Hand knitting yarn made from nature fibers are more comfortable

Camel Family (Alpaca/Llama/Camel/Vicuna): Yarns made from the fibers of these animals are very soft, lustrous, lightweight and warm. Alpaca is often used for the manufacture of warm, luxurious apparel. The down hairs of the Llama will produce a soft knitting wool yarn also suitable for the manufacture of apparel. Camel hair is from the extremely soft and fine fur from the undercoat of the camel. Vicuna is the world´s most valuable fiber. Vicuna is small and wild and belongs to the Camel family. It yields the finest animal fiber in the world. This fiber is rare and very expensive.

Silk: Silk is a natural protein fibre containing about 70-75% of actual fiber fibroin secreted from two salivary glands in the head of the silkworm larva, and about 25-30% sericin, a gum which cements the two filaments together. Silk of the finest quality is obtained from the unwound filament of the silkworm cocoon. To obtain lower grades of silk, broken or waste filaments and damaged cocoons are retained, treated to remove the sericin, and combed. This is then processed into hand knitting yarn, marketed as spun silk, which is inferior in character to the reeled product and much cheaper.  Low grade silk is made from damaged cocoons that were spoiled by emerging moths used for breeding stock. Filaments from the coarse outer portion of the cocoon, which is removed by brushing before reeling, and the inner portion of the cocoon, which remains after reeling the raw silk, are mixed with silk from damaged cocoons to make low grade silk. Silk has a high natural lustre and sheen of a white or cream color. It has a reputation as a luxurious and sensuous fabric, retains its shape, drapes well, caresses the figure, and shimmers with a luster all its own. Silk is naturally hypoallergenic, yet is still breathable; it absorbs moisture and reduces humidity, which makes it cool in the summer and warm in the winter.

The two types of nature fibers are from animals, there are plant fibers, such as, cotton, linen, rayon, ramie, hemp. Plant fibers and animal fiber are more eco friendly and absorbent, breathable, but bad corrosion resistance than manufactured fibers.
