Problems solved by technology

Although the softening agent is mentioned in the finishing agent A, finishing agent B, and finishing slurry C, the structure of the softening agent is not specified. First, the three-step finishing method will increase energy consumption for printing and dyeing enterprises. The corresponding production cost will also be greatly increased; secondly, after three times of high-temperature baking will cause strong damage to the fabric, pure cotton satin fabric is not suitable for this process; at the same time, the finishing agent B in this method contains OEKO-TEX Standard 100 standard Banned organotin catalysts, do not meet current environmental protection requirements
[0006] At present, there is no imitation silk finishing agent and disclosed technology for pure cotton satin fabric on the market.

Abstract

The invention discloses a purified cotton satin weave fabric silk-like finishing agent and a preparation method. The finishing agent is composed of amino polyether-modified polysiloxane, quaternized polyether blocked polysiloxane, an easy-care resin finishing agent and nonionic polyurethane emulsion; after the finishing agent is applied to afterfinish of purified cotton satin weave fabric, the fabric has the silk-like hand feeling and gloss, the fabric can have the appearance flatness of more than 3 level, and the fluffing and pilling of more than 3 levels.

Description

technical field [0001] The invention relates to the finishing technology of textile fabrics, in particular to a silk-like finishing agent for pure cotton satin fabrics and a preparation method thereof. The finishing agent is mainly composed of amino polyether modified polyorganosiloxane, quaternized polyether block polyorganosiloxane, non-ironing resin finishing agent, soft non-ionic polyurethane emulsion, and is used for pure cotton satin fabric After finishing, it has the feel and luster of silk fabric, the appearance flatness (non-ironing DP value) of the fabric can reach above grade 3, and the pilling can reach above grade 3. Background technique [0002] Silk fabrics are loved by people because of their gorgeous and rich appearance, as well as their comfort and skin-friendly effects. They are mostly used in clothing and bedding that are in direct contact with the skin. However, silk fabrics also have disadvantages such as easy wrinkling, easy snagging, water stains aft...
