Abstract

Articles, such as tee shirts, and method of making the same are disclosed. An article comprises a main body formed from a p re-shrunk natural fabric; and a wicking barrier printed on a first surface of the fabric in a pattern that defines adjacent printed and unprinted portions such that moisture adjacent the first surface of the fabric is cause to move to the unprinted portions and is absorbed through the fabric.

Description

ARTICLE COMPRISING A NATURAL FABRIC AND A PATTERNED WICKING BARRIER

FIELD

[0001] The present disclosure relates to an article such as a tee shirt. More particularly, the tee shirt may be constructed in such a way as to provide durability, measurable moisture

management, and wearer comfort.

BACKGROUND

[0002] In the state of the art, various tee shirts sacrifice comfort or fit in an attempt to improve moisture management. Alternatively or additionally, conventional tee shirts may use synthetic materials and yams in construction. However, improvements are needed.

SUMMARY

[0003] The present disclosure relates to articles of clothing such as tee shirts.

[0004] Articles, such as tee shirts, and method of making the same are disclosed. An article may comprise a main body formed from a pre-shrunk natural fabric; and a wicking barrier printed on a first surface of the fabric in a pattern that defines adjacent printed and unprinted portions such that moisture adjacent the first surface of the fabric is cause to move to the unprinted portions and is absorbed through the fabric.

[0005] There has thus been outlined, certain embodiments of the present disclosure in order that the detailed description thereof herein may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional embodiments of the invention that will be described below and which will form the subject matter of the claims appended hereto.

BRIEF DESCRIPTION OF THE DRAWINGS

[0006] In order to facilitate a fuller understanding of the invention, reference is now made to the accompanying drawings, in which like elements are referenced with like numerals. These drawings should not be construed as limiting the invention and intended only to be illustrative.

[0007] FIG. 1 is a chart of comparative data of conventional articles comprising examples A-K.

[0008] FIG. 2 is a chart of comparative data of conventional articles comprising examples A-K. DETAILED DESCRIPTION

[0009] An article of clothing such as a tee shirt is described.

Materials

[0010] An article in accordance with the present disclosure may be formed from natural fibers. The article may be formed from a material comprising cotton (e.g., long fiber cotton, Supima cotton, etc.). Reference to long fiber cotton may comprise extra-long staple cotton and/or may comprise cotton having an average fiber length of greater than 1 inch, greater than 1.1 inches, greater than 1.2 inches, greater than 1.3 inches, greater than 1.4 inches, greater than 1.5 inches, greater than 1.6 inches, greater than 1.7 inches, greater than 1.8 inches, greater than 1.9 inches, or greater than 2 inches. The article may be formed from a material consisting essentially of cotton (e.g., long fiber cotton, Supima cotton, etc.). The article may be formed from a material consisting of cotton (e.g., long fiber cotton, Supima cotton, etc.).

[0011] Materials for forming articles in accordance with the present disclosure may be processed using various spinning techniques. Fibers may be spun using a conventional spinning technique. Fibers may be spun using ring or open-end spinning. Alternatively, fibers may be spun using an air entanglement (e.g., air jet) processes such as spinning. Such air entanglement may cause short fibers to fall out leaving longer fibers in the yam.

[0012] In an aspect, when yarn is knitted into a fabric, a pre-shrink process may include compacting the fabric to effectively increase the g/cm^A2 of the pre-compacted-fabric.

[0013] The fabric may be processed in a wet tumbling and/or dry tumbling processes. The fabric/garment may be pre-shrunk such that a shrinkage rate at the garment level is below 2% or below 1%.

[0014] The fibers’ yam and resultant fabric of the present disclosure may provide increased fabric strength, low fabric torque effect, and/or higher resistance to shrinkage and pilling.

Wicking

[0015] Fabric in accordance with the present disclosure may be printed with wicking patterns (for example, which may comprise Wicking Windows™ technology by Cotton Incorporated). As an example, a wicking barrier may be printed on the skin-facing side of the fabric. The printed barrier may define a patern of non-absorbent barrier portions disposed adjacent unprinted absorbent fabric portions. As the wearer begins to sweat, the printed areas remain dry against the skin while small absorbent“windows” pull moisture to the outside of the fabric where it can evaporate and dry quickly. The print pattern may be a simple coverage effect or can incorporate a stylized design, which adds a greater level of versatility to the functional performance. As an example, a waffle pattern may be used such that the interior diamonds are printed, while the interposed latice are unprinted. As such, moisture is forced to the lattice and is pulled to the fabric for faster expansion and evaporation. Other patterns may be used.

Construction

[0016] An article such as a tee shirt may be constructed in accordance with the present disclosure. Such construction may comprise a side seam overlock. The construction may comprise a bound seam interior seam allowance at shoulder. The construction may comprise a double bound collar. The construction may comprise minimized exterior topstitching at structural seams (e.g., to avoid abrasion). Conventional closing is under-arm, but articles in accordance with the present disclosure may comprise a construction that closes the arm hole last. Other construction methods may be used.

[0017] Performance of example articles (tee shirts) in accordance with the present disclosure was compared to conventional articles. Performance of conventional articles labeled examples A-K are shown in FIGS. 1-2. By comparison, example articles of the present disclosure were produced and tested, demonstrating improved performance over the conventional articles of FIGS. 1-2. As an illustrative example, several articles were produced in accordance with the present disclosure and exhibited the following example characteristics:

[0021] The above examples 1-3 are non-limiting and presented for illustration only. As shown, the present disclosure may produce articles exhibiting improved durability over conventional articles. For example, an article may comprise a main body formed from a pre-shrunk natural fabric; and a wicking barrier printed on a first surface of the fabric in a pattern that defines adjacent printed and unprinted portions such that moisture adjacent the first surface of the fabric is cause to move to the unprinted portions and is absorbed through the fabric. As a further example, forming an article in accordance with the present disclosure may comprise a combination of fiber length (e.g., long staple cotton) and spinning technique (e.g., air entanglement).

Such an article may exhibit one or more of the following characteristics:

one-way transport index >200 when tested using Moisture Management Test (MMT) method AATCC TM 195; and/or

<10 seconds drop absorbency speed when tested using Drop Absorbency method

For example, an article may comprise a main body formed from a pre shrunk natural fabric; and a wicking barrier printed on a first surface of the fabric in a pattern that defines adjacent printed and unprinted portions such that moisture adjacent the first surface of the fabric is cause to move to the unprinted portions and is absorbed through the fabric. As a further example, forming an article in accordance with the present disclosure may comprise a combination of fiber length (e.g., long staple cotton) and spinning technique (e.g., air

entanglement). Articles in accordance with the present disclosure may show improved characteristics such as:
