Dyeing Process of Cotton Fabric with Azoic Dyes

by

Introduction Azoic dyes, characterized by their insoluble azo group (-N=N-), are unique in that they are not available in a ready-made form. These dyes are produced through a chemical reaction between two components: a coupling compound (naphthol) and a diazo compound or diazo salt. The resulting colored substance is insoluble in water and exhibits excellent … Read more

A mass of 150g was hung in turn from 250 pieces of a certain yarn, and 12 of the pieces broke. A load of 200g was then hung from the previously unbroken pieces and a further 213 pieces broke. Assume that yarn strength is distributed normally. Estimate the mean and standard deviation of the yarn strength.

by

The proportion of yarn that can withstand 150g of load, = 238/250 = 0.952 The proportion of yarn that cannot withstand = 1-0.952= 0.048 or 12/250 = 0.048 The proportion of yarn that can withstand 200g of load, = 25/250 = 0.1 Let µ and σ be mean and standard deviation of yarn’s strength Therefore, … Read more

A manufacturing company produces knitted sports goods. It is found that 2% of the goods produced are defective. What is the probability that in a shipment of 100 such goods 4% or more will prove to be defective?

by

Answer: To solve this problem, we can use the binomial probability distribution formula. The binomial distribution is applicable when there are two possible outcomes (defective or non-defective) and each trial is independent with a constant probability of success (defective in this case). Let’s denote: – (p) as the probability of a single item being defective … Read more
