Abstract
The invention provides a method for producing warp knitting coralon leather polyester filament. The processed POY protofilament is removed to false twist after being detected and balanced, the process flow is that: POY protofilament - a roller feeding in - a hot box for heating distortion - cooling - false twist - two rollers feeding in - two hot boxes for heating and forming - three rollers feeding out - oiling - DTY winding forming, a pre-network working procedure is added between the ROY protofilament and a roller feeding in. The method solves problem that coralon leather fabric processed by normal polyester has defects of no-soft hand touch, adhesive hair, down pile making, without coralon leather style, and can cover the prior art shortage.
Description
Technical field
The present invention relates to a kind of production method that is used for warp knitting coral velvet polyester filament yarn.
Background technology
Along with the raising of socio-economic development level and living standards of the people, people are not only to the requirement of household lining, clothing fabric that it can be worn can usefulness, and more be comfortableness, the feel degree of seeing it and whether reach vision or haptic effect preferably.
Coral fleece blanket fabrics since between fabric fibre density higher, be coralliform, spreadability is good, and is colorful just as light and soft figure as the coral of living, and can satisfy the demand of present people to household, clothing fabric.
Ordinary polyester DTY product, the soft degree of the coral fleece blanket fabrics that weaves is not enough, easily falls hair or adhesive hair, fails to reach the comfort level and the feel degree of the market demand.Cashmere fabric on the market, its comfortableness, feel degree and vision or haptic effect all can satisfy people's requirement, but owing to its resource is limited to, cost an arm and a leg, and fail to be used widely.
In order to satisfy the more and more higher requirement of consumer, a kind of method of using is to adopt special false twisting processes to become the 167dtex/288f polyester filament 275dtex/288fPOY now, the comfortableness of the lining comfortableness that this polyester filament processes, feel degree and vision or haptic effect style, use can satisfy the characteristics style of coral fleece blanket fabrics, is used for substituting cashmere fabric.Its market prospects are wide, have remarkable economic efficiency.
Summary of the invention
A kind of production method that is used for warp knitting coral velvet polyester filament yarn of the present invention, it is characterized in that spinning process 275dtex/288fPOY, false twisting adopts special process to be processed into 167dtex/288fDTY, POY precursor → roller feeding → one hot case adds that thermal deformation → cooling → false twisting → two rollers feeding → two hot casees add HEAT SETTING → three rollers feeds → oils → the DTY coiling and molding, and the POY precursor has increased network operation in advance between a roller feeds.
A kind of production method that is used for warp knitting coral velvet polyester filament yarn of the present invention, its described processing machine type can be elasticizers such as BARMAG, TMT, RPR, ICBT, process velocity be 400-1000 rice/minute, one heater temperature is 155 ℃～200 ℃, two heater temperatures: 140 ℃～220 ℃, draw ratio: 1.45～2.20, false twisting speed ratio: 1.45～2.20, network air pressure: 0.05～0.15MPA, two overfeedings :-3.0～5.0%; Three overfeedings :-3.0～5.0%, the filament number that is processed into DTY is 0.3dtex～5.6dtex.
A kind of production method that is used for warp knitting coral velvet polyester filament yarn of the present invention, described pre-network are to increase pre-network operation at the POY precursor between roller feeding, and this operation is used the special networks nozzle, adjust the control network pressure at 0.05kgf/cm
2～0.15kgf/cm
2Scope in.Through the processing of pre-network operation, can increase coherent, the drapability of fiber effectively, the polyester filament strand that processes is stood upright, convergence is good, being beneficial to postorder and weaving the fine hair of lining and stand upright, more can satisfy the style of coral fleece blanket fabrics, also is one of main distinction with conventional production process.
A kind of production method that is used for warp knitting coral velvet polyester filament yarn of the present invention, described two hot casees add HEAT SETTING, be that polyester fiber is carried out HEAT SETTING in processing, it can adjust the fine structure of fiber, make it to set up stable shape more, the overall orientation degree and the degree of crystallinity of fiber are improved, the size of crystal region and degree of crystallinity reach a new state, temperature control has bigger influence to stress, raising degree of crystallinity, the crystal size of eliminating fibrous inside, and the heat endurance of fiber significantly improves.It is lower that two heater temperatures of conventional production process are set, and strand easily scatters, adhesive hair, the hair that falls, and fails to reach the requirement of coral fleece blanket fabrics.This method for producing is particularly important to the control of two heater temperatures, need be controlled on the higher temperature value (〉=170 ℃), strand is more abundant through typing after this temperature, DIMENSIONAL STABILITY is better, strand is difficult for scattering, not adhesive hair, do not fall hair, more can satisfy the style of coral fleece blanket fabrics, also be another main distinction with conventional production process.

Fig. 1 is a kind of warp knitting coral velvet polyester filament yarn process chart of the present invention
Wherein 1 is that POY precursor 2 is that pre-network 3 is that first feeding roller 4 is that a hot case 5 is that coldplate 6 is that false twister 7 is that second feeding roller 8 is that middle network 9 is that two hot casees 10 are that the 3rd to feed roller 11 be that oiling roller 12 is DTY reel systems
The specific embodiment
Below in conjunction with the specific embodiment; further set forth the present invention; it is important to point out that following examples only are used for that the present invention will be further described; can not be interpreted as limiting the scope of the invention, the person skilled in art can make some nonessential adjustment according to the content of foregoing invention.These equivalent form of values fall within the application's appended claims institute restricted portion equally.
The present invention is a kind of to be used for the warp knitting coral velvet polyester filament yarn technological process:
POY precursor → roller feeding → one hot case adds that thermal deformation → cooling → false twisting → two rollers feeding → two hot casees add HEAT SETTING → three rollers feeds → oils → the DTY coiling and molding, and the POY precursor has increased network operation in advance between a roller feeds.
As shown in Figure 1, terylene pre-oriented fiber 275dtex/288fPOY precursor 1, enter pre-network 2 by wire leading pipe and carry out pre-network operation, pass through hello the silk and the traction of a roller 3 and two rollers 7 again, make strand add thermal deformation and coldplate 5 cools off, arrive false twister 6 and carry out false twisting processing through a hot case 4; Through the feed wire process of the strand after the false twisting by two rollers 7 and three rollers 10, make strand through in network 8 carry out in the network operation, then add HEAT SETTING by two hot casees 9, entering the rod 11 that oils again oils, arrive reel system 12 at last and carry out the DTY coiling and molding, the finished product that obtains is promptly finished whole processing through behind the test package.Wherein, the speed of a motor vehicle: 680m/min, draw ratio: 1.70, pre-network air pressure: 0.08MPA/0.10MPA, false twisting speed ratio: 1.60, two overfeedings :-3.5%, three overfeedings :-3.8%, one heater temperature: 185 ℃, two heater temperatures: 170 ℃, make 167dtex/288fDTY.
