Example Embodiment

[0042] Example 1:

[0043] The isotactic polypropylene PP with a melt index [MI]=17g / 10min and a PBT-PEG copolyetherester with an intrinsic viscosity of 1.02dl / g and a melting temperature of 202℃ (which is a combination of polybutylene terephthalate and Polyethylene glycol copolymer, the mass ratio of polybutylene terephthalate and polyethylene glycol is 40 / 60); mixed in different proportions, on a single screw melt spinning machine with a diameter of 25mm It melts and mixes uniformly, and then the blended melt is sent to the spinning assembly by the metering pump in a prescribed amount and extruded. After cooling, oiling, and winding, the raw fiber of the blended fiber is obtained; the raw fiber is then in accordance with the BCF (Spinning-stretching-deformation one-step method to prepare bulked filaments) The finished fiber is obtained through stretching, shaping, and deformation processing.

[0044] The number of holes in the spinneret is 24, the hole diameter is 0.30mm, and th...

[0056] Example 2:

[0057] Pre-dried 12 parts (parts by mass) of PBT-PBG copolyetherester (copolymerization of polybutylene terephthalate and polybutylene glycol) with an intrinsic viscosity of 1.05dl / g and a melting temperature of 210°C The mass ratio of hard segment / soft segment is 45 / 55) and 88 parts (mass parts) of PP (MI=35) slices are uniformly mixed, and then melted in a single-screw melt spinning machine with a diameter of 30mm, and then The metering pump sends the blended melt to the spinning assembly in a prescribed and quantitative manner to obtain the original fiber of the blended fiber after extrusion, cooling, oiling and winding; the original fiber is stretched and shaped to obtain the finished fiber. Spinneret hole number 24, pore diameter 0.25mm, aspect ratio 2, spinning temperature 236℃, winding speed 2200m / min, stretching temperature 70℃, setting temperature 125℃, stretching ratio 2.4 times.

[0058] Fiber breaking strength 3.4cN / dtex, breaking elongation 21%; fi...

[0062] Example 3:

[0063] The PP chips with [MI]=23 were blended with the pre-dried copolyetherester chips with the same ratio as in Example 2 at 92 / 8 (wt), and melt-spinning was performed on the same equipment as in Example 1. The spinning speed is 650m / min, and then it is stretched and shaped, and the specific resistance of the blended fiber is 5.5×10 11 Ω·cm, after the disperse dye is boiled and dyed at normal pressure, the specific resistance value of the fiber drops to 2.1×10 10 Ω·cm.

Abstract

The invention relates to a mekralon with dyeing and antistatic property. The mekralon is prepared by at least one dyeing polymer composition spinning with polypropylene composition, wherein, weight rate of dyeing polymer composition and polypropylene composition is 1:1.5-1:35; the dyeing polymer composition selects at least one of multipolymer composed by poly terephthalic acid dihydric alcohol ester and poly dihydric alcohol. The mixing fiber together can spin long fibre, short fibre that are used as woven fabric, knitted fabric, non-weaving cloth or carpet yarn with better hydroscopic property, soft handle sense, antistatic property and high dyeing property fastness.

Description

technical field [0001] The invention relates to a dyeable and antistatic polypropylene fiber, in particular to a hygroscopic, dyeable and antistatic polypropylene fiber prepared by blending spinning of pure high polymer and polypropylene without carbon powder and other conductive inorganic materials . Background technique [0002] As we all know, polypropylene fiber has good chemical stability, anti-fouling and abrasion resistance, light weight and good heat retention, and fine-denier polypropylene fiber also has excellent moisture conductivity and perspiration, so it has been widely used. However, polypropylene fibers also have certain defects, such as inability to dye, poor hygroscopicity, and easy generation of static electricity, which limit its further development and application. [0003] The research on the modification of polypropylene fibers has aroused widespread interest. People have made a lot of efforts to improve the comprehensive properties such as dyeing pe...
