Problems solved by technology

But the density of nylon fiber is 1.14g / cm 3 , the density of water is 1.0g / cm 3 Large, leading to the nylon climbing rope with excellent performance will sink to the bottom of the water. In addition, the nylon molecular chain contains hydrophilic amide bonds, which makes the climbing rope made of nylon braided more hydrophilic. When used in harsh environments, it will make the The weight of nylon climbing rope increases, which brings inconvenience to users

Abstract

The invention relates to a preparation technology of a waterproof climbing rope, and belongs to the field of rope preparation. The preparation technology of the waterproof climbing rope comprises pretreatment, water and oil repellent treatment, waterproof heat treatment, weaving and product forming, wherein a fluoride-containing compound type water and oil repellent finishing agent is adopted for the water and oil repellent treatment. The fluoride-containing compound type water and oil repellent finishing agent is added to the climbing rope and combined with waterproof heat treatment and weaving, an effective waterproof protection layer is formed on the surface of the climbing rope, water cannot permeate into the climbing rope, so that the climbing rope floats on the water surface and does not sink to the water bottom, and the practicability is improved greatly. Further, by means of the added fluoride-containing compound type water and oil repellent auxiliary, the climbing rope is not likely to absorb water, the traditional phenomenon of weight increase after water absorption is avoided, and the climbing rope is more convenient to use for a user and has quite bright market prospects and very high economic benefits.

Description

technical field [0001] The invention relates to a preparation process of a waterproof mountaineering rope, which belongs to the field of rope preparation. Background technique [0002] Climbing ropes are the most important equipment in mountaineering both in history and today. Various climbing techniques such as ascent, descent and protection are all centered on climbing ropes. Many mountaineering supplies such as iron locks and safety belts can only be used when they are connected with mountaineering ropes. Early mountaineering ropes were made of cotton, and then developed to use hemp. After the 1950s, they were changed to nylon fibers with excellent performance in many aspects such as tension, durability, and abrasion resistance. But the density of nylon fiber is 1.14g / cm 3 , the density of water is 1.0g / cm 3 Large, leading to the nylon climbing rope with excellent performance will sink to the bottom of the water. In addition, the nylon molecular chain contains a hydro...
