1279 (54) Title: SOFTENING AGENTS (57) Abstract A method for the treatment of natural or synthetic fibres, such as wool, cotton, nylon or acrylic, so as to impart a softer handle comprises treating the fibres with a polymer or prepolymer as defined. The method may be performed as either a continuous process or as a batch process.
kA WO 92/07132 PCT/GB91/01792- -1- SOFTENING AGENTS This invention relates to the novel use of known polymers and prepolymers as softening agents to improve the handle of both natural and synthetic fibres.
Traditionally employed softening agents have as their basis either fatty acid or reactive siloxane chemistry. In both cases, the use of such agents imparts a degree of hydrophobicity to the treated fibres. While attempts have been made to overcome this effect by the incorporation of hydrophilic groups, such as amino, quaternary ammonium and polyethylene oxide groups, these generally have the effect of reducing the softness of handle that can be achieved and some hydrophobicity nevertheless remains.
In addition, particularly in the case of fatty amide based softening agents, the effects are transitory and tend to be readily removed upon subsequent wet processing of the treated fibres or during domestic washing of the finished product. Consequently, it has been necessary either to re-soften the material by re-applying a softening agent (which is inefficient and uneconomic) or to tolerate a reduction in the level of softness following washing of the product.
British Patent Nos. 1470243 and 1533343 describe compounds containing aziridine radicals and their use for reducing the shrinkage and felting of protein fibres. One of the compounds disclosed is that sold under the trade name Basolan SW, and which is marketed as a hydrophilic polymer that is said to achieve a soft hydrophilic finish when applied to synthetic fibres.
1Et Y 1~1 WO 92/07132 PC7/GB91/01792 2 The.present invention seeks to provide improved softening agents suitable for use with both natural and synthetic fibres. The polymers and prepolymers employed for this purpose are the subject of our co-pending European Patent Application No.

The term "fibre reactive grouping" as used herein is to be understood as meaning a group having residual chemical reactivity such that it will be capable of causing a molecule to be bound to the surface of a fibre in such a way as not to be readily removable therefrom. Examples include the fibre reactive dyes in which a variety of reactive halogen groupings are sited on the molecule and which, during dyeing, react with hydroxy or amino functionalities on the fibre surface to produce a chemical bond. It will be understood that electrical bonding forces, rather than chemical forces, could be involved and that a "reaction" as such need not occur. The terminology further includes species which will be attracted to a fibre surface and bind themselves thereto by means of cross-linking mechanisms.
The term "polyfunctional reactive group" as used herein is to be understood as meaning a group which is capable of reacting with the amino functionality of compounds of formula I or II. The reactivity of group B needs to be complimentary to that of group R 1 in those compounds.
It will be understood that the polymers and Si ,1 F- IV WO 92/07132 PCT/GB91/01792 8 prepolymers may be derived from mixtures of one or more polyoxyalkyleneamines and that these may be joined by bridging groups. The bridging groups serve to link the polyoxyalkyleneamines and some examples of suitable groups were mentioned above. The bridging groups themselves could, of course, bear reactive species capable of reacting with fibres. It will also be appreciated that the bridging group B could be incorporated into the molecular structure, whilst the prepolymer is being applied to the fibre, as a separate reactive crosslinking agent.
The present invention further provides a method for the treatment of natural or synthetic fibres so as to impart a softer handle and which comprises treating the fibres with a polymer or prepolymer compound of the aforementioned type.
The softening agents and method of this invention may be applied to all types of natural and synthetic fibres, including nylon and acrylic. Thef are particularly suited to use with wool and cottQ,, including 100% cotton terry loop towelling, and to cotton or wool blends with synthetic fibres.
The softening agents of the invention may be presented for use in solution in a non aqueous solvent, such as perchloroethylene. More preferably, however, they are in the form of an aqueous solution, optionally with the addition of suitable dispersing I agents to reduce the viscosity of the solution. The total amount of polymer solids applied to the fibres is generally from 0.005 to 10.0% by weight, most preferably from 0.05 to The method of this invention can be performed as either a batch or continuous process using conventional equipment. For example, the softening agent may be applied aqueously by exhaustion on to the goods in a traditional long bath WG 92/07132 PCT/GB91/01792 -9method using suitable machinery, or may be padded onto fabric continuously or applied in foam or by suctionslot techniques. In addition, the agent may be applied to piece goods or fabric from a solvent such as perchloroethylene in suitable machinery.
If desired, the softening agents may be applied in combination with other resins, further softening agents, emulsifiers, pigments, binders fluorescent whitening agents or other materials to confer additional properties or benefits to the material.
It has surprisingly and advantageously been found that the use of polymers and prepolymers of this type as softening agents imparts rather different, and improved, properties to the treated fibres compared with conventional softeners. Not only is a very soft handle achieved, but the finish is also extremely hydrophilic and substantially more durable to subsequent washing or wet processing. The durable softness thus imparted results also in dimensional retention and elasticity in knit cotton structures without recourse to conventional cotton resin finishes.
As will be appreciated, this results in considerable benefits for both manufacturers and users of, for example, cotton towelling, bathrobes, underwear and leisurewear.
A further advantage of the softening agents of this invention arises from their extreme water dispersibility. Conventionally employed softening agents are emulsions which create problems of shear instability in such high shear situations as jet dyeing machines, suction slot evacuators, and filtration problems when treating yarn in package dyeing machines, when filtration effects can cause difficulties. These problems are reduced, or totally avoided, with the present softening agents.
I
/2 WO 92/07132 PCT/GB91/01792 A still further surprising aspect of the invention is that these softening agents, when used in combination with one or more conventional softening agents, can result in finishes with considerably superior handle and performance than may be expected.
Wash durability, handle and fuming during fabric heat setting, for example, are much improved. In some cases the improvement may be up to or above the levels achieved with either material alone, indicating a synergistic action. Examples of suitable "conventional" fabric softening agents include: oxidised polyethylene wax emulsions; silicone emulsions, especially emulsions of reactive organofunctional silicones, and more especially amonosilicones; fatty amide emulsions; and quaternised fatty amine emulsions.
The present invention will now be illustrated by the following Examples.

To this solution was added 155.3g of epichlorohydrin with efficient stiiring at room temperature in a reaction flask fitted with a water cooled reflux condenser. The mixture was then heated to boiling and reflux maintained for approximately 4 hours or until a clear or slightly turbid homogeneous solution is produced when 5 cm 3 of the reaction mix is mixed with 30 cm 3 water. The reaction mixture was then allowed to cool and used in subsequent experiments.
Example 2 Various textile samples were treated with the product of example 1 as follows: scoured goods were placed in a blank bath at a liquor ratio of 30:1 and the bath set to pH 6.5 to 7.0 at 25 0
C.
The required amount of softener -was added to the bath in prediluted form 1:10 with water. The bath was raised to 35 0
C
and then allowed to exhaust, as indicated by the disappearance of the slight turbidity from the bath, which usually took between 15 and 30 minutes. The goods were then removed, hydroextracted and dried in a tumble dryer at between 700 and 100 0 c.
The results of the tests are presented in Table 1.

Example 8 The products of Example 4 and Examples 7a and 7b were applied to a variety of knitted cotton fabrics (double jersey, single jersey, loopback interlock and pique). The softeners were applied by a) padding: the softeners were applied wet-on-wet to the fabrics from a solution containing 25g/l product, pH7, 25 0
C
at 100% pick-up and b) exhaustion: as given in Example using o.w.g. product. The fabrics were stenter dried and commercially finished then compared for handle and durability to washing against a standard fatty amide softener. A co-applied mixture of the product of Example 4 and a polyethylene wax emulsion (Bradsyn G, Hickson Welch Ltd) was also evaluated.
The relative handle and durability assessments were as follows.
In general, the handle before and after wash was superior when softeners were applied by a padding technique compared with exhaustion. Before washing the softeners were comparable in softness to the standard silicone softener (Edunine SE, ICI Colours Fine Chemicals); after wash, (3 x HLCC4<, the standard softener could be readily distinguished by its harsher handle.
The Example 4/polyethylene wax mixture performed particularly well on all fabric types, giving a cool, soft handle and excellent drape.
I,
WO 92/07132 PCT/GB91/01792 17 Example 9 The softening agents of the invention are particularly suited to use on towels and towelling fabric as a consequence of their superior hydrophilicity. The products were applied by a wet-onwet continuous pad treatment at 80% pick-up, from solutions containing 20-40g/l softener to Egyptian combed cotton towelling. The fabrics were tumble tried and finished as towels. A warm, soft handle is achieved with excellent rewettability, as compared with silicone- and fatty amide-type softeners. The new softeners impart a fuller, more luxurious feel to towelling and a silkier handle. The durability of the softeners was assessed by subjecting the towels to seven domestic washes, without additional fabric conditioner and line dried. The towels treated with the new softeners retain their original appearance, with a full, soft handle.
Example The product of Example 4 was compared for yellowing at high temperatures against standard silicone- and fatty amide-type softeners. The products were applied to 50/50 polyester/cotton by padding from solutions containing 1 g/l wetting agent (Fullwet PPT Ltd) and 10-40 g/l softener. The fabrics were padded to 100% pick-up then dried. Yellowing of the fabrics was assessed by heating the fabrics on an electrically-heated press for up to 3 minutes.
Temperature Comments 180 0 C Little difference between products 200 0 C Example 4 showed no yellowing at 1,2,3 mins at all levels. Other products yellowed slightly.
