Abstract
A jute/ramie/polyester blended yarn comprises three types of fiber of jute, ramie and polyester and is characterized in that the weight of the ramie fiber accounts for 10-40 percent by weight of the total weight of the jute, the ramie and the polyester fiber. The fineness difference between the ramie fiber and the jute fiber and the fineness difference between the ramie fiber and the polyester fiber are both small. When being blended, the ramie fiber of the blended yarn can be cohered with the jute fiber and can also be cohered with the polyester 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 ramie fiber which can lead the breaking strength of the yarn to be more satisfactory during the blending of the jute fiber/polyester 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, ramie, three kinds of fibers of terylene.
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 that mainly 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 make, 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 weaved out of polyster fibre have advantages such as voidage height, good permeability, long service life; And fiber crops are washed the advantage that blending product has two kinds of fibrous materials concurrently, have excellent application value.When needs are weaved linen-cotton cheap, that practicality is good and washed blended yarn, need be that main raw material carries out blending with tossa and polyster fibre.But when adopt these two kinds of tossa and polyster fibres 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 polyster fibre 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, the jute and the cohesive force between two kinds of fibers of terylene that cause carefully, slightly differ greatly are less, the blended yarn that spins out is easy to fracture, and yarn strength is lower.
Summary of the invention
The present invention, proposes the good fiber crops of a kind of ultimate strength and washs blended yarn by adding ramee for solving the problem that jute/the dacron blended yarn ultimate strength is low of prior art.
And then the invention provides when jute/blend polyester than not simultaneously, preferably add the number range of the percentage by weight of ramee.
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of jute/ramie/terylene blended yarn comprises jute, ramie and three kinds of fibers of terylene, it is characterized in that the weight of described ramee accounts for 10～40wt% of described jute, ramie and polyster fibre gross weight.
The weight ratio of described tossa and described cotton fiber is 3:1～4:1, and the weight of described ramee accounts for 10～20wt% of described jute, ramie and polyster fibre gross weight.
The weight ratio of described tossa and described cotton fiber is 13:7～7:3, and the weight of described ramee accounts for 20～30wt% of described jute, ramie and polyster fibre gross weight.
The weight ratio of described tossa and described cotton fiber is 9:11～1:1, and the weight of described ramee accounts for 25～30wt% of described jute, ramie and polyster fibre weight gross weight.
The weight ratio of described tossa and described cotton fiber is 7:13～2:3, and the weight of described ramee accounts for 30～35wt% of described jute, ramie and polyster fibre weight gross weight.
The weight ratio of described tossa and described cotton fiber is 1:3～3:7, and the weight of described ramee accounts for 35～40wt% of described jute, ramie and polyster fibre 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 fineness difference another kind of at least and tossa and polyster fibre all less, the ramee of fibre fineness between described jute and two kinds of fibers of terylene, because thickness, the soft or hard degree of ramee and jute and two kinds of fibers of terylene all differ little, therefore can obvolvent well in the spinning process, can improve the ultimate strength of blended yarn.
When 2, the tossa/polyster fibre that the invention discloses Different Weight percentage carries out blending, make the ultimate strength of yarn comparatively desirable, add the weight percentage scope of ramee.
The specific embodiment
Since tossa through coming unstuck, fibre fineness after the health is at 400～500 (Nm), and the general fineness of more polyster fibre of using in blending is at 6000-25000Nm, be more than 6000 (Nm), so the metric count of polyster fibre fineness (Nm) is more than 12～15 times of tossa.Tossa and polyster fibre are through after the blending, and the flexural deformation degree of tossa wherein is less, and polyster fibre 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 polyster fibre carries out blending, the ultimate strength of 12 (s) yarns of the jute/blend polyester of its different blending rates is as shown in the table.
