  • After the application of the formulation to the textile, the method further comprises drying or curing the textile at an elevated temperature, preferably a temperature of 10° C. to 200° C., to finish the treatment process.
  • After treatment with the formulation of the invention, wicking, softening and antistatic properties are essentially locked into the textile to provide such effect to the textile material for an extended number of launderings. For example, the textile exhibits durable wicking, softening and antistatic properties from 1 and 200 home launderings (HLs), preferably after at least 10 HL.
  • FIG. 1 is a diagram illustrating a mechanism for forming a durable wicking softening and antistatic coating on a textile using a formulation in accordance with an embodiment of the present invention.
  • As shown in FIG. 1, an amphoteric surfactant having the formula of:
  • Figure US20200347544A1-20201105-C00001
  • wherein
  • R1=alkyl group
  • G=SO3 or COO (G carries a sulfonate group or a carboxylate group that carries a negative charge)
  • is added to water and stirred to mix.
  • An alkoxysilane having the chemical structure of:
  • Figure US20200347544A1-20201105-C00002
  • wherein
      • R2, R3, R4 and R5=alkyl, alkoxy, aminoalkyl, quaternary ammonium alkyl, or other functional alkyl groups
  • is added to the mixture. The pH is adjusted to a point in the range of 2 and 13 by acetic acid or citric acid solution or NaOH or ammonia solution. It is then stirred for at least 30 minutes if the silane is not already hydrolyzed to form the formulation of the present invention.
  • Applying the formulation to a textile fabric comprised of fibers is believed to form a thin layer of silanol based coating on the fiber surface. After the textile fabric is dried and cured at a high temperature from 10° C. to 200° C., it is theorized that the silanols condense and polymerize to embed the amphoteric surfactant forming a solid film on the fiber, resulting in highly durable amphoteric surfactant coating formulation on the textile fabric.
  • In an embodiment of the invention, the add on level for each of alkoxysilane and of amphoteric or betaine surfactant to the textile is at or above 0.01% by weight based on the weight of dry textile. Preferably, the add on level of alkoxysilane is at or above 0.2% by weight based on the weight of dry textile. Preferably, the add on level for amphoteric or betaine surfactant is at or above 0.5% by weight based on the weight of dry textile.
  • The formulation and method of the present invention are advantageous for a multitude of reasons such as reduction of cost of chemicals and waste treatment.
  • EXAMPLES
  • Testing showed that the formulation of the invention provided durable antistatic, wicking and softening properties after 10 HL.
  • Wicking and antistatic tests were conducted on women's HEATTECH fabric from Nagase before and after 10 HL using the AATCC Monograph 6 method. Room temperature and relative humidity were recorded.
  • Absorbency Testing Method AATCC 79-2014 was used to determine the wicking property of textile materials treated with the formulation of the present invention using the time to absorb a water droplet. Sample pieces were cut into a size of 5×5 in2. A drop of de-ionized water was released onto the fabric center when the time started. When the water droplet disappeared, the time was stopped and recorded. The test was repeated 4 times on four corners. The wicking time was the average of all 5 tests.
  • The antistatic testing method used was adapted from AATCC 76-2011. Sample pieces were cut into a size of 5×5 in2 and laid flat on an insulative bench surface. Surface Resistance Meter Victor 385 was pressed firmly on the fabric center and a “Test” button was pressed until LED light stabilized. The resistance value was recorded. The test was repeated 4 times on four corners. The resistance value was the average of all 5 tests.
  • The percentages of the formulation components shown in Table 1 were based on the weight of the formulation (which was in liquid form) for each of the formulations tested.

  • Treatment
  • A Mathis lab padder model HF-350 was used to treat a textile fabric with each formulation. The textile fabric was Nagase Women's HEATTECH fabric. The nip speed was 3.6 m/min. The pickup rate for each fabric was almost 100% so that the concentration in solution equaled to that on weight of fabric (owf). Immediately following the padding, the fabric was dried and cured in a Mathis lab LTE infrared drier. The cure temp was 150° C.; air temp was 153° C.; fan speed was 1500 rpm and dwell time was 45 s. The treated fabrics along with untreated control fabrics were laundered using an Electrolux front loader washing machine and Tide detergent.
  • Results of the testing are shown in Table 2.
  • TABLE 2
    Wicking, softness and antistatic results
    Wicking (s) Resistance (Ω/cm2) Hand Feel
    Formulation 0 HL 10 HL 0 HL 10 HL 0 HL
    Formula 1 <1 <1 11.6 Insulative Soft as untreated
    Formula 2 <1 <1 11.7 Insulative Soft as untreated
    Formula 3 <1 <1 10.7 Insulative Soft as untreated
    Formula 4 78 2 10.4 Insulative Soft as untreated
    Formula 5 155 >300 11.4 11.0 Soft as untreated
    Formula 6 <1 4 10.0 11.0 Soft as untreated
    Formula 7 <1 <1 9.0 10.0 Soft as untreated
  • Due to the soft hand feel of Nagase Women's HEATTECH fabric, current tested formulations were able to maintain same softness as that of untreated fabric.
  • In Table 2, the wicking time for Formula 7 was less than 1 s before and after 10 HL, compared to 78 s before wash and 2 s after wash of Formula 4. Comparison of Formula 5 and Formula 6, illustrated wicking time decreased from 155 s to less than 1 s before wash, and >300 s to 4 s.
  • Formulations 1, 2, and 3 in Table 2 showed the resistances of fabric treated with only CS-50 at 0.5%, 1% and 3% were 1011.7 Ω/cm2 before washes which meant antistatic. However, after 10 HL their resistance increased and the fabrics turned insulative, suggesting CS-50 only was unable to retain antistatic properties after laundering.
  • Formula 4 without CS-50 showed treated fabric turned insulative after wash, while Formula 7 with CS-50 remained antistatic.
  • As demonstrated by Formula 6 and Formula 7, when hand, wicking and antistatic properties are considered, only the combination of alkoxysilane AEM5700 and amphoteric surfactant CS-50 made durable wicking and antistatic properties to Women's HEATTECH fabric for at least 10 HL.
  • It was noted that an amphoteric surfactant had no durability on fabrics when used alone while the alkoxysilane had no combined wicking, softening and antistatic properties when used alone.
  • It will therefore be readily understood by those persons skilled in the art that the present invention is susceptible of broad utility and application. Many embodiments and adaptations of the present invention other than those herein described, as well as many variations, modifications and equivalent arrangements, will be apparent from or reasonably suggested by the present invention and the foregoing description thereof, without departing from the substance or scope of the present invention. Accordingly, while the present invention has been described herein in detail in relation to its preferred embodiment, it is to be understood that this disclosure is only illustrative and exemplary of the present invention and is made merely for purposes of providing a full and enabling disclosure of the invention. The foregoing disclosure is not intended or to be construed to limit the present invention or otherwise to exclude any such other embodiments, adaptations, variations, modifications and equivalent arrangements.
