William Lee, a student of the British Theological Seminary, invented a machine that sews socks by hand, which is 6 times faster than hand sewing. This is the originator of the sewing machine. At this time, the ladies also began to wear socks. Industrialized socks production began in 1860. The hosiery industry is always looking for new materials to replace the scarce and expensive real silk. The production of blended yarns has made the hosiery industry a great success. In 1928, DuPont showed the first pair of nylon socks, and Bayer launched polypropylene socks. In 1940, high-barrel nylon stockings created the highest sales record in history in the United States, and began to become ordinary daily necessities. The birth of pantyhose In the 1960s, the miniskirts designed by British designer Mary Quant swept the world. Skirts were getting shorter and shorter, high stockings dwarfed, garters were abandoned, socks and panties became one, and pantyhose was born. Its comfort and convenience have made women all over the world love it even today, and this model is enduring. Socks are divided into cotton yarn socks, real silk socks, wool socks, nylon stockings, nylon silk elastic stockings and various interwoven blended socks according to the raw materials. The fastness and abrasion resistance of cotton yarn socks are poor. Wool socks are generally knitted with double-strand knitted velvet, which has strong warmth retention, good elasticity and moisture absorption. Silk stockings are soft and smooth, but because the silk is relatively smooth, the loops are easy to fall off. Nylon stockings and elastic nylon stockings have good strength and wear resistance, and elastic nylon stockings also have the advantages of fluffy, soft, elastic and good warmth retention. The most worth mentioning but not known to most people is a special kind of socks called “Han Ma”, socks made from a special material “Han Ma”. Then, what is “Han Ma”, according to historical records, Hemp originated in China, and the garments made of hemp have various functions such as moisture absorption, ventilation, comfort, heat dissipation, mildew resistance, antibacterial, anti-radiation, UV protection, and sound absorption, etc., and can be used for both military and civilian use. In terms of the effect of making antibacterial socks, it has been widely praised. Hemp is the earliest natural fiber used in fabrics by humans. It has the reputation of “the source of national textiles, the ancestor of clothing for thousands of years”, and its cultivation history has at least 8,000 years.
