摘要:
A washed down fabric article and a process for treating a fabric article for producing the washed or faded effect is disclosed. The process may include fixing a dye onto the fabric article, discharging a portion of the dye with non-abrasive tumbling elements that includes a bleaching agent. The process further comprises neutralizing the bleaching agent with a neutralizer, and stabilizing the final color of the fabric article.
摘要:
The invention relates to a new laccase from rumen, namely the RL5 laccase. In particular, the invention relates to a polypeptide comprising the amino acid sequence shown in Figure 11 and comprising at least the amino acids No. 80 to No. 150 of the amino acid sequence shown in Figure 11, respectively. The invention also relates to the use of polypeptides further comprising the amino acid sequence of a DUF152 domain with a core sequence as shown in Figure 18 as laccases. Furthermore, the invention relates to methods for producing inventive polypeptides and their use.
摘要:
A discontinuous dyeing or discoloring process for fabrics during which the fabric is moved forward in a preset direction, placed in a water bath and wrung in order to remove a specific amount of water, which varies according to the desired aesthetic effect. The wrung fabric is then coated with a dyeing or discoloring agent in powder and sprayed with water according to a preset distribution pattern. The fabric is then exposed to a heat source to allow the remaining water to evaporate.

The process according to the invention consists in applying printing pastes containing high concentrations of anti-felting polyurethane resins, possibly colored via pigments or other dyeing substances of different dyeing nature (acid, premetallized, reactive, direct, basic and disperse dyes), in combination with traditional printing pastes, colored or not. It is also possible to combine printed design patterns with anti-felting characteristics and printed design patterns obtained with resist printing and/or corrosion printing, as well as to obtain the superimposition of two or more design patterns, of which at least one defined by the shape of unfelted areas. The effect deriving by the contrast of differently felted areas is activated further to the milling step carried out after the printing step.

摘要:
A layered composition which includes a hardened core comprising at least about 50 weight percent permanganate and an outer layer selected from the group consisting of a permeable hydrated cement which will adhere to the core and hardened Mg(OH)₂ which composition releases permanganate ions into an aqueous media over time is described. A method of making and using the composition of the invention also are described.
摘要:
Compositions aqueuses et procédés permettant d'obtenir un effet "délavé", fatigué ou "plus que servi" sur des habits notamment sur les pans et le long des coutures de pantalons et vestes de jean, n'ayant recours ni à des compositions délavantes ni à une usure du tissu par frottement mécanique. En effet, le procédé et la composition que décrit l'invention pour obtenir l'effet fatigué, "délavé" ou "lavage à l'acide" n'utilisent pas de compositions à pierre ponce naturelle ou à agent décolorant. Le traitement se déroule dans de grandes machines à laver de taille industrielle et repose sur la seule action chimique de compositions aqueuses de traitement. Ces compositions aqueuses de traitement sont à base soit de concentrés liquides soit de concentrés solides.
摘要:
Methods for producing a pattern on denim products are disclosed. Patterns may be drawn with either a bleach inhibiting agent or a bleach promoting agent in the forms of a solution or paste. In case the pattern is drawn with a bleach inhibiting agent, the denim product is subjected to bleaching by scrubbing in a rotating drum with a plurality of pumices impregnated with a bleaching solution, such as, calcium hypochlorite; or bleaching by immersion and agitation in a bleaching solution. The pattern may remain in dark blue in contrast with the the other portions. In case the pattern is drawn with a bleach promoting agent, the denim product is immersed and agitated in a bleaching solution; and the pattern may be produced as the portion where the pattern was drawn is decolorized faster than the other portions.

摘要:
A viscous printing paste (23) is imprinted on a reverse surface (21) of a foundation fabric (16) of a surface-type fastener (15a), and then the paste (23) while being viscous is drawn by a suction force to penetrate the foundation fabric (16) from the reverse surface (21) to an obverse surface (18) from which a multiplicity of interlocking elements (17) project. Upon setting of the printing paste (21), a distinctive mark is produced on the obverse surface (18) of the foundation fabric (18). With the foregoing processing steps, a large mark can be provided on the surface-type fastener without effecting negative influence on the shape and function of the interlocking elements.
