Abstract
The inventive technological process for producing a fire retardant abnormal contraction fibre, can produce terylene fabric with high fire retardant performance (Loi larger than 27) and high abnormal contraction performance, which satisfies the requirement of people. The high fire retardant FDY and low fire retardant FDY can produce two FDY retardant fibres with different contraction performances, the compound convolution is carried out through a small bal filling machine. the produced fabric has soft handle, fullfilled luster, good soft nap feeling, elegant performace, excellent clothing performace and especial fabric.
Description
Technical field
The invention belongs to the textile chemical fiber field of production, be specifically related to the production method of terylene fire resistance fibre compound silk.The present invention is to provide a kind of chemical fibre technology.
Background technology
Development along with modern technologies, with people's serial textiles closely bound up, that closely link to each other of living, comprise drapery, bedding, adornment, case and bag articles for use, tent, parachute kit etc., require it aspect functional, bigger improvement to be arranged, flame retardant polyester fiber is owing to have fire-retardant high security, and present stage more and more is widely used, and the different contractile filaments of terylene is composited by the silk of two kinds of different shrinkage degrees simultaneously, its fabric has good hand feeling, velvet and elegant property.Fire-retardant different contractile filaments has had both fire-retardant and different contraction two big functions, is real intelligent multi-function fiber.Therefore the present invention is to provide the chemical fibre technology that fire-retardant different contractile filaments is washed in a kind of production.
Summary of the invention
Purpose of the present invention provides a kind of process of producing flame-retardant different shrinkage fiber, can produce (Loi＞27) and the polyster fibre of high different shrinkage of high flame resistance, satisfies people's needs.
The technology of the present invention is constructed as follows: a kind of process of producing flame-retardant different shrinkage fiber.
Its production technology is:
The fire-retardant FDY of high contraction
Fire-retardant slice feeds intake, and------crystallizing bed------screw extruder fusion one melt pre-filtering and pipeline distribute, and------------oil tanker oils, and---GR1's assembly---GR2----network---reels melt-stoichiometry main drying tower in the lateral blowing cooling in transportation
The fire-retardant FDY of low contraction
Fire-retardant slice feeds intake, and------crystallizing bed------screw extruder fusion one melt pre-filtering and pipeline distribute, and------------oil tanker oils, and---GR1's assembly---GR2----network---reels melt-stoichiometry main drying tower in the lateral blowing cooling in transportation
By above 2 kinds of process routes, can make the FDY fire resistance fibre of two kinds of different contractive effects, carrying out compound coiling through too small elasticizer.
The present invention program's progressive effect is, fabric has soft, is rich in gloss, and good velvet is arranged, and elegant property has good wearability and special fabric simultaneously.
The specific embodiment
1. the selection of fire-retardant slice raw material
What we adopted is the fire-retardant slice that certain company's copolymerization method is produced.Copolymerization method is that the compound that contains ignition-proof elements such as phosphorus, halogen, sulphur is introduced in the macromolecular chain of fiber-forming polymer as comonomer (reactive flame retardant), and then this fire-retardant fused mass is made section through after the pelletizing.Inherent viscosity 0.640, fusing point 239 ~ C, end carboxyl 23mol/t, 0.8/mg of aggregated particle, moisture 0.21%.
2. two kinds of contractile filaments technology controlling and process difficult points
Superelevation contractile filaments and former in general sense the contractile filaments of low powerful high elongation are different, and its brute force elongation is similar with conventional drafted fibre, and its boiling water shrinkage is more high than conventional drafted fibre, can reach 3～5 times of conventional drafted fibre.Carry out the compound different contractile filaments that makes with this superelevation contractile filaments product and conventional drafted fibre, this technology mainly is that the boiling water shrinkage of 2 kinds of contractile filaments is controlled, and multiple preferably is controlled at about 5 times and is advisable.Kind is: 83dtex/72f
