Definitions
- the present invention relates generally to textiles, spinning, twisting, and twining. More particularly, the invention relates to a crimped or textured, continuous nylon-6 filament.
- a bulky product will have to be made of a bulky fiber or filament, as the basic constructional element of any textile product is the fiber or filament.
- the present invention is an improved crimped, continuous nylon-6 filament.
- the crimped nylon-6 continuous filament of the present invention shows a complete absence of a spherulitic ring structure when the cross section thereof is viewed under polarized light.
- the result of the absence of such a spherulitic ring structure is that the filament is more lustrous than available prior art filaments under otherwise identical conditions.
- the fiber producer may increase bulk and cover in a fibrous structure such as a carpet without any loss in luster.
- a crimped nylon-6 continuous filament characterized by the absence of a spherulitic ring structure along the periphery of the cross section thereof when the cross section is viewed under polarized light.
- Fig. 1 depicts an available crimped nylon-6 continuous filament (1) of the prior art, which is shown in two cross sections thereof as viewed under a microscope under polarized light.
- a characteristic spherulitic ring (2) is observed along the periphery of the cross sections.
- small particles (4) of a delustrant such as titanium dioxide.
- the spherulitic ring (2) is comprised of a multiplicity of individual partial spherulites (3), which, although not visible under ordinary conditions, are visible under polarized light.
- the filaments depicted here have a modification ratio of between about 2 and 3, i.e., the configuration thereof is commonly referred to as "trilobal".
- the presence or absence of any peripheral ring is determined by visual observation of the section, under polarized lighting (phase-contrast or dark field may also be employed); a photomicrograph can also be obtained under these conditions.
- Fig. 2 Depicted in Fig. 2 is one embodiment (5) of the crimped nylon-6 continuous filament according to ' the present invention, which is shown in two cross sections thereof as viewed under a microscope under polarized light. No spherulitic ring is observed along the periphery of the cross sections, as at (6). Seen in the cross sections are small particles (4) of a delustrant such as titanium dioxide.
- the filaments depicted here also have a modification ratio as discussed above of between about 2 and 3, i.e., the configuration thereof is commonly referred to as "trilobal".
- filaments according to the present invention may have other cross sectional configurations as well, under which conditions the same advantages and benefits over the prior art are observed.
- filaments of the present invention have a higher luster-as determined visually or by any of many standard optical methods known to the skilled artisan-when compared with otherwise equivalent filaments of the prior art which have the same level of crimp, or the same level of delustrant in an amount which is substantially below the saturation level thereof, or the same cross sectional configuration.
- filaments according to the present invention which are substantially free of any delustrant are considered to be very highly lustrous. If not as much luster is desired, one of the delustrants known to those of skill in the art may be employed. These include not only the usual non-chromatic delustrant and fillers such as titanium dioxide, zinc sulfide, calcium carbonate, glass particles, etc., but also delustering agents which impart color as well. Such include organic and inorganic pigments and dyes that are added to the molten nylon-6 polymer prior to or during extrusion and spinning, or to the nylon-6 polymer in chip form in a dyeing operation prior to extrusion and spinning. When titanium dioxide is employed, it is advantageously present in an amount of not greater than about 0.1 percent by weight.
- the crimped nylon-6 continuous filament of the present invention advantageously has a tank bulk of at least 8 percent and a denier of at least 5. Under these conditions it is especially suitable for use in the fabrication of a large number of textile structures desirable in today's market.
- Tank bulk is determined by first measuring the length change in a skein of fiber exposed to boiling water under two loads of approximately 0.0003 g/dtex (L 2 ) and 0.09 g/dtex (L,), respectively. Tank bulk is then calculated employing the following equation:
- the crimped nylon-6 continuous filament according to the present invention has a modification ratio of between about 2 and 3 and a denier of between about 5 and 25. Under these conditions, use of the filament according to the present invention results in carpets having outstanding characteristics.
- a crimped nylon-6 continuous filament according to the present invention which has a denier of at least 5 is found to have another significant morphological characteristic, viz: the ratio of y-form nylon-6 to a-form nylon-6, is at least 1 to 1, and often about 3/1 to 3.5/1, as measured on non-heat treated, undeyed, crimped filamentary material. This compares with y-form to a-form ratios of about 1/3 to 1/3.5 for available prior art products under the same conditions of treatment. However, after heat setting of the crimped filamentary material of the present invention, the a-form is predominant.
- Such products according to the present invention which have a ratio of y-form nylon-6 to a-form nylon-6 are especially desirable when substantially free of any delustrant, or when a delustrant such as titanium dioxide is present therein in an amount not greater than about 0.1 percent by weight.
- modification ratios of between about 2 and 3 are highly advantageous,-as is a tank bulk as specified supra of at least about 8 percent.
- any of the filaments according to the present invention may be employed in a multifilament yarn-e.g., grouped together with other filaments according to the present invention-which may be interlaced and/or twisted, utilizing standard techniques well-known to those of skill in the art, to produce carpets, upholstery, and other such textile structures having outstanding characteristics.
- Nylori-6 chips having a relative viscosity of 2.69 as measured in 96-98% sulfuric acid and containing less than 0.01% titanium dioxide were melted in an extruder and spun at a temperature of 265° through two spinnerettes with 99 irregular shaped holes each at a thruput of 335 grams per minute per spinnerette forming two 99 filament threadlines.
- the spun filaments were quenched * with a crossflow of air at approximately 12°C, and were lubricated with an oil spin finish comprising a polyalkoxylated alcohol containing essentially no water.
- the fiber was stretch pre-tensioned 1 1/1 %, pre-heated to 45°C, and stretched 3.25x to a speed of 2119 meters per minute and heated to 165°C.
- the stretched threadlines were crimped in a hot air texturizer such as that in US Patent 3,908,248, and deposited onto a rotating cooling sieve through which air was moved by means of a vacuum.
- the sieve moved at a velocity of 45 meters per minute.
- the threadlines were unraveled from their plug form on the cooling sieve to a speed of 1732 meters per minute established by a cold pair of godets.
- the yarns were subsequently interlaced in a conventional air jet and wound up under 200 pond tension on a double cup winder. There was no spherulitic ring structure along the periphery of the cross section of the fiber when viewed under a microscope under polarized light.
