Definitions

  • the present invention relates generally to the field of safety apparel, and more specifically to safety garments for use in various environments, including for example environments containing actual or potential radiological, biological, or light-splash hazards, the apparel having, in various embodiments, reduced particulate shedding properties, attachment facilities, reinforced points of wear or contact contamination risk, and ease-of-safe-removal characteristics.
  • Safety garments such as disposable smocks, jumpsuits, gloves, shoe coverings, and hair coverings, are required apparel for the performance of many jobs.
  • Some of the jobs requiring safety garments are performed in clean room environments, wherein the introduction of foreign matter must be minimized.
  • technicians in certain sensitive medical fields dealing with infectious matter, aerospace researchers assembling interplanetary probes, and material scientists developing and manufacturing ultra-pure materials all wear safety garments in clean room environments.
  • the safety garments in some situations perform the dual function of protecting the wearer from the potentially hazardous materials he is working with as well as preventing unwanted matter from the wearer's person from contaminating his work product. In other situations, safety garments protect the worker from exposure to dangerous materials, such as radioactive, chemical, and biological hazards.
  • Safety garments for use in clean room environments are typically made from nonwoven disposable materials, such as from sheets of spunbond/melt blown/melt blown/spunbond (SMMS) material and the like. Such sheets of material are cut into patterns and stitched together to form desired safety apparel.
  • SMMS spunbond/melt blown/melt blown/spunbond
  • Such sheets of material are cut into patterns and stitched together to form desired safety apparel.
  • these garments are intended to be disposable and the focus is on their functionality and not aesthetic appeal, little attention is paid to the hemming and stitching.
  • the "as cut” edges are thus exposed.
  • contaminant levels in the parts per million or even parts per billion would be too high, such exposed cut edges present genuine sources of potential particulate contamination.
  • One aspect of the present disclosure relates to a safety garment.
  • Some embodiments include at least one sheet of nonwoven fabric having at least one cut edge, a plurality of stitches formed in the sheet(s) of nonwoven fabric to define a garment; and hemming formed at cut edges.
  • the nonwoven fabric is preferably formed from spunbond/melt blown material.
  • the stitching is characterized by an optimized stitch density of between 254 and 304,80 stitches per mm (ten and twelve stitches per inch).
  • the garment includes at least one attachment feature for holding or attaching one or more dosimeters to the garment. These may be positioned to allow the wearer to grasp them and tear open certain seams, partially or completely open a zipper, or otherwise remove the garment.
  • the garment also includes an improved neck closure that simplifies donning of the garment and aids the wearer's effort to doff the suit while avoiding self-contamination events.
  • Some embodiments have reinforced knees and elbows for additional protection against contact with hazardous materials.
  • One object of the present invention is to provide an improved safety garment.
  • An object is to facilitate doffing of the garment with a reduced risk of contaminating oneself.
  • Safety garment 10 is formed as a smock.
  • Safety garment 10 is preferably made from spunbond/melt blown/melt blown/spunbond (SMMS) material, spunbond/melt blown/spunbond (SMS) material, or the like, and includes double-folded and hemmed edges 12.
  • the edges 12 are folded such that all cut edges of the non-woven material are double-folded under so as not to be exposed. Non-exposure of the edges 12 thus greatly reduces the potential for generation of shed particles where the material was cut.
  • the seams 16 are stitched with an optimization of the number of stitches per mm (per inch (SPI)), increased to 254-304,8 stitches per mm over the standard 152,4-203,2 stitches per mm (10-12 SPI over the standard 6-8 SPI).
  • Stitch densities of 254-304,8 stitches per mm (10-12 SPI) have been found to be better than the lower range, as densities greater than 304,8 stitches per mm (12 SPI) weaken the non-woven material via excessive perforation and those less than 245 stitches per mm (10 SPI) provide a looser and weaker hem, such that particulate shedding is not minimized.
  • Fig. 3 illustrates a jumpsuit 14 made from spunbond/melt blown/melt blown/spunbond (SMMS) material, spunbond/melt blown/spunbond (SMS) material, or the like.
  • the jumpsuit 14 includes twice-folded and hemmed edges 12. The edges 12 are folded such that all cut edges of the non-woven material are double-folded under so as not to be exposed.
  • the seams 16 are stitched with an increased stitch density of 254-304,8 stitches per mm over the standard 152,4-203,2 stitches per mm (10-12 SPI over the standard 6-8 SPI). Seams are also bound with additional welting or other integrative material to reinforce the seams against contamination.
  • the garment also includes foot coverings 18 that are preferably stitched to the garment but may alternately be individually formed and attached, such as by an elastic band stitched into the hem at the foot opening.
  • the garment 14 further includes an excess of material in the armpit 20 and groin/seat area 22, to minimize the risk of accidental tearing that might generate additional particulate matter that enters into the environment, and might expose the wearer to environmental hazards.
  • the garments 10 and 14 are often made by cutting one or more sheets of nonwoven material into a desired safety garment pattern.
  • Simple patterns e.g., shoe coverings
  • more complex patterns e.g., smocks, jumpsuits, and the like
  • the sheet(s) is/are then stitched together to define a garment 10.
  • the edges of the garment 10 are then hemmed. All cut edges are twice folded and hemmed under to prevent exposure of any cut edges that could increase the likelihood of particulate shedding. All stitching in these illustrative embodiments is characterized by a stitch density in the range of 254-304,8 stitches per mm (10 to 12 stitches per inch).
  • Fig. 4 illustrates garment 24.
  • the garment 24 of Fig. 4 is similar to that described in FIG. 1 , but with the addition of loops 30 affixed to the sleeve 32 portion of the garment 24, to engage a wearer's hands so as to keep the garment 24 positioned about the wearer's body.
  • the safety garment 24 is formed as a smock and is preferably made from spunbond/melt blown/melt blown/spunbond (SMMS) material, spunbond/melt blown/spunbond (SMS) material, or the like.
  • the garment 10 includes double-folded and hemmed edges 12.
  • the edges 12 are folded such that all cut edges of the non-woven material are double-folded under so as to not be exposed. Non-exposure of the edges 12 thus greatly reduces the potential for generation of shed particles where the material was cut.
  • the loops 30 are likewise folded over and stitched such that there are no exposed cut edges.
  • the seams 16 are stitched with an optimization of the number of stitches per per mm, increased to 254-304,8 stitches per mm over the standard 152,4-203,2 stitches per mm (per inch (SPI), increased to 10-12 SPI over the standard 6-8 SPI).
  • Fig. 5 illustrates a jumpsuit 34 similar to that of Fig. 3 with the addition of loops 30 extending from the sleeve portion 32 of the garment 34 to engage the hands of a wearer (similar to Fig. 4 ).
  • the jumpsuit 34 is likewise preferably made from spunbond/melt blown/melt blown/spunbond (SMMS) material, spunbond/melt blown/spunbond (SMS) material, or the like.
  • the jumpsuit 34 includes twice-folded and hemmed edges 12. The edges 12 are folded such that all cut edges of the non-woven material are double-folded under so as to not be exposed.
  • the loops 30 are likewise formed of the SMMS, SMS or the like and folded over and stitched such that the cut edges are not exposed.
  • the seams 16 are stitched with 254-304,8 stitches per mm (10-12 SPI).
  • the garment also includes foot coverings 18 that are preferably stitched to the garment, but may alternately be individually formed and attached, such as by an elastic band stitched into the hem at the foot opening.
  • the garment 12 further includes an excess of material in the armpit 20 and groin/seat area 22, to minimize the risk of accidental tearing that might generate additional particulate matter into the environment as well as expose the wearer to environmental hazards.
  • each loop 30 is preferably formed from an elongated piece of cut nonwoven fabric defining a pair of generally parallel cut edges 12, and wherein the cut edges 12 are folded under and hemmed into place such that the cut edges 12 are not exposed.
  • Fig. 6 illustrates a protective garment 110 for use with a radiation monitoring device
  • the garment 110 is a jumpsuit or coverall-type garment having a hood portion 125 and a body portion 115.

  • the garment includes separate, separable or integrated hand coverings.
  • the garment includes separate, separable, or integrated hoods.
  • the arm openings 155 and the leg openings 156 are hemmed so as to reduce shredding of the garment material.
  • the edges at arm openings 155 and the leg openings 156 are double-folded and hemmed such that all cut edges are double-folded under so as to not be exposed. Non-exposure of the edges greatly reduces the potential for generation of shed particles where the material was cut.
  • the arm openings 155 and/or leg openings 56 further include elastic bands so as to ensure a tight fit.
  • closure means 150 includes a zipper 152.
  • closure means 150 includes snaps, buttons, hook-and-loop closure materials such as Velcro®, adhesive strips, or any other suitable closure means.
  • closure means 150 further includes a cover flap 195 capable of being folded over once opening 146 is closed using zipper 152. Cover flap 195 prevents material from entering garment 110 through zipper 152. Flap 195 is releasably held in the closed position by a securing strip 190, which may comprise hook-and-loop closure materials such as Velcro®, adhesive strips, or any other suitable securing means.
  • Garment 110 can be made from a non-woven material such as polypropylene, polyethylene, polyester materials, and the like, including combinations of two or more non-woven materials. Such materials may be manufactured using spunbond/melt blown/melt blown/spunbond (SMMS) techniques, spunbond/melt blown/spunbond (SMS) techniques, or other suitable techniques for manufacturing non-woven garments, and may include two or more layers of material and/or multiple layers of different materials, as desired.
  • SMMS spunbond/melt blown/melt blown/spunbond
  • SMS spunbond/melt blown/spunbond
  • the seams 116 located at various points about the garment 110 are optionally double-folded under so as not to be exposed.
  • the seams 116 are also stitched with an optimized number of stitches per mm increased to 254-304,8 stitches per mm over 152,4-203,2 stitches per mm (inch (SPI) increased to 10-12 SPI over 6-8 SPI), which is the industry standard.
  • a stitch density of 254-304,8 stitches per mm (10-12 SPI) has been found to be optimal, as more than 304,8 stitches per mm (12 SPI) weakens the non-woven material via excessive perforation and less than 254 stitches per mm (10 SPI) provides a looser and weaker hem, such that particulate shedding is not minimized.
  • seams 16 are formed using some other method such as sonic welding or binding with welting or other materials.
  • garment 110 further includes at least one attachment feature 130 for a dosimeter or other measurement, communication, or detection device.
  • garment 110 includes two attachment features 130 located near the garment shoulders on its front side. The garment includes a greater or lesser number of attachment features positioned at other locations about the garment, such as the arms, wrists, or waist area, as desired.

  • garment 110 includes further monitoring and/or communication devices in addition to dosimeters, such as body temperature monitoring devices, radios, pulse rate monitors, and the like.
  • the garment 110 is constructed such that one or more closures (zippers, adhesives, etc.) are designed to open, rip, or tear when a force above a predetermined threshold is applied.
  • closures zippers, adhesives, etc.
  • Such "tear-open" garments are designed so as to allow for easy removal of a garment when it is no longer needed. Tear-open garments allow workers to quickly, safely, and easily remove a garment at the end of a shift, for example.
  • Attachment features 130 are optionally positioned so as to allow a wearer to grasp one or more of them and strong enough such that pulling on the attachment features 130 causes the tear-open closures to at least begin to open, thereby allowing the worker to quickly, safely, and easily remove the garment 110.
  • a garment 110 according to another embodiment of the disclosed technology will open at the closure means 150 when sufficient force is applied by the wearer to the attachment features 130, thereby allowing the wearer to remove the garment 110.
  • Portions of garment 110 likely to experience wear such as the knees and elbows may include reinforced portions 140, 145 to preclude seepage or bleed-through of contamination in the event the wearer leans or kneels in contaminated environments.
  • Reinforced portions 140, 145 may be made from the same material as garment 110 or from a different, stronger material.
  • garment 110 may be made from two or more layer of material.
