Description
Technical field:
The present invention relates to the dyeing and finishing production technical field of polyester-cotton blend anti-fluffing and anti-pilling fabric panel.
Background technology:
Durable owing to having, wide, the quick-drying washable and snugness of fit of polyester/cotton blended fabric and as the first-selection of garment material, but due to fabric itself and be subject to extraneous rubbing action, produce pilling phenomenon, affect outward appearance and wearability.
According to interrelated data introduction, cause and the influence factor of polyester-cotton fabric generation pilling are specific as follows:
(1), polyester-cotton fabric produces the reason of pilling:
1., fluffing: in the time that fabric is subject to extraneous friction in process and clothes wearing process, if when frictional force is greater than frictional force between fiber strength or fiber or cohesive force, fiber ends will be drawn out and form ring and fine hair, fabric face generates fine hair.
2., balling-up: the fiber in fabric is in the time of stressed friction, slippage, its one end is imbedded in the fiber of fabric, the other end stretches out cloth cover, and when fine hair exposes after certain length, the fine hair between certain distance tangles balling-up because rubbing friction, Electrostatic Absorption, cyclic extension and retraction.
3., come off: after the bobbles of fabric face forms, due to differences such as different fibrous fracture intensity differences, yarn twist, fabric constructions, after some bobbles form, very easily come off, and some difficult drop-offs, tangle mutually, add Electrostatic Absorption, affect appearance of fabrics.
(2), affect the factor of pilling:
1., the factor of fiber
Any staple fibre all can balling-up, and the balling-up of terylene short fiber is the most serious.This is mainly because the brute force of terylene and anti-curve performance can be high, makes the ball forming be difficult for coming off from fiber, and the static of terylene is easy to adsorb foreign particles and produces balling-up.In general, cellulose fibre is difficult for pilling.
Fiber is thinner, and the fiber ends that is exposed to yam surface is just more, and the flexibility of fiber is just better, also just tangles more easily balling-up.Comparatively speaking compared with staple fibre than long fiber pilling easily because staple fibre tip is more, frictional force and cohesive force between long fiber are larger, fiber be also just difficult to slippage to fabric face form pilling.
2., the factor of yarn
Yarn is mainly reflected in the impact of fabric pilling in brute force, flexing resistance and the ABRASION RESISTANCE of the twist, surface smoothness, yarn of yarn.Yam surface is bright and clean, fine hair is few, and pilling is just few.The brute force of yarn and bending rigidity height are difficult for balling-up, but the fiber that anti-alternating bending ability is high, abrasive resistance is strong, difficult drop-off after friction balling-up.
3., the factor of fabric
The institutional framework of fabric is also larger on the pilling impact of fabric.Affected by the several respects such as kind, the tightness degree of institutional framework and the surface smoothness of fabric of fabric.Knit fabric construction is more loose, compares the easy pilling of woven fabric.Same class fabric, pilling more easily of institutional framework.Institutional framework difference, the different pillings of surface smoothness are also different, and the easy pilling of fabric of surface irregularity, as jacquard fabric, rib fabric easily produce pilling phenomenon comparatively speaking.BLENDED FABRIC more easily produces pilling phenomenon than simple a kind of fibrous fabric.
4., the factor of processing
Pilling situation is associated with physics, electrochemical conditions such as the frictional force, tension force and the dyestuff that are subject in yarn and fabric Ge road manufacturing procedure, auxiliary agent, dyeing and finishing technologies.Manufacturing procedure is longer, and suffered frictional force, tension force are larger, and the chemical action time is also longer, and fiber ends is just got over easy glide and out produced pilling.
5. the factor of, taking
The function difference of clothes, it is very large that pilling situation difference.In general, taking in process, as larger in the friction being stood, its pilling phenomenon is also just more serious, the only all clothes of some special industry.
Widely know in the industry still there is no at present best solution both at home and abroad although above-mentioned polyester-cotton fabric produces cause and the influence factor of pilling, and along with the integrating with of American-European textile standards, also more and more higher to the requirement of product.

Technological process: enter 90 DEG C of washing → 1 lattice cold wash of cloth → pad alkali working solution (two soak two rolls) → 100 DEG C of * 60min decatize → 4 lattice → pad H
2o
2dEG C * 50-60min decatize → 5 lattice 90 DEG C of washings in working solution → 100 are dried
Roll alkali technology preparation:
Roll H
2o
2prescription:
Polyester-cotton fabric is in the situation that high temperature is long-time and high-alkali, and fabric face can produce " peeling " phenomenon, is similar to spot, can reduce interfibrous slippage, is conducive to improve anti-fluffing and anti-pilling performance, but needs to take into account grammes per square metre, the brute force of fabric simultaneously.Reinforcement fabric moves back and boil, floats refining process can also remove grey cloth spreading mass and oil preferably.Further improve dyefastness and the non-ironing effect of rear arrangement.
2.3 2 operations of singing:
Process conditions: two positive two anti-* 110 ms/min, the rank of singing 4-5 level.
Polyester-cotton fabric floats after destarch and bleaching through flat, due to mechanical friction and the filoplume originally being adhered to by slurry can again discharge, secondary is singed and can further be removed the surface hairiness on fabric, improves more anti-fluffing and anti-pilling performance.
2.4 shaping process:
Process conditions: 220-225 DEG C of * 40m/min* expanding 157cm
Polyester-cotton fabric is through the motion aggravation of heat setting polyster fibre macromolecular chain segment, and the little fusing point of crystal is compared with low and melting occurs, and the size that crystal is large increases, and perfection of crystal and fusing point are improved.Simultaneously, because of the adjustment of molecule segment position, in fiber, internal stress declines, and DIMENSIONAL STABILITY improves, and other performances also have respective change, as Wet-resilient can and pilling performance be all greatly increased, feel is comparatively stiffening.The tension force of breaking ductility during with heat setting strengthens and reduces, and the variation of intensity is little.
2.5 mercerizing process:
Technological process: enter cloth → pad 260-280g/l (straight roller mercerising soak roll 70-90 second) → cloth gripper expanding 159-160cm more more, 5 punchings 5 are inhaled, rush alkali concn 35-50g/l, rush 90 DEG C of washings of the straight roller lixiviating of alkali temperature 80-90 DEG C → bis-lattice * 85-90 DEG C → 5 lattice and dry
Adopt high concentration alkali to polyester-mixed cotton cloth mercerising, can improve appearance of fabrics fineness, flatness, improve dyeing cloth cover, the coefficient of friction while reducing fabric to fabric friction, to a certain degree improves anti-fluffing and anti-pilling effect.Lower machine testing pH value, brute force, grammes per square metre, anti-fluffing and anti-pilling.
2.6 pad dyeing operations:
Technological process: enter dye liquor → infrared preliminary drying → 100-110 DEG C of preliminary drying chamber preliminary drying of cloth → pad → dry → bake 205 DEG C～210 DEG C × 2.5～3 minutes → reduction decatize, caustic soda sodium hydrosulfite consumption is dried according to dye dosage → 100 DEG C × 2.5～3 minutes → 5 lattice cold wash (the 5th lattice oxidation H2O22～3g/l) → more than 95 DEG C soap boiling (soap lye 5g/l, soda ash 5g/l) → 95 DEG C of above 4 lattice washings; Speed of a motor vehicle 35-40 m/min
Production requirement: stable process conditions, adding of each color additive all adopts material cylinder and shower pipe, for ensureing the soaping fastness index of 95 DEG C of finished products, soap boiling and washing temperature condition must strict guarantee more than 95 DEG C, and select clay or nanometer class soaping agent fully to remove the loose colour not anchoring on fiber.In addition, the type selecting of dyestuff is even more important, and facts have proved that two bath raioes one are bathed anti-fluffing and anti-pilling performance poor, is mainly that the mechanical friction of equipment produces static when causing and rubbing, as bristle roller (solve cloth hair white point with) and tension bracket, plaiting apparatus etc.Dye if desired in working solution and can add appropriate smooth agent.
The arranging process of 2.7 no-ironing resins and anti-fluffing and anti-pilling agent combination solution:
Technological process: padding machine pads resin composite dressing liquid → → 100 DEG C oven dry → 160-165 DEG C of bake → tentering of * 2-3 minute 153-154cm → preshrunk (or setting machine pads DEG C * 154-155cm → 160-165 DEG C of bake → preshrunk of * 2-3 minute in * 20 seconds of RESIN FINISH liquid → 190);
The technology preparation of combination solution:
The control of production process:
1, control content of formaldehyde lower than taking standard: principal element is that the methylol hydrolysis of resin itself produces formaldehyde, therefore must, according to the QUALITY STANDARD demand of product, select suitable no-ironing resin kind and auxiliary agent, strengthens washing condition.
2, yellowing, look become problem: generally, RESIN FINISH all can cause that yellowing or look to a certain degree become, and strictly controls every technic index, uses suitable catalyst, and look range degree is controlled to minimum.
3, powerful problem: RESIN FINISH all can have certain brute force to decline, will control technological parameter on the one hand well, adds on the one hand the tearing brute force of fiber protective agent protection fabric.
4, select suitable anti-fluffing and anti-pilling agent, its key component is the high molecular polymer of urethane acrylate, the multiple functional group and the active group that itself contain, can with fiber on active group bonding produce cross-linking reaction and physical bond, form at fabric face there is some strength, the reticulated film of washable, soft, good springiness.In textile finishing process, anti-fluffing and anti-pilling agent has good film forming and permeance property, make it can penetrate into the inside of fiber in fabric face film forming, make the crosslinked bonding of fiber and lint form reticular membrane structure, reach the object that reduces pilling to limit it to move.
Finally by being up to the standards, process by finished product step.
