Abstract
A hemp/silk/polyamide blended yarn comprises three types of fiber of hemp, silk and polyamide. The weight of the silk fiber accounts for 10-40 percent by weight of the total weight of the hemp, the silk and the polyamide fiber. The fineness difference between the silk fiber and the hemp fiber and the fineness difference between the silk fiber and the polyamide fiber are both small. When being blended, the silk fiber of the blended yarn can be cohered with the hemp fiber and can also be cohered with the polyamide 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 silk fiber which can lead the breaking strength of the yarn to be more satisfactory during the blending of the hemp fiber/polyamide 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 hemp, silk, three kinds of fibers of polyamide fibre.
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 such as polyamide fibre, wool, chemical fibre, silk etc. carry out blending/interweave 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.Hemp has many distinctive advantages: hemp has the anti-mildew bacteriostasis, and staphylococcus aureus, pseudomonas aeruginosa, Escherichia coli, Candida albicans are had tangible fungistatic effect; It is the ultraviolet ray of maskable more than 95% that general hemp need not special arrangement; Hemp has good heat-resistant, and hemp does not change color yet in the time of 370 ℃; Dry hemp is the non-conductor of electricity, and its anti-electrical breakdown capability is higher by about 30% than cotton fiber; Wear the hemp clothes and compare, can make low about 5 ℃ of human body sensory temperature with COTTON FABRIC.Frivolous, the abundant soft soft cunning of matte that the fabric of nylon fibre has is worn comfortable resisting cold again, advantages such as antistatic.And numb bright and beautiful blending product has the advantage of two kinds of fibrous materials concurrently, has excellent application value.When needs are weaved cheap, practicality is good numb bright and beautiful blended yarn, be that main raw material carries out blending often with hemp and nylon fibre.But hemp can not be a fine fibre, because hemp is a bundle fiber, the division degree is poorer than other crudefiber crops, and fiber is relatively thicker, hard, and spinnability is very poor, and this has restricted the application of hemp aspect garment material greatly.When adopt these two kinds of hemp and nylon 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 thicker flax fibre bending is less in spinning process, thinner nylon fibre can be wrapped in thicker hemp around, crooked degree is bigger, rather than as both mutual obvolvents during blending between the close fiber of thickness, the hemp and the cohesive force between two kinds of fibers of polyamide fibre 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 by adding silk fiber, proposes the good polyamide fibre linen blended yarn of a kind of ultimate strength for solving the problem that hemp/polyamide fibre blended yarn ultimate strength is low of prior art.
And then the invention provides when hemp/polyamide fibre blending ratio not simultaneously, preferably add the number range of the percentage by weight of silk fiber.
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of hemp/silk/polyamide fibre blended yarn comprises hemp, silk and three kinds of fibers of polyamide fibre, it is characterized in that the weight of described silk fiber accounts for 10～40wt% of described hemp, silk and nylon fibre gross weight.
The weight ratio of described hemp and described nylon fibre is 3:1～4:1, and the weight of described silk fiber accounts for 10～20wt% of described hemp, silk and nylon fibre weight gross weight.
The weight ratio of described hemp and described nylon fibre is 13:7～7:3, and the weight of described silk fiber accounts for 20～30wt% of described hemp, silk and nylon fibre weight gross weight.
The weight ratio of described hemp and described nylon fibre is 9:11～1:1, and the weight of described silk fiber accounts for 25～30wt% of described hemp, silk and nylon fibre weight gross weight.
The weight ratio of described hemp and described nylon fibre is 7:13～2:3, and the weight of described silk fiber accounts for 30～35wt% of described hemp, silk and nylon fibre weight gross weight.
The weight ratio of described hemp and described nylon fibre is 1:3～3:7, and the weight of described silk fiber accounts for 35～40wt% of described hemp, silk and nylon 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 hemp and nylon fibre all less, the silk fiber of fibre fineness between described hemp and two kinds of fibers of polyamide fibre, because thickness, the soft or hard degree of silk fiber and hemp and two kinds of fibers of polyamide fibre all differ little, therefore can obvolvent well in the spinning process, can improve the ultimate strength of blended yarn.
When 2, the hemp/nylon 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 silk fiber.
The specific embodiment
Since hemp through coming unstuck, fibre fineness after the health is at 400～500 (Nm), and the fineness of nylon fibre is about 6000 (Nm), the metric count of nylon fibre fineness (Nm) is 12～15 times of hemp.Hemp and nylon fibre are through after the blending, and the flexural deformation degree of hemp wherein is less, and nylon fibre be wrapped in hemp 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 big flax bunch fiber and length when 25～33 millimeters nylon fibre carries out blending, the ultimate strength of the hemp of its different blending rates/12 (s) yarns of polyamide fibre blending is as shown in the table.
