Problems solved by technology

However, there are numerous disadvantages associated with repeated use of conventional laundry treatment compositions and/or the actual laundry process; one of these being a fairly harsh mechanical and/or chemical treatment of textiles in the laundry process.
Textiles can be damaged in several ways as a result of repeated laundering and/or wear.
Textile pilling and loss of textile surface appearance e.g. fuzzing, shrinkage (or expansion), loss of colour from the textile or running of colour on the textile (usually termed `dye transfer`) are some of the common problems associated with repeated laundering.
These prob

[0120] Method of Preparation of Voranol Iso-Thiouronium Compounds

[0121] Voranol CP3055 .TM. (ex-Dow Chemicals) (29.4 g, 0.01 moles, mw 2940) was dissolved in toluene 50 mls. To this was added 3-bromopropionic acid (4.95 g, 3.3 equivalents ex Aldrich) and p-toluene sulphonic acid (1 g) to act as an acid catalyst. The solution was stirred by means of a magnetic follower on a hot plate. The solution was refluxed with a Dean and Stark distillation trap. After 1.5 hours no more water was seen to azeotrope from the reaction vessel into the side arm. The reaction was stopped and allowed to cool.

[0122] The toluene / Voranol solution was shaken with solution of sodium bicarbonate (10 g / l). This was repeated five times, until the solution was seen not to effervesce from the evolution of carbon dioxide gas and the water was at a neutral pH. The two phases were separated and the toluene was removed from the Voranol compound by rotary evaporation. After drying in vacuo over calcium chloride the yi...

[0129] Method of Preparation of Jeffamine Iso-Thiouronium Compounds

[0130] Jeffamine T-3000 .TM. (ex-Huntsman Corp) (30 g, 0.01 m mw.about.3000) was dissolved in acetone (50 mls) and cooled to below 5.degree. C. with an ice bath. Sodium carbonate (2 g) was added to the solution with stirring. 3-Chloropropionyl chloride (4.19 g 3.3 equivalents) was dripped into the solution of Jeffamine T-3000 over a period of one hour. The temperature of the solution was kept below 5.degree. C. After the addition of the acid chloride, the temperature was allowed to rise to room temperature over a period of one hour. The solution was then filtered to remove the solid sodium carbonate. The acetone was removed on a rotary evaporator. The solution was then washed five times with a sodium bicarbonate solution (10 g / l.sup.-1) until the washings were neutral. The product was then separated from the aqueous solution using a separating funnel and dried over silica in vacuo.

[0138] Method of Preparation of Lupasol Isothiouronium Compounds

[0139] Lupasol G-20.TM. (ex-BASF) (39 g 0.03 moles was dissolved in ethanol (50 mls) and cooled to below 5.degree. C. with an ice bath.

[0140] Sodium carbonate (3 g) was added to the solution with stirring. 3-Chloropropionyl chloride (14.22 g, 0.09 moles, 3 equivalents) was dripped into the Lupasol solution over a period of two hours. The temperature of the solution was kept below 5.degree. C. After the addition of the acid chloride, the temperature was allowed to rise to room temperature over a period of one hour. The solution was then filtered to remove the solid sodium carbonate. The product was not isolated using the methods described previously since the compound is highly water soluble and recovery from an aqueous solution would haven proven difficult. A small quantity was isolated for structure confirmation. A new peak was seen at 1637 cm.sup.-1, indicating the presence of an amide group.

Abstract

A process for the treatment of non-keratinaceous textiles, preferably cellulosic fibres, which comprises the step of treating the textiles with a composition comprising: a polymer comprising at least one protected thiol group, wherein the protecting group is labile under domestic washing conditions, and a textile compatible carrier. Under domestic washing conditions the polymer forms reactive thiol groups which are capable of causing covalent cross-linking of the polymer. Preferably, the thiol group is protected as an isothiouronium group.

Description

[0001] This invention relates to textile care compositions and, in particular, to the use of the textile care compositions in a domestic laundering process to reduce fibre damage and / or improve textile dimensional stability.BACKGROUND AND PRIOR ART[0002] The laundry process generally has several benefits for textiles, the most common being to remove dirt and stains from the textile during the wash cycle and to soften the textile during the rinse cycle. However, there are numerous disadvantages associated with repeated use of conventional laundry treatment compositions and / or the actual laundry process; one of these being a fairly harsh mechanical and / or chemical treatment of textiles in the laundry process.[0003] Textiles can be damaged in several ways as a result of repeated laundering and / or wear. Textile pilling and loss of textile surface appearance e.g. fuzzing, shrinkage (or expansion), loss of colour from the textile or running of colour on the textile (usually termed `dye tr...
