Embodiment 1

[0018] Example 1: After the polyester fiber is changed from solid to liquid at a high temperature of 280°C, the melt is sent to a filter through a high-pressure screw extruder for filtration, and the filtered melt is mixed evenly to make the viscosity consistent After the inorganic monomer is added, the melt passes through the high-pressure metering pump, and the spinning assembly sprays the melt, and the sprayed melt is pressed and cooled by a press, and then cut to obtain polyester cloth; the pyrophyllite is melted in a kiln to form The glass solution is transported to the porous plug plate through the channel after removing air bubbles, and then drawn into glass fiber strands at a high speed. The glass strands are evenly arranged and placed in a heating furnace for heating. After heating, they are pressed by a pressing machine to produce glass fibers. Cloth; Spray the extension agent on both sides of the glass fiber cloth, the glass fiber sprayed with the extension agent is ...

Abstract

The invention provides a producing method of a high-extension felt base fabric. The producing method comprises the steps that polyester fibers are converted into liquid from solid at the high temperature of 280-330 DEG C, the molten body is transported by a high-pressure screw extruder to a filter to be filtered, the filtered body is mixed evenly, after the viscosity of the molten body is uniform,inorganic monomers are added, the molten body passes through a high-pressure metering pump, a spinning assembly sprays out the molten body, and the sprayed molten body is pressed by a pressing machine, cooled and cut to be prepared into a polyester fabric. According to the producing method, glass fibers are added to a conventional felt base fabric, the extension strength can be improved to a great extent, so that the produced high-extension felt base fabric is high in elastic coefficient, large in elongation length within an elastic limit and high in extending strength and accordingly absorbslarge impact energy, and the extending rate can be increased to a great extent by cooperating with an extending agent.

Description

technical field [0001] The invention relates to a production method of a high-stretch linoleum base cloth, which belongs to the field of textiles. Background technique [0002] In the prior art, the linoleum base fabric is a kind of non-woven fabric, which can also be called: (felt base fabric, linoleum base fabric, waterproof base fabric). Polyester linoleum base fabric is a kind of non-woven fabric product processed by 100% polyester staple fiber through carding, acupuncture reinforcement, dipping and shaping. 900m-1650m, with a thickness of 0.6-1.4g, it is the main base of the popular waterproof membrane (SBS, APP coating), but the existing linoleum base fabric has insufficient strength and elongation. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a production method of high-stretch linoleum base cloth to solve the problems raised in the above-mentioned background technology. The pres...
