Shandong DAIYIN Textile and Garment Group (D & Y Group) get approval for it two new textile technology projects, by an appraisal committee of nine well-known domestic textile experts led by the Chinese Academy of Engineering academician Yao Mu.
The first project denim dyeing technology was tested by Shandong Quality Inspection Checkout and Test Center of Textiles and the quality indicators have met the industry FZ/T 13001-2013 dyed yarn denim standard grade technical requirements. The combination of denim paints and dyes dyeing technology has filled the domestic blank in China and reached the international advanced level.
The project integrated the fusion of the paint staining technology with the existing indigo, sulphur dyeing, and proposed three technology routes in shaping machine, including grey denim pigment dyeing, traditional indigo with sulphide denim padding paint colour, and the base registered yarn coating in the slurry dyeing combination machine.
The production technology has a short flow that can adapt to a variety of denim washing processes. The project used pigment dyeing techniques that enriched the denim fabric staining method, overcame the shortcomings of traditional single colour dyeing method, reduced the discharge of sewage water during the dyeing and washing process, and achieved energy-saving, emission reduction, as well as clean production.
The second project anti bacterial textiles was tested by Shandong Quality Inspection Checkout and Test Center of Textiles and the quality indicators have reached the industry standard FZ/T 12028-2012 requirements. The antibacterial performance indicators have reached the national standard GB/T 20944.3-2008 technical requirements. The development of vehicle interior fabrics with the combination of filament and staple fibres composite spinning technology and spinning colouring process has filled the domestic blank of antibacterial textiles and the technology has reached the leading domestic level.
The project has adapted short fibre wrapped composite spinning production technology and has achieved the application of low proportion silver ion anti-bacterial fibre in automotive interior fabrics. The colour spinning technique it applied has avoided injury to the antibacterial fibre in the process of the fabric alkaline treatment thus ensuring the antibacterial effect of the finished product.
The filament staple composite yarn was introduced into woven fabrics and warps knitted fabrics and broadened the use of yarn and provided a new product of high-grade function for automotive interiors fabrics. The project technology is mature and stable and the production process is short with low cost.
D&Y Group ranks among the top 20 textile enterprises in China with 500,000 spindles, 10,000 air spinning, 2,000 looms, 3500 (sets) sewing equipment production scale, advanced equipment and strong technical force. It employees over 10,000 people annually produces 80,000 tons of cotton yarn, 20 million metres of denim, five million metres of wool and five million pieces of clothing.
