1. Characteristics and Development Trends of Medicinal Fabrics
(1) Characteristics of Medicinal Fabrics
Medicinal fabrics refer to fiber fabrics with medicinal functions, which combine drugs with fabrics and clothing. , during the wearing process, through respiration and skin absorption, the drug ingredients enter the human body and produce medical and health care effects. Therefore, pharmaceutical fabrics can also be regarded as a new type of pharmaceutical textiles. Since drug fabrics directly combine drugs with fabric clothing, this provides the possibility and convenience for local administration and external treatment of internal diseases. It can also improve the effective utilization of drugs.
Underwear, bedding, etc. are made of medicinal fabrics, which can be used to apply medicine to a large area for a long time. Conducive to disease treatment.
(2) Development Trend of Medicinal Fabrics
People’s consumption of textiles has gone far beyond keeping warm. On the premise of being beautiful, they are moving towards the goals of comfort and health. Medicinal fabrics can just meet the requirements of comfort and health. Currently, more and more varieties of pharmaceutical fabrics are being developed. From clothing (such as underwear, pajamas, pantyhose, etc.) to handkerchiefs, towels, sheets, quilts, mattress wadding and pharmaceutical non-woven fabrics, etc. The variety covers a wide range of areas. Judging from the market situation of pharmaceutical fabrics, its development direction has the following three trends:
(1) Expand the market. Increase the variety of medicinal fabrics. Expand its quantity and expand its application fields.
(2) Popularity. While ensuring the medicine, we also start from the fabric, style, and color of the clothing to meet its popularity, so that the product will not just become a hospital supply.
(3) Functional compounding. It is not only limited to a certain drug function, but while exerting its drug function, it can also be combined with other functions, such as heat preservation, UV protection, etc.
2. Classification of medicated fabrics
Medicinal textiles can be divided into the following three types according to the different drugs used:
(1) Traditional Chinese medicine fabrics
Add the extracted ingredients of traditional Chinese medicine directly to the finishing agent , or use microcapsule technology to contain the active ingredients of traditional Chinese medicine for coating, or use dyeing technology to combine the active ingredients of traditional Chinese medicine into the fibers of the fabric. The fabric has certain medicinal properties.
(2) Western medicine fabrics
Crush Western medicine into fine powder, directly mix it into the spinning solution, and perform blending spinning, or use microcapsule coating method, or graft certain drug groups to the fiber Or use modified dipping method to produce western medicine fabrics.
(3) Aromatic fabrics
Because natural aromatic substances have medical effects such as refreshing, sedating, anti-migraine, suppressing appetite or promoting appetite, they can have psychological and physiological health care effects on people. Its therapeutic effect is first to adjust the function of the nervous system and influence human brain consciousness, and secondly, the aroma enters the blood circulation and promotes cell metabolism through its pharmacological effects.
3. Pharmaceutical fabric design
(1) Fabric tissue specification design
1. Raw material design According to different uses, natural fibers, man-made fibers and synthetic fibers can be used.
2. Yarn design Yarn can be single yarn or stranded yarn. The twist is similar to regular fabrics. The yarn used in the fabric can be pure yarn or blended yarn.
3. Fabric density design The warp and weft density of the fabric can be determined according to the characteristics of the yarn used and the purpose of the fabric. The design approach is similar to regular fabrics.
4. Fabric weave design Depending on the purpose of the fabric, the selected fabric weave is also different. For underwear, choose a simple weave; for sheets, you can use a combined weave; for pajamas, you can use a changing weave or a towel weave, etc.
(2) Design of combination method of drugs and fabrics
1. Processing of drug fibers
(1) Post-finishing method. Almost all pharmaceutical finishing techniques used on fabrics can be used on fibers and yarns. However, during the textile process, the fiber coating is often damaged and the drug properties are lost. Therefore, this method has great limitations.
(2) Blended spinning method. The drugs and aromatics are evenly mixed into the spinning liquid for spinning without changing the traditional spinning equipment. Fiber base materials often use polyester, polyamide, etc.
(3) Core-sheath spinning method. This method directly uses the core-sheath composite technology that emerged in the 1980s. The sheath uses polyester, polyamide and other fiber materials to maintain fiber properties. Drug substances are added to the core material. In order to prevent the loss of the drug during spinning, the core material is often made of polyethylene copolymer or homopolymer with a particularly low melting point and hydrolysis resistance. The drug escapes along the longitudinal direction of the fiber and exerts its medicinal properties. effect. Varieties produced by this method include hollow core-clad types (the core containing aromatic substances is made into a hollow structure, which can enhance the concentration of drugs escaping from both ends) and hollow multi-core core-clad types (the hollow structure is made of multiple cores). material and outer sheath).
(4) Modified impregnation method. Select a certain oil-absorbing polymer to be blended and spun into conventional chemical fibers to modify them, and then immersed in oil-based fragrances and kept under pressure or normal pressure for a certain period of time. The oil-absorbing polymers can absorb enough fragrances and Gives the fibers aromatic properties.
2. Finishing technology of pharmaceutical fabrics
(2) General coating and dipping method. Soak the fabric in the finishing liquid, which contains pharmaceutical preparations, adhesives, etc.; you can also add microporous powders such as calcium carbonate to absorb drugs to coat the fabric; you can also add drugs to the printing and dyeing slurry to coat the fabric. Fabric printing, etc. The fabrics produced by this method have poor durability of medicinal properties.
