Abstract

A heretofore unknown textile is made of woven or knitted threads or yarn, substantially consisting of a mixture of cotton fibres and fibres of rabbit wool, in particular Angora wool, the fibres having essentially the same length, e.g. 2-5 cm. A fibres mixture of 15-70 % by weight of Angora wool and 85-30 % by weight of cotton is used. The textile is unique particularly in having great softness and having good washability, the optimum properties in this respect being achieved when the mixing of the fibres and spinning are performed at a temperature of 30°C and a relative air humidity of 60-90 %, preferably 85-80 %. Subsequent repeated washing and drying additionally develops the advantageous physical and mechanical properties of the product.

Description

A textile and a method of making it
The present invention concerns a woven or knitted textile with a content of rabbit wool, in particular Angora wool. The invention moreover concerns a method of making such a textile.
Angora rabbits are a white rabbit race having a valuable, long-haired, silky fur. The hair or the wool can be spun to fine yarn, which can be woven to soft textiles having excellent heat-insulating properties and a high moisture- absorbing capacity.
Usually, wool from Angora rabbits has approximately the same fibre length as sheepswool, generally about 6-8 cm, and can therefore be spun to threads and yarn by means of the same spinning machines as are used for sheepswool.
Angora yarn and textiles of it are natural products which do not cause allergic reactions in humans. They are also so soft that they have no itching or irritating effect on the skin. Owing to the moisture and sweat absorbing pro¬ perties Angora yarn is extremely suitable and in great de- mand for making warm underwear worn directly on the skin.
An essential drawback of Angora wool textiles is their poor washability. Thus, they will only stand washing a few times, since they tend to filter and wear out easily. Further, the spinning process is difficult and very sensi¬ tive so that the temperature, the degree of moisture and other process conditions are to be adjusted optimally.
To overcome the drawbacks of the poor washability and also to improve the spinning properties, it has been attempted to mix Angora wool with textile fibres of another type, such as sheepswool or various artificial fibres, such as polyamides, polyesters or polyacrylic fibres. One of the most widely known and best textiles of this type is made from e.g.
40% Angora wool
30% sheepswool and
30% polyamide or polyacrylic fibres.
Textiles made of such a mixture are commercially available from the firm Medima in Maulburg in the Southern Germany. These textiles are not pleasant to the skin owing to their content of the mentioned chemo fibres. The heat insulation and the moisture absorption are somewhat reduced. These textiles irritate the skin to some degree, since the sheepswool generates an itching feel, and artificial fibres can cause allergic reactions. On the other hand, the chemo fibres impart improved washability and stability to the textiles. However, the washability is extremely poor in comparison with e.g. cotton underwear.
An object of the present invention is to make a woven or knitted textile having the good properties of the Angora wool, but not its poor properties.
A primary object of the invention is to improve the dimen¬ sional stability, fit and washability of the Angora wool without impairing the softness, heat insulation capacity, moisture absorption capacity and other advantageous pro- perties of the wool.
Cotton is comfortable as underwear because it directs moisture away from the body and counteracts overheating of the skin. Cotton has very good washability and does not cause aller¬ gy. However, cotton has a poor heat insulation capacity and is therefore unsuitable for the making of warm under¬ wear.
In the past, it has not been possible to spin normal fibres of Angora rabbit wool together with cotton fibres because a cotton spinning machine cannot spin Angora rabbit wool. However, it has surprisingly been found pos- sible to solve this problem according to the invention by using Angora wool having approximately the same fibre length as the fibres of cotton instead of normal Angora wool.
Thus, the invention concerns a textile woven or knitted of spun threads, said textile being characterized in that the threads mainly consist of a mixture of cotton fibres and fibres of rabbit wool, in particular Angora wool, the fibres having essentially the same length.
In the method of the invention it is possible to use ordi¬ nary cotton spinning machines so that it is not necessary to use special spinning machines, such as wool spinning machines.
The preferred composition of the threads is 15-70% by weight of Angora wool and 85-30% by weight of cotton, in particular 30-60% by weight of Angora wool and 70-40% by weight of cotton. The best results have been achieved with 40-55% by weight of Angora wool and 60-45% by weight of cotton, e.g. Angora wool and cotton in the ratio 50:50.
As mentioned, the fibres of the two materials are to have approximately the same length, preferably 2-5 cm, in par- ticular 3-4 cm, e.g. 3.5 cm. The present textile is expediently manufactured by the method of the invention, which is characterized by the subject-matter stated in the characterizing portion of claim 3, i.e. fibres of cotton are mixed with fibres of Angora wool having approximately the same fibre lenght as the cotton, following which the fibre mixture is spun, and the spun threads are woven or knitted to the textile.
According to an expedient embodiment of the method of the invention, the process, preferably both mixing and spinning of the fibres, is carried out at 20-35°C and 90- 60% relative humidity, in particular at about 30°C and about 80% relative humidity.
The textile obtains optimum properties, in particular with respect to softness and absorption capacity, if the tex¬ tile is washed and dried repeatedly after weaving or knit¬ ting e.g. 3-8 times, expediently 6-7 times.
The present method provides a significantly more healthy and also considerably more inexpensive product than in the making of Angora-containing textiles having a content of chemo fibres. In relation to the above-mentioned product commercially available from the firm Medima an improvement is obtained in particular with respect to softness and sweat and other moisture absorption capacity and especial¬ ly good washability.
The invention will be illustrated more fully below by means of an example, it being appreciated that the various parameters can be varied arbitrarily within the scope of the claims.
EXAMPLE Equal parts by weight of Angora wool having a fibre length between 3 and 4 cm and cotton having a corresponding fibre length are mixed in an atmosphere with a temperature of 30°C and 85% relative humidity. The resulting mixture of fibres is then spun by means of a traditional cotton spinning machine, but in an atmosphere with a temperature of 30°C and a relative humidity of 85%.
The spun threads or yarn are knitted in a manner known per se to provide a vest, which is washed and dried after the manufacture. Washing and drying are repeated for a total of 6 times.
The garments made in this manner are soft and pleasant to wear and can be used without inconvenience to the user for an extended period of time without any risk of allergy reactions. Further, they can be washed in washing machines at temperatures higher than normal for Angora, e.g. 60°C. The underwear in question can be sterilized at boiling temperature in open containers and is therefore extremely useful at hospitals and the like.
