The present invention is characterized in that in the baking process, baking temperature is controlled between 150 DEG C and 180 DEG C, baking time is from 2 minutes to 3 minutes, and the baking process is continuously carried out in a heat-shaping stenter. A shaping machine which is 24M long is divided into 8 box regions, wherein a baking region ranges from the first box to the third box, a shaping region ranges from the fourth box to the seventh box, and the technical time of the shaping region is 40s. The present invention and products have the advantages of soft and smooth hand feeling, super strong shrink-proof and wrinkle-proof capacity, no deformation after washing for 20 times, good product reliability and stability, simple process, high operability, low cost and high yield, so the present invention is appreciated by some famous clothing.
Description
One, technical field:
The present invention relates to a kind of dyeing and finishing technology of fabric, a kind of shrinkproof, crease-resistant, non-deforming cotton knitted shell-fabric dyeing and finishing process is particularly disclosed, be applied to produce shrinkproof, crease-resistant, non-deforming cotton knitted shell-fabric, the famous-brand and high-quality garment material of level on steady quality, the quality is provided for the user.
Two, background technology:
Because cellulose fibre has the intensity of good water imbibition, hygroscopicity and feel appropriateness, and chromatophilia, so since ancient times, it is exactly the main material of underwear and shirt, especially natural fabrics such as cotton, fiber crops always have some folding lines and contraction during washing, and people have to tolerating.But the regenerated celulose fibre that 20 beginnings of the century emerged is because its wet strength is low and the contraction in when washing and wrinkle surpass and allow limit, so just begin to address these problems with chemical treatment hardy.
Cotton fiber produces the reason of wash shrinkage, mainly is to relax to shrink and expanded contraction.So-called mitigation is shunk and is meant fabric in process, and the stretching face that is subjected to makes its warp-stretch, is just returned to the phenomenon of original size lentamente by washing.So-called expanded contraction is meant that fiber is met water and expanded, makes the yarn circumference become big, with the yarn that it slightly meets at right angles and contacts, has increased the phenomenon of Len req when crooked.Relax and shrink the loose processing that can pass through in the fabric process, or omit and can remove with continuous compression arrangement in final operation, but aspect the contraction that prevents the expanded generation of yarn, owing to be the person's character of cellulose fibre, so be not easy to prevent.
Thus, with shrinkproof, crease-resistant, indeformable be that the production technology of cotton knitted fabric of main target is anxious to be solved.
Three, summary of the invention:
Technical problem to be solved by this invention provides a kind of shrinkproof, crease-resistant, non-deforming cotton knitted shell-fabric dyeing and finishing process, that the present invention obtains is shrinkproof, crease-resistant, the non-deforming cotton knitted shell-fabric feel is soft, smooth, have extremely strong shrinkproof, crease-resistant ability, gas permeability is good, maximum characteristics be wash 20 times indeformable.The present invention is achieved in that a kind of shrinkproof, crease-resistant, non-deforming cotton knitted shell-fabric dyeing and finishing process, comprise the bad cloth oven dry after dyeing is finished, the clear water that adds regulation in the reactor, add self-control special finishing agent (SDP), constantly stir, and adjusting pH value, treat promptly to begin the starching mangle after the complete reaction, carry out crosslinked again, bake, clean, soft, dehydration, last smooth, soft agent, the tentering HEAT SETTING, check and packing, it is characterized in that: the described technology that bakes, its baking temperature is controlled at 150 °～180 ℃, and the time of baking is 2～3min, pick-up rate: 80～90%, the speed of a motor vehicle: 18m/min, bake technology and carry out continuously in the HEAT SETTING stenter, typing captain 24M is divided into eight case districts, the first oven temperature, degree is controlled at 120 ℃, second the case 150 ℃, the 3rd the case 160 ℃, first case to the three casees is for baking the district, the 4th case to the is for seven the casees shaping area, its oven temperature, degree is 170 ℃, 160 ℃ of the 8th oven temperature, degree, and the shaping area process time is 40s.Now several key technologies in the technology are described below:
(1) preparation of self-control special finishing agent (SDP)
The prescription of SDP and proportioning are urea: glyoxal: formaldehyde (mol ratio)=1: 1: 1.8～2.Earlier urea and glyoxal are dropped in the reaction pot during preparation, stop heating after being warming up to 35 ℃, add soda ash in the stirring, adjusting PH=5～5.5, when being warming up to 45 ℃, opening cooling water control and heat up, when treating that temperature rises to 50 ℃ ± 1 ℃, close cooling water, insulated and stirred 3h adds formaldehyde then.
(2) setting of cross-linking reaction temperature-time
General finishing agent can only be in the amorphous region of fiber or crystal region edge and cellulose hydroxyl Cheng Gongjie crosslinked, the height of control resin's crosslinkage, finishing agent consumption and quality when directly affecting cross-linking reaction, the cross-linking reaction temperature-time is decided to be: 170 ℃, 40s are that the present invention payes attention to what effective grasp of amorphous region in the fibre structure.
(3) baking temperature and time control
Bake is to utilize high-temperature under the condition that has catalyst to exist, adopt chemistry, physics process combined, make fabric construction arrange upright fabric coil again, promote its form stable with the all-moving surface that hinders macromolecular chain segment in the fiber, make special finishing agent in the short period of time with fiber generation cross-linking reaction.Baking temperature is high more, and the time that bakes is short more.When baking temperature during, 1 ℃ of the every rising of temperature at 120 ℃～180 ℃, crosslinked response speed add fast again about.The Wen He condition that bakes too, will cause crosslinked not exclusively, influence the textile finishing effect, but the overgenerous condition that bakes will make fiber impaired, and baking temperature is controlled at 150 ℃～180 ℃, the time of baking is 2～3min, is to solve shrinkproof, crease-resistant, indeformable key.
(4) bake technology
1, pick-up rate: 80～90%
2, the speed of a motor vehicle: 18m/ minute
3, baking technology carries out in the HEAT SETTING stenter continuously, typing captain 24m, be divided into eight case districts, the first oven temperature, degree is controlled at 120 ℃, second the case 150 ℃, the 3rd the case 160 ℃, first case to the three casees is for baking the district, and the 4th case to the is for seven the casees shaping area, and its oven temperature, degree is 170 ℃, 160 ℃ of the 8th oven temperature, degree, the shaping area process time is 40s.
Beneficial effect of the present invention:
Shrinkproof, crease-resistant, the non-deforming cotton knitted shell-fabric that adopt the present invention to produce, feel is soft, smooth, have extremely strong shrinkproof, crease-resistant ability, gas permeability is good, maximum characteristics be wash 20 times indeformable, thereby replaced import, reduce cost greatly, technology can not only guarantee reliability, the stability of product quality, and operating procedure is simple, and is workable, and cost is low, bring notable results.
