Abstract
Abstract Fabric suitable for the manufacture of rental shirts that are capable of being industrially laundered are made by air jet spinning an intimate blend of about 50--50 polyester/cotton (having wrapper fibers holding the yarn bundle together), vat dyeing the cotton component of the yarn (and disperse dyeing the polyester component), and then knitting the dyed yarn to produce a fabric with tightly formed stitches. The yarn is also preferably scoured and finished prior to knitting. The knit fabric is preferably made into a rental shirt or like garment, the fabric having a maximum shrinkage of about 8% both in length and width unrestored after five wash and tumble dry sequences per AATCC Test Method 135, a colorfast rating of 4.0 or higher when subjected to AATCC Test Method 61-IIA, has a rating of 4.0 or higher when tested for pilling, and a life expectancy of at least 50 industrial laundering wash-dry-wear cycles.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
88 words
A method of producing a fabric for use as a garment being industrially laundered, comprising the steps of substantially sequentially: (a) air jet spinning an air jet spun intimate polyester/cotton blend yarn, having wrapper fibers holding the yarn bundle together; (b) vat dyeing the cotton component of the air jet spun yarn with vat dye, and dyeing the polyester component; and (c) knitting the dyed yarn into a fabric for use in the production of a rental shirt being industrially launderable for at least 50 wash-and-wear laundry cycles.
Claim 2
Independent Claim
88 words
A method of producing a fabric for use as a garment being industrially laundered, comprising the steps of substantially sequentially: (a) air jet spinning an air jet spun intimate polyester/cotton blend yarn, having wrapper fibers holding the yarn bundle together; (b) vat dyeing the cotton component of the air jet spun yarn with vat dye, and dyeing the polyester component; and (c) knitting the dyed yarn into a fabric for use in the production of a rental shirt being industrially launderable for at least 50 wash-and-wear laundry cycles.
Claim 3
Dependent Claim
25 words
A method as recited in claim 1 comprising the further steps, after step (c), of: (d) scouring the knit fabric, and (e) finishing the fabric.
Claim 4
Dependent Claim
25 words
A method as recited in claim 2 wherein step (e) is practiced to impart soil release, wrinkle reduction, and shrinkage resistance properties to the fabric.
Claim 5
Dependent Claim
51 words
A method as recited in claim 3 wherein step (e) is practiced using a first pass using substantially only hot water, and a second pass using a finish formula containing a glyoxal-based resin, a polyethylene slightly cationic softener, a non-ionic alcohol ethoxyolate wetting agent, and a non-ionic fluorochemical stain release agent.
Claim 6
Dependent Claim
28 words
A method as recited in claim 3 wherein step (d) is practiced to remove any residues left on the yarn after the practice of steps (b) and (c).
Claim 7
Dependent Claim
20 words
A method as recited in claim 5 wherein step (c) is practiced to knit the fabric with tightly formed stitches.
Claim 8
Dependent Claim
22 words
A method as recited in claim 6 wherein step (c) is further practiced to produce a pique or a jersey fabric construction.
Claim 9
Dependent Claim
24 words
A method as recited in claim 1 wherein step (a) is practiced to produce a substantially 50--50 intimate polyester/cotton blend air jet spun yarn.
Claim 10
Dependent Claim
31 words
A method as recited in claim 8 wherein steps (a) through (c) are practiced to produce a fabric having a finished fabric weight of 9 to 11 ounces per linear yard.
Claim 11
Dependent Claim
25 words
A method as recited in claim 1 comprising the further step (a'), between steps (a) and (b), of winding the undyed yarn onto dye packages.
Claim 12
Dependent Claim
47 words
A method as recited in claim 10 wherein step (b) is practiced using vat black 16, vat brown 1, vat green 1, vat green 3, vat red 13, vat yellow 2, or vat blue 55 dye, for the cotton component, and disperse dye for the polyester component.
Claim 13
Dependent Claim
29 words
A method as recited in claim 1 wherein step (b) is further practiced using disperse dye for the polyester component at the same time as vat dyeing takes place.
Claim 14
Dependent Claim
18 words
A method as recited in claim 1 comprising the further step of making the knit fabric into shirts.
Claim 15
Dependent Claim
31 words
A method as recited in claim 1 wherein steps (a) through (c) are practiced to produce a fabric having a finished fabric weight of 9 to 11 ounces per linear yard.
Claim 16
Dependent Claim
82 words
A garment being industrially launderable, produced by the steps of substantially sequentially: (a) air jet spinning an air jet spun intimate polyester cotton blend yarn, having wrapper fibers holding the yarn bundle together; (b) vat dyeing the cotton component of the air jet spun yarn with vat dye, and also dyeing the polyester component; (c) knitting the dyed yarn into a fabric; and (d) making the fabric into a garment having a life expectancy of at least 50 industrial laundering wash-dry-wear cycles.
Claim 17
Dependent Claim
82 words
A garment being industrially launderable, produced by the steps of substantially sequentially: (a) air jet spinning an air jet spun intimate polyester cotton blend yarn, having wrapper fibers holding the yarn bundle together; (b) vat dyeing the cotton component of the air jet spun yarn with vat dye, and also dyeing the polyester component; (c) knitting the dyed yarn into a fabric; and (d) making the fabric into a garment having a life expectancy of at least 50 industrial laundering wash-dry-wear cycles.
Claim 18
Dependent Claim
32 words
A garment as recited in claim 15 wherein the garment is made by the further steps, between steps (c) and (d), of: (e) scouring the knit fabric, and (f) finishing the fabric.
Claim 19
Dependent Claim
