Tuen Mun 1: Look at raw materials
The raw materials of high-quality pure wool carpets are generally made of fine wool. The hair is long and uniform, soft and elastic, and has no hard roots. The raw materials of inferior carpets are often mixed with moldy and inferior hair and acrylic fiber. Short and uneven thickness, no elasticity when the hand is groping, there are hard roots.
Tuen Mun II: Look at the appearance
The high-quality pure wool carpet pattern is clear and beautiful, the suede is lustrous, the color is even, the pattern is clear, the underside is soft and smooth, and the inferior carpet is light in color, the pattern is fuzzy, the plush is sparse, and the ball is easy to get rid of the ball. dirty.
Tuen Mun 3: Look at the foot

Tuen Mun 4: Look at the craft
The high-quality pure wool carpet has exquisite craftsmanship, the carpet surface is straight and the lines are regular; the inferior carpet has rough workmanship, more leaky lines and exposed bottoms, and its weight is also significantly lower than the quality products due to the small density.
High performance Engineering Fiber is high-level technology and new products and widely applied in construction and water conservancy projects like tunnels, concrete roads, asphalt highway to improve the anti-shock, anti-creak, anti-leakage and anti-impact performance and strengthen the concrete tenacity. Products include three series as below:
1. S.B Building Fiber--widely applied in the construction projects with cement concrete or cements mortar to enhance effectively its firmness and durability.
2. DCPET Fiber for Asphalt Road Surface--applied in high-level asphalt pavement construction to improve its quality and extend the service time.
3. High Performance polypropylene fiber (HPP Fiber)--applies in asphalt road, airport runway, tunnel, water conservancy projects and coastal area pier projects to improve construction-controlling interstice of concrete, strengthening ductility. It can replace traditional steel fiber and reinforcing steel network.
