Problems solved by technology

[0002] The spinnability of natural colored cotton is gradually improved after transformation, and is close to the index of ordinary cotton, but there is a gap between natural colored cotton fiber and ordinary cotton fiber, such as finer fiber fineness, poor maturity, low fiber strength, and longer fiber length. Short, short staple rate, high nep impurities, etc., can only produce coarse-count products, which not only affects the spinning process of the fiber, but also affects the specific process of the sizing process due to the spinning performance, so it needs to be targeted The quality of sizing can only be guaranteed if the sizing process is adapted to it

preparation example Construction

[0008] The preparation method of the present invention is the following steps:

[0009] The unwinding tension during sizing is 300-350N, and at the same time, ensure reliable braking when the sizing machine stops. The tension of the size tank is 300-360N, and the temperature of the size tank is not higher than 90±3℃. Dip four pressures to reduce the coverage factor of the sizing yarn in the size tank to enhance penetration, control the depth of immersion at 20cm, the viscosity of the size tank is about 9s, and appropriately increase the pressure of the front pressure roller, the pressure of the front pressure roller is 6.5-8.0KN, and the pressure of the back pressure Stick pressure 6.0-16.0KN, can increase side pressure twice, side pressure pressure 3.0-4.0KN, re-coating under the premise of ensuring a certain penetration, use wet twisting stick to make the hairiness of the yarn further stick when it enters the drying area Coating, enhance the grip and control of the size film...

Embodiment 1

[0012] Ingredients: natural colored cotton yarn such as 40s yarn, the number of warp yarns is 6751;

Embodiment 2

[0016] Ingredients: natural colored cotton yarn such as 40s yarn, the number of warp yarns is 6751, the preparation method is the same as that of Example 1, the difference is that it adopts double dipping and double pressing, and the pressure of the front pressing bar is 8.0KN.

[0017] In summary, after sizing in the sizing process of the present invention, the sizing rate of the yarn reaches 7.5 ± 0.5%, the sizing hairiness fits and the yarn strength is significantly improved, and the efficiency of the loom is above 96.4%, which improves the production value of the product .

Abstract

The invention provides a novel concept of natural colored cotton sizing and a method thereof. When the natural colored cotton is clear-starched, penetration of serous fluid to the yarn is improved; after the yarn enters a drying area, the holding and control of a serous film to the yarn is enhanced; unwinding tension is properly enhanced, and the coverage of serous material to the yarn is improved so as to lead the weaving efficiency of the yarn on a weaving machine to be greatly improved; few broken ends exist during the clear-starching process; sizing junk can meet requirement; clear-starching rate of the yarn is as high as 7.5 percent plus or minus 0.5 percent; sizing hairs adhesiveness and the strength of the yarn are improved obviously; the efficiency of the weaving machine is over 96.4 percent and the production value of the product is increased.

Description

technical field [0001] The invention relates to a sizing process for warp yarn sizing, in particular to a sizing process for warp yarn sizing with natural colored cotton. Background technique [0002] The spinnability of natural colored cotton is gradually improved after transformation, and is close to the index of ordinary cotton, but there is a gap between natural colored cotton fiber and ordinary cotton fiber, such as finer fiber fineness, poor maturity, low fiber strength, and longer fiber length. Short, short staple rate, high nep impurities, etc., can only produce coarse-count products, which not only affects the spinning process of the fiber, but also affects the specific process of the sizing process due to the spinning performance, so it needs to be targeted The quality of sizing can only be guaranteed if the advanced sizing process is adapted to it. Contents of the invention [0003] The purpose of the present invention is to provide a kind of natural colored co...
