Problems solved by technology

The existing waterproof microfiber leather and antibacterial microfiber leather have been widely popular in the market, but the technology of waterproof and antibacterial microfiber leather for outdoor use is not stable
[0003] Initially, the post-finishing technology of co-bathing with C8 waterproofing agent and antibacterial agent can meet the requirements, but C8 contains harmful substances such as PFOA and PFOS, which does not conform to the concept of environmental protection of consumers, so C8 products are gradually replaced by C6 which does not contain PFOA and PFOS. product replacement
[0004] However, it has been proved that the finishing technology after co-bathing with C6 waterproofing agent and antibacterial agent is not stable, and there are large differences between the waterproof and antibacterial effects of different batches of products

Embodiment 1

[0027] (1) Padding finishing agent: impregnate the microfiber suede leather in the finishing agent, 4 dips and 4 pads, with a liquid retention rate of 55%, drying at 130°C for 10 minutes, then cooling and winding.

[0028] The finishing agent is composed of the following components in parts by weight:

[0029]

[0030] Adjust the pH to 4.5 with acetic acid

[0031] (2) Printing antibacterial agent: apply oily antibacterial agent ATE 9280 on the front and back of the microfiber leather,

[0032] The amount of roller coating is 2g / m 2 , and then dried at 120°C, and finally cooled and rolled.

[0033] The microfiber leather obtained by this process can achieve the following effects:

[0034] Water absorption rate 5.2%, water penetration 0.02g, water vapor penetration 10mg / cm 2 h (test standard ISO 20345); meanwhile, anti-Klebsiella pneumoniae is 95%, (test standard ATCC 4352), and anti-Staphylococcus aureus is 93% (test standard ATCC 6538).

Embodiment 2

[0036] (1) Padding finishing agent: impregnate the microfiber suede leather in the finishing agent, 4 dips and 4 pads, with a liquid retention rate of 60%, drying at 135°C for 12 minutes, then cooling and winding.

[0037] The finishing agent is composed of the following components in parts by weight:

[0038]

[0039]

[0040] Adjust the pH to 5 with acetic acid

[0041] (2) Printing antibacterial agent: apply oil-based antibacterial agent ATE 9280 on the front and back of the microfiber leather, and the amount of roller coating is 7g / m 2 , and then dried at 120°C, and finally cooled and rolled.

[0042] The microfiber leather obtained by this process can achieve the following effects:

[0043] Water absorption rate 9.9%, water penetration 0.15g, water vapor penetration 13mg / cm 2 h (test standard ISO 20345); meanwhile, anti-Klebsiella pneumoniae is 92% (test standard ATCC 4352), and anti-Staphylococcus aureus is 94% (test standard ATCC 6538).

Embodiment 3

[0045] (1) Padding finishing agent: impregnate the microfiber suede leather in the finishing agent, 4 dips and 4 pads, with a liquid retention rate of 60%, drying at 135°C for 10 minutes, then cooling and winding.

[0046] The finishing agent is composed of the following components in parts by weight:

[0047]

[0048] Adjust the pH to 5 with acetic acid

[0049] (2) Printing antibacterial agent: apply oily antibacterial agent SKANEòM-8 on the front and back of the microfiber leather, and the amount of roller coating is 10g / m 2 , and then dried at 120°C, and finally cooled and rolled.

[0050] The microfiber leather obtained by this process can achieve the following effects:

[0051] Water absorption rate 4.3%, water penetration 0.02g, water vapor penetration 11mg / cm 2 h (test standard ISO 20345); meanwhile, anti-Klebsiella pneumoniae is 91% (test standard ATCC 4352), and anti-Staphylococcus aureus is 92% (test standard ATCC 6538).

Abstract

The invention discloses outdoor waterproof antibacterial superfine fiber synthetic leather and a finishing method thereof, wherein a preparation method of the synthetic leather comprises the following steps: (1) immersing superfine fiber synthetic leather in a treatment liquid, and padding, wherein the liquid carrying rate of the superfine fiber synthetic leather is 50%-70%, and the treatment liquid comprises the following components in parts by weight: 7-10 parts of a C6 waterproof finishing agent, 3-7 parts of a water-based antibacterial agent, 1-3 parts of a water-based crosslinking agent, and 100 parts of deionized water, wherein the pH is 4-6; (2) drying the product of the step (1), cooling and coiling; and (3) roll-coating the front face and the reverse face of the superfine fiber synthetic leather of the step (2) with an oily antibacterial agent, drying, cooling and coiling, and thus obtaining the externally-applied waterproof antibacterial superfine fiber synthetic leather. The superfine fiber synthetic leather produced by the method has stable waterproof antibacterial quality, and overcomes the defect that the waterproof property and the antibacterial property cannot reach the standards at the same time; and the product has good breathability and moisture permeability and strong scratch resistance, and is suitable for outdoor protective shoes and protective gloves.

Description

technical field [0001] The invention relates to a finishing method for suede superfine fiber synthetic leather. Background technique [0002] In recent years, suede microfiber synthetic leather has become more and more popular among consumers and has become the mainstream product of microfiber synthetic leather. At the same time, functional microfiber leather has gradually entered the stage and occupied a place in the market. As people pursue outdoor activities, the requirements for outdoor protective equipment are getting higher and higher, especially protective shoes and protective gloves, which are required to have functions such as waterproof, breathable, antibacterial, wear-resistant, and scratch-resistant. Existing waterproof microfiber leather and antibacterial microfiber leather have been widely popular in the market, but the waterproof and antibacterial microfiber leather technology for outdoor use is not stable. [0003] Initially, the post-finishing technology of...
