Abstract
Abstract A process for producing a durable textile fabric, for use as a bed blanket and the like, from a nonwoven spunlaced material by application of a fibrous substance to at least one side of the spunlaced material by flocking techniques is disclosed. The spunlaced nonwoven which is utilized comprises a nonwoven fabric having a fiber entanglement completeness of at least 0.5, and being preferably formed from polyester fibers having average fiber lengths of between 1/4 inch and 5 inches with an average fiber denier of about 0.50 to 20. An adhesive material is first applied to the spunlaced substrate, then the flocking fibers, having a denier of about 0.5 to 10 and a length or mixture of lengths ranging from 0.5 to 8 mm, are applied using conventional techniques. The resulting product, functionally sound and lightweight, is also described.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
29 words
The process of claim 1 comprising applying the adhesive in a continuous manner in an amount from about 0.9 to about 1.5 ounces per square yard of the substrate.
Claim 2
Dependent Claim
23 words
The process of claim 1 including the additional step of allowing the flocked, adhesive coated substrate to dry and then curing the adhesive.
Claim 3
Dependent Claim
28 words
The process of claim 1 wherein the flock fibers have a length of from about 0.5 to 8 mm and a denier from about 0.5 to about 10.0.
Claim 4
Dependent Claim
29 words
The process of claim 4 wherein the flock fibers of a length of from about 1 to about 6 mm and a denier from about 1 to about 6.
Claim 5
Dependent Claim
19 words
The process of claim 1 wherein the nonwoven spunlaced substrate has a fiber entanglement completeness of at least 0.5.
Claim 6
Dependent Claim
20 words
The process of claim 1 wherein the fiber entanglement frequency of the spunlaced substrate is at least 20 per inch.
Claim 7
Dependent Claim
40 words
The process of claim 1 wherein the nonwoven spunlaced substrate is made of polyester fibers having an average fiber length of between 1/4 inch and 5 inches, and having an average denier of about 0.50 to 20 denier per filament.
Claim 8
Dependent Claim
11 words
The process of claim 8 wherein the polyester is polyethylene terephthalate.
Claim 9
Dependent Claim
26 words
The process of claim 1 wherein the nonwoven spunlaced substrate consists essentially of a major amount of polyester fibers and a minor amount of cellulosic fibers.
Claim 10
Dependent Claim
57 words
The process of claim 1 including the additional steps of: coating the adhesive onto the other surface of the substrate; distributing the flock fibers evenly over the thus applied adhesive coating before the adhesive sets in an arrangement substantially perpendicular to the substrate; anD allowing the flocked, adhesive coated substrate to dry and then curing the adhesive.
Claim 11
Dependent Claim
13 words
The process of claim 11 wherein said textile comprises a blanket product fabric.
Claim 12
Dependent Claim
124 words
In the process for preparing a soft, resilient nonwoven material comprising applying an adhesive to the first surface of the substrate, the adhesive of a viscosity such that when applied to the surface of the substrate it will remain on the thus coated surface of the substrate; applying flock fibers evenly over the adhesive coated first surface of the substrate before the adhesive sets; and allowing the adhesive to set; applying the adhesive to the second surface of the substrate; applying flock fibers evenly over the thus coated second surface of the substrate before the adhesive sets; and allowing the adhesive to set; the improvement wherein the substrate is a spunlaced nonwoven material and the resulting product is improved in drapeability and reduced bulk.
Claim 13
Dependent Claim
45 words
A durable textile fabric formed from a non-woven material comprising a spunlaced nonwoven substrate having on at least one side thereof an adhesive and flock fibers distributed over and secured to said adhesive, the flock fibers standing substantially perpendicular to the surface of the substrate.
Claim 14
Dependent Claim
21 words
The durable textile product of claim 14 wherein the nonwoven substrate material has a fiber entanglement completeness of at least 0.5.
Claim 15
Dependent Claim
43 words
The durable textile product of claim 14 wherein the nonwoven spunlaced substrate is formed from polyester fibers having an average fiber length of between 1/4 inch and 5 inches, and having an average fiber denier of about 1.0 to 3.0 denier per filament.
Claim 16
Dependent Claim
13 words
The durable textile product of claim 14 wherein the polyester is polyethylene terephthalate.
