Problems solved by technology

However, due to the fact that both sides have not been heat-treated, the surface is relatively smooth, and the construction method and construction conditions are limited. Generally, this double-sided smooth polyester spunbonded non-woven geotextile still has some problems in its application performance. : (1) easy to roll up during construction and paving; (2> easy to produce wrinkles during construction and paving; (3) insufficient bursting strength when used on uneven and irregular base surfaces
[0004] The existing method of using singeing to improve the performance of geotextiles is not widely used in the field of geotextile production, and the existing methods mainly have the following shortcomings: (1) uneven singeing; (2) the fabric is easy to change color and form paste (3) The main body of the fabric is easily damaged, which affects the performance of the fabric

Embodiment 1

[0009] The design weight of polyester filament spunbonded nonwoven fabric is 140 grams per square meter, and the width is 3.8 meters. After the previous process and acupuncture bonding, it enters the singeing process. The drying temperature is set at 85°C, the singeing cloth speed is 90 m / min, the flame temperature is 8000, and the distance between the flame and the cloth surface is 0.5 cm. The processed non-woven fabric can better adapt to the uneven base layer, resist the damage of external force during construction, has small creep, and can still maintain the original function under long-term load.

Embodiment 2

[0011] The design weight of polyester filament spunbonded non-woven fabric is 200 grams per square meter, and the width is 2.0 meters. After the previous process and acupuncture bonding, it enters the singeing process. The drying temperature is set at 90 ° C, the singeing cloth speed is 120 m / min, the flame temperature is 8500 ° C, and the distance between the flame and the cloth surface is 0.8 cm. The ratio of the processed product Compared with ordinary geotextiles, the performance has been greatly improved. It not only has good water permeability, but also can resist corrosion and aging, and its flatness and smoothness are also greatly improved compared with before.

Abstract

The invention discloses a singeing method of polyester spunbonded non-woven geotechnical cloth, and particularly relates to a singeing method of the polyester spunbonded non-woven geotechnical cloth for road pavement construction. A singeing device is additionally arranged in the technological process of producing the polyester spunbonded non-woven geotechnical cloth, so that the dried and hair-brushed double-surface smooth geotechnical cloth fabric is subjected to single-surface singeing. In singeing, the running speed of the fabric in the singeing device is controlled to be 45-150m / min, and the flame temperature is controlled to 800-900 DEG C; the distance between flames and the cloth surface is controlled to be 0.5-1.0cm; a product after singeing is improved greatly in the evenness, and also is improved greatly in tensile and corrosion resistance, can well adapt to the uneven basic layer, resist damage by external construction force, is low in creep, and can still keep the original functions under long-term load.

Description

technical field [0001] The invention relates to a singeing method of a geotextile, in particular to a singeing method of a polyester spun-bonded non-woven geotextile used for road pavement construction. Background technique [0002] At present, geotextiles are widely used in the construction of roads and bridges, but due to the limitations of their materials and construction conditions, general geotextiles have been unsatisfactory in many applications. With the development of modern technology and the deepening of research on road structure, people are looking for a process that can improve the application performance of geotextiles to get rid of this limitation. [0003] Polyester spunbonded non-woven geotextile is a polyester filament needle-punched non-woven geotextile, which does not contain chemical additives, has good mechanical properties, good water permeability, and can resist corrosion and aging; it has isolation, Anti-filtration, drainage, protection, stabilizati...
