Description

Technical Field

[0001] The invention belongs to the field of textile preparation, and in particular relates to a preparation process of a water-absorbing and moisture-conducting colorful chenille carpet based on iterative polyester. Background Art

[0002] Chenille yarn is a spiral, rod-shaped, fluffy yarn made by twisting and clamping the cut velvet yarn. It is composed of core yarn and velvet yarn. Chenille yarn has excellent softness, fluffiness and lightness due to its unique structure, and its products have strong vitality in the market. In the twisting process of chenille yarn, the core wire moves forward by the rotation of the roller shaft and is twisted under the rotation of the spindle. In this process, it is subjected to great tension, so the core wire of chenille yarn is required to have a higher breaking strength.

[0003] Chenille textiles made of chenille yarn as the main raw material through weaving, dyeing, finishing, gluing and bottom coating, such as bathroom absorbent carpets, hallway vacuum mats, bedside mats, yoga mats, travel outdoor mats and other bathroom textile products, are mainly used for water absorption, vacuuming, anti-slip flooring, and decoration. They have developed rapidly in recent years. Conventional chenille carpets are mostly made of pure polyester with good mechanical properties, but pure polyester chenille fabrics have poor water absorption and moisture conduction effects. Water will remain on the surface of the carpet and cannot be absorbed and discharged in time, affecting the use of the carpet. Not only is it easy to slip, but the surrounding environment will produce a feeling of stuffiness and humidity, which can easily cause human discomfort. Summary of the invention
