What is Low melting fiber?
In the ever-evolving field of textile technology, innovation is driving the future of fabric development. One standout advancement is low-melt polyester fiber, a groundbreaking material with unique properties and a wide range of applications that are reshaping industries and pushing the boundaries of fabric engineering.
Low melting point polyester fiber is a type of adhesive fiber used in thermal bonding processes. It is a new technology that is conjugately spun from ordinary polyester and modified low melting point polyester, allowing for environmentally friendly bonding at low temperatures. This material offers excellent shape retention and bonding capabilities when combined with other materials.
The versatility and performance of low-melt polyester fibers are impressive. They have a soft feel, strong bonding effect, and stable heat shrinkage performance. In addition, they possess properties such as anti-pilling, abrasion resistance, flame retardancy, anti-deformation, anti-static, and heat resistance.
Low melting point polyester fibers are utilized across various industries, including clothing, industrial textiles, non-woven fabrics, and environmentally friendly alternatives. In the clothing industry, these fibers improve garment construction, enhancing comfort and longevity. In industrial applications, they strengthen composite materials in automotive and construction sectors. Additionally, they contribute to the production of nonwovens with tailored properties for hygiene, filtration, and industrial uses.
Low Melt Co-PET/PET Fiber
Low Melt Co-PET/PET Short Cut Fiber is a bicomponent fiber featuring a sheath/core concentric structure. It utilizes a low melting point sheath made of Polyethylene and a core material of Polypropylene, complemented by a standard hydrophilic spin finish. This fiber is available in super short lengths of 4, 5, 6, and 12 mm, making it suitable for airlaid applications.
This product is supplied by VNPOLYFIBER and is ideal for airlaid products commonly used in absorbent and insulation applications, including food pads and insulation boards.
