摘要:
Procédé pour la fabrication d'une nappe non tissée "spunlace" à base de fibres de coton, qui consiste en continu :
. à faire avancer une nappe (1) à base de fibres de coton, . à entrelacer (2,3) ces fibres à l'aide d'une pluralité de jets d'eau sous pression, . à sécher (8) cette nappe entrelacée, . et enfin, à réceptionner (10) la nappe "spunlace" (9) ainsi obtenue, caractérisé :
en ce que après l'entrelaçage (2,3), et avant le séchage (8), on essore (5) l'eau libre contenue dans la nappe entrelacée (4) ; puis, en ce que on imprègne (6) cette nappe essorée au moyen d'une solution aqueuse d'une résine de polyamide-amine-épichlorhydrine (PAE) à raison, mesurée en produits secs, de 0,2 % à 1 % du poids des fibres de coton ; et en ce que, après avoir exprimé l'excès de solution, on sèche (8) la nappe imprégnée (7), à une température suffisante pour au moins amorcer la réticulation de la résine PAE déposée.
摘要:
A method for the treatment of wool so as to impart shrink resistance comprising, in any order, the steps of:-
i) treating the wool with a proteolytic enzyme, and ii) subjecting the wool to either or both of an oxidative treatment and treatment with a polymer, with the proviso that when the oxidative treatment is used alone it comprises a wet chlorination process. The method may be operated either as essentially a batch process or as a process involving a combination of continuous and batch treatments.
摘要:
Polymers which are capable of self-cross-linking and/or of reacting with cellulose can be used in the treatment of fabric comprising cellulosic fibres to enhance the feeling of comfort when a garment comprising the fabric is worn. The enhanced feeling of comfort is due, at least in part, to an increase in the rate of moisture transport through the fabric. The polymers may be used in conjunction with a liquid or soft solid derivative of a cyclic polyol or of a reduced saccharide resulting from 35 to 100% of the hydroxyl groups in the polyol or the saccharide being esterified or etherified.

摘要:
Substantially nonshedding clean room garments are provided which have a reduced tendency to shed surface particles while retaining good water vapor transmission properties. The garments are comprised of a nonwoven fabric of synthetic fibers which has been coated with from about 2 to about 26 percent of a coating, based on the weight of the uncoated fabric, said amount being sufficient to substantially coat the individual fibers of said fabric on at least one side thereof, without forming a continuous film on the surface of said fabric.
