Embodiment 1

[0057] In this embodiment, the selected viscosity is 0.700 fiber-grade PET slices to produce the base fabric, the spinning metering pump is 15 turns, the production line production speed is 14m / min, and the net laying weight is 100g / m 2 .

[0058] The specific production method is as follows:

[0059] Base fabric processing, PET slices are made into base fabric through the processes of crystallization drying, melt extrusion, spinning cooling, filament laying, acupuncture reinforcement and tentering;

[0060] Functional coating treatment, the base fabric is made into the tarpaulin through the processes of hot rolling and shaping, functional finishing, knife coating and calender cooling;

[0061] Among them, the crystallization temperature of crystallization drying is 162°C, the crystallization time is 30min, the drying temperature is 172°C, and the drying time is 8h; the process temperature of each zone of the extruder for melt extrusion is shown in Table 3; the spinning proce...

Abstract

The invention discloses a tarpaulin taking a filament spunbond nonwoven fabric as the base cloth and a production method thereof. The tarpaulin comprises a base cloth layer and a functional coating. The base cloth layer is made of filament spunbond nonwoven fabric, which is prepared from PET with a viscosity of 0.69-0.71. The provided tarpaulin takes nonwoven fabric as the base cloth and has the advantages of good flexibility and lightness. Compared with conventional PE and PVC tarpaulins, the provide tarpaulin has the characteristics of high strength, good wear resistant performance, and better aging resistant performance (compared with a PE woven double membrane tarpaulin).

Description

technical field [0001] The invention relates to the field of composite tarpaulins, in particular to a tarpaulin with filament spun-bonded non-woven fabric as the base cloth and a production method thereof. Background technique [0002] In recent years, the rapid development of new materials and production technologies has improved the variety and quality of industrial textiles in China. As a traditional category of industrial textiles, tarpaulins have also developed rapidly. However, judging from the use of its base fabric, it is still mainly the coated canopy material of chemical fiber warp knitting and woven fabric coated with polyvinyl chloride or polyethylene. There are mainly the following technological processes: [0003] (1) PE tarpaulin [0004] Generally refers to color striped cloth, coated with PE film on both sides of PE woven cloth. to 6m), light in weight, the disadvantage is: it is not durable, and water leakage may occur after one use; [0005] (2) PVC tar...
