The number of folds of the umbrella. The folding number of the umbrella can be divided into a straight rod (one fold), two folds, three folds umbrella , and five folds. To some extent, the more the number of folds of the umbrella, the more convenient the carrying. Straight rod is our most traditional form. Oil paper umbrella and tarpaulin umbrella are the representatives of straight rod. The umbrella of this type of umbrella is generally very durable, not only can be used as an old man's crutches, but also as a defense tool if necessary. And art umbrellas are generally straight umbrellas. The most impressed in the umbrella is the European-style umbrella. The 17th-century British lady umbrella (佰nas umbrella) is the representative of the two-fold umbrella. It is more decorative, looks gorgeous, diverse in style, more artistic and not practical. Generally used only for sunshade. Three folding umbrella is the most popular and most commonly used. For example, most of the rain and rain are three-fold. It is small in size, easy to carry, and practical. It is very popular among people. Because it folds up really like a pencil, only a few centimeters away, it can be carried in a pocket, which is lighter than the tri-fold, and this type of umbrella is very popular today.
There are three main types of fabrics commonly used in umbrellas. The cost from low to high is: polyester, PG cloth, nylon. The characteristics of the polyester cloth are: the color is more beautiful, and the umbrella fabric is placed on the hand, the crease is obvious, and it is not easy to restore. When the fabric is moving, it will feel resistance, and when it is smashing, there will be a rustling sound. Applying a layer of silver glue on the polyester is what we usually call a silver plastic umbrella. The function of the silver tape to protect against ultraviolet rays is better, but after a long time of use, the silver glue in the folded place is easily separated. Applying a layer of silver powder on the polyester is what we usually call a pearl cloth umbrella. The color of the pearl cloth is more beautiful, which is very popular among women, but the anti-sun UV effect is not ideal. The PG cloth is also called a spray cloth, and the high density impact cloth is a new type of cloth. PG has the following characteristics: the color is matte and dark. The fabric feels like cotton, the light resistance is better, the cost of PG cloth is relatively high, but the UV protection function, the quality stability, the color grade are ideal, it is a better umbrella cloth, and the general PG cloth is only used in high-grade In the umbrella. Nylon cloth is also a high-grade variety of umbrella fabrics. This poncho has a bright color and feels like silk on the hand. It is moved back and forth with hand, and the resistance is very small. However, this kind of cloth has a weakness, which is greatly affected by the humidity of the air, and the umbrella cloth shrinks more seriously, sometimes even affecting the normal opening and closing of the umbrella surface. Therefore, in our commonly used umbrella fabrics, it is not particularly large.
