Because production technology, the particularly production technology of its raw material PDO of ptt fiber are grasped abroad basically as in trans-corporation's hands such as Du Pont or shell, so its production cost is higher, causes the application of PTT to be subjected to very big restriction.Domestic general textile enterprise adopt the PTT short fiber with other as numb, close short fiber blending such as fibre, cotton or PTT long filament and other long filament interweaving method and use the PTT product, also played achievement preferably.
Summary of the invention
The purpose of this utility model is to provide a kind of elastic memory yarn, and its main raw material composition is the PTT long filament, and this yarn is except that the good characteristic with PTT, and main purpose is to reduce production costs, and also has other performance simultaneously.
For achieving the above object, the technical solution adopted in the utility model is: a kind of elastic memory yarn, have the architectural feature of cladded yarn, and comprise as the PTT long filament component of heart yearn and as other fibre fractionations on top layer; Described other fibers comprise one or both of zein fiber, day bamboo fibre or viscose; Described other fibers be shaped as a kind of in staple fibre, multi-filament and the one filament; Described PTT long filament is a kind of of FDY or DTY, specification (15~340) dtex/ (1~288) f.
The beneficial effects of the utility model show: owing to adopted PTT long filament to make heart yearn with superior elasticity and shape memory function, so fiber a kind of yarn of elastic memory preferably of still can yet be regarded as; No matter three kinds of fibers of outsourcing simultaneously select a kind of still two kinds or any combination wherein for use, all can promote other function of yarn greatly, are embodied on the fundamental characteristics of these several fibers:
1, zein fiber is to be raw material with starch such as corn, wheats, changes into lactic acid again through polymerization through fermentation, spinning and the synthetic fiber made.This fiber has biodegradability, and fiber is softly sliding suitable, and intensity is big, and moisture absorption is ventilative, and product processed has gloss as the silk and comfortable skin sense of touch and feel, and drapability is good, good heat resistance and anti-ultraviolet function, and wearability is good.It has the advantage of synthetic fiber and natural fabric concurrently, and the while is complete Natural Circulation type of tool and the biolytic characteristics of energy again.
2, it bamboo fibre is to be raw material with the bamboo that the land of plenty abounds with, through special high-tech PROCESS FOR TREATMENT, cellulose in the bamboo is extracted, again through glue, the regenerated celulose fibre that operation manufacturings such as spinning form, it is day silk that continues, soybean fiber, another fabric raw material after the products such as chitin fiber, it has soft, drapability is good, moisture absorption and desorption property is good, characteristics such as it is beautiful to dye, especially unique is antibiotic, antibacterial, antiultraviolet and be easy to biodegradation and environment do not polluted characteristic makes it be widely used at field of textiles.
3, viscose is to be raw material with the native cellulose, makes the soluble cellulose xanthate acid through operations such as alkalization, aging, yellows, is dissolved in sig water again to make viscose glue a kind of regenerated celulose fibre of making through wet spinning.Be commonly called as artificial cotton, artificial wool and artificial silk, thereby have the correlated performance of natural fabrics such as cotton, hair, silk, such as high-hygroscopicity, soft hand feeling and good sense of touch etc.
The characteristic and the cost advantage of comprehensive these three kinds of fibers, thereby the utility model has PTT long filament better elastic, restoring force and shape-memory properties concurrently, the skin-friendly that zein fiber is good, moisture transported permeable, shape stability, the natural antibacterial function that it bamboo fibre is good or high-hygroscopicity, soft hand feeling and the sense of touch etc. of viscose, the while has also been reduced the production cost of pure PTT yarn and fabric thereof.
