Advantages, characteristics and uses of polyester fiber Polyester It has many excellent textile properties and wearability. It can be used for pure weaving. It can also be blended with natural fibers and other chemical fibers such as cotton, wool, silk, hemp and other chemical fibers. It can ...
The present invention relates to a process for preparing a polyester with improved fusion properties and crystallization characteristics, comprising the steps of:a. production of a pre - polyester melt with an average molecular weight (mn) of 2000 to 16000 g / mol,example, consolidating and molds...
Common varieties are polyester silk, polyester crepe, polyester satin, polyester, and polyester interlaced silk. These varieties of silk fabrics are elegant, pendulous, slippery, soft, and pleasing to the eye. At the same time, they also have the properties of crisp, wearable, easy to wash and...
A number of variations of the basic repeat are available but they vary primarily in terms of the proportion of the aromatic and the aliphatic components and, as a result, lead to fibers with different physical and mechanical properties. Some low molecular weight aliphatic polyesters are used as ...
PROBLEM TO BE SOLVED: To provide a biaxially stretched polyester film excellent in moldability at a time of the molding of a can or the like and also excellent in heat resis tance, impact resistance and taste characteristics by setting a... 高橋 弘造,木村 将弘,阿部 晃一 被引量: 0发表...
000 molecules and are used in the synthesis of flexible PU, while the lower molecular weight polyols typically include less than 2000 particles used in the production of rigid PU.Table 2shows the structure of common types of polyols andTable 3shows a variation of the properties of PU due to...
Acritical review: the ring-opening polymerization of cyclic esters provides access to an array of biodegradable, bioassimilable and renewable polymeric materials. Building these aliphatic polyester polymers into larger macromolecular frameworks provides further control over polymer characteristics and opens up ...
The structure of the essential cell wall of these fibres, and especially the external surface cuticle layer, has a significant effect on fibre characteristics. One of the unique cotton fibres is the Egyptian cotton, which is dominant among other types of cotton fibres due to a variety of ...
