摘要:
The present invention relates to a method for preparing a textile finishing agent based on an eco-friendly, renewable, and biodegradable biopolymer, and, specifically, to a method for preparing a textile finishing agent, comprising the steps of: forming, at room temperature, a solution comprising an organic acid and the balance of a solvent; stirring chitosan and a base solvent in the solution; and preparing a solution in which a mineral material is dissolved.

A new approach for improving fire resistance of cellulosic materials is provided, especially when the cellulosic material is to be used in polymer composites. Cellulosic material is treated with an aqueous mixture of alkali metal or ammonium hydroxide and alkaline earth or aluminum metal salt simultaneously with or within a short period of time of preparing the mixture. The treated cellulosic material becomes self-extinguishing and may also have improved thermal stability, improved interfacial thermal resistance, improved resistance to damage by oxidants and other chemical agents, improved resistance to biological agents and/or improved resistance to damage by ultra-violet light.
摘要:
Disclosed is a method for the production of three-dimensional silk products, wherein a three-dimensional silk product is treated with a silk solvent for a limited period of time so that a partial disintegration of the silk product is obtained whereafter the partially disintegrated silk product is re-stabilised with physical β-sheet induction by a re-stabilising solution.

Disclosed is a method for the production of two- or three-dimensional silk products, wherein a two- or three-dimensional silk product is treated with a silk solvent for a limited period of time so that a partial disintegration of the silk product is obtained whereafter the partially disintegrated silk product is re-stabilised with physical beta-sheet induction.

The invention relates to a method of treating a fabric. It particularly relates to a method of treating a fabric with a rinse product that reduce soil pickup and further ensures that the fabric is cleaner after the subsequent wash. It is thus, an object of the present invention to provide a method of treating a fabric to render the fabrics relatively more hydrophobic and especially to provide a method of treating a fabric during the rinse stage of the fabric cleaning process that reduces subsequent soiling of the fabric during use by the consumer. It has been found that contacting the fabric with a neutral aqueous solution, comprising a water- soluble zinc compound, a deposition aid selected from the group consisting of an amine compound or an amino acid and a soap before drying said fabric, provides the soil repellence to the fabric.

Improvements in the high-temperature wash durability and discoloration levels for fabrics having topically applied silver-ion treatments (such as ion-exchange compounds, like zirconium phosphates, glasses and/or zeolites) are provided. Such solid compounds are generally susceptible to discoloration and, due to the solid nature thereof, are typically easy to remove from topical surface applications, particularly when laundered at elevated temperatures. The inventive treatment requires the presence of a specific cross-linked binder, either as a silver-ion overcoat or as a padded-on component of a cross-linked binder admixed with the silver-ion antimicrobial compound. In addition, specific metal halide additives (preferably substantially free from sodium ions) may be utilized to combat the discolorations typical of such silver-ion formulations. As a result, high-temperature wash durability, discoloration levels, or both, can be improved to the extent that after a substantial number of standard launderings and dryings, the inventive treatment does not wear away in any appreciable amount and the color of the treatment remains substantially the same as when first applied. The particular treatment method, as well as the treated fabrics are also encompassed within this invention.

There are provided wrinkle reducing compositions and method for treating fabrics in order to improve various properties of fabrics, in particular, reduction or removal of unwanted wrinkles, by means of an aqueous composition comprising a nonionic polyhydric alcohol humectant and a water-soluble wetting agent selected from a cationic surfactant, a non-alkoxylated nonionic surfactant and an anionic surfactant.
