An activated cotton material and a method for processing cotton to form the activated cotton material are provided. The activated cotton material includes a layer of natural wax that is locked to the surface of cotton fibers by a wax lock.

There is provided a process for chemically pretreating reclaimed cellulose fibres to be used in the production of moulded bodies from regenerated cellulose, wherein the pretreatment includes one stage, in which stage acid metal removal and acid oxidative bleaching are carried out together. Advantages include that the propensity of the regenerated cellulose to clog when flowing in a tube and through a nozzle is reduced. This is believed to be an effect of an efficient metal removal. The need for additional bleaching steps and/or metal removing steps is reduced or even eliminated. A one-stage method is more efficient, faster and less costly compared to a multi-stage method according to the prior art. From an environmental perspective, acidic metal removal is preferred over removal by chelating agents such as EDTA.

A textile structure including one or more layers of warp yarns interwoven with one or more layers of weft yarns, a durable thermoregulating coating, and a binder that chemically bonds the durable thermoregulating coating to the textile structure. The warp yarns and/or weft yarns include polyester yarns. A method for manufacturing a textile structure includes weaving one or more layers of warp yarns with one or more layers or weft yarns to form a woven textile structure, brushing the textile structure at least two times, applying a binder to the textile structure, and applying a durable thermoregulating coating to the textile structure such that the binder chemically bonds the durable thermoregulating coating to the textile structure. The method may also include heat setting and curing the textile structure to fix the durable thermoregulating coating permanently onto the textile structure.

Disclosed is a knitted fabric containing natural fibers and a making method therefor, a liquid ammonia device and a shirt made from the knitted fabric, belonging to the fields of fabrics and clothing. The making method for the knitted fabric containing natural fibers comprises forming yarns containing natural fibers into a knitted fabric by a fabric-knitting method; and performing functional finishing including a liquid ammonia finishing procedure on the knitted fabric. In the liquid ammonia finishing procedure, liquid ammonia impregnation is performed on the knitted fabric at least twice under the condition of mechanical restraint by a guide roller set, thus preventing the knitted fabric from edge curling due to strong shrinkage in the liquid ammonia impregnation process, enabling the knitted fabric to be subjected to sufficient and uniform liquid ammonia impregnation, ensuring the liquid ammonia impregnation effect and controlling the shrinkage rate of the knitted fabric; and through subsequent shaping and finishing procedures, the color stability of the knitted fabric is further improved, the shrinkage rate after washing is reduced, and the crease-resistant performance and resilience performance are improved. The shirt has a low shrinkage rate after washing, good stiffness performance, good resilience performance, color stability, high strength and good crease-resistant performance.

A method for making a burnout fabric includes: (1) pre-treating a greige fabric; (2) processing the pre-treated greige fabric with a burnout paste containing sulfuric acid, synthetic gum tragacanth, and sodium alginate; and (3) post-treating the greige fabric after the burnout treatment to obtain a burnout fabric. The method according to the present invention is simple in process, low in cost, and easy to implement, and the burnout fabric obtained thereby has an attractive and clear pattern, featuring a three-dimensional effect and a high quality.

A bleaching apparatus has an immersing vessel for immersing clothes in a chemical liquid, and a light source for irradiating the clothes immersed in the immersing vessel with light. The chemical liquid may include an oxidizing agent or a reducing agent in a concentration of 3 to 30% owf. The illumination intensity of the light is 10,000 to 70,000 lx.

A device for removing oxidizable stains includes a device body having an opening and an internal space disposed therein. The device body includes a wall that at least partially surrounds the internal space. At least part of the wall is a flexible wall. A frangible wall separates the internal space into a first chamber and a second chamber. One or more solid components are disposed in the first chamber and include an active oxygen component. Water is disposed in the second chamber. A bleach activator component forms part of the one or more solid components or is included with water. The device is configured such that when a force is applied to strain the flexible wall, the frangible wall breaks to allow contact between water and the one or more solid components to form a peracid solution.

The present invention is directed to a method for scouring and increasing the brightness of non-wood fibers. The method comprises forming a mixture of non-wood fibers, exposing the mixture to a scouring liquor and a scouring agent comprising oxygen gas to form a scouring mixture, and scouring the scouring mixture by radially circulating the scouring liquor throughout the scouring mixture to provide scoured fibers.
