Abstract

One aspect of the invention provides a washable and dry-cleanable knit garment having a permanent pleat. The washable and dry-cleanable knit garment includes: a cotton-polyester blend knit fabric comprising at least 50% cotton; fusible interfacing fused to an interior surface of the cotton-polyester blend knit fabric to form a fabric-fusible assembly; and at least one permanent pleat formed in the fabric-fusible assembly. Another aspect of the invention provides a method of manufacturing a washable and dry-cleanable knit garment having a permanent pleat. The method includes: providing a cotton-polyester blend knit fabric comprising at least 50% cotton; applying fusible interfacing fused to an interior surface of the cotton-polyester blend knit fabric to form a fabric-fusible assembly; forming one or more pleats in the fabric-fusible assembly; and activating the fusible with a heat press.

Description

BACKGROUND OF THE INVENTION

Pleats are used in clothing to gather a wide piece of fabric to a narrower circumference (e.g., for aesthetic reasons). Although cotton is a popular fabric (e.g., due to comfort and flexibility), it has been historically believed that cotton fabrics cannot be pleated, particularly in a manner that is feasible for production and wear.

SUMMARY OF THE INVENTION

One aspect of the invention provides a washable and dry-cleanable knit garment having a permanent pleat. The washable and dry-cleanable knit garment includes: a cotton-polyester blend knit fabric comprising at least 50% cotton; fusible interfacing fused to an interior surface of the cotton-polyester blend knit fabric to form a fabric-fusible assembly; and at least one permanent pleat formed in the fabric-fusible assembly.
This aspect of the invention can have a variety of embodiments. The cotton-polyester blend knit fabric can include between 49% and 20% polyester. The cotton-polyester blend knit fabric can include between 40% and 30% polyester. The cotton-polyester blend knit fabric can further include spandex.
The permanent pleat can be reinforced with stitching.
Another aspect of the invention provides a method of manufacturing a washable and dry-cleanable knit garment having a permanent pleat. The method includes: providing a cotton-polyester blend knit fabric comprising at least 50% cotton; applying fusible interfacing fused to an interior surface of the cotton-polyester blend knit fabric to form a fabric-fusible assembly; forming one or more pleats in the fabric-fusible assembly; and activating the fusible with a heat press.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention enable pleats in garments such as a T-shirt, which is unusual, and enable a relaxed feel with substantive and tailored design elements.

Washable and Dry-Cleanable Knit Garment Having a Permanent Pleat

Referring to FIGS. 1A-1C, washable and dry-cleanable knit garment 100 includes a cotton-polyester blend knit fabric 102 and fusible interfacing 104 fused to an interior surface of the cotton-polyester blend knit fabric to form a fabric-fusible assembly 106. At least one permanent pleat 108 is formed in the fabric-fusible assembly 106. The relative dimensions of the garment 100 may be exaggerated for ease of illustration and understanding and the permanent pleat 108 and the fabric-fusible assembly 106 may lie substantially flat or in-plane relative to each other.
The content of the cotton-polyester blend knit fabric 102 can be determined by testing and specified in terms of mass, e.g., by the manufacturer of the cotton-polyester blend knit fabric 102. In some embodiments, the cotton-polyester blend knit fabric 102 has a cotton content of at least 50%, at least 60%, at least 70%, and the like. Exemplary cotton-polyester blend knit fabrics include 50/50 and 65/35 cotton-polyester blends. In some embodiments, the balance of the cotton-polyester blend knit fabric 102 consists substantially or exclusively of polyester. In other embodiments, additional fibers can be added (e.g., spandex, rayon, and the like). For example, the cotton-polyester blend knit fabric 102 could be 52% cotton, 34% polyester, and 14% spandex.
In some embodiments, the cotton-polyester blend knit fabric 102 can have a minimum amount of polyester, e.g., 20%. In some embodiments, the cotton-polyester blend knit fabric 102 includes between 49% and 20% or between 40% and 30% polyester.
Fusible interfacing 104 can be a textile having a heat-activated adhesive on one side. Fusible interfacing 104 can be affixed to the cotton-polyester blend knit fabric 102 using heat and moderate pressure, e.g., with a hand iron, a heat press, and the like. For example, the fusible interfacing 104 can be affixed to the cotton-polyester blend knit fabric 102 to form the fabric-fusible assembly 106 before the pleat 108 is formed. The garment 100 (particularly the pleat 108 can then be heated. Exemplary fusible interfacing includes CX11 available from STC-QST of Los Angeles, Calif., which is sufficiently thin so as to be imperceptible by sight or touch.
The permanent pleat 108 can optionally be reinforced with stitching 110. In some embodiments, the pleat edge is also hemmed to prevent unravelling of the fabric-fusible assembly 106. The stitching can 110 can run the length of (e.g., parallel with) the permanent pleat 108 (e.g., a running or baste stitch) or can be at one or more ends.
The permanent pleat 108 can be three-ply as depicted in FIG. 1B (e.g., at the origin of a flared pleat such as the shoulder of a sleeve) or two-ply as depicted in FIG. 1C (e.g., at the end of a flared pleat such as the distal end of a sleeve).

Method for Manufacturing a Knit Garment Having a Permanent Pleat

Referring to FIG. 2 , a method 200 of manufacturing a washable and dry-cleanable knit garment having a permanent pleat includes providing a cotton-polyester blend knit fabric comprising at least 50% cotton (S202); applying fusible interfacing fused to an interior surface of the cotton-polyester blend knit fabric to form a fabric-fusible assembly (S204); forming one or more pleats in the fabric-fusible assembly (S206); activating the fusible with a heat press (S208); and optionally reinforcing the pleat with one or more stitches (S210).
The applying step (S204) can include heating the fusible to activate the adhesive. In some embodiments, the cotton-polyester blend knit fabric 102 and the fusible interfacing 104 are block-fused together before a pattern for the garment to contain the pleat 108 is cut.
A variety of parameters can be utilized depending on particular combinations of cotton-polyester blend knit fabric 102 and fusible interfacing 104. In one embodiment, the fabric-fusible assembly 106 is heated for 10 seconds in a heat press set to 300° F. (˜150° C.). Suitable heat presses are available under the MPRESS® trademark from eNetShops, LLC of Fullerton, Calif. The pressure applied is generally dictated by the particular heat press. Without being bound by theory, Applicant believes that typical pressures on the order of about 40 pounds-force (˜180 N)
