Abstract

Dryer products that impart antistatic properties to textiles and methods for fabricating such dryer products are provided. In one exemplary embodiment, a dryer product comprises a water-insoluble, moisture-permeable, enclosed container and a desiccant within the water-insoluble, moisture-permeable, enclosed container. The desiccant is adapted to impart antistatic properties to the textiles during a drying cycle. In another exemplary embodiment, a method for fabricating a reusable antistatic dryer product comprises the steps of providing a desiccant adapted to absorb moisture and be solubilized in the moisture, depositing the desiccant in a water-insoluble, moisture-permeable container, and enclosing the desiccant within the water-insoluble, moisture-permeable container.

Claims (27)

1. A dryer product that imparts antistatic properties to textiles, the dryer product comprising:

a water-insoluble, moisture-permeable, enclosed container, adapted to be removably placed within the drum of a dryer for contacting with the textiles during a drying cycle; and

a compound within the water-insoluble, moisture-permeable, enclosed container, wherein the compound comprises a material that is:

a) a desiccant adapted to absorb moisture from textiles during the drying cycle;

b) an antistatic agent adapted to impart antistatic properties to the textiles during a drying cycle upon contact with the textiles during the drying cycle; and

c) a material that, after absorbing moisture from the textiles during the drying cycle, solubilizes and evaporates from the water-insoluble, moisture-permeable, enclosed container upon application of heat to the container during the drying cycle,

wherein the water-insoluble, moisture-permeable, enclosed container contains a sufficient amount of the compound such that the dryer product can be used for more than one drying cycle while still imparting antistatic properties to the textiles being dried so that static electricity produced during each of the more than one drying cycle is no more than 10 kilovolts.

2. The dryer product of claim 1 , wherein the compound comprises a material selected from the group consisting of hydrated calcium chloride, potassium chloride, sodium chloride, and combinations thereof.

3. The dryer product of claim 2 , wherein the compound comprises about 70 to about 100 wt. % hydrated calcium chloride.

4. The dryer product of claim 1 , wherein the compound is in the form of granules, beads, flakes, coins, chips, or a combination thereof.

5. The dryer product of claim 1 , wherein the water-insoluble, moisture-permeable, enclosed container is comprised of a material selected from the group consisting of polyethylene, polyester, polypropylene, polyamides, acrylic, nylon, acetate, rayon, paper materials, cellulose materials, non-cellulosic materials, and combinations thereof.

6. The dryer product of claim 1 , wherein the water-insoluble, moisture-permeable, enclosed container comprises acetate taffeta.

7. The dryer product of claim 1 , wherein the water-insoluble, moisture-permeable, enclosed container is treated with an antistatic component, a fabric softening agent, a wrinkle reducer, fragrance, bleaching agents, stain removers, antibacterial materials, antimicrobial materials, antiviral materials, hygienic materials, or a combination thereof.

8. The dryer product of claim 1 , further comprising an additional antistatic component, a fabric softening agent, a wrinkle reducer, fragrance, a bleaching agent, a stain remover, an antimicrobial material, an antibacterial material, an antiviral material, a hygienic material, or a combination thereof within the water-insoluble, moisture-permeable, enclosed container.

9. A method for fabricating a reusable dryer product adapted to impart anti-static properties to textiles during a drying cycle, the method comprising the steps of:

providing a compound that comprises a material that is:

a) a desiccant adapted to absorb moisture from the textiles during the drying cycle;

b) an antistatic agent adapted to impart antistatic properties to the textiles during a drying cycle upon contact with the textiles during the drying cycle; and

c) a material that is adapted to be solubilized after absorbing the moisture from the textiles during the drying cycle and evaporated upon application of heat during the drying cycle;

depositing the compound in a water-insoluble, moisture-permeable container, the water-insoluble, moisture-permeable container being adapted for removable placement within the drum of a dryer for contacting the textiles during a drying cycle; and

enclosing the compound within the water-insoluble, moisture-permeable container, in an amount such that the dryer product can be used for more than one drying cycle while still imparting antistatic properties to the textiles being dried so that static electricity produced during each of the more than one drying cycle is no more than 10 kilovolts.

10. The method of claim 9 , wherein the step of providing a compound comprises providing a compound comprising a material selected from the group consisting of hydrated calcium chloride, potassium chloride, sodium chloride, and combinations thereof.

11. The method of claim 10 , wherein the step of providing a compound comprises providing a compound comprising about 70 to about 100 wt. % hydrated calcium chloride.

12. The method of claim 9 , wherein the step of depositing comprises depositing the compound in a water-insoluble, moisture-permeable container comprising a material selected from the group consisting of polyethylene, polyester, polypropylene, polyamides, acrylic, nylon, acetate, rayon, paper materials, cellulose materials, non-cellulosic materials, and combinations thereof.

13. The method of claim 9 , wherein the step of depositing comprises depositing the compound in a water-insoluble, moisture-permeable container comprising acetate taffeta.

14. The method of claim 9 , further comprising the step of treating the water-insoluble, moisture-permeable container with an antistatic component, a fabric softener, a wrinkle reducer, a fragrance, a bleaching agent, a stain removing agent, an antimicrobial material, an antibacterial material, an antiviral material, a hygienic material, or a combination thereof.

15. The method of claim 9 , further comprising the step of depositing an additional antistatic component, a fabric softening agent, a wrinkle reducer, fragrance, a bleaching agent, a stain remover, an antimicrobial material, an antibacterial material, an antiviral material, a hygienic material or a combination thereof within the water-insoluble, moisture-permeable container.
