Problems solved by technology

[0003] The reported sterilization packaging materials mainly include: textile materials (such as: cotton cloth, non-woven fabrics, etc.), airtight hard sterilization boxes, crepe wrapping paper, etc. Among them, the airtight hard sterilization boxes need to be imported from abroad. The cost is too high, and the physical resistance of crepe wrapping paper is poor, easy to tear and puncture, both of which are not recognized by domestic hospitals and are rarely used
[0004] For sterilized packaging materials, textile materials are currently the most widely used in d

Example Embodiment

[0041] Example 1

[0042] Process such as figure 1 shown:

[0043] (1) Spinning and weaving to obtain grey fabric (including 65% polyester, 35% cotton), TC 21s×21s, 108×58 (“TC” means polyester cotton; “21s×21s” means yarn count: 21s in warp direction , 21s in the weft direction; "108×58" indicates the density: 108 pieces / inch in the warp direction, 58 pieces / inch in the weft direction);

[0044] (2) dyeing the grey cloth to obtain dyed cloth;

[0045] (3) adopt the mixed solution of following formula to carry out waterproof cross-linking treatment to dyeing cloth;

[0046] Waterproofing agent C6 (AG-E061): 100g / L, cross-linking agent (end-blocked sodium isocyanate, MEIKANTE FM-1): 30g / L, the solvent is water, and the pH value is adjusted to 5-6 with acetic acid;

[0047] Adopt padding method, speed: 30m / min;

[0048] (4) Calendering;

[0049] (5) Coating:

[0050] Equipment: Floating knife scraping coating

[0051] Speed: 20~25m / min;

[0052] Curing temperature: 150℃...

Example Embodiment

[0057] Example 2

[0058] In step (5), the mixed solution A is diluted (1 part of mixed solution A+1 part of water, i.e.: the concentration of polyurethane coating in mixed solution A is diluted from "100g / L" to "50g / L") as a coating The other process steps and process conditions are the same as in Example 1, and the finished product C-II is obtained.

Example Embodiment

[0059] Example 3

[0060] In step (5), the mixed solution A is diluted (1 part of mixed solution A+3 parts of water, namely: the concentration of polyurethane paint in mixed solution A is diluted from "100g / L" to "25g / L") as coating The other process steps and process conditions are the same as in Example 1, and the finished product C-III is obtained.

Abstract

The invention discloses a terminal sterilization medical instrument textile packaging material production method. The production method includes the steps: a, taking fabrics; b, performing water repellent treatment for the fabrics by the aid of mixed liquid I; c, calendaring the fabrics after water repellent treatment; d, coating the calendered fabrics with mixed liquid II; e, cleaning the coated fabrics to obtain textile materials. The waterproof level, hydrostatic pressure and air permeability of a finished product prepared by the production method can meet requirements, the finished product is suitable for serving as a terminal sterilization medical instrument textile packaging material and has good wash resistance, reusability of the material is greatly improved, cost is effectively reduced, and the finished product can be widely accepted by hospitals.

Description

technical field [0001] The invention relates to a production method of a textile packaging material for terminally sterilized medical devices (note: hereinafter referred to as textile material), and the application of the product as a package for terminally sterilized medical devices. Background technique [0002] Sterilization packaging materials are necessary consumables for hospitals, mainly used for packaging of clinical diagnostic equipment before sterilization. The purpose is to prevent the sterilized equipment from being recontaminated by bacteria in the environment during the process of aseptic storage and aseptic transfer. , remain sterile until opened for use. [0003] The reported sterilization packaging materials mainly include: textile materials (such as: cotton cloth, non-woven fabrics, etc.), airtight hard sterilization boxes, crepe wrapping paper, etc. Among them, the airtight hard sterilization boxes need to be imported from abroad. The cost is too high, an...
