A climbing device (4) comprising a wall fixing mechanism (8), comprising at least one movable end (12), from a closing configuration to an opening configuration, adapted to be inserted into a crack or a hole in said closing configuration and to interlock in said crack or hole in said opening configuration, a main body (16) provided with a drive mechanism (20) operatively connected to said at least one movable end (12), so as to allow the shifting from the closing configuration to the opening configuration, and also with a coupling ring (24), arranged opposite to the at least one movable end (12) with respect to the drive mechanism (20), - wherein a flexible strap (28) is arranged inside said coupling ring (24). The flexible strap (28) comprises at least one piece of inner wire (32) extending from a first inner end (36) to a second inner end (40), repeatedly wound so as to form a plurality of overlapping rings (44), said first inner end (36) and second inner end (40) being joined together at an inner junction point (48), an outer tubular sock (52), wrapping said overlapping rings (44) and extending from a first outer end (56) to a second outer end (60). The first outer end (56) and the second outer end (60) are coupled to each other at an outer junction point (64).

This application relates to a stitch structure and sewing method for splicing multiple pieces of warp-knitted metal mesh, and pertains to the field of application technology of medium and large-sized metal mesh for satellite antenna reflector surfaces. The method for splicing and sewing warp-knitted metal mesh includes: S1, providing at least two pieces of warp-knitted metal mesh to be spliced; S2, overlapping the edges of adjacent pieces of mesh with a width of 1-1.5cm to form an overlap area; S3, using polyimide or aramid filaments with a specification of 200-600D as sewing thread, and sewing along the overlap area using sewing equipment, wherein the stitch spacing is 0.8-1.2cm and the stitch density is 3-5 stitches / cm. This application improves surface accuracy by using an overlap width of 1-1.5cm and automated parameter control for sewing, a stitch length of 0.8-1.2cm, a density of 3-5 stitches / cm, and high-performance polyimide or aramid thread of 200-600D. This effectively avoids the problems of easy aging and embrittlement of traditional polyester thread or webbing, and improves long-term stability.

The utility model relates to a kind of joint structure of textile drying net, including drying net first end and drying net second end, drying net first end is woven by first end head warp and first end head weft, drying net second end is woven by second end head warp and second end head weft, first end head warp exceeds first end head weft and forms first end head warp connecting section, second end head warp exceeds second end head weft and forms second end head warp connecting section, first end head warp connecting section and second end head warp connecting section are overlapped together and form warp joint section, warp joint section is woven together with joint section weft and constitutes drying net joint part, the surface of drying net joint part is equipped with drying net joint part adhesive layer. The utility model has the advantages of good flatness and reliable connection, solves the problem of poor flatness and poor reliability of existing joint.

The invention relates to a method for manufacturing a surface, equipment, or skin decontamination wipe that may be contaminated by a toxic product in liquid form, comprising the steps of: - arranging fibers comprising more than 98% polypropylene in a continuous non-woven buffer layer, said fibers being continuous, - sandwiching the buffer layer between a first transfer veil and a second transfer veil, identical to the first transfer veil, each non-woven transfer veil comprising continuous fibers, said fibers comprising at least 60% polypropylene, and being configured to transfer the liquid toxic product from outside said transfer veil to the buffer by capillary action, - heat-sealing the first transfer veil, the buffer layer, and the second transfer veil, according to a predefined wipe shape, and - cutting said wipe.
