Description

Fiber processing agent for composite fiber knitted fabric and composite fiber knitted fabric treated with this processing agent {Treatment agent for complex knitting textile and the knitting textile treated therewith}

The present invention relates to a fiber processing agent for a composite fiber knitted fabric and a composite fiber knitted fabric treated with the processing agent.

In order to increase the elasticity of the composite fiber knitted fabric, an elastic silicone oil emulsified product and a water-soluble urethane product are used. However, the elastic silicone oil emulsified product has a soft touch, but has a disadvantage of insufficient elasticity and antifouling property. The water-soluble urethane product has the characteristics of elasticity, sweat absorption and quick-drying, but has a disadvantage in that soft touch is insufficient.

In order to supplement the shortcomings of the elastic silicone oil emulsified product and the water-soluble urethane product, there are products processed to include the water-soluble urethane in the elastic silicone oil emulsified product, or processed to include the elastic silicone oil emulsified product in the water-soluble urethane synthetic product. However, these products also lack storage stability and most of them have a soft touch.

In addition, the processed products have a weak alkali stability of the pH alkali 9 in the processing process, the cracking phenomenon and sticking (gumming) of the silicone oil is a lot of defects appear in the processing process more than 10%.

Wherein n is an integer of 1 or more.

Referring to one embodiment of a method for producing a fiber processing agent for the composite fiber knitted material by synthesizing the two water-soluble urethane and OH group silicone oil as follows.

In a synthesis apparatus including a condenser, a stirrer, a nitrogen injector, and a thermometer, 6.72% by weight of polyol, 10% by weight of isocyanate, 0.96% by weight of -OH-based Hydroxysilicone oil, and 0.5% by weight of a catalyst are added to the synthesis device. It puts into a container and makes it react for 3 hours at the temperature of 80 degreeC-85 degreeC. The catalyst may be sulfuric acid, phosphoric acid, methyl sulfuric acid, paratoluene sulfuric acid or tin compound. The present invention is not limited to the above catalyst, and can be used to react polyols, isocyanates and OH-based Hydroxy silicone oils.

After the reaction for 3 hours, Isocyanate Terminated Polyurehtae Propolymer was prepared, and then reacted until the isocyanate peak was reduced to 25% by checking the degree of reaction of the isocyanate using infrared spectroscopy (FTIR).

When the isocyanate peak is reduced to 25%, 1% by weight of trimethylolpropane (TMP) and 0.25% by weight of polymethacrylic acid (PMA) are added and reacted at a temperature of 80 ° C to 85 ° C for 1 hour 30 minutes. .

The trimethylolpropane (TMP) and polymethacrylic acid (PMA) were added and reacted until the isocyanate peak was reduced to 15%. When the isocyanate peak is reduced to 15%, the internal temperature of the reactor is cooled to 50 ° C, and 0.5% by weight of a blocking agent is added to react for 1 hour. At this time, it is reacted until the isocyanate peak becomes 0%.

While maintaining the temperature inside the reactor to 50 ℃ or less while stirring a small amount of water while stirring at a maximum speed of 200rpm.

Preferably, the present invention is characterized in that the particle size is 100nm to provide a fiber processing agent having stability. Generally, the fiber processing agent has a size of 500 nm or more. If the particle size of the fiber processing agent is 500 nm or more, there is a problem in that the lack of stability, gumming occurs.

(◎: Very good, ○: Good, ×: Bad)

In Table 1, the fiber processing agent of Comparative Example 1 was emulsified by adding the same amount of modified amino silicone oil to the yeast mixer in the fiber processing agent of Example 1 in the OH group silion oil. Comparative Example 1 was processed with the same amount of solids as in Example 1, but it can be seen that antifouling properties, resilience and touch were less than those in the Examples.

In addition, Comparative Example 2 was not fiber-treated, compared with the processed Example 1 and Comparative Example 1 was confirmed that all of the antifouling properties, resilience and touch are bad.

For the antifouling test, Example 1 includes two drops of light oil and bunker C oil on the fabric of the composite fiber knitted fabric treated with the fiber processing agent for the composite fiber knitted fabric in which the water-soluble urethane and OH-based silicone oil were synthesized in a 9: 1 ratio. After dropping the contaminated fabric in water and then check the antifouling properties. In Comparative Example 1, two drops of light oil and bunker C oil were dropped on a fabric processed with a fiber processing agent emulsified by adding modified amino silicone oil, and then stained with contaminated fabric, and then stain resistance was confirmed. In Comparative Example 2, two drops of diesel oil and bunker C oil were dropped on the unprocessed composite fiber knitted fabric, and the soil was immersed in the contaminated fabric.

Referring to Figure 1, the antifouling test results showed that the antifouling property of the composite fiber knitted fabric (Example 1) treated with a fiber processing agent for a composite fiber knitted fabric of a water-soluble urethane and OH-based silicone oil in a 9: 1 ratio.

Repulsive elasticity test is measured according to ASTM D 2594. The repulsive elastic test method is to place the test specimen on a flat surface and measure the height of the spring bouncing ball free fall at the same height. Example 1 confirmed that the resilience was increased by 30% and the elastic force was increased by 20% compared to Comparative Example 1.

In addition, the first embodiment is treated with a fiber processing agent for a composite fiber knitted composite of a water-soluble urethane and OH-based silicone oil in a 9: 1 ratio in the composite fiber knitted fabric, both the resilient elasticity and the touch feeling with a soft touch Excellent results were obtained.

In Comparative Example 1, the resilience was 10%, and it was confirmed that both the elastic force and the touch feeling were less than those of the examples due to the somewhat stiff hand.

Stability test at pH 10 was carried out using 30 g / l of a fiber processing agent for a composite fiber composite in which a water-soluble urethane and an OH-based silicone oil were synthesized in a 9: 1 ratio, and then using 9OH, 10 pH, and 11 pH using NaOH (5% by weight). And stability at 45 ° C. after soaking in a solution adjusted to 12 pH respectively.

Referring to FIG. 2, Examples 2 and 3 have alkali stability without a gum up phenomenon. However, in Comparative Examples 3 and 4, suspended matter is formed and a gum up phenomenon occurs and the phenomenon of sticking to the inner wall of the container appears.

That is, the fiber processing agent for the composite fiber knitted fabric of the water-soluble urethane and the OH-based silicone oil of the present invention synthesized in a 9: 1 ratio has a stability at pH 9 to 10, thereby removing the cracking phenomenon and the gumming of the silicone oil. In the process of processing the composite fiber knitted fabric, there is an effect that the failure rate is reduced.
