(Problems to be solved by the invention) Woven fabrics made of glass fibers have high heat resistance and, on the other hand, have almost no stretchability, so that a high-density fabric cannot be produced. , JP-A-59-1
The spring yarn of 00726 cannot be applied because it requires a high temperature when glass fiber is used as the raw yarn and annealing is required to prevent thermal shock breakage.
The one disclosed in Japanese Patent No. 341 has a supporting fiber as a stretchable raw yarn and a glass short fiber spun on the surface of the yarn, which secures stretchability as a woven fabric. However, the glass bulky yarn disclosed in JP-A-62-33838 is mainly composed of a film-forming substance having an adhesive property in order to compensate for the defect of bulky which is elongated when tension is applied. Although it retains crimpability with a sizing agent, the sizing agent loses its sizing ability when used in a high temperature portion as described above, and has a drawback that it is easily elongated by tension, that is, when it is bent, and becomes a defective product. .

Alternatively, the present invention provides a method for producing a stretch yarn, which is obtained by subjecting a surface of a glass fiber to a treatment with a lubricant, and then untwisting the glass fiber to form a spiral shape or a wavy shape in a continuous glass fiber bundle.

The composition may be called a composition or the like, the diameter of the fiber is 3 to 24 μm, the number of single fibers constituting the strand is about 400 to 4000, and the twisting direction may be either S or Z. Twisting and heat annealing give a permanent set to the glass fiber bundle, and at a temperature lower than the lower limit of the treatment temperature described above, a spiral shape or a wavy shape cannot be formed, and at a temperature higher than the upper limit, the tensile strength is significantly reduced. As the treating agent after the temperature treatment, a textile oil such as a vegetable oil which imparts a normal lubricating property, a binder, other lubricating oil or a chemical cross-linking agent,
A treatment agent composed of these combinations is supplied to the glass fiber bundle, and then untwisted.
