Embodiment 1

[0049] Example 1: Application of sodium cyclamate in textiles

[0050] It is known that the breaking strength of the undesized pure cotton plain weave fabric before treatment is 508.4N, and the Hunter whiteness is 53.8.

[0051] (1) Preparation of bleaching working solution: with sodium N-cyclohexyl sulfamate 20g / L, stabilizer 4g / L, chelating agent 3g / L, penetrant 2g / L, H 2 O 2 The bleaching solution was prepared in an amount of 65 g / L, and then the pH was adjusted to 12 with NaOH.

[0052] (2) Padding: the fabric is placed in the above-mentioned bleaching working solution for padding treatment, two dips and two rolls, and the over-rolling rate of the fabric is controlled to be 100%.

[0053] (3) Rolling and stacking: The padding fabrics are stacked at 20°C for 24 hours.

[0054] (4) Washing: washing and drying the bleached fabric.

[0055] The fabric treated by this method has a strength retention rate of 95.98% and a Hunter whiteness of 81.83 according to the national s...

Embodiment 2

[0056] Embodiment 2: a kind of bleaching liquid

[0057] A bleaching solution comprising 5g / L of sodium N-cyclohexyl sulfamate, 4g / L of stabilizer, 2g / L of chelating agent, 2g / L of penetrant and H 2 O 2 60 g / L, pH was adjusted to 12 with NaOH.

[0058] The cotton fabric is bleached with the bleaching solution of the present embodiment, comprising the following steps:

[0059] (1) padding: the fabric is placed in the above-mentioned bleaching solution for padding, two dips and two rollings, and the over-rolling ratio of the control fabric is 100%;

[0060] (2) Rolling and stacking: the cotton fabrics after padding are rolled and stacked, and stacked at 20°C for 24 hours;

[0061] (3) Washing: washing and drying the fabric after cold heap bleaching.

[0062] The breaking strength of the fabric before treatment is known to be 508.4N and the Hunter whiteness is 53.8. The fabric treated by this method has a strength retention rate of 90.14% and a Hunter whiteness of 81.54 mea...

Embodiment 3

[0063] Embodiment 3: a kind of bleaching liquid

[0064] A bleaching solution comprising 10g / L of sodium N-cyclohexyl sulfamate, 4g / L of stabilizer, 2g / L of chelating agent, 2g / L of penetrant and H 2 O 2 60 g / L, pH was adjusted to 12 with NaOH.

[0065] The cotton fabric is bleached with the bleaching solution of the present embodiment, comprising the following steps:

[0066] (1) padding: the fabric is placed in the above-mentioned bleaching solution for padding, two dips and two rollings, and the over-rolling ratio of the control fabric is 100%;

[0067] (2) Rolling and stacking: the cotton fabrics after padding are rolled and stacked, and stacked at 20°C for 24 hours;

[0068] (3) Washing: washing and drying the fabric after cold heap bleaching.

[0069] The breaking strength of the fabric before treatment is known to be 508.4N and the Hunter whiteness is 53.8. The fabric treated by this method, according to the national standards GB / T 3923.1-2013 and GB / T 17644-1998,...

Abstract

The invention discloses a low-strength-loss cold heap bleaching method of cotton fabrics, which belongs to the field of textile pretreatment and post-finishing. In the invention, by introducing sodium N-cyclohexyl sulfamate as a strong protective agent in different processing and finishing of textiles, not only the cotton fabric is bleached by means of cold heap, the effect of bleaching the cotton fabric is achieved; the method of rolling and baking is also adopted. Anti-felting finishing and anti-pilling finishing are carried out, which endow the wool fabric with anti-felting performance and anti-pilling performance respectively. The invention provides a strong protective agent with high versatility and excellent effect, which can be used in the processing and finishing of cotton, linen, wool and chemical fiber products, and the strong damage of the fabric obtained by the treatment of the invention can be kept below 5%, Has a high strength retention rate.

Description

technical field [0001] The invention belongs to the field of textile pretreatment and post-finishing, and particularly relates to a method for low-strength-loss cold heap bleaching of cotton fabrics. Background technique [0002] With the continuous development and progress of science and technology and economy, people's demand for different functional textiles is increasing, traditional finishing technology needs to adapt to new development, and textile functional finishing technology needs to be innovated urgently. According to the different consumption needs in daily life, different textiles will undergo a variety of finishing processes, such as bleaching, anti-felt finishing, anti-pilling finishing, and non-iron finishing. These finishing processes will cause greater damage to the textiles. In actual production, yarns and fabrics with greater strength are usually used to reserve the damaged parts of the textiles, so that the finished fabrics can meet the wearing standard...
