Description
PROCESS FOR TREATING FIBERS WITH AN ANTISTATIC FINISH Description
This invention relates to a process for applying an antistatic finish to fibers, especially to nylon carpet fibers. The use of mono - and di - alkyl phosphate salts as components of antistatic finishes for nylon fibers is known to the art.
In DE 2528258 compositions having antistatic and soil releasing properties are disclosed that contain a fluoroalkyl polymer and an alkyl phosphate salt of the formula
(RO)bPO(OM)3.b in which R = C6.20 alkyl, M = an alkali metal ion, and b = 1 or 2. JP79,107,885 discloses phosphate alkyl ester salts, the alkyl groups of which contain from 1 to 22 carbon atoms, optionally containing ethylene oxide units, as antistatic agents for nylon fibers.
Netherlands application No. 7505229 discloses compositions containing a fluoroalkyl substituted polymer, a nonionic or anionic surfactant, a polyalkylene glycol alkyl ether, a polyvalent metal salt and/or a copolymer of styrene and an acrylate, and a phosphate alkyl ester salt having the formula (R0)bP0(0M)3.b in which R is a C6.20 aliphatic residue, M is an alkali metal, and b = 1 - 4.
In prior art compositions and processes, including those disclosed above, in which the compositions contain a mono- or di- alkyl phosphate salt, the compositions are applied to nylon fibers at relatively low temperatures.
It has now been discovered that when certain mono- and/or di- alkyl phosphate salts are present in antistatic compositions for application to synthetic fibers such as
nylon fibers, the synthetic fibers can be subjected to an autoclave step, which step results in highly enhanced antistatic properties without resulting in appreciable decomposition of the applied antistatic composition. Moreover, the autoclaved fibers exhibit a much higher retention of the antistatic composition during subsequent processing steps such as carding, drafting and spinning.
This resistance to autoclaving is quite surprising. No current process for applying an antistatic finish to synthetic fibers such as nylon includes an autoclave step, and antistatic compositions for which autoclaving of fibers treated with them have been tried have decomposed during the autoclave step, i.e. the resulting fibers no longer possessed acceptable antistatic properties. The present process comprises the steps of
A) applying to the synthetic fibers to be treated a composition containing at least one salt of a phosphate partial ester having one or two straight chain C12 alkyl groups, at least one lubricant, and at least one anionic and/or cationic emulsifier, and
B) autoclaving the treated fibers from step A at a temperature in the range of from 93" to 150*C.
The composition used in step A of the above process preferably contains from 12 to 40%, preferably from 15 to 37% by weight of the salt of the phosphate partial ester, from 20 to 50%, preferably from 28 to 42% by weight of lubricant, from 10 to 50%, preferably from 25 to 40% by weight of emulsifier, and from 0 to 25% water.
The above percentages by weight are based on the total weight of the composition.
In addition to the above components, small quantities, e.g. from 0.1 to 10% by weight, of one or more additives can also be present, such as antioxidants, biocides, silicone compounds, fluorocarbon wetting agents.
etc.
In the above composition, the salt of the phosphate partial ester is one or more esters having the formula R(OCH2)nO. O
P -(O-lT), (I)
(R(OCH2)ffl0)
wherein
R is a straight chain C12 alkyl group, i.e. the dodecyl group,
M* is an alkali metal cation, a mono-, di-, or tri- alkyl amine cation, or a mono-, di- or tri-alkanolamine cation, n and m are each independently an integer of from 0 to 6, x is 0 or 1, and y is 2 when x is 0 and 1 when x is 1.
Particularly preferred esters are those wherein n is 0 and x is 0; wherein x is 1 and m and n are both 0; and wherein x is 0 and n is 1 - 6. The lubricant or lubricants in the above composition can be selected from a wide variety of heat-stable natural and synthetic oils. For example, paraffin fractions liquid at room temperature such as white oil; animal oils and animal oil derivatives such as glycerol trioleate and hydrogenated tallow glycerides; vegetable oils such as coconut oil, hydrogenated castor oil, and other hydrogenated or partially hydrogenated oils; and other lubricating oils such as tributyl citrate and tridecyl stearate. The choice of lubricant is not critical to the invention, and many other lubricants can be employed in the above composition, provided they are relatively stable under autoclave conditions.
The anionic and/or cationic emulsifiers that can be employed in the above composition can be any anionic or cationic emulsifier that does not significantly decompose under autoclave conditions. Examples of such emulsifiers include relatively long chain alkyl sulfates, sulfo- succinates, and sulfonates. By relatively long chain is
meant from 6 to 18 carbon atoms in the alkyl groups. Also included are various polyoxyethylene and/or polyoxy- propylene fatty amines, fatty alcohols, fatty acids, and hydrogenated vegetable oils, such as polyoxyethylene tallow amine, polyoxyethylene hydrogenated castor oil, polyoxy¬ ethylene coconut fatty acid. The above polyoxyalkylene compounds can contain from 2 to 25 ethyleneoxy and/or propyleneoxy groups. Here again, the particular anionic or cationic emulsifiers or mixtures of emulsifier or mixture of emulsifiers selected for use in the above composition is not critical to the invention.
The synthetic fibers that can be treated by the present process include nylon fibers, i.e. where the fiber forming substance is any long chain synthetic polyamide having recurring amide groups (-CONH-) as an integral part of the polymer chain. Examples include but are not limited to nylon 66, nylon 4, nylon 6, nylon 9, nylon 11, and nylon 610. In addition, synthetic polyester fibers can be treated with an antistatic finish by the present process. The present process is particularly useful in applying an antistatic coating to carpets, especially nylon carpets.
The synthetic fibers are treated with the antistatic composition at room temperature, e.g. by spraying or brushing the composition onto the fibers. Generally, from 1.0 to 1.8% by weight, preferably from 1.0 to 1.5% by weight of the composition, based on the weight of the fibers, is applied to the fibers.
The autoclave step is carried out at a temperature in the range of 93" to 150'C, preferably in the range of llθβ to 143*C, and more preferably in the range of 135" to 141*C, for a period of from 30 minutes to 90 minutes, preferably from 45 minutes to 75 minutes. An autoclave temperature of 138*C for 60 minutes has proven particularly useful. The synthetic fibers treated by the process of the invention exhibit excellent antistatic properties and the antistatic coating has proven to be unusually durable and
long lasting, even after repeated cleaning of the fibers.
The invention will be illustrated but not limited by the following examples.
EXAMPLES EXAMPLE 1-3
The antistatic finish formulations set forth in Table I were prepared by mixing together the specified ingred¬ ients in the percent quantities shown.
The formulations were applied to nylon fibers in the quantities given in Table I.
Static half life results are set forth both before and after autoclaving in Table II.
Autoclaving was carried out by heating the treated nylon fibers to a temperature of 113βC for from 3-4 min¬ utes, venting and exhausting the autoclave, heating the fibers to 138°C for 4 minutes followed by venting and exhausting, heating the fibers for 4 minutes at 138*C followed by venting and exhausting, and finally heating the fibers to 138'C for 8-12 minutes also followed by venting and exhausting.
The static half life measurements were made by first cutting 25.4 by 63.5 mm test sections of cloth made from the nylon fibers. These test sections were washed in 50/50 by volume isopropyl alcohol/water, rinsed in water, air dried, and each antistatic finish formulation in the form of 1% aqueous emulsion was applied to 8-10 test sections. The resulting test sections were then air dried. Autoclaving was carried out as above for half of the test sections. Antistatic testing was carried out in a Rothschild Static Voltmeter R-3021, manufactured by Rothschild Messinstrumente 8002 Zurich, Switzerland, Traubenstrasse 3, using an applied voltage of 100 volts. The static half life is the time in which the voltage dropped to 50 volts. The test was carried out using 4-5 identical test sections and the results were averaged.
Comparison Examples 1-14
The comparison formulations set forth in Table I were prepared and tested in the same manner as Examples 1-3, and the static half life results are given in Table II. As can be seen from Table II, the formulations of the invention (Examples 1-3) produced excellent and consistent antistatic properties on nylon fibers, even after auto¬ claving, while the formulations of the comparison examples (Comparison Examples 1-14) showed either much poorer or inconsistent antistatic properties after autoclaving.
Note: POE followed by a number in parenthesis means the number of oxyβthylene groups In the molecule.
All esters are mixtures of compounds of formula I wherein x ■ 0 and x = 1 in a mol ratio of from 50:50 to 65:35.
