Embodiment 1

[0038] A preparation method of bandage cloth, the steps are as follows:

[0039] (1) Preparation of semi-dull polyester drawn yarn:

[0040] The PTT melt with an intrinsic viscosity of 0.92dL / g and 0.2wt% titanium dioxide dispersed therein is extruded from the trilobal spinneret hole on the spinneret and cooled by ring blowing, and FDY filaments are produced according to the FDY process, and then Semi-dull polyester drawn filaments are prepared by relaxation heat treatment;

[0041]There is a circle of equidistantly distributed three-lobed spinneret holes on the spinneret plate, the number is 12, and the three leaves of the three-lobed spinneret holes are not equal in width, and the width of the narrowest lobe is 0.06mm and 0.06mm respectively. , 0.07mm, 0.08mm, 0.06mm, 0.11mm, 0.09mm, 0.06mm, 0.06mm, 0.08mm, 0.12mm, 0.12mm. The ratio is 1.0:1.0:1.1, the length of all three lobes is the same, the ratio of the length to width of the widest lobe is 2.0:1, and the angle between...

Embodiment 2

[0049] A preparation method of bandage cloth, the steps are as follows:

[0050] (1) Preparation of semi-dull polyester drawn yarn:

[0051] The PTT melt with an intrinsic viscosity of 1.05dL / g and 0.24wt% titanium dioxide dispersed therein is extruded from the trilobal spinneret holes on the spinneret and cooled by ring blowing, and FDY filaments are produced according to the FDY process, and then Semi-dull polyester drawn filaments are prepared by relaxation heat treatment;

[0052] There is a circle of equidistantly distributed three-lobed spinneret holes on the spinneret plate, the number is 12, and the three leaves of the three-lobed spinneret holes are of different widths, and the width of the narrowest leaves are 0.06mm and 0.08mm respectively. , 0.11mm, 0.06mm, 0.11mm, 0.09mm, 0.06mm, 0.06mm, 0.08mm, 0.12mm, 0.12mm, 0.11mm. The ratio is 1.0:1.0:1.5, the length of all three lobes is the same, the ratio of length to width of the widest lobe is 2.0:1, and the angle betw...

Embodiment 3

[0060] A preparation method of bandage cloth, the steps are as follows:

[0061] (1) Preparation of semi-dull polyester drawn yarn:

[0062] The PTT melt with an intrinsic viscosity of 1.04dL / g and 0.23wt% titanium dioxide dispersed therein is extruded from the trilobal spinneret hole on the spinneret and cooled by ring blowing, and FDY filaments are produced according to the FDY process, and then Semi-dull polyester drawn filaments are prepared by relaxation heat treatment;

[0063] There is a circle of equidistant trilobal spinneret holes on the spinneret plate, the number is 18, and the three leaves of the trilobal spinneret holes are of different widths, and the width of the narrowest lobe is 0.06mm and 0.08mm respectively. , 0.11mm, 0.06mm, 0.11mm, 0.09mm, 0.06mm, 0.06mm, 0.08mm, 0.12mm, 0.12mm, 0.08mm, 0.11mm, 0.06mm, 0.11mm, 0.09mm, 0.06mm, 0.07mm, the rest The width of the two leaves is fixed, and the ratio of the maximum width of the narrowest leaf to the width of t...

Abstract

The present invention relates to a kind of preparation method of bandage cloth, first the PTT melt that is dispersed with the titanium dioxide of 0.20~0.27wt% from the trilobal spinneret hole (all trilobal shaped) The spinneret holes are distributed in concentric circles, and the center line of the widest lobe of each trilobal spinneret hole passes through the center of the circle and points toward the center of the circle) After extrusion, it is cooled by ring blowing, and FDY filaments are produced according to the FDY process, and then subjected to relaxation heat treatment Prepare semi-dull polyester drawn yarn, then use 72D semi-dull polyester drawn yarn as warp raw material, use 40S combed cotton as weft raw material, warp yarn, warp and weave to make bandage cloth. The preparation method of the bandage cloth of the present invention is simple and easy to implement, and the cost is low. The bandage cloth does not have the problem of excessively tight winding when bandaging a wound, and has good air permeability.

Description

technical field [0001] The invention belongs to the technical field of medical and sanitary products, and relates to a preparation method of bandage cloth. Background technique [0002] In the process of life and medical treatment, people often need bandages. Bandages in different situations often have different requirements for bandages, such as the elasticity, comfort, and viscosity of bandages. All kinds of bandages and adhesive plasters are widely used in medical and sports fields. Existing bandages are easy to wrap too tightly due to the material and the air permeability needs to be improved. [0003] Therefore, it is of great significance to study a bandage cloth that is not easy to wrap too tightly and has better air permeability. Contents of the invention [0004] The invention provides a preparation method of a bandage cloth, aiming to solve the problems in the prior art that the bandage cloth is easily wound too tightly and has poor air permeability. [0005] ...
