The development status of imitation silk fabric
The development and research of imitation silk fabrics began in the mid-1960s. At that time, the triangular cross-section of fibers and alkali reduction treatment were mainly used to achieve the effect of imitation silk. In the second half of the 1960s, in order to produce products with good drape and fine texture like cross-filament yarn, low-density polyfilament yarn (single teaching around 1.1 dtex) was generally used. The yarn is loose and has grooves. At the same time, during this period, in terms of post-finishing technology, strong twisted crepe fabrics and plain silk fabrics were developed. At that time, polyester ether and casey polymerized propylene fibers were also explored, but no major progress was made. Therefore, judging from the current silk-like materials, polyester fiber is still the main trend. The production technology of the basic style of simulated silk has been basically established in the early 1970s. By the mid-1970s, the beautiful style of simulated silk was more pursued. The primary indicator of the basic style is to have an appropriate sense of looseness, within the fiber or between fibers. There is a certain shrinkage difference between them. Of course, the style of the fabric is not only determined by these factors, but drape, feel, finish, silkiness, etc. are also important factors. In order for the fabric to achieve these excellent quality features, it requires fiber specialization, fiber splicing, etc. The appropriateness must be determined, and in addition, the finishing processes such as machine specifications, coloring, and post-finishing must be strictly controlled. During this period, the basic finishing technology of simulated silk flat silk fabrics and simulated silk strongly twisted crepe fabrics made of polyester filaments was laid. In recent years, imitation silk has made great progress. The use of laminating materials to imitate silk manufacturing technology has been widely used, which has brought about the diversification of fabric styles and appearances. This is reflected in the fact that some imitation silk fabrics are moving towards high-end and are beginning to get rid of the Purely imitating silk fabrics, and further expanding the research into lightweight fabrics for women and other fabrics.
