Ptt fiber is the english abbreviation of poly terephthalic acid 1.3 propylene glycol ester fibers, is the new type polyester fiber of being made by PTA and PDO polymerization, spinning from petroleum technology route and biology corn process route respectively by ShellChemical (shell chemical company) and du pont company the earliest.Ptt fiber has the characteristic of terylene, polyamide fibre, acrylic fibers concurrently, except that antifouling property well, be easy to dyeing, soft, high resilience in addition, extensibility is equally good with spandex fibre, compares with the elastomer spandex to be easier to processing, is fit to very much the textile garment lining; PTT also has characteristics such as dry and comfortable, well-pressed in addition.PTT is fit to pure spin or compound with cellulose fibre and natural fabric, synthetic fiber, produces carpet, plain clothes, fashionable dress, underwear, sweat shirt, swimsuit and socks.

Cladded yarn is a kind of widely used functional yarn, and processing is easy, combination is various owing to have, thereby adopts in a large number in textile industry, also has a lot of patents to deliver simultaneously.Such as: Chinese patent CN2876118 discloses a kind of cladded yarn that is used for non-ironing environment-friendly plus material, comprise long filament component as heart yearn, as the short fiber component on top layer, described long filament component is polyester filament or a nylon monofilament between 20 dawn and 60 dawn between 20 dawn and 60 dawn.The cladded yarn that is used for non-ironing environment-friendly plus material of the utility model patent, because adopt polyester filament as heart yearn, and the radical of polyester filament has guaranteed the rigidity of polyester filament between one, two, three, the skeleton effect is obvious, and the lining that is made into possesses natural wrinkle properties.

Along with improving constantly of living standards of the people, people are not only attractive in appearance, endurable to the requirement of dress ornament, but more and more pay attention to comfortableness.Heteromorphosis and functionalization are the focuses of current chemical fibre development.The clothes that the various fibres in differentiation that continued to bring out are in recent years made more and more are subjected to consumer's favor.

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.
