J) eventually packing is examined: carry out artificial inspection eventually by the yardage roll after batching, and product all qualified to quality, outward appearance is carried out the water-fastness lining finished product of the packing knitting spandex fabric of formation.
Described step c) in REACTIVE DYES adopt the C type REACTIVE DYES of Ciba Specialty Chemicals, degree of fixation is 90 ~ 98%, described alkali lye adopts sodium hydroxide solution, REACTIVE DYES is mixed in setting ratio 4:1 by proportioning pump with alkali lye, and dye liquor temperature is 25 ~ 30 DEG C, and staining bath capacity is 45L, described low temperature material adopts epoxy novolac type resin, described steps d) in the pick-up about 65%, speed of a motor vehicle 40m/min of padding process, padding pressure is 3 ~ 4kg/cm 2, described step g) and middle employing polyurethane is without powder base slurry as primer layer, and adopt polyamide hot as face glue-line, the order number of described cylinder is CP40, and the aperture of cylinder is 0.29mm, and the thickness of cylinder is 0.18mm.
1, product warp thread latitude employing 50D × 50D low elastic polyester filament is weaved through large circle machine employing groove pin knitting skill and is formed, and cloth cover is closely smooth, high resilience.Groove pin braiding large circle machine has demonstrated and has been better than traditional latch needles large circle machine, and have obvious strong point, it can produce the high-quality cloth cover that the large picture machine of latch needles cannot be produced.(1) as plating-knitted in done with low elastic polyester filament, due to groove pin large circle machine coil do not resemble in latch needles on shank, form coil, therefore on shank without arcuate eminence phenomenon, thus loop construction more closely can be knit out.The fabric coil tightness that the groove pin large circle machine of 20 plane No. weaves can be equally tight with the fabric coil that 28 plane No. latch needles large circle machines weave.(2) another feature of fabric face that multichannel groove pin large circle machine weaves is that coil is more vertical, and the fabric face eliminating the braiding of multichannel latch needles large circle machine often presents helical form and distorts phenomenon, and cloth cover is flat smooth more, high resilience.
2, adopt the cold-rolling heap staining new technology of energy-conserving and environment-protective, selected the C type REACTIVE DYES of the Ciba of high colour-fast rate, in the whole process that dyeing is produced, implement the thought of " energy-saving and emission-reduction, ecological, environmental protective ".Along with the reinforcement of environmental consciousness, more and more higher to the requirement of weaving clothing product, countries in the world all meet Green Textiles and the eco-friendly process for cleanly preparing, particularly dyeing and finishing industry of ecological requirements in research and development.
Cold rolling batch-dying process of the present invention adopts low temperature dyeing, inner for the ease of the abundant infiltrated fiber of dyestuff, will consider selecting of dyestuff from direct, reactive and the several aspect of degree of fixation.Dyestuff need possess that diffusivity is good, permeability is good, alkali resistance is good, and detergency is excellent, color light stabilizing, favorable reproducibility and degree of fixation high.We have selected the C type REACTIVE DYES of Ciba, and it is a kind of REACTIVE DYES being applicable to cold dyeing, and its degree of fixation is up to 90 ~ 98%.
Concrete operations are as follows: after dyestuff and alkali lye being prepared respectively, mixed, add staining bath before dyeing by proportioning pump in setting ratio 4:1.Dissolving dye adopts low temperature material, and dye liquor temperature is at 25 ~ 30 DEG C, and staining bath capacity is in below 50L left and right.In order to dye liquor Rapid Circulation is stablized to keep dye liquor concentration, the method adopting a leaching one to roll is padded, pick-up about 65%, speed of a motor vehicle 40m/min.After base cloth dyeing, clot is stacked in uniform rotation on A cabinet frame, encapsulates yardage roll with Polypropylence Sheet, banks up 12 ~ 15 hours, finally strengthens washing and dries cropping.
3, exploitation is applicable to the property combination that fine powder polyamide hot (PA) is starched without powder base with polyurethane (PU), and products with adhesive intensity is high, protects the feel of fabric.Current clothes are constantly promoting class and range of application, various clothing washing also arises at the historic moment, as heavy ENZYME WASH, frost wash, pickling, sand washing etc., through above-mentioned process clothing can more soft, more smooth, texture is better, simultaneously, many clothes also to carry out in manufacturing process and in the Final finishing of ready-made clothes steam whole scald, also has the fabric of some special treatments in addition, smooth surface, go in the fiber that ordinary hot melten gel is difficult to infiltrate into fabric, this just proposes higher, harsher requirement to adhesive lining.
Present invention employs and there is low melting point, the property combination that the fine powder polyamide hot (PA) with special molecular structure that high melting means is specifically designed to two point base slurry is starched without powder base with polyurethane (PU), compared with the system of other type, there is excellent combination property, to be polyurethane lose without powder base slurry produced by hydrogen bond action in Polyurethane molecule crosslinked to its main cause after being heated, be heated and become the viscous fluid of melting, original physical property is recovered again after cooling, it and upper strata PA hot melt adhesive all have excellent elasticity and intensity, and the fine powder polyamide hot melt of special molecular structure has stronger permeability after drawing melting.Both affinity is better, completely can become to be integrated, while tack temperature lower resistance to various washing again, meet the user needs higher to peel strength, washing fastness requirement, be applicable to the fabric of various fiber, catered to current top grade, diversified market demand.
Above-described embodiment is to explanation of the present invention, is not limitation of the invention, anyly all belongs to protection scope of the present invention to the scheme after simple transformation of the present invention.
