Abstract
Abstract ABSTRACT OF THE DISCLOSURE Fabric conditioning articles comprising a receptacle releasably containing a pH control agent or electrolyte, and fabric softener/antistat particles which have a coating of an agent which is insolubilized/made indispersible by the pH control agent or electrolyte. The pH control agent or electro-lyte in such articles is separated from the fabric conditioning particles. Additionally, the articles contain uncoated fabric antistat particles. Methods of using the articles are also provided.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
178 words
A fabric conditioning article especially designed for con-ditioning fabrics in a clothes washer and dryer comprising: (A) a water-insoluble closed receptacle having at least a part of one wall comprising a porous material; (B) an effective amount of a fabric softener/antistat composition in the form of individual or agglomerated particles, said particles being coated with a water-soluble/dispersible material and enclosed within the receptacle of (A); (C) an amount of a solid, particulate agent selected from the group consisting of electrolytes, pH control agents and mixtures thereof sufficient to make the coatings of (B) water-insoluble/ indispersible in the volume of wash water in which they are used, said agent enclosed within the receptacle of (A); and (D) an effective amount of fabric antistat particles comprising a mixture of a dispersion inhibiting agent and an antistat agent, said particles enclosed within the receptacle of (A); wherein the agent of (C) is physically separated from the particles of (B) within the receptacle of (A), and the weight ratio of component (D) to component (B) is from about 1:120 to about 5:1.
Claim 2
Dependent Claim

Claim 9
Dependent Claim
57 words
An article according to Claim 7 wherein the physical separation is accomplished by splitting the pouch of (A) into two parts through the use of a sealing agent and placing the particles of (B) into one part, the agent of (C) into the other and splitting equally the fabric antistat particles of (D) between the two parts.
