Provided are a fluorine-free soil resistant agent and a soil resistant treatment method which give excellent water-repellency and excellent antifouling property to a substrate, especially a carpet. The soil resistant agent contains (1) a fluorine-free copolymer having (a) a repeating unit formed from an acrylic monomer having a hydrocarbon group containing 7 to 40 carbon atoms, and (b) a repeating unit formed from an acrylic monomer having a hydrophilic group, and (2) water or a mixture of water and an organic solvent dispersing the fluorine-free copolymer (1). A method of treating the substrate, includes applying the soil resistant agent to the substrate.

Aspects herein are directed to using a space-treating process to apply functional finishes to a yarn and incorporating the treated yarn into a textile and/or a garment to impart engineered functional properties to the textile and/or garment.

The present invention relates to a textile care product containing a copolymer having N-isopropylacrylamide units, methacrylic acid units and optionally at least one cross-linking agent. The copolymer is used as a soil-release active ingredient, reduces or prevents re-soiling and improves the removal of soiling.

A dustproof fabric which includes an antistatic dustproof fabric having excellent antistatic properties, a high air permeability and high-level dustproof properties is provided. The antistatic dustproof fabric includes two or more fiber layers. At least one of the two or more fiber layers is a first fiber layer which contains a nonionic antistatic agent; and at least one of the two or more fiber layers is a second fiber layer which is electrically charged.

A method of manufacturing an anti-soiling carpet comprises a step of treating a carpet with a liquid solution containing an anti-soiling agent, the anti-soiling agent containing a non-fluorinated polymer () and a non-fluorinated polymer (ii), the non-fluorinated polymer () containing a constituent unit derived from a monomer represented by formula (A-1) with a specified ratio and another constituent unit derived from a specified (meth)acrylate ester monomer, the non-fluorinated polymer () containing a constituent unit derived from at least one monomer of methyl methacrylate and ethyl methacrylate with a specified ratio and a another constituent unit derived from another specified (meth)acrylate ester monomer:

##STR00001## wherein R.sup.1 represents a hydrogen atom or a methyl group, and R.sup.2 represents a monovalent hydrocarbon group having 12 to 30 carbon atoms, optionally having a substituent.

In one aspect, a composition for treating fibers comprises an acidic aqueous or aqueous-based continuous phase and a liquid repellent phase comprising a dendrimer component and/or non-dendrimer alkyl urethane. The treatment composition, for example, can have pH of 2.5 to 6.5. In some embodiments, carboxylic acid is employed in the treatment composition for providing the acidic character of the aqueous or aqueous-based continuous phase. Moreover, the treatment composition can further comprise at least one of an acid stain resist component and soil release component. In some embodiments, fibers treated with compositions described herein exhibit ionic character.

The present invention relates to a fabric treatment composition capable of enhancing cleaning properties of a soil during cleaning through treatment of a fabric to be treated and a method for treating a fabric with the fabric treatment composition. The fabric treatment composition is a fabric treatment composition containing a hydroxyalkyl cellulose (A) in which a hydroxyalkyl cellulose is bound to at least one selected from a cationic group and a hydrophobic group including a hydrocarbon group having 4 or more carbon atoms, the content of a surfactant (B) being 3.5 parts by mass or less relative to 1 part by mass of the hydroxyalkyl cellulose (A).

A fabric treatment composition is provided that includes at least one zeta potential modifier, a fluoropolymer and a hydrophobic agent with a melting point or glass transition temperature below 100 C., for imparting fabric protection benefits to a fabric, such as improved stain and soil resistance, oil repellency, water repellency, softness, wrinkle and damage resistance, and better hand feel. Fabric treatment compositions can be used as a pretreatment prior to washing, through soaking, or added to the treatment liquor, that is either the wash or rinse cycle of an automatic washing machine, to first provide and then maintain and refresh the fabric protection benefits imparted to the fabric, with the proviso that an intermediate rinsing step essentially devoid of added surfactant-is used after the washing cycle and prior to the fabric treatment step. Following use of a first treatment composition, protective benefits are maintained and refreshed by means of a second treatment operation employing a second treatment composition. The second treatment composition may have lower active levels of the protective agents to provide for economical and periodic maintenance of the imparted fabric protection benefits.

A method of treatment of one or more articles may comprise locating a stain on an article based on a tag on the article; placing the stain on a nose of a spotting board; positioning a steam gun at least two or more inches away from the stain; simultaneously activating a steam supply and a vacuum supply of the spotting board; moving the steam gun in a defined motion relative to the stain for at least 30 seconds; simultaneously activating the vacuum supply and an air supply of the spotting board; moving the steam gun in the defined motion relative to the stain until the article is at least partially dry; and inspecting the stain.

A method for quantitatively and indirectly measuring non-fluorine anti-soil chemistry in carpet applications, is based on a known amount of FI trace to be added along with anti-soil chemistry in formulation prior to application to a carpet surface. The anti-soil chemistry with the trace amount of FI is then applied to the carpet through a topical foam or spray applicator during a precoating process. After completion of the precoat process, a carpet sample is collected, carpet face fiber is shaved, and FI is extracted using water. The extracted water solution is used to measure the fluorescence intensity (in counts per second or CPS) using a Fluorimeter.
