What are the main sewing threads commonly used in flame retardant and fireproof tarpaulins?

As the weather gets colder, the flame retardant tarpaulin can still be used in winter, and it is easy to use and install, because there are grommets on the edges, and it is easy to fasten it with a rope, so the flame retardant tarpaulin has advantages. increasingly widespread. From the name of the flame retardant tarpaulin, it can be seen that there are flame retardant components inside, but what are the flame retardant components of the flame retardant tarpaulin? After investigation, it was shown that although flame retardant tarpaulins are all added with flame retardants, the type of flame retardants needs to be added according to the situation. Blend of flame retardants. In order to consider the cost, general enterprises will try to use a variety of flame retardants to compound the fire protection requirements, so as to achieve the same flame retardant effect. Flame retardant fireproof tarpaulins are very similar to ordinary tarpaulins, and their materials can reduce the flammability of the tarpaulins. These tarps are UV-treated to prevent aging caused by sun exposure. Even with constant use in strong sunlight, it will last for many years, and it is also waterproof, providing excellent rain protection and resistance to all acidic liquids that can harm the tarp and the items it contains. Tarpaulin, actually made of rough fabric, was widely used in sails at first. In modern times, people also bring tarpaulins when they go out camping or traveling. The most important thing for plastic tarpaulin is to have an excellent performance, so that it can play a greater role in the process of use and be welcomed by users. In order to enhance the use effect of the flame retardant and fireproof tarpaulin, various additives will be added during the production, and the antistatic agent is one of them. What are the main methods for adding additives to flame retardant and fire retardant tarpaulins? 1. Coating method: There are four processes of cleaning and dispensing, coating and drying. (1) The antistatic agent is prepared into a solution with a concentration of 0.2~2% with ethanol, ester or water. The concentration of the solution should be as thin as possible under the premise of ensuring the antistatic effect, because the solution with high concentration will Sticky, easy to absorb dust. (2) Coating Select the coating method according to the shape of the product. Commonly used coating methods include direct method, dipping method and spraying method. The direct method is to apply the antistatic agent liquid on the product with tools such as cotton cloth, flannel, brush and roller. (3) Cleaning In order to obtain a uniform and dense antistatic agent coating film, before painting the antistatic agent, the plastic surface needs to be cleaned to remove all surface dust, grease, etc. It can be cleaned with a neutral detergent solution of about 1%. After cleaning, it needs to be placed in a clean room to dry. 2. Blending method: It is to mix the antistatic agent with the resin and then process it into a product with antistatic properties. Commonly used antistatic agents are cationic and zwitterionic. The antistatic agent is easily hygroscopic and contains a corresponding amount of water. In the molding process, the presence of a small amount of water will cause the quality of the product to decline, so the antistatic agent should be fully dried before adding it to the resin. It can be dried for 4 hours under the hot air of 70-80℃. We all know that the same kind of tarpaulin is often different in terms of materials. If the materials used in the production of plastic tarpaulins are different, there will also be some performance differences when used. The problem, in addition to paying attention to its materials, is to pay attention to its performance in the production process. If only good production materials are used, and there is no good production process, then the flame retardant and fireproof tarpaulin will not have good quality performance. After the tarpaulin is used for a long time, it is easy to be damaged, and it needs to be repaired at this time, and the sewing thread is used for repairing. What are the main sewing threads commonly used in flame retardant and fire retardant tarpaulins? (1) Nylon thread: high breaking strength, good abrasion resistance, low hygroscopicity, high elasticity, but not enough heat resistance, generally controlled at about 120 ℃. Generally used for sewing chemical fiber fabrics, woolen wool, sweaters, etc. (2) Polyester-cotton sewing thread: Polyester sewing thread: high strength, flat and beautiful stitches, anti-wear; no mildew or rot, low price, rich colors, not easy to fade, not shrinking. (3) Nylon sewing thread: strong elongation, good elasticity, smooth texture, silky luster, excellent abrasion resistance. (4) Vinylon thread: low price, high breaking strength, lower abrasion resistance than nylon thread, and good chemical stability. (5) Silk thread: smooth surface, soft luster, good elasticity and high temperature resistance. It is used to sew woolen garments and satin fabrics; rayon has bright colors, but poor strength, poor moisture absorption, and relatively cheap price. Mostly used for machine embroidery. (6) Cotton sewing thread: good heat resistance, elasticity, abrasion resistance, moisture resistance, and antibacterial ability are poor,Suitable for high-speed sewing and durable pressing.
