Embodiment 1

[0024] A polyester fiberglass geotextile, the polyester fiberglass geotextile is formed by uniformly mixing glass fibers and polyester fibers and bonding and pressing them through a binder, the glass fibers, polyester fibers and binder The ratio of parts by weight is 5-7:2.5-4:0.5-1; wherein, the fineness of the glass fiber is 11-13 microns and the length is 50 mm; the fineness of the polyester fiber is 4D (D is denier Neil, used to indicate the fineness of the yarn, equivalent to 9000 meters / 4 grams), the length is 65-70 mm.

Embodiment 2

[0026] This embodiment is several optimizations on the basis of embodiment 1. For the same part as embodiment 1 in this embodiment, please refer to the content disclosed in embodiment 1 for understanding. The content disclosed in embodiment 1 should also be used as this The content of the embodiment will not be described repeatedly here.

[0027] Several optimal ratios of glass fiber, polyester fiber and binder in parts by weight in this embodiment are 5:4:0.5; 7:2.5:1 and 5.7:3.5:0.8, respectively.

Embodiment 3

[0029] This embodiment is an improvement made on the basis of Embodiment 1. For the same part as Embodiment 1 in this embodiment, please refer to the content disclosed in Embodiment 1 for understanding, and the content disclosed in Embodiment 1 should also be used as this embodiment. The content of the example will not be repeated here.

[0030] In this embodiment, the binder is polyester powder, which is a polyester powder binder produced in Japan "Kao powder". The polyester powder index is: the softening point is 120 degrees Celsius, and the melting point is 260 degrees Celsius. In order to increase the penetration ability of the binder powder, the binder powder is combined according to different particle sizes, so that the binder is evenly distributed in the glass fiber and polyester fiber, and the breaking strength of each point of the polyester fiberglass geotextile is improved. and elongation at break consistency. The combination of the different particles of the binde...

Abstract

The invention relates to a polyester glass fiber geotextile and a production method thereof. The geotextile is prepared by uniformly mixing glass fibers and polyester fibers, bonding with a bonding agent and pressing, wherein the weight part ratio of the glass fibers to the polyester fibers to the bonding agent is (5-7):(2.5-4.0):(0.5-1). The production method of the polyester glass fiber geotextile comprises the following steps of: preparing glass fibers and polyester fibers according to the weight part ratio; opening and mixing; carding, molding and feeding into a conveying mesh belt; bonding; heating; performing cold rolling; cooling; and winding, wherein the bonding treatment comprises spreading treatment and permeating treatment. The polyester glass fiber geotextile has the advantages of uniform fiber distribution, high breaking strength, high breaking elongation consistence, remarkable waterproofing function and suitability for road surfaces; and by adopting a dry production method, water resource is saved, drainage of waste water is avoided, environmental pollution is avoided, bonding agent mixing equipment used in conventional production is eliminated, and the equipment investment is low.

Description

technical field [0001] The invention belongs to the field of chemical fiber non-woven fabric production, and in particular relates to a polyester glass fiber geotextile and a production method thereof. Background technique [0002] Polyester fiberglass geotextile is a new type of composite geotextile developed after geotextile, geogrid, and strip polymer. It has good compatibility with asphalt, and can be used in highways, airports, parking lots, etc. It is mainly used to delay the generation of reflective cracks on the road surface, and to give the road surface a super waterproof layer, and it can be crushed into fine pieces for recycling , without increasing costs. At present, the use of polyester fiberglass cloth in my country has just begun to show excellent performance. However, there are very few manufacturers of polyester fiberglass cloth in my country, and there are only 2-3 companies that have passed the quality standard, and all of them are produced by "wet metho...
