Make the lignin on fabric, starch size, cotton wax and cotton seed hulls degraded using compound enzyme system and emulsify, lignin
Enzyme is used cooperatively with cellulase, assists in removing the lignin of cotton seed hulls and fiber finer cell wall, and compound pectinase enters nascent
Cell wall layer makes pectic substance degrade so that the passage for leading to fiber blister cavities is opened, the short fibre on cellulase removal yarn beam surface, effectively
The problem that cotton seed hulls is difficult to remove in cellulase treatment is solved, caustic soda, chemical agent, steam, electric power, water had both been reduced
And the COD contents of sewage discharge, causing that production process becomes simple controllable again, the processing to multifilament composite material becomes letter
It is single easy, improve the quality and quality of product.
Whole art production process nonhazardous material is produced, and technical process can be operated continuously, and process is simple, flow are short.Through
Fabric cotton seed hulls removal after this PROCESS FOR TREATMENT is preferable, and body flexibility is good, will not damage fiber, and fabric does not drop by force, weight-loss ratio
It is low.Technological process is short, energy-saving, can be reduced with water at least 3/4 than traditional caustic soda hydrogen peroxide process, reduce energy consumption (steam,
Electricity) more than 60%, the COD in waste discharge is reduced, its value is only the 1/8~1/6 of traditional handicraft, and pH value of waste water can reach directly
Emission request (pH=7~8).And acid neutralization, deoxygenase deoxygenation are not needed after ferment treatment, it is easily biological because enzyme is protein
Decompose, really embody energy-saving and emission-reduction.
Described pads net cotton enzymatic process, can effectively remove impurity, slurry, wax, pigment in bafta etc., makes fabric
Any surface finish, improved from degree, it is soft smooth, its hydrophily, water suction diffusance etc. are significantly improved, and can improve in dyeing
Color rate and level-dyeing property, simplify production technology, reduce work hours, reduce production cost, greatly reduce sewage discharge, can substitute caustic soda,
Various auxiliary agents such as bleeding agent, scouring agent, stabilizer, soft treatment reduces softening agent consumption at least 3/4.In addition, fatty alcohol polyoxy
Glycol ether 5-sodium sulfo isophthalate ester bathes softening agent as fabric, and with alkali resistance high, (≤25g/L soda ash is water-soluble
Liquid), low bubble (0.25mL compounding agent solutions 50mL tool plug graduated cylinder in shake its moment of 1min steep 0.8cm (foaming characteristic) high, after 5min
Steep 0.3cm high (defoaming)) performance, fabric can be helped to be not likely to produce folding line in dyeing, and fabric have concurrently it is soft and
Anlistatig effect, and preparation cost is low.

Acid -5- sulfonic acid sodium esters；
The AEO is 2.4 with the mol ratio of 5-sodium sulfo isophthalate:1；
The AEO molecular formula formula is：
C16H33O(CH2CH2O)6H
Using embodiment 1-5 processing steps, to being compared as follows with traditional alkali process method after cotton and polyester cotton treatment
Shown in table：
From above table comparative result, it is seen then that technical scheme, by the improvement of process conditions and formula, completely
Traditional alkali process method can be substituted, the lignin on fabric, starch size, cotton wax and cotton seed hulls is degraded using compound enzyme system
And emulsification, lignoenzyme uses cooperatively with cellulase, assists in removing the lignin of cotton seed hulls and fiber finer cell wall, composite fruit
Glue enzyme makes pectic substance degrade into primary cell wall layer so that the passage for leading to fiber blister cavities is opened, cellulase removal yarn beam table
The short fibre in face, efficiently solves the problem that cotton seed hulls is difficult to remove in cellulase treatment, both reduced caustic soda, chemical agent,
The COD contents of steam, electric power, water and sewage discharge, cause that production process becomes simple controllable, to multifilament composite surface again
The processing of material becomes simple and easy to apply, improves the quality and quality of product.
