Woven fabric is made to reach optimal warming effect on the premise of not increasing thickness.
Technical scheme: the production method of a kind of accumulation of heat heating varicosity warming woven fabric of double-decker yarn, including as follows
Step:
(1) selection of fibrous raw material
The yarn selected is: accumulation of heat heat generating fiber, regenerated celulose fibre, high shrinkage acrylic, water soluble vinylon chopped fiber,
Four-in-one blending core-spun double-layer structure yarn, selected yarn linear density scope is at 14.8tex～40tex, owing to being that color spins
Yarn, can save dyeing process；
Described accumulation of heat heat generating fiber, for coffee carbon fiber, belongs to modified dacron, is by discarded coffee grounds, through 1300
The coffee carbon that DEG C high temperature carbonization generates, uses nanotechnology to carry out micronization, grinds to form the nanometer grade powder ultra micro of 300nm
Grain, then made by co-blended spinning with polyester；Selected coffee carbon fiber dimensious is 1.67dtex × 38mm, and coffee carbon fiber mixes
It is 30%～50% by ratio；
Described regenerated celulose fibre, selection viscose rayon (or Modal etc.), fiber dimensious is (1.33～1.67)
Dtex × 38mm, on the premise of ensureing that final products have soft comfortable, can reduce again cost, and its mixed ratio exists
30%～50%；
Described high shrinkage acrylic, specification is 1.67dtex × 38mm, intensity 3.5cN/dtex, decatize percent thermal shrinkage 27%,
90 DEG C～100 DEG C of hot water shrinkages 28%, high shrinkage acrylic blending rate is 10%～30%；
Described water soluble vinylon chopped fiber, specification is 1.67dtex × 38mm, and 80 DEG C of water temperatures are dissolved, and blending ratio controls
10%～20%；
(2) selection of yams
The yarn that the warming woven fabric of the present invention uses, warp thread is accumulation of heat heat generating fiber/regenerated celulose fibre mixed yarn,
The blending ratio of accumulation of heat heat generating fiber (coffee carbon fiber) is 30～50%, and the blending ratio of regenerated celulose fibre (Modal) is 70
～50%；
Weft yarn 1 is accumulation of heat heat generating fiber/regenerated celulose fibre mixed yarn, mixing of accumulation of heat heat generating fiber (coffee carbon fiber)
Spinning ratio for 30～50%, the blending ratio of regenerated celulose fibre (Modal) is 70～50%；
Weft yarn 2 is that accumulation of heat heat generating fiber/regenerated celulose fibre/high shrinkage acrylic/water soluble vinylon four-in-one blending is swollen
Body double-decker yarn, the blending ratio of accumulation of heat heat generating fiber (coffee carbon fiber) is 30～50%, regenerated celulose fibre (not generation
You) blending ratio be 30～50%, the blending ratio of high shrinkage acrylic is 10～30%, the blending ratio of water soluble vinylon be 10～
20%；
(3) design of the accumulation of heat heating varicosity warming woven fabric of double-decker yarn
1, specifications design
For having certain conformal, warmth retention property after making fabric dress, stretching convenient, comfortable ventilating, design specification is 28tex
× 28tex × 354 piece/10cm × 276 piece/10cm, door width is 146cm, uses filling-backed weave, and grammes per square metre is 170g/m2；Design
Filling density is unsuitable excessive, too conference extruding four-in-one blending buiky yarn hollow space, makes yarn reduce with the volume of fabric, reduces and store
Effect of fever fiber, therefore select 270～280/10cm；
2, organization design
Fabric tissue uses filling-backed weave, and yarn is shape configuration in an overlapping in fabric, forms reversible cloth, relatively fine yarn
Thickness and the quality of fabric, the most frivolous comfortable raising thermal property can be increased；
Weft yarn configuration instruction is as follows: the 1st kind of warming woven fabric: table latitude: weft yarn 1；Back weft: weft yarn 2；2nd kind of warming machine
Knitted fabric: table latitude: weft yarn 2；Back weft: weft yarn 2；
The table latitude of the 1st kind of fabric uses weft yarn 1, and back weft uses weft yarn 2；The table latitude of the 2nd kind of fabric and back weft all use latitude
Yarn 2；The tissue of two kinds of fabrics in table 1 is identical: table organization uses 2/2, and inner tissue employing 3/1, backing texture is then 1/3
, the exterior and the interior weft yarn arrangement ratio is 2: 2, the most either the 1st kind of fabric or the 2nd kind of fabric, owing to back weft is four component accumulation of heats
Warming yarn, makes fabric and direct skin contact mask have good comfortableness because of filling face effect；The latitude flotation line of table latitude is necessary
Being covered in by the latitude interlacing point of back weft, the short latitude of back weft floats long line and is arranged in the two of neighboar lists latitude and floats between long line；
(4) the woven fabric technological process of production
Weft yarn 2 is containing high shrinkage acrylic and water soluble vinylon, according to moving back dimension (water soluble vinylon in stripping yarn) and knitting
The priority made, woven fabric produces and moves back dimension before having weaving, retreating of weaving ties up two kinds of technological processes:
1, move back dimension reeled yarn before weaving and move back dimension
1st kind of fabric employs, due to table latitude, the weft yarn that percent thermal shrinkage is different from back weft, it is therefore necessary to use reeled yarn to move back dimension
Method, technological process is as follows:
(1) warp end preparing: cheese → warping → sizing → pass；
(2) weft preparing: 1. weft yarn 1: cheese；
2. weft yarn 2: cheese → reeling skeining → move back dimension (simultaneously carrying out hot water expanding treatment) → cleaning → drying → network
Cylinder；
(3) woven fabric produces: weaving → dyeing and finishing；
2, the dimensional fabric that retreats of weaving moves back dimension
Fabric moves back the feature of dimension technological process: technological process is short, low cost, but moves back dimension, desizing, high receipts after being made into cloth again
Contracting acrylon thermal contraction, can affect the shaping of final fabric, and the style of woven fabric is the most variant, therefore in weaving and dye
This factor is must take into during whole technique；
2nd kind of fabric employs the identical weft yarn of percent thermal shrinkage 2 due to table latitude with back weft, and fabric therefore can be used to move back dimension
Method, technological process is as follows:

Accompanying drawing explanation
Fig. 1 is the accumulation of heat heating varicosity double-decker yarn schematic diagram of the present invention；
Fig. 2 is filling-backed weave looming draft in the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
One, the accumulation of heat heating warming mechanism of the varicosity warming woven fabric of double-decker yarn and feature
(1) the warming mechanism of the accumulation of heat heating varicosity warming woven fabric of double-decker yarn
1, the formation mechenism of accumulation of heat heating varicosity double-decker yarn
Yarn population structure used by the present invention is varicosity double-decker hollow yams.
First it is spinning, by short to accumulation of heat heat generating fiber, regenerated celulose fibre, water soluble vinylon, high shrinkage acrylic four kinds
Fiber blend resultant yarn.
Next to that move back dimension with expanded, by above-mentioned four-in-one mixed yarn through hot water treatment, dissolve water soluble vinylon, simultaneously because of
High shrinkage acrylic also produces irreversible thermal contraction, produces bulking effect, causes the axial contraction in length of yarn, and other fibers produce
Expanding curling, make to produce in the middle part of yarn hollow, obtained double-decker yarn, the cross section structure of final yarns is as it is shown in figure 1,1
For high shrinkage acrylic, 2 is accumulation of heat heat generating fiber, regenerated celulose fibre, and 3 is the hollow space of yarn.Due to high shrinkage acrylic
Itself forms yarn core, and therefore it also undertakes certain strength.
The formation of the hollow space of double-decker yarn, actually has two aspects: on the one hand be because using hot water dissolving
Water soluble vinylon of having decorporated is formed；On the other hand, during being because hot water treatment, high shrinkage acrylic produces irreversible heat
The percent thermal shrinkage that shrinkage factor ＞ outsourcing chopped fiber produces, thus on the basis of original hollow, add again bulkiness and hollow
Degree.
2, the warming mechanism of the accumulation of heat heating varicosity warming woven fabric of double-decker yarn
The warming Basic Mechanism of warming woven fabric is to utilize air layer clamped by top layer and nexine, improves warming effect.
The tissue of this kind fabric commonly uses double-layered structure, re-organized, and double-layered structure is used for producing two-layer fabric, and re-organized is used for producing two-sided
Fabric, the fabric tissue of the woven thermal fabric that the present invention is produced uses filling-backed weave, and its surface texture is 2/2, instead
Covering weave is 1/3, inner is organized as 3/1, and the exterior and the interior weft yarn arrangement ratio is 2: 2, and its looming draft is as shown in Figure 2.
This woven fabric utilizes the bilateral structure of filling-backed weave so that fabric has certain thickness and weight, improves
The warmth retention property of fabric.If nexine tissue is processed through napping, make clothing and wear next to the skin then that warmth retention property, comfortableness be more preferably.
Two, the accumulation of heat heating design of the varicosity warming woven fabric of double-decker yarn and production method
(1) selection of fibrous raw material
1, accumulation of heat heat generating fiber, is the key fiber raw material of the present invention, has polytype in the market, such as Japan of Japan
Spin the moisture absorption heating Eks fiber of company, Taiwan Hua Maosheng skill limited company and the coffee of Shanghai Defulun Chemical Fiber Co., Ltd.
Coffee Carbon fibe etc..The present invention have selected Shanghai De Fulun coffee carbon fiber as accumulation of heat heat generating fiber, and it belongs to modified dacron,
It is by discarded coffee grounds, through the coffee carbon that 1300 DEG C of high temperature carbonizations generate, uses nanotechnology to carry out micronization, grind to form
The nanometer grade powder ultramicro powder of 300nm, then made by co-blended spinning with polyester.The existing accumulation of heat of coffee carbon fiber, moisture absorption
Heating, far infrared heating heat-preserving function, have again absorption abnormal flavour, effect of natural deodorization, the also spy of polyster fibre high intensity
Point, fiber itself is in black gray expandable.Coffee carbon fiber dimensious selected by the present invention is 1.67dtex × 38mm, the fiber blended ratio of coffee carbon
The selection principle of example is on the premise of ensureing warming effect, takes into account comfortableness and cost, typically 30%～50%, if ratio
Excessive, affect comfortableness, and cost increases；Ratio is too small, can not play again the heat generating and retention effect of coffee carbon fiber.
2, regenerated celulose fibre, has good hygroscopicity, so that product has good comfortableness.Regenerated fiber
Cellulose fiber also has a variety of: such as common viscose glue, lyocell (Lyocell), Modal, bamboo pulp fiber.The present invention selects viscose glue fine
Dimension (Modal), fiber dimensious is (1.33～1.67) dtex × 38mm, before ensureing that final products have soft comfortable
Putting, can reduce again cost, its mixed ratio is 30%～50%.
3, high shrinkage acrylic, at normal temperatures as normal fiber, after high temperature steaming or high-temperature-hot-water process, produces
Irreversible thermal contraction, additionally has good springiness, a feature that intensity is high, as the yarn core of mixed yarn, both can undertake yarn
And the strength of fabric, contraction can be produced after heat treatment again and make other filament expansion thus produce yarn hollow, finally make yarn
Line has warmth retention property and preferable elasticity.The present invention selects to use high-shrinkage acrylic fiber, and specification is 1.67dtex × 38mm, by force
Degree 3.5cN/dtex, decatize percent thermal shrinkage 27%, 90 DEG C～100 DEG C of hot water shrinkages 28%.Because high shrinkage acrylic is through hot water
The yarn core of mixed yarn will be become after process, yarn body section is in center and undertakes strength, because high shrinkage acrylic heat is received
Other fibers of shrinkage ＜, cause other fiber crimps to swell generation hollow double-layer structure, and high shrinkage acrylic blending rate is the biggest,
The bulkiness of final products is the biggest, if adding water soluble vinylon, then high shrinkage acrylic blending rate should suitably reduce.
Because adding water soluble vinylon in the middle of the double-decker yarn of the present invention, therefore high shrinkage acrylic blending rate can suitably reduce one
A bit, select 10%～30%.
4, water soluble vinylon chopped fiber, is characterized under room temperature normally to spin with other fibers, but can when post processing
It is dissolved in hot water, thus forms double-decker yarn.Water soluble vinylon chopped fiber specification is mainly fibre length, line density, water
Solution temperature.Wherein water solubility temperature affects aftertreatment technology, also affects cost of material, and water solubility temperature is high, and post processing is dissolved
Speed is slow, and consumed energy is big, but cost of material is relatively inexpensive；Water solubility temperature is low, and post processing dissolution velocity is fast, and consumed energy is few,
But water soluble vinylon cost of material is high, cost of material is high.Water soluble vinylon chopped fiber specification used by the present invention be 1.67dtex ×
38mm, 80 DEG C of water temperatures are dissolved.Soluble vinylon fiber blending rate is high, and degree of hollowness is high, good warmth retention effect, but cost increases, and
Resultant yarn and fabric intensity decline；Blending rate is low, and cost reduces, and resultant yarn and fabric intensity are preferable, but degree of hollowness is low, warming effect
Decline.Therefore soluble vinylon fiber blending ratio controls 10%～20%.
(2) yams
The yarn that the warming woven fabric of the present invention uses, warp thread is accumulation of heat heat generating fiber/regenerated celulose fibre mixed yarn,
Weft yarn 1 is accumulation of heat heat generating fiber/regenerated celulose fibre mixed yarn, weft yarn 2 be accumulation of heat heat generating fiber/regenerated celulose fibre/
High shrinkage acrylic/water soluble vinylon four-in-one blending varicosity double-decker yarn, yams is shown in Table 1:
The yams that the warming woven fabric of table 1 present invention is used
(3) design of the accumulation of heat heating varicosity warming woven fabric of double-decker yarn
1, specifications design
For having certain conformal, warmth retention property after making fabric dress, stretching convenient, comfortable ventilating, design specification is 28tex
× 28tex × 354 piece/10cm × 276 piece/10cm, door width is 146cm, uses filling-backed weave, and grammes per square metre is 170g/m2.Design
Filling density is unsuitable excessive, too conference extruding four-in-one blending buiky yarn hollow space, makes yarn reduce with the volume of fabric, reduces and store
Effect of fever fiber, therefore select 270～280/10cm to be advisable.
2, organization design
Fabric tissue uses filling-backed weave, and yarn is shape configuration in an overlapping in fabric, forms reversible cloth, relatively fine yarn
Thickness and the quality of fabric, the most frivolous comfortable raising thermal property can be increased.
Being used weft yarn 1 (with the bi-component yarn that warp thread is consistent) from the table latitude of 1: the a kind of fabric of table, back weft uses latitude
Yarn 2 (four component heat accumulation thermal yarns).The table latitude of the 2nd kind of fabric and back weft all use weft yarn 2 (four component heat accumulation thermal yarns).
The tissue of two kinds of fabrics in table 1 is identical: table organization's employing 2/2, inner tissue employing 3/1, and backing texture is then 1/3,
The exterior and the interior weft yarn arrangement ratio is 2: 2, the most either the 1st kind of fabric or the 2nd kind of fabric, owing to back weft is four component heat accumulation thermals
Yarn, makes fabric and direct skin contact mask have good comfortableness because of filling face effect.The latitude flotation line of table latitude must be by inner
The latitude interlacing point of latitude covers in, and the short latitude of back weft floats long line and is arranged in the two of neighboar lists latitude and floats between long line.Its looming draft is shown in Fig. 2
Shown in.
This woven fabric utilizes the bilateral structure of filling-backed weave so that fabric has certain thickness and weight, improves
The warmth retention property of fabric.If nexine tissue is processed through napping, make clothing and wear next to the skin then that warmth retention property, comfortableness be more preferably.
(4) the woven fabric technological process of production
Knowable to table 1 weft yarn configuration instruction, weft yarn 2 is containing high shrinkage acrylic and water soluble vinylon, according to moving back dimension (stripping yarn
Water soluble vinylon in line) and woven priority, woven fabric produces and moves back dimension before having weaving, retreating of weaving ties up two kinds of techniques
Flow process:
1, move back dimension reeled yarn before weaving and move back dimension
Reeled yarn moves back the feature of dimension technological process: technological process length, cost are high, but before weaving, weft yarn just completes
Move back peacekeeping high shrinkage acrylic thermal contraction fixation, beneficially woven fabric to shape.The 1st kind of fabric in table 1 makes with back weft due to table latitude
With the different weft yarn of percent thermal shrinkage, it is therefore necessary to using reeled yarn to move back dimension method, technological process is as follows:
(1) warp end preparing: cheese → warping → sizing → pass；
(2) weft preparing: 1. weft yarn 1: cheese；
2. weft yarn 2: cheese → reeling skeining → move back dimension (simultaneously carrying out hot water expanding treatment) → cleaning → drying → network
Cylinder；
(3) woven fabric produces: weaving → dyeing and finishing.
2, the dimensional fabric that retreats of weaving moves back dimension
Fabric moves back the feature of dimension technological process: technological process is short, low cost, but moves back dimension, desizing, high receipts after being made into cloth again
Contracting acrylon thermal contraction, can affect the shaping of final fabric, and the style of woven fabric is the most variant, therefore in weaving and dye
This factor is must take into during whole technique.The 2nd kind of fabric in table 1 employs, due to table latitude, the latitude that percent thermal shrinkage is identical with back weft
Yarn 2, therefore can use fabric to move back dimension method, and technological process is as follows:
(1) warp end preparing: cheese → warping → sizing → pass
(2) weft preparing: cheese
(3) woven fabric produces: weave → move back dimension (simultaneously carrying out hot water expanding treatment) → cleaning → dyeing and finishing
(5) dimension and bulking process are moved back
1, dimension and bulking process principle are moved back
The cheese that cotton mill produces both had contained water soluble vinylon, contained again high shrinkage acrylic, in order to make double-decker
Yarn, it is necessary to carry out moving back peacekeeping expanding treatment.
Moving back dimension technique is exactly rationally to select water temperature, bath raio, time etc., and the basis that dimension technique is moved back in formulation is water soluble vinylon
Solution temperature.The solution temperature of domestic water soluble vinylon 60 DEG C～90 DEG C, the temperature moving back dimension is higher than water soluble vinylon dissolving
Temperature 10～15 DEG C.
While moving back dimension, also carry out expanding treatment with hot water, it may be assumed that make high shrinkage acrylic produce in the hot water irreversible
Thermal contraction, formed yarn core；Other fiber percent thermal shrinkages are the least, produce and curl into outer wrapping fiber, thus make buiky yarn.System
The Main Basis determining bulking process is the vitrification point of acrylon.The vitrification point of acrylon about 90 DEG C, swelling temperature wants height
In acrylon vitrification point 10～20 DEG C.
2, dimension and expanded main technologic parameters are moved back
(1) hot water temperature: 100～105 DEG C, i.e. under normal pressure, boiling water treating.
(2) bath raio: bath raio is less on bulking process impact, has considerable influence to moving back dimension rate.Short liquor ratio water consumption is few, moves back dimension
Rate reduces；Big bath raio water consumption is many, moves back dimension rate and improves.The bath raio being generally used for moving back dimension controls at 1:5～1:20.
(3) hot-water treatment time: in order to take into account hot water expansion effect, it is ensured that higher moves back dimension rate, hot water temperature is the lowest, bath
Ratio is the least, and hot-water treatment time should be the longest, and general hot-water treatment time controls 20～60min.Along with carrying of hot water temperature
High, the increase of bath raio, dissolution time can be gradually shortened.
(6) weaving
1, reeled yarn moves back the weaving of dimension
The 1st kind of woven thermal fabric (ginseng is shown in Table 1) that the present invention is produced, the yarn material of use: warp thread is to store
Fever fiber/regenerated celulose fibre mixed yarn, table latitude is weft yarn 1, identical with warp thread；Back weft is weft yarn 2, is accumulation of heat heating
Fiber/regenerated celulose fibre/high shrinkage acrylic/water-soluble fibre four-in-one blending varicosity double-decker yarn.Due to table latitude
Differ greatly with the percent thermal shrinkage of back weft, therefore, the 1st kind of woven thermal fabric (ginseng is shown in Table 1), it is necessary to use reeled yarn to move back dimension
Weaving, to avoid finished textile product to cause finished product fabric out-of-flatness because of the larger difference of the exterior and the interior layer broadwise dyeing and finishing shrinkage.
(1) warping technology
Bi-component yarn strength is moderate, can suitably strengthen tension in Warping, uses Benniger ZC high-speed chip yarn warping machine, this machine
Being furnished with GCF type yarn tensioner and automatic stop motion, simple to operate, troubleshooting is convenient.Utilize the high-efficient liquid that this machine is furnished with
Pressure brake unit, can accomplish warp beam, pressure roller and cord roller synchronous braking to reach efficiently to brake, the stop time control 0.3～
0.4S, is parked in distance 3～4m.The warp beam circle produced is real, and sheet yarn tension is uniform, and formability is good.Speed is set as 900m/min.
Concurrently set bobbin cradle spindle angle, the most smooth through looking into yarn path, it is ensured that bobbin unwinding is normal, it is to avoid filoplume increases.
(2) slashing technique
Sizing operation uses without PVA environmental protection 2 and the slashing technique of the low rate of sizing.Save the energy, it is achieved to remaining slurry simultaneously
Make full use of.Bi-component yarn surface hairiness is few, and yarn strength has promoted, and the relatively low rate of sizing can realize increasing and rub pliable and tough with serous coat
It it is main, it is to avoid the generation of secondary filoplume.Formula of size: phosphate ester starch 45KG, composite modified starch 25Kg, acrylic acid 5kg, wax
Sheet 2kg, antistatic additive 2kg, size mixing volume 1000L, concentration of slurry 7%, serum viscosity 10s, and a small amount of acrylic size is permissible
Ensure the film property that yarn body is soft and good, be aided with hygroscopic water strand and after waxing is effectively reduced regeneration filoplume and produces.Use ancestral gram
Warp sizing machine, with middle small tension control, reduces warp thread and extends, sizing speed 60m/min, sizing temperature 90 DEG C, squeezing pressure 9.5KN,
The rate of sizing 10.5%, regain 9.5%, enhancing rate 28.5%, subtract the rate of stretching 25%, filoplume reduction rate 35%.
(3) weaving process
Loom uses field, Tianjin coltfoal--and 9200 air-jet looms, owing to warp thread is bi-component and elastic preferable, this machine shortens beating
Traverse, beating is fully；While keeping opening amount, make heald frame near fell, enlarged openings angle as far as possible, reduce opening not
Good.AJC-S wefting insertion automatically controls: configuration can save gas mode capabilities, it addition, matched by the weft yarn flight controlled with reality
Nozzle sprays, and enables province's gas and steady running to get both；Two kinds of weft yarn thicknesses are consistent, reasonable adjusting major-minor nozzle wefting insertion air pressure,
Make weft yarn have the tension force of uniformity, make weft yarn be in micro-tense situation during wefting insertion all the time.Thus, major-minor nozzle draws
Latitude air pressure can not be the highest, and main burner air pressure adjustment is 0.25MPa, and auxiliary nozzle air pressure is adjusted to 0.4MPa, and saves the energy；Rationally
Regulation opening time, if opening time is too late, opening is not enough, and wefting insertion resistance strengthens, and causes wefting insertion failure.Opening time during production
Control is 2950；Suitably increase warp tension, make warp thread have good opening, warp tension device is set to 3.5KN；?
Outlet side installs traction apparatus additional, can reduce spacing between pilot jet, its injecting time of proper extension.
2, fabric moves back the weaving of dimension
The 2nd kind of woven thermal fabric that the present invention is produced, uses fabric to move back the weaving of dimension, the yarn material of use
Ginseng is shown in Table 1, and warp thread is accumulation of heat heat generating fiber/regenerated celulose fibre mixed yarn, and weft yarn 1 and weft yarn 2 are all accumulation of heat heatings
Fiber/regenerated celulose fibre/high shrinkage acrylic/water-soluble fibre four-in-one blending varicosity double-decker yarn, is made into grey cloth
Move back dimension and fabric desizing subsequently, dyeing and finishing etc. more all will to be processed in the hot water, also result in high convergency simultaneously
Acrylon produce bigger, irreversible thermal contraction in the hot water, and grain cross shrinkage factor is relatively big, i.e. dyeing and finishing width shrinkage is relatively big, will
Affect the end count of finished product fabric.
Warp thread is accumulation of heat heat generating fiber/regenerated celulose fibre two component spun-blend, and fiber percent thermal shrinkage is less,
The thermal contraction of its mixed yarn is also little, and therefore after starching, fabric move back dimension, dyeing and finishing processing, fabric warp-wise percent thermal shrinkage becomes
Changing little, the filling density on finished product fabric affects little.
So the weaving that fabric moves back dimension is essentially identical with the weaving that reeled yarn moves back dimension, difference is: in order to
The density making finished product fabric is identical, and reeled yarn moves back dimension and less dyeing and finishing width shrinkage should be used (to be set to w1), fabric moves back dimension and should adopt
(it is set to w by relatively large dyeing and finishing width shrinkage2).If the percent thermal shrinkage of weft yarn is ε, the most in theory: w1=w2×(1-ε).Cause
This is necessary for when Fabric Design considering the dyeing and finishing width shrinkage difference that difference moves back dimension technological process.
