Abstract
The invention discloses a method for showing the elasticity of polytrimethylene terephthalate/polyethylene terephthalate (PTT/PET) composite filaments. The method comprises the following steps of: taking parallel-type PTT/PET uncolored or colored composite filaments obtained by a pre-oriented yarn-draw texture yarn (POY-DTY) process or a full drawn yarn (FDY) process as a raw material, wherein the constituent ratio of the two components is 40/60 to 60/40; balancing the parallel-type composite filaments for 8 hours at the temperature of 20+/-3 DEG C and the humidity of 60+/-5 percent; passing the parallel-type composite filaments in and out a constant temperature hot box at the temperature of 165-200 DEG C at the speed ratio of R1 (R1 is 1.01-1.18) after unwinding; and winding and molding at the speed ratio of R2 (R2 is 0.965-1.0) and the winding speed of 200-500 m/min to obtain elastic self-crimping PTT/PET composite filaments. The prepared elastic PTT/PET composite filaments have very high flexibility without heat treatment, can be directly used for cotton, wool and silk blended elastic fabrics, save a moist heat treatment process of composite fabrics, and widen the application field of the PTT/PET composite filaments.
Description
Technical field
The invention belongs to the technical field that fiber filament curls, relate to the treatment technology that two kinds of different fibers curl and finalize the design.Also relate to simultaneously manufacturing with elastic fabric.
Background technology
PTT (the abbreviation of polytrimethylene terephthalate, down together)/PET (polyethylene terephthalate, abbreviation, down together) bicomponent filament yarn is as a kind of novel elastic fiber material, given full play to the good characteristic of PET, PTT long filament, and the three dimensions crimp property that never has when producing both individualisms, remedy the defective of one-component on performance.The characteristics of PTT/PET bicomponent filament yarn maximum are to utilize the bigger thermal contraction performance difference of existence between PET component and PTT component, after heat treatment process such as dyeing and finishing, form the woolly thin and close wrapped configuration of class, thereby obtain better elastic and bulkiness, as Wang Chenghu etc. with PET/PTT bicomponent filament yarn and cotton blending, the indexs such as elastic recovery rate [1] of dyeing back fabric have been discussed, PET/PTT bicomponent filament yarns such as Luo Jin will be put into electric-heated thermostatic water bath, boiling water heat treatment 15min under the relaxed state, with the fiber that dries after handling in thermostatic constant wet chamber (temperature (20 ± 2) ℃), relative humidity (65 ± 3)) inner equilibrium 24h. has tested the correlated performance [2] of fiber then.The long filament elasticity of Xiao Hong DIFFERENT WET heat treatment process is the basis that fabric elasticity is realized, the heat endurance of different disposal process flexibility fabric also is to use the focus in the process, and these also need further discussion [3].Sun Hong etc. point out that also the characteristics of PTT/PET composite fibre maximum are to utilize it to have different thermodynamic behaviours, after the dyeing and finishing heat treatment process, can form the woolly thin and close wrapped configuration of class, thereby obtaining better elastic and bulkiness [4]. the PET/PTT bicomponent filament yarn that gets off from spinning threadling is because stress relaxation, have less and sparse curling, have only by further heat treatment to discharge its potential curling potential energy, realizing curling manifests, and could obtain desirable curling elasticity.The conventional application technology of PET/PTT bicomponent filament yarn is to be that warp thread, PET/PTT bicomponent filament yarn are weft yarn with cotton yarn or polyester filament, obtains elastic fabric through the hot wet process more than 100 ℃ again.PTT/PET bicomponent filament yarn elasticity provided by the invention can make fiber promptly have good elasticity without heat treatment process such as dyeing and finishings from the technology of showing, can substitute spandex direct and look silk, wool and silk blend acquisition elastic fabric, saved the heat treatment step of fabric, reduce production cost, enlarged the Application Areas of PTT/PET bicomponent filament yarn.
