Abstract
The invention relates to an ultra-strong reflecting low stretch yarn and a preparation process thereof. The ultra-strong reflecting low stretch yarn and the preparation process thereof are formed by specially designing a series of ultra-strong reflecting low stretch yarn preparation process steps, including preparation of raw materials, pretreatment, spinning, post-treatment and the like and specially optimizing relevant parameters, so that the ultra-strong reflecting low stretch yarn has better effects on the aspects of quality, color and luster and low elasticity.
Description
Technical field
The present invention relates to a kind of strong reflecting low-stretch yarn and processing preparation technology thereof.
Background technology
We know, for improving polyester fiber moisture absorption, water vapour permeability, do a lot of work in Japan and Taiwan, according to patent report in the past, two research peak periods occurred, first research peak period is nineteen eighty-two-1986 year, mainly is with the polymerization methods synthetic copolyester during this, then directly carry out spinning with copolyesters, or carry out again spinning after mixing by copolyesters and conventional polyester; Second research peak period is nineteen ninety-five, mainly is to add the hole plasticizer with synthetic batching or in mixing mode, again via alkali treatment processing, makes fiber produce hole.
Released the little porous fibre first generation of hollow product patent in 1986 such as Japanese Supreme Being people company, its commodity are called WellkeyFilament, its preparation is the microphase-separated principle of utilizing conventional polyester and hole plasticizer, then after making high orientation silk HOY (Highly oriented yarn) via high-speed spinning, give again suitable alkali treatment and be prepared from.Japanese Supreme Being people of while company also utilizes unique chemical method, silk-fibroin with a kind of high-hygroscopicity material, be coated on the hygroscopicity fibre, develop " moisture-absorbing fibre ", this kind fiber called after WellkeyMA fiber, the absorbing sweat/fast dry characteristic of its fabric is than strong ten times in conventional polyester fabric, but its hollow rate is not high, between 5-10%.In addition, the nineties in 20th century is developed the dry and comfortable fiber of the many micropores of hollow at the Industrial Technology Research Institute of Taiwan chemical industry place, trade (brand) name Hydropre, and it adopts special spinning process, allows the inside and outside tube wall of fiber all have elongated groove, by these grooves and hole moisture absorption, thoroughly wet.But polyester fiber only has moisture absorption, wet effect is far from being enough thoroughly.Above-described all patents are only improved emphatically the moisture absorption of polyester fiber, ventilative, comfort type, further do not improve other functions of fiber.Certainly, the many microporous fibres of hollow are because owing to have copolyesters or synthetic batching or pore former, and the difficult control of spinning technique, is taken in the process easily fibrillation at the finished silk strength decreased, functional after-finishing is difficult for carrying out, also certainly will be relatively more difficult and give functional form before fibroblast.
Along with the raising of people's living standard, various comfortablenesses, health functional fibre emerge in an endless stream.Can produce so both had moisture absorption, saturating wet effect, the fiber that the manifest function health properties is arranged again? at first, because the many microporous fibres of hollow are just wayward by hollow type spinnerets spinning technique itself by two kinds of component slices, moreover after adding function modified master batch, require stricter to spinning and aftertreatment technology.At present, there is no the report of this respect both at home and abroad.
Summary of the invention
The objective of the invention is for above-mentioned deficiency, a kind of particular design from a series of strong reflecting low-stretch yarn step of preparation process such as raw material preparation, preliminary treatment, spinning, post processings and the special optimization of relevant parameter are provided, form a kind of strong reflecting low-stretch yarn and processing preparation technology thereof, reach its better effect of performance aspect texture, gloss, low elasticity.
