Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a non-strength and non-ironing finishing method for pure cotton fabrics, which has the characteristics of easy operation and control, and can solve the problem that the strength of pure cotton high-count and high-density fabrics decreases during non-ironing finishing , so that the dp level of the fabric reaches 3.5 during non-ironing finishing, and the strength is basically not damaged, which greatly improves the wearability of cotton fabrics

Embodiment 1

[0073] The non-strength and non-ironing finishing method of pure cotton fabric is applied to the non-ironing finishing process of cotton fabric during dyeing and finishing, and the steps include:

[0074] A. The preparation of the non-ironing finishing working solution, the formula of the working solution is calculated according to the ratio of parts by weight:

[0075] Etherification modified resin EMT-16, 60 parts;

[0076] Modified polyether polyurethane PU, 100 parts;

[0077] Modified amino silicon, 30 parts;

[0078] The solid content in the emulsion is 20% PVC emulsion, 40 parts;

[0079] Water, 770 parts;

[0080] B, padding, utilize acetic acid to adjust the pH value of the non-ironing finishing working solution gained in step A to be 4-5, and the fabric is dipped and rolled, and the liquid-carrying rate is 70%; the product obtained enters the post-treatment process;

[0081] C, drying, drying the fabric obtained in step B at a temperature of 95° C. for 2 minutes;...

Abstract

The invention discloses a non-strength-reducing easy-care finishing method for pure cotton fabrics, which is applied to an easy-care finishing process in the process of dyeing and finishing cotton fabrics. The method comprises the following steps of: A, preparing an easy-care finishing working solution, wherein the easy-care finishing working solution is prepared from the following components in parts by weight: 60 parts of etherified modified resins, 100 parts of modified polyether polyurethane, 30 parts of modified amino silicone, and 40 parts of PVC emulsion 20; B, padding: adjusting the pH value of the easy-care finishing working solution obtained in the step A to be 4-5, and dipping and rolling a fabric, so that the liquid carrying ratio of the fabric is 70%; and implementing a post-treatment process on the obtained product; C, drying: drying the fabric obtained in the step B for 2 min at a temperature of 95 DEG C; D, preshrinking treatment: carrying out conventional preshrinking treatment on the fabric obtained in the step C; and E, baking: baking the obtained product for 1 min at a temperature of 160 DEG C. The wear resistance and seam slippage of the obtained product are significantly improved, each index is superior to that of the existing process, and the product strength is almost not damaged.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing technology, in particular to a high-grade non-ironing finishing suitable for pure cotton woven fabrics. Background technique [0002] Cotton fabric has the characteristics of natural hand feeling, moisture absorption, breathability, antistatic, no stimulation to the human body, comfortable wearing, etc., and is degradable. It has always been an environmentally friendly fabric highly praised by consumers. However, cotton fabrics have the disadvantages of poor wrinkle resistance, easy deformation, and large shrinkage. Therefore, it is necessary to perform non-ironing finishing on cotton fabrics. Non-ironing finishing improves the wrinkle recovery of pure cotton fabrics and the flatness of pure cotton fabrics after washing, but at the same time, it has a great loss of physical properties of cotton fabrics. For thin pure cotton fabrics, due to its low absolute value of strength Therefore,...
