Processing Method of A Non-PVA Hollow Yarn and The Tubular Fabric

Abstract

The invention discloses the processing method of a non-PVA fiber hollow yarn and the tubular fabric. The fiber shall include filament yarn, staple yarn and ribbon. The processing method applies degradable fiber which is controllable in degradation conditions and has none formaldehyde residue to produce hollow yarn, in contrast with conventional soluble Vinylon hollow yarn, which is environmentally friendly and cheap while has low shrinkage and distinct hollow effect as can be made into high density textile and single yarn textile through sizing process. Furthermore, the tubular fabric as described in this invention spinned with the non-PVA fiber hollow yarn is feature with lightness, fluffy sense, warmth, moisture absorption and softness.

Description

BACKGROUND OF THE INVENTION[0001]The invention relates to the technology field of spinning, especially to the processing method of a non-PVA hollow yarn and the tubular fabric.[0002]Textile industry always creates good things to our life. The assortment and quality of yarn is the basis of quality of textile products. The basic assurance for enterprise survival, development and prosperity of textile markets is to output yarns of new varieties and good qualities as to meet and promote the quality of textile products and ultimately to bring the companies to be competitive in the market.[0003]Hollow yarn carries a special hollow structure which brings advantages of lightness and fluffy sense, warmth, moisture absorption, softness and so on as well as excellent usability of the product. With broad market prospects, it mainly applies for knitted underwear, high-class towel, socks, gloves and the other applications.[0004]Conventional hollow yarn is proceed with technology of covering yarn ...

AI Technical Summary

Benefits of technology

The invention is a method for processing a special type of fiber called degradable fiber, which can be controllably degraded and does not contain any harmful chemicals like formaldehyde. This fiber is used to make a hollow yarn, which is then used to create a lightweight, fluffy, warm, and moisture-absorbing fabric. This fabric is more comfortable and environmentally friendly than traditional fabrics made from water-soluble fiber. The key technical benefit is that the degradable fiber is processed under specific conditions to prevent shrinkage and ensure a flat fabric, making it suitable for high-density and single yarn textiles.

Problems solved by technology

However, there are a few issues as shown below for soluble Vinylon which has limited the popularity and development of hollow yarn.

However, there is no hollow effect eventually since the shrinkage of hollow area is distinct when the shrinkage ratio is high and the shrinkage is over performed; 4. Covering yarn with Vinylon cannot get into sizing process as result of the shrinkage and dissolution of soluble Vinylon fiber in hot water, thus, they are only suitable for low density or two fold textile.
