Swedish Textile Recycling Company Wants To Create Higher Technology

There are not many companies that recycle old clothes.

However, how to use recycled fabrics to produce new high quality environmentally friendly fibers is still a major problem in the industry.

Recently, the Swedish textile recycling company re:newcell AB announced that the company's new cotton recycling mode will revolutionize the fashion industry, and truly achieve efficient use of resources.

At present, the company has begun to build demonstration plants.

According to Fibre2Fashion, re:newcell AB is using new technology to pform jeans, T-shirts and other old clothes into new textile size, which can be used to produce new clothes.

The factory is located in the AkzoNobel (AKZO NOBEL) plant of Kristinehamn, Sweden, and is expected to be in the first quarter of 2017.

The company said it was based on

The textile fiber recycling process can greatly extend the use time of human resources.

Re:newcell AB, a new technology developed in Stockholm's laboratory, can pform waste textiles into new pulp - dissolving wood pulp (currently obtained mainly from trees).

Dissolving pulp is mainly used to produce high quality environmental protection textile fibers such as Viscose (viscose fiber) or Lyocell (soluble fiber).

At present, the global demand for textiles is 90 million tons per year.

The natural materials such as viscose fiber account for only 1/3 of them, and the rest are mainly petroleum based materials, such as polyester, spandex and nylon.

By extending the life span of existing natural materials to expand the total resources, it is imperative for consumers and large fashion companies.

So far, the quality of recycled cotton can not meet the requirements of the fashion industry, but the re:newcell recycled slurry can be achieved.

Nordic pulp manufacturers have made breakthroughs in the research and development of wood pulp textile fibers, after which manufacturers developed an environmentally friendly production method that made white wood and pine trees into garments and sofa fabrics.

The company began to develop this technology in 2012, and now the whole process is basically mature. At present, it is investing 8 million euros to build a production line.

Malcolm Norlin, chairman of the board of directors of the company, said: "we are delighted to be able to move forward and contribute to the sustainable textile industry.

Kristinehamn's excellent geographical location enables us to get access to the excellent technology of large-scale production with high efficiency of resources utilization, and it is also a great advantage to operate in a first-class factory like AkzoNobel.

Now the new spindle has reached 25000 turns per minute.

If the old traditional spindle 7.8 exceeds 15000 turns, it will face a lot of practical problems, such as a lot of electric energy consumption, noise increasing, spindle life shortening, yarn quality dropping and so on.

Nowadays, new spinning equipment has put forward higher requirements for spindles.

Now let's take a look at the basic requirements of new spindles.

Spindle speed should reach 25000 rpm, or even more.

At high speed, the spindle requires low noise.

3. The speed of spindle belt should be within the normal range.

It is not necessary to increase spindle speed by increasing spindle tension.

(4) when the spindle runs at high speed, the vibration of the spindle is small.

At any normal spinning speed, the spindle energy consumption is low.

If we want to achieve the above five requirements, we must first reduce the diameter of the spindle, so that the speed of the spindle belt can be reduced.

To reduce the diameter of the spindle, we should first reduce the diameter of spindle bearing and the diameter of spindle.

However, after reducing the diameter, the spindle should also bear the changing force (normal speed and maximum speed) caused by the change of spindle speed without bending and breaking.

This depends on the selection of high quality steel and precision machining technology.

At the same time, the spindle bar needs to be shortened to get enough tough performance, and the bearing parts and the bottom of the spindle need to be redesigned due to the decrease of spindle diameter.

In order to meet the needs of high-speed operation, the spindle vibration absorption system is also strengthened.

In view of the above requirements: spindle manufacturers at home and abroad show great powers and have done a lot of work.
