Embodiment 1

[0032] Using ethylene glycol and terephthalic acid (the molar ratio of ethylene glycol and terephthalic acid is 1.3:1) as raw materials, it is produced in a semi-continuous direct esterification device at 258°C after 2.5 hours to complete the esterification reaction. Ethylene terephthalate. Then add the diethylene glycol isophthalate-5-sodium sulfonate of 4.5mol% (in total moles of terephthalic acid) prepared in advance, 0.45mol% (in total mass of terephthalic acid) ) polyethylene glycol and 1.5% (based on the total mass of terephthalic acid) ground inorganic nanopowder SiO 2 , at 0.032wt% catalyst Sb 2 o 3 The polycondensation reaction is completed in the presence of (based on the total mass of terephthalic acid), the residual pressure of the system is less than 80 Pa, and the final reaction temperature is controlled at 282°C. The power of the mixer in the reaction process is controlled to obtain a functional copolyester masterbatch with an intrinsic viscosity of 0.535dl / g...

Embodiment 2

[0038] According to the mol ratio of ethylene glycol and terephthalic acid in Example 1, the esterification and polycondensation process conditions are the same as in Example 1. Diethylene glycol isophthalate-5-sodium sulfonate, 0.55mol% (total mass of terephthalic acid) Polyethylene glycol and polytetramethylene glycol (the two add in equimolar ratio) mixture, and 1.3% (in terms of the total mass of terephthalic acid) inorganic nano-powder ZrO after grinding 2 , to prepare a functional copolyester masterbatch with an intrinsic viscosity of 0.526dl / g.

[0039] The obtained above-mentioned functional copolyester masterbatch is mixed with conventional polyethylene terephthalate (PET) slices with an intrinsic viscosity of 0.665g / dl in a mass ratio of 20:80, pre-crystallized, and dried , and then carry out blending spinning-stretching-heat setting on the ordinary short fiber melt spinning machine and post-processing equipment to make trilobal special-shaped short fibers. The spi...

Embodiment 3

[0043] According to the mol ratio of ethylene glycol and terephthalic acid in Example 1, the esterification and polycondensation process conditions are the same as in Example 1. Diethylene glycol isophthalate-5-sodium sulfonate, 0.40mol% (total mass of terephthalic acid) Polyethylene glycol and polypropylene glycol (the two add in equimolar ratio) mixture, and 1.2% (in terms of the total mass of terephthalic acid) inorganic nano-powder TiO after grinding 2 , to prepare a functional copolyester masterbatch with an intrinsic viscosity of 0.551dl / g.

[0044] The obtained above-mentioned functional copolyester masterbatch is mixed with conventional polyethylene terephthalate (PET) slices with an intrinsic viscosity of 0.665g / dl in a mass ratio of 30:70, pre-crystallized, and dried , and then carry out blending spinning-stretching-heat setting on the ordinary short fiber melt spinning machine and post-processing equipment to make five-lobed special-shaped short fibers. The spinni...

Abstract

The invention discloses a modified polyester fiber prepared by carrying out blended spinning on functional copolyester master-batches containing moisture-absorbing radicals and inorganic nano-powder and conventional polyester chips, the section of the fiber is special-shaped and comprises micropores, the side surface of the fiber comprises a structure of longitudinal grooves and micro-pits, and a variety of fabric can be prepared by carrying out the blended spinning on the modified polyester fiber and natural fiber according to weight proportion. The fabric has the excellent functions of wetting by sweat, moisture transmitting and quick drying, thereby greatly improving the wearing comfort of the polyester fiber fabric.

Description

technical field [0001] The invention relates to a polyester fiber for preparing functional fabrics with excellent sweat wettability, moisture conduction and quick drying. It belongs to the field of textile fibers. Background technique [0002] With the continuous development of society and the continuous improvement of people's living standards, people's demand for clothing materials is getting higher and higher, and it has developed to not only require physical comfort (thin, warm, cool), but also psychological comfort ( Visual tone gloss, tactile feel, softness, bulkiness, drapability), also need certain special functionality. Polyester fibers for fast moisture absorption, moisture conduction, quick drying, antistatic, anti-ultraviolet and anti-pilling fabrics have attracted more and more attention. [0003] Since the advent of polyester fiber, it has been widely used in clothing textiles for its good drapability, high strength, excellent wrinkle resistance and washable ...
