According to the characteristics of spandex engineering process,introduces the design principles and configuration of air conditioning and ventilation systems.

On the basis of polyurethane fibre's characteristics and usages,the paper introduces the present market situation and prospects of the development of polyurethane fibre in China.

Proceeding from the property of elastic fabric made of real silk/polyurethane fibre covered yam and its weaving requirements, the paper makes systematic property tests of some real silk/polyurethane fibre cov-ered yarns, and suggsts requirements meeting the weaving technology and yam property indexes ensuring fabric quality.

Entangled composite yarn with excellent elasticity and extensibility can be developed by compounding real silk and polyurethane fibre, and further processed into woven or kted fabrics.
