Problems solved by technology

At present, almost all manufacturers of external patches use elastic backing fabrics as industrial products of warp and weft textiles, and the quality and stability of their products are worrying.
There are multiple safety hazards in the plaster backing material of industrial warp and weft weaving: (1) The elastic fabric produced by the warp and weft weaving method has a large number of thread ends, which is very inconvenient in the production process and use of the plaster, and affects the patient's perception of the plaster. Acceptability of the plaster; (2) The surface of the cloth is not clean and prone to impurities; (3) Heavy metals exceeding the standard can easily cause the matrix of the plaster to age and lose viscosity, making its quality unstable; (4) Formaldehyde and ethylene oxide Residues, easily oxidized substances, non-volatile substances, etc. will cause strong irritation to the body or tissue; (5) The microbial content exceeds the standard, making patients prone to multiple infections, and the finished plaster produced is easily unqualified in the test

Embodiment 1

[0035] The polyester fiber elastic cloth for plaster of the present invention is made of polyester fiber (PET / PBT / PTT) as a raw material, and the following process is used for weaving and preparation;

[0036] 1 Detection of polyester fiber (PET / PBT / PTT) elastic yarn: detect polyester fiber (PET / PBT / PTT) elastic yarn, determine where PET-polyethylene terephthalate (Polythylenerephthalate), PBT - The proportion of polybutylene terephthalate (polybutyleneterephthalate) and PTT-polytrimethylene-terephthalate (polytrimethylene-tereph-thalate) meets the requirements;

[0037] II Weaving: knitting a number of qualified weft yarns (elastic yarns) to form "flat stitch" or "Ω" shape, but not limited to elastic cloth with "flat stitch" texture, and ironing;

[0038] III Impurity removal: In the 100,000-class clean area, the woven elastic fabric is pulled through two vacuum cleaners with a power of 4kw and two suction heads, both of which are equipped with upper and lower suction heads, ...

Embodiment 2

[0045] Embodiment 2, basic technique is the same as embodiment 1, but sterilization temperature is 54~58 ℃, and sterilization time is 4 hours.

[0046] The relevant indicators of the polyester fiber elastic cloth for plasters obtained in Example 2 are: elongation 150%, elastic recovery rate 77%, loss on drying 0.30%, residue on ignition 0.53%, heavy metal≤10ppm, easy oxidation, pH value , non-volatile matter are in line with relevant regulations, formaldehyde content, 0.4ppm, ethylene oxide residue 0.157ug / cm2, total number of bacteria ≤ 4, total number of mold and yeast 0, the number of Pseudomonas aeruginosa is 0. The number of Staphylococcus aureus was 0.

Embodiment 3

[0047] Embodiment 3, basic technique is the same as embodiment 1, but sterilization temperature is 30~42 ℃, and sterilization time is 12 hours.

[0048] The relevant indicators of the polyester fiber elastic cloth for plasters obtained in Example 3 are: elongation 157%, elastic recovery rate 77%, loss on drying 0.32%, residue on ignition 0.56%, heavy metal≤10ppm, easy oxidation, pH value , Non-volatile matter all meet the relevant regulations, the formaldehyde content is 0.6ppm, the residual ethylene oxide is 0.159ug / cm2, the total number of bacteria is 10, the total number of mold and yeast is 0, and the number of Pseudomonas aeruginosa is 0. The number of Staphylococcus aureus was 0.

Abstract

The invention relates to a method for weaving and processing polyester fiber elastic fabric of emplastrum. The method comprises the steps of obtaining the polyester fiber elastic fabric for the emplastrum through a weaving process and carrying out physical and chemical treatment on the polyester fiber elastic fabric for the emplastrum. The method is characterized in that the weaving and physical and chemical treatment processes of the polyester fiber elastic fabric for the emplastrum comprise the following steps of (1) detecting polyester fiber (PET / PBT / PTT) stretch yarn; (2) forming elastic fabric in plain stitch lines by a plurality of single weft yarn ( the stretch yarn) in a weaving way and stamping; (3) removing impurity; (4) carrying out high-temperature reshaping; (5) carrying out lamp detection; (6) carrying out vacuum inner packing; (7) carrying out outer packing; (8) sterilizing. According to the method for weaving and processing the polyester fiber elastic fabric of the emplastrum, disclosed by the invention, main technical performance indexes of the polyester fiber elastic fabric for the emplastrum totally meet the requirements through the physical and chemical treatment processes.

Description

technical field [0001] The invention belongs to the field of textiles and transdermal preparations, and in particular relates to a weaving method of polyester fiber elastic cloth for plaster backing and a processing method thereof. Background technique [0002] From the prediction and judgment of the International Packaging Association on my country's pharmaceutical packaging and the comprehensive analysis of the development of the current pharmaceutical market, the next few years will be the golden stage of the development of pharmaceutical packaging, so how to seize this opportunity is worth thinking about for Chinese pharmaceutical packaging companies. First of all, it is necessary to increase the company's own research and development capabilities and investment to improve the grade of packaging products. With the rapid development of my country's pharmaceutical industry, the development of national medicine, traditional Chinese medicine and innovative medicine will be l...
