Functional fiber bulked yarn fabric blanket and making method thereof

Abstract

The invention relates to a making method of a functional fiber bulked yarn fabric blanket. The making method comprises the steps that continuous functional fiber endless tows are continuously blown and sprayed through high-speed air flow to be in the screw type bulked state, and functional fiber bulked yarns and the endless tows made of the same raw materials as the functional fiber bulked yarns are merged in an over-feed mode to form bulked composite yarns; the bulked composite yarns are used as weft yarns to be interwoven with the endless tows to form the fabric blanket, and thick fiber blankets with various standards can be formed by weaving. The continuous functional bulked yarn blanket not only maintains the advantages of chopped fiber blankets, but also adds new functions, defects of short fiber punched felts are overcome, and the whole mechanical property of a fiber net is improved. The functional fiber bulked yarn fabric blanket can be directly applied to materials for thermal insulation, filtering, adsorption, abrasion and the like, can also be used as fiber prefabricated bodies for composite materials, gives full play for mechanics bearing performance and functionality advantages, and has wide application prospects.

Description

technical field [0001] The invention relates to a continuous functional fiber bulky yarn fabric blanket, in particular to a bulky yarn fabric blanket woven by using continuous functional fiber bulky yarn and bulky composite yarn. It not only has the characteristics of bulky and porous non-woven fabrics, but also has the basic structure of woven fabrics. Can be used for thermal insulation blankets or as fiber preforms for composite materials. Background technique [0002] The continuous functional fiber bulked yarn fabric blanket is a thermal insulation material or fiber prefabricated body that can give full play to the characteristics of long fibers. It has both the performance of chopped fiber webs and the structural designability of long fiber products. [0003] Hangzhou Xiaoshan Tiancheng Machinery Co., Ltd. produces and provides glass fiber bulked yarn machine equipment for the production of bulked yarn. The high-speed air flow expander is a key part of the equipment. ...

AI Technical Summary

Problems solved by technology

[0005] Chopped fiber web felting has the following disadvantages: (1) The damage to the fiber is relatively large during the carding process; (2) the single fiber in the fiber web cannot be completely straightened; (3) the uniformity and quality consistency of the web are very poor Difficult to control; (4) The direction of the fiber cannot be designed, and the mechanical properties of the fiber web are not good; (5) The interlayer performance of the chopped fiber mat is very poor; (6) It is prone to loose or rotten edges

Due to the rigidity, brittleness and poor cohesion of carbon fibers, it is difficult to comb chopped carbon fibers

In addition, there will often be fiber winding around the roll, making it difficult to transfer, resulting in the failure to go out of the net normally.
