AI Technical Summary

Benefits of technology

The treatment composition reduces inter-yarn friction, improving fabric softness, ease of ironing, and anti-abrasion properties, with performance exceeding conventional rinse conditioner systems, as assessed by Kawabata shear measurements.

Problems solved by technology

Fabrics in general, and cotton in particular, are prone to the formation of creases before, during and after laundering and drying.
In order to remove such creases from the fabric, a considerable amount of time and effort must be spent ironing upon each occasion of laundering and drying.
However, such treatments tend to make the fabric stiff and relatively easy to tear.

Alcoholic, Base-Free Synthesis of Magnesium Amino-Containing (Organo)Phyllosilicates

[0166] Examples 6 to 8 employed an alternative method for preparation of amino-containing magnesium organoclays employed base-free, alcoholic conditions. Magnesium chloride hexahydrate, MgCl2.6H2O, was dissolved in ethanol or methanol and organotrialkoxysilane was added with rapid stirring. Immediate clouding of the solution followed by copious precipitation ensued after 5 minutes stirring. The reaction mixture was left stirring at room temperature for a minimum of 1 hour. The product of reaction was isolated by filtration and washed thoroughly with ethanol. The products of the reaction may be redispersed in ethanol or water and retained as a slurry, dried in air with or without heating, dried under vacuum with or without heating or freeze-dried.

[0167] The amount of organotrialkoxysilane added in each case was equal to the stoichiometric amount required to synthesise materials with Si / Mg=1.33.

[0169] The utility of the pendant epoxide group 3-glycidoxypropyl on the clay of Example 5 (epoxide clay) to post-functionalisation by nucleophiles was utilised to introduce alternative functional groups.

example 9

[0170] The epoxide group was initially ring-opened by heating with an excess of ethylenediamine to give an amine-terminated clay. After continuous extraction with acetone the dried clay contained nitrogen by elemental analysis. The prepared amino clay was then reacted with succinic anhydride to give a clay with an acid functionality, the FTIR of the clay showed evidence of an amide and carboxylicacid carbonyl stretch.

Abstract

Fabric treatment compositions comprising a textile compatible carrier and particles having a layered structure comprising oxygen atoms and silicon and / or phosphorus atoms and comprising organic functional groups which are bonded to silicon and / or phosphorus atoms by direct covalent bonds between the silicon and / or phosphorus atoms and a carbon atom. The functional groups are selected to impart lubricating properties to the particles.

Description

[0001] This is a continuation of Ser. No. 10 / 406,952 filed Apr. 4, 2003TECHNICAL FIELD [0002] This invention relates to fabric treatment compositions, to their use in the treatment of fabric and to a method of treating fabric with the compositions. BACKGROUND AND PRIOR ART [0003] It is known that the physical properties of fabrics can be modified by certain treatments. For example, fabric may be treated in order to modify its physical properties either in an industrial pretreatment or during laundering. [0004] Fabrics in general, and cotton in particular, are prone to the formation of creases before, during and after laundering and drying. In order to remove such creases from the fabric, a considerable amount of time and effort must be spent ironing upon each occasion of laundering and drying. The terms “crease” and “wrinkle” and related terms, such as “anti-crease” and “anti-wrinkle”, refer to non-permanent deformations in the fabric which can be removed by flattening at elevated t...
