Problems solved by technology

Among them, nylon is the most suitable material for carpets, but it has the disadvantage of high price, so inexpensive polypropylene is used as a substitute
[0003] However, since polypropylene is not suitable for use in high-temperature molded car carpets due to its low heat resistance, low-quality but inexpensive needle-punched nonwovens are often used
However, since needle-punched non-woven fabrics have the disadvantages of lower appearance quality than tufted carpets and poor abrasion resistance, it is necessary to develop inexpensive tufted carpet materials.
[0004] In recent years, in order to solve the above-mentioned problems, attempts have been made to adopt BCF as a carpet for automobiles by using a polyethylene terephthalate material that has excellent characteristics compared with other materials in terms of economy and has high heat resistance BCF, but polyethylene terephthalate is high in weight relative to nylon, so it has a disadvantage in terms of price, because the implanted yarn weight per unit area must be increased to produce the same appearance
In addition, since the bulk stability of the yarn is lower than that of nylon, there is a problem that the yarn is compressed after molding and the sense of volume decreases.

Embodiment 1

[0050] A slurry prepared by mixing 50 parts by weight of ethylene glycol and 100 parts by weight of terephthalic acid was added to an esterification reactor and pressurized at 250° C. under a pressure of 0.5 Torr for 4 hours, so that water flowed out of the reactor and the esterification The reaction proceeds, thereby producing (2-hydroxyethyl)terephthalate. At this point, 300 ppm of phosphorus heat stabilizer was added at the end of the esterification reaction. After the esterification reaction, 300 ppm of an antimony catalyst was added as a polymerization catalyst at the beginning of the polycondensation reaction, and the temperature was increased from 250°C to 285°C at 60°C / hr, and the pressure was reduced to 0.5 Torr. Solid phase polymerization is performed to increase the viscosity of the liquid polymer. Typically a batch solid phase polymerizer is used during the solid phase polymerisation process to dry under vacuum at 140°C for 4 hours. The temperature was increased ...

Embodiment 2 and 3

[0053] The polyethylene terephthalate BCF yarn was prepared by the same procedure as in Example 1, except that the yarn was rapidly made at the outlet of the texturing nozzle with cooling air or cooling water at the temperature and pressure shown in Table 1 below. cool down.

Embodiment 4

[0055] A polyethylene terephthalate BCF yarn was prepared by the same procedure as in Example 1, except that the yarn was cooled by sucking air through a cooling drum placed within 1 cm slightly below the texturing nozzle to quench the air, whereas Instead of cooling the yarn with cooling air at the exit of the texturing nozzle.

Abstract

A tufted carpet for an automobile includes: a pile layer including polyethylene terephthalate (PET) bulked continuous filaments (BCF); and at least one backing layer, wherein the crimp ratio of the bulked continuous filament is 14% or more and the cross-sectional correction ratio is 1.9 to 3.4.

Description

technical field [0001] The present invention relates to bulked continuous filaments of polyethylene terephthalate suitable for use in automobiles and tufted carpets comprising the filaments. Background technique [0002] Generally, nylon 6, nylon 66, polypropylene, polyethylene terephthalate, and the like are used as the synthetic fiber material of the bulked continuous filament (BCF) which is a material of the tufted carpet. Among them, nylon is the most suitable material for carpets, but it has a disadvantage of being expensive, so inexpensive polypropylene is used as a substitute. [0003] However, since polypropylene is not suitable for use in high-temperature molded car carpets due to its low heat resistance, low-quality but inexpensive needle-punched nonwovens are often used. However, since the needle-punched nonwoven fabric has disadvantages of lower appearance quality than tufted carpets and poor abrasion resistance, it is desired to develop an inexpensive tufted ca...
