Embodiment
The characteristics of present invention is directed to kapok/silk/cotton blended yarn, spin kapok/cotton blend ratio respectively 0/100,10/90,20/
80th, 30/70,40/60,50/50 scribbled, spinning kapok/cotton blending yarn technological process are：Opening picking, plus and crude oil,
Cotton carding, drafting, rove, spun yarn.
Opening picking step：Because bombax cotton is very loose, strength is low, in opening picking, fiber is easily damaged and is broken, and
And its light weight, easy flyings, fibre damage and be lost in serious/pollution air, so using manually bombax cotton is carried out shredding,
Removal of impurities, shredding, removal of impurities are carried out to cotton fiber using machine.
Add and crude oil step：It is very loose between fiber because bombax cotton is very light and short, more fluffy in itself, to improve it
Spinnability, bombax cotton is handled with a certain amount of and crude oil, makes bombax cotton that there is certain regain, increased weight, subtract
Few flyings and electrostatic, increase the cohesive force and toughness of bombax cotton, improve its spinnability.With being mixed with crude oil with water, (proportioning is
1/9), uniformly it is sprayed on bombax cotton, vexed 24 hours, infiltration is uniform.
Cotton carding step：The bombax cotton treated with crude oil is well mixed with cotton fiber by preset ratio, spread in proportion
Layer feeding carding machine.It should be noted that bombax cotton should keep 11%-13% regains, otherwise, flyings are excessive, and kapok is fine
Dimension easily loss, if conversely, humidity is excessive, is unfavorable for combing；Raw material will be laid uniformly, and cotton layer is unsuitable blocked up；Transported using low speed
Turn, reduce the loss of bombax cotton, low, more crisp, the high easy damaged fiber of speed of kapok strength, also make the increase of web cotton grain, reduce
Carding effect.
Drafting step：Bombax cotton and the cotton fiber mixing carded sliver, mix than respectively 0/100,10/90,20/80,30/70,
40/60、50/50.It should be noted that processing environment ensures more than 70% humidity, strip strength is relatively low, and loosely, mutually
Mutually easily stick together, strip quantitatively can not be too light, easy broken strip；Bombax cotton length is short, and close number should not be excessive, easily cause bar
It is dry to deteriorate；Shaping weight can not be too light, easy broken strip；Bombax cotton length is shorter, when with the fiber blend longer than its length, needs
Consider that roller grips gauge, improve the control to bombax cotton.
Rove step：Bombax cotton mixes ripe bar with cotton fiber, mix than respectively 0/100,10/90,20/80,30/70,
40/60、50/50.It should be noted that Roving Frames reduce the friction of sliver and intake mechanism, broken strip is prevented；Low-speed running,
Tension force grasp less than normal, reduce rove broken end；It is appropriate to increase roving twist factor, ensure rove shaping.
Spun yarn step：Bombax cotton and cotton fiber blended roving, mix than respectively 0/100,10/90,20/80,30/70,
40/60、50/50.It should be noted that using low speed, small drawing-off, the technological principle twisted greatly, to increase spun yarn strength, reduce
Broken end.
Kapok/cotton blend ratio respectively 0/100,10/90,20/80,30/70,40/60,50/ is obtained using above-mentioned steps
After 50 scribbled, experiment test ultimate strength, fracture growth rate, yarn evenness, yarn hair are passed through using the yarn
Plumage；Plain weave, 2/2 twill left to right is respectively adopted using the yarn, flies satin weave and obtains fabric for 8 piece 5, passes through experiment test kapok/cotton
The Air permenbility of different blending ratio fabrics, warming rate, abrasion resistance, warp-wise crease recovery rate, broadwise crease recovery rate contrast table, with
And the warming rate of fabric tissue.
Below by experimental result, to illustrate that kapok/cotton blend compares the influence of scribbled performance.Table 1 is kapok/cotton
The ultimate strength of different blending ratio yarns, fracture growth rate, yarn evenness, Yarn filoplume contrast table, as can be seen from Table 1：
The ultimate strength of yarn constantly declines with the increase of kapok blending ratio, when the content of bombax cotton is less than 30%, blending
The ultimate strength of yarn declines less, and when kapok content is 30%, the ultimate strength of yarn be 2.4N, and broken end is failed to understand during spinning
It is aobvious；But when kapok content increases to 40%, ultimate strength is only 1.5N, is easy to break end in spinning process, resultant yarn
It is relatively difficult.When bombax cotton content is 50%, compared with pure spinning yarn, the ultimate strength of scribbled about declines 70%.
This be primarily due to bombax cotton compared with cotton fiber strength it is low, length is short, short fibre content is more, when bombax cotton content is less,
The ultimate strength of mixed yarn is mainly embodied by cotton fiber, thus be not susceptible to during by force-extension it is interfibrous slip it is existing
As gradually embodying the strength of bombax cotton with the increase of bombax cotton content, interfibrous sliding increases, and causes yarn
Ultimate strength decline, extension at break reduce.In addition, the elongation at break of scribbled is with kapok as can be seen from Table 1
The increase of fiber content and decline, when kapok content is 50%, the elongation at break of yarn declines 50% or so compared with Quality Pure Cotton Yarn Production,
In the Tensile Fracture Process of different blending ratio yarns, the ultimate strength of mixed yarn does not have to be occurred with the change of blending rate
Lower pit.It is smooth that this is primarily due to bombax cotton surface, and broken filament strength is less than cotton fiber, during by force-extension
Easily slide in the fibre, so the elongation at break of mixed yarn declines substantially, but continue to increase with bombax cotton content
Add, the chopped fiber in mixed yarn is more and more more, so as to cause the ultimate strength of yarn and elongation at break to reduce obvious, broken end increasing
Add.
In addition, from table 1 it follows that with kapok/cotton blend than increase, it is the strip dry CV value of mixed yarn, details, thick
Section is continuously increased, this is primarily due to, and bombax cotton length is short, and distribution of lengths dispersion is big, regularity is poor and fibre fineness is small,
It is strongly relatively low, cotton knot is also easy to produce during spinning, in addition, also as the light weight of bombax cotton, fiber surface is smooth, rubs
It is small to wipe coefficient, the fiber of yarn body is difficult to control in drafting process, fiber is also easy to produce sliding so that the strip dry CV value of yarn,
Details, slubbing increase.
In addition, it can also be seen that as the increase of bombax cotton content, the increasing degree of mixed yarn filoplume are in from table 1
First big after small big trend again.This is primarily due to that bombax cotton length is shorter, with the increase of its content, the short fibre in yarn
Dimension hplc increase, corresponding fiber head end increase, Yarn filoplume increase.
The ultimate strength of 1 kapok of table/cotton difference blending ratio yarn, fracture growth rate, yarn evenness, Yarn filoplume contrast
Table
As can be seen here, bombax cotton content is very big to the performance impact of kapok/silk/cotton blended yarn.Bombax cotton content is less than
When 30%, the ultimate strength fall of mixed yarn is small, after bombax cotton content is more than 50%, the elongation at break of mixed yarn
Decline obvious.Bombax cotton content has a great influence to mixed yarn filoplume, with the increase of bombax cotton content, mixed yarn filoplume
Increasing degree is in first big after small big trend again；Increasing of Unevenness CV, details and the slubbing of mixed yarn also with bombax cotton content
Add and increase, when bombax cotton content is more than 60%, resultant yarn is difficult.It is thus regarded that bombax cotton can be mixed with cotton fiber
Spin, but blending ratio is not preferably greater than 30%, otherwise has considerable influence to yarn property and weaving process.
Below by experimental result, to illustrate that kapok/cotton blend compares the influence of scribbled wearability.Table 2 is wood
The Air permenbility of cotton/cotton difference blending ratio fabric, warming rate, abrasion resistance, warp-wise crease recovery rate, the contrast of broadwise crease recovery rate
Table.From Table 2, it can be seen that kapok/cotton blended fabric is better than the permeability of pure cotton fabric, and with the ratio of bombax cotton
Example increase, gas permeability are become better and better, and this is due to that bombax cotton has larger middle cavity, is advantageous to air permeable.In addition, from
As can be seen that the warming rate of kapok/cotton blended fabric is substantially higher than pure cotton fabric in table 2, and with the ratio of bombax cotton
Increase, warmth retention property are become better and better, and this is due to that the hollow intracavitary of bombax cotton is detained large quantity of air, can obtain preferable warmth retention property
Energy.Meanwhile from Table 2, it can be seen that under the conditions of identical tissue density, kapok/cotton blended fabric wearability is compared with pure cotton fabric
Difference, and with the ratio increase of bombax cotton, worse and worse, this is primarily due to the strength of kapok/silk/cotton blended yarn to wearability
It is low than Quality Pure Cotton Yarn Production with extending, cause kapok blend fabric when being worn, kapok yarn is than Quality Pure Cotton Yarn Production more cracky, institute
It is low compared with pure cotton fabric with its wearability, it is seen then that wearability is a shortcoming of kapok blend fabric, should try one's best and avoid use from passing through
The position often worn.It can also be seen that kapok/cotton blended fabric anti-crease property is poor compared with pure cotton fabric from table 2, and with wood
The ratio increase of cotton fiber, worse and worse, the bending rigidity that this is primarily due to bombax cotton is big for wrinkle resistance, the soft wood of appearance
Cotton fiber, it is actual that there is stronger anti-crease property energy, but such as there are wrinkle in it, and the recoverability of wrinkle is poor.
2 kapoks of the table/Air permenbility of cotton difference blending ratio fabric, warming rate, abrasion resistance, warp-wise crease recovery rate, broadwise
Crease recovery rate contrast table
In addition, contrast plain weave, twill and satin weave weaving process, kapok/cotton blended fabric the same with common pure cotton fabric
In terms of gas permeability, warmth retention property, crease recovery, the wearability of kapok/cotton blended fabric is ordered as：Satin weave ＞ twills ＞ is put down
Line, just on the contrary, order is in terms of wearability：Plain weave ＞ twill ＞ satin weaves.
It can be seen that kapok/cotton blended fabric has reached the basic demand for taking fabric, and it is in warmth retention property, gas permeability side
Face is better than pure cotton fabric, but kapok blend fabric is due to the limitation of spinning process, on crease recovery and wearability compared with
Pure cotton fabric is poor.Gas permeability and warmth retention property according to kapok/bafta, it is proposed that the more loose fabric such as summer clothing fabric selection satin weave
Tissue, makes full use of its excellent permeability；For winter wearing fabric, it is proposed that the selection close plain weave of fabric tissue is knitted
Thing, it can preferably play its warmth retention property.
As can be seen that the blending ratio of kapok/cotton is preferably no more than 30/70, when kapok/cotton from the comparison of Tables 1 and 2
When blending ratio is 30/70, excellent scribbled performance and the excellent wearability of blend fabric can be taken into account.
In addition, in braiding, fabric can be by the tension force effect on machine so that fabric is constantly in the state of anxiety.
For fabric after lower machine, the disappearance of tension force causes the structure snd size of fabric can significant change.Therefore, it is necessary to the fabric after lower machine
Carry out some necessary heat treatments so that the dimensional structure of fabric is relative to keep stability.In the present invention at the sizing of fabric
Managing flow is：11min- rinsing 5min- dehydration 1min- rinsing 3min- dehydration 1min- rinsing 2min- dehydration 6min are washed, are passed through
Fabric tiling after heat treatment is dried.
Although using aforesaid way, the good kapok/cotton blending yarn of warmth retention property can be obtained, is with science and technology
Progressive and human living standard raising, also more and more higher, traditional dress can not meet the needs of wearing to the requirement to dress,
The idea that clothes are used to hide body resisting cold just occurs to change, and people increasingly thirst for a kind of clothes for adapting to climate change and asked
Generation.Traditional heat-preserving fabric is to reach insulation by the reflection to hot-fluid and isolation, the thickness of textile, still air and anti-
It is major influence factors to penetrate material, and thickness is bigger, density is closeer, it is more to include still air, then fabric insulation effect is better.Pass
The nice and cool fabric of system is by quick moisture absorption, leads wet and water evaporation to radiate.In general, textile surface is wet-guide quick-drying
Material.The thermoregulation effect of conventional fabrics is vulnerable to the influence of the deformation of material, external force, air pressure and moisture, to wet, cold and overheat ring
Border is not suitable with.
Phase-changing and temperature-regulating fabric is different from traditional warming, nice and cool fabric, is absorbed incessantly by the phase-change material in fabric
Temperature is adjusted with releasing energy, changes traditional insulation pattern so that fabric can be maintained at a comfortable temperature
Scope, make garment material more comfortableization, so as to meet people's requirement comfortable and easy to wear.Being mainly characterized by of phase-change material works as ring
When border temperature or human skin temperature reach phase-change material fusing point in clothes, heat is absorbed, while switchs to liquid from solid-state, so
Of short duration cooling effect will be produced in clothes internal layer.Heat may be from human body (heat etc. as caused by motion), also may be used
It can be raised from environment temperature.If used in cold environments, when environment temperature or skin temperature are less than phase-change material fusing point
When, phase-change material will be transformed back into solid-state by liquid, while the heat of storage is discharged in transition process, there is provided of short duration heating effect
Fruit.Phase-change material is changed by such mode to temperature plays cushioning effect, reduces the suddenly change of wearer's skin temperature,
Make people feel comfortable.
The present invention is from the use function and added value angle that improve kapok/silk/cotton blended yarn, research and probe phase-change material
The process route and process conditions being combined with kapok/silk/cotton blended yarn fabric, new kapok/silk/cotton blended yarn phase transformation product is made,
Good kapok/the silk/cotton blended yarn of script warmth retention property is set to add the function of heat-accumulation temperature-adjustment.

1.5 times of amount, can realize good cladding, and do not change the hot physical property of paraffin substantially to paraffin.
In order that kapok/silk/cotton blended yarn fabric after arranging can contain more phase-change microcapsules, possess more phases
Become enthalpy, i.e., the suitable microenvironment of human body that clothes can maintain a more long in transition temperature range, the present invention uses padding method so that
Phase-change microcapsule can be included in fabric gap.Padding method is usually that phase-change microcapsule stirs to be distributed in solution,
Microcapsules are made to be attached in fabric face or gap by other crosslinking agents again.
The finishing technique of kapok/silk/cotton blended yarn fabric of the present invention is：With dressing liquid, pad (two leachings two are rolled), drying, roasting
Dry.
Under certain condition effect, crosslinking agent can react with the group on fiber, so as to surmount hydrogen bond model moral
Hua Li, because covalent bond power between crosslinking agent and fiber be present.And different types of crosslinking agent to microcapsules adhere to kapok/
The fastness of silk/cotton blended yarn fabric is not quite similar, and is knitted so can typically select a kind of suitable crosslinking agent to carry out kapok/silk/cotton blended yarn
Thing arranges.The present invention selects three types crosslinking agent, respectively crosslinking agent AF6680, crosslinking agent AF6100 and crosslinking agent APF-
101 pairs of kapoks/silk/cotton blended yarn fabric carries out padding finishing.
By experiment, with crosslinking agent AF6680, crosslinking agent AF6100 and crosslinking agent APF-101 to kapok/cotton blend
Rate of body weight gain after yarn woven fabric arranges is respectively 5.49%, 6.57% and 11.89%, can preliminary judgement crosslinking agent APF- from data
101 growth rate is high.As can be seen here, there is good adhesiving effect using arrangements of the crosslinking agent APF-101 to phase-change microcapsule, it is right
The gaining effect of phase-change microcapsule is apparently higher than other two kinds.
After once water-fastness, using kapok when crosslinking agent AF6680, crosslinking agent AF6100 and crosslinking agent APF-101/
Residual quantity percentage on silk/cotton blended yarn fabric is respectively 64.94%, 66.75% and 97.32%.As can be seen here, crosslinking is passed through
The phase-change microcapsule of agent APF-101 adhesions is firmly sticked together on bafta very much, does not there is very big loss.
After eight times are water-fastness, using kapok when crosslinking agent AF6680, crosslinking agent AF6100 and crosslinking agent APF-101/
Residual quantity percentage on silk/cotton blended yarn fabric is respectively 40.61%, 38.76% and 85.97%.Using crosslinking agent AF6680 and
Phase-change microcapsule residual quantity percentage on crosslinking agent AF6100 kapok/silk/cotton blended yarn fabric is less than half, and crosslinking agent
APF-101 residual quantity percentage is also up to 85.97%.
In summary, finishing agents of the crosslinking agent APF-101 more suitable for phase-change microcapsule to kapok/silk/cotton blended yarn fabric.
By experiment, with the continuous increase of crosslinking agent APF-101 mass concentrations, rate of body weight gain gradually increases.From resistance to
Phase-change microcapsule residual quantity percentage analysis after washing, in crosslinking agent quality 29~43g/L of concentration, it is water-fastness after residual
Amount percentage gradually increases.After crosslinking agent quality concentration 43g/L, variation tendency is gradually reduced again.It is 43g/L in mass concentration
When, residual quantity percentage can meet more than 82.63%, so 43g/L is the appropriate mass concentration of crosslinking agent.
By experiment, between 90-160 DEG C, baking temperature influences not on the rate of body weight gain of kapok/silk/cotton blended yarn fabric
Substantially.After once water-fastness, at 90 DEG C, phase-change microcapsule residual quantity percentage is relatively low, and its reason is probably that crosslinking agent is anti-
Should be incomplete, adhesion fastness of the phase-change microcapsule to bafta is little, easily washes and removes.After baking temperature raises, wood
Residual quantity on cotton/silk/cotton blended yarn fabric gradually increases.After baking temperature is more than 120 DEG C, phase-change microcapsule residual quantity hundred
Ratio is divided also not significantly reduce without showed increased, show phase-change microcapsule in this kapok/silk/cotton blended yarn textile finishing temperature range
Interior not destroyed, phase change paraffin is all intact to be coated in microcapsules.Therefore, baking temperature of the invention selects 120 DEG C.
By experiment, time lengthening is baked, kapok/silk/cotton blended yarn fabric rate of body weight gain does not change significantly.Observation
Its it is water-fastness once with water-fastness eight times after phase-change microcapsule residual quantity percentage, when baking time 35s, its residual quantity hundred
Divide than relatively low, reason is that the time is few, and the reaction time of crosslinking agent is inadequate so that crosslinking agent does not react completely.When baking
Between after 90s, the change of phase-change microcapsule residual quantity percentage is very slow.Therefore, it is of the invention to bake selection of time 90s.
By experiment, kapok/silk/cotton blended yarn fabric has an obvious heat absorption peak after arrangement, and its phase transition temperature exists
28.9 DEG C, phase transformation enthalpy is 3.4J/g：Compared with untrimmed kapok/silk/cotton blended yarn fabric, kapok/cotton blend after arrangement
Yarn woven fabric has obvious heat-accumulation temperature-adjustment function, and user can experience obvious constant-temperature warm-keeping effect.
To sum up, the crosslinking agent selected of the present invention is APF-101, and crosslinking agent quality concentration is 43g/L, 120 DEG C of baking temperature,
It is 90s to bake the time.Arranging flow is：With dressing liquid, (crosslinking agent quality concentration is 43g/L, and phase-change microcapsule mass concentration is
55g/L, bath raio 25：1), pad (pick-up 85%, two leachings two are rolled), 75 DEG C of drying 60s, 120 DEG C bake 90s.
