Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

The preferred embodiment is shown in fig. 1, which is a tarpaulin for a garbage yard bedding bottom, comprising a base cloth layer 1 and an anti-corrosion coating 4, wherein a water filtering layer 2 and a water storage layer 3 are arranged between the base cloth layer 1 and the anti-corrosion coating 4, and the upper surface of the water storage layer 3 is provided with a water filtering and placing groove 31; swill generated by garbage penetrates through the base cloth layer 1, is filtered by the water filtering layer 2, and then is accumulated in the water filtering and collecting groove 31 of the water storage layer 3 to form fine water flow which is easy to collect. Wherein, the base cloth layer 1 is made of corrosion-resistant terylene and can be penetrated by swill; the water storage layer 3 is made of rubber cloth which has waterproof performance; the anti-corrosion coating 4 prevents bacteria in the ground soil from corroding the rubber cloth of the water storage layer 3, and the anti-corrosion coating 4 is preferably of an interpenetrating network structure formed by copolymerization reaction of various high-performance anti-corrosion materials and modified toughened heat-resistant resin.

The base cloth used for making the base cloth layer 1 is a latticed braided fabric formed by interweaving polyester weft threads 1.1 and polyester warp threads 1.2 as shown in figures 2 and 3; every other latitudinal interval distance in the polyester weft yarns 1.1 is provided with a latitudinal plied yarn 1.3a, and every other latitudinal interval distance in the polyester warp yarns 1.2 is provided with a longitudinal plied yarn 1.3 b; the weft plied yarns 1.3a are externally bound with first net yarns 1.4a formed by interweaving two yarns, and the warp plied yarns 1.3b are externally bound with second net yarns 1.4b formed by interweaving two yarns, so that double-layer protection is formed. In addition, a first three-loop knot 1.5a is arranged at the length of 1.2 of every two polyester warps of 1.4a of the first net thread 1.3a outside the weft-wise twisted thread; the length of every two polyester weft yarns 1.1 of the second net yarns 1.4b outside the warp-wise plied yarns 1.3b is provided with a second three-sleeve knot 1.5b, and the first three-sleeve knot 1.5a and the second three-sleeve knot 1.5b are made by a sleeve knot machine and used for separating the connection among all line segments, so that the fracture of individual line segments does not influence the performance of the whole net yarn. Wherein, the three sets of knots in two directions are distributed on two sides of the base cloth in a spaced mode. Preferably, the length of the weft separation distance is the same as that of the warp separation distance, so that a square grid is formed, and the tear resistance of each part is consistent.

In this embodiment, the cross sections of the warp-wise plied yarn 1.3b and the weft-wise plied yarn 1.3a are both as shown in fig. 4 and are composed of a core wire 1.3.1 and a plurality of externally wound windings 1.3.2; the core wire 1.3.1 is coated copper fiber, the copper fiber has good toughness, the tear resistance of the base fabric can be improved, and the coated base fabric is not easy to corrode by swill; the winding 1.3.2 is formed by twisting 3 bundles of nylon fibers with Z as shown in figure 5, and the nylon fibers have good wear resistance, good elastic recovery rate and low moisture absorption.
