Stitch knitting non-weaving cloth for electrical tape base cloth and production method thereof

Abstract

The invention discloses stitch knitting non-weaving cloth for electrical tape base cloth and a production method thereof. The production method comprises the following steps of: oploosening and carding polyester staple fibers with specified fineness and paving and laminating the carded polyester staple fibers to form a fiber web with specified monomer gram weight; reinforcing stitches with fine denier polyester filaments formed by a specified warping mode by adopting an active warp let-off mode; and carrying out stitching knitting and reinforcing on a stitch knitting machine adjusted by a process and then carrying out hot pressing to form the stitch knitting non-weaving cloth. Compared with a general product, the stitch knitting non-weaving cloth produced by adopting the production method disclosed by the invention has the characteristics that transverse breaking strength is great so as to facilitate the next coating processing of the product; longitudinal tearing strength is small so as to ensure the advantage of convenience for tearing with hand in actual application of next terminal product; the service performance of products is greatly improved; and the stitch knitting non-weaving cloth can be widely applied to base cloth of electrical tapes and the like of various cables and electronic elements and has wide popularization significance.

Description

technical field [0001] The invention relates to the field of nonwoven stitch-bonding applications, in particular to a stitch-bonded nonwoven fabric for electrical tape base cloth and a preparation method thereof. Background technique [0002] As we all know, in recent years, the application range of non-woven fabrics has become more and more extensive. With the continuous improvement of the technical level, non-woven fabric products have gradually appeared in all aspects of social life. In the fields of industry, agriculture, sanitation, and medical treatment, nonwoven fabrics are more and more favored by people because of their simple process, high production efficiency, low cost, and stable and reliable quality. For non-woven products, there has been a wave of research and development boom at home and abroad in recent years, and a large number of patent documents on the progress of non-woven products and technology research have emerged. [0003] For example, the patent 2...

Problems solved by technology

[0004] Another example is patent 200810178856.2 "Noise Suppression and Highly Wear-Resistant Tape" which emphasizes the structure of tapes that can be used to wrap wires or cable bundles, but how to achieve low longitudinal and transverse tearing strength is not yet clear for the carrier nonwoven fabric that is an important part of the tape. put forward a clear plan

[0005] Another example is the patented CN1033453 "New Composite Packaging Material" which discloses a composite of nonwovens and yarns (or synthetic flat filaments), which can be used to make packaging bags for cement, chemical fertilizers, powdery chemical raw materials and products, and is not suitable for electric wires. , cables and other packaging tapes
