Example Embodiment

[0015] Example 1:

[0016] The nano-grade jade powder masterbatch and nylon 6 bright chips are added to the screw synchronously through a separate metering system for spinning. The feed rate of the nano-grade jade powder masterbatch is 95g / min, and the nylon bright chips feed The speed is 3165g / min: the temperature of each zone of the screw is: 235℃, 247℃, 255℃, 258℃, 260℃; spinning box temperature: 258℃; oil load: 1.2%; side blowing speed: 0.6m / min; drawing temperature: 78℃, drawing speed: 4360m / min; winding speed 4350m / min.

[0017] The specifications of the prepared nylon 6 cool jade fiber yarn are FDY70d / 48f, CV%=0.9, breaking strength=4.2CN / dt, breaking elongation=43%; boiling water shrinkage: 9%; full volume rate 80%; Dyeing degree: 4 levels. The body surface contact temperature drops: 2.0℃.

Example Embodiment

[0018] Example 2:

[0019] A separate metering system is used to simultaneously add nano-grade jade powder masterbatch and nylon 6 bright chips to the screw for spinning. The feed rate of the nano-grade jade powder masterbatch is 200g / min, and the nylon big bright chips feed The speed is 3000g / min: the temperature of each zone of the screw is: 238℃, 249℃, 257℃, 260℃, 262℃; spinning box temperature: 261℃; oiling capacity: 1.2%; side blowing speed: 0.6m / min; drawing temperature: 78°C, drawing speed: 4360m / min; winding speed: 4350m / min.

[0020] The specifications of the prepared nylon 6 cool jade fiber yarn is FDY70d / 48f, CV%=0.95, breaking strength=4.3CN / dt, breaking elongation=41%; boiling water shrinkage: 9%; full roll rate 85%; Dyeing degree: 4 levels. The body surface contact temperature drops: 1.5℃.

Example Embodiment

[0021] Example 3:

[0022] A separate metering system is used to simultaneously add nano-grade jade powder masterbatch and nylon 6 bright chips to the screw for spinning. The feeding speed of the nano-grade jade powder masterbatch is 100g / min, and the nylon big bright chips feed The speed is 3150kg / min: the temperature of each zone of the screw is: 235℃, 249℃, 258℃, 260℃, 263℃; spinning box temperature: 260℃; oil capacity: 1.3%; side blowing speed: 0.6m / min; drawing temperature: 80℃, drawing speed: 4360m / min; winding speed: 4350m / min.

[0023] The specifications of the prepared nylon 6 cool jade fiber yarn are FDY70d / 48f, CV%=0.9, breaking strength=4.3CN / dt, breaking elongation=46%; boiling water shrinkage rate: 9%; full roll rate 90%; Dyeing degree: 4 levels. The body surface contact temperature drops: 1.5℃.

Abstract

The invention discloses a preparation method of a chinlon 6 cool jade fiber. The fiber is prepared by the steps of adopting an extraction technology and a nanotechnology, allowing jade and other beneficial mineral materials such as aluminum, silicon, titanium, zirconium and other elements to reach the sub-nanometer particle size, then fusing into a chinlon 6 melt, and carrying out spinning processing to obtain the fiber. The chinlon 6 cool jade fiber has the strength equivalent to a conventional chinlon 6 fiber, has strong wear resistance, has strong cool feel compared with an ordinary silk woven fabric, and is simple in spinning process and high in practicability.

Description

technical field [0001] The invention relates to a preparation method of nylon 6 cool jade fiber; specifically, it is a method for preparing functional nylon 6 fiber by blending and spinning nanometer jade powder refined by nano-extraction technology and nylon 6 melt through screw rods. Background technique [0002] At present, jade fiber is basically polyester cool jade fiber. Shanghai Defulun Chemical Fiber Co., Ltd. uses inorganic nano super cool polyester masterbatch and polyester chips to mix, and produces super cool cool feeling through polyester fiber production process. Healthy polyester fiber. Compared with ordinary polyester fiber, this fiber can improve the cool feeling by more than 20%, and endow the product with excellent UV protection, moisture absorption and perspiration, antibacterial and health care functions. In addition, according to De Fulun, waste plastic bottle flakes and other raw materials are used to process cooling fibers. The products are both cool...
