With the development of society, products are constantly updated, and the umbrella industry is no exception. Today we will focus on the fibrous ribs.
Since the 1960s and 1970s, most of the umbrella frames we have used are made of iron and steel frames, and the high-end ones are useful for aluminum umbrella frames. The characteristic of steel bone is that it is easy to embroider. Although aluminum bone is light but easy to break, it is not strong enough and durable.
With the continuous upgrading of products, more and more umbrella frames now use glass fiber, which is what we are going to talk about today. Compared with the steel frame, the umbrella frame made of glass fiber has the characteristics of no rust, high temperature resistance, wind resistance and rainstorm resistance, and the umbrella frame made is not easy to break. Durable.
The fiberglass yarn, the raw material of the fiber umbrella rib, determines the quality of the umbrella rib, and glass fiber yarn has low, medium, and high-end quality.
There are three grades of fiber yarn: soil yarn, high alkali yarn and medium alkali yarn.
Earth yarn: The umbrella skeleton made of this material is low-grade, and the umbrella bone fiber is easy to break. Many unscrupulous merchants cut corners by buying earthen yarn to make it shoddy, using the unrecognizable layman to make huge profits. After using this kind of umbrella, you will find that the ribs are easily broken and cracked.
High-alkali yarn: The umbrella ribs are strong, elastic and tough, and will not crack, and can pass the non-toxic test and compression test. Umbrella skeletons for high-end umbrellas are usually produced from this high-alkali yarn.
Medium alkali yarn: The characteristic will be relatively soft, suitable for short umbrella accessories.
According to the size of the umbrella, the thickness of the fiber used is different: the conventional thickness of fibrous bone is 6.0MM 5.0MM, 4.5MM, 4.2M, 4.0MM, 3.5MM, 3.2MM, 3.0MM, 2.8MM, 2.5MM, 2.0MM, etc. And so on, the cost of coarse is generally higher than that of fine. This is why it is also a full-fiber umbrella rib, and the price is high or low. The thicker fibrous bone will cost more, use more materials, and the rib is heavier and relatively strong. When customers buy fiber umbrellas, they should also pay attention to the thickness of the fiber bones. And the quality, the fibrous bone surface is usually better if it is brighter.
Yukang Umbrella Factory uses high-alkali yarns to produce fiber umbrella ribs. The fiber bones used in golf umbrellas are 5.0MM/4.0MM fibers. 100% of them have passed the Japanese quality test requirements. They have reached the level of firmness, reliability, wind resistance, and toughness. International standards.
Fibrous bone can be made into white, black, red, yellow, orange, purple and other colors. Can meet the different needs of guests.
