The birth and development of optical fiber communication is an important revolution in the history of telecommunication, and the optical fiber communication changes the traditional communication mode, so that the communication with high speed and large capacity becomes possible without being interfered by various kinds of magnetism. With the continuous development of optical fiber cables and communication technologies, the optical fiber communication technology has also been improved greatly. At present, the optical fiber cable becomes an important material basis of modern communication at a rapid speed and in a wide application range, and the influence on social life is deeper and deeper.
In order to adapt to different use environments, the optical cable is generally designed by adding corresponding reinforcing members or changing the structure of the optical cable according to the environmental characteristics. The optical cable reinforcement can be divided into a metal reinforcement and a nonmetal reinforcement, the main metal reinforcement comprises steel wires, aluminum strips and the like with different sizes, and the nonmetal reinforcement mainly comprises FRP (fiber reinforced plastics), KFRP (KFRP), a water-blocking tape, aramid fibers, a binding yarn, a glass fiber yarn and the like. The metal reinforcing part is mainly used in construction and use environments with high requirements on axial tension due to high hardness and strength, such as outdoor overhead laying, pipelines, direct burial and the like. The non-metallic reinforcement members have different functions due to their various kinds. Because the nonmetal reinforcing part is relatively soft and the tensile property is smaller than that of the metal reinforcing part, the nonmetal reinforcing part can be applied to occasions such as indoor places, corridors, floors and the like, or can be attached to the metal reinforcing part for use when special requirements exist. For some special environments, such as environments with frequent rat damage, special reinforcements are needed to meet the requirements of axial and transverse stress and bite resistance required by the special reinforcements. The glass fiber yarn is non-toxic, harmless, non-combustible, high-temperature-resistant, corrosion-resistant, stable in chemical property, better in wear resistance and insulativity and suitable for the optical cable reinforcement.
The glass yarn is also called as glass fiber yarn, is an inorganic non-metallic material with excellent performance, and has excellent tensile property, electric insulation property, high temperature resistance and corrosion resistance. The non-metallic reinforcing member is widely used in the optical cable industry at present. But the glass yarn has poor wear resistance and is relatively brittle, and in order to improve the performance of glass yarn products, the existing glass yarn products use water-soluble sizing agents; however, the moisture is dried in the processing process, and because the moisture content is about 90%, a large amount of moisture needs to be dried, so that the production efficiency is very low.

Wherein, cold air blows under the glass yarn and over the glass yarn, quickens the cooling speed.
Performance testing
Measuring the density by a pycnometer method:
taking 3g of a proper amount of glass yarn coating material;
weighing the mass of a clean pycnometer in an environment with the temperature of 23 +/-2 ℃, the humidity of 50 +/-10 percent RH and the atmospheric pressure of 70 kPa-106 kPa, and recording the mass as mBottle (Ref. TM. bottle)(ii) a Taking the mass of the glass yarn coating material and recording the mass as mSample (A)(ii) a Filling absolute ethyl alcohol into the pycnometer, slowly plugging the bottle mouth with a grindstone glass plug with capillary tube to make the excessive absolute ethyl alcohol overflow from the capillary tube, wiping off the absolute ethyl alcohol on the outer wall of the pycnometer, weighing its mass, and recording it as mBottle + liquid(ii) a Placing weighed glass yarn coating material sample into a pycnometer filled with anhydrous alcohol, slowly plugging the bottle mouth with a grindstone glass plug with capillary to make excessive anhydrous alcohol overflow from the capillary, wiping off anhydrous alcohol on the outer wall of the pycnometer, weighing its mass, and recording as mBottle + liquid + sample. Query for density ρ of absolute ethanolLiquid for treating urinary tract infection. According to the formula: rhoSample (A)=mSample (A)*ρLiquid for treating urinary tract infection/(mBottle + liquid+mSample (A)-mBottle + liquid + sample) The density of the glass yarn coating material is obtained, and specific data are shown in the following table 3.
TABLE 3 Density data for examples 1-6 and comparative examples 1-4
As can be seen from the above table, the densities of the glass yarn coatings of examples 1-6 were not greater than 1.01g/cm3In particular, the density of examples 1 to 2 and examples 4 to 5 was less than 1, and that of example 6 was only 0.85g/cm3Therefore, more coating materials can be coated on the glass yarns in the later period, the weight of the glass yarns is not influenced too much, and the market needs are better met.
The density of comparative example 1 is relatively high, and the amount of the coating material for glass yarn is reduced to meet the requirement, and the performance of the glass yarn is also affected to a certain extent. The densities of comparative examples 2-4 were satisfactory, but other properties were to be improved.
Testing the density of the glass yarn:
taking a glass yarn sample with the length of 10m by using a precision roller, wherein the length is recorded as L, weighing the glass yarn sample on a balance, and the mass is recorded as m;
the glass yarn density LD = (1000 × m)/L was obtained according to the formula.
With 6 examples and 4 comparative glass yarn coating slips, 1200tex glass yarn samples were prepared for use examples 1-6 and use comparative examples 1-4, with the linear densities for use examples 1-6 and use comparative examples 1-4 being shown in table 4 below.
TABLE 4 Linear Density for application examples 1-6 and for application comparative examples 1-4
The standard range of error of 1200tex glass yarn is required to be within +/-5%, application examples 1-6 can meet the requirement, application comparative examples 1-4 can also meet the requirement, but the density error of the commercially available glass yarn exceeds the standard range requirement, the weight of the glass yarn is influenced, and the specification and the quality of the cable are possibly influenced. Combining tables 3 and 4, the density of example 3 was relatively high, and the linear density of application example 3 was also relatively high. It can be seen that although the densities of example 5 and example 6 are relatively small, the amount of glue applied is larger than those of examples 1 and 2 because sufficient adhesive property is secured, and thus the linear density of application example 1 is equal to that of application example 6, and the linear density of application example 2 is smaller than that of application example 5. The density of the same example 4 was lower than that of example 1, but the linear density of application example 4 was higher because the coating amount was a little more. Application comparative examples 1 to 4 were satisfactory in terms of linear density, but other properties were to be improved.
Testing the mechanical properties of the glass yarns by a drawing machine:
the tests were carried out according to the standard YD/T1181.4-2015 for the corresponding examples 1-6 and for the corresponding comparative examples 1-4, for the commercially available glass yarns; specific test data are shown in table 5.
TABLE 5 mechanical Property test data for commercially available glass yarns using examples 1-6 and using comparative examples 1-4
Referring to table 5, it can be clearly found that the tensile strength of the application examples 1-6GPa is above 680N when the linear density (or the coating amount) of the glass yarn is close, compared with the tensile strength of the application comparative examples 1-4 at 633-652N, the tensile strength of the commercially available glass yarn is 653N. Meanwhile, the constant elongation force corresponding to the elongation, namely FASE-0.3%, FASE-0.5% and FASE-1.0%, is also obviously improved, the FASE-0.3% values of application examples 1-6 are all over 96N, the FASE-0.3% value range of application examples comparative examples 1-4 is obviously reduced to 82-85N, and the FASE-0.3% value of commercially available glass yarns is only 87N; the FASE-0.5% values of application examples 1-6 were all above 168N, the FASE-0.5% value range of application examples comparative examples 1-4 was significantly reduced to 153-157N, and the FASE-0.5% value of commercially available glass yarns was only 1656N; the FASE-1.0% values of the application examples 1-6 were all above 352N, the FASE-1.0% values of the application examples comparative examples 1-4 were significantly reduced to 301-310N, and the FASE-1.0% value of the commercially available glass yarns was also only 322N. The elongation at break of the application examples 1 to 6 was approximately equivalent to that of the commercial products, and the elongation at break was also equivalent to that of the comparative examples 1, 3 and 4. The Young's modulus of the application examples 1-6 is far more than that of the commercial products and the application comparative examples 1-4, the Young's modulus of the application examples 1-6 is in the range of 74-76 GPa, the Young's modulus of the application comparative examples 1-4 is only in the range of 64-67 GPa, and the Young's modulus of the commercially available glass yarns is also only 68 GPa. This also demonstrates that the glass yarns produced according to the invention have excellent resistance to deformation.
From the analysis of table 5, we can clearly see that the mechanical properties of the glass yarns prepared according to the invention are significantly higher than those of the comparative examples, indicating that the formulation and preparation of the coating has a very large influence on the properties of the final glass yarn product. The mechanical properties of the glass yarns prepared in application examples 1-6 also significantly exceeded those of the commercially available glass yarn products, compared to the commercially available glass yarn products.
Through the comparison, the invention has stronger competitiveness for some client products with high standards and high requirements on indexes.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
