Embodiment 1

[0027] A technical method for eliminating the negative and negative surfaces of carpets, comprising the following steps:

[0028] S1. Select 50% of the matting masterbatch, measure the actual concentration of each batch of matting masterbatch, and guide the dilution of the matting masterbatch with the measured concentration data, and dilute the matting masterbatch to a concentration of 5%;

[0029] S2. Measure the actual concentration of matt masterbatch again. Through the metering and mixing system, accurately measure and mix the matt masterbatch diluted to 5% at a ratio of 1.5% and the ratio of 98.5% of the main raw material nylon 6 slices, and feed it to the screw extrusion The extruder is heated and melted, and the heating temperature in the screw extruder is 255°C, 260°C, 265°C, 268°C, 268°C and 268°C in sequence;

[0030] S3. After the melt passes through the screw extruder, it enters the spinning box for heat preservation. The temperature of the spinning box is 258°C. I...

Embodiment 2

[0035] A technical method for eliminating the negative and negative surfaces of carpets, comprising the following steps:

[0036] S1. Select the matting masterbatch, measure the actual concentration of each batch of matting masterbatch, and use the measured concentration data to guide the dilution of the matting masterbatch, and dilute the matting masterbatch to a concentration of 7%;

[0037] S2. Measure the actual concentration of the matt masterbatch again. Through the metering and mixing system, accurately measure and mix the matting masterbatch diluted to 7% at a ratio of 2% and the ratio of 98% of the main raw material nylon 6 chips, and feed it to the screw extrusion The extruder is heated and melted, and the heating temperature in the screw extruder is 255°C, 260°C, 265°C, 268°C, 268°C and 268°C in sequence;

[0038] S3. After the melt passes through the screw extruder, it enters the spinning box for heat preservation. The temperature of the spinning box is 262°C. It e...

Embodiment 3

[0043] A technical method for eliminating the negative and negative surfaces of carpets, comprising the following steps:

[0044] S1. Select the matting masterbatch whose color number is white 014PA50%, measure the actual concentration of each batch of matting masterbatch, and use the measured concentration data to guide the dilution of the matting masterbatch, and dilute the matting masterbatch to a concentration of 8%;

[0045] S2. Measure the actual concentration of the matt masterbatch again. Through the metering and mixing system, accurately measure and mix the matting masterbatch diluted to 8% at a ratio of 3% and the ratio of 97% of the main raw material nylon 6 chips, and feed it to the screw extrusion The extruder is heated and melted, and the heating temperature in the screw extruder is 255°C, 260°C, 265°C, 268°C, 268°C and 268°C in sequence;

[0046] S3. After the melt passes through the screw extruder, it enters the spinning box for heat preservation. The temperatu...

Abstract

The invention mainly discloses a process method for eliminating the yin and yang surfaces of carpets, and its technical scheme: select the matting masterbatch to be diluted to a concentration of 5% to 8%, and use a metering and mixing system to dilute the matting masterbatch to 5% to 8%. It is mixed with the main raw material nylon 6 slices, fed to the screw extruder for heating, melting and extrusion; after the melt passes through the screw extruder, it enters the spinning box for heat preservation, and enters the melt metering pump to accurately measure and enter the spinning assembly. The filaments are formed through the spinneret; air-conditioned blowing is used to cool and form, and then thermally stretched. The temperature of the drafting roller for thermal stretching is 185-200°C, and the speed of the drafting roller is 3000-3200m / min. Roll, after winding, twist 155-165 twists / m, and finally steam setting. With plump and stiff yarns, it completely eliminates the problems of "yin and yang" and "backward wool" of nylon 6 printed carpets.

Description

technical field [0001] The invention relates to the technical field of carpets, in particular to a process method for eliminating the negative and negative surfaces of carpets. Background technique [0002] Nylon carpet is a new type of carpet made of nylon as raw material and processed by mechanism. Nylon carpet has good dust resistance, and at the same time gives the carpet surface a plump and attractive appearance, so that the vision can always look like new. The application of chemical anti-dust coating technology makes the carpet have a high anti-fouling ability, which can make the surface of the carpet brighter and easier to clean; [0003] At present, carpets will have a "yin and yang side" problem. The so-called "yin and yang side" of nylon printed carpet refers to the traces left by pedestrians or luggage wheels during the use of the carpet, including the inspection process of the carpet. , Wipe it in opposite directions with your hands, and the traces left on the...
