Description

Composition for Producing Polyester and Polyamide Yarns With Improved Moisture Management Properties
The present application is related to and claims the priority of Provisional
Application Serial Number 60/713,758, filed September 6, 2005.
BACKGROUND AND FIELD OF THE INVENTION
This invention relates generally to a composition and process for preparing articles having improved moisture management properties.
More particularly, the invention relates to a composition and process for
preparing polyester-based fibers and polyamide-based fibers that exhibit improved moisture management or wicking properties without detrimental
loss of other desirable physical properties. The fibers of the invention may
be used in both textile and floor covering applications. Synthetic fibers have generally suffered from an inability to wick moisture efficiently. Improvements in the wicking properties of fibers are highly
desirable in many applications. For example, in a textile application such
as an article of apparel, including an efficient wicking fiber may provide
the wearer with greater perceived comfort. In a floor covering application, improved wicking properties may assist in drying of the floor covering after shampooing and cleaning. In addition, improved wicking assists in
the transport of accidental water-based unsightly stains away from the face of the floor covering to the backing, thus hiding the stain from view. We have invented a new composition which is very effective and economical in providing moisture wicking polyester fibers and polyamide fibers used in making textiles and floor coverings. SUMMARY OF THE INVENTION
According to our invention, a composition for preparing polyester-based
yarns or polyamide-based yarns having improved moisture management
properties includes a polyester or polyamide, and one or more polyoxyalkyleneamines. Preferably, the composition contains from about
97 to about 99.75 % by weight of polyester or polyamide and from about
0.25% to about 3 % by weight of polyoxyalkyleneamine. Most preferably,
the composition contains from about 98 to about 99.5 % by weight of
polyester or polyamide and from about 0.5% to 2 % by weight of polyoxyalkyleneamine.
The polyoxyalkyleneamine may be added directly to the polyester or polyamide, or in the form of a thermoplastic concentrate or masterbatch by compounding it in a suitable thermoplastic carrier. Suitable thermoplastic carriers are polyester or polyamide or mixtures thereof. The
polyamide includes those synthesized from lactams, alpha-omega amino acids, and pairs of diacids and diamines. Such polyamides include, but
are not limited to, polycaprolactam [polyamide 6], polyundecanolactam [polyamide 11], polyhexamethylene adipamide [polyamide 66],
polylauryllactam [polyamide 12], poly(hexamethylene dodecanediamide
[polyamide 6,12], poly(hexamethylene sebacamide) [polyamide 6,10], poly(ethylene terephthalate), poly(butylene terephthalate), poly(trimethylene terephthalate). If the polyoxyalklenediamine is used in this masterbatch form, then the amount of polyester or polyamide in the above formulation is adjusted to take into account the amount of the thermoplastic carrier in the polyoxyalkylenediamine masterbatch.
The preferred polyoxyalkyleneamine is poly(oxyethylene)diamine (POED)
with a molecular weight of about 2000. Another preferred
polyoxyalkyleneamine that can be used in the invention is poly(oxypropylene)diamine, also with a molecular weight of 2000. These
compounds are available from Huntsman Corporation under the
Jeffamine® trademark. Further details of suitable polyoxyalkylened-
iamines are described in U.S. Patent No. 3,654,370. Polyesters include thermoplastic polyesters such as those synthesized from one or more diacids and one or more glycols. Such polyesters
include, but are not limited to, poly(ethylene terephthalate, poly(butylene
terephthalate), poly(propylene terephthalate), poly(ethylene naphthalate), poly(propylene naphthalate), poly(butylene naphthalate), poly(cyclohexane dimethanol terephthalate) and poly(lactic acid), or
mixtures thereof.
Polyamides include thermoplastic polyamides such as those synthesized
from lactams, alpha-omega amino acids, and pairs of diacids and diamines. Such polyamides include, but are not limited to, polycaprolactam [polyamide 6], polyundecanolactam [polyamide 11],
polyhexamethylene adipamide [polyamide 66], polylauryllactam [polyamide 12], poly(hexamethylene dodecanediamide [polyamide 6,12], and poly(hexamethylene sebacamide) [polyamide 6,10]. Besides the polyester or polyamide, and polyoxyalkyleneamines described
above, the compositions used in the practice of the invention may contain
other components. These include, but are not limited to, colorants,
antioxidants, UV stabilizers, antiozonants, soilproofing agents,
stainproofing agents, antistatic additives, flame retardants, antimicrobial
agents, lubricants, melt viscosity and melt strength enhancers, chain
extenders, coupling agents, solid-state polymerization accelerators and
processing aids.
Fibers produced from the composition can be melt-spun using various
methods to create different products for a multitude of end use
applications. The fibers can be spun using standard spinning machinery
known to those skilled in the art including both slow speed and high speed
spinning processes. A range of denier per filament (dpf) may be
produced depending on the ultimate end use to which such fibers may be
put, for example low dpf for textile use and higher dpf for use in carpets.
The cross-sectional shape of the fibers may also be any of a wide range of
possible shapes, including round, delta, trilobal, tetralobal, grooved or
irregular.
These product fibers may be subjected to any of the known downstream
processes normally carried out on melt-spun fibers, including crimping,
bulking, twisting, etc., to produce yarns suitable for incorporation into a
variety of articles of manufacture, such as apparel, threads, textiles,
upholstery fabrics, carpets and other floorcoverings. The fibers may be
blended, entangled, twisted or other mixed with other fiber types including, but not limited to, synthetic fibers such as polyesters,
polyolefins or acrylics, or natural fibers such as wool or cotton, and
mixtures thereof.
EXAMPLES OF THE INVENTION
These examples are provided to illustrate the invention but are not
intended to limit the scope of the invention in any way.
Example 1
15 % by weight of POED was compounded with PET, IV=O.67, in a vented
twin-screw extruder, stranded, pelletized and dried. The POED
masterbatch was further compounded in a vented twin-screw extruder at
the 10% level with PET, IV=O.67 and a black color concentrate. The
resulting compound was dried and spun on a melt-extruder fiber spinning
line at 3100 m/minute and false-twist textured to give a 150 denier yarn
consisting 34 filaments of a round cross-section (150/34R).
Example 2
A comparative (non-inventive) 150/34R yarn was spun and false-twist
textured in a similar manner to Example 1, except the POED masterbatch
was omitted.
Example 3
15 % by weight of POED was compounded with nylon 6, RV=3.3, in a
vented twin-screw extruder, stranded, pelletized and dried. The POED
masterbatch was further compounded in a vented twin-screw extruder at
the 10% level with PET, IV=O.67 dig'1, and a black color concentrate. The
resulting compound was dried and spun on a melt-extruder fiber spinning line at 3100 m/minute and false-twist textured to give a 150 denier yarn
consisting 34 filaments of a round cross-section (150/34R).
The yarns produced in Examples 1 - 3 were circular knitted into socks of
about 3 - 4 oz/yd2. The water transport rate was determined as follows:
The water transport rate is measured according to a so-called vertical
strip wicking test. One end of a sock (approx. 4 inches wide x 12 inches
long) was clamped vertically with the dangling end immersed to about 1A
inch in distilled water at 210C. The time taken for the water to be
transported along the strip every inch (distance traveled) was measured.
Shorter times per distance traveled indicate greater liquid water transport
ability.
Table 1 shows the test results for Examples 1 to 3 for the vertical strip
wicking test. These results are shown graphically in Figure 1. The results
for both the inventive Examples 1 and 3 show a dramatic improvement in
water transport rate over the non-inventive Example 2.
Table 1
3 Distance Traveled/ inches
Example 4
15 % by weight of POED was compounded with PET, IV= 0.67 dig"1, in a
vented twin-screw extruder, stranded; pelletized and dried. The POED
masterbatch was further compounded in a vented twin-screw extruder
with Irgamod RA20, a chain extender available from Ciba Specialty
Chemicals, Inc., in the ratio of 10 parts of the POED masterbatch to 2
parts of Irgamod RA20. The resulting material was then melt compounded
with a nylon 6,6 resin, RV = 3.1. This compound was dried and spun on a
melt-extruder fiber spinning line to give a 1850/30Y undrawn yarn. Two
undrawn yarns bundles were draw-textured and entangled together to
give a 1200/60Y BCF yarn. Example 5
A comparative (non-inventive) nylon 6,6 1200/60Y BCF yarn was
produced without the addition of the POED masterbatch or the Irgamod
RA20.
Example 6
15% by weight of POED was compounded with nylon 6, RV=3.3, in a
vented twin-screw extruder. The POED masterbatch produced was
letdown into nylon 6,6, RV = 3.1 directly on a fiber-spinning extruder,
then two yarn ends were draw-textured and entangled to give a 1200/60Y
BCF yarn.
The yarns produced in Examples 4 - 6 were knitted into socks of similar
construction on a circular knitter. The water transport rate was
determined for each sock in a similar manner to that described above.
The results are given in table 2 and shown graphically in figure 2.
Inventive examples 4 and 6 showed significantly higher water wicking
rate over the non-inventive example 5.
