Description

RELATED APPLICATIONS

This application claims the benefit of the following four U.S. Provisional Patent Applications, all of which are incorporated by reference:
1. Ser. No. 62/096,959, filed on Dec. 26, 2014;
2. Ser. No. 62/147,831, filed on Apr. 15, 2015;
3. Ser. No. 62/154,181, filed on Apr. 29, 2015; and
4. Ser. No. 62/166,165, filed on May 26, 2015.

FIELD OF THE DISCLOSURE

The present disclosure relates generally to improved medical blankets designed for use by patients in a hospital. In this application, “blanket” includes any type of textile that provides protection against the elements and “hospital” includes any type of medical facility. The improved blankets may be branded as the Eco Blanket Solution™.

BACKGROUND

Hospital blankets for patient use must meet a number of requirements to satisfy the needs of the patient, the hospital and the laundry facility that cleans the blankets. For the patient, the blanket must be sanitary and comfortable, keeping the patient warm in a colder climate and cool in a warmer climate. For the hospital, the blanket must have minimal bulk, be easily portable, be easily distributable to patients for use and be easily collectable from patients for cleaning or disposal. For the laundry facility, the blanket must be easy to clean with minimal water/soap usage and minimal drying times.
Traditional cotton and polyester/cotton thermal blankets often do not satisfy these needs because of their numerous drawbacks. Such drawbacks include: poor warmth due to low thermal insulation, low strength and abrasion resistance, high water usage in laundering and longer drying time. This results in a blanket with shorter useful life and a relatively higher cost per usage.
Further, optimization in laundry industry has traditionally focused on improved machines, improved chemistry and improved water usage. Yet the state of the art ignores another equally important method of optimization: to improve throughput and profit margins at a laundry by improving the features of the laundered materials.
Accordingly, there is a need in the art to provide an improved hospital blanket that has a longer useful life while providing superior features for the patient, hospital and laundering facility.

I. Improved Polypropylene Blanket
The improved polypropylene blanket provides longer life and low cost per usage due to its high thermal insulation, high strength and high abrasion resistance. This results in a blanket with a fast drying time that conserves energy and proves more durable than cotton-rich products. The blanket is soil resistant that attracts less dirt and dust, is resistant to fungi, molds and mildew and wicks away perspiration from the skin.
A. Physical Properties
The overall properties of the improved polypropylene blanket may include:
Size: 74″×100″ and weight: 2.60 lbs. per blanket (but the size may be adjusted to be any useful length and width and the weight will change accordingly).
Appearances: Choice of white or color; and
Texture: “Chevron” weave pattern, as shown in detail in FIG. 2.
Specific features of the improved polypropylene blanket may include:
Fiber Identification: 100% Olefin,
Fabric weight (ASTM D3776): 6.94 oz./sq. yd.
Fabric count (ASTM D3775): 36.7 ends/inch×30 pics/inch.
Yarn size (ASTM D1059): 775.3 denier warp×747.1 denier filling.
Filament count: 160 filaments warp and 160 filaments filling.
Yarn twist (ASTM D1423):

Singles, “S” twist with 4.08 TPI Avg. (warp); and
Singles “S” twist with 3.94 TPI Avg. (filling).

Thermal transmittance of materials (ASTM F1868): resistance: Rct (CLO) of 0.681 average (Procedure Part A Thermal Resistance)
Electrostatic Clinging of Fabrics, Fabric-to-Metal Test (AATC 115) at 23 degrees C., 42% relative humidity: Warp: 4 seconds for nylon rubbing fabric; 8 seconds for polyester rubbing fabric. Filling: 11 seconds for nylon rubbing fabric; 12 seconds for polyester rubbing fabric. (Average time required for specimen to lose electrostatic charge.)
Fabric Dimensional Change and Appearance (Machine Wash @ 160 degrees F., Tumble Dry High, Unrestored):

First Cycle Dimensional Change: −1.3% Length; −1.2% Width. Appearance: Slightly to negligibly yellower and less bright shade change, No noticeable pilling or fuzzing, Hand is slightly to negligibly more soft. No other noticeable change or deterioration.
Third Cycle Dimensional Change: −2.1% Length; −2.1% Width. Appearance: Slightly yellower and less bright shade change. No noticeable pilling or fuzzing. Hand is slightly to negligibly more soft. Slight to negligible short snags No other noticeable change or deterioration.
Fifth Cycle Dimensional Change: −2.3% Length; −2.6% Width. Appearance: Noticeably yellower and less bright shade change, No noticeable pilling or fuzzing. Hand is slightly more soft. Slight to noticeable short snags, No other noticeable change or deterioration.

The foregoing features may be adjusted so as to produce results similar to those described herein.
B. Advantages
The advantages of the improved polypropylene blanket are numerous. For the patient, the improved polypropylene blanket wicks away perspiration by promoting movement of moisture away from the skin because of its hollow fiber. This increases patient comfort because it allows the fabric to stays cooler in a warm climate. In a colder climate, the hollow fiber provides additional insulation, which keeps the patient warm.
The improved polypropylene blanket is also more sanitary due to its resistant to fungi, molds and mildew. This resistance inhibits growth of microscopic organisms on the surface and resists growth of odor producing bacteria. Polypropylene is also soil resistant attributable to chemical inertness and lower accumulation of static by friction during use. As a result, polypropylene fabric attracts less dirt and dust as compared to other materials.
For the hospital and laundry, the improved polypropylene blanket has minimal bulk and is easily portable. The improved polypropylene blanket also cleans easily with low water usage and quick drying when laundering. As such, it uses less energy, utilities and chemicals to process. This provides a cost savings both because it takes fewer resources to clean each blanket and because each blanket can endure more laundry cycles before needing disposal.
C. Test Results
Various test results of the improved polypropylene blanket when compared with standard CVC thermal blankets show marked improved performance in the throughput of the blanket's washing and drying. (CVC stands for Chief Value Cotton, which is a blend of cotton and polyester where cotton is in the majority.)

EXAMPLE 1

Example 1 is based on a 5-cycle laundry tunnel wash and drying test comparing a 2.62-pound improved polypropylene blanket (a “new spread”) and a 2.2-pound CVC thermal blanket (a “light-weight spread”). A cycle is a tunnel wash and dry. The therm is a unit of heat energy equal to 100,000 British thermal units (BTU) It is approximately the energy equivalent of burning 100 cubic feet (often referred to as 1 CCF) of natural gas. One therm can also be provided by about 96.7 cubic feet (2.74 m³) of natural gas.
The following Table 1 shows information related to a 5-cycle wash for the new spread.

EXAMPLE 4

Shown in Table 10 are data comparing results after about 60 pieces of the improved polypropylene blanket (called ECO-Blanket) and a prior art standard blanket (called E49277-621) were washed 100 times.

The data show that because of the lower absorbency level of the yarns, only about ⅓ as much water ends up going into the dryer. There is a corresponding ⅔ reduction in drying time.
D. Conclusions
The conclusions drawn from these Examples are:
The improved polypropylene blanket inherently absorbs less water when compared to regular CVC thermal blankets. CVC thermal blankets absorb 150% water with respect to their own weights and the improved polypropylene blanket absorbs only 36% of its weight.
Laundry machines operating at optimum workload are able to launder 50% more improved polypropylene blankets due to its less absorption. This means less water usage and waste, less chemicals, less wash detergents and higher efficiency per machine.
The improved polypropylene blankets are quick to dry. In line drying, the improved polypropylene blanket dry 6 times faster than regular CVC thermal blankets. In tumble drying, the improved polypropylene blanket needs 75% less tumble drying time than regular CVC thermal blankets.
In addition to the foregoing specifications, a 1.6 to 1.75 pound plain weave blanket may be used with otherwise the same or similar physical properties, This plain-weave blanket may be a bath blanket with the same 100% Olefin.
II. Improved Polypropylene/Polyester Blanket
The improved polypropylene/polyester blanket is a second embodiment of a blanket that provides longer life and low cost per usage due to its high thermal insulation, high strength and high abrasion resistance. This results in a blanket with a fast drying time that conserves energy and proves more durable than cotton-rich products. The blanket is soil resistant that attracts less dirt and dust, is resistant to fungi, molds and mildew and wicks away perspiration from the skin.
The improved polypropylene/polyester blanket may have one or more of the following physical properties:
Blend: 85% Polypropylene/15% Polyester.
Finished Size: 70″ width×90″ length and weight 1.6 lb. (but the size may be adjusted to be any useful length and width and the weight will change accordingly).
Warp Count: 150 Denier.
Weft Count: 330 Denier.
Warp Threads per inch: 34.
Weft Threads per inch: 34.
Packing Bale: 48 pcs per bale.
Fabric weight (ASTM D3776): 4.66 oz./sq. yd.
Fabric count (ASTM D3775): 36.0 ends/inch×40.0 pics/inch.
Yarn size (ASTM D1059): 145.6/1 denier warp×738.7/2 denier filling.
Filament count: 48 filaments warp and 80 filaments filling per ply.
Yarn twist (ASTM D1423):

<1 TPI (warp); and
2 Ply “S” twist with 199.6 TPI Avg. (filling).

Fiber Identification (AATCC 20A-With Moisture): Olefin: 83.91% (confirmed by DSC analysis) and Polyester: 16.09%.
Thermal transmittance of materials (ASTM F 1868): resistance: Rct (CLO) of 0.67 average (Procedure Part A Thermal Resistance).
Electrostatic Clinging of Fabrics, Fabric-to-Metal Test (AATC 115) at 23 degrees C., 27% relative humidity: Wales: 0 seconds for nylon rubbing fabric; 0 seconds for polyester rubbing fabric. Courses: 0 seconds for nylon rubbing fabric; 0 seconds for polyester rubbing fabric. (Time required for specimen to lose electrostatic charge: fabric does not cling.)
Fabric Dimensional Change and Appearance (Machine Wash @ 160 degrees F., Tumble Dry High, Unrestored):

First Cycle Dimensional Change: −15.5% Length; −3.9% Width. Appearance: Slightly brighter shade change. No noticeable pilling. Slight to negligible fuzzing, Slightly puckered overall. Hand is slightly to negligibly less soft. Slight to negligible short snags. No other noticeable change or deterioration.
Third Cycle Dimensional Change: −17.5% Length; −5.1% Width. Appearance: Slightly brighter shade change. No noticeable pilling. Slight fuzzing, Slightly puckered overall. Hand is slightly less soft. Slight short snags. No other noticeable change or deterioration.
Fifth Cycle Dimensional Change: −17.9% Length; −5.5% Width. Appearance: Slightly brighter shade change. No noticeable pilling. Slight fuzzing, Noticeably puckered overall. Hand is slightly less soft. Slight short snags. No other noticeable change or deterioration.

In an additional test, after 3 washes, the length shrank by 20% and the width shrank by 5%. These washes produced a yellowed fabric with a rough hand, stretches and rough wavy edges.
The foregoing features may be adjusted so as to produce results similar to those described herein. Specifically, a second embodiment may have a fabric weight of 6.82 to 7.2 oz/sq. yd. and a fabric count within a range of 35-40/″ ends×30-34/″ pics.
The improved polypropylene/polyester blanket may have the same advantages as the improved polypropylene blanket set forth in Section I. D, above.
