FOOTWEAR The present invention relates to insocks for foot-wear and in particular to such an insock which may reduce odours which sometimes occur due to feet sweating or perspiring. This application is a continuation in part of application Ser. No. 140,255 filed on May 4, 1971, now abandoned.

It is a particular object of the present invention to provide such insocks which have good surface abrasion resistance whilst retaining a high absorption potential for odours. It is a further object to provide insocks which do not disintegrate readily during wear.

According to the present invention these objects are achieved by providing an insock for insertion into the shoe, said insock comprising a fibrous web or mat loaded with active carbon and a binder, the binder being disposed predominantly at and adjacent to the surfaces of the web or mat.-

The invention will be better understood by reference to the drawings wherein:

FIG. 1 is a plan view of an insock according to the invention.

FIG. 2 is a section of the plan view of FIG. 1 taken at 2-2.

FIG. 3 is another sectional view of the insock and FIG. 3A is a graph of cross-sectional position of the insock versus dry binder concentration.

It is preferred that the insock is of such a shape that it is able to cover substantially all of the area of inner sole of the shoe and a plan view of such an insock is shown in FIG. 1.

The fibers may be natural or synthetic and are preferably wood fibers.

It is preferred that the web or mat be supported by a backing material. The backing material may be, for

example, paper; a cloth obtained from natural sources,

e.g., a cotton scrim, flannelette or swansdown; or a synthetic material such as nylon. In the cross-sectional view of FIG. 2 a layer of flannelette' is ilustrated being adhered to the carbon/fibre layer.

The backing material may have one or two fluffy" surfaces, and preferably at least one and this arranged so as to be in contact with the fibrous web. The fibres of the fluffy surface intertwine with the web material thereby aiding the bonding of the backing material to the web substantially.

The insock may also have a layer of foam e.g. polyurethane foam, attached thereto. The foam gives increased strength and a pleasant spring in the step of the wearer.

The insock material can be of any desired thickness but preferably has a total thickness of from about 30 to 100 thousands of an inch, (about 0.75 mm to 2.5 mm.).

In a preferred embodiment the web comprises 20 to 65 percent by weight based on the air dry loaded'web, of active carbon.

The binder material may be any of the types known in the art provided it is compatible with the materials constituting the web and any backing material. Preferred binders include natural and synthetic latices especially acrylic and acrylonitrile butadiene latices.

It is preferable to use from to 30 percent by weight of binder, based on the air dry loaded web. These amounts have been found to give satisfactory abrasion resistance at the surface without significantly decreasing the absorption potential of the loaded web.

In an especially preferred embodiment therefore,

adjacent the surface of the mat will reachlevels at which the absorption potential of the web is significantly affected. Preferably the amount of binder incorporated should be such as to minimise the loss of absorption potential of the active carbon to less than l0 percent, e.g., about 5 percent.

The active carbon loaded web may be made by methods known in the art such as deposition of web components including the active carbon filler, from a fluid media, for example water or air.

It is especially preferred that the web or mat be made by the air-laying process described and claimed in our corresponding application Ser. No. 842889 Filed on July 18, 1969;

The incorporation of the binder in the carbon loaded web may be effected by impregnation with an aqueous latex, the latex being allowed to migrate freely within the web. Such migration takes place towards the surface of the web so that the end result is a web in which the binder is predominantly at and adjacent to the surfaces of the web. In this way the resulting web has the advantage of good surface abrasion resistance because of the high concentration of binder at and near to the surface whilst retaining high absorption potential because of the low concentration of binder within the web. A graph of cross-sectional position within the web versus dry binder concentration is shown in FIG. 3A and it is seen that the concentration is higher near the surfaces than at the middle of the web. The insock of the invention therefore possesses not only the high absorption potential required but also good abrasion resistance and mechanical strength coupled with positive retention of the active carbon particles.

The invention will be further described by reference to the following examples which are descriptive only and not to be regarded as limiting.

EXAMPLE I A fibrous web was formed by the air-laying-method described in application Ser. No. 842889 filed on July 18, 1969, now abandoned on to a muslin scrim as backing material of 50 X 40 mesh and of thickness 0.009 inches, so as to form a laminate sheet.

The web had the following composition:

Active carbon filler about 35% Butadiene acrylonitrile latex binder about 15% Basic woodpulp fibres remainder From the laminate sheet, two insocks were cut out, of a shape and size such that, when inserted into a pair of shoes, each was able to substantially cover the inner soles thereof, and having the muslin scrim uppermost so as to be able to make contact with the foot of the wearer.

' These insocks were worn in shoes of a person suffering very badly from excessively sweating feet and they 3 4 efficiently removed ObjeCtiOHabIe OdOU o the nal surface of the web.

The effect, due to cross-linking is to reduce the degree of migration of the binder so that the strength of the middle section is higher. The amount of migration is still sufficient to provide good absorption potential. Too great an increase in wet strength additive would however reduce the absorption Potential to unas sp e slsys The drying conditions also affect the degree of migration of binder and these should be selected to give a satisfactory level of migration of binder towards the surfaces of the web. The conditions in Example 3 give rise to slightly less migration than those in Example 2.
