Abstract
Abstract A finishing process for textile fabrics is disclosed which imparts to the fabric reduced permeability to down, fiberfill or other insulating materials. A curable finishing formulation containing silicone compounds and filler materials is applied to the fabric, dried and cured and the fabric may thereafter be calendered.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
123 words
A fabric formed of textile yarns and having a finish which significantly reduces the size of the interstices between the yarns so as to prevent the penetration of down, fiberfill or other insulating materials, and which is characterized by enhanced finish retention and reduced dusting, said fabric having a durable coating thereon forming a thin film at the surface of the fabric and bridging between intersecting yarns so as to at least partially fill the interstices between the yarns of the fabric and to durably reduce the permeability of the fabric, said coating comprising a cured reactive silicone polymer, a crosslinked durable-press finishing agent, and a starch filler dispersed in a matrix of said silicone polymer and being bound to the fabric thereby.
Claim 2
Dependent Claim
123 words
A fabric formed of textile yarns and having a finish which significantly reduces the size of the interstices between the yarns so as to prevent the penetration of down, fiberfill or other insulating materials, and which is characterized by enhanced finish retention and reduced dusting, said fabric having a durable coating thereon forming a thin film at the surface of the fabric and bridging between intersecting yarns so as to at least partially fill the interstices between the yarns of the fabric and to durably reduce the permeability of the fabric, said coating comprising a cured reactive silicone polymer, a crosslinked durable-press finishing agent, and a starch filler dispersed in a matrix of said silicone polymer and being bound to the fabric thereby.
Claim 3
Dependent Claim
15 words
A fabric according to claim 1 wherein said durable-press finishing agent comprises an n-methylol resin.
Claim 4
Dependent Claim
13 words
A fabric according to claim 1 wherein said coating additionally includes a catalyst.
Claim 5
Dependent Claim
117 words
A fabric formed of textile yarns and having a finish which significantly reduces the size of the interstices between the yarns so as to prevent the penetration of down, fiberfill or other insulating materials, and which is characterized by enhanced finish retention and reduced dusting, the yarns of said fabric having a calendered, flattened configuration reducing the permeability of the fabric, and said fabric having a coating thereon forming a thin film at least partially filling the interstices between the yarns of the fabric so as to durably reduce the permeability of the fabric, said coating comprising a cured reactive silicone polymer and a starch filler distributed throughout cured silicone polymer and bound to the fabric thereby.
Claim 6
Dependent Claim
117 words
A fabric formed of textile yarns and having a finish which significantly reduces the size of the interstices between the yarns so as to prevent the penetration of down, fiberfill or other insulating materials, and which is characterized by enhanced finish retention and reduced dusting, the yarns of said fabric having a calendered, flattened configuration reducing the permeability of the fabric, and said fabric having a coating thereon forming a thin film at least partially filling the interstices between the yarns of the fabric so as to durably reduce the permeability of the fabric, said coating comprising a cured reactive silicone polymer and a starch filler distributed throughout cured silicone polymer and bound to the fabric thereby.
Claim 7
Dependent Claim
28 words
A fabric according to claim 4 wherein said yarns are formed at least partially of cellulosic fibers and said cured silicone polymer is crosslinked with the cellulosic fibers.
Claim 8
Independent Claim
111 words
A method for finishing a fabric formed of textile yarns to reduce the size of the interstices between the yarns so as to prevent the penetration of down, fiberfill or other insulating materials, and wherein the fabric is also characterized by enhanced finish retention and reduced dusting, said method comprising applying to the fabric a curable finishing composition comprising a mixture of a reactive silicone polymer and a starch filler, heating the fabric to dry and cure the finishing composition and form a thin film of said polymer and starch filler at least partially filling the interstices between the yarns of the fabric and durably reducing the permeability of the fabric.
Claim 9
Independent Claim
111 words
A method for finishing a fabric formed of textile yarns to reduce the size of the interstices between the yarns so as to prevent the penetration of down, fiberfill or other insulating materials, and wherein the fabric is also characterized by enhanced finish retention and reduced dusting, said method comprising applying to the fabric a curable finishing composition comprising a mixture of a reactive silicone polymer and a starch filler, heating the fabric to dry and cure the finishing composition and form a thin film of said polymer and starch filler at least partially filling the interstices between the yarns of the fabric and durably reducing the permeability of the fabric.
Claim 10
Dependent Claim
26 words
A method according to claim 6 including the further step of calendering the fabric following said heating step to further reduce the permeability of the fabric.
Claim 11
Dependent Claim
32 words
A method according to claim 7 wherein said step of calendering the fabric is performed with a heated roll and with sufficient pressure to effect flattening of the yarns forming the fabric.
Claim 12
Dependent Claim
20 words
A method according to claim 8 wherein said heated roll has a surface temperature of from 175° to 450° F.
Claim 13
Dependent Claim
22 words
A method according to claim 6 including the further step of applying to the fabric and curing thereon an additional coating composition.
Claim 14
Dependent Claim
25 words
A method according to claim 6 wherein said step of applying a curable finishing composition comprises padding the finishing composition to thoroughly impregnate the fabric.
Claim 15
Dependent Claim
23 words
A method according to claim 6 wherein said step of applying a curable finishing composition comprises rotary printing the composition onto the fabric.
Claim 16
Dependent Claim
25 words
A method according to claim 6 wherein said step of applying a curable finishing composition comprises coating the composition onto the surface of the fabric.
Claim 17
Independent Claim
122 words
A method for finishing a fabric formed of textile yarns to reduce the size of the interstices between the yarns so as to prevent the penetration of down, fiberfill or other insulating materials, said method comprising applying to the fabric a curable finishing composition comprising a reactive silicone polymer, a crosslinkable durable-press finishing agent, and a starch filler, heating the fabric to dry and cure the finishing composition and form a thin film at the surface of the fabric and bridging between intersecting yarns so as to at least partially fill the interstices between the yarns of the fabric and reduce the permeability of the fabric, and calendering the fabric to flatten the yarns and further reduce the porosity of the fabric.
Claim 18
Independent Claim
122 words
A method for finishing a fabric formed of textile yarns to reduce the size of the interstices between the yarns so as to prevent the penetration of down, fiberfill or other insulating materials, said method comprising applying to the fabric a curable finishing composition comprising a reactive silicone polymer, a crosslinkable durable-press finishing agent, and a starch filler, heating the fabric to dry and cure the finishing composition and form a thin film at the surface of the fabric and bridging between intersecting yarns so as to at least partially fill the interstices between the yarns of the fabric and reduce the permeability of the fabric, and calendering the fabric to flatten the yarns and further reduce the porosity of the fabric.
