The fragrance has the functions of soothing tension, relieving stress and stimulating excitement. As people's consumer demands become more personalized and fashionable, functional textiles with fragrance have become a hot spot for research and development.
The combination of fragrance and textiles has a long history. In ancient my country, there was a habit of sewing sachets on clothes. Since the Middle Ages, Europeans have sprayed perfume on clothes or used incense to reflect their elegant style.
In the 1980s, the emergence of microcapsule technology really opened the market for scented textiles, which were all the rage in Japan. Japan Kanebo Co., Ltd. has launched the aromatic fabrics developed by using microcapsule technology-the "Scent of Flowers" series. The "Culibi-65" aromatic fiber developed by Mitsubishi Rayon Company is a short fiber product with a core-sheath structure. With the fragrance of cypress wood, it can be used as cotton wool for bedding, pillows and mattresses, and it can also be made into aromatic non-woven fabrics.
To impart fragrance to textiles, on the one hand, aromatic substances can be added to the fibers by blending, composite spinning, etc., to prepare aromatic fibers, and then aromatic fibers are used to make fragrance textiles; on the other hand, the fabric can also be microencapsulated Aroma finishing to achieve. The fragrance is used as the core of the capsule, and the core material is isolated from the external environment to keep its properties unchanged. During the wearing process, due to external forces such as friction and heat, the fragrance inside the microcapsule is slowly released, so that the textile has a long-lasting fragrance function.
The BAYSCENT® fragrance finishing agent series products launched by Tuna Chemical, a subsidiary of Transchem Chemical, apply microcapsule technology to arrange various fragrance substances into textiles. When consumers exercise, the microcapsules rub against the body, and the effective ingredients of the fragrance are released, which can produce various pleasant flavors such as coffee, rose, jasmine, strawberry, and vanilla.
The JLSUN fragrance finishing agent developed by Jiershuang Group is a nano microcapsule fragrance extracted from aromatic plants and made by biotechnology. It can be used for fragrance finishing of cotton, wool, silk, linen, chemical fiber and other fabrics, and it is non-toxic to humans. It is harmless and will not lose its fragrance after washing with water.
In terms of actual product application, Transchem Chemical uses microcapsule finishing technology to prepare lavender scented silk scarves. The finishing agent is derived from pure plant extracts. The friction of the fabric causes the microcapsules to burst and produce fragrance. Health effect.
The British Scotch tweed manufacturer and whisky brewer jointly funded the development of a new type of "Harris Tweed" (Harris Tweed), named "Aqua Alba" by universities and colleges. This product uses microcapsule aroma finishing technology to layer the finishing agent Distributed in the fabric, so that it can emit whiskey fragrance for a long time.
In addition to the microcapsule finishing technology, researchers at the University of Minho in Portugal have modified the cotton fabric to give it a pleasant lemon scent. The first method is to fuse the protein OBP-I extracted from wild boar with CBMN1 from FIMI, and then cultivate it together with the functionalized aromatic precursor of cotton fabric, and finally make functionalized cotton fabric. The second method is to fuse the carbohydrate binding module CBMN1 with the SP-DS3 peptide, anchor the protein in liposomes containing fragrance, and then use the functionalized liposomes for the finishing of cotton fabrics. The functional cotton fabric prepared by the two methods can release citronellol (a scented substance) when it comes into contact with acidic sweat.
