Embodiment Construction

[0020] A musical instrument string, the material of which comprises 97-99.9% of polybutylene terephthalate (PBT nylon) and 0.1-3% of calcium carbonate by weight percentage. Such as polybutylene terephthalate 99.9%, calcium carbonate 0.1; or polybutylene terephthalate 97%, calcium carbonate 3%; or polybutylene terephthalate 98%, calcium carbonate 2%. The musical instrument string of the modified material can be applied to strings of instruments such as Ukulele, classical guitar and folk music, especially as treble strings.

[0021] The preparation method of the musical instrument string comprises the following steps:

[0022] (1) Pour polybutylene terephthalate into the extruder in proportion to plasticize;

[0023] (2) During the hot-melt process of polybutylene terephthalate, calcium carbonate is added in proportion to increase the binding force between molecules;

[0024] (3) The screw of the extruder heats polybutylene terephthalate and calcium carbonate to a colloidal s...

Abstract

A string for musical instruments is made of a material prepared from, by weight, 97-99.9% of polybutylene terephthalate and 0.1-3% of calcium carbonate. By addition of the calcium carbonate for modification of PBT (polybutylene terephthalate), an internal molecular structure and an internal stress of production creeping are changed, and accordingly material stability and creep resistance are improved, and defects of long tone setting time and quick tone altering of strings made of traditional nylon materials are overcome. The novel special material, made of the modified PBT nylon, of the string for the musical instruments has advantages of high strength, fracture resistance, low extensibility, dimensional stability and durable balance and uniformity of timbre and pitch of the string for the musical instruments in use due to prevention of water absorption.

Description

technical field [0001] The invention relates to a musical instrument, in particular to a musical instrument string using modified PBT nylon as a material. Background technique [0002] At present, nylon strings are widely used in musical instruments. After adjusting the pitch on the musical instrument, the sound will change and relax after a period of time, and the strings must be re-adjusted or replaced. High elasticity, low tensile strength, high creep, and high moisture absorption. This property also causes problems such as insufficient sustain and fullness during playing, low frequency is not bright enough, and mid-high frequency is not full and solid enough. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a modified material and musical instrument strings, which can overcome the problems that the nylon strings have large creep and low tensile strength during the use of musical instruments, resulting in voice...
