Problems solved by technology

However, most thermochromic indicators are based on expensive inorganic color-changing materials, and because of the porous and fibrous structure of non-woven fabrics, printed inorganic indicators are also difficult to attach

Embodiment 1

[0052] The waxy material POLYWAX TM 850 (hydrocarbon wax, Baker Hughes) and black pigment PRINTEX 25 (carbon black, Evonik Degussa) were mixed at a mass ratio of 65:35 to form a colored phase change material 1 with a melting point of 100-110°C.

[0053] The colored phase change material 1 was melt-jet printed on the SMS non-woven fabric of white polypropylene at a temperature of 130°C. The size of the printed text is "No. 11".

[0054] Make a sterilization bag with the above-mentioned indicating non-woven bag, put it into a sterilizer at a temperature of 134° C., and sterilize it with pressure steam for 3.5 minutes. Then take out the package and observe the appearance of the indicator.

[0055] Such as figure 2 As shown, it can be seen that the initially clearly printed text becomes blurred and unreadable after sterilization. This indicates that the sterilization pack has been sterilized and that the nonwoven has been used.

Embodiment 2

[0057] The waxy material CERAMER TM 1608 (hydrocarbon wax grafted with maleic anhydride, Baker Hughes) and yellow pigment Permanent Yellow P-GRL06 (Permanent Yellow, Clariant) are mixed in a mass ratio of 30:70, and then dissolved in xylene solvent to form a colored phase Change material 2.

[0058] The colored phase change material 2 is printed on the polylactic acid blue SMS non-woven fabric. The size of the printed text is "No. 11".

[0059] Make a sterilization bag with the above-mentioned indicating non-woven bag, put it into a sterilizer at a temperature of 121° C., and sterilize it by pressure steam for 15 minutes. Then take out the package and observe the appearance of the indicator.

[0060] Similar to Example 1, it can be seen that the initially clearly printed characters become blurred and cannot be read after sterilization. This indicates that the sterilization pack has been sterilized and that the nonwoven has been used.

Embodiment 3

[0062] The waxy material POLYWAX TM 2000 (hydrocarbon wax, Baker Hughes) and red pigment Irgalite Red CBNL (BASF, BASF) are mixed in a mass ratio of 50:50 to form a colored phase change material 3 with a melting point of 120-130°C.

[0063] The colored phase change material 3 was melt-jet printed on polypropylene white SMS non-woven fabric at a temperature of 150°C. The size of the printed text is "No. 11".

[0064] Make a sterilization bag with the above-mentioned indicating non-woven bag, put it into a sterilizer at a temperature of 135° C., and sterilize it with pressure steam for 10 minutes. Then take out the package and observe the appearance of the indicator.

[0065] Similar to Example 1, it can be seen that the initially clearly printed characters become blurred and cannot be read after sterilization. This indicates that the sterilization pack has been sterilized and that the nonwoven has been used.

Abstract

The invention provides a steam sterilizing packaging material, a preparing method of the steam sterilizing packaging material and a method used for identifying the disposable steam sterilizing packaging material. The steam sterilizing packaging material comprises a sterilizing non-woven fabric packaging material body and a patterned colored phase change material body attached to one exposed surface of the sterilizing non-woven fabric packaging material body, the colored phase change material body is in the solid state at the normal temperature, patterns of the colored phase change material body are clear patterns before sterilizing is carried out and become blurry patterns or disappear after sterilizing is carried out, and therefore whether the steam sterilizing packaging material is used or not can be easily identified.

Description

technical field [0001] The present invention relates to a sterilization packaging material, more specifically, relates to a one-time use instruction steam sterilization packaging material. Background technique [0002] In the central supply room of the hospital, medical devices are usually packed and sterilized using sterile packaging materials to realize the reuse of these devices. Sterilization packaging materials include reusable cotton cloth and disposable crepe paper, paper-plastic packaging bags and non-woven fabrics. Among them, cotton cloth has been widely used for a long time, but after repeated use (cleaning), cotton cloth tends to appear Some small micropores or breakages lead to the failure of the antibacterial barrier. Therefore, disposable non-woven packaging materials with excellent antibacterial properties are recommended by the government and gradually accepted by hospitals. [0003] At present, the most used non-woven packaging material is polypropylene n...
