Prediction and control of Surface Texture of Single Direction Crepe Chao Chen1,a ,Yongkai Liu1,b 1College of Textile and Clothing Engineering, Soochow University, Suzhou, 215021, China achenchao@suda.edu.cn,bliuyongkai21@163.com Keywords: single direction crepe; surface texture.
Surface texture of single direction crepe has close relationship with its shrinkage performance, which was influenced by thermal condition in the manufacturing process, and this shrinkage performance has something to do with the yarn material.
The ultimate reason for single direction wrinkles is that weft yarn was single twist filament and through twisting it had got certain torsional stress, which was a key factor to wrinkle depth and width of the fabric surface [3].
Warp firmness, weft firmness and twist multiplier are key factors affecting surface texture of single direction crepe.

Implementing Collaborative Innovation Accelerating Multi-cooperation for Vocational Colleges Feng Xiaoa, Yu Situb, Deng Wan Lic Sichuan Engineering Technical College, Sichuan Deyang, China axiaofength@163.com, bsty@scetc.net, cldw@scetc.net Keywords: Collaborative innovation, Vocational colleges, Multi-cooperation Abstract.
The key issue is how to cultivate practical talents for the requirements of the local economic and industrial development for vocational colleges.
Hu demands that universities and colleges should implement multi-cooperation with research institutes and industries and establish the collaborative innovation strategic alliance in key areas to achieve substantial results by sharing resources.
Vocational colleges in the process of implementation of multi-cooperation should guide enterprises to gradually understand and accept and focus on profit and potential non-material profits on the one hand.

Study on the secondary city, spatial expansion model of unifying adjacent cities Zhouchao1,2,a 1 Huaiyin Institute of Technology, School of Civil Engineering, Huai’an Jiangsu, 223001, China; 2 Department of Urban and Resource,Northwest University,Xi’an 710069, China; azhouchaokk@163.com KEY WORDS: Unifying adjacent cities; The secondary city; Spatial expansion; Model ABSTRACT: Urban spatial structure that is a comprehensive reflection of the interaction between human activities and natural factors, is the internal driving force mechanism for sustainable urban development.
factors promote urbanization in the suburbs, setting off another tide of urban expansion, it provides the impetus for the secondary cities to across the "threshold rule"; Construction of transport corridor--Traction power:Construction of transportation corridor and the industry belt are often the stretch axis of the main city and the secondary cities' spatial extension, and it has a point to the role to urban space expansion; speed of transport increased has injected new vitality for urban development, and it has provided favorable conditions to accelerate the pace of urban expansion; Needs of people living--Invisible Power:With the rapid economic development, urban living conditions gradually improved, "magnetic" elements[13] brought relocation of residents, has brought a corresponding relocation of the relevant departments within the city, and drives the outward expansion of urban space; Polarization and the diffusion effect--Basic power: Unifying adjacent cities speeds up population, material
In the secondary city district construction update, there grow up some new regional economic growth point in the intersection of transportation routes or external key towns, and form group urban plane with the main and secondary city district; farm-based permanent green space between new area and the secondary city district, become a buffer zone to protect the urban environment, avoid the inter-city space between sutured t, is a typical low-carbon, eco-city spatial structure model.

Because the Granier probe is sensitive to the change of temperature, the probes were external packaged radiation material to reduce the thermal radiation to probe the interference, at the same time it can prevent rain immersion effect to guarantee the determination results from the influence of a certain extent.

EDC-Crosslinked Electrospun Silk-Fibroin Fiber Mats Rong Liu1, a, Feng Zhang1, b, Baoqi Zuo1, 2, c, Huanxiang Zhang3, d 1College of Textile and Clothing Engineering, Soochow University, Suzhou, 215006, China 2National Engineering Laboratory for Modern Silk, Soochow University, 215123, China 3Department of Cell Biology, Medical College of Soochow University, Jiangsu Key Laboratory of Stem Cell Research, Suzhou 215123, P.R.
Recently, Silk fibrion nanofibers are used in various fields such as in biomedical, electrical and textile applications that includes tissue-engineered scaffolds, wound dressings and drug delivery systems because of their remarkable properties i.e., high specific surface area, increased strength and surface energy and enhanced thermal and electrical conductivity [2, 3].
The tensile strength measurements were then implemented using the instron material testing machine (Instron 3365, America) with a deformation rate of 10 mm/min and the gauge length was set at 20 mm.
The water stability and excellent tensile properties of the crosslinked SF nanofiber could be used in a variety of biomedical applications, such as tissue-engineered scaffolds, wound dressings and drug delivery systems.

Functionality is one of key elements in TRIZ that used to build models showing how a system works, as well as how a system creates benefits, harmful effects, and costs.
Concept Design is proposed by Palh & Beitz in its book "Engineering Design" in 1984.
Another problem is that friction wheel maybe soon wear out, so appropriate material should be select.
