Definitions

  • the present invention relates to a method of preparing non-woven fabric for base cloth of carpet, which has an improved fixability of BCF (bulked continuous filament) yarn inserted on a base cloth in a tufting process for manufacturing a carpet.
  • BCF bulk continuous filament
  • Carpets are used not only for decoration in hotels, offices, homes, cars, but also for providing amenity and sound insulation.
  • the carpet fabric is manufactured through a process including a tufting step of introducing BCF yarn to a non-woven fabric and a back coating step of coating a solution such as PVC, PE, EVA or SBR, etc. the back side of the tufted non-woven fabric and curing.
  • the carpet fabric is cut into squares (for example, 50 cm ⁇ 50 cm) to be used as tile carpets in hotels, offices, homes, etc., and molded in the form of a car floor to be used as a car floor mat.
  • the function of the base cloth of carpet is to fix the BCF yarn.
  • the base cloth is punctured by a needle to have open hole of at least 160,000 holes/m 2 .
  • the base cloth must maintain the arrangement of the BCF yarns in even though such physical damage and have no deformation of the shape in the post-process at the high temperature environment.
  • Recent trends in the tufting process are densification, diversification of pattern and the use of low denier BCF. For example, there is a tendency to increase the tufting density by using microfibers of BCF yarns, to make at least three BCF yarns at multilevel conditions, and to increase the movement of needles by using BCF yarns of various colors. Tufting becomes more difficult. Accordingly, the fixability of the BCF yarn in the non-woven fabric for base cloth has to be improved by increasing the coefficient of friction between the non-woven fabric and the BCF yarn so as to prevent the damage to the base cloth.
  • conventional non-woven fabric for base cloth of carpet is produced by stretching and a thermal or chemical bonding of the filaments having potential stress. After that the residual stress of the filament is removed by heating in the post-processing for the manufacture of carpet, thereby exhibiting a high shrinkage ratio. Due to this, there is a problem that the shape of the final carpet product is deformed.
  • the present invention provides a method of preparing non-woven fabric for base cloth of carpet, which has an increased fixability of BCF by improving a method of preparing non-woven fabric for base cloth of carpet.
  • the present invention provides a method of preparing non-woven fabric for base cloth of carpet comprising: preparing stretched polyester filament fiber having circular cross section; forming a web by integrating the filament fiber in a web form, crimp processing and calendering it; and needle punching the web.
  • the web with the stretched polyester filament is crimp processed and needle punched.
  • the residual stress of the stretched polyester filament is eliminated and the formability is improved, and the fixability of the BCF yarn can be improved by interlacing polyester filament.
  • the present invention relates to a method of preparing non-woven fabric for base cloth of carpet comprising: preparing stretched filament to form a web, crimp processing and calendering and needle punching the web.
  • the present invention may use filament fibers having a circular cross section and a low fineness such as 4 to 7 deniers, which is produced by melting a polyester having a melting point of at least 250 °C, discharging it through a spinneret to form a filament and stretching the filament to a spinning speed of 4,500 to 5,000 m/min using an air stretching device of high pressure.
  • the fineness when the fineness is less than 4 deniers, the damage of fibers occurs during tufting and the fixability of the BCF yarn may be deteriorated, and when the fineness is more than 7 deniers, the coefficient of friction may be lowered and it can be difficult to improve the pullout strength.
  • the flexibility of the filament may be given by piling up the filament fibers on the conveyor in the form of a web and heating and crimp processing them.
  • the crimp processing is a processing method of heat treatment of synthetic fiber filament to form a thin curvature, and the yarn becomes curl and flexible accordingly.
  • the stretched filaments may be piled up on a conveyor net and at the same time, be treated at 100 to 150 °C for 30 to 60 seconds.
  • the shrinkage rate of the filament is lowered and the shape stability can be improved. Further, since the filament constituting the non-woven fabric is provided with a crimp and has a high coefficient of friction, and finally the fixability of the BCF yarn can be improved.
  • the number of crimps of the polyester filament fiber in the crimping process is preferably 20 to 40 /inch. At this time, if the number of crimps is less than 20 /inch, the contact points between the filaments are decreased and the strength and elongation of the non-woven fabric after calendering or needle punching are lowered, and the force to fix the BCF yarn after tufting is weakened. When the number of crimps exceeds 40 /inch, the contact points become too large and the filaments may be damaged due to excessive adhesion between the filaments during needle punching and the coefficient of friction of the non-woven fabric is too high, thus BCF yarn with a low fineness may be damaged when tufting.
  • a non-woven fabric in which interlacing is formed between the filaments can be produced by passing crimp processed web through a calendering roll to adjust its thickness and needle punching it.
  • the calendering of the present invention has a thickness of 0.35-0.50 mm by applying a predetermined temperature (130-150 °C) and pressure to reduce the thickness of the non-woven fabric. Accordingly, the density increases and the amount of filament for interlacing increases.
  • the needle punch is performed in two steps.
  • the first step pre-punching
  • the second step main punching
  • the filaments are interlaced entirely with a condition of 600 to 800 stroke rpm to produce a non-woven fabric for base cloth of carpet.
  • the potential stress of the amorphous region oriented in the stretched filament is eliminated by the crimp processing.
  • the shrinkage rate is reduced due to heat and the curvature is formed to increase the interlacing point of the filament.
  • increased tensile strength and tear tension of the non-woven fabric may exhibit in the needle punching process.
  • PET Polyethylene terephthalate
  • the crimp processing was performed such that the filament fiber was piled up on a conveyor net in form of a web and simultaneously the stacked filament was heated at 130 °C for 60 seconds to form a crimp number as shown in the following Table 1.
  • the calendering was carried out by passing through a heated calendering roll to have smoothness and appropriate thickness to the non-woven fabric.
  • a non-woven fabric for base cloth of carpet was prepared by the same method as the Example 1, except that crimp processing and needle punching were carried out in the conditions shown in Table 1 in the Example 1.
  • a non-woven fabric for base cloth of carpet was prepared by the same method as the Example 1, except that crimp processing and needle punching were carried out in the conditions shown in Table 1 in the Example 1.

  • KS K 0521 method was used.
  • the non-woven fabric is preheated at 180 °C for 3 minutes in a preheating plate and the molding is performed using a square mold having a size of 20 cm x 20 cm with the engraved lower plate and the embossed upper plate.
  • the number of lattice patterns at the torn portion in the non-woven fabric was counted to obtain the width of the torn portion.
  • Loft type tufting is performed at a speed of 800 rpm under the condition of 10 needles per inch in the width direction and 13 needles per inch in the length direction when tufting. After tufting, one adjacent loop to the loop to be measured is cut off and a loop with 10 loops apart on the opposite side is cut off. An average of 10 intensity peaks appearing when the loops to be measured are pulled in a direction perpendicular to that of the non-woven fabric using an Instron is calculated. The number of specimens is three.
  • the non-woven fabric according to the present invention is improved in formability and pullout strength in the process of preparing a carpet, thereby contributing the improvement of productivity and quality of the carpet.
