最近正在做纤维的功能化的事情！了解到一些该方面的文献如： Patent Number(s): CN1821463-A Title: Bamboo carbon polyester fiber/chitin viscose fiber blended yarn and producing method Inventor(s): WANG Q, WANG H Patent Assignee Name(s) and Code(s): UNIV DONGHUA (UYDO-N) Derwent Primary Accession Number: 2007-124882 [13] Patents Cited by Inventor: 0 Patents Cited by Examiner: 0 Citing Patents: 0 Articles Cited by Inventor: 0 Articles Cited by Examiner: 0 Abstract: NOVELTY - The present invention is blended yarn of bamboo carbon polyester fiber and chitin viscose fiber in the ratio of 45-55 %. The production process of the blended yarn includes the following steps: mixing and spinning bamboo carbon polyester fiber of linear density 1-3 D and chitin viscose fiber of chitin content not lower than 5 % and linear density 2-3 D to form the blended yarn of bamboo carbon polyester fiber and chitin viscose fiber. The blended yarn of bamboo carbon polyester fiber and chitin viscose fiber is superior to available yarn of bamboo carbon polyester fiber, and has the has functions of adsorbing and eliminating bad smell, emitting far infrared ray, releasing negative ion, resisting bacteria, high hydroscopicity, soft hand feeling and comfort, and is suitable for making underwear.

Houa,b, G.S. Zhoua, M. Zhenga,* a School of Materials Science and Engineering, Xi’an Jiaotong University, Xi’an 710049, People’s Republic of China b School of Mechanical & Material Engineering, China Three Gorges University, Yichang 443002, People’s Republic of China Received 2 April 2003; accepted 19 June 2003 Abstract The shell of pink conch is a kind of natural well-designed composite with excellent mechanical properties, which provides us information for material design. In this paper the microstructures of pink conch shell are characterized by using SEM and TEM. The microscopic analysis indicates that the pink conch shell is with crossed-lamellar microstructure and the angle between two second-order lamellae is 70–90. The cracking and fracture morphologies indicate that the crack deflection, bridge and fiber pullout are the main toughening mechanisms. Bamboo lamellae are employed to make the simple bio-mimetic model materials. In the model material the rotated angle between the fibers of each glued lamella varies from 0 to 90. Three-point-bending is employed to test the properties of models material, such as the elastic modulus, the flexural strength and the fracture strain energy density. It is found that the fracture strain energy density of the specimens with the rotated angle between the fibers of the layers about 60 exhibits the maximum value, which is close to the angle of the two second-order lamellae of the conch shell. r 2003 Elsevier Ltd.

Effects of vascular fiber content on abrasive wear of bamboo Jin Tong ∗, Yunhai Ma, Donghui Chen, Jiyu Sun, Luquan Ren The Key Laboratory of Terrain-Machine Bionics Engineering (Ministry of Education, China) and College of Biological and Agricultural Engineering, Jilin University (Naling Campus), 5988 Renmin Street, Changchun 130025, PR China Received 25 August 2004; received in revised form 16 March 2005; accepted 23 March 2005 Abstract Natural biomaterials have unique structures and some distinguishing properties for adapting themselves to natural surroundings. Bamboo is a natural composite reinforced with longitudinal fibers (vascular fibers). The abrasive wear property of the cross section of bamboo (Phyllostachys pubescens) stem was examined. The abrasive material used for tests was the mixture of quartz sand (96.5 wt.%) and powdered bentonite (3.5 wt.%) and contained a water content of 3 wt.%, simulating soil condition The size of the quartz sand particles was 0.104–0.214 mm, 0.214–0.420mm and 0.420–0.840 mm, respectively. The abrasive wear tests were run on a rotary disk type of abrasive wear testing machine. The relative sliding velocity was 1.68, 2.35 and 3.02 m/s, respectively. It was concluded that the abrasive wear resistance of the cross section of the bamboo stem was a function of the vascular fiber content of bamboo, the abrasive particle size and the relative sliding velocity. The wear resistance of bamboo was increased with its vascular fiber content. A higher sliding velocity or a larger abrasive particle size resulted in a higher abraded volume of bamboo. The effects of the tensile strength and the impact strength of bamboo on its abrasive wear were discussed. It was found by scanning electron microscopy that the geometric morphology of the abraded surfaces of the sections of bamboo stem displays a not-smooth structure. This not-smooth surface morphology provides a clue to develop anti-abrasion morphological surfaces of soil-engaging components. |
