Polypropylene is the trade name of polypropylene fiber. It is a fiber made from propylene as a raw material through polymerization and melt spinning. Polypropylene officially began industrial production in 1957 and is a rising star among synthetic fibers. Because polypropylene fiber has the advantages of simple production process, low product price, high strength, and light relative density, polypropylene fiber has developed rapidly. At present, polypropylene is the fourth largest variety of synthetic fibers. The production of polypropylene fiber includes short fibers, filaments and split film fibers. Polypropylene film fiber is made by first making polypropylene into a film, and then stretching the film to split it into a network of fibrils. Polypropylene is widely used in the manufacture of industrial fabrics and non-woven fabrics. Such as carpets, industrial filter cloths, ropes, fishing nets, building reinforcements, oil-absorbing blankets and decorative cloths. For civilian use, polypropylene can be spun purely or blended with wool, cotton or viscose to make various clothing materials. In addition, polypropylene film fibers can be used as packaging materials. The main physical and chemical properties of polypropylene 1. Form The longitudinal surface of polypropylene is straight and smooth, and the cross section is round. 2. Density The biggest advantage of polypropylene fiber is its light texture. Its density is only 0.91g/cm3, which is the lightest variety among common chemical fibers. Therefore, polypropylene fiber of the same weight can obtain a higher coverage area than other fibers. 3. Strength and elongation Polypropylene has high strength, large elongation, high initial modulus and excellent elasticity. Therefore, polypropylene fiber has good abrasion resistance. In addition, the wet strength of polypropylene is basically equal to the dry strength, so it is an ideal material for making fishing nets and cables. 4. Hygroscopicity and dyeability Polypropylene has very little hygroscopicity, almost no moisture absorption, and the moisture regain rate under general atmospheric conditions is close to zero. But it has a wicking effect and can transmit water vapor through the capillary in the fabric, but it does not have any absorption effect. Polypropylene fiber has poor dyeability and incomplete chromatograms, but the coloring of the original solution can be used to make up for the shortcomings.

The difference between seat belts and safety ropes
seat belt: The safety belt is a protective equipment used to protect against falling. The conditions of use are distinguished. The general types are as follows: 1. Safety belts for surrounding poles: This type of safety belts mainly rely on tightly surrounding a fixed structure, or fixing the human body to the structure, so that the operator can be protected while also being able to use both hands to perform other tasks. Work operations. 2. Area restriction seat belt: This type of seat belt mainly restricts the area of ​​activity of safety workers, thereby reducing or avoiding safety accidents of safety workers falling. 3. Falling suspension safety belt: during high-altitude operations, when a safety worker falls accidentally, it is a device to hang the safety worker. safety rope: A rope made of synthetic fibers, usually used to connect safety belts. The function of the safety rope is mainly dual protection to ensure the safety of safety workers. Common safety ropes are usually 2 meters, and some are 2.5 meters, 3 meters, 5 meters, 10 meters and 15 meters. Generally, safety ropes with a length of more than 5 meters are used as slings and are commonly used. The categories are as follows: 1. Parallel safety rope: bind the safety rope to the steel frame to perform horizontal movement and safe operation. This method of use has a lower elongation rate, but a higher slip rate. Dragging usually uses steel wire injection molding to facilitate the safety hook to move freely on the rope. This method of use is commonly used in the installation of steel frames in thermal power generation projects, as well as the installation and maintenance of steel structures. 2. Vertical safety rope: This method of use must be used with a climbing self-locking device. It can be braided or twisted, as long as the tensile strength specified by the country is met, and it is mainly used for vertical movement up and down. 3. Fire safety rope: It is mainly used for escape from high-rise buildings. There are two kinds of weaving and twisting. It must be strong and light, and it must have a buckle and a safety lock. The tensile strength must meet the national standard. It is widely used in Residents of modern high-rise residential buildings and high-rise buildings. 4. Exterior wall cleaning rope: divided into main rope and auxiliary rope. The main rope is used to hang and clean the seat board. The auxiliary rope is also the auxiliary rope to avoid accidental fall. The diameter of the main rope is 18mm-20mm. The rope is required to be strong and not loose. Twist, high tensile strength. The diameter of the secondary rope is 14mm-18mm, the standard is the same as other safety rope standards.

Safety rope storage method
In order to ensure safety, it must not be used in high temperature, and the rope must not be knotted. The visual inspection should be done each time it is used, and the use should be stopped immediately when it is found to be damaged; Strictly install in accordance with the requirements of the standard. When used in conjunction with other equipment, it should be installed under the guidance of the certificate holder. The selection of the rope should match the actual pulling force requirements. The special equipment should be selected for fixing, and the installation should not be hasty; When using the rope for the first time, lay down the rope, pass it into the rope release device from the middle hole, and roll it apart. Do not release the safety rope in a disc type; The safety rope should be subjected to a load test before being reused, and it can be used only after passing the inspection, and it should be discarded if any abnormality is found;

How to use safety rope
Rope function: Rope is a protective equipment to prevent falling of workers at heights. Because the greater the height of the fall, the greater the impact it receives. Therefore, the rope must have the following two basic conditions: (1) It must have sufficient strength to withstand the impact of the human body when it falls; (2) It can prevent the human body from falling. To a certain limit that can cause injury (that is, it should be able to pick up a good human body before this limit, and no longer fall down). This condition needs to be explained again. When the human body falls from a high place, if it exceeds a certain limit, even if the person is pulled with a rope, the impact force will be too large, and the internal organs will be injured and death. For this reason, the length of the rope should not be too long, and there must be a certain limit.

Introduce two safety net impact tests
Impact resistance test method: simulated humanoid sand bag; length 100cm, bottom area 2800 cm2, mass 100kg±2kg, test frame opening size is consistent with the test net specifications, height is above 1.5m, it should be able to raise, lower and release simulated humanoid sand package. The carbon tool steel pipe used for the frame material should have sufficient rigidity, but the plane of the test frame is parallel to the horizontal plane. Hang the human-shaped sand bag so that the center of the sand bag is at the center of the frame and the long side is parallel to the long side of the dense mesh net and lift it to the top of the frame, then the test net is firmly tied to the test frame, and then the sand bag is lifted to its bottom After 1.5m from the net surface, release the sand bag. According to the impact of the dense mesh net, the net body is broken or penetrated, the length of the net body is broken, the edge and the tether are broken, etc. to indicate the breakage.
