The present disclosure discloses a pad-steam bleaching method based on a TBLC-activated hydrogen peroxide system, and belongs to the field of pretreatment processing of textiles. According to the pad-steam bleaching method based on the TBLC-activated hydrogen peroxide system, TBCC and H.sub.2O.sub.2 are compounded with a weak base to prepare a TBCC/H.sub.2O.sub.2/weak base system for performing near-neutral bleaching on cotton fabrics; the fabrics are padded and then steamed to be bleached. By the method disclosed by the present disclosure, the whiteness of fabric treated for 2 minutes by a TBCC/H.sub.2O.sub.2/sodium citrate padding and steaming system is significantly superior to that of fabric treated for 60 minutes by an H.sub.2O.sub.2/NaOH dip bleaching system. The CIE whiteness of the fabric reaches 77 and above, the fabric wettability after treatment is also improved, the damage of the fabric is smaller, and the amount of water used by the method is small. The fabric only needs to have a certain wet pick-up, and a large amount of fabric can be treated by a certain volume of solution, which effectively reduces waste water treatment, saves energy and protects the environment; the method requires a short treatment time and has high bleaching efficiency.

Disclosed are processes for manufacturing cross-linked cellulosic fibers and tissue products comprising cross-linked cellulosic fibers, manufactured by reacting an oxidized polyol, in particular, an oxidized sugar having at least two aldehyde groups with a plurality of cellulosic fibers to yield treated fibers and heating the treated fibers at a temperature greater than about 140? C. to cure the treated fibers. In particular, said sugar is sucrose and the oxidising agent comprises hydrogen peroxide. The instant cross-linked fibers are manufactured without well-known cross-linking agents such as formaldehyde or polycarboxylic acids, and have good brightness and color and resist yellowing. Furthermore, the cross-linked cellulosic fibers are generally free from off odors and the instant cross-linked cellulosic fibers have enhanced properties, such as improved wet bulk, compared to uncross-linked fibers.

A manufacturing method for functionalized dyed textile, where the textile is preferably a textile or a knit, including the following steps: getting a dyed textile having a majority by mass of natural fibers, preferably cellulose fibers; bleaching of the dyed textile in order to get a bleached dyed textile whose dye has not been altered; and chemical functionalizing of the bleached dyed textile in order to get a hydrophobic dyed textile, where the functionalization has an increased attachment to the dyed textile because of the prior bleaching. Also, a functionalized dyed textile and the use of a bleaching solution for increasing the hold on the dyed textile of the chemical functionalization.

Embodiments relate generally to methods and systems for bleaching textiles using ozone gas that incorporates a color removal step. In one example, there is provided a hybrid machine that incorporates certain features of a washer, but that also includes an integrated blower for gas distribution inside the machine. There is also provided an ozone dosing control system that allows for maintenance of a constant concentration of ozone in the machine. In one embodiment, the ozone output measured in grams/hour at this constant concentration in conjunction with the weight of product measured being treated may be referred to as the bleaching factor. There is further provided a wastewater dye removal step, in which ozone is used to clean the water and remove dyes and other colors that may be deposited via denim or other garments.

A hollow fabric is obtained by providing cotton blended yarns and alkali-soluble polyester yarns which are arranged in a ratio of 10:2 as warp yarns, and providing cotton blended elastic yarns and alkali-soluble polyester filaments which are arranged in a ratio of 6:2 as weft yarns. The warp yarns and weft yarns are interwoven into plain weaves, and the plain weaves are subjected to alkali solution to remove the alkali-soluble polyester filaments, thereby obtaining greige cloth having meshes. The greige is subjected to boiled bleaching, softening and drying to obtain the hollow fabric. By optimizing the ratio of yarns and using a boiled bleaching, softening and drying process, a soft, smooth and fluffy product is produced with humidity-absorbing and breathability characteristics.

Disclosed are processes for manufacturing cross-linked cellulosic fibers, as well as cross-linked fibers prepared by the same and tissue products comprising the novel cross-linked cellulosic fibers. The cross-linked fibers are manufactured by reacting an oxidized sugar having at least two aldehyde groups with a plurality of cellulosic fibers to yield treated fibers and heating the treated fibers at a temperature greater than about 140? C. to cure the treated fibers. The instant cross-linked fibers are manufactured without well-known cross-linking agents such as formaldehyde or polycarboxylic acids. As such the present cross-linked cellulosic fibers have good brightness and color and resist yellowing. Further, the cross-linked cellulosic fibers are generally free from off odors. Like prior art cross-linked fibers however, the instant cross-linked cellulosic fibers have enhanced properties, such as improved wet bulk, compared to uncross-linked fibers.
