Embodiment 1

[0027] Increase length at 27~33 millimeters, the flax fiber that fineness is about 1200 (Nm) carries out fiber mixing together as intermediate fiber with jute fiber and cotton fiber. The fineness metric count (Nm) of the flax fiber is 2.4~3 times of the fineness metric count (Nm) of the jute fiber, and the fineness metric count (Nm) of the cotton fiber is 2.4~3 times of the flax fiber fineness metric count (Nm). About 5 times that of fiber, according to figure 2 and image 3 As shown, at this time, because the fineness difference between flax fiber, jute fiber and cotton fiber is not large, it can be entangled with jute fiber and cotton fiber in blending. The breaking strength of jute / cotton / flax blended 12 counts (s) yarns of different blending ratios is shown in the table below:

[0028] Table 2 Breaking strength of jute / cotton / flax blended yarn with 12 counts (s)

Embodiment 2

[0033] In order to enhance the breaking strength of jute and cotton fiber blended yarn, it is also possible to add polyester fibers with a length of 27 to 33 mm and a fineness of 2000 to 4500 (Nm) into the jute and cotton fibers for fiber mixing. The breaking strength of 12 yarns of blended jute / cotton / polyester fiber blended in percentage by weight is shown in the table below.

[0035] Proportion (wt%) Breaking strength (cN) 20 / 65 / 15 592.87 25 / 50 / 25 647.56 30 / 50 / 20 618.93 30 / 40 / 30 655.79 40 / 45 / 15 587.65 45 / 50 / 5 545.98 50 / 28 / 22 590.45 60 / 30 / 10 535.58 70 / 20 / 10 520.67 80 / 15 / 5 496.05

[0036] As can be seen from Table 3, except that the breaking strength of the yarn of a kind of jute / cotton / polyester blend ratio that blending ratio is 80 / 15 / 5 (wt %) does not reach 520 (cN), all the other have exceeded 520 (cN ), the breakin...

Embodiment 3

[0038]Also can add length about 31~35 millimeters in jute and cotton fiber in order to strengthen the breaking strength of jute and cotton fiber blended yarn, the ramie fiber of fineness about 1200 (Nm) carries out fiber mixing. The breaking strength of the 12-count yarns of the three fiber blends mixed according to different weight percentages are shown in the table below.

[0039] Table 4 Breaking strength of jute / cotton / ramie blended yarn with 12 counts (s)

[0040] Proportion (wt%) Breaking strength (cN) 20 / 65 / 15 589.76 25 / 50 / 25 638.03 30 / 50 / 20 604.58 30 / 40 / 30 623.45 40 / 45 / 15 588.56 45 / 50 / 5 534.79 50 / 28 / 22 579.08 60 / 30 / 10 536.98 70 / 20 / 10 530.28 80 / 15 / 5 500.69

[0041] As can be seen from Table 4, except that the breaking strength of the yarn of a kind of jute / cotton / ramie blending ratio that blending ratio is 80 / 15 / 5 (wt %) does not reach 520 (cN), all the others have exceeded 520 (cN ), the breaking streng...

Abstract

A rough fiber / fine fiber blended yarn comprises two types of fiber of rough fiber and fine fiber, as well as at least another one type of intermediate fiber with the fineness which is between the fineness of the rough fiber and the fine fiber, and any two types of fiber with the similar fineness in a variety of fibers can be mutually cohered. As at least another one type of intermediate fiber with the fineness which is between the fineness of the rough fiber and the fine fiber is added in the fiber mixture of the rough fiber / fine fiber blended yarn, the breaking strength of the blended yarn is improved. If the intermediate fiber with one fineness is added, the intermediate fiber can be cohered with the rough fiber and can also be cohered with the fine fiber; if various types of intermediate fiber with different finenesses are added, the various types of the intermediate fibers can also be well cohered together, so that the various types of fibers can be cohered and wound together in blending and the breaking strength of the blended yarn can be further well enhanced.

Description

technical field [0001] The invention relates to a blended yarn containing different coarse and fine fiber materials. Background technique [0002] Blending has become one of the development trends of fabrics. There are many ways and methods of blending, such as natural fiber blending, intervening functional fiber blending, chemical fiber and natural fiber blending, etc. It is difficult to directly distinguish whether a fabric is cotton, Wool, hemp, silk or chemical fiber, the diversification of textile raw materials makes them have me in you, and you in me. Common blended yarns in the market include cotton / polyester blended yarn, cotton / linen blended yarn, cotton / ramie blended yarn, wool / viscose blended yarn, etc. The fineness is close, the difference between the fineness metric counts of the two fibers is not more than 5 times, the difference is not big, and the strength of the blended yarn is better. However, when using two kinds of fiber raw materials with large differe...
