Exclusive Interview With Murata, Japan -- The Leader Of Eddy Spinning Equipment
mVS
It was developed on the basis of jet spinning. It belongs to the category of free end spinning. It was first designed and invented by German Gatzfreid in 1957. It was not popularized because of its low strength and poor yarn strength.
In the mid 70s of last century, Poland and Japan began to study the improvement of vortex spinning.
In 1986, Poland produced PF-2 and PF- 2RA eddy current spinning machines for producing core spun yarn, but it did not develop due to changes in Poland's political situation and economic downturn.
Murata, Japan, has become the only enterprise that is committed to the continuous improvement of eddy spinning. From the original MVS850 type to the current NO.861 type, Murata vortex spinning machine technology has been continuously improved.
Over the past 20 years, Murata has sold over 1000 eddy spinning machines around the world.
In 2008, the Swiss Lida Company also studied a kind of swirl spinning machine, and the spinning principle was basically close to the swirl spinning equipment of Murata company, but it has not been popularized so far.
At present, vortex spinning equipment has attracted more and more attention in China, and the controversy about eddy current spinning equipment has been continuously.
Recently, the China Textile Economic Information Network interviewed the Murata manager of Murata machinery (Shanghai) Co., Ltd., which is responsible for the sale of vortex spinning equipment on the development of eddy spinning equipment.
I hope it will give some inspiration to the textile enterprises that want to introduce eddy spinning equipment.
CTEI: Murata vortex spinning machine is suitable for those.
raw material
What is the number of spinning parts?
Murata: the vortex spinning machine is mainly suitable for spinning cellulose fibers and chemical fiber blended yarns.
At present, market development mainly focuses on the following products.
1. The spinning number of Rayon 100% is Ne20 to Ne60.
Modal100% spinning number Ne20 to Ne60
T/R (65/35, 50/50) spinning number Ne20 ~ Ne40
(4) the spinning number of blended cotton (Viscose / cotton) is Ne20 to Ne50.
5. T/C (80/20 to 40/60) spinning number Ne20 ~ Ne50
Vortex spinning equipment can also spin pure cotton yarn and other varieties. But because of the difficulty in spinning pure cotton yarn, according to our current sales policy, it is not recommended for customers to spin pure cotton varieties.
CTEI: what are the characteristics of the vortex spinning equipment?
Murata: "by high speed."
Do spinning
With the integration of processes, we create a high value-added yarn with strong functionality and leading fashion. This is the concept of Murata vortex spinning machine.
Our new VORTEX No.861 is the fastest spinning equipment in the world. It can reach 450 meters per minute and yield more than 20 times that of ring spinning.
Through the integration of roving, spinning and winding process, the vortex spinning machine can control the cost of production, such as personnel configuration, power consumption, maintenance and maintenance, and so on.
At the same time, the combination of MSC (Muratec electronic clearer) and VOS (visual intelligent control computer system) not only achieves quality management, but also achieves simple and precise centralized management.
By installing MSC - F (selecting parts), the detection of foreign fibers can also be completed.
Under the same conditions, the vortex spinning machine saves more floor area and labor than other spinning equipment.
Compared with 10 vortex spinning, 20000 spindles ring spinning is 40 hours of viscose 100%. The output of vortex spinning is 265kg/ hours, occupying 1686 square meters, 11 for workers, and 3486 square meters for ring spinning, 25 for workers.
In addition, the vortex spinning machine is more energy efficient.
Under these conditions, the power consumption of vortex spinning is 30% lower than that of ring spinning.
The vortex spinning machine is also more economical in parts maintenance.
CTEI: which devices can be equipped with the vortex spinning machine?
The matching device, such as (1) electric cleaning, has the function of detecting and removing foreign fibers (mainly for natural fibers); (2) waxing device (for high-grade knitting yarns), which can be used for stable and uniform waxing, and can be used for 45 mm wax blocks. When the wax is not waxed, the motor can be stopped, and energy loss is reduced. A wax block residual alarm device is also set on the single spindle. (3) the yarn conveyor belt (reducing the labor intensity of the truck); (4) the core spun yarn processing device has 3 types, the composite core spun yarn device, the elastic fiber core spun yarn device, the hybrid type (composite core spun yarn and the elastic fiber core spun yarn dual-purpose device). Murata: we have some options on the equipment.
CTEI: how are the sales of eddy spinning equipment in the Chinese market?
Murata: eddy spinning equipment has been selectively sold. After the liberalization of the Chinese market in 2009, sales were hot.
Enterprises that purchase vortex spinning equipment must have a certain level of technology and management. Products must have downstream customers' needs and sales channels should be unblocked. The main products of enterprises should have cellulose fiber series, because vortex spinning equipment is not very suitable for spinning pure cotton varieties, so we usually do not sell to cotton varieties in sales, which is also responsible for the interests of enterprises.

What progress has been made in the research and development of CTEI: vortex spinning products?
Murata: in the research and development of vortex spinning, we will strengthen the research and development of the following categories of products. One is the polyester, viscose and polyester cotton woven fabrics. Due to the characteristics of less hairiness, the fabric is clear in appearance and the fabric is also outstanding in washing resistance. Therefore, these varieties can play a strong role in their work clothes and home textile sheets. Two, pure polyester products, strong water absorption and anti ball ability make them have incomparable advantages in knitted sportswear. Three, pure cotton products, highlighting the characteristics of water absorption and hard handle.
CTEI: what are the technical services provided by Murata after the company purchased Murata vortex spinning equipment?
Murata: after the customer purchases the vortex spinning equipment, the division will provide perfect after-sales service and technical training, and customers can join the PARTNER's global vortex spinning promotion system (website). We have introduced a lot about vortex spinning on this website. We will also login the customer information to the system after the customer's permission, so that we can find the vortex spinning line manufacturer for the customers who need the vortex yarn.
At the same time, we also participated in some large-scale textile exhibitions to promote vortex spinning terminal products, such as EXPOFIL, INTERTEXTILE and so on.
CTEI: what is the market situation of Japan's vortex spinning products?
Murata: as a differentiated vortex spinning product, it is very popular in the Japanese market, especially in terms of cellulose fiber and TR blended products.
Moreover, the price of vortex spinning products is generally higher than that of ring spinning products.
CTEI: what are the technical difficulties in the development of vortex spinning core spun yarn?
Murata: the strength of vortex spinning spandex core spun yarn is lower than that of ring spinning. Because the spandex is elastic, it is more difficult in the production process. This variety is also a variety that we have been developing and perfecting all along.
Vortex spinning filament (non elastic) core spun yarn technology is relatively mature, and can solve the problem of relative strength of vortex spinning line is insufficient, it is a potential product of vortex spinning products.
CTEI: what is the development status of the international vortex spinning equipment?
Murata: Murata is the only manufacturer selling eddy spinning equipment in the world.
Murata has been developing eddy spinning equipment since the 90s of last century. The 861 type vortex spinning machine is the third generation of the company. We will continue to invest in the development of eddy current spinning in the future, and continue to lead the international vortex spinning market.
