Lots of elastane in the products, and do you know why and how it effects the products?

Posted on by

Elastane was developed as an alternative to rubber in the 1950’s and is a thermoplastic polyurethane synthetic fiber. The unique property of this elastomer, as a result of its randomly coiled polymer structure made up of a mix of stiff and flexible segments, is that it can be stretched 500% or more without breaking or permanently deforming. Giving it the well-known characteristic of the ability to revert to its original shape after being stretched. The long amorphous segments in elastane create the elastic properties and the short rigid segments provide the structure when the fiber is stretched and released. Elastane has the highest stretch tension of all textile raw materials.

 

Elastane is soft, lightweight and abrasion resistant. Elastane is used where a high degree of permanent elasticity is required, as in tights, sportswear, swimwear and in woven and knitted fabrics. Adding elastane just for couple of percent makes fabrics more comfortable to wear. Elastane is always used in a blend with other fibers.

 

Elongation on an elastane yarn is much higher than on a more rigid yarn, like polyamide on Lymed fabric. When stretching a knit, the elastane yarn would practically never get to its limits of the elongation. This means, in most cases, that the elastane would not determine the ultimate elongation in the knit- determination is made by the rigid yarns in the fabric. Also, the construction of the knit has effect on the stretchability- looser the knit, stretchier the fabric.

 

More elastane content in a fabric does not mean that the fabric will have more stretch. By increasing the elastane content in the fabric, more resistance to stretch is created using the elastomeric material. More elastane means more powerful fabric.

Main Features and Benefits of CNC Milling Machine

Posted on by

CNC (Computer Numerical Control) milling machine is one of the common machine tools in machinery industry. It is the popular form of CNC that can perform those repetitive tasks of drilling and turning that used to be human jobs long time ago.

 

CNC Mills are classified based on the number of axes that they have. Axes are labeled as x and y for horizontal movement, and z for vertical movement.

 

Basically, this milling machine has four axes which are Milling Head Z, Table Z, Table Y, and Table X. The quantity of axes it has is often presented in many different ways.

 

For example, there is a five-axis machine. The extra 5th axis is in the form of a horizontal pivot for the milling head that ensure the excellent flexibility of machining with the end mill at an angle follow the table.

 

It is usually programmed by using a series of standard commands that we named it as G-codes to represent specific CNC tasks in alpha-numeric form.

 

There are many different sizes for this machine based on the purpose and location of usage, as well as the materials that need to be cut.

 

Besides that, the size of motor affects the speed of cutting the materials. Normally, materials like plastic and wood are the easiest things to cut, unlike steel that need stronger milling machine and longer time.

 

To evaluate the performance of milling, we can look at its rigidity. For example, the more rigid a mill is, the more precisely it drills and cuts. CNC mills normally have better & tougher engines for higher rigidity compared to manual counterparts.

 

With CNC milling machine, we can improve the speed of cut compared to manual operation. It also reduced the rejection when rigidity results increased. Thus, in long run business, it will indeed save a lot of time and overhead due to less wastage happened.

 

Another benefit is the accuracy of cut through CNC milling machine with a computer numerically controlled machine. In production line, it is very important to have all the parts produced exactly the same. However, nothing is perfect. CNC milling machine may also have a possibility of fault lies in the operator due to a mill can cut with absolute precision as close as.0001 of an inch.

 

In addition, many mills have beds that are able to move at different angles for easy cutting jobs, different angled cut as well as more difficult drilling operation. This is one of the benefits over manual mills.

 

Lastly, with the automated cooling systems, it is able to maintain the quality of raw material by spraying or blasting the hot metal or even tooling with specially formulated coolant.

 

With the benefits of CNC milling machine stated above, it is really worth the money to invest a CNC milling machine for your business use. And there are the popular brands that available in the market, such as Mori Seiki, Dahlih, CNC Takang, DMTG, Mastika, HACO, Takisawa, Okamoto, Creator, Agma, L & L, Hurco, Okuma, Extron, Enshu, Equiptop, Komatsu, Jiuh Yeh.
