- Patent Document 1 Japanese Patent Laid-Open No. 11-217739
- Patent Document 2 Japanese Patent Laid-Open No. 11-158744

- this method which is a conventional method, a plurality of glass fiber strands are aligned and continuously introduced into a liquid tank filled with an RFL treatment agent, and the RFL treatment is performed.
- the glass fiber strand is impregnated with the agent, ambient air is introduced between the glass fiber strands, and the presence of the entrained air prevents the glass fiber strand from being impregnated with the RFL treatment agent.
- the physical performance of the finally obtained glass fiber for reinforcing rubber products was adversely affected.
- the glass fiber strand is not sufficiently impregnated with the RFL treatment agent, the RFL treatment agent that cannot be completely impregnated remains on the surface of the glass fiber strand, and an excess RFL treatment agent exists.
- the excess RFL treatment agent may swell and form a scab-like film. This swollen film is peeled off by the friction between the coated glass fiber and the guide or traveler in the subsequent twisting process, deteriorating the working environment or deteriorating the appearance of the resulting glass fiber for reinforcing rubber products. .
- the glass fiber strand is a rotating body called a cake wound up in a drum-like shape, and this cake force is also used by pulling out the glass fiber strand.
- the sizing agent applied to the glass fiber strand moves toward the inner side (core side) and the outer side of the cake as the moisture evaporates. This causes a phenomenon in which a large amount of sizing agent adheres to the glass fiber strands (generally referred to as “middle”). Since the glass fiber strand with a large amount of sizing agent attached to this part has a relatively poor impregnation property with the RFL treatment agent, the above-mentioned problems that occur when the impregnation property is insufficient tend to be remarkable. For this reason, a certain amount of glass fiber strand with a large amount of sizing agent attached to the innermost and outermost parts of the cake is removed. And had to be discarded, which led to a drop in yield.
- a tension such as a disk tensor is used to align the glass fiber strands while applying a uniform tension.
- Tension each glass fiber strand with a compensator if the load on the disk tensioner is too large, the glass fiber strand will be damaged, so the load must be made as small as possible. As a result, it becomes difficult to align the glass fiber strands while always applying a uniform tension, resulting in variations in how the tension is applied. Such variations in tension may adversely affect the physical performance of the final glass fiber for reinforcing rubber products, particularly the tensile strength.
- the object of the present invention is to prevent the glass fiber strand from being uniformly and sufficiently impregnated with the RFL treatment agent and preventing the excess RFL treatment agent from remaining on the surface of the glass fiber strand and peeling off.

Further, in Example 1, it can be seen that when the glass fiber strands of the inner part and the outer part of the cake are used, the influence of migration with a small number of blisters is small. This can be presumed to be due to the improved impregnation of the RFL treatment agent into the glass filament.

- Example 2 As shown in Table 2, it can be seen that Examples 2 and 3 have higher tensile strength than Comparative Example 2. This is because, in the examples, the degree of impregnation of the RFL treatment agent into the glass fiber strand is good, and there is no variation in tension when arranging a plurality of glass fiber strands as in the prior art. Seems to be due to. [0097] In Example 2 in which the relationship between the count of the glass fiber for reinforcing rubber products and the cross-sectional area satisfies the relationship of the above formula (1), the example 2 satisfies the relationship of the above formula (1). It can be seen that water resistance is better than 3. This seems to be because the adhesion between the lower twisted yarns constituting the glass fiber for reinforcing a rubber product of Example 2 is increased, and the infiltration of water into the fiber is suppressed.
- the reinforcing glass fiber of the present invention can be suitably used as a reinforcing material for various rubber products such as a rubber belt including a timing belt and a rubber tire. It should be noted that the entire contents of the specification, claims and abstract of Japanese Patent Application No. 2005-358718 filed on December 13, 2005 are cited here as the disclosure of the specification of the present invention.
