- the alpaca is considered among the 5 most eco-friendly animals on the planet since the pads on its paws prevent abuse of the ground. Also, their way of feeding is special since they do not pull up the grass but rather cut it, which encourages its growth. In relation to their waste, they are low in acidity which allows them to be easily converted into natural fertilizer for the soil. They are raised in freedom, feeding on the grasses of the high Andes, making them organic animals and obtaining the fiber does not harm the animal, since it is done by shearing, which must be done once a year since these animals do not They shed their hair naturally. The manufacturing process of these fibers does not require high water consumption.
- Alpaca fiber has a special characteristic as it is a fiber that contains an air pocket inside, which allows for correct thermoregulation. This is the reason why alpacas are comfortable in low temperatures in high areas of the Andes, but also while the sun shines they are also comfortable when temperatures rise. Also, alpaca fiber has the characteristic of quick drying and is a soft and light short fiber.
- the present invention makes a contribution to the state of the art since garments, for example, jackets filled with the material based on alpaca fiber according to the present invention, provide a lighter, more versatile, final product. warm and easy to wash, also being friendly to the planet and people by using a process with minimal or almost zero waste since the waste that results from the combination of natural and synthetic fibers in one process can enter a new process as recovered fiber .

- the synthetic fibers according to the present invention may comprise virgin polyester which may be 7D HC silicone polyester (conjugated hollow fiber) and may be in a minimum proportion of 12% and a maximum of 35% by weight of the total mixture of the final product. Also, it may comprise "lowmelt” polyester, which is polyester with a low melting point and may be in a minimum proportion of 12% and a maximum of 20% by weight of the total mixture of the final product.
- the recycled polyester can be, for example, recycled PET (RPET) and can be in a minimum proportion of 6% and a maximum of 24% by weight of the total mixture of the final product and the recovered fiber is nappa waste (7D siliconized polyester HC) or the fibers that result after mixing the product resulting from the waste of previous production processes and can be in a proportion between 1% and 5% by weight of the total mixture of the final product.
- RPET recycled PET
- the product or composition based on alpaca fiber according to the present invention can have a weight of from 80 grams per square meter (g/m 2 ) to 200 grams per square meter (g/m 2 ). more preferably between 80 g/m 2 and 140 g/m 2 , for example, 80 g/m 2 , 100 g/m 2 and 120 g/m 2 where the grammage determines the thickness of the product based on alpaca fibers and therefore the thickness of the article of clothing, for example, a jacket, jacket or other article of clothing with thermal insulation filling material.

- the present invention is also directed to the process for obtaining the product or composition based on alpaca fibers as a filling material for clothing, which includes the steps of: a) Providing alpaca fiber alpaca; b) Select the alpaca fibers; c) Clean the alpaca fibers; d) Card the alpaca fibers in order to achieve a homogeneous material; e) Provide synthetic fibers; f) Weigh the natural alpaca fiber and the synthetic fibers so that the final mixture at this stage comprises between 65% and 75% alpaca fiber and between 25% and 35% synthetic fiber; g) Enter the mixture obtained in step f) into a hopper and mix the fibers; h) Enter the result of step g) into a crushing machine that joins the different fibers until reaching a homogeneous felt-type material; i) Unload the felt obtained in step h) onto a conveyor belt that passes through an oven and subject the felt to a temperature between 90°C and 170°C
- step a) the alpaca fiber is obtained through shearing, which does not cause any harm to the animal.
- step b) the fiber is separated by different qualities.
- alpaca fibers with a length between 3 cm and 7 cm or more are selected, mainly Huarizo fibers that are approximately 7 cm.
- Fine fibers such as baby alpaca, alpaca fleece, alpaca medium fleece, as well as thick alpaca can also be used.
- step c) cleaning consists of removing impurities, such as pieces of wood, grass or small stones that may become tangled in the animal's hair.
- step d) carding can be carried out with a manual or mechanical carder with which a more homogeneous material is achieved.
- the synthetic fibers that can be used in the present invention can be polyester, for example, 7D HC silicone polyester (hollow conjugated) where the synthetic fiber allows the mixture obtained to be soft and spongy.
- Other options for synthetic fibers that can be used in combination or mixture with the 7D HC (hollow conjugated) silicone polyester in the process of the present invention are “lowmelt” synthetic fiber (low melting polyester), which is a solid fiber that helps the integration of the rest of the materials. The proportion of this virgin low melting synthetic fiber is between 12% and 20% of the total weight of the total mixture.
- solid recycled polyester can be used in a proportion such that it does not affect the resilience of the material since the recycled polyester fiber is less versatile, in where material resilience is understood as the ability of said material to recover its original state after being squeezed.
- the recovered fiber that participates in the process of the present invention is nappa fiber (7D HC siliconized polyester) or fibers left over from the mixture of the product itself based on alpaca fiber according to the present invention. from losses from previous production processes and can be in a proportion between 1% and 5% by total weight of the total mixture of the final product.

- the highest percentages in this process are due to the fact that later when going through step i) which includes subjecting the felt to a temperature between 90°C and 170°C, a part of the natural fiber is affected by the temperature losing moisture, so these values guarantee the established percentage for the final product.
- step g) the weighed materials and in their defined percentages are placed in a hopper, preferably in a type of blender where all the materials are mixed until a homogeneous mixture is obtained.
- step h) after mixing in the hopper, said mixture is passed through a crushing machine which includes rollers, which join the different fibers until achieving a homogeneous felt-type material with desired width characteristics. and thickness.
- a crushing machine which includes rollers, which join the different fibers until achieving a homogeneous felt-type material with desired width characteristics. and thickness.
- the width of the felt can be any desirable width depending on the width of the dressmaking work tables, preferably, but not limited to, the width can be between 50 cm and 300 cm. More preferably 150 cm, which can be a comfortable measurement for tailoring and also reduces shrinkage.
- step i) the felt obtained in the previous stage can be unloaded manually or mechanically on a conveyor belt that advances at a speed between 2 and 10 meters per minute (m/min) which passes through an oven that It is at a temperature between 90°C and 170°C. With the speed indicated above, the melting and stabilization of the mixture is optimally achieved to obtain the product based on alpaca fibers as a filling material for clothing in accordance with the present invention.
- the final percentage of each of the components in the final product based on alpaca fibers is between 40% and 70% alpaca fiber, between 25% and 55% synthetic fibers and 5% recovered fiber.
- the proportion of recycled fiber is between 6% and 24% by weight of the total mixture of the final product and the virgin polyester in a proportion of between 12% and 35% by weight of the total mixture of the final product and the lowmelt polyester in a proportion between 12% and 20% by weight of the total mixture of the final product.
