Embodiment 1
[0040] A kind of preparation method of core-spun tape yarn, it comprises following preparation steps:
[0041] Step 1. Use a multifunctional spinning prototype to twist non-water-soluble roving and water-soluble vinylon single yarn into core yarn;
[0042] Step 2: Weave the yarn into a tubular mesh leather yarn with a small needle cylinder loom equipped with a fancy twister, and then feed the core yarn directly into the inner cavity of the needle cylinder so that the core yarn is placed in the leather yarn and covered with the leather yarn Wrapped, got tape yarn;
[0043] Step 3. Soak the tape yarn in an aqueous solution at 75°C, so that the vinylon single yarn of the tape yarn is dissolved by the aqueous solution until the weight loss rate of the yarn is close to equilibrium, and the fiber removal is completed, and then the finished product is dried to obtain a core-spun tape yarn .
[0044] Wherein, the fineness of the roving is less than 20S, the fineness of the vinylon s...

[0055] A kind of preparation method of core-spun tape yarn, it comprises following preparation steps:
[0056] Step 1. Use a multifunctional spinning prototype to twist non-water-soluble roving and water-soluble vinylon single yarn into core yarn;
[0057] Step 2: Weave the yarn into a tubular mesh leather yarn with a small needle cylinder loom equipped with a fancy twister, and then feed the core yarn directly into the inner cavity of the needle cylinder so that the core yarn is placed in the leather yarn and covered with the leather yarn Wrapped, got tape yarn;
[0058] Step 3. Soak the tape yarn in an aqueous solution at 70°C, so that the vinylon single yarn of the tape yarn is dissolved by the aqueous solution until the weight loss rate of the yarn is close to equilibrium, and the fiber removal is completed, and then the finished product is dried to obtain a core-spun tape yarn .

Embodiment 3
[0065] A kind of preparation method of core-spun tape yarn, it comprises following preparation steps:
[0066] Step 1. Use a multifunctional spinning prototype to twist non-water-soluble roving and water-soluble vinylon single yarn into core yarn;
[0067] Step 2: Weave the yarn into a tubular mesh leather yarn with a small needle cylinder loom equipped with a fancy twister, and then feed the core yarn directly into the inner cavity of the needle cylinder so that the core yarn is placed in the leather yarn and covered with the leather yarn Wrapped, got tape yarn;
[0068] Step 3. Soak the tape yarn in an aqueous solution at 80°C, so that the vinylon single yarn of the tape yarn is dissolved by the aqueous solution until the weight loss rate of the yarn is close to equilibrium, and the fiber removal is completed, and then the finished product is dried to obtain a core-spun tape yarn .
[0069] Wherein, the fineness of the roving is less than 20S, the fineness of the vinylon s...
