SILICONE POLYETHER POLYMER TREATMENTS FOR FIBROUS SUBSTRATES
Described is a fibrous substrate treatment composition having a) 20-99.5% by weight of a silicone polyether polymer and b) 0.5-4% by weight of a cationic surfactant or a mixture of cationic and nonionic surfactant; wherein the silicone polyether polymer has 6-100% by weight of formula (I) or (II) and 0-94% by weight of repeat units from ethylenically unsaturated comonomers;
##STR00001##
wherein a and b are integers of 1 to 40 where a+b is an integer of at least 2; c and d are integers of 0 to 20; e is an integer of 1 to 40; X is a linear or branched C.sub.1-C.sub.4 alkylene group; R.sup.1 is a C.sub.1-C.sub.4 alkyl group; and R.sup.2 is —C(R.sup.1)═CH.sub.2 or polymer backbone unit —[C(R.sup.1)—CH.sub.2]— bonded at C(R.sup.1). Treatments exhibit improved balance of water repellency and oily stain release performance.

Method for making antimicrobial article
A method of making an antimicrobial textile comprising TiO.sub.2 nanoparticles is described. The TiO.sub.2 nanoparticles are immobilized by first treating a textile with a base, and then contacting with TiO.sub.2 nanoparticles in a solution of an alcohol and acid. The textile may be subsequently irradiated with UV light prior to use. The antimicrobial textile shows high effectiveness against the growth and proliferation of microorganisms transmitted within indoor environments.

POLYESTER COTTON-LIKE YARN-DYED FABRIC, AND MANUFACTURING METHOD AND APPLICATION THEREOF
Disclosed are a polyester cotton-like yarn-dyed fabric, and a manufacturing method and application thereof. The polyester cotton-like yarn-dyed fabric is interwoven by warp and weft, the warp adopts dyed polyester as a covering layer and low-temperature spandex as a core-spun yarn of a core yarn, a weight ratio of the polyester to the low-temperature spandex is 4-49:1, and the polyester is subjected to alkali deweighting treatment to form an eroded surface. The polyester cotton-like yarn-dyed fabric has good cotton feeling, high elasticity, high color fastness and low ironing shrinkage rate, and is suitable for making high-quality clothing, especially shirts. The manufacturing method of the yarn-dyed fabric is energy-saving and emission-reducing, and can manufacture a novel polyester yarn-dyed fabric with low ironing shrinkage rate, high color fastness and cotton-like hand feeling. Use of the yarn-dyed fabric for making clothing such as shirts increases the selectivity and functionality.
