Chemical synthesis and fermentive method is the major industrial way to produce DHS, and microbial rational modification based on the development of metabolic engineering made the fermentive method more widely used.

工业上一般采用化学合成法和发酵法来生产3-脱氢莽草酸，随着代谢工程的兴起，使得更加理性改造菌株成为可能，这更加促进了发酵法的广泛应用。

It is as soft as nylon and as fluey as acylic.PTT possesses the many advantages of many synthetic fibers and these advantages make its application widly. Currently, the protucts of PTT include carpet, garment, plastic and so on. This paper is about the application of filament CM800 in knitted underwear fabrics. Filament CM800 is bi -component fibers with excellent elastic recovery. According to the performance of knitting fabrics, the relationship of knitting technique and wearablity is researched by orthogonal methods.

与常规化纤相比，PTT纤维具有突出的化学稳定性、回弹性，较好的染色性和色牢度以及良好的抗污性，它综合了锦纶的柔软性、腈纶的蓬松性、将多种纤维的优良性能集于一体，这些优势使它具有广阔的应用空间，目前PTT的产品主要涉及地毯领域、服装领域和工程领域等。
