High-dip-angle inside and outside reverse two-for-one twisting string and manufacturing method thereof

Abstract

The invention discloses a high-dip-angle inside and outside reverse two-for-one twisting string for a Chinese zither and a plucked stringed instrument and a manufacturing method of the high-dip-angleinside and outside reverse two-for-one twisting string. The string comprises an axis line and a plurality of coating layers; the coating layers surround the axis line and are mutually stacked in the radial direction of the axis line; each coating layer comprises a plurality of coating lines, and the coating lines are mutually attached and jointly wound on the adjacent coating layers on the inner side or the axis line; all the coating lines are inclined by 10-30 degrees relative to the axis line; and the inclined directions of the coating lines of any two adjacent coating layers are opposite. The high-dip-angle inside and outside reverse two-for-one twisting string is made of a composite man-made medium, so thatno life is harmed;by means of a high-dip-angle inside and outside reverse two-for-one twisting disc method, the string has high stability, string tuning is almost not needed, the string is not susceptible to the air temperature and humidity, the surface is meticulous, and the hand-pressing tone is retained;and when the string is tensioned, the situation that the coating line on the outermost layer of the string is prone to opening to generate a gap, and consequently the fingers are cut is avoided.

Description

technical field [0001] The present invention relates to a string and its manufacturing method, especially to a string used for guqin and its manufacturing method. Background technique [0002] Guqin is a Chinese plucked stringed instrument with a wide range and deep tone. Since ancient times, it has been a must-have knowledge and compulsory subject for many literati. see Figure 6 and Figure 7 As shown, the strings used in Guqin since ancient times are silk strings 90, which are made of silk, which is made in a way that the inner layer is multi-strand coiled and the outer layer 91 is single-strand straight. Because of the material and manufacturing method, the silk string 90 has a warm and ancient tone and a unique hand tone, so it is loved by the majority of classical musicians. But the silk string 90 is susceptible to the impact of climate and humidity and is relatively unstable. It will go out of tune during the performance and needs to be tuned from time to time; The...

AI Technical Summary

Problems solved by technology

However, although steel strings overcome the shortcomings of silk strings, they also lose their warm and ancient timbre and unique hand tone, which makes the overall performance different from the previous guqin, so that they are not loved by classical musicians.

[0004] Therefore, the strings in the prior art really need to be improved.
