Polyamide and polyester sheath-core functional fiber and manufacturing method

Abstract

A polyamide and polyester sheath-core functional fiber and manufacturing method are provided. Section of the polyamide and polyester sheath-core functional fiber is an abnormal sheath-core compound structure. Common PET (terylene) polyester forms abnormal sheath-core of fiber and functional PA (polyamide) with negative oxygen ion and far infrared ray forms abnormal sheath layer of fiber. The manufacturing method is as follows: using a complex fiber-spinning machine, using an abnormal central orifice of same plate bi-component sheath-core distributing plate and corresponding an abnormal spinneret orifice of spinneret plate as complex fiber-spinning assembly; material quality proportion of two components sheath and core is 1.5:8.5 to 5:5. Fiber abnormal sheath layer PA uses melt spinning temperature which is 3 to 10 DEG. C higher than conventional spinning temperature so that melt viscosity is reduced, which leads to high compatibility penetrating each other in larger area edge between the PET melt and the PA. It is hard to peel off two components of polyamide and polyester. The filament has larger specific surface and is easy to release negative oxygen ions constantly and effectively above 5500/cu.cm. Far infrared transmissivity is above 0.86. The invention is iron hand in the velvet glove and wearable. The fiber product is multifunctional, high in quality, which satisfies subsequent manufacturing demand greatly and improves quality of final product and is simple in manufacturing process, low in cost with good effects.

AI Technical Summary

Benefits of technology

This patented technology involves making fibers that release negatively charged particles called nitrogen oxide near infrared rays when exposed to light or heated objects like car windows or walls for longer periods than usual without losing their strength over time. These fibers are durable and resistant to damage from external factors like weather conditions. They have excellent properties suitable for use indoors where they will come into contact frequently while still providing effective protection against harmful ultraviolet radiation.

Problems solved by technology

This patented technical problem addressed in this patents relates to adding negatively charged particles (oxygen) near or inside an object made from synthetic polymers such as plastic foam material without compromising its properties like durability, comfortableness, anti-bodily property, etc., which could help reduce harm caused by excessive exposure to atmospheric gases including nitrogen oxides (NOx).
