The high-temperature shaping in the step (2) adopts a reverse-side gum process, the brushing speed is 3.8m/min, and the gauge is 0.25 mm; the lustre finishing speed is 14m/min, and the temperature is 210 ℃; heating dyeing process bath ratio: 1: temperature 150 ℃, ramp rate: 1.2 ℃/min, and the heat preservation time is 40 min; the temperature of the cooling dyeing process is 100 ℃, and the cooling dyeing time is 25 min; the temperature of the deep color reduction cleaning process is 100 ℃, the time is 30min, and 5g/L of caustic soda flakes and 5g/L of sodium hydrosulfite are added in the cleaning process.
The formula of the softening agent in the step (4) is as follows: 10g/L of softening agent WS-3, 1g/L of antistatic agent and 10kg of stock solution; the bath ratio is 1: 9, the temperature is 55 ℃, and the time is 20 min; the temperature of the reduction cleaning was 85 ℃ and the speed was 18 m/min.
Comparative example 1:
comparative example 1 differs from example 1 in that the yarns were not loaded with fumed silica additive and the remaining process and raw materials were the same as in example 1.
Comparative example 2:
comparative example 2 differs from example 2 in that the fumed silica additive added to the yarn did not adsorb CO2The rest of the process and the raw materials were the same as in example 2.
Comparative example 3:
the difference between the comparative example 3 and the example 3 is that the yarn is solid core polyester fiber, and the rest of the process and the raw materials are the same as those of the example 3.
The color fixing rate and the heat retention property of the carpets in the above examples and comparative examples were respectively tested, and the softness and the gloss of the carpets were evaluated by sense, and the results were as follows:
in the invention, the blanket heat retention is measured by adopting a JIS (JIS) heat retention rate evaluation method, five testers are selected to respectively grade the softness and the glossiness of the blanket through sense organ (the full score is 10 points), and the average score is taken.
As can be seen from the table, the carpet with the fumed silica additive saturated with adsorbed CO2 exhibited the best fixation, warmth, softness, and gloss. Specifically, comparative example 1 shows the lowest fixation rate, while comparative example 1 and comparative example 2 have small difference in fixation rate and are respectively different from the examples, which shows that the addition of fumed silica plays an important role in improving the fixation rate, and the fumed silica adsorbs CO in a saturated manner2Plays a key role because of adding saturated adsorption CO2The fumed silica can prevent the spinning solution from blocking the pore channels of the fumed silica; the thermal insulation property, the softness and the glossiness are analyzed, the double-hollow polyester fiber is adopted, the effect is obviously improved, the hollow polyester fiber is lighter and warmer, the fiber weight is reduced due to the high-hollow structure, a large amount of static air can be contained, the thermal insulation property of the fabric is greatly improved compared with that of a common homogeneous fabric while the fabric is light, and in addition, the fumed silica is also beneficial to improving the thermal insulation property, the softness and the glossiness.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiment according to the technical spirit of the present invention still belong to the protection scope of the technical solution of the present invention.
