Abstract

The present invention relates to a method for producing and manufacturing a textile yarn from domestic-animal hair, especially dog hair, the main objective of which is to utilize the fibres, discarded by pet shops and/or veterinary clinics, which originate from trimming the coats of domestic animals, such as poodles, bichon frisés, cocker spaniels, lhasa apsos, shih-tzus, Maltese, and Yorkshire terriers, and other existing breeds with a coat that needs trimming, and also cats, said production method comprising Step 1) Selective collection of domestic-animal hair, originating from coat trimming, from veterinary clinics and pet shops, Step 2) Separation, selection and sterilization of the hair previously gathered, Step 3) Mixing of the fibres selected in Step 2 with a percentage of waste-silk fibres, and Step 4) Industrialization and production of the textile yarn with a view to obtaining a mixture of the domestic-animal hair in the proportion of 70% (seventy per cent) selected, sterilized hair, plus 30% (thirty per cent) waste silk originating from the cocoons from the recycling of silk by-products.

Description

Descriptive report of the invention patent of "PROCESS OF PRODUCTION AND OBTAINING A TEXTILE WIRE FROM DOMESTIC ANIMAL HAIR".

The present invention relates to a process for producing and obtaining a textile yarn from the hair of domestic animals, especially dogs, the main purpose of which is to exploit the yarn from the animals of domestic animals, which are discarded pet shops and / or veterinary clinics such as poodle, bichon frize, cocker spaniel, lhasa apso, shih-tzu, maltese and yorkshire and other breeds whose hairs require coughing, including cats.

[002] Textile yarn is a thin, thin fiber of any textile material, especially that used for sewing. Most textile fibers, except for silk, are no more than a few centimeters in length, which is why the filament process is necessary. The yarn used in sewing is quite different from that used in weaving, since the yarns used in weaving do not have the need for high tensile strengths, since the fabric tension is analyzed as a whole as fabric after your weaving process.

There are some studies for the use of dog hairs, specifically those of the poodle breed, present, including, in the state of the art, present in the Brazilian patent BR 102014025807-8, which claims the constitution of an improvement in fabrics and clothes, as well as a textile yarn composed of 25% poodle dog hairs and 75% acrylic fibers, type: polyacrylonitrile mass (PAC), whose selection process discards the short fibers and then goes through a process of five baths using ammonium hydroxide and detergent, in addition to antistatic bath, mixing with the synthetic fibers until obtaining said textile yarn.

The problem that the present claim aims to solve is the disposal of domestic animal hairs in the environment, whether that of dogs or even cats, regardless of breed and color, thereby creating a yarn capable of being used in weaving fabrics for the production of clothing, handbags and footwear accessories for both human and domestic use.

Another problem that the present claim will solve is the amount of waste from all the domestic animals, with the consequent reduction of the waste, providing the reuse of material by means of recycling.

The yarn used in the fabric construction is an intermediate product, while the yarn applied at the seams is an end product. Sewing machines are very demanding for the yarn, Sewing Thread, so special attention is needed to the elasticity and lubrication, essential process for the good performance during the construction of the final product, therefore, the yarn obtained in the process of the present claim, it will be used only for weaving, in order to obtain textile blades.

Thus, in order to solve the problem described, it has been developed the present invention which will be more detailed, following the following steps:

[1] Step 1: Selective collection in veterinary clinics and pet shops, from domestic animal hair, from tosas.

[009] Step 2: Separation, selection and sterilization of previously collected hairs;

[010] Step 3: Mix the yarns selected in step 2 with a percentage of residual silk fibers.

[010] Step 4: Industrialization and production of textile yarn.

[01 1] Thus, the PROCESS OF PRODUCTION AND OBTAINING A

TEXTILE YARNS FROM DOMESTIC ANIMALS by the selective collection in veterinary clinics and pet-shops, of the hair of domestic animals, originating from coughs as described in step 1.

Step 2 takes care of the segregation of collected hairs, by color and average size of two centimeters above, since, to obtain the textile yarn, there must be the interlacing of each of the hairs to another by, so that the yarn is very small, below 2 centimeters, it hinders the interlacing process.

[013] After said selection of the hairs, there is then dry sterilization, which is done by means of ultraviolet light applications and / or ozone application.

[014] This dry sterilization process, in addition to being very effective is cheaper, simpler and more beneficial to the environment, than the process of chemical baths which is contained in the prior art, since, through sterilization by chemical baths , the water used in the various stages of the baths, is contaminated and has to be discarded, causing a new problem to the environment or, it must undergo a process of cleaning and purification, which is usually expensive and makes it unfeasible, thus impairing , the environment.

In the present claim, the pet hair blend will be in the proportion of 70% (seventy percent) selected and sterilized hair, plus 30% (thirty percent) residual silk.

[016] The silk raw material comes from the cocoon made by a caterpillar, the silkworm (Bombyx mori), in which a single caterpillar produces a single silk thread, which can reach 1, 3 km of extension. It occurs that in the extraction of the silk as natural fiber, there is always the auxiliary fibers, that is, the residual silk or by-product of the silk. Residual silk may be defined as that from cocoons which the adult chrysalis (silkworm) is removed with life and separated for reproduction, this being damaged and unsuitable for the industry and also the recycling of by-products of the same raw material.

The mixing of the pet hair with the residual silk, i.e. with the silkworm fiber, facilitates the cohesion of the fibers for the production of the long yarn, providing for this more strength and gloss.

In step 4, it is where the textile yarn industrialization of the present claim occurs where the hairs are brought to a machine called an integrated feeder opener which cleans and blends the fibers and, after blending the selected and sterilized hairs with the residual silk, the said mixture is taken to a carding machine or carding, and the mixing is effected several times in the carding machine, until a uniform and homogeneous mixture is obtained.

[019] After this step, the homogeneous mixture is brought to the other machine known as a roving machine, which produces the wick which in turn is taken to the ring spinning machine in order to produce the long fiber yarn, textile yarn which can be marketed to produce various fabrics.

Said long yarn may be used to weave fabrics which, by virtue thereof, may be used for the production of a range of desing and fashion products, such as handbags, footwear, clothing for both human and animal use.

[021] Thus, the present claim differs from the patent found in the state of the art, in that it uses the hairs of any domestic animal, not only poodle dogs, as well as the fact that it does not use synthetic fibers, nor chemical baths for sterilization.
