Preparation method of breathable easy-to-tear elastic bandage cloth

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...

[0039] A kind of preparation method of air-permeable easy-tear elastic bandage cloth, the steps are as follows:

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

[0041] Extrude the bright PET melt with an intrinsic viscosity of 0.6dL / g from the three-lobed spinneret hole on the spinneret and cool it with a ring blower. According to the POY process, POY yarns are produced, and polyester yarns are obtained by air deformation. Optical profiled wire;
