Downproof finishing agent and finishing process thereof on downproof fabric

Abstract

The invention discloses a downproof finishing agent and a finishing process thereof on a downproof fabric; the downproof finishing agent is a mixed aqueous solution of an acrylate-ammonia ester-organosilicone copolymerized modified polymer, an acrylate-ammonia ester-organosilicone copolymerized modified polymer, a ternary copolymerized silicone oil and a surfactant, wherein the content of the acrylate-ammonia ester-organosilicone copolymerized modified polymer is 30-80 g / L, the content of the ternary copolymerized silicone oil is 10-50 g / L, and the content of the surfactant is 1-5 g / L. The finishing process comprises the steps: firstly, preparing the downproof finishing agent, and then padding, drying, preshrinking, calendering and re-preshrinking, to obtain a finished fabric. After the fabric is padded in the finishing agent, fiber cracks are plugged through bonding, the fastness is increased, and the fabric handfeeling is improved; then through compounding with the ternary copolymerized silicone oil softener and the surfactant and the preshrinking, calendering and re-preshrinking processes, the fabric is guaranteed to have good downproof effect and also have a soft, matte and active fabric style.

Description

technical field [0001] The invention belongs to the technical field of textile post-finishing aids, and in particular relates to a down-drilling-proof finishing agent and its finishing process on feather-proof fabrics. Background technique [0002] Textile fabrics used for processing down products (down clothing, down bedding) must have excellent anti-drilling performance, which is sufficient to prevent down or feathers used as filling layers from drilling out of the fabric during use. To make the fabric have excellent anti-drilling performance, the common method is to use high-count and high-density processing methods. This method brings fabrics with soft texture, smooth surface, uniform cloth surface, clean lines, anti-drilling and breathable. The performance is good, but this kind of high-count and high-density fabric has strict requirements on processing technology, is difficult to weave, and has high cost, so it has not been fully popularized yet. The second is to use ...

Problems solved by technology

To make the fabric have excellent anti-drilling performance, the common method is to use high-count and high-density processing methods. This method brings fabrics with soft texture, smooth surface, uniform cloth surface, clean lines, anti-drilling and breathable. Good performance, but this kind of high-count and high-density fabric has strict requirements on processing technology, difficult weaving, and high cost. It has not been fully popularized yet.

The second is to use anti-drilling wool padding or coating finishing in the dyeing and finishing process. Coating finishing is the most common finishing method at present. The fabric obtained has a loud friction sound, and is hard and smooth. At present, it is the most extensive processing method; while the method of padding the anti-drilling finishing agent can avoid the defects caused by the coating, but the preparation of the anti-drilling finishing agent is very particular, if underestimated, it will bring anti-drilling The effect of drill fleece is not good or the effect of coating is the same

Patent CN 103147205A uses padding anti-feather finishing agent to carry out anti-drilling and soft finishing. The anti-feather finishing agent used is a special aliphatic polymer compound emulsion containing organic silicon and a hydrophilic softener. The resulting fabric has a good hand feel, but due to The anti-feather finishing agent has a single component, which only plays a soft role, and has little anti-drilling effect

Patent CN103535950A discloses anti-drilling finishing containing a compound of starch composite catalyst and acrylic acid acrylamide compound, but the film-forming material of acrylic acid acrylic acid acrylamide has a hard hand and serious yellowing, which has a great influence on the feel and appearance of the fabric
