Description
Technical field
This product is related to a kind of spinning product and its production technology, specifically a kind of bamboo fibre and acrylic fiber blending whirlpool
Flow spinning product and its Weaving method.
Background technology
As the improvement of people's living standards, the function of textile is no longer most basic warming, it is more to pursue
Novel, comfortable, fashion, environmental protection etc. some it is modern, emerging the effect of.Pass through the further investigation to future market demand, prediction, tune
Look into, with reference to the characteristics of existing new fiber materials and spinning method utilization, developed bamboo/nitrile 50/50
18.5tex it is vortexed textile product.
Vortex spinning is a kind of spinning method that latest developments are got up, and has unique yarn formation structure.The production developed
Product have many merits than traditional spinning.We analyze its advantage and disadvantage from air vortex spinning principle., will simultaneously in air vortex spinning
Ripe bar directly feeds drafting system after bar, and the fibre bundle after drawing-off exports from front roller nip, guidance cavity through nozzle and only
Twist with the fingers chamber and enter minor air cell, fibre bundle front end enters hollow pipe in the case where only twisting with the fingers chamber effect(Hollow spindle)It is interior, fiber tail end due to from
The effect of mental and physical efforts and air-flow, expansion is produced, form the fiber of free state(It can be described as tail end free end of fiber), free end fibre
Tie up the eddy current effect backspin formed in peripheral jet hole ejection air-flow to transfer to twist resultant yarn, drawn by hollow pipe, be wound into bobbin
Yarn, after fiber enters nozzle, nozzle box(Minor air cell)Interior space sudden enlargement, the outer layer fiber of fibre bundle are by radial effect and swollen
Swollen expansion.The front end of fiber is still in yarn body, is only twisted with the fingers chamber and introduced in hollow pipe;, free end is formed, and with rotary pneumatic
Stream, the surrounding of yarn body core fibre is separated from certain direction in fiber tail end(Swirling eddy direction)Winding, complete adding for yarn
Twist with the fingers, its twist principle is as shown in the figure.An important function for only twisting with the fingers chamber is that guiding fiber head end enters in hollow pipe, fiber head end
Into after hollow pipe, tail end expansion, and resultant yarn is twisted by air-flow, form bright and clean the tightly twisting of internal fiber parallel outer fiber parcel
Yarn.The yarn being spun into through yarn clearer, after Yarn Defect is removed, is winding on bobbin again.
Analyzed from vortex spinning yarn formation structure, vortex spinning is to make the head end of fiber into yarn using the vortex of compressed air
The heart is assembled, and the centre of yarn is formed the outer layer of yarn with other fiber spoolings into straight yarn untwisted state, the lower end of yarn.
On the other hand, minimum fiber is blown away by compressed air, and advantage spinning fiber every is all twisted into the center of yarn body, fine by other
The tail end covering of dimension.In the inside of yarn, fiber forms the solid construction without malleable, and outside forms and mutually tangles parcel
Web.Therefore, Air Vortex Spun Yarn turns into the minimum yarn of filoplume.
Due to the special yarn formation structure of vortex spinning so that the fabric of the yarn, advantage protrude.First, few filoplume, makes
The anti-fluffing of fabric, pilling tendency and wearability are particularly excellent, smooth appearance, solid yarn body construction in addition so that fabric chi
Very little stability, skew of weft, coloring are protected color, washing fastness etc. advantage and protruded.Meanwhile the arrangement of the non-twist parallel fibers in yarn body center
Form, constitute the hydraulic pipeline of yarn body, it is ensured that the excellent moisture absorption of fabric, wet guiding function, the easy dress developed, motion
The sweat in the summer of sweltering heat is filled also to discharge rapidly, be not bound to, it is comfortable and easy to wear nice and cool.But feel is hardened under being
One step air vortex spinning needs the blemish in an otherwise perfect thing overcome.Belonging to novel spinning situation additionally, due to it, existing market kind is extremely single,
It is suitable only for spunbond glue fiber or low ratio terylene and viscose blended product.It is difficult various spinning to be present in other fibrous raw materials
Degree.We analyze the existing fibrous raw material in market one by one with reference to the market demand.It is final to determine bamboo fibre and acrylic fiber
Carry out blending, vortex spinning yarn of the exploitation with specific function.
Bamboo fibre is the novel green regenerated celulose fibre of China's self-developing development and industrialization production.The property of bamboo
Matter and special green processing technology, create some special efficacies that bamboo fibre is different from other fibers.Such as:Natural
The netted cross section of concrete dynamic modulus and irregular jagged edge structure, the shallower groove of longitudinal surface, are advantageous to lead wet and moisture absorption
Permeability, in transient absorption and moisture can be evaporated, its moisture absorption, moisture releasing are occupied first of each fiber.Therefore, there is " the fibre that can be breathed
The title of dimension ", this characteristic also cause bamboo fiber to have even dyeing, bright in colour, not viscous to take, not stagnant wet, to human body skin
With the characteristic such as comfortable, dry and comfortable well;The crystallinity of bamboo fibre 40%, make it have good pilling resistance and crease-resistant
Property, also cause fabric feeling and soft texture, it is bright and clean it is smooth, drapability is good, gas permeability is good, fine and smooth and be imbued with silk quality sensation, gives
A kind of comfort level of zero pressure of people;Other bamboo fiber is almost nil to 200-400nm ultraviolet ray transmissivity;Bamboo fibre
Can natural biology degraded and distinctive bacteria resistance itself cause bamboo fiber have excellent health care, antibacterial, deodorization,
The function such as green, being detected through authoritative institution of the State Administration of Textile Industry proves:Bamboo fibre has natural antibacterial action(Same
After bacterium dissipates 24 hours on different fiber cloths, bacterial death rate on bamboo fiber fabric is up to more than 70%).But bamboo is fine
In place of dimension also has some shortcomings, such as:Strongly relatively low, wearability is slightly worse.
Acrylic fibers are polyacrylonitrile fibre, and it is by more than 85% acrylonitrile and the high score of second, third other monomer copolymerization
The synthetic fibers of sub- polymer spinning.The property of acrylic fibers is similar to wool, so there is the title of " synthetic wool ".
Acrylic fiber is with conspicuous characteristics, is mainly manifested in the following aspects:Higher intensity, its fracture strength are higher than wool
1-2.5 times, wet strong also reach does strong 85-95%;Less fibre density, it is lighter than wool, because acrylic fiber is light, volume
It is fluffy, large quantity of air can be accommodated, thus, heat insulating ability is preferable;In addition, heat resistance is also preferable, continue 32 under 125 DEG C of hot-airs
My god, intensity can keep constant, and it softens sticking temperature and is also up to 200 DEG C;Optimal light resistance and against weather, in various weavings
In fiber, the light resistance and against weather of acrylic fibers are best, if only declining 20% in 1 year its intensity of atmospheric exposure;Higher change
Stability is learned, it is extremely stable in acid, oxidant or organic solvent and not mouldy, it is not afraid of and damages by worms;Acrylic fibers hygroscopicity is poor, mark
Quasi- regain is only 2.0%, and therefore, it has indeformable advantage after not afraid of water and lower water, can remain hairy, continuously
Washing smooth can still not wrinkled;In addition.Acrylic fibers are due to being used made from copolymerization method, therefore dyeability is preferable.In summary so that
Acrylic fabric has wool type outward appearance, and fabric is merrily and lightheartedly soft, and dyeability is good, good heat preservation performance, and sun-resistant and weather-resistant property is good, rich
Flexible, washing shrinkage is low, is unlikely to deform, the advantages that easily being done after washing.But easily fluffing, balling-up are that the unavoidable of acrylic fibers lacks
Point.
The product that we are developed has many advantages, such as:Prominent moisture absorption, perspiration functions;Higher anti-fluffing, balling-up and
Wrinkle resistance;Dimensional stability;Excellent wear-resisting, fast light, against weather;Preferably dyeing, colour retention and environmental protection, degraded, antibacterial,
The functions such as deodorization.Future market growth requirement is catered to again, and we take the lead in have developed the 18.5tex vortex spinnings of bamboo/nitrile 50/50
