The 21st century is an era of diversity, where men, women and children are all looking for individuality and beauty. Clothing, as an indispensable item for people, naturally needs to meet people's individual needs. The woven slub silk has raindrops and spots on the surface, and the style is rough, simple and natural, and is deeply loved by consumers.

Slub silk, as the name suggests, is a fabric made of filament fibers after processing. Applicable filaments include chemical fiber filaments, silk (mulberry silk), milk silk, soybean silk and other natural filaments and other fine denier filaments. The slub silk processed by a special process is shiny and soft under dry conditions. Has smooth skin-friendly properties. When the twist changes (thick or slub length changes), compare the twist change with the slub spacing. The filaments suitable for slub silk include chemical fiber filaments, silk (mulberry silk), milk silk, soybean silk and other natural filaments and other fine denier filaments.

The processing technology of slub yarn can be divided into four types: twisting, air deformation, false twisting and untwisting (molecular recrystallization) drafting. Silk slub silk is made through a twisting process. The style characteristics of slub silk can accurately express the designer's design intention, and the thick knot and length are satisfactory. The disadvantage compared to the other two processes is that the production capacity is very low. Therefore, it is called art silk in the industry.

Air-textured slub is a kind of slub, which is blown into the slub by two or more filaments through a nozzle. Its style and variations are simple. The thickness and length of bamboo joints rarely vary. But the production capacity is large, so it is cheap.

False twisted slub yarn and untwisted (polymer recrystallized) slub yarn are produced on different elastic machines. Although two kinds of filaments are used as air-modified slub filaments, they differ in false twist machine false twist and filament heat drawn slub. The length and thickness of the bamboo joints do not vary much.

So two strands of silk slub/20tex is a classic slub.
