[0038] Example 1

[0039] A method for preparing breathable and easy-to-tear elastic bandage cloth, the steps are as follows:

[0040] (1) Preparation of bright polyester yarn:

[0041] After extruding the bright PET melt with an intrinsic viscosity of 0.6dL / g from the trilobal spinneret on the spinneret, it is cooled by a circular blower. The POY filament is prepared according to the POY process, and the polyester is obtained by air deformation. Light profiled wire

[0042] The ratio of the width of the three leaves of the same trilobe spinneret is 1.0:1.5:1.5, the length of the three leaves is the same, and the ratio of the length to the width of the narrowest leaf is 2.5:1. The included angle is 120°; the shapes and sizes of the three leaves of different trilobal spinnerets are the same; the spinneret is provided with a circle of equidistant trilobal spinnerets, the number is 24, and one of the three leaves The central axis of the narrowest leaf of the leaf-shaped spinneret is th...

Abstract

The invention relates to a preparation method of breathable easy-to-tear elastic bandage cloth. The preparation method comprises the following steps of extruding a bright PET melt from three-leaf-shaped spinneret orifices with three leaves of different lengths on a spinneret plate (all the three-leaf-shaped spinneret orifices are distributed in a concentric circle manner, and the narrowest leaf ofeach three-leaf-shaped spinneret orifice is randomly distributed), carrying out cooling by adopting circular air blowing, preparing POY yarns according to a POY process, and carrying out air deformation to prepare polyester bright special-shaped yarns, wherein in the parameters of the POY process, the cooling speed is 2.0-2.5 m/s, and in the parameters of the air deformation, the overfeed rate ofa deformation area is 27-32%; and then carrying out weaving by taking the polyester bright special-shaped yarns as raw materials of warp yarns and weft yarns to prepare the breathable easy-to-tear elastic bandage cloth. The preparation method of the breathable easy-to-tear elastic bandage cloth is simple and feasible, and low in cost, and the prepared bandage cloth has relatively good elasticity,easy-to-tear property and breathability.

Description

technical field [0001] The invention belongs to the technical field of medical and sanitary products, and relates to a preparation method of a breathable and easy-to-tear elastic bandage. Background technique [0002] Bandages are materials used to fix and protect surgical or injured parts. They are necessary for surgical operations. The main types are 100% cotton plain weave, wrinkle elastic bandages, spandex elastic bandages, PBT elastic bandages, cotton gauze selvedge bandages and adhesive bandages. Glue plaster bandage. [0003] Elasticity, breathability and tearability are critical for bandages. First of all, the bandage cloth needs a certain degree of elasticity, so that the joints will not be restricted in movement after use, will not shrink, will not hinder blood circulation or displace the joints; The support and fixation of bandages have been used before, so the bandages need to have good air permeability to reduce the reproduction of anaerobic bacteria, increase...
