Embodiment 1

[0028] The flax fiber with a length of 27-33 mm and a fineness of about 1200 (Nm) is added as an intermediate fiber for fiber mixing with jute fiber and cotton fiber. The fineness metric count (Nm) of the flax fiber is 2.4 to 3 times that of the jute fiber fineness metric count (Nm), and the fineness metric count (Nm) of the cotton fiber is 2.4 to 3 times that of the flax fiber. 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 12 counts (s) of jute / cotton / flax blended yarns with different blending ratios is shown in the table below:

Embodiment 2

[0035] 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.

[0039] It can be seen from Table 3 that except for a jute / cotton / polyester blended yarn with a blending ratio of 80 / 15 / 5 (wt%), the breaking strength of the yarn did not reach 520 (cN), and the rest exceeded 520 (cN). ), the breaking strength of the blended yarn is better; especially when the weight percentage of the polyester fiber is 20, 25 and 30 (wt%), the breaking strength of the blended yarn exceeds 618 (cN), at this time the blended yarn The b...

Embodiment 3

[0041] In order to enhance the breaking strength of jute and cotton fiber blended yarn, ramie fibers with a length of about 31-35 mm and a fineness of about 1200 (Nm) can be added to the jute and cotton fibers for 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.

[0044] It can be seen from Table 4 that the breaking strength of a jute / cotton / ramie blended yarn with a blending ratio of 80 / 15 / 5 (wt%) did not reach 520 (cN), and the rest exceeded 520 (cN ), the breaking strength of the blended yarn is better; especially when the weight percentage of the polyester fiber is 20, 25 and 30 (wt%), the breaking strength of the blended yarn exceeds 600 (cN), when the weight percentage of the flax fiber When the percentage is 25 (wt%), the breaking strength of ...

Abstract

The invention provides a blended yarn of a coarse fiber and a fine fiber, containing the coarse fiber and the fine fiber, as well as at least another one intermediate fiber of which the fineness is between the finenesses of the coarse fiber and the fine fiber, wherein any two of multiple fibers, of which the finenesses approach, can cohere with each other. Through the adding of at least another one intermediate fiber of which the fineness is between the finenesses of the coarse fiber and the fine fiber, into a fiber mixture, the breaking strength of the blended yarn is improved. If being added, the intermediate fiber with the same fineness can cohere with the coarse fiber, and can also cohere with the fine fiber; if being added, the intermediate fibers with various finenesses can mutually cohere together; and in such a way, various fibers in the blended yarn can cohere and intertwine together, so that the breaking strength of the blended yarn is enhanced.

Description

[0001] This application is a divisional application with the application number 200810179233.7, the application date is December 1, 2008, and the invention title is "Coarse and Fine Fiber Blended Yarn". technical field [0002] The invention relates to a blended yarn containing different coarse and fine fiber materials. Background technique [0003] 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 ...
