What are the methods for using the non-woven masterbatch to reduce the finished color difference?

1. The amount of non-woven masterbatch added: The amount of masterbatch added directly affects the spinning process and the dyeing effect of the product. The amount of addition is small, the dyeing depth is insufficient or the dyeing is uneven, and if the amount is too much, artificial impurities are formed, which increases the difficulty of spinning. At the same time, since the melting point of the masterbatch is lower than that of the conventional slice, the gray scale is high, so that the melt viscosity changes, the spinnability deteriorates, and the tensile property of the yarn decreases. Practice has shown that when the amount is 1.2% to 3.6%, the finished product is dyed well and the spinning property is good.

2, the mixed position of the non-woven masterbatch: after the masterbatch is different from the quality index of the conventional slice, in order to reduce the thermal decomposition of the masterbatch, the qualified manufacturer, the heating and melting of the masterbatch should be used alone 1 A special small screw is inserted into the melt filter by direct mixing with the melt in the large screw by the metering device.

3, other aspects: In order to reduce the color difference of the finished product, we must pay attention to the following links in production. (1) Establish a standard sample of each masterbatch in a certain ratio, and perform proofing test on the masterbatch after mixing in the factory according to the ratio of the standard sample, and compare it with the standard sample; (2) Entering the factory The masterbatch of the same variety and the same batch is mixed, and the masterbatch of the same variety and different batches is also mixed; (3) Before the masterbatch enters the screw, the masterbatch of excessively large and too small particles should be removed as much as possible. Granules to ensure that they melt evenly and completely in the screw; (4) Try not to change the masterbatch batch number in the middle of producing a color number.

Lu'an Qingsong Masterbatch Co., Ltd. was founded in 2008. After several years of development, it has many advanced production lines, various testing equipments, and employs many senior technicians.
