Problems solved by technology

In these several manufacturing methods, after the non-woven fabric is hot-rolled, the surface is melted into a paper-like smooth surface to achieve the water-blocking effect. The thickness of the belt is increased, and the weight is increased, which increases the cost of the cable and optical cable

Abstract

The invention discloses an ultra-thin non-woven fabric for cable and optical cable expansion water-blocking tape and a production method of the ultra-thin non-woven fabric. The ultra-thin non-woven fabric comprises a polyester fiber layer, through holes and a hydrophilic water absorbing expansion material. The upper surface and the lower surface of the polyester fiber layer are each provided withthe through holes. The hydrophilic water absorbing expansion material is arranged in the polyester fiber layer and on the upper surface and the lower surface of the polyester fiber layer. The ultra-thin non-woven fabric for the cable and optical cable expansion water-blocking tape is prepared by conducting opening, carding, lapping, carding again, hot rolling, puncturing, coiling and material soaking through a non-woven device. In this way, a cable rapidly expands when the cable encounters water and tidal gas enters the cable so that water can be prevented from entering, the safety effect is achieved, and the cost of a package material of the cable and the optical cable is greatly reduced.

Description

technical field [0001] The invention relates to the field of fabrics, in particular to an ultra-thin non-woven fabric for expansion water-blocking tapes of cables and optical cables and a production method thereof. Background technique [0002] Non-woven fabrics are widely used due to their short process flow, fast production speed, high output, and low cost. The water-blocking belts in optical cables are also made of non-woven fabrics as base fabrics and water-absorbing swelling materials. Optical cable is an indispensable means of transportation in urban power and communication lines, but it is subjected to mechanical pressure from the foreign office during the laying or maintenance process, which sometimes causes water and moisture to enter. Water and moisture invade the interior of the cable, which will cause Disconnection, insulation degradation. In order to ensure the safe operation of optical cables and prolong their service life, various researches and developments ...
