Description
Technical Field
The invention relates to the technical field of plastic recycling and processing production, in particular to a shaping method of plastic woven base fabric.
Background
China is a large plastic pollution country and faces a very serious plastic pollution problem, so that China pays great attention to recycling of plastic materials, the plastic weaving industry is currently a very important plastic reprocessing industry in China, and the recycled high polymer plastic materials are processed into carpets, lawns, mats, clothes and the like through plastic weaving, so that the plastics can be recycled. The plastic woven base fabric industry is one of the main forces of the plastic woven industry, and the plastic woven base fabric is woven by processing recycled plastic, drawing the processed plastic into flat yarns and further processing the flat yarns on the base fabric, so that the plastic woven base fabric can be directly used or can be subjected to secondary processing on the base fabric, such as being made into carpets, artificial lawns and the like.
At present, the production process of the plastic woven base fabric mainly comprises the following processes: drawing wire, rolling wire and weaving into cloth. In the process, the yarns are stretched in the processes of wire drawing, wire coiling and weaving, so that the yarns generate internal stress, if the internal stress is not eliminated, the toughness of the base fabric of the finished product is lower, the base fabric is woven, after the base fabric is placed for a period of time, the base fabric is folded and deformed due to the retraction of the flat wires, the flat wires are broken in serious conditions, and the quality of the plastic woven base fabric is greatly influenced.

FIG. 1 is a flow chart of a method for shaping a plastic woven base fabric according to the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Example 1:
fig. 1 shows a flow chart of the present embodiment, and the setting method of the plastic woven base fabric related to the present embodiment comprises the following steps:
mixing single polypropylene resin or single polyethylene resin or polypropylene resin and polyethylene resin in proportion, and drawing the mixture into flat filaments by a wire drawing machine;
shaping for the first time: after drawing, heating and cooling the plastic flat wire conveyed on the wire drawing machine alternately through a hot roller and a cold roller, wherein the heating temperature is 45-80 ℃;
and (5) setting for the second time: after the plastic flat wires are rolled into a yarn cylinder, the yarn cylinder is placed into an oven to be heated for the second time, the heating temperature is 30-65 ℃, and the heating time is 1-3 hours;
and (3) setting for the third time: and after weaving the plastic flat yarns into a base fabric, repeatedly rolling the base fabric by using a heating roller, and heating the base fabric for the third time, wherein the temperature of the heating roller is 50-90 ℃.
Preferably, the heating temperature in the first setting is selected to be 60 ℃.
Preferably, in the second setting, the temperature of the oven is set to 50 ℃, and the heating time is 2 h. Before heating, preheating the oven, sending the yarn barrel into the oven when the yarn barrel is preheated to 30 ℃, continuously and slowly heating to 50 ℃, keeping heating at 50 ℃ for 2 hours, turning off the power supply of the oven, keeping the oven sealed, and naturally cooling the yarn barrel to room temperature in the oven. The second shaping process can enable the flat wire to retract as much as possible, eliminate the internal stress of the flat wire on the wire coiling machine due to stretching, and reduce the retraction of the flat wire in the subsequent weaving process.
