the traveler and the ring and greatly extending the life of the traveler and ring. I can do it. Furthermore, by obtaining a glossy coating by barrel dipping, the spun yarn is not contaminated, the lubricated yarn has good sliding, and the occurrence of yarn fuzz is reduced.
