Interview With Li Guoyuan, Deputy Manager Of Production Technology Department Of Tong Kun Group

It is the key development content of China's chemical fiber industry during the "13th Five-Year" period to continuously promote the implementation of the "three products strategy", enhance the competitiveness and influence of the "Chinese fiber" as a public brand and a batch of "enterprise brands".

In this process, the "China fiber fashion trend release" campaign will continue to play an important role.

In order to make

Downstream enterprises such as weaving, fabrics, terminal clothing and home textiles can better understand the forefront of innovative fiber in China's chemical fiber industry. From now on, this newspaper will launch a report on the "China fiber fashion trend 2016/2017 shortlisted products".

In the "2016/2017 entry product of China's fiber fashion trend", the "velvet soft polyester fiber" of Tong Kun group was selected as the category of "comfortable fiber" in the chapter of "fiber security defense".

Recently, our reporter interviewed Li Guoyuan, deputy manager of the production technology department of Tong Kun group on the detailed performance characteristics, current sales status and application in the downstream market of the fiber.

Reporter: please describe in detail the properties and characteristics of the soft imitation polyester fabric.

Li Guoyuan: imitation wool soft polyester fiber is a polyester semi dull fine denier porous flat fiber modified by special technology and equipment. It adopts the most sophisticated spinning equipment of Japanese TMT company, spinneret pass.

The reverse construction of the cup body broke through the technical bottleneck of the variation of the index.

The special cooling technology of bottom heating is adopted to ensure that the temperature below the spinneret is relatively stable, thus improving the slow cooling condition of the tow, changing the orientation structure of the fiber molecules and reducing the molecular crystallization rate.

With relatively low conventional spinning speed and spinning temperature, the product has the characteristics of high breaking strength, uniform evenness and high thermal stress. The index has reached the industry standard.

At the same time, through adoption

The unique short-range spinning one-step winding equipment, using carbon fiber ceramic network and ultra-low network pressure, produces products with high volume density and high capacity. It has the same hardness, no stacking and uniform quality inside and outside the whole roll width.

The prepared preoriented silk cake has beautiful appearance, good internal quality and small fluctuation inside and outside, making the product easy to process, stable in tension, soft and firm in product style, delicate in touch, uniform in color absorption and bright in color. It is a new product with high quality and high added value.

Reporter: please introduce the technical indicators of soft and soft polyester fiber.

Li Guoyuan: its technical index is: 1, linear density (dtex/F):230/192; 2, line density deviation rate (%): 3, linear density variation coefficient CV (%): less than 0.80; 4, fracture strength (CN/dtex): greater than 2.10; 5, breaking strength variation coefficient CV (%): less than 6.50; 6, elongation at break (%):120.0 + 6; kg, elongation coefficient of variation CV value (%): less than 6; CV, value of dry weight,% (CV) (%): < 0.

Reporter: what are the applications of this fiber in the downstream area? What are the characteristics of the fabric?

Li Guoyuan: the soft and firm style of imitation wool soft polyester fiber is mainly used in the production of imitation fabric, and is well received by customers.

The fiber is also suitable for the production of high-grade garment fabrics, which are mainly used for the production of suits and trousers.

The fabric is soft, medium and rigid, and presents a certain brightness. It is comfortable to wear and has a smooth appearance. It is not easy to wrinkle, washable and resistant to pilling. It looks unique and has a high grade, but the cost is not very high.

Reporter: how to look at the future development of the fiber market?

Li Guoyuan: at present, the velvet soft polyester fiber of Tong Kun group has entered the stage of full commissioning.

When the product was first put on the market, it was approved by the downstream enterprises and approved by the customers.

With the continuous development of the textile and chemical fiber industry, people's demand for fabric style is getting higher and higher. The products with unique style, smooth handle and colorful colors will be more and more popular among thousands of households.

The products that are woven with velvet soft polyester fibers are soft, smooth, bright, bright, and soft after finishing. The unique style will be concerned by more enterprises and consumers.

From the perspective of technology, large-scale polyester melt direct spinning production can achieve lower cost, energy saving and emission reduction for enterprises, and achieve better economic benefits and broad prospects for development.

On the whole, as people's requirements for living environment and quality of life are getting higher and higher, conventional fibers can no longer meet the market demand. Differential and functional textiles will develop rapidly, and will also be an important development trend of textiles in the future.

Compared with traditional fabrics, functional fabrics are highly targeted, and one or more performance indicators are higher than ordinary fabrics.

The production of imitation wool fabrics can be realized by using velvet like polyester fiber. Its soft and warm characteristics can replace natural wool products. This also reduces the demand for natural wool to a certain extent. Therefore, it is expected that the market space of the fiber will expand day by day.

Reporter: what are the most prominent advantages and characteristics of imitation wool soft polyester fiber?

Li Guoyuan: the conventional polyester fibers are basically made of circular cross section spinneret. The most prominent advantages and characteristics of the imitation wool soft polyester fiber are that they are made of spinneret with flat cross-section, which not only has the characteristics of warmth, softness, and smooth handle, but also the fluff of the woolen fabric is not easy to fall down, but it is soft and medium.

For example, after touching with other articles, the fleece can be restored to the original erection state in a short time, and is very suitable for making plush toys, car upholstery cushions, and imitation coat.

Reporter: which year did the fiber enter the market? What is the current sales situation? What is the profit contribution to the company?

Li Guoyuan: the fiber began to market in 2014. The average selling price (including tax) was 800 yuan / ton ~1000 yuan / ton.

In 2015, shipments increased by 18.44% over the same period last year. The average selling price (including tax) was 400 yuan / ton ~500 yuan / ton, and the gross profit margin was about 12%.

Overall, the high added value of the product has brought considerable economic benefits to the company. Under the market condition of regular polyester fiber, the product can bring continuous profits to the company.
