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 ...

traditional building technologies have much to teach us about how to design regionally appropriate structures. the orosi is one of these useful technologies, which has been used for many centuries in order to control the harsh sunlight in iran. this architectural element was rather important because the intensive solar radiation could easily damage valuable carpets used in most spaces in persia...

The impetus behind this s‌tudy is to discover the aes‌thetic and semantic patterns of the cypress tree and show how this element has been employed by Iranian artis‌ts. The ques‌tion of this research is how a cons‌tant element (the cypress tree) has been transfigured in different Iranian arts. Four categories of miniature, carpet, textile and architecture decoration. The present research is qual...

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 ...
