Problems solved by technology

The selection of this backing material brings the following disadvantages: 1) general textiles contain certain moisture, heavy metals or harmful elements (copper, manganese, cobalt), and the existence of these components will have a series of occurrences with the matrix material in the traditional Chinese medicine plaster. The chemical changes of the matrix change the physical properties of the matrix, and the drug loses its viscosity and the matrix falls off gradually. At the same time, it affects the release and absorption of the drug ingredients contained in the matrix, making it difficult to ensure the stability of the preparation; 2) the presence of heavy metals or harmful elements, There are considerable safety hazards in the traditional Chinese medicine plaster prepared from it; 3) general textiles have not been cleaned and sterilized, and their packaging methods are difficult to ensure their cleanliness, so a large number of microorganisms are attached to the surface of the textiles, of which Including Staphylococcus aureus and Pseudomonas aeruginosa, which can cause skin infections, suppuration, and sepsis, the safety of traditional Chinese medicine plasters made from them cannot be guaranteed

Embodiment 1

[0034] Medicinal interlining cloth of the present invention is to use common chemical fiber textile forming greige cloth as raw material, adopts following process to prepare,

[0035] a, gray cloth selection: select the forming gray cloth whose physical properties such as width and tensile properties meet the preparation requirements of traditional Chinese medicine plaster (width 100cm, breaking strength radial ≥ 700N, weft ≥ 300N; elongation at break radial ≥ 40%, weft ≥ 50%);

[0036] b. Pickling: Pass the formed gray cloth through a pool with an ultrasonic device through the traction equipment. The pool is filled with 1% nitric acid solution; the travel time of the formed gray cloth in the pool is controlled to 10min; the ultrasonic frequency is 40KHz; each processing 1000m formed gray cloth pool Replace the internal nitric acid solution;

[0037] c. Water washing: the forming gray cloth after the pickling step is sprayed with clear water through the traction device throug...

Embodiment 2

[0047] Example 2, the basic process is the same as in Example 1, but with ordinary pure cotton textile forming gray cloth as raw material, the sterilization step is microwave sterilization, the microwave frequency is 2450MHz, and the residence time of the forming gray cloth in the sterilization channel is 30 Second. After treatment, the moisture of medicinal interlining cloth is 0.14%; copper is 1ppm, manganese is not detected, and cobalt is not detected; the number of bacteria, mold and yeast are all ≤10cfu / 10cm 2 ; Staphylococcus aureus and Pseudomonas aeruginosa were not detected)

Embodiment 3

[0048] Embodiment 3, basic technique is the same as embodiment 1, but ultraviolet wavelength 200nm, ultraviolet intensity 90Uw / cm 2 , the ozone concentration is 0.05g / L, the humidity in the sterilization tunnel is controlled at 60%, the temperature is controlled at 20°C, and the residence time of the formed gray cloth in the sterilization tunnel is 40min. (After treatment, the moisture content of medicinal interlining cloth is 0.22%; copper is 3ppm, manganese is 2ppm, and cobalt is not detected; the number of bacteria, mold and yeast are all ≤10cfu / 10cm 2 ; Staphylococcus aureus and Pseudomonas aeruginosa were not detected)

Abstract

The invention relates to a medicinal lining cloth and processing method thereof. The processing method includes the following technological steps: gray cloth detection, acid pickling, washing, alcohol leaching, stoving, high temperature reshaping, sterilizing and rolling up and packaging. The moisture content of the medicinal lining cloth is less than or equal to 0.5%; the content of one or multiple elements of copper, manganese and cobalt is less than or equal to 10ppm; the quantity of the contained bacteria is less than or equal to 100cfu / 10cm2; the quantity of the contained mould and yeast is less than or equal to 100cfu / 10cm2; and the quantity of staphylococcus aureus and pseudomonas aeruginosa is zero. The invention has the beneficial effects that: (1) adhesion failure and matrix dropping which are caused by ageing effect of the metal elements in paste to paste matrix can be avoided, stability of paste is good; (2) adhesion failure caused by moisture in the paste can be avoided, thus the stability of the paste is good; (3) skin infection caused by residue of pathogenic bacteria in the paste can be avoided, thus the safety of the past is higher; (4) processing is simple.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a medicinal interlining cloth applied to the backing material of traditional Chinese medicine plasters and a processing method thereof. Background technique [0002] Traditional Chinese medicine plaster is a relatively traditional traditional Chinese medicine preparation, which consists of a backing material, a drug matrix and a covering material. So far, in its preparation process, general textiles are selected as the backing material. The selection of this backing material brings the following disadvantages: 1) general textiles contain certain moisture, heavy metals or harmful elements (copper, manganese, cobalt), and the existence of these components will have a series of occurrences with the matrix material in the traditional Chinese medicine plaster. The chemical changes of the matrix change the physical properties of the matrix, and the drug loses its viscosit...
