Specific implementation mode
The present invention is further explained in the light of specific embodiments.
One, the warming mechanism and feature of the accumulation of heat fever warming woven fabric of cored two-layered structural yarn line
(1) the warming mechanism of the accumulation of heat fever warming woven fabric of cored two-layered structural yarn line
1, the formation mechenism of accumulation of heat fever cored two-layered structural yarn line
Yarn overall structure used in the present invention is core-spun double-layer structure hollow yarn.Its yarn forming principle and structural principle are such as Shown in Fig. 1, Fig. 2:
First, using chemical-fibres filaments as heart yarn, outer wrapping fiber contains there are three types of staple fiber, i.e. accumulation of heat heat generating fiber, regeneration is fine Cellulose fiber, water soluble vinylon are spun into covering yarn, and cross section structure is as shown in Figure 1,1 is accumulation of heat heat generating fiber, regenerated fiber Cellulose fiber, water soluble vinylon;2 be chemical-fibres filaments.
Secondly, covering yarn is passed through into hot water treatment, dissolves water soluble vinylon, obtained yarn actual cross-section structure such as Fig. 2 Shown, 2 be chemical-fibres filaments, and 3 be accumulation of heat heat generating fiber, regenerated celulose fibre, and 4 be the hollow space of yarn.
The formation of the hollow space of double-layer structure yarn, actually by two aspects:It is because molten with hot water on one side Solution has decorporated what water soluble vinylon was formed;On the other hand be because hot water treatment during, the chemical-fibres filaments itself as core filaments Generate percent thermal shrinkage > outsourcing staple fibers generate percent thermal shrinkage, to increased again on the basis of original hollow bulkiness with Degree of hollowness.
2, the warming mechanism of the accumulation of heat fever warming woven fabric of cored two-layered structural yarn line
The warming Basic Mechanism of warming woven fabric is to improve warming effect using surface layer and air layer clamped by inner layer. The tissue of this kind fabric commonly uses double-layered structure, re-organized, and for producing two-layer fabric, re-organized is two-sided for producing for double-layered structure The fabric tissue of fabric, the woven thermal fabric that the present invention is produced uses filling-backed weave, looming draft as shown in Figure 3.
The two-sided structure of this woven fabric so that the opposing stationary air being clamped in fabric increases, and improves the guarantor of fabric Warm property.
Therefore the accumulation of heat fever warming woven fabric of cored two-layered structural yarn line of the present invention has accumulation of heat heat generating fiber, bilayer Triple heat-preserving functions such as the hollow, reversible cloth of structure yarn interior;If the chemical-fibres filaments as core filaments have hollow, the guarantor There are warming-up knitted fabric the quadruples such as accumulation of heat heat generating fiber, double-layer structure yarn inner hollow, hollow chemical fiber long filament, reversible cloth to protect Heating function, under the premise of not increasing thickness, greatly improve the warming effect of woven fabric.
Two, the design and production method of the accumulation of heat fever warming woven fabric of cored two-layered structural yarn line
(1) selection of fibrous raw material
1, accumulation of heat heat generating fiber is the key fiber raw material of the present invention, and there are many type, such as Japanese Japan currently on the market The moisture absorption heating Eks fibers of spinning company, the coffee of Taiwan Hua Maosheng skills limited liability company and Shanghai Defulun Chemical Fiber Co., Ltd. Coffee Carbon fibe etc..The present invention has selected Shanghai De Fulun coffees Carbon fibe as accumulation of heat heat generating fiber, it belongs to modified dacron, It is the coffee grounds that will be discarded, by the coffee carbon that 1300 DEG C of high temperature carbonizations generate, is micronized, is ground into nanotechnology The nanometer grade powder ultramicro powder of 300nm, then be made up of co-blended spinning with polyester.The existing accumulation of heat of coffee Carbon fibe, moisture absorption Fever, far infrared heating heat-preserving function, and have the effect of absorption peculiar smell, natural deodorization, the also spy of polyester fiber high intensity Point, fiber itself are 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 to take into account comfort and cost under the premise of ensureing warming effect, generally 30%~50%, if ratio It is excessive, comfort is influenced, and cost increases;Ratio is too small, and cannot play the heat generating and retention effect of coffee Carbon fibe.
2, regenerated celulose fibre has good hygroscopicity, to make product have good comfort.Regenerated fiber Cellulose fiber also there are many kinds of:Such as common viscose glue, lyocell (Lyocell), Modal, bamboo pulp fiber.The present invention selects viscose glue fine It ties up (or Modal etc.), fiber dimensious is (1.33~1.67) dtex × 38mm, is ensureing final products with soft comfortable Under the premise of, and cost can be reduced, mixed ratio is 30%~50%.
3, hollow chemical fiber long filament, such as hollow polyester filament or hollow chinlon filament, have hollow warm-keeping is good, elasticity is good, The feature that intensity is high, wearability is good can not only undertake the strength of yarn and fabric but also with warming as the yarn core of covering yarn Property and preferable elasticity.The present invention selects to use hollow chinlon filament, specification to be 2.8tex/12f, intensity 4.6cN/dtex, breaks Split elongation 31%.Because long filament is the yarn core of covering yarn, center is in yarn body section, in order to ensure the strong of covering yarn Degree and cored effect, ratio used in hollow chinlon filament will generally be controlled 5%~25%.
4, water soluble vinylon staple fiber, its main feature is that can normally spin with other fibers under room temperature, but can in post-processing It is dissolved in hot water, to form double-layer structure yarn.Water soluble vinylon staple fiber specification is mainly fibre length, line density, water Solution temperature.Wherein water solubility temperature influences aftertreatment technology, also influences cost of material, and water solubility temperature is high, post-processing dissolving Speed is slow, and consumption energy is big, but cost of material is relatively inexpensive;Water solubility temperature is low, and post-processing solution rate is fast, consumes little energy, But water soluble vinylon cost of material is high, and cost of material is high.Water soluble vinylon staple fiber specification used in the present invention be 1.67dtex × 38mm, 80 DEG C of water temperature dissolvings.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 is reduced, and resultant yarn and fabric intensity are preferable, but degree of hollowness is low, warming effect Decline.Therefore the control of soluble vinylon fiber blending ratio is 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/ The blended core-spun double-layer structure yarn of chemical-fibres filaments/water soluble vinylon four-in-one, yams are shown in Table 1:
Yams used in the 1 warming woven fabric of the present invention of table
(3) design of the accumulation of heat fever warming woven fabric of cored two-layered structural yarn line
1, specifications design
To have certain conformal, warmth retention property after so that fabric is worn, stretching, extension is convenient, comfortable ventilating, design specification 28tex × 28tex × 354 piece/10cm × 276 piece/10cm, door width is 146cm, using filling-backed weave, grammes per square metre 170g/m2.Design Filling density should not be too large, and too conference squeezes the blended covering yarn hollow space of four-in-one, and the volume of yarn and fabric is made to reduce, and reduces and stores The effect of fever fiber, therefore 270~280/10cm is selected to be advisable.
2, organization design
Fabric tissue uses filling-backed weave, and shape configures yarn in an overlapping in the fabric, reversible cloth is formed, compared with fine yarn The thickness and quality of fabric can be increased, both light and comfortable improved thermal property.It is shown in Table 1 weft yarn configuration instruction, the table of the 1st kind of fabric Latitude uses weft yarn 1 (bi-component yarn consistent with warp thread), the outer weft of the 2nd kind of fabric to use (the four component heat accumulation thermal yarns of weft yarn 2 Line), table organization uses 1/3 ↗;Back weft uses weft yarn 2 (four component heat accumulation thermal yarns), inner tissue to use 3/1 ↗, inner tissue Backing texture be then 1/3 ↖, weft yarn arrangement ratio is 1: 1 in table, and fabric positive and negative is made to all have good filling face effect in this way, Either the 1st kind of fabric or the 2nd kind of fabric make fabric since back weft is four component heat accumulation thermal yarns because of filling face effect Face in direct contact with the skin has good comfort.The latitude flotation line of outer weft must cover in the latitude interlacing point of back weft, back weft Short latitude float the configuration of long line and floated between long lines the two of adjacent outer weft.Specifically as shown in Figure 3.
(4) the woven fabric technological process of production
From 1 weft yarn configuration instruction of table it is found that weft yarn 2 contains chemical-fibres filaments and water soluble vinylon, (yarn is stripped according to dimension is moved back In water soluble vinylon) with woven priority, woven fabric production has weaving before move back dimension, weaving retrogressing dimension two kinds of technique streams Journey:
1, dimension is moved back before weaving --- reeled yarn moves back dimension
Reeled yarn moves back the characteristics of dimension technological process:Technological process is long, of high cost, however before weaving, weft yarn just completes Peacekeeping hollow chemical fiber long filament thermal contraction fixation is moved back, woven fabric forming is conducive to.The 1st kind of fabric in table 1 is due to outer weft and back weft The weft yarn that percent thermal shrinkage is different is used, it is therefore necessary to dimension method be moved back using reeled yarn, technological process is as follows:
(1) warp end preparing:Cheese → warping → sizing → drawing-in;
(2) weft preparing:1. weft yarn 1:Cheese;
2. weft yarn 2:Cheese → reeling skeining → moves back dimension → cleaning → drying → winder;
(3) woven fabric produces:Weaving → dyeing and finishing.
2, the retrogressing of weaving is tieed up --- and fabric moves back dimension
Fabric moves back the characteristics of dimension technological process:Technological process is short, at low cost, but is made into cloth and moves back dimension, desizing, chemical fibre again later Long filament is heat-shrinked, and can influence the forming of final fabric, and the style of woven fabric is also variant, therefore in weaving and dyeing and finishing It must take into consideration this factor when technique.The 2nd kind of fabric in table 1 has used the identical weft yarn of percent thermal shrinkage due to outer weft and back weft 2, therefore fabric may be used and move back dimension method, technological process is as follows:
(1) warp end preparing:Cheese → warping → sizing → drawing-in;
(2) weft preparing:Cheese;
(3) woven fabric produces:Weave → move back dimension → dyeing and finishing.
(5) dimension technique is moved back
The cheese of cotton mill production, also contains water soluble vinylon, in order to which the yarn of double-layer structure is made, it is necessary to be moved back Dimension processing.It is exactly to reasonably select water temperature, bath raio, time etc., and the basis for formulating these techniques is water soluble vinylon to move back dimension technique Solution temperature, 60 DEG C~90 DEG C of the solution temperature of domestic water soluble vinylon.
1, hot water temperature:In order to improve dimension rate of moving back, hot water temperature improves 10~15 DEG C than solution temperature.
2, bath raio:Short liquor ratio water consumption is few, moves back the reduction of dimension rate;Big bath raio water consumption is more, moves back the raising of dimension rate.It is generally used for moving back The bath raio of dimension is controlled 1:5~1:20.
3, dissolution time:In order to ensure to move back dimension rate, hot water temperature is lower, bath raio is smaller, and dissolution time should be longer, so The general dissolution time for moving back dimension is controlled in 20~60min.With the raising of hot water temperature, the increase of bath raio, dissolution time can be with It is gradually shortened.
(6) weaving
1, reeled yarn moves back the weaving of dimension
The 1st kind of woven thermal fabric that the present invention is produced, it is necessary to the weaving that dimension is moved back using reeled yarn, the yarn used Raw material 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 is identical as warp thread, weft yarn 2 It is accumulation of heat heat generating fiber/blended core-spun double-layer structure yarn of regenerated celulose fibre/chemical-fibres filaments/water-soluble fibre four-in-one.
(1) warping technology
Bi-component yarn strength is moderate, tension in Warping can be suitably increased, using Benniger ZC high-speed chip yarn warping machines, the machine Easy to operate equipped with GCF types yarn tensioner and automatic stop motion, troubleshooting is convenient.The efficient liquid being furnished with using the machine Press brake apparatus, can accomplish warp beam, pressure roller and cord roller synchronous braking to reach efficient braking, stop time control 0.3~ 0.4S is parked in distance in 3~4m.The warp beam circle of production is real, and piece yarn tension is uniform, and formability is good.Speed is set as 900m/min. Bobbin cradle spindle angle is concurrently set, it is whether smooth through looking into yarn path, ensure that bobbin unwinding is normal, filoplume is avoided to increase.
(2) slashing technique
Sizing operation using no PVA environmental protection 2 and the low rate of sizing slashing technique.It is energy saving simultaneously, it realizes to remaining slurry It makes full use of.Bi-component yarn surface hairiness is few, and yarn strength is promoted, and it is flexible with serous coat that the relatively low rate of sizing can realize that increasing rubs Based on, avoid the generation of secondary filoplume.Formula of size:Phosphate ester starch 45KG, composite modified starch 25Kg, acrylic acid 5kg, wax Piece 2kg, antistatic agent 2kg, volume of sizing mixing 1000L, concentration of slurry 7%, serum viscosity 10s, a small amount of acrylic size can be with Ensure yarn body softness and good film forming, regeneration filoplume can be effectively reduced and generate by being aided with hygroscopic water strand and after waxing.Use ancestral gram Sizing machine is reduced warp thread and is extended with middle small tension control, sizing speed 60m/min, 90 DEG C, squeezing pressure 9.5KN of sizing temperature, The rate of sizing 10.5%, regain 9.5%, enhancing rate 28.5% subtract the rate of stretching 25%, filoplume reduced rate 35%.
(3) weaving process
Loom uses Tianjin field coltfoal -- 9200 air-jet looms, and since warp thread is bi-component, and elasticity is preferably, this machine shortens beating Traverse, beating are abundant;While keeping amount of opening, make heald frame close to fell as far as possible, opening is reduced not in enlarged openings angle It is good.AJC-S wefting insertion automatically controls:Configuration can save gas mode capabilities, in addition, matched with the flight of actual weft yarn by control Nozzle sprays, and province's gas and steady running is enable to get both;Two kinds of weft yarn thicknesses are consistent, rationally adjust major-minor nozzle wefting insertion air pressure, Make weft yarn that there is uniform tension, weft yarn is made to be in micro- tense situation always during wefting insertion.Thus, major-minor nozzle draws Latitude air pressure cannot be too high, and main burner air pressure adjustment is 0.25MPa, and auxiliary nozzle air pressure is adjusted to 0.4MPa, and energy saving;Rationally Opening time is adjusted, if opening time is too late, opening is insufficient, and wefting insertion resistance increases, and wefting insertion is caused to fail.Opening time when production Control is 2950;It is appropriate to increase warp tension, make warp thread that there is good opening, sets warp tension device to 3.5KN;? Outlet side installs draft gear additional, can reduce the gauge between pilot jet, its injecting time is appropriately extended.
2, fabric moves back the weaving of dimension
The 2nd kind of woven thermal fabric that the present invention is produced, the weaving of dimension is moved back using fabric, the yarn material used 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 is accumulation of heat fever with weft yarn 2 Fiber/blended core-spun double-layer structure the yarn of regenerated celulose fibre/chemical-fibres filaments/water-soluble fibre four-in-one, be made into fabric with Moving back dimension and subsequent fabric desizing, dyeing and finishing etc. again afterwards will all be processed in the hot water, while also result in chemical-fibres filaments Larger, irreversible thermal contraction is generated in the hot water, and grain cross shrinking percentage is larger, i.e., dyeing and finishing width shrinkage is larger, will influence Finished fabric through close.
Warp thread is two component spun-blend of accumulation of heat heat generating fiber/regenerated celulose fibre, and fiber percent thermal shrinkage is smaller, The thermal contraction of its mixed yarn is also little, therefore after starching, fabric move back dimension, dyeing and finishing processing, fabric warp-wise percent thermal shrinkage becomes Change less, the filling density of finished fabric is influenced little.
So the weaving that fabric moves back the weaving of dimension and reeled yarn moves back dimension is essentially identical, the difference is that:In order to Keep the density of finished fabric identical, reeled yarn, which moves back dimension, (to be set as w using smaller dyeing and finishing width shrinkage1), fabric moves back dimension and should adopt (it is set as w with relatively large dyeing and finishing width shrinkage2).If the percent thermal shrinkage of weft yarn is ε, theoretically:w1=w2×(1-ε).Cause This just must take into consideration the different dyeing and finishing width shrinkage differences for moving back dimension technological process in Fabric Design.
