Abstract

The invention belongs to the field of novel materials for textiles, particularly relates to a manufacturing method of a non-woven jointless annular elastic bandage. The manufacturing method includes steps of 1), according to weight, feeding 59.8-90% of polyolefin elastomer, 5-40% of silicone rubber, 0.1-5% of radiation sensitizer and 0.1-0.5% of antioxidant into a double-screw extruder and extruding and pelleting to obtain polyolefin mixed master batch; 2), feeding the polyolefin mixed master batch into a hopper of a melt spinning machine, jetting out by a spinning jet, cooling through a side-blowing passage, winding on a roll to obtain a primary bandage by a winding device; 3), feeding the primary bandage into a hot rolling machine to be hot-rolled; 4), disposing the hot-rolled primary bandage in an irradiation environment, irradiating under certain irradiation dose to obtain the non-woven jointless annular elastic bandage. The non-woven jointless annular elastic bandage has the advantages of direct forming, no joints and lasting elasticity.

Description

technical field [0001] The invention belongs to the field of new textile materials, in particular to a method for preparing a non-woven jointless annular elastic bandage. Background technique [0002] Bandages are usually elastic tubular fabrics that support and protect the joints they are worn on, such as knee or elbow pads during sports or ankle bandages that act in a protective or supportive manner. There are generally two types of traditional elastic bandages. One is the loom fabric obtained from elastic fibers, which is shaped into the shape of the protected limb through special sewing techniques; the other is directly formed into the shape of the protected limb by knitting technology. shaped bandage. The common feature of these two types is that they will loosen or deform after a long time, and they will not play a good protective role. The addition of elastic fibers will affect and woven bandages will have uneven stress due to stitching problems, which will affect t...
