Description

Waistband for safety belt and preparation method and application thereof Technical Field The invention relates to the technical field of safety belts, in particular to a waistband for a safety belt, and a preparation method and application thereof. Background In rock climbing, the safety belt is core equipment for guaranteeing life safety of a rock climber, and the waistband is used as a core bearing and wearing part of the safety belt, and the performance of the safety belt directly relates to the safety coefficient and the motion comfort of the rock climber. The rock climbing sports scene is complex, no matter natural rock wall rock climbing or artificial rock wall rock climbing is carried out, a rock climber needs to frequently carry out climbing, stay hanging, body position adjusting and other actions, buffer stress during accidental falling is likely to be faced, the waist is used as a human body core stress part, and the waist can bear the pulling force from a rope, the dead weight of a human body and the instantaneous impact force during falling, so that the waist belt needs to simultaneously meet the core requirements of bearing strength, pressure dispersion capacity and the like. The prior rock climbing safety belt waistband is of a high-density woven belt structure, waistline adaptation is realized through adjusting buckles, the design key points are concentrated on the improvement of bearing strength, and the optimization of pressure dispersion performance is limited. In practical application, the waistband has obvious defects that when a climber climbs or hangs for a long time, pressure is easy to concentrate in local areas such as two sides of the waist, the waist and the like, so that local blood circulation is unsmooth, discomfort such as waist soreness and numbness is caused, the action flexibility and the motion durability of the climber can be influenced when the waist is serious, and for a sudden falling scene, instantaneous impact force cannot be quickly and uniformly conducted to the whole waist and pelvis area, the concentrated pressure not only can aggravate human discomfort, but also can increase the risk of waist injury due to local stress overload. Disclosure of Invention The invention aims to overcome the defects of the prior art, and provides a waistband for a safety belt, a preparation method and application thereof, wherein two yarn ring assemblies are arranged in the waistband for the safety belt in a hot-pressing and laminating way, can be with pressure quick and evenly disperse whole waist and pelvis area, effectively promote the travelling comfort of climbing person's dress, reduced the risk of waist pressurized damage simultaneously. The invention provides a preparation method of a waistband for a safety belt, which comprises the following steps: s1, sticking a first yarn ring component and a second yarn ring component on a first temporary carrier, wherein the first yarn ring component and the second yarn ring component are arranged along a preset direction, and one end of the first yarn ring component and one end of the second yarn ring component are overlapped and intersected; the first yarn loop assembly comprises a plurality of first loop bodies which are sequentially stuck on the first temporary carrier from inside to outside, and the first loop bodies are formed by winding first fibers; the second yarn loop assembly comprises a plurality of second loop bodies which are sequentially stuck on the first temporary carrier from inside to outside, and the second loop bodies are formed by winding second fibers; S2, covering a connecting sheet at an overlapping intersection area of the first yarn coil assembly and the second yarn coil assembly, and sewing the connecting sheet, the overlapping intersection area and the first temporary carrier by using a first suture line to obtain a first body to be transferred; The first yarn ring assembly, the second yarn ring assembly and the connecting sheet form a pressure dispersion structure under the connection effect of the first suture line; S3, transferring the first yarn coil assembly, the second yarn coil assembly and the connecting sheet on the first body to be transferred to a second temporary carrier in a turnover way to obtain a second body to be transferred; S4, hot-pressing and attaching the first yarn ring component, the second yarn ring component and the connecting sheet on the second body to be transferred to a first fabric sheet to obtain an integrated body; S5, covering the first yarn ring component, the second yarn ring component and the connecting sheet on the integrated body by using a second fabric sheet, and fixedly connecting the first fabric sheet and the second fabric sheet to obtain the waistband for the safety belt. Specifically, the first temporary carrier is lining paper or non-woven fabric, the second temporary carrier is lining paper or non-woven fabric, and/or The first fabric piece is made of one or mor
