N-methylol acrylamide) either individually or in combination is chemically modified jute is found to improve or alter the important textile related properties like moisture regain, tensile properties, fabric stiffness, crease recovery angle, shrinkage parameters, and thermal behavior.
This leads to reduction in warp-way tenacity.
The polymerization and condensation reaction of N-methylolacrylamide within cotton fabrics in which K2S2O8, (NH4) 2S 2O8, or H2O2 can be used as initiator and NH4 Cl or (NH4 )2HPO4 used as the acid condensation catalyst.
Crease recovery and abrasion resistance (flat) of the treated fabric increased with higher value of resin content; tear strength.
The effect of the addition of acid catalysts such as NH4Cl on the extent of the crease resistance is considerable, although some marked improvement was obtained in neutral catalysts such as K2S2O8 alone.

Treatment usefulness
The addition of co-monomers such as acrylamide and hexamethylene diamine HCl-salt as well as softeners to the treating bath may be effective in improving the strength losses induced by this treatment.
Aftertreatment of the N-methylolacrylamide-treated fabric with hexamethylenediamine or thereafter with formalin may be also effective, since somewhat continuous distribution of the different kinds of network-structures within the fiber could be obtained by this procedure.

Abstract
Several variations of polymerization-crosslinking of N-methylolacrylamide (NMA) in cotton were explored to clarify factors critical to achievement of resilience with superior retentions of strength and abrasion resistance in fabric.
Per sulfate catalysis simultaneously initiated both polymerization and crosslinking reactions of NMA in cotton fabric; the results from dry-cure reactions fell in the conventional range of textile performance properties achieved by treatment of cotton fabric with agents such as dimethyloldihydroxyethyleneurea.
Wet-cure reactions carried out in scaled bags at or above 100°C resulted in low resilience, high retentions of strength-abrasion resistance, and large increases in stiffness, the last attributed to fiber bonding in yarns. Wet-cure reactions conducted at or below 80°C caused little stiffness, and only in these cases was a subsequent catalyzed dry-cure reaction effective in raising resilience with good retentions of strength and abrasion resistance.
Inclusion of alkali metal phosphates in the persulfate-initiated reaction of NMA with cotton in a pad-dry-cure caused retentions of abrasion resistance to be very substantially improved and retentions in breaking and tearing strengths to be significantly improved at durable-press appearance ratings of 4.5.
These results are attributed to relatively sequential but rapid polymerization and crosslinking reactions, to reduction in formation of oxymethylene crosslinks, and possibly to reduced molccular degradation of the cellulose.

Product Name：N-Methylol Acrylamide (NMA)
Product feature：
NMA is a special monomer with two functional groups, they are ethenyl and methylol.
Through emulsion polymerization or solution polymerization, thermoplastic polymer may be obtained by comining NMA with many kinds of ethenyl monomer.
Because there are functional groups of methylol in the branch chain, this thermoplastic polymer can self cross-link into cross-linked polymer under certain condition.

N-Methylolacrylamide Usage

1. A widely used cross-linking monomer for fiber modification, resin processing, adhesives and paper, leather, metal surface treatment agents, and soil improvers.

2. As an organic synthesis monomer, it can be used to prepare a variety of copolymers.

Polymerization and Condensation Reaction of N-Methylol Acrylamide within Cotton Fabric [1960]
Kamogawa, H.; Murase, R.; Sekiya, T.;
Problems on the polymerization and condensation reaction of N-methylolacrylamide within cotton fabrics in which K₂S₂O₈, (NH₄) ₂S ₂O₈, or H₂O₂ was used as initiator and NH₄ Cl or (NH₄)₂HPO₄ used as the acid condensation catalyst were investigated primarily from the standpoint of the crease resistance of the treated fahric.
The results obtained are as follows.
The pre-drying process can be neglected, as almost the same result could be obtained even in the case of direct curing procedure, in which care should be taken not to over- cure.
Crease recovery and abrasion resistance (flat) of the treated fabric increased with higher value of resin content ; tear strength, on the contrary, decreased presumably with some intrinsic cause.
The effect of the addition of acid catalysts such as NH₄Cl on the extent of the crease resistance was considerable, although some marked improvement was obtained in neutral catalysts such as K₂S₂O₈ alone.
The addition of comonomers such as acrylamide and hexamethylene diamine HCl-salt as well as softeners to the treating bath was effective in improving the strength losses induced by this treatment.
Aftertreatment of the N-methylolacrylamide-treated fabric with hexamethylenediamine or thereafter with formalin was also effective, since some what continuous distribution of the different kinds of network-structures within the fiber could be obtained by this procedure.
Durability of the treated fabric for boiling-alkali launderings was excellent.

AEROTEX® NMA-LF Monomer
AEROTEX NMA-LF is specifically designed to provide effective selfcrosslinking performance together with a significant reduction in both the formaldehyde present in the resulting emulsion polymer and the formaldehyde released to the environment upon curing.
AEROTEX NMALF combines the cost effectiveness of AEROTEX NMA with a dramatic reduction in total formaldehyde.
The active self-crosslinking species of AEROTEX NMA-LF is N-methylolacrylamide (NMA).
NMA contains both a vinyl group and an N-methylol group.
The vinyl group is reactive and enables the NMA to be readily incorporated into a variety of polymer backbones.
Once incorporated into the polymer, the methylol group can be triggered to undergo crosslinking with itself, other functional groups in the polymer (such as hydroxyls or amines), or with cellulosic substrates.
The bifunctional feature of AEROTEX NMA-LF ultimately results in latex binders which provide important performance properties to the final product, such as wet strength, tear strength, and solvent resistance.

N-Methylolacrylamide Usage

1. A widely used cross-linking monomer for fiber modification, resin processing, adhesives and paper, leather, metal surface treatment agents, and soil improvers.

2. As an organic synthesis monomer, it can be used to prepare a variety of copolymers.

Reactivity Uses FLOCRYL NMA is supplied as a 48% solution in water.
Its reactivity is due to the presence in the molecule of both an unsaturated vinyl group and a hydroxymethyl group which can be reacted separately and/or independently simply by varying the reaction conditions.
Reaction of the vinyl group FLOCRYL NMA can be used in the preparation of a wide range of polymers and copolymers.
The main is free radical polymerisation with other vinyl monomers such as acrylonitrile, acrylamide, acrylic and methacrylic esters, vinyl chloride, and styrene which leaves the hydroxymethyl group available.
Additionally, the double bond in FLOCRYL NMA can be reacted with both halogens and alcohols under alkaline conditions and with thiol in the presence of alcoholate.
Reaction of the hydroxymethyl group The hydroxymethyl group has a tendency to undergo condensation or substitution reactions.
FLOCRYL NMA containing polymers can be crosslinked either with themselves or with other reactive monomers, by heating and/or by the presence of an acid catalyst.

FLOCRYLTM NMA is an ideal raw material for a wide variety of applications.
It is especially suitable for the preparation of latex binders and of cross-linkable emulsion polymers used in :

Adhesives
Antistatic agents
Chromatographic materials
Catalysts
Impregnation of non-woven fabrics
Inks
Paints
Paper coatings
Pasting agents
Plastics
Rubbers
Soil grouting systems
Textile finishes
Thermoplastics resins

When properly copolymerised, N-methylolacrylamide forms latices which have low viscosity and excellent shelf stability.
When the films, formed from these lattices, are cured, they develop excellent water resistance, organic solvent resistance, adhesion at high humidity and flexibility.

FLOCRYL NMA is a reactive monomer.
As with other such monomers, it must be stabilized to prevent polymerisation during shipping and storage.
FLOCRYL NMA can be safely handled if inhibited with cupric ions and oxygen, and if temperature, pH, and contamination are controlled.
Air is usually an adequate source of oxygen.

Oxygen
Dissolved oxygen is necessary to inhibit polymerisation of FLOCRYL NMA.
The dissolved oxygen level together with the air present is quite adequate stabilization during storage.
Controlled intermittent air flow or continuous sparging at 0.09 Nm3/hr per m3 of N-methylolacrylamide (0.2 SCFM per thousand gallons) is sufficient for inhibition purposes.

Temperature
FLOCRYLTM NMA should be controlled to between 0°C (32°F) and 30°C (86°F).
At temperatures below –10°C(14°F), N-methylolacrylamide will crystallize and separate from the solution.
Warming the product to 0°C (32°F) will re-dissolve the crystals.

In storage tanks, railcars and tank trucks, introduce tempered water (maximum temperature 40°C (104°F)) into the heating coils.
Packaged material should be moved to a warm environment until crystals are redissolved.
Do not apply steam to heating coils or direct heat to packaged material.
Hot spots must be avoided.
An air sparge should be employed, and agitation will increase the rate of dissolution.
At temperatures above 50°C (120°F), polymerisation could be initiated over time.
Storage tanks should include temperature monitoring and an independent temperature alarm system for early detection of polymerisation.

pH
As supplied, FLOCRYLTM NMA has a pH of 6.0 to 7.0.
Any modification of the pH, above or below these specifications can reduce the stability significantly.
Periodic monitoring of pH is recommended and, if necessary, the pH should be adjusted with either dilute sodium hydroxide or dilute sulfuric acid, or any other appropriate acids or bases.

Contamination
As with other reactive monomers, contamination of N-methylolacrylamide solutions with known initiators such as peroxides and azo compounds must be avoided.
Strong oxidizing agents such as persulfates can also initiate polymerisation of N-methylolacrylamide.
Reducing agents such as sulfites and bisulfites under certain conditions, can cause polymerisation.

Effect of light
N-methylolacrylamide is UV (ultra violet) sensitive.
Therefore, it should not be exposed to direct sunlight or polymerisation may occur.

N-methylolacrylamide (NMA) and N-methylolmethacryl-amide (NMMA) are important raw materials for the production of cross-linkable polymers by radical polymerization and for textile conversion. In the following discussion, only NMA will be mentioned, but all statements made for it apply equally to NMMA.
Processes for the production of NMA have long been known and all start from the reaction of acrylamide and formaldehyde.
They differ in the selection of the solvent, of the formaldehyde source, and of the active base used as the catalyst.
Since NMA is employed mainly in emulsion polymerization processes, aqueous NMA solutions are of special industrial importance and therefore, water is usually the preferred solvent in NMA production.

In textile industry, the binders used are mostly water based acrylic dispersions.
These binders provide strength, elastic recovery, soft hand, flexibility, color retention and also resistance to washing and aging to the textile and nonwoven.
Nevertheless, binders having no reactive functional monomers are not very successful in imparting these properties.
Self crosslinking monomers are used to improve the properties of textile and non woven end products.
N-methylolacrylamide (NMA) is one of these monomers having functional groups for self-crosslinking.
However, N-methylol acrylamide used in textile binders emit formaldehyde during crosslinking at high temperatures.
This formaldehyde either remains in the end product or is liberated into the air.
The U.S. Department of Health and Human Services published the 12th Report on Carcinogens and formaldehyde is listed in the category of known to be a human carcinogen.
Researchers on textile sector are focud on the subject of formaldehyde emission due to the harmfull effects on both people and environment.
In this study, a novel monomer that emmits no formaldehyde and have ability to self-crosslink was investigated for replacement of NMA and the performance results are compared with that of NMA.

AEROTEX NMA 48%, offered as a 48% aqueous solution, is a bifunctional monomer possessing both vinyl and hydroxymethyl groups.
Thermoplastic polymers can be formed through the copolymerization of NMA with a variety of vinyl monomers via emulsion, solution, or suspension techniques.
The resulting products, having pendant hydroxymethyl groups, are self-crosslinkable under moderate conditions.
This mechanism permits the conversion of thermoplastic backbone polymers to thermoset materials at the point of use without the need for an external crosslinker.
Conversely, the hydroxymethyl group can first be reacted with a substrate like cellulose and subsequently cross-linked by free radical polymerization.
