Since the Institute of Inspection, Cleaning and Restoration Certification (IICRC) wrote the first carpet cleaning standard in 1991, preconditioning carpet to maximize soil suspension prior to soil removal has been an industry-accepted practice. However, not until The Carpet and Rug Institute (CRI) implemented its Seal of Approval (SOA) program, which included spectrophotometer measurement of li...
Post-consumer carpet represents a high volume, high energy content waste stream. As a fuel for co-firing in cement kilns, waste carpet, like waste tires, has potential advantages. Technological challenges to be addressed include assessing potential emissions, in particular NO emissions (from nylon fiber carpets), and optimizing the carpet feed system. This paper addresses the former. Results of...
An X-ray fluorescence method for measuring the quantity of test matter removed from carpet by vacuuming and wet extraction in typical carpet cleaning processes is described. In this cleaning effectiveness analytical method, five different test compounds were incorporated into an artificial soil, which was then applied to a test carpet. X-ray fluorescence was used to quantify these elements afte...
In this paper we present a model for the carpet cutting problem in which carpet shapes are cut from a rectangular carpet roll with a fixed width and sufficiently long length. Our exact solution approaches decompose the problem into smaller parts and minimise the needed carpet roll length for each part separately. The customers requirements are to produce a cutting solution of the carpet within ...
CONTEXT Chronic exposure to talc in the course of carpet installation can result in pneumoconiosis. CASE PRESENTATION We present a case of a young carpet installer who was diagnosed with silicatosis of the lung. Review of occupational history revealed that the patient had been working as a carpet installer for approximately 15 years, since he was 15 years of age. The patient was exposed to ta...

Epidemiological and microbiological studies were conducted in a hospital room with carpet (CR) and in one with carpet (NCR). Microbiological profiles were determined with specimens obtained from patients admitted to these rooms. Patient records were reviewed to note infection status and other case identities. Eleven-millimeter cylindrical core samples of carpet were obtained, and swab template ...
For washing of carpets, scrapping is done using a wooden plank. The edge of the plank gives pressure on the carpet to remove dirt particles and water from the carpet surface. The plank follows a straight-line path on the carpet surface. In this paper Hoekens and Pantograph mechanisms are used to obtain a straight-line path for carpet scrapping. Hoekens four-bar mechanism can produce the same ...
Cognitive deficits experienced by older adults with dementia limit use of wearable devices (necklaces or bracelets) that summon assistance after the older adult falls. To use these wearable devices, older adults must choose to wear them, remember how to use them, and be conscious after falling. Devices such as the Smart Carpet substitute pre-programmed or automatic functions for functions requi...
purpose : to determine the effect of carpet weaving on refractive errors methods : in this cross sectional study, carpet weavers and non-weavers in the normal population of mashhad were regarded as exposed and non-exposed groups, respectively. a carpet weaver was a person who wove carpets 7 hours a day for at least 2 years. the non-weavers group was selected from the population of mashhad throu...
