Abstract
A jute/hemp/cotton blended yarn comprises three types of fiber of jute, hemp and cotton and is characterized in that the weight of the hemp fiber accounts for 10-40 percent by weight of the total weight of the jute, the hemp and the cotton fiber. The fineness difference between the hemp fiber and the jute fiber and the fineness difference between the hemp fiber and the cotton fiber are both small. When being blended, the hemp fiber of the blended yarn can be cohered with the jute fiber and can also be cohered with the cotton fiber, thereby enhancing the cohesion among different types of fiber; and the spun blended yarn has better breaking strength. The invention discloses the content range of the added hemp fiber which can lead the breaking strength of the yarn to be more satisfactory during the blending of the jute fiber/cotton fiber with different weight percentages.
Description
Technical field
The present invention relates to a kind of blended yarn, relate in particular to a kind of blended yarn that contains jute, hemp, cotton three kinds of fibers.
Background technology
Raising along with the human substance life horizontal, originally people more from having transferred in the requirement to its comfortableness the concern of dress ornament durability, because flax fibre has sucting wet air permeability, low static behaviour and good antibacterial characteristics preferably, crudefiber crop fabric clothing lining more and more is subjected to people's favor.The lining of existing crudefiber crop fabric clothing is meant mainly that flax, ramie raw materials or this type of raw material and other fiber carry out blending/interweave as cotton, wool, chemical fibre, silk etc. and the lining made.But, make that the crudefiber crop textiles does not have to be more widely used because flax, ramie price are higher.And jute is the second-biggest-in-the-world cellulose fibre that is only second to cotton, and it is cheap, and compares with flax, ramie and to have better hygroscopicity and drapability, and antibacterial ability is only second to hemp, has huge using value and potentiality to be exploited.Because the content of lignin higher (can reach 10-13wt%) in the jute, than high several times of flax, fiber is very thick, hard, and spinnability is very poor, and this has restricted the application of jute aspect garment material greatly; In addition, the clothes that cotton fiber is weaved out have moisture absorption, ventilative, no feeling of oppression and heat, good hand touch, and the while does not have the advantage of electrostatic phenomenon yet; And the cotton ramie blended spinning product has the advantage of two kinds of fibrous materials concurrently, has excellent application value.When needs are weaved the cotton ramie blended spinning yarn cheap, that practicality is good, need be that main raw material carries out blending with tossa and cotton fiber.But when adopt these two kinds in tossa and cotton fiber slightly, the fiber that carefully differs greatly is during as the raw material blending, because both thickness, soft or hard degree difference are very big, the degree of thick tossa bending is less in spinning process, thinner cotton fiber can be wrapped in thicker tossa around, crooked degree is bigger, rather than as both mutual obvolvents during blending between the close fiber of thickness, cohesive force between the jute that causes carefully, slightly differs greatly and the cotton two kinds of fibers is less, the blended yarn that spins out is easy to fracture, and yarn strength is lower.
Summary of the invention
The present invention by adding hemp, proposes the good cotton ramie blended spinning yarn of a kind of ultimate strength for solving the low problem of jute/cotton blended yarn ultimate strength of prior art.
And then the invention provides when the jute/cotton blending ratio not simultaneously, preferably add the number range of the percentage by weight of hemp.
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of jute/hemp/cotton blended yarn comprises jute, hemp and cotton three kinds of fibers, it is characterized in that the weight of described hemp accounts for 10～40wt% of described jute, hemp and cotton fiber gross weight.
The weight ratio of described tossa and described cotton fiber is 3:1～4:1, and the weight of described hemp accounts for 10～20wt% of described jute, hemp and cotton fiber weight gross weight.
The weight ratio of described tossa and described cotton fiber is 13:7～7:3, and the weight of described hemp accounts for 20～30wt% of described jute, hemp and cotton fiber weight gross weight.
The weight ratio of described tossa and described cotton fiber is 9:11～1:1, and the weight of described hemp accounts for 25～30wt% of described jute, hemp and cotton fiber weight gross weight.
The weight ratio of described tossa and described cotton fiber is 7:13～2:3, and the weight of described hemp accounts for 30～35wt% of described jute, hemp and cotton fiber weight gross weight.
The weight ratio of described tossa and described cotton fiber is 1:3～3:7, and the weight of described hemp accounts for 35～40wt% of described jute, hemp and cotton fiber weight gross weight.The present invention has the following advantages:
1, because in the fiber of using always in the spinning, crude fibre is bigger than the rigidity of fine fibre, that is to say generally, thicker fiber stiffness is bigger, and the rigidity of thinner fiber is less, so it is thick, when thin two kinds of fibre finenesses differ big, crude fibre in blending is because rigidity is bigger, be not easy to bend, distortion, and fine fibre rigidity is little, comparatively soft, very easily bend, distortion, therefore can appear at fiber thinner in the spinning process can be wrapped in thicker fiber around, rather than as both mutual obvolvents during blending between the close fiber of thickness, cause thin, cohesive force between two kinds of fibers that slightly differ greatly is less, and the blended yarn that spins out is easy to fracture, and yarn strength is lower.Blended yarn of the present invention, by in mixed with fibers, add another kind of at least and the fineness difference of tossa and cotton fiber all less, the hemp of fibre fineness between described jute and two kinds of fibers of cotton, because thickness, the soft or hard degree of hemp that adds and jute and cotton two kinds of fibers all differ little, therefore can obvolvent well in the spinning process, can improve the ultimate strength of blended yarn.
When 2, the tossa/cotton fiber that the invention discloses Different Weight percentage carries out blending, make the ultimate strength of yarn comparatively desirable, add the weight percentage scope of hemp.
The specific embodiment
Since tossa through coming unstuck, fibre fineness after the health is at 400～500 (Nm), and the fineness of cotton fiber is about 6000 (Nm), the metric count of cotton fiber fineness (Nm) is 12～15 times of tossa.Tossa and cotton fiber are through after the blending, and the flexural deformation degree of tossa wherein is less, and cotton fiber be wrapped in tossa around, the obvolvent of two kinds of fibers that these two kinds of fineness differ greatly is in bad order.At this moment, with length in 27～30 millimeters jute bundle fiber and length when 25～33 millimeters cotton fiber carries out blending, the ultimate strength of 12 (s) yarns of the jute/cotton blending of its different blending rates is as shown in the table.
