Embodiment 1

[0019] Example 1: In this example, a method for producing colored nylon DTY gloves special yarn, the steps are:

[0020] a. Dry the black masterbatch. The drying temperature of the masterbatch is 85°C and the drying time is 4.5 hours. Then add the masterbatch to the masterbatch machine, and then mix the masterbatch and nylon chips into the screw extruder. Extrusion and melting, the viscosity of the nylon chip is 2.45, and the added masterbatch accounts for 3.5% of the total mass after mixing;

[0021] b. Put the melted mixture into the spinning box for spinning. The temperature in the spinning box is 262°C and the spinning speed is 4250m / min. The thread is metered by a spinning metering pump, and then passed into the jet The silk components are spun, then cooled, oiled, and wound into POY;

[0022] c. Pass the POY into the texturing machine for texturing to form the original yarn, and then pass the original yarn through the roller for under-stretching, the stretching ratio is 1.26, ...

Embodiment 2

[0025] Example 2: The production method of a colored nylon DTY glove special yarn of this example, the steps are:

[0026] a. Dry the gray masterbatch. The drying temperature of the masterbatch is 90℃ and the drying time is 5 hours. Then it is added to the masterbatch machine, and then the masterbatch and nylon chips are mixed and put into the screw extruder. Extrusion and melting, the viscosity of the nylon chip is 2.45, and the added masterbatch accounts for 4% of the total mass after mixing;

[0027] b. Put the melted mixture into the spinning box for spinning. The temperature in the spinning box is 258°C and the spinning speed is 4300m / min. The thread is measured by a spinning metering pump, and then it is fed into the jet The silk components are spun, then cooled, oiled, and wound into POY;

[0028] c. Pass the POY into the texturing machine for texturing to form the original yarn, and then pass the original yarn through the roller for under-stretching, the stretching ratio is ...

Embodiment 3

[0032] Example 3: The production method of a colored nylon DTY glove special yarn of this example, the steps are:

[0033] a. Dry the bleached masterbatch. The drying temperature of the masterbatch is 90℃ and the drying time is 7 hours. Then it is added to the masterbatch machine, and then the masterbatch and nylon chips are mixed and put into the screw extruder. Extrusion and melting are carried out inside, the viscosity of the nylon chip is 2.42, and the added masterbatch accounts for 2.5% of the total mass after mixing;

[0034] b. Put the melted mixture into the spinning box for spinning. The temperature in the spinning box is 257°C, and the spinning speed is 4300m / min. The thread is measured by a spinning metering pump, and then it is fed into the jet The silk components are spun, then cooled, oiled, and wound into POY;

[0035] c. Pass the POY into the texturing machine for texturing to form the original yarn, and then pass the original yarn through the roller for under-stretc...

Abstract

The invention relates to a production method for nylon-6 fiber, in particular to a production method for colored nylon DTY glove special-used silk, which mainly solves technical problems that the existing technology can not be used for producing colored nylon, the existing other methods for manufacturing colored nylon has higher cost during dying, and causes environmental pollution, and the manufactured colored nylon has worse elasticity and shrink ability, is not suitable for manufacturing gloves and the like. The production method comprises the following steps: drying color master batches and then adding the color master batches into a color master batch machine, mixing, extruding and melting the color master batches and the nylon slices which are spun, injected, cooled, oiled and woundto form POY, adding the POY into an elasticizer for being elasticized to form grey yarn which is stretched and yarned by a roller, and then heated, cooled, false-twisted in sequence, and oiling and winding again after false-twisted strand silk is secondly rolled to obtain finished colored nylon DTY glove special-used silk.

Description

Technical field [0001] The invention relates to a production method of nylon-6 fiber, in particular to a production method of colored nylon DTY gloves special yarn. Background technique [0002] The fabrics processed by traditional ordinary nylon-6 fibers need to be dyed, printed or bleached before they can become reprocessed commodities or semi-finished products. The Chinese patent discloses a production method of nylon 6 micro-denier fully drawn yarn (authorized announcement number: CN1262694C), which in turn includes the following steps: ① melting: introduce nylon 6 raw material slices into a screw extruder to melt, so that the raw material is Melt; ②Forming: transport the above-mentioned molten material to the spinning box, press into the high-pressure components to form thick filaments; the temperature in the spinning box is 262~268℃; ③Cooling: the above thick filaments enter the slow The cold zone is subjected to slow cooling treatment and side air blowing treatment, and t...
