JP 2001-226843 A JP 2002-88663
  The object of the present invention is to solve the problems in the prior art as described above, and is a fiber product made of polypropylene fibers that can be dyed in multiple colors by dyeing in post-processing and has excellent spinning stability. Is to provide.
This invention exists in the polychromatic fiber product which consists of disperse dye dyeable fiber and disperse dye non-dyeing fiber which satisfy | fills following (1) and (2).
(1) The disperse dyeable fiber is partially dyed with two or more different colors in the length direction of the yarn, and the dyeing length of the same color is 1 to 3 on the surface of the polychromatic fiber product. 50 cm.
(2) The mixing ratio of the disperse dyeable fiber is 3 to 50% by mass.
Furthermore, the present invention is characterized in that the polychromatic fiber product is a carpet.
  A fiber product comprising a disperse dye-dyeable polypropylene fiber dyed by the disperse dye of the present invention and a disperse dye non-dye fiber has a high nap and a bulky feeling, and has a suitable texture, and further has a mixed texture. By weaving, it becomes a high-quality polychromatic fiber product. As a patterning method using mixed weaving, dyeing of dyeable polypropylene fibers that are dyed with disperse dyes in the tufting process of disperse dye-non-dyed fibers (cheese dyeing, casserole dyeing, roller printing, space printing) Die etc.) Fibers with excellent design and high quality can be obtained by drawing a pattern by combining the fibers. Further, if post-dyeing (raw machine dyeing, screen printing, transfer printing, paper-type printing, etc.), a high-quality multicolored fiber product can be obtained. In the present invention, examples of the disperse dye-immiscible fibers include original polypropylene fibers and nylon fibers.
  The textile product capable of multicolor dyeing according to the present invention has a soft texture and is excellent in nap, bulkiness, design, and multicolor, so it is suitable for use in vehicle option mats, rugs and piece carpets. Is possible.
Hereinafter, the present invention will be described in detail.
The disperse dyeable dyeable polypropylene fibers used in the present invention are pre-dyed (cheese dye, casserole dye, roller printing, space dye, etc.) fibers on the surface of the polychromatic fiber product (hereinafter referred to as the same dyeing area). , The same staining length) is required to be 1 to 50 cm. More preferably, the same staining length is 2 to 15 cm. When the same dyeing length is less than 1 cm, even if space dye dyeing is performed, the dyed yarn does not exhibit the characteristics, and the fiber product has a poor feeling of contrast (contrast). Moreover, when it exceeds 50 cm, even if the pre-dyed fiber is multicolored, the color switching frequency is lowered, which is not preferable.
Further, the mixing ratio of the disperse dyeable polypropylene fiber is required to be 3 to 50% by mass. The mixing ratio of the disperse dye-dyeable polypropylene fiber is more preferably 5 to 25% by mass. If the mixing ratio of the disperse dye-dyeable polypropylene fiber is less than 3% by mass, the feeling of contrast (contrast) is poor and the design is poor. On the other hand, if the mixing ratio exceeds 50% by mass, the design is poor and the design is lowered.
Thus, in the present invention, if a pattern is drawn with a fiber that is not dyed by a disperse dye in a tufting process and a disperse dye-dyeable polypropylene fiber, a polychromatic fiber product that is excellent in design and high-quality can be obtained. A typical example of the polychromatic fiber product of the present invention is a carpet. The carpet may be a cut pile carpet, a cut pile carpet in which a part of the cut pile is mixed, or a cut and loop pile carpet in which a part of the loop pile is mixed.
  The disperse dye dyeable fiber used in the present invention is preferably a disperse dye dyeable polypropylene fiber. Dispersible dye-dyeable polypropylene fibers can be crimped to be crimped fibers, and the dyeable polypropylene-based crimped fibers obtained after crimping are twisted. May be. In addition, additives such as coloring pigments, dispersants, fluorescent brighteners, matting agents, lubricants, antistatic agents, deodorants, antibacterial agents, flame retardants, etc., are included within the range that does not impair the high elongation properties of the fiber. The types and amounts of these additives may be different.
  On the other hand, as the disperse dye non-dyeing fiber used in the present invention, a polypropylene fiber is preferable. In general, disperse dye-dyeless fibers include polypropylene fibers and nylon fibers, but polypropylene fibers are attracting attention as environmentally friendly resins from the standpoint of containing no harmful substances and being easy to recycle. In addition, polypropylene fibers are more preferable from the viewpoint of reducing environmental burden. Polypropylene fibers that are not dyed by disperse dyes can be crimped to be crimped fibers, and, after crimping, twist the obtained dyeable polypropylene-based crimped fibers. You may spend it. Additives such as color pigments, dispersants, fluorescent brighteners, matting agents, lubricants, antistatic agents, deodorants, antibacterial agents, flame retardants, etc. are included within the range that does not impair the high elongation properties of fibers. The types and amounts of these additives may be different.
  The disperse dye-dyeable polypropylene fiber constituting a part of the present invention preferably contains 5 to 15% by mass of a polybutylene terephthalate resin. The polybutylene terephthalate resin contained in the disperse dye dyeable polypropylene fiber is a disperse dye dyeable component. The mixing ratio of the polybutylene terephthalate resin is required to be 5 to 15% by mass, and preferably 5 to 10% by mass. If it is less than 5% by mass, desirable dyeability cannot be obtained, and if it exceeds 15% by mass, the spinning stability of the disperse dye-dyeable polypropylene fiber may be lowered.
  Further, the melting point of the polybutylene terephthalate resin contained in the disperse dyeable polypropylene fiber is preferably 30 ° C. or less, more preferably 15 ° C. or less, with respect to the melting point of the polypropylene resin. When the melting point difference exceeds 30 ° C., the polybutylene terephthalate resin does not melt sufficiently at the temperature at which the polypropylene fiber is melt-spun, and remains as a solid foreign substance in the melted polypropylene-based resin. There is a risk of lowering the spinning stability. Further, at the temperature at which the polybutylene terephthalate resin is melt-spun, the melt viscosity of the polypropylene-based resin is lowered, and the spinning stability may be lowered.
  In the present invention, the crimp ratio of the disperse dye-dyeable polypropylene fiber constituting a part of the polychromatic fiber product is preferably 5 to 20%, more preferably 10% or more. When it is 10% or more, it is possible to obtain a fiber product (carpet) having a higher nap feeling while being bulky. If the crimp rate is less than 5%, the bulkiness and the feeling of napping become inferior.
  Furthermore, the cross-sectional shape of the disperse dye-dyeable polypropylene fiber constituting a part of the pleochroic fiber product of the present invention is circular, triangular, flat, hollow, multi-core hollow cross-section, Y-shaped cross-section or cross-shaped cross-section. Any of multileaf type cross sections having 3 to 6 leaves (ribs) may be used. In particular, it is more preferable that the dyeable polypropylene fiber has a multi-leaf type cross section in which high bulkiness can be easily obtained, because a bulky carpet is obtained.
Next, an example of the manufacturing method of the polychromatic fiber product of this invention is demonstrated.
The disperse dye-dyeable polypropylene fiber constituting a part of the pleochroic fiber product of the present invention can be obtained by a known melt spinning method for polypropylene fibers. In melt spinning, disperse dye-dyeable polypropylene fibers are composite fibers such as a core-sheath structure or a laminated structure, as long as a thermoplastic resin composition such as polybutylene terephthalate is disposed at least on the fiber surface. There may be a composite spinning in the melt spinning.
Next, the resin melted by the melt extruder is extruded from a spinning nozzle, a spinning oil is applied to the surface of the spun yarn, and the yarn is wound to obtain an undrawn yarn. The unstretched yarn may be continuously stretched in a continuous process, or may be stretched after being wound once. Stretching may be performed in one or more stages, and the setting of the stretch ratio in the multistage stretching is not particularly limited.
  Furthermore, it is also possible to give a crimp by performing a hot air crimping process. At this time, without winding the melt-spun undrawn yarn, it is continuously drawn simultaneously with hot-air crimping, directly spun-drawn crimped with air entanglement, or once undrawn yarn is wound up and then drawn simultaneously. Hot air crimping, air entanglement, or the like can be used.
  In the stretching process, the heat source may be a contact type or a non-contact type. The draw ratio is preferably 2 to 7 times. If the draw ratio is less than 2 times, the fiber strength of the obtained filament yarn becomes low, and if it exceeds 7 times, the risk of occurrence of yarn breakage or the like increases. The stretching temperature is preferably in the range of 50 to 130 ° C. If the stretching temperature is less than 50 ° C., the draw ratio cannot be increased, and as a result, the fiber strength of the filament yarn obtained becomes low, while 130 If it exceeds ℃, thread breakage occurs.
Subsequently, in the method for producing a polychromatic fiber product, a crimped yarn of disperse dye-dyeable polypropylene fiber can be obtained in advance by a known dyeing method. For example, if the dyed yarn obtained by multi-color space dye dyeing and a crimped yarn that is not dyed by disperse dyeing are partially arranged and tufted, the design property can be improved. A highly pleochroic textile product is obtained. The arrangement method can be arbitrarily selected.
It is also possible to post-dye the pleochroic fiber product (raw dyeing, screen printing, transfer printing, paper type printing, etc.). Furthermore, if a fiber product mixed with fibers dyed with other dyes is dyed in multiple colors, a fiber product having a multicolor feeling can be obtained.
Next, the resulting multicolored textile product with high designability is a cut pile carpet, a cut pile carpet in which a cut pile portion is mixed in part, or a cut and loop pile carpet in which a loop pile portion is mixed in part. Also good.
After forming the carpet of the textile product, an adhesive is applied to the back surface, and the adhesive is dried and cured to fix the pile, thereby obtaining a carpet made of the dyeable polypropylene fiber of the present invention. At this time, a lining according to the application, for example, a sheet made of synthetic rubber or vinyl chloride resin or linen may be attached to the back surface of the base material via the adhesive. As the adhesive to be used, any adhesive can be used depending on the use and the material of the backing. For example, it can be appropriately selected according to the type of the base fabric such as acrylic latex or urethane adhesive.
In addition, about the evaluation method of a textile product, it carried out as follows.
