STATEMENT OF REASONS FOR ALLOWANCE
6	The following is an examiner’s statement of reasons for allowance:
The closest prior art of record (US 9,091,021 B2) teaches a method for dyeing cellulosic substrate, consisting of (a) cationizing a cellulose substrate (cotton) by applying a liquid composition comprising 2,3-epoxypropyltrimethylannonium chloride and applying a foam composition comprising dyes include fiber-reactive dyes, direct dyes or combination thereof (see claim 1). However, the closest prior art of record (US’ 021 B2) does not teach or disclose a process for cotton fiber cationization and cationic yarn dyeing comprising vinylsulfonic and monochlorotriazine type as claimed. Accordingly, the claimed subject as a whole would not have been obvious to one having ordinary skill in the art of cotton and yarn dyeing formulation.

APPLICANT REBUTTAL: REMARKS
Priority
Acknowledgment is made of applicant's claim for foreign priority based on an application filed on 01/11/2023. It is noted, however, that applicant has not filed a certified copy of the 000050-2023
application as required by 37 CFR 1.55.
The applicant is attaching a proper certified copy of the priority.Claim Objections
The examiner objected Claim 4 because of the following
informalities:
Claim 4, recites the term "CHPTAC". This term should be recited as "3-chloro-2-hydroxypropyltrimethylammonium chloride (CHPTAC)".
Appropriate correction is required.
Applicant   amended    claim   4   reciting  "3-chloro-2- hydroxypropyltrimethylammonium chloride (CHPTAC)".
Claim Rejections - 35 USC § 112
The Examiner rejected claims 2-4 and 6-17 under 35 U.S.C.
112(b) or 35 U.S.C. 112 (pre-AIA), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications
subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the
invention.
Claims 2-3 and 7-10 recite the term "approximately". The term
"approximately" is a relative term which renders the claims indefinite. The term "approximately" is not defined by the claim and the specification does not provide any guidance.
Claims 4, 6, 11-12 and 15-16 recite the phrase "preferably". The
phrase "preferably" renders the claims indefinite because it is unclear whether the limitations following the phrase are part of the claimed
invention. See MPEP 2173.05(d).
Claims 10-14 recite the limitation "spinning process". There is
insufficient antecedent basis for this limitation in the claims. Claim 1
does not recite "spinning process". Correction is required.
Claim 17 recites the limitation "peroxide removal process". There
is insufficient antecedent basis for this limitation in the claim. Claim 1
does not recite "peroxide removal process". Correction is required.
Applicant amended the claims in order to overcome the rejections under 112. No new matter was added.
Allowable Subject Matter
5    Claims 1, 5 and 18-22 are allowed. Claims 2-4 and 6-17 also would be allowed if the claims overcome the rejection under 112, second paragraph. The closest prior art of record (US 9,091,021 B2)
teaches a method for dyeing cellulosic substrate, consisting of (a)
cationizing a cellulose substrate (cotton) by applying a liquid composition comprising 2,3-epoxypropyltrimethylannonium chloride and applying a foam composition comprising dyes include fiber- reactive dyes, direct dyes or combination thereof (see claim 1). However, the closest prior art of record (US' 021 B2) does not teach or disclose a process for cotton fiber cationization and cationic yarn dyeing comprising vinylsulfonic and monochlorotriazine type as
claimed.
Applicant believes his application is now allowable and requests
an early favorable action.
Respectfully submitted,Albert Bordas, P.A.
