Problems solved by technology

[0002] At present, many glass fiber production methods are made by processes such as drawing, drying, twisting, back reforming, and joint stocking. This production method adopts a single drawing method and back reforming before joint stocking. The output glass fiber bobbin package is only 0.4Kg, and the quality is not good, mainly has the disadvantages of large count fluctuation, hairiness, loose filaments, breakage, low tensile strength, etc.

Embodiment Construction

[0023] The present invention will be further described below in conjunction with embodiment.

[0024] Heating and melting: put the alkali-free glass balls into the ball adding machine for secondary melting, control the temperature of the molten glass furnace in the crucible and heat it to 1300°C, the main components of the alkali-free glass balls are shown in the table below (1) The main components of the alkali-free glass balls Ingredients: .

[0025] Loss plate control: control the working temperature of glass liquid flowing out of the leak plate at about 1100°C, the inner diameter of the leak hole is 1.35mm, and the leak plate with 392 holes is drawn into a monofilament, and the temperature of the leak plate is adjusted through the control section of the diameter of the monofilament , The head speed of the wire drawing machine.

[0026] Oiling and soaking: pass the single fiber flowing out of the bushing plate through a roller oiler, and soak it with a sizing agent. The ...

Abstract

The invention provides a method for directly producing fiberglass yarns. In the prior art, protofilaments are degraded and then are stranded together according to the conventional manufacturing method. Different from the conventional manufacturing method, protofilaments are drawn firstly and then are twisted and stranded together. In the traditional market, the filament drawing operation is conducted in the single drawing manner. That means, only one protofilament cylinder is drawn out of a filament drawing handpiece each time. According to the invention, the original tank-furnace filament drawing method of significant investment is applied to the crucible process of small investment, while a paraffin type impregnating compound coated with the protofilaments is modified as a starch type impregnating compound. Therefore, the production efficiency is increased and the tensile strength is improved. the number of spools is increased and the production cost is lowered. Moreover, the yarn hairiness, filoselle, breakage and other phenomena of fiberglass yarns are reduced.

Description

technical field [0001] The invention relates to a production method of continuous glass fibers, in particular to a production method of direct glass fibers. Background technique [0002] At present, many glass fiber production methods are made by processes such as drawing, drying, twisting, back reforming, and joint stocking. This production method adopts a single drawing method and back reforming before joint stocking. The output glass fiber bobbin package is only 0.4Kg, and the quality is not good. It mainly has the disadvantages of large count fluctuation, high hairiness, loose filaments, breakage, and low tensile strength. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, apply the large-investment pool kiln drawing process to the small-investment crucible method, change the traditional paraffin-type sizing agent into starch-type sizing agent, and change the traditional single-drawing method to Tw...
