Melt Blown Polymers | Process Flow Chart of Melt Blown System | Application of Melt Blown Polymer Products
Melt Blown Polymers
Introduction:
Melt blowing is a process for producing fibrous webs or articles directly from polymers or resins using high-velocity air or another appropriate force to attenuate the filaments. The melt-blown process is one of the newer and least developed nonwoven processes. This process is unique because it is used almost exclusively to produce microfibers rather than

Concept of High Volume Instrument (HVI) | HVI Used in Bale Management System
High Volume Instrument (HVI):
The testing of fibres was always of importance to the spinner. It is done by the HVI machine. High volume instrument systems are based on the fibre bundle strength testing, ie, many fibres are checked at the same time and their average values determined. Traditional testing using micronaire, pressley, stelometre, and fibro graph are designed to determine average

Water Hardness | Problem Caused by Hard Water in Wet Processing/Dyeing Industry
Hardness of Water:
Hardness is traditionally measured by chemical titration. The hardness of a water sample is reported in milligrams per liter (same as parts per million, ppm) as calcium carbonate (mg/l CaCO3). Calcium carbonate hardness is a general term that indicates the total quantity of divalent salts present and does not specifically identify whether calcium, magnesium and/or some
Physical/Chemical Properties of Water in Textile Wet Processing | Standard/Ideal Quality of Dye House Water
Water in Textile Wet Processing:
In wet processing, water consumption is used greater than the amounts of fibers processed. It is the ubiquitous solvent for the solutions of chemicals used. For this we should know details about water. Physical and chemical properties of water are given below:
General Properties / Physical Properties of Water:
1. Water when pure has no color no taste and

Colorfastness to Chlorinated Water | Color Fastness to Chlorine
Theory:
The test method by which this test is carried out is ISO 105 E03. Chlorinated Pool water fastness is getting more importance in Terry Towel industry for swimwear and also for yarn dyeing. This method is designed to evaluate the resistance to Chlorinated Pool Water of any colored textile substrate. Here, the test specimen is treated in diluted Chlorine solution under specified conditions

What is Lab Dip | Objects of Lab Dips | Process Sequence of Lab Dip
Lab Dip:
A lab dip is a swatch of fabric test dyed to hit a color standard. It is a process by which buyer’s supplied swatch is matched with the varying dyes percentage in the laboratory with or without help of spectrophotometer. Lab dip plays an important role in shade matching & this is an important task before bulk production. In previous article of this author we have to learn on flow chart
