Definitions

  • This invention relates to fabrics, and yarn from which they may be formed, on to which material has been reacted so as to give permanently improved performance properties to the fabrics.
  • the invention is of particular applicability to the production of fabric for clothing which will give a cooling effect to the wearer when exposed to warm or hot ambient conditions.
  • the invention can also be applied to improvement in soil release and crease resistance and abrasion properties of fabric.
  • the Bruno and Vigo fabrics are based on cotton and cotton polyester blends and in the examples are made by impregnating with a bath of 50% (500g/l) polyethylene glycol 1000, 11% dimethylol dihydroxy ethylene urea, 3.3% magnesium chloride, and 1% citric acid to a wet pickup of about 100% followed by drying at 70 °C and then curing for two minutes, followed by washing.
  • the data demonstrates dry add-on values generally ranging from 21.6 to 52.8%. These high add-ons will, in addition to giving heat retention, also tend to affect significantly the handle of the fabrics.
  • the dry add-on is said to be 10.6%.
  • This process is conducted with curing at 100°C. We show below that curing for 2 minutes at 100°C does not cause significant bonding onto the fabric. It is therefore clear that this 10.6% is merely the amount which was not washed off by the first wash and that it is not permanently bonded to the fabric and most or all of it will be washed off by subsequent washes. Accordingly it is irrelevant to the production of commercially useful fabrics since these must have permanent properties. It is essential with such fabrics that substantially all the add-on on the fabric when received by the customer should remain permanently bonded despite repeated washings.
  • One object of the invention is to provide a fabric having permanent properties such that the fabric, when worn in warm or hot weather, will give the wearer a cooling sensation. Another object is to modify permanently the properties of cotton and other non-linen fibres so that they approach or exceed the desirable properties (especially as regards the cooling effect and rate of water absorption) of linen. Another object is to provide a fabric which can react strongly with isocyanate-based adhesives so as to form a polyurethane adhesive layer firmly secured to the fabric. Another object is to provide a cotton or other fabric which has improved non-iron and comfort properties. Another object is to provide a fabric having permanently improved soil release and/or crease resistance and/or abrasion resistance. Other objects are to provide yarns which can be woven or knitted to form such fabrics.
  • a fibrous product which is selected from fabrics and yarns and which comprise fibres of cellulose, wool or polyamide and which includes polyethylene glycol substantially uniformly distributed through the product and in which the polyethylene glycol is present in an amount of 0.5 to 8%
  • substantially all the polyethylene glycol is substantially permanently bonded to the fibres of the product.
  • the product usually contains textile cross linking agent as well as the PEG, and the total add-on of these two materials is usually in the range 1 to 15%, preferably 1 to 12%, by weight. Generally the total add-on onto the fabric is within this range.
  • the low add-on of polyethylene glycol (and usually crosslinking agent) which is required in the invention is best achieved by applying to the yarn or fabric a dilute aqueous composition of the polyethylene glycol and crosslinking agent and optionally washing the yarn or fabric. By applying this dilute solution and curing it, the desired low add-on values are achieved.
  • the process can be conducted on yarn, but preferably the process is conducted on fabric.
  • a process of the invention comprises impregnating the fabric, or the yarn from which it is formed, with an aqueous composition having a total solids content of below 300 g/1 and which contains a textile crosslinking agent and 10 to 150 g/1 polyethylene glycol, drying the fabric or yarn and curing the product, and optionally washing the fabric or yarn, and thereby producing a product wherein substantially all the polyethylene glycol is substantially permanently bonded on to the fibres.
  • the product is made by applying and curing the polyethylene glycol onto the fibres as a dilute solution and optionally washing the fabric.
  • the curing may sometimes be performed in such a way that some (e.g., 0 to 10% or 20%) of the polyethylene glycol remains unreacted.
  • the product is generally given a thorough wash after curing to remove unreacted polyethylene glycol to produce a washed product wherein the polyethylene glycol is permanently bonded to the product and is present in an amount 0.5 to 8%.
  • substantially all the polyethylene glycol is permanently bonded we mean that the amount which can be removed by subsequent washing (after the first wash) is acceptably low.
  • this generally means that at least 80%, and most preferably at least 90%, of the washed add-on of polyethylene glycol will remain on the fabric, or a fabric formed from the yarn, after a further 20 washings at 40°C.
  • the fabric does not significantly change its properties when it is subjected to the normal washing encountered by a clothing fabric.
  • a textile cross linking system is normally utilised to cross link the polyethylene glycol on to appropriate reactive groups of the relevant fibres of the fabric or yarn.
  • These fibres are preferably cellulosic, wool or polyamide fibres.
  • Preferred fibres are cellulosic, and in particular they are preferably cotton or viscose (including modified viscose such as Molinease) , with cotton fibres being particularly preferred.
  • the yarn or fabric can be formed solely from the specified fibres or from other fibres as well, for instance the yarn or fabric can be formed from a blend of cotton and polyester.
  • the amount of cellulosic or other reactive fibres is usually at least 30%, and preferably at least 60%, by weight of the fibres in the fabric.
  • Preferred products of the invention comprises cellulose fibres and the 0.5 to 8% add-on of polyethylene glycol is based on the weight of cellulosic fibres in the product.
  • the preferred cellulosic fibre is cotton.
  • the textile crosslinking agent will be selected having regard to the chemical reactivity of the fibres on to which the polyethylene glycol is to be reacted.
  • the preferred curing agent is a bifunctional or polyfunctional reagent that will react with hydroxy groups in the polyethylene glycol and hydroxy or other reactive groups in the cellulose or other fibres.
  • Typical cross linking agents for this purpose are alcohols, triazones, aldehydes such as glyoxal and methylol urea derivatives that will react with the fibres and polyethylene glycol in preference to undergoing self -polymerisation.
  • the preferred crosslinking agent is preferably a textile crosslinking agent having two or more N-rr.ethylol groups.
  • the crosslinking agent is a dimethylol cyclic alkyle ⁇ e urea derivative.
  • the preferred cross linking agent is dimethylol dihydroxy cyclic methylene or ethylene urea.
  • the total add-on of polyethylene glycol and crosslinking agent on the product is generally in the range 1 to 12%, based on the dry weight of the product.
  • the combined dry weight of the polyethylene glycol and the crosslinking agent preferably provides at least 70%, and usually at least 85% of the total add-on to the fabric or yarn and thus the total add-on is also generally within approximately the range 1 to 12%, or perhaps up to 15%.
  • the advantage of the invention is that the provision of these relatively low add-ons of permanently cured material comprising polyethylene glycol allows for very useful modification of the properties of the cotton or other cellulosic or other fibres but at on add-on value which is sufficiently low that the handle of the product is not deleteriously affected.
  • the fabric, or fabric formed from the treated yarn has a weight which is substantially the same as the untreated fabric and which has a very satisfactory handle and yet can have significantly improved properties.
  • the fabric proposed by Bruno and Vigc had a PEG: crosslinking ratio of approaching 5:1 and was made using a 50% PEG solution. We find that this also contributes to unnecessary weight and adverse handle properties.
  • the ratio is generally not more than 3:1 preferably it is not more than 2:1. It can be low as 0.1:1 but is usually in the range 0.5:1 to 1.5:1, preferably 0.7:1 to 1.3:1.
  • the polyethylene glycol (and crosslinking agent) must be distributed substantially uniformly through the product in order that the product has suitably uniform properties.
  • the product can be yarn, in which event fabric can subsequently knitted or woven from the yarn, but preferably the product is a fabric.
  • the impregnation with the aqueous composition can be by contacting the yarn or, more usually, the fabric with a limited amount of the aqueous composition.
  • the process is conducted by saturating the fabric or yarn with the aqueous composition and then expressing excess aqueous composition out of the product to give the desired add-on.
  • the total dry add-on is below 15%, preferably below 12% and the total polyethylene glycol add-on is generally below 8%.
  • the aqueous composition normally contains at least 30g/l and often 40 or 50g/l polyethylene glycol. However it is undesirable for the amount of PEG to be too high and so it must be below 150g/l, preferably below I20g/1 and most preferably below lOOg/1.
  • the total solids content of the aqueous composition is generally at least 50g/l and usually at least lOOg/1. It is not normally above about 250g/l and best results are generally achieved with concentrations of 100 to 200g/l, for instance up to about 160g/l.
  • the wet add-on (after squeezing but before drying) will be such as to give the desired dry add-on having regard to the concentration of the treatment solution. Since the total dry add-on is normally below 15% preferably below 12% and the total solids content of the treatment solution is generally below 300g/l and most preferably below 200g/l, the wet add-on will usually be below 90%
  • weight of aqueous composition after squeezing based on the dry weight of the impregnated fabric and preferably it will be below 70%.
  • Wet add-on values of 10 ro 20% to 50 or 60% are often preferred.
  • the dry add-on of PEG is usually at least 1%. Good results are obtained in many fabrics with dry add-ons of 1 to 5% PEG, for instance 2 to 4% PEG. However in some products (especially when cooling properties are the primary interest) optimum results are obtained with amounts of PEG above 3%, for instance above 4 or 5%, but usually not more than 7%.
  • the total dry add-on of the composition (consisting essentially of PEG and cross linking agent and optional minor components) is usually in the range 1 to 12%, and is generally above 3% and often above 5%. For instance suitable values are 7 to 10%.
  • Products which are intended to give a cooling effect are usually formed wholly or mainly of cellulosic fibres. They can be of linen or modified viscous but preferably the fibres comprise or consist of cotton.
  • the fabric must be sufficiently permeable that movement of the fabric on the wearer inevitably creates a pumping and/or a venturi effect between the yarns of the fabric thereby causing air to pass through the fabric.
  • the polyethylene glycol on the fabric causes the fabric to absorb moisture rapidly from its surrounding environment.
  • the greatest humidity will, in hot weather, originate from the wearer's side of the fabric due to humidity and moisture being liberated from the skin of the wearer. If the fabric is in contact with the skin, this direct contact will lead to absorption.
  • the fabric is not in tight contact with the skin in which event the skin moisture will increase the humidity of the air between the skin and the fabric and the fabric will absorb this humidity.
  • the preferred fabrics are substantially square woven fabrics since this promotes the pumping or venturi effect.
  • a suitable fabric has 60th/inch in the warp and 60th/inch in the weft and is composed of 2/100' s cotton yarn or 1/50' s cotton yarn.
  • a fabric composed of 80th warp and 64th in the weft will have a more rectangular slot. What is not ideal is to have a warp faced cloth such as a poplin where the warp threads would be approximately 120th/inch and the weft 60th/inch.
  • the number of warp threads is from 50 to 90 (usually 60 to 84) per inch and the number of weft threads is 0.7 to 1.3 times (usually 0.8 to 1.2 times) the number of warp.
  • the warp and weft threads are of the same or similar yarn type.
  • Preferred permeable fabric according to the invention has uniform impregnation with polyethylene glycol and is formed from yarn comprising cotton fibres and has a rate of absorption of water which approximates to or is faster than the rate of absorption of a corresponding fabric wherein the cotton fibres are replaced by linen fibres and the polyethylene glycol impregnation is omitted.
  • the comparative fabric should be made using the same weave and to the same weight and with the same blended fibres, if any are present in the cotton fabric.
  • the rate of absorption can be measured by applying the fabric against a suitable substrate, applying water to one point on the fabric and measuring the rate of wicking of water across the fabric.
  • a particular test is put a fabric composed of 100% polyester on top of a cotton fabric treated according to the invention. Within a period of 60 seconds the drop of water can be seen to change its contact angle from around 60 degrees to less than 30 degrees and the water droplet is pulled through to the base fabric where it spreads very rapidly.
  • the corresponding untreated cotton fabric or the untreated corresponding linen fabric are tested in the same way, the times for the linen fabric are similar but the times for the untreated cotton are much slower.
  • Fabrics according to the invention preferably have a rate which is at least 80%, most preferably at least 90% and usually at least 100%, for instance up to 120 or 150%, of the rate of wicking of the corresponding linen fabric without the PEG impregnant .
  • a permeable fabric is used to give a cooling sensation to a wearer, and the fabric has uniform impregnation with permanently bonded polyethylene glycol and the fabric absorbs moisture from between the skin of the wearer and the fabric and movement of the fabric by the wearer causes air to pass through the fabric and thereby evaporate the absorbed moisture and cool the wearer.
  • the amount of polyethylene glycol should normally be at least 3% in order to obtain a strong cooling effect under appropriate conditions, but lower amounts, e.g., down to 0.5%, are suitable in many products, especially non-iron cotton.
  • the fabric which gives the increase rate of absorption and/or the fabric which gives the cooling sensation should be a fabric according to the invention containing 0.5 to 8% polyethylene glycol substantially all of which is substantially permanently bonded to the fibres of the fabric
  • the invention also includes such fabrics wherein different amounts of polyethylene glycol or other polyhydroxy compound are substantially permanently bonded on to the fabric whereby the specified cooling and absorption properties are obtainable without unacceptably damaging the other properties of the fabric.
  • the amount of aqueous bath impregnated on to the fabric or yarn is generally such as to give a final wet pick-up (after squeezing) of around 30 to 110%, often 70 to 50%, by weight, but final wet pick-ups in the range 20 to 70% are often optimum.
  • the squeezing can be by any conventional way of expressing excess liquid from the fabric, for instance by centrifuging or calendering.
  • the aqueous composition of polyethylene glycol and crosslinking agent will generally include catalysts, and it may include other additives .
  • catalysts are inorganic or organic acids such as citric acid or succinic acid, and/or acidic salts such as magnesium chloride. It is particularly preferred to use a non-phase separating curing agent such as triethylene glycol citrate or other water soluble polyester of citric acid.
  • the amount of the catalyst or catalyst mixture is usually from 2 to 40%, often around 5 to 25%, by weight of the urea or other cross linking agent. Expressed in terms of the concentration of catalyst in the impregnation solution, the amount is usually in the range 2 to 20g/l.
  • the drying is conducted under conventional conditions, such as heating at below 100°C for sufficient time to remove most or all of the water on the fabric.
  • the fabric may be cured immediately or subsequently.
  • the dried fabric may be stored and/or transported (optionally under refrigeration) prior to being made up into clothing and then cured into the made-up configuration.
  • the dried fabric may be made into a shirt and then cured.
  • Curing is effected by heating at an appropriate curing temperature or otherwise activating the cross linking system by irradiation in known manner.
  • the curing is by heating, for instance by hot air while the fabric is stretched on a stenter.
  • the optimum cure temperature is related to the duration of cure in that higher temperatures require shorter cure durations and lower temperatures require longer cure durations.
  • the cure temperature is at least 130°C, preferably 145 to 180°C and most preferably around 155 to 170 °C, since lower temperatures appear to give inadequate permanent cure of the polyethylene glycol on to the fabric.
  • the curing is preferably by flash curing, e.g for a period of 0.1 to 2, usually 0.2 to 1.2 minutes, often about 0.5 to 1 minute.
  • cure temperatures of 100 to 130°C, for instance 110 or 120 to 130°C can be used especially if the curing period is longer, typically up to 3 or 4 minutes.
  • the described temperatures are particularly suitable when the cross linking agent is dimethylol dihydroxy ethylene urea and adjustments in the temperature and time may be required to compensate for more reactive or less reactive cross linking agents.
  • the use of the lower cure temperatures for instance 110 to 140°C and preferably 110 to 130°C are particularly preferred where it is desired to provide a white fabric as it reduces the risk of yellowing.
  • the preferred total add-on's of 5 to 12%, often 7 to 10%, and polyethylene glycol add-on's of 0.5 to 8% by weight are capable of not only giving good cooling properties but may also give other useful benefits such as soil release, increase resistance and/or abrasion resistance.
  • the impregnating solution generally then has a polyethylene glycol concentration of 10 to 50, often 10 to 30 g/1 and a total solids content of below 200 g/1, often below 120 g/1. Usually it is above 20 g/1.
  • the described impregnation and cure gives improved crease resistance as measured by crease recovery angle. It also gives improved wet recovery and thus the fabric is easy to iron or even non-iron.
  • the fabrics also have improved soil release properties. This is particularly surprising since soil release properties are normally achieved by rendering a fabric hydrophobic, but the process of the invention renders the fabric more hydrophillic .
  • Another surprising benefit of the invention is that the treatment increases the affinity of the fabrics to optical whitening agents and the so-called direct dyes and/or reactive dyes. Accordingly it is possible easily to obtain fabrics which not only have the described cool and easy care properties but also improve whitening effect and/or improved dyeing.
  • the optical whitening agent is preferably a fluorescent material and the invention appears to give its desired effect as a result of reducing the tendency for fluorescent quenching to occur. Thus the invention allows maximum fluorescence to be achieved.
  • fabrics having particularly soft hand can be achieved by including a hydroxy-substituted silicone in the aqueous bath.
  • the hydroxy silicone is usually present in an amount of 0.2 to 3%. It is cured into the fabric with the polyethylene glycol and the cross linking system and imparts permanent hydrophilic properties and permanent flexibility to the fabric. It gives enhanced crease resistance and abrasion properties. It is of particular value when the fabric is based on linen since some linen fabrics can have a rather stiff hand.
  • Another way of improving the hand of cotton or other fabrics is to include a small amount of plasticiser with the PEG. For instance partially hydrolysed polyvinyl alcohol (typically 97% hydrolysed) can be used in an amount of 5 to 30g/l.
  • the total add-on of PVA is preferably less than 2% and generally less than 1%.
  • polyvinyl alcohol or other plasticiser preferably the combined amount of PEG and plasticiser is below 8% but in some instances it may go up to 9% or 10% maximum.
  • the amount of polyvinyl alcohol or other plasticiser is above lOg/1, the amount of PEG may be reduced in proportion to it.
  • Various additives may be included in the impregnation solution in order to impart additional desirable properties to the treated fabric.
  • a polymeric biguanide hydrochloride such as the material commercially available from Zeneca under the trade name Reputex. This contributes to providing permanent freshness and elimination or reduction of body odours. Any bacteriastat which is suitable for fabrics and which does not cause yellowing can be used.
  • the permanent bonding of the generally small amount of polyethylene glycol to the fabric can also give advantages in other areas.
  • the resultant fabric has high hydroxyl reactivity to materials that will react with hydroxyl groups, especially isocyanates. Accordingly an isocyanate-based polymer can be securely bonded to the fabric as a result of the formation of urethane linkages due to reaction between the hydroxyl groups of the fabric and the isocyanate groups of the resultant polyurethane .
  • interlining fabrics by applying a heat and pressure-sensitive urethane adhesive to the interlining fabric, whereupon this interlining fabric can be heat cured on to an outer fabric by ironing.
  • this interlining fabric can be heat cured on to an outer fabric by ironing.
  • it is particularly desirable to use, as the initial fabric substrate, a permeable fabric of the invention. Further, the same results can be achieved even when the interlining fabric is a non-woven fabric.
  • the invention includes also non-woven or other fabric comprising fibres of cellulose, wool or polyamide
  • the invention also includes laminates of the fabric carrying a heat and pressure-sensitive adhesive coating covered by a release substrate, and heat bonded laminates formed by hot pressing the fabric carrying the adhesive coating on to an outer fabric.
  • the fabric having the impregnation with polyethylene glycol has high permeability, as is preferred, the resultant laminate has good permeability, good moisture transmission, and a good permanent bond between the interlining substrate and the outer fabric.
  • Fabrics according to the invention which are to give a cooling sensation when warm can be sportswear, casual wear or loose external wear such as mens head wear Ghuttra and Schmagh; ladies head-dress such as Sheliagh and Hejab,• mens outer wear such as Thobe or Dish Dasha and ladies outer wear such as Abba.
  • a cotton voile used for the manufacture of Ghuttra made from 2/100 's cc yarn and having 60th/inch in both warp and weft direction.
  • the yarn had been gas singed and mercerised before weaving.
  • the fabric was again singed and mercerised and then boiled in a lOg/1 solution of Caustic Soda in a kier for 8 hours.
