Price trendTake the rutile-type titanium dioxide of sulfuric acid method, which has a relatively large volume of goods in the domestic market, for example. According to the data of the business community, the price of titanium dioxide is stable this week, with an average price of 15,433.33 RMB/ton.Analysis review Product: Since April, the main domestic titanium dioxide has remained stable. Affected by the epidemic situation abroad, some production enterprises have restricted production and the market price has weakened. This week, the price of titanium dioxide is mainly stable. The current domestic ex-factory price of rutile titanium dioxide is 14,000-16,300 RMB/ton, the ex-factory price of anatase titanium dioxide is 12,500-13,000 RMB/ton, and the price of chlorinated titanium dioxide In 18,500-21,000 RMB/ton. As far as the current international situation is concerned, the titanium dioxide market as a whole is weak.Industrial chain: The price of titanium ore market in Panxi region was...

Functional fibers are dietary fibers with additional health benefits beyond basic nutritional functions. Unlike traditional fibers, which primarily enhance digestion and prevent constipation, functional fibers may also contribute to managing blood sugar levels, reducing cholesterol, aiding in weight management, and possibly preventing certain diseases. These fibers can be naturally occurring in foods or added during processing and include varieties like inulin, beta-glucans, resistant starch, and oligosaccharides. They play a crucial role in a balanced diet, promoting gut health through the support of beneficial gut flora and even potentially reducing the risk of colon cancer. The integration of functional fibers into one’s diet should be considered part of a comprehensive approach to maintaining overall health.

Q viscosity of polyester resin

The viscosity of polyester resin varies depending on its type (orthophthalic, isophthalic, dicyclopentadiene (DCPD)) and formulation specifics. Typically, its viscosity ranges from 200 to 600 centipoises at room temperature. Key factors influencing viscosity include the resin’s molecular weight, the amount and type of styrene monomer used, and any added fillers or reinforcements. Lower molecular weight or higher styrene content can decrease viscosity, making the resin more fluid. Conversely, fillers or higher molecular weight increase viscosity. Adjusting viscosity is crucial in applications like fiber-reinforced plastics, where resin must impregnate fibrous reinforcements effectively. Manufacturers might modify resin formulations to target specific viscosities for different processes or applications, such as hand lay-up, spray-up, or resin transfer molding.

Q is nylon or polyester cooler

When considering whether nylon or polyester is warmer, it’s key to understand how these synthetic fibers trap air and manage moisture – both crucial factors in thermal insulation. Nylon, known for its softness and flexibility, also possesses good insulative properties, largely due to its ability to absorb a small amount of water while remaining felt dry to the touch, potentially providing a slightly warmer feel in damp conditions. On the other hand, polyester is more hydrophobic, meaning it repels water more effectively and dries rapidly, but it’s also slightly less breathable. In terms of warmth, polyester’s structure allows it to trap air more efficiently, and it is often preferred for thermal insulation in outdoor clothing and gear. Additionally, polyester fibers can be engineered to have a hollow core, enhancing their insulating properties by trapping more air, which is a key determinant of a material’s warmth. Thus, while both materials have their uni...

Q is it ok to wear polyester

Steaming polyester is generally safe, but caution is needed. Polyester, a synthetic fabric, is heat-sensitive. High temperatures can cause it to melt or distort. When steaming, use a low to medium heat setting and avoid placing the steamer too close to the fabric. It’s advisable to test on a small, inconspicuous area first. Steaming is a preferable method for removing wrinkles from polyester compared to ironing, as it’s less likely to damage the fabric if done correctly. Ensure the garment is hung properly and gently tug the fabric to assist in wrinkle removal.

Q polyester density

Polyester fibers are synthetic fibers derived from petrochemical products, through a process called polymerization. The basic structure of polyester fiber is made of long-chain polymers which are composed of ester functional groups within their main chain. This structure provides polyester with several characteristics such as high strength, resilience, and resistance to wrinkles and shrinking. Moreover, polyester fibers can vary in shape and size, from ultra-fine microfibers to larger fibers used in making textiles. The versatility of polyester fibers allows for their use in a wide range of applications, from clothing and home furnishings to industrial materials. Their hydrophobic nature makes them quick drying but also less absorbent than natural fibers, which is a consideration in their use in textiles.
