1. Traditional Straw Raincoat Making Methods
Traditional straw raincoats are made from natural plant fibers, with the core material being the sedge grass (Dragon's Beard Grass), which grows in wet areas along ditches, ponds, and rivers. Preparation requires a two-step process: if the sedge is freshly picked during the dog days of summer, it should be laid out and air-dried until it is mostly dry, preserving its toughness. If the sedge is completely sun-dried, it should be sprayed with light salt water and simmered to soften it, restoring its pliability for weaving. The weaving technique utilizes a warp-and-weft interlacing method, hand-woven to form a tapered structure that covers the entire body. Special attention is paid to the sealing of the collar, cuffs, and hem to ensure rainproofing. While traditional straw raincoats offer excellent breathability, they are heavy and their waterproofing relies on the natural properties of the material. These have been gradually replaced by lighter materials.
2. Modern Raincoat Making Methods
Modern raincoats are primarily made from waterproof fabrics, commonly used materials include adhesive tape, oilcloth, plastic film, special nylon, and high-tech fabrics like Gore-Tex. The production process consists of three steps: first, the fabric is cut according to the design requirements. Common styles include two-piece, one-piece, and poncho styles. Second, the seams are treated using heat pressing or high-frequency welding to prevent water seepage. Finally, a breathable layer is added, such as the microporous structure of the Gore-Tex membrane, which repels water while simultaneously venting perspiration. Modern techniques emphasize the balance between functionality and comfort, for example, by using laser perforation to optimize breathable areas or adding details like adjustable cuffs and reflective strips to enhance practicality.
Creative Handmade Raincoat Production Methods
Creative handmade raincoats are categorized into two types: non-functional and decorative. Non-functional, such as origami raincoats, create a simple covering structure by folding waterproof cardboard or plastic sheets. These are suitable only for short-term displays or children's craft classes. Decorative, such as clay raincoat models, use ultra-light clay or pottery to shape the outline of the raincoat, paint it, and dry it as a decorative ornament. They do not provide actual rain protection. This type of production emphasizes creative expression and offers flexibility in material selection. However, they must be clearly labeled "not for wear" to avoid misleading users.
