Detailed Description

In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings.

The invention provides a fine denier terylene, antibacterial terylene and cotton three-component super-soft antibacterial yarn, which comprises 30 percent of fine denier terylene fiber, 20 percent of antibacterial terylene fiber and 50 percent of cotton fiber by weight percent, and the fibers are made into 14.8tex (40S) blended yarn by a blending process.

The manufacturing method comprises the following steps:

s1, selecting raw materials: the type of the fine denier polyester fiber is 0.89dtex multiplied by 38mm, and the type of the antibacterial polyester fiber is 1.56dtex multiplied by 38 mm;

s2, raw material pretreatment: uniformly discharging the antibacterial polyester fiber and the fine denier polyester fiber in a disc according to the weight average of the package, wherein the heights are parallel and level; the mixing proportion is that the fine denier terylene accounts for 60 percent and the antibacterial terylene accounts for 40 percent;

s3, blowing process: fully mixing the antibacterial polyester fiber and the fine denier polyester through a multi-bin cotton mixer and then forming strips;

s4, drawing:

the method sequentially comprises the following steps: the prepared mixed cotton carding strips containing the two terylene fibers are pre-combined in one step, and 8 cotton carding strips are combined to prepare pre-drawing strips; the pre-drawing quantitative is 3.6 g/m; mixing the polyester pre-drawing strips and the pure cotton combed strips, wherein the dry weight of the pure cotton combed strips is 3.6g/m, the polyester pre-drawing strips are 4, and the pure cotton combed strips are 4; the pre-drawing is mixed by three times, so that the mixing effect is further ensured;

s5, roving; designing the twist quantity of the roving to be 520 g/m; the roving twist factor is 89; the roving spindle speed is 850 revolutions per minute; the surface gauge of the rear area of the roving is 35mm, and the drafting multiple of the rear area is 1.17;

s6, spinning step: as shown in FIG. 1, a single-wheel rotor 3 false twisting method is adopted; after the roving is drafted, after the roving is output by a jaw formed by a front rubber roller 1 and a front roller 2, the roving passes through a tangent plane of a single-wheel-disc rotating wheel 3 with a set matching speed, a spinning section is operated on the tangent plane of the single-wheel-disc rotating wheel 3 to obtain true twist generated by the false twisting action of the single-wheel-disc rotating wheel 3, and then the roving is operated through a yarn guide ceramic 4, a steel wire coil 5 and a steel collar 6 to form low twist yarn.

In the raw material selection process, the adopted antibacterial polyester fiber is added with components with antibacterial property in the production process of the polyester fiber, and the fiber has permanent antibacterial property;

wherein, in the blowing-carding process, the linear speed ratio of the adopted large cylinder licker-in is 2.3;

in the drawing process, the three mixing steps of pre-drawing adopt a forward drafting process, and the back zone drafting multiples of the first mixing step, the second mixing step and the third mixing step are respectively 1.75, 1.68 and 1.65; controlling the distance of the pre-drawing strip to be larger, wherein the distance of the main drawing surface is 12mm, and the distance of the back zone surface is 19 mm;

in the spinning process, the single-wheel disk rotating wheel is positioned between the jaw of the spinning front roller and the yarn guide ceramic, and due to the false twisting effect of the single-wheel disk rotating wheel, the strength of a region where yarn breakage is most likely to occur is obviously improved, so that yarn breakage is not easily caused in a spinning section, and normal spinning at low twist can be guaranteed.

In the spinning process, by adopting the false twisting method of the single-wheel disc rotating wheel, the yarn is ensured not to be easily broken under the condition that the spinning twist coefficient is designed to be small, and the soft and fluffy effect of the yarn can be achieved; the twist between the single-wheel disk rotating wheel and the ceramic ware is obviously reduced, and because the twist is low, the yarn is soft and fluffy, and the antibacterial effect is obvious and has an ultra-soft effect.

The yarn quality index of the blended yarn is as follows:

14.8tex (40S) of blended yarn, 13.4 percent of yarn evenness variation coefficient, 2/km of detail, 11 slubs/km, 23 neps/km and 1.8 percent of weight variation coefficient; the breaking strength of single yarn is 20.3cN/tex, and the variation coefficient of single yarn strength is 11.1%; hairiness is reduced by 8% compared with the conventional spindle changing spinning.

The specific working principle of the invention is as follows:

in the spinning process, in order to achieve the soft and fluffy effect of the yarn, the spinning twist coefficient is designed to be small, the yarn is easy to break in the spinning process, and the normal production is difficult to ensure; after the roving is drafted, after the roving is output from a jaw formed by a front rubber roller and a front roller, through a single-wheel disc rotating wheel tangent plane with set matching speed, a spinning section is obtained by the true twist generated by the false twist action of the single-wheel disc rotating wheel when the roving runs on the single-wheel disc rotating wheel tangent plane, the single-wheel disc rotating wheel is positioned between the jaw of the spinning roller and a yarn guide ceramic device, the strength of the area where the breakage is most likely to occur is obviously improved, and therefore the breakage is not easily caused in the spinning section; the twist between the single-wheel disc rotating wheel and the yarn guide ceramic is obviously reduced, and then the low twist yarn is formed by running through a steel collar steel wire coil and the like; because the twist is low, the yarn is soft and fluffy, and has an ultra-soft effect and an obvious antibacterial effect.

The foregoing is illustrative of the best mode of the invention and details not described herein are within the common general knowledge of a person of ordinary skill in the art. The scope of the present invention is defined by the appended claims, and any equivalent modifications based on the technical teaching of the present invention are also within the scope of the present invention.
