Embodiment 1

[0029] The present invention relates to a seam-bonded nonwoven fabric for electrical tape base fabric, which comprises 50 wt% of polyester staple fibers with a fiber fineness of 1.4D and a length of 51 mm and 50 wt% of polyester staple fibers with a fiber fineness of 2D and a length of 51 mm After the mixed fiber is used as the raw material to make the fiber web, the active warping method is used to reinforce the sutures with 75D / 72F fine denier polyester DTY filaments that have undergone a specific warping method. Then it is made by hot rolling process.

[0030] It should be noted that the polyester staple fiber with a specific fineness involved in the present invention is a polyester staple fiber with a fineness of 1.4D-15D, wherein the polyester staple fiber with a fineness of 1.4-2D and a length of 32-51mm and a fineness of 2D-2.5D and a length of The total content of polyester staple fibers with a size of 51-102mm is not less than 70%, and the content of polyester staple ...

Embodiment 2

[0039] The present invention relates to a seam-bonded nonwoven fabric for electrical tape base fabric, comprising 50wt% polyester staple fibers with a fiber fineness of 1.4D and a length of 51mm and 30wt% polyester staple fibers with a fiber fineness of 2D and a length of 51mm And 20wt% fiber fineness of 6D, length of 51mm polyester staple fiber mixed fiber as raw material to make fiber web, adopt the way of active warping, with 75D / 72F fine denier polyester DTY filament through specific warping method Reinforced sutures are stitched and reinforced on a stitch-bonding machine with adjusted technology and then made by hot rolling.

[0040] This embodiment also provides a method for preparing a seam-bonded nonwoven fabric for electrical tape base fabrics. After opening and carding polyester staple fibers of a specific denier, they are laminated to form a fiber web with a specific single-layer grammage. The warp let-off method uses fine-denier polyester filaments that have underg...

Embodiment 3

[0048] The present invention relates to a seam-bonded nonwoven fabric for electrical tape base cloth, with 40wt% polyester staple fibers with a fiber fineness of 2D and a length of 51mm and 40wt% fiber fineness of 2.5D, a length of 51mm and 20wt% fibers The mixed fiber of polyester staple fiber with a fineness of 15D and a length of 102mm is used as a raw material to make a fiber web, and the warp is actively let off, and the suture is reinforced with 75D / 72F fine denier polyester DTY filament after a specific warping method. It is stitched and strengthened on a stitch-bonding machine adjusted by the process, and then made by a hot-rolling process.

[0049] This embodiment also provides a method for preparing a seam-bonded nonwoven fabric for electrical tape base fabrics. After opening and carding polyester staple fibers of a specific denier, they are laminated to form a fiber web with a specific single-layer grammage. The warp let-off method uses fine-denier polyester filamen...

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...
