Deodorizing nylon 6 fiber and preparation method thereof

A preparation method of a deodorizing nylon 6 fiber, comprising:

• providing a fabricating step of deodorizing nylon 6 chips, comprising:
• performing a mixing step, wherein a porous powder of citrate is mixed with a caprolactam powder so as to obtain a raw material of a deodorizing chip, a weight ratio of the porous powder of citrate ranges from 2% to 6% based on a weight ratio of the raw material of the deodorizing chip as 100%, and a weight ratio of the caprolactam powder ranges from 94% to 98% based on the weight ratio of the raw material of the deodorizing chip as 100%;
• performing a nano-grinding step, wherein the raw material of the deodorizing chip is ground so as to obtain a size mixture of a deodorizing nylon 6, and an average diameter of the size mixture of the deodorizing nylon 6 ranges from 100 nm to 200 nm;
• performing a granulated polymerizing step, wherein the size mixture of the deodorizing nylon 6 is polymerized so as to obtain the deodorizing nylon 6 chips;
• performing a viscosity adjusting step, wherein a relative viscosity of the deodorizing nylon 6 chips is adjusted to a range from 2.20 mPa·s to 2.30 mPa·s;
• and
• performing a water content adjusting step, wherein a water content ratio of the deodorizing nylon 6 chips is adjusted to a range from 350 ppm to 550 ppm;
• and
• performing a spinning step, comprising:
• providing a spinning material, wherein the spinning material comprises the deodorizing nylon 6 chips performed the viscosity adjusting step and the water content adjusting step;
• and
• performing a melt fluxing step, wherein the spinning material is spun under a temperature ranging from 255° C. to 265° C. so as to obtain a deodorizing nylon 6 fiber.
