Sanitary Goods

Films that are used in disposable applications including, e.g., personal hygiene, should be highly permeable to water vapor and should exhibit a good softness. The permeability to water vapor is sometimes referred to breathability 

Compositions have been developed that include a biodegradable aliphatic-aromatic copolyester, i.e., poly(tetramethylene adi-pate-co-terephthalate) and a plasticizer. The composition exhibits a moisture vapor transmission rate of at least 400 (1). 

The plasticizer is selected from esters of citric acid or benzoic acid. Further a tackifying resin can be added. The tackifier may be a rosin derivative, a terpene derivative, poly(lactic acid), or poly(hydroxy-valerate butyrate) (1). 

A material used in sanitary hygiene goods should fulfill the following conditions (2)  

No water solubility to cause absorption of moisture in air during storage to become sticky

Olefin fiber is an important material for nonwovens (77). The geotextile market is stiU small, despite expectations that polypropylene is to be the principal fiber in such appHcations. Disposable nonwoven appHcations include hygienic coverstock, sanitary wipes, and medical roU goods. The two competing processes for the coverstock market are thermal-bonded carded staple and spunbond, both of which have displaced latex-bonded polyester because of improved strength, softness, and inertness. 

The physical properties of the reinforced polyester product made from chopped glass are Hsted in Table 1. The chemical resistance varies according to the composition but is generally good. Its principal uses in building products are for sanitary ware, eg, tub-shower units, and for panels, especially translucent or cement-filled types for roofing and walls of commercial or industrial buildings. 

Various elastic elements are added to disposable sanitary products. Strands of lycra, natural rubber, polyurethane foam, and other elastic laminates are applied to provide good fit and avoid leakage. These are attached with adhesives. While non-PSA formulas such as polybutene-based [64] and polyamide [65] adhesives have shown utility, as well as benefits in terms of resistance to baby oils and lotions, adhesives based on styrenic block copolymers still dominate. SBC-based... 

The hazardous waste standard requires employers to make certain that when showers are a necessary step in the decontamination process, their employees shower at the end of their work shift and when leaving the hazardous waste site. Sanitation-related showers (unlike decontamination showers) are understood to be voluntary. Decontamination and emergency showers should be located close to the worksite. Sanitary showers may be located at some distance from the worksite. A statement in the safety plan encouraging good personal hygiene and daily showers is a good idea. In addition, workers should be encouraged to shower daily even if no shower is available at the worksite. 

Pressure vessels and appurtenances should be constructed of stainless steel or other corrosion-resistant materials. Ideally, these steam generators should receive hot demineralized FW to minimize chemical treatment requirements. Alternatively, where a main boiler plant is installed, 100% steam condensate provides a good source of FW. In practice, it is very difficult to accurately control the correct amount of chemical feed. Chemicals are typically restricted to potable grade, deposit control agents such as polyacrylates, and other materials listed under the Code of Federal Regulations, CFR 21 173.310, or National Sanitary Foundation (NSF International) approval system. These boilers may be electrically heated or gas-fired. 

Lower-density E-plastomers have found alternate use in cast film processes to make elastic film laminates with good breathability which contain laminates of liquid impermeable extensible polymeric films with extensible-thermoplastic-polymer-fiber nonwovens and nonwoven webs of polyethylene-elastomer fibers as the intermediate layers. The development relates to a breathable film including an E-plastomer and filler that contributes to pore formation after fabrication and distension of the film. The method and extent of distension is designed to produce a breathable film by stretching the film to form micropores by separation of the film of the E-plastomer from the particulate solids. This film is useful for manufacture of absorbent personal-care articles, such as disposable diapers and sanitary napkins and medical garments. In detail, these constructions comprise a liquid impermeable extensible film comprising polyolefins. The outer layer contains extensible-thermoplastic-polymer-fiber nonwovens, and an elastic intermediate layer contains nonwoven webs of fiber E-plastomers. The intermediate layer is bonded to the film layer and the outer... 

Inspection and testing of the storm/lndustrlal and sanitary sewers In the area Indicated the sewers were In good condition and only minor amounts of leakage were occurring. Nevertheless, minor repairs were performed. 

Good personal hygiene and proper disposal of sanitary waste are required to prevent the fecal-oral transmission of the hepatitis A virus. 

Hepatitis E is similar to hepatitis A in that the mode of transmission is via the fecal-oral route. Therefore, the most effective ways to prevent acquiring the virus are good personal hygiene and proper disposal of sanitary waste. Frequent handwashing and avoiding contaminated foods and vegetables decrease the risk of infection. 

Goods and services are divided for registration purposes into classes, in respect of which a mark may be registered. Pharmaceuticals fall within Class 5, but the scope of many of the classes (of which there are 42) is very wide. Class 5, in fact, covers pharmaceuticals, veterinary and sanitary substances, infant and invalid foods, plasters, material for bandaging, material for filling teeth and dental wax, disinfectants and preparations for killing weeds and destro)dng vermin.
