A method for manufacturing fabric with flat screen and digital printed patterns includes: singeing, pretreatment, flat screen scraping sizing, drying, pattern printing, humidification, steaming treatment, washing, and non-ironing and soft setting. The pretreatment is a biological enzyme pretreatment process including: cloth feeding at 75° C., dipping, scouring and bleaching in a working fluid, heating to 90° C. for treatment of 30 minutes, draining, hot water washing and cold water washing. A shortened process flow can be realized, and the positioned sizing that uses a flat screen to scrape a sizing agent to a pattern position to be digital spray-printed on instead of traditional full-width sizing for sizing and printing, which greatly reduces the amount of sizing agent used, lowers production cost and reduces waste water pollution, and solves problem that the fabric is mottled caused by the application of sizing agent in areas without printed pattern due to full-width sizing.

A method for manufacturing a fastener stringer according to the present invention, include a dyeing step for dyeing a fastener stringer including an element row fixed to a side edge portion of a tape made of fiber, a dye cleaning step for removing excess dye from the fastener stringer, a water repellent treatment step for adhering a non-fluorine-based water repellent agent to the fastener stringer, and a pre-dyeing degreasing step for degreasing oil and fat adhered to the fastener stringer by a wet process.

A method for degumming bast fibers comprising soaking a source of bast fiber in a saline solution. The source of bast fiber may be soaked in a saline solution having a concentration ranging between less than 1 part per thousand to about 200 parts per thousand. The saline concentration may vary as the source of bast fiber is soaking, or by alternating bast fiber between aqueous solutions of differing ionic concentrations. In one embodiment, the source of bast fiber is soaked in seawater, wherein the saline concentration varies by alternating the salinity using a tide. The source of bast fiber may be hemp.

The present invention introduces natural and environmentally acceptable (friendly) chemical compositions for fire-fighting liquids and additives, as well as additives for enhanced oil recovery, oil & gas operation facilities and ships, oil refineries and petrochemical industry, drilling and drilling operations, corrosion protection, de-scaling and scaling prevention, cleaning of raw wool, cotton, textile and fabrics, general industrial cleaning and paint/coating removal, leather, fur and skin industries, sewage and effluent treatment, agriculture, meat, fish and poultry industries, olive oil, vegetable oils, and fruit juice industries, health and beauty and pharmaceutical industries, microbial control and insecticide/biocide, soil remediation, and heat and energy conducting fluids.

The present invention relates generally to compositions and methods for oxidizing or discoloring garments, such as denim. Another aspect relates to providing a cost-effective and environmentally safe alternative to hazardous bleaching agents, such as potassium permanganate.

Methods and devices for providing moisture in an ozonation process applied to textile products. Unlike other existing moistening methods the invention relates to process of moistening which is provided by means of spraying water by an ultrasonic atomizer and supplying into enclosed volume in micro droplets and production of super oxide radicals with O.sub.3.

Disclosed are compositions and methods relating to variant maltohexaose-forming alpha-amylases. The variant alpha-amylases are useful, for example, for starch liquefaction and saccharification, for cleaning starchy stains in laundry, dishwashing, and other applications, for textile processing (e.g., desizing), in animal feed for improving digestibility, and for baking and brewing.

A method of manufacturing an elastic fabric including a latent crimped yarn according to an embodiment includes forming a raw fabric by knitting the latent crimped yarn and a polyester yarn, reducing the raw fabric, removing oil from the raw fabric, removing wrinkles of the raw fabric, followed by drying, dyeing the raw fabric, and removing wrinkles of the raw fabric, followed by drying to form the elastic fabric. The method can manufacture a highly elastic fabric having excellent recovery and color fastness to washing.
