How to crinkle a Fabric

In the basic process, the fabric is soaked in water. It is then twisted into the form of tight rope. It is then again twisted in on itself until becoming basically a ball of twisted fabric. The ends are tucked in so the fabric doesn't come untwisted. Then it is dried using microwave or other means. It is not recommended that the damp twisted fabric ball be left overnight otherwise it will mildew.

What is the difference among Mulberry, Tussar ( Tasar), Muga and ERI Silk

The difference is in the type of worms producing the yarn and the types of leaves they eat.

Mulberry Silk is obtained from BOMBYX MORI feeding on MULBERRY leaves.


Tussar Silk is obtained from ANTHEREA MYLITTA feeding on ARJUN and ASAN leaves.


Muga Silk is obtained from ANTHEREA ASSAMENSIS feeding on SOM and SUALU leaves.

Eri Silk is obtained from CYNTHIA RICINI  feeding on CASTOR OIL leaves.

The eri silk worm is the only completely domesticated silkworm other than Bombyx mori.

Spinning Mills Vs. Garment Sector: Who will bear the Burden

This Article is related to Textile Industry in India

With the rising cotton yarn prices, the garment manufacturers are feeling the heat. Unable to pass on the price hike to the customers, they are turning back to the government for relief. The government has done its part by the following measures:

1. Government has withdrawn 7.67 percent DEPB Benefits for cotton yarn exports.

2. It has also introduced a cess on export of cotton yarn.

This step is take with the following assumptions:

a. Cotton yarn prices have increased because of rising export demands.

b. It is hampering the domestic garment producers and exporters.

c. While domestic markets are able to absorb the increased cost, recession hit West is unable to.

d. It is difficult to pass on the price increase to the customers.


But Will it lead to desirable results

Arguments against

a.  Social Argument: Spinning mills in the country have suffered huge losses during the last two years. They need to make some profits this year.

b. The problem could be solved by giving more assistance to the garment exports to absorb thee additional costs.

c. Less than 20% of cotton yarn produced get exported. Total exports of cotton yarn this year are less than that of last year.

d. The cut in DEPB will not affect much as long as the  global markets are able to absorb the additional costs.

e. The problem can also be solved by improving production efficiencies in Garment manufacturing units so that they can absorb the high yarn prices without passing them on to the customer.

f. It is not only raw-material prices that have gone up. Labor cost and power cost have also increased.

Arguments in Favour

a. In Tirupur, there is an 11% drop in shipments over last year of knitted fabrics.

b. Spinning mills have jacked up cotton yarn prices disproportionately vis-a-vis input costs. Thus eg. raw material prices have risen by 1.79%, but yarn prices have gone up by more than 10%.

Principle of Soft Flow Dyeing Machine

Textile material can be dyed using batch, continuous or semi continuous process.

Batch processes are the most common method used to dye textile materials. There are three general types of batch dyeing machines:

1. In which fabric is circulated
2. In which dye bath is circulated
3.  In which both the bath and material is circulated.

Jet dyeing is the best example of a machine that circulated both the fabric and the dyebath. Jet dyeing is used for knitted fabrics. For Terry-towels soft flow dyeing is use.

In jet dyeing machine the fabric is transported by a high speed jet of dye liquid.

As seen in the figure, this pressure is created by venturi. A powerful pump circulates the dyed bath through a heat exchanger and the cloth chamber. Cloth guide tube helps in circulation of fabric.

The vigorous agitation of fabric and dye formulation in the cloth increases the dyeing rate and uniformity. It minimizes creasing as the fabric is not held in any one configuration for very long.  The lower liquor ration allows shorter dye cycles and saves chemicals and energy.

In soft flow dyeing machines the fabric is transported by a stream of dye liquor. However, the transport is 

assisted by a driven lifter reel.

These machines use a jet having lower velocity that that used on conventional jet dyeing machines.

The soft flow machines are more gentle on the fabric than conventional jet machines.

The following are the features of a soft flow U-Type dyeing machine offered by Taxfab:

1. Machine pressure vessel and major wet parts made of stainless steel AISI 316/ 316 L, highly corrosion resistance material.

2. Heavy duty stainless steel centrifugal pump for optional dye liquor circulation. Highly efficient heat exchanger for fast heating and cooling. 

3.  A stainless steel filtering device placed in such a way for easy cleaning. 

4.   A unique design of jet nozzle can provide high discharge of liquore with subsequent pressure to ensure fast movement of fabric transport upto 300 Mtrs / Min., and the speed of fabric can be adjusted, required to desire quality. 

5. A mirror polished fabric transport perforated basket for easy trouble free movement of fabric from back to the front of machine, perforated basket fabricated in such a way that welding part does not come in contact with fabric.

6. For preparing chemical, colour kitchen tank is provided made out of stainless steel 316, with required valves for auto dozing. 

7. All valves is made of investment casting and is of stainless steel 3l6.

8.Electrical control panel with microprocessor to operate the machine is provided with pneumatic control circuits.

9. Magnetic level indicator duly calibrated for correct liquor measurement. 

10.       Take off reel with direct couple geared motor and stainless steel structure 

11. All safety device required for a pressure vessel is incorporated with the machine.

A front view and side of the machine offered by them is as given below:
