Carpet Preconditioning: Its Impact on Cleaning
نویسنده
چکیده
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 light reflected from cleaned carpet using the Association of Textile Chemists and Colorists (AATCC) gray scale to develop comparative ΔE values, did the carpet manufacturing and cleaning industries understand the importance of preconditioning.

X-ray Fluorescence Spectroscopy Method Development for Quantitative Evaluation of Carpet Cleaning Technology
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...
متن کاملModeling of exposure to carpet-cleaning chemicals preceding irritant-induced asthma in one patient.
42-year-old woman experienced an acute asthma attack, seizures, and unconsciousness immediately after a carpet-cleaning and deodorizing job was conducted in her home. Exposure modeling estimates that she was exposed to approximately 3.4-17 mg/m(3) of sodium tripolyphosphate and more than 14 mg/m(3) volatile organic compounds immediately after the cleaning. I derived two separate exposure models...

متن کاملThe vertical distribution of house dust mite allergen in carpet and the effect of dry vacuum cleaning.
BACKGROUND Carpets are large reservoirs of the dust mite allergen Der p 1. The effect of vacuum cleaning on the distribution of Der p 1 in carpets is poorly understood. METHODS Samples were cut from 7 used household carpets, all over 5 years of age. From each carpet, 10 samples were left untreated, 10 vacuumed with an upright vacuum cleaner, and 10 vacuumed with a canister vacuum cleaner. Eac...
متن کاملUse Of Hoekens And Pantograph Mechanisms For Carpet Scrapping Operations
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 ...
