Low melting fiber can be melted at temperatures such as ~100~200°C that bond with other fibers deprived of any injurious adhesives compared to normal polyester fiber, which can be melted at higher temperatures above 280°C. This property subsidizes environmental preservation by producing low heat and carbon dioxide. It finds application in several areas such as door trims, automotive car interiors, ceiling materials, headliners, construction, furniture, and the industrial sector.
Low-melting fiber is referred to as a “bi-component fiber,” which has strong bonding properties. The low-melting fiber is used in the spinning of durable yarns. Moreover, this fiber is used as excellent insulating material in the automotive and construction industries due to its complex structure. Furthermore, this fiber is blended with solid recycled material or solid polyester fibers, which are then used for car molding. The low-melting fiber provides effortless bonding and high elasticity and thus is used for the production of interior parts of cars, mattresses, and medical goods, among others.
“Low melting fiber” refers to a bi-component fiber used as a thermal bonding fiber, and its structure is typically a sheath/core type. It is composed of a sheath polymer and a core polymer. The melting point of the sheath polymer is lower than that of the core polymer.
The low-melting fiber offers various benefits, such as low melting points, durability, and high bonding strength. Moreover, it is blended with other types of fibers and is used to manufacture padding, interlining, and high-quality mattresses. Furthermore, it is used to manufacture sanitary and medical products. The various advantages of low-melting fiber will therefore probably increase demand for the product worldwide.
Low-melt fibers utilize sheath-core fibers that melt at high temperatures and bond with other fibers to provide excellent matrix stability and handling characteristics. Low-melt fibers also enhance cushioning product quality and are more compatible with the environment.
Low-melting fiber can be melted at a lower temperature (~100~200°C), making it possible to be bonded with other fibers without any harmful adhesives, compared with normal polyester fiber, which is melted at a higher temperature of more than 280°C. This property contributes to environmental conservation by generating less carbon dioxide and heat. Its applications vary from automotive car interiors (door trims, ceiling materials, headliners, etc.) to furniture, construction, and industrial use.
Non-woven fibers are run through either a hot-air oven, a calendar or an infrared heater. This leads to soldering the fibers together when the low-melt fibers melt and flow around the standard polyester fibers. For high-loft nonwovens, this process is the primary bonding method and a secondary one when needled nonwoven fibers are to be heated to give more strength.
What is a bicomponent fiber?
By blending two kinds of polymers, new fibers are made that own every characteristic of each polymer.
Bi-component binder fibers with high-performance ability.
Bicomponent fibers have various types that are suitable for heat-bonded nonwoven fabrics, depending on their purpose and application (carding, wet-laid, and air-laid).
Bicomponent fibers offer several advantages, including a soft touch, durable performance, process stability, and high speed, and they have different melting points based on the raw materials used, which allows for significantly higher material strength.
The first specific characteristic of bi-component fibers is the difference in melting points between the two polymers, which causes one polymer to act as glue for bonding the two fibers together.
What is biodegradable fiber?
“Biodegradable” means that it can be biodegraded using microorganisms. It is often connected with biodegradable materials.
“Biodegradable materials” refer to materials that can be completely decomposed into low-molecular compounds by microorganisms (such as bacteria, fungi, algae, etc.) under appropriate and definite natural environmental conditions.
Fully biodegradable materials can be completely decomposed by microorganisms and have a positive effect on the environment.
While human beings create modern civilization, it also brings negative impacts—light pollution. Disposable tableware, disposable plastic products, and agricultural mulch are difficult to recycle, and their treatment methods are mainly incineration and landfill. Incineration will produce a large amount of harmful gases that pollute the environment; if buried, the polymers in it cannot be decomposed by microorganisms in a short time and also pollute the environment. Residual plastic films exist in the soil, hindering the development of crop root systems and the absorption of water and nutrients, making the soil The air permeability is reduced, resulting in crop yield reduction; after eating the discarded plastic film, it will cause intestinal obstruction and death; synthetic fiber fishing nets and fishing lines lost in the ocean or discarded in the ocean have caused considerable damage to marine life.
Therefore, it is imperative to promote green consumption and strengthen environmental protection.
