[0072] 1.2 Carding process:

[0073] For cleaning cotton: the gauge of the upper / lower cotton web cleaner before each gauge of the carding machine is 12-15‰ British silk / 12-15‰ British silk, and the gauge of the licker-in roller and dust removal knife is adjusted to 12-15‰ For ...

Embodiment 2

[0092] The present embodiment prepares blended yarn 2# and the spinning method difference of blended yarn 1# is:

[0093] The blending ratio of combed long-staple cotton / tussah silk in blended yarn 2# is 90% / 10%.

[0094] 1.2 Carding process: carding 20.5g / 5m

[0095] 1.4 Combing process

[0096] The combing process includes the following steps: the vehicle speed is 135 nips / min, the brush speed is controlled at 1000r / min, the draft gauge is 12mm, the noil gauge is 11.0mm, and the noil rate in the combing test is 16.30%;

[0097] Combed cotton quality: combed sliver weight 21.3g / 5m, noil rate 17.40%; ambient temperature / humidity 34°C / 59%;

[0098] 1.5 Mixing process

[0099] The pre-merged tussah silk sliver and the combed cotton fiber slivers are mixed for the second time, and the mixing conditions are controlled to obtain the mixed yarn; the ambient temperature / humidity is 31°C / 61%;

[0100] Mixed yarn: the mass ratio of CMC / tussah silk is 90% / 10%, and its fineness is 40...

Embodiment 3

[0110] The present embodiment prepares blended yarn 3# and the spinning method difference of blended yarn 1# is:

[0111] The blending ratio of combed long-staple cotton / tussah silk of blended yarn 3# is 50% / 50%.

[0112] 1.2 Carding process: the distance between the licker-in roller and the dedusting knife is adjusted to 15-18‰ British silk, and the carding is 20.5g / 5m.

[0113] 1.3 Combed cotton fiber pre-combed process: total draft / draft ratio of rear area 6.15 / 1.76.

[0114] 1.4 Combing process

[0115] The combing process includes the following steps: the vehicle speed is 135 nips / min, the brush speed is controlled at 1000r / min, the draft gauge is 12mm, the noil gauge is 11.0mm, and the noil rate in the combing test is 16.30%;

[0116] Combed cotton quality: combed sliver basis weight 19.0g / 5m, noil rate 17.40%; ambient temperature / humidity 33°C / 60%;

[0117] 1.5 Mixing process

[0118] The pre-merged tussah silk sliver and the combed cotton fiber slivers are mixed fo...

Abstract

The invention discloses a blended yarn of tussah silk and cotton fiber and a spinning method of the yarn and belongs to the field of spinning. The blended yarn is formed by blending the tussah silk with the cotton fiber, wherein the content of the tussah silk in the blended yarn is not higher than 60 wt%, and the balance is the cotton fiber; the fineness of the blended yarn is 20-120 S; single-yarn breaking strength of the blended yarn is 430-120 CN, and the size of neps is 5/50-150/480. The high-quality blended yarn fills up the market blank, is uniformed in component and evenness, high in single-yarn strength and low in hairiness and has few neps and yarn defects. According to the spinning method, combed cotton strips and tussah silk strips are directly subjected to mixed blending, the spinning flow is short, damage caused to the tussah silk is small, the utilization rate is high, the spinning cost is low, and the controlled blending ratio is accurate.

Description

technical field [0001] The invention relates to tussah silk and cotton fiber blended yarn and a spinning method thereof, belonging to the field of spinning. Background technique [0002] With the improvement of people's living standards and the change of the concept of textiles, people's demand for natural fiber textile products has increased, and new fibers with environmental protection, antibacterial, and deodorizing effects are favored by the market. [0003] Characteristics of tussah silk fiber: tussah silk belongs to protein fiber, besides the main silk fibroin, it also contains sericin, fat wax and natural pigments, etc. tussah silk feels soft and elastic, has good heat resistance, and is strong only when the temperature is as high as 140 ℃. Weakened, moisture resistance is also strong. Insulation, strength, elongation, anti-aging, acid resistance, and alkali resistance are all better than mulberry silk. However, the fabric shrinks greatly, and the raw silk is not ea...
