Abstract
Abstract An article for conditioning fibrous materials by contact includes a form-retaining base and, held to an outside surface of the base in form-retaining relationship with it, a flexible material which has an outer surface thereof containing a fiber conditioning agent. Conditioning effected is preferably fabric softening and may take place in an automatic laundry dryer wherein damp laundry is brought into tumbling contact with the conditioning article while being dried. Such contact causes the transfer to the laundry of softening agent and the dried laundry is satisfactorily soft, non-static and unwrinkled, upon removal from the dryer. Also disclosed are packages for the articles wherein the formretaining base is a paperboard cylinder and is employed as a container for the flexible material coated with softening agent.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
46 words
An article according to claim 1 wherein the fabric softener is a waxy composition which extends beyond the surface of the flexible paper and which comprises, as an active fabric softening constituent, an organic nonionic, anionic, cationic or mixed anionic-nonionic or cationic-nonionic surface active softening agent.
Claim 2
Dependent Claim
49 words
An article according to claim 2 wherein the form-retaining base is tubular and the flexible material is fastened to the exterior of the tube by fastening means and is removable from the tube after use and consumption of substantially all the fabric softening agent at the outer surface thereof.
Claim 3
Dependent Claim
31 words
An article according to claim 5 wherein the form-retaining tubular base is of paperboard, cardboard or corrugated board construction and the thin sheet or strip of flexible material is of paper.
Claim 4
Dependent Claim
35 words
An article according to claim 4 wherein the paper is coated on both sides with fabric softener so as to be reversible on the tubular base after consumption of the softener from one side thereof.
Claim 5
Dependent Claim
66 words
An article according to claim 4 wherein the means for holding the flexible material to the form-retaining base comprises end sections of the paper which extend beyond the length of the tubular base and are capable of being folded into the ends of the tubular portion thereof, to hold the rest of the sheet or strip in form-retaining relationship with the outer surface of the tube.
Claim 6
Dependent Claim
28 words
An article according to claim 6 wherein the end sections of the paper are uncoated in the portions thereof which extend beyond the length of the tubular base.
Claim 7
Dependent Claim
25 words
An article according to claim 3 wherein the tubular base is a cylinder which is telescopic with a roll of paper containing the conditioning agent.
Claim 8
Dependent Claim
87 words
A package of materials of a fiber conditioning article which comprises a form-retaining tubular base and a quantity of flexible material having an outer surface containing thereon a fiber conditioning agent for the treatment of fibrous materials by contact therewith, which quantity is sufficient for making a pluRality of covers for the base, with the quantity of flexible material being packed in telescopic relationship with the base, whereby the base performs the function of a packaging element for the quantity of flexible material containing fiber conditioning agent.
Claim 9
Dependent Claim
40 words
A package according to claim 9, wherein the form-retaining tubular base is an outer cylinder and the quantity of flexible material having an outer surface thereof containing a fiber conditioning agent is in roll form, packed in the base cylinder.
Claim 10
Dependent Claim
68 words
An article for conditioning fibrous materials making contact with it which comprises a form-retaining base and, held to an outside surface of such base, in form-retaining relationship with it, a flexible material having an outer surface containing thereon a fiber conditioning agent which, during a tumbling operation, is transferable to the fibrous materials contacted, to condition them, said fiber conditioning agent being a fabric softener or antistatic agent.
Claim 11
Independent Claim
119 words
A method for conditioning fibrous materials which comprises contacting such materials with a fiber conditioning article comprising a form-retaining base, and held to an outer surface of such base in form-retaining relationship with it, a flexible material having an outer surface containing thereon a fiber conditioning agent, and tumbling fibrous materials to be conditioned in contact with the article until a sufficient quantity of fiber conditioning agent is transferred to the fibrous materials to condition them, the fibrous materials being conditioned being items of laundry in a damp state, the fiber conditioning agent being a fabric softener and the contacting occurring in an automatic laundry dryer during tumbling contact of the damp laundry being dried with the conditioning article.
