Novel PP ultrathin thermal insulation shell fabric and production method thereof

Abstract

The invention discloses a novel PP ultrathin thermal insulation shell fabric and a production method thereof. The production method comprises the steps that firstly, 75D or 8.3tex ultrafine-denier PP and novel 42D XLA comfortable and elastic fibers are interwoven; secondly, shaping and longitudinal and transverse drawing are performed at the temperature between 120 DEG C and 130 DEG C; thirdly, the dyeing and finishing process is performed; fourthly, processing and aftertreatment are performed. The shell fabric produced through the method is high in dimensional stability and heat loss and light and thin in texture, has the functions of keeping warm, being breathable, carrying anions and so on, is light and thin, soft in handfeel, good in fluffing and pilling resistance and light, attractive and comfortable to wear, can free people from past bloat in winter and achieves perfect combination of science and technology, fashion and functions, and the shrinkage rate is less than 2%.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a novel PP ultra-thin thermal insulation fabric and a production method thereof. Background technique [0002] With the progress of the times, people have put forward more and more requirements for underwear. Consumers hope that thermal underwear has the characteristics of warmth retention, health care, antibacterial, mildew resistance, breathability, moisture conduction, lightness, softness, close fit, comfort and beauty. , which poses a new challenge to thermal underwear in winter. Thermal underwear that is both light and warm has strong consumer demand and broad market prospects. [0003] The winter thermal underwear currently on the market is mainly made of polyester flannelette and cotton, followed by cashmere, wool, silk, vinylon, polypropylene and other materials. However, polyester and cotton thermal fabrics are mostly heavy and bloated, which cannot meet people’s aesth...

AI Technical Summary

Problems solved by technology

However, polyester and cotton thermal fabrics are mostly heavy and bloated, which cannot meet people’s aesthetic requirements; cashmere has excellent thermal performance, but is too expensive, and the quantity is limited; silk has good thermal performance, but it is too expensive and too little; wool thermal performance is good, However, it is easy to feel itchy when worn next to the body, the price is also expensive, and the quantity is limited; vinylon is not water-resistant and cannot be made into practical fabrics; polypropylene has the best thermal performance, but traditional polypropylene can only withstand temperatures below 130°C, and the dimensional stability of fabrics is a big problem
