Problems solved by technology

[0003] At present, there is a "minus-plus" combined method for anti-pilling finishing of woolen sweaters, but many chemical agents are used in this method, such as: biological enzymes, reducing agents, penetrating agents, oxidizing agents, resins, catalysts, softeners, etc. And it needs to be divided into 3 steps to complete, the process is complex, the processing time is long, the fiber damage is large, and the discoloration is serious

Embodiment 1

[0039] Embodiment 1: pile fabric anti-pilling finishing liquid, it comprises the component of following parts by weight: reducing agent 1.5% (o.w.f), penetrating agent 1% (o.w.f), amino silicone oil 3% (o.w.f) and protease 0.1% (o.w.f ). In this example, the reducing agent is TCEP; the penetrating agent is JFC; the amino silicone oil is amino silicone oil SL-2006; the protease is 16L enzyme.

[0040] Among them, the 16L enzyme adopts Novozymes’ 16L enzyme, also known as subtilisin, its main component is serine endopeptidase, and its appearance color is a translucent amber liquid. The optimum enzyme activity condition is: pH=7-10. Under the condition of alkaline pH=8.5-9, at 50°C, the enzyme activity is the highest, which can reach about 500,000 U / g.

[0041] TCEP is soluble in water, its chemical name is tris(2-carboxyethyl)phosphine, and its chemical formula is C 9 h 16 CLOs 6 P; is a very effective thiol reducing agent. It is a colorless transparent liquid with good st...

Embodiment 2

[0044] Embodiment 2: a method for anti-pilling finishing of pile fabrics, which comprises the following steps: (1) soaking and pretreatment of pile fabrics; (2) preparing an anti-pilling finishing liquid for pile fabrics; (3) anti-pilling finishing of pile fabrics; (4) Dehydration and drying after finishing. in:

[0045](1) Soaking pretreatment of fluffy fabric: Soak the fluffy fabric in warm water at 45°C for 10 minutes, with a bath ratio of 1:20;

[0046] (2) Prepare anti-pilling finishing solution for fluffy fabric: after soaking, keep the temperature constant, add reducing agent under running conditions, then quickly adjust the pH value to 7.5, then add penetrant, amino silicone oil and protease in sequence, and you are done. Prepared as an anti-pilling finishing solution; the addition of the reducing agent is 1.5% of the weight of the pile fabric, the addition of the penetrating agent is 1% of the weight of the pile fabric, and the addition of the amino silicone oil is 1...

Embodiment 3

[0050] Embodiment 3: pile fabric anti-pilling finishing liquid, it comprises following components: reducing agent 2.0% (o.w.f), penetrating agent 1.5% (o.w.f), amino silicone oil 4% (o.w.f) and protease 0.15% (o.w.f). In this example, the reducing agent is TCEP; the penetrating agent is JFC; the amino silicone oil is amino silicone oil SL-2006; the protease is 16L enzyme.

[0051] Among them, the 16L enzyme adopts Novozymes’ 16L enzyme, also known as subtilisin, its main component is serine endopeptidase, and its appearance color is a translucent amber liquid. The optimum enzyme activity condition is: pH=7-10. Under the condition of alkaline pH=8.5-9, at 50°C, the enzyme activity is the highest, which can reach about 500,000 U / g.

[0052] TCEP is soluble in water, its chemical name is tris(2-carboxyethyl)phosphine, and its chemical formula is C 9 h 16 CLOs 6 P; is a very effective thiol reducing agent. It is a colorless transparent liquid with good stability and solubilit...

Abstract

The invention discloses an anti-pilling finishing method and an anti-pilling finishing liquid for a fluffy fabric. The anti-pilling finishing method for the fluffy fabric comprises the following steps of (1) conducting soaking pretreatment of the fluffy fabric; (2) preparing the anti-pilling finishing liquid for the fluffy fabric; (3) conducting anti-pilling finishing of the fluffy fabric; and (4) dewatering and drying after finishing. The anti-pilling finishing liquid for the fluffy fabric comprises the following components of 1.5-2.0% (o.w.f) of a reducing agent, 1-1.5% (o.w.f) of a penetrating agent, 3-4% (o.w.f) of amino silicon oil and 0.1-0.15% (o.w.f) of protease. The fluffy fabric finished by the method is measured by a box-type pilling instrument, the anti-pilling grade can reach 4-5 grade after 2 hours of rolling friction, and the anti-pilling grade can reach 4 grade after 5 hours of rolling friction. The technology is simple, the finishing time is shortened to only 20 min, damage to fiber strength is small, discoloration is avoided, the hand feeling is good, and wool falling does not exist in a box after 2-5 hours of rolling friction.

Description

Technical field: [0001] The invention relates to the technical field of textile processing, in particular to an anti-pilling finishing method for pile fabrics and an anti-pilling finishing solution for pile fabrics. Background technique: [0002] Wool and cashmere fiber knitted fabrics have low yarn twist and low tissue density. Therefore, in the process of processing, wearing and washing, woolen sweaters will form fluff when they are rubbed; as the exposed length of fluff continues to increase, the scale structure of fluff fibers and better fiber elasticity will make fluff intertwined with each other, gradually forming fiber balls, That is, pilling occurs. Pilling will affect the appearance and comfort of clothes, thereby affecting the quality of clothes. The anti-pilling of fleece is an old subject and a big problem. [0003] At present, there is a "minus-plus" combined method for anti-pilling finishing of woolen sweaters, but many chemical agents are used in this metho...
