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.
Claims14
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.
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.
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.
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.
