Technological Innovation In China'S Cotton Textile Industry Promotes Profit Growth

In 2013, the cotton spinning industry seems destined to be a "change" year. The implementation of the new cotton standard has been changed to "color grade" for many years, making cotton inspection more scientific and practical, and the cotton subsidy policy which is increasingly popular. According to industry sources, it has also come to an eyebrows recently, and the concrete plan is expected to come out in the near future.

Now that 2013 is approaching the end of the year, what has been achieved in the industry in the past year? Recently, the China Federation of textile industry has released the list of "China Textile Industry Federation's science and technology awards". It can be said that this is a transcript of the textile industry, which records the sweat of 2013 and adds a little confidence to the arrival of the 2014.

It meets the market demand for the diversification of spinning styles, and has great application space in infant clothing, bed products, underwear and other markets.

　　 Project Name: vortex Hibiscus Spun yarn Technology research and product development

Dezhou Huayuan Ecological Technology Co., Ltd.

Award: 2013 China Textile Industry Federation science and Technology Award three prize.

Characteristics of the project: the yarn developed by this technology can achieve coloring effect without dyeing, and has some advantages of the colored spinning yarn, which is in line with the demand of the textile industry for low carbon, environmental protection and energy saving products.

The introduction of the project: the parallel core fiber of air-jet vortex spinning yarn is affected by the raw material spinning equipment, and the number of wrapping fibers is easily reduced, resulting in the serious quality problems such as weak twist yarn. The development of the project was based on the vortex spinning core spun yarn, and the traditional characteristics of the core spun yarn were strictly covered. After a series of development steps such as the establishment of the style, the optimization of raw materials, the target test and the process optimization, a new vortex spinning core spun yarn with a unique and natural color in the yarn was developed.

The project uses a high proportion of colored core yarn to make the filament exposed naturally and evenly in the yarn in vitro. After using the vortex lotus spinning line, special dyeing effect can be achieved without dyeing machine. The combination of brocade spinning technology and vortex spinning core spun yarn technology makes the production of vortex spinning Hibiscus yarn more stable and quality more perfect. At the same time, softening protein yarn was used in the outsourcing fibers, and the soft yarn technology was adopted to improve the feel of the vortex spinning line and improve the added value of the product. The product produced by the project has a natural three-dimensional effect, improves the added value and production efficiency of the product, and meets the demand for personalized, differentiated and fashionable textiles.

　　 Project Name: Denim fabric High elastic finishing technology and its industrialization

Completion: Shandong Dai Yin Textile Group Limited by Share Ltd.

Award: 2013 China Textile Industry Federation science and Technology Award three prize.

Characteristics of the project: the high elastic denim fabric made by this technology is comfortable and smooth, and eliminates the common weft phenomenon in the pre shrinking process and improves the inner quality of the fabric.

Project Description: Based on the traditional production line of spandex elastic fabric, the technology project is based on the improvement and innovation to study the mechanism of the dry and wet changes, the tension state and the tension free state of the spandex filament during the pre shrinking finishing process, and the influence on the elastic properties of the spandex filament. The existing CLMA445G-180 pre shrinking finishing machine was designed and reconstructed, and the finishing process of elastic denim fabric was innovated. Through the grafting of pine drying technology and wet cloth technology in the pre shrinking machine, the PLC frequency conversion synchronous control is adopted, so that the conventional pre shrinking machine has a brand-new function, and the high elastic property of elastic fabric is given under the retaining of its conventional pre shrinking function, which effectively solves the problem of high shrinkage, small elasticity and poor dimensional stability existing in high elastic fabric.

This project integrates loose drying technology and wet cloth technology into cowboy fabric pre shrinking finishing equipment, and innovates the equipment and innovation of the process. Through the design of the drainage pipe for the wet dip cloth box, the drainage pipe can be adjusted and assembled, and it can be connected or disconnected from the washing tank according to the arrangement form, thereby effectively saving the waste of the auxiliary agent and reducing the color fading pollution of the fabric. The addition of a set of anti wrinkle and anti curling device can ensure the external quality and operational feasibility of the fabric, so that no wrinkles and curling can be made in the production of high elastic fabric.
