Definitions

  • the present invention relates to the use of soil release polymers as ironing aids in fabric treatment compositions.
  • the invention further relates to the use of fabric treatment compositions to provide anti-wrinkle properties and/or ease of ironing benefits to a fabric treated therewith, wherein the composition comprises at least one soil release polymer.
  • the invention relates to a method of reducing the creasing of fabric and to a method of providing ease of ironing benefits.
  • Ironing of fabrics after laundering is generally regarded as one of the most unpopular household chores. There have, to date, been two approaches taken to making ironing less of a household chore.
  • the first approach has been to make the ironing process easier (involving less time and effort for the person doing the ironing). This is referred to herein as an ease of ironing effect.
  • silicone oils have been used in rinse conditioners to give this effect.
  • the second approach has been to try to prevent garments becoming creased (this is referred to herein as an anti- creasing effect) during the laundering process, thus eliminating the need for ironing.
  • This approach is disclosed in e.g. EP 150 872 .
  • This second approach has several additional advantages over the first; firstly, it is attractive to consumers because they will not have to iron the fabrics at all (thus saving time and effort, and, avoiding a household chore completely) and secondly it reduces energy consumption and hence is environmentally favorable.
  • This second approach has generally been found to be more difficult to achieve. However, it has been found that increased levels of active ingredients are often required in the product to achieve the effect.
  • the present invention is directed towards providing reduced creasing of fabric during laundering and/or easier ironing of fabric that has been laundered.
  • soil release polymers contained in fabric treatment compositions provide for anti-wrinkle effects and/or ease of ironing effects. Furthermore, wearing comfort after ironing of the fabric is improved due to moisture managing properties of the soil release polymers.
  • Soil release polymers are well known ingredients in laundry detergent compositions and fabric softener components.
  • US 4, 007, 305 ; US 4,702,857 ; EP 0 707 627 ; EP 991 743 and US 7 087 572 relate to soil-release polymers and/or to their use as ingredients in fabric care compositions.
  • the present invention therefore relates to the use of a fabric treatment composition to provide anti-wrinkle properties and/or ease or ironing benefits to a fabric treated therewith, wherein said composition comprises at least one soil release polymer.
  • the present invention relates to a method of reducing the creasing of fabric by applying thereto during a laundering operation the composition as defined herein.
  • the invention relates to a method of providing ease of ironing benefits to a fabric by
  • the present invention relates to the use of soil release polymers as ironing aids in fabric treatment compositions.
  • At least one relates to one or more, i.e. 1, 2, 3, 4, 5, 6, 7, 8, 9, or more. If used in combination with a compound, the term does not relate to the absolute number of molecules but rather to the number of different types of said compound. "at least one surfactant” thus means that at least one type but that also 2 or more different surfactant types can be present.
  • viscosities referred to herein are viscosities measured at 20°C by a Brookfield LVT, Spindle No. 3 at 12 rpm.
  • Free of means that the referenced composition does not contain more than 0.5 wt.%, preferably no more than 0.1 wt.%, more preferably no more than 0.05 wt.% of said component relative to the total weight of the composition. Most preferably, said component is not contained at all.

  • the composition may be used as fabric spray for pre- or post-washing treatment of fabrics.
  • the present invention is based on the inventors' surprising finding that by use of soil release polymers in fabric treatment compositions, anti-wrinkle effects and/or ease or ironing effects may be achieved. Furthermore, wearing comfort after ironing of the fabric is improved due to moisture managing properties of the soil release polymers.
  • the present invention relates to a fabric treatment composition, wherein the fabric treatment composition comprises at least one soil release polymer.
  • soil release polymer refers to polymeric soil release agents having soil release properties, i.e. having the property to enhance the cleaning efficacy of the cleaning composition by improving release of greasy and oil during the laundry process.
  • Polymeric soil release agents are characterized by having both hydrophilic segments, to hydrophilize the surface of hydrophobic fibers, such as polyester and nylon, and hydrophobic segments, to deposit upon hydrophobic fibers and remain adhered thereto through completion of washing and rinsing cycles and, thus, serve as an anchor for the hydrophilic segments. This is commonly done to enable stains occurring subsequent to treatment with the soil release agent to be more easily removed in later washing procedures.

  • Example 2 Determination of static and dynamic friction force during ironing
  • an iron is pulled by a motor over the length of 100 cm over the surface of the test fabric with a velocity of 1 m/25 s.
  • the motor is hanged up free and connected with a force sensor. Just in the moment when the iron is torn by the motor, it pulls at the force sensor.
  • the force sensor shows the force [N], which is necessary to pull the iron over the textile. Static and dynamic friction forces were determined accordingly.
  • Static frication is the friction that is needed to overcome the breakaway force. It is described as follows: the highest values which is determined within the 1 st second is interpreted as static friction force caused by breakaway force.
  • Dynamic friction is the friction that is needed to pull the iron over the whole measuring unit after static state by taking all measured values into account that are determined from the 2 nd second until the end of measuring cycle.
  • the iron was adjusted at an ironing temperature of three dots respectively for measurement of polyester/cotton fabrics two dots were adjusted.
  • each sample was approximately (120 x 20) cm 2 .
  • Six samples per product and type of test fabric were used for the determination. Each of the six replicates was measured in total two times, one time on untreated (not ironed areas) and one time on already ironed areas. Therefore run 1 (untreated areas) and run 2 (already ironed areas) was averaged.
  • the sole plate of the iron was cleaned with isopropyl alcohol every time after measurement of six samples per product.
