Description
Technical field
The present invention relates to synthetic fiber technical field, more particularly, it relates to a kind of terylene pre-tropism continuous yarn and manufacture method thereof.
Background technology
Along with improving constantly of social materials educational level, the requirement of people to clothing fabric, ornament materials is abundanter.Natural fabric and tModified Cellulose Fibers are no matter in output or can not meet the growing demand of people qualitatively.Therefore synthetic fiber technology is able to research and development widely, and chemical fibre, through the more function of modified imparting, instead of natural fabric gradually.And terylene is as first synthetic fiber, the multifunctional novel product of the applicable consumer demand of exploitation enjoys the concern of people.
Existing Authorization Notice No. is two-step method preparation technology and the polyester industrial yarn thereof that the Chinese patent of CN1321230C discloses a kind of HMLS terylene polyester industrial yarn, although its polyester industrial yarn prepared has the performance of HMLS terylene rate, its anti-ultraviolet property is bad.
Summary of the invention
For the deficiency that prior art exists, the object of the present invention is to provide a kind of terylene pre-tropism continuous yarn, there is good anti-ultraviolet property and higher fracture strength.
For achieving the above object, the invention provides following technical scheme:
A kind of terylene pre-tropism continuous yarn, in mass fraction, its raw material comprises: fiber level PET polyester sheet 90 ~ 100 parts, cetyl trimethyl silver bromide ammonium 0.1 ~ 0.5 part, 1,1 '-thiobis (beta naphthal) 1 ~ 1.3 part, 2-dihydroxy benaophenonel 0.7 ~ 1.2 part, 0.1 ~ 0.5 part, nickelous EDTA complex compound, preparation medium 2.7 ~ 3.2 parts.
Another object of the present invention is to provide the preparation method of terylene pre-tropism continuous yarn described above, comprise the steps:
Step 1) fiber level PET polyester sheet is cut into slices; It is dry that PET polyester slice carries out first time, and baking temperature is 160 ~ 180 DEG C, and drying time is 30min; It is dry that PET polyester slice carries out second time, and baking temperature is 185 DEG C, and drying time is 4 ~ 6 hours, makes the moisture content≤25ppm of PET polyester slice; PET polyester slice after drying carries out melting, cetyl trimethyl silver bromide ammonium, 1 is added after melting completely, 1 '-thiobis (beta naphthal), 2-dihydroxy benaophenonel, nickelous EDTA complex compound, evenly rear extruded one-tenth silk, cooling to be mixed;
Step 2) by step 1) in the PET Polyester Filament of gained carries out collecting through first roller successively, upper hot case heating, heater twisting, the second roller carry out stretching, lower hot case sizing, the 3rd roller are shaped further, oiling machine carries out refueling, take up roll shaping terylene pre-tropism continuous yarn; Wherein, fill preparation medium in described oiling machine, the speed of production controlling described terylene pre-tropism continuous yarn is 3300rad/min.
Step 1) described in section thickness be 0.5mm.
Step 1) described in the temperature of melting be 280 ~ 290 DEG C.
Step 1) described in cooling adopt ring quenching, wherein wind-warm syndrome is 18 ~ 22 DEG C, relative humidity is 70 ~ 80%, wind speed is 0.4 ~ 0.6m/s.
Step 2) described in the heating-up temperature of upper hot case sizing be 175 ~ 180 DEG C.
In step 1) in gained PET Polyester Filament after, directly carry out step 2) process.
Compared with prior art, the present invention has following beneficial effect:
(1) cetyl trimethyl silver bromide ammonium, silver ion is different with the Antibacterial Mechanism of quaternary ammonium salt, the Antibacterial Mechanism of silver ion is: because silver ion is positively charged, microorganism is generally electronegative, according to the effect of Coulomb attraction, both are attracting, when antimicrobial surface accumulates the anion of the concentration of some, anion just effectively can puncture the cell membrane of microorganism, and penetrate in microbial cell and react with the sulfydryl of protein, microprotein is solidified, protease inactivation, thus make microbial cell lose division, fertility, silver ion also has high reduction potential simultaneously, the space of surrounding can be made to produce elemental oxygen and greatly improve antibacterial effect, and the Antibacterial Mechanism of quaternary ammonium salt is Antibacterial Mechanism: quaternary ammonium salt progresses into cell by antimicrobial surface anion binding, destroys cell membrane, make cell content beyond the region of objective existence rush down and cause cell death, thus suppress microbial reproduction.It is unexpected that discovery cetyl trimethyl silver bromide ammonium can improve the fracture strength of pre-oriented yarn of the present invention, this may be due to degree of crystallinity when cetyl trimethyl silver bromide ammonium can improve spinning, improve the tightness of fibre structure, and then improve the fracture strength of pre-oriented yarn of the present invention.
(2) 1,1 '-thiobis (beta naphthal) is a kind of high-efficiency multi-function antioxidant; 2-dihydroxy benaophenonel is UV absorbers, containing o-hydroxy ketone group in its molecular structure, hydrogen bond ring can be formed in molecule, proton translocation is there is after molecule absorption ultraviolet is stimulated, and its molecule has high conjugated structure, can form resonance stable state, the molecule being in excited electronic state becomes vibrational excitation ground state by power conversion, restores to the original state with the form deactivation of heat release; Nickelous EDTA complex compound is quencher very effectively, can effectively cancellation excitation state carbonyl and singlet-oxygen quenching, and catches free radical; When 2-dihydroxy benaophenonel and nickelous EDTA complex compound share, synergy is produced to uvioresistant aspect, and 1,1 '-thiobis (beta naphthal) has the effect of enhancing to its synergy.
(3) fracture strength of production technology of the present invention to terylene pre-tropism continuous yarn has a great impact, and this all has influence on orientation and the crystallization of terylene pre-oriented fiber, thus the mechanical property of endowing terylene pre-oriented yarn.
