                                  EXHIBIT 10.28



June 6, 1997

Mr. William M. Dubay
President & Chief Operating Officer
Brunswick Technologies, Inc.
P.O. Box 516
Brunswick, ME 04011

Dear Bill:

Fleet Bank of Maine is pleased to renew a $2,500,000 working capital line of
credit to Brunswick Technologies, Inc. with Advanced Textiles, Inc. as
Guarantor. This letter, when properly signed and accepted, will constitute an
agreement between Fleet Bank of Maine of Portland, Maine (hereinafter referred
to as "Bank"), which agrees to lend, and Brunswick Technologies, Inc. of
Brunswick Maine and Advanced Textiles, Inc. of Seguin, Texas, (hereinafter
referred to as "Co-Borrowers") which agree to borrow, in accordance with the
following terms and conditions, in addition to those as outlined in the loan
documents:

BORROWER:  Brunswick Technologies, Inc.

GUARANTOR:  Advanced Textiles, Inc.

PURPOSE:  Short term working capital

MAXIMUM AMOUNT:  $2,500,000

INTEREST RATE: At the Borrower's option, either Fleet Bank of Maine's Prime
     Lending Rate (presently 8.50%) or the London Interbank Offered Rate plus
     1.75% for amounts of $100,000 or more for periods of 30 to 360 days,
     payable monthly and based on actual days outstanding over a 360 day year.

FEES:  1/8 of 1% on the unused portion, charged quarterly in arrears.

TERM:  On demand, with interest payable monthly. Subject to your continued
     favorable financial condition (in the sole judgment of the Bank) this line
     of credit is available for your use through May 31, 1998 and is subject to
     review prior to renewal.

Payments not made within 10 days of the due date will be assessed a late fee
     equal to 5% of the payment amount.

PREPAYMENTS/YIELD MAINTENANCE FEE ASSESSMENT: At any time that (i) the interest
     rate on the loan is a fixed rate and (ii) the Bank in its sole discretion
     should 




<PAGE>   2
     determine that current market conditions can accommodate a prepayment
     request, the Borrower shall have the right at any time and from time to
     time to prepay the loan in whole (but not in part), and the Borrower shall
     pay to the Bank a yield maintenance fee in an amount computed as follows.
     The current rate for United States Treasury securities (Bills on a
     discounted basis shall be converted to a bond equivalent) with a maturity
     date closest to the maturity date of the term chosen pursuant to the Fixed
     Rate Election as to which the prepayment is made shall be subtracted from
     the "Cost of Funds" component of the fixed rate in effect at the time of
     prepayment. If the result is zero or a negative number, there shall be no
     yield maintenance fee. If the result is a positive number, then the
     resulting percentage shall be multiplied by the amount of the principal
     balance being prepaid. The resulting amount shall be divided by 360 and
     multiplied by the number of days remaining in the term chosen pursuant to
     the Fixed Rate Election as to which the prepayment is made. Said amount
     shall be reduced to present value calculated by using the number of days
     remaining in the designated term and using the above referenced United
     States Treasury security rate and the number of days remaining in the term
     chosen pursuant to the Fixed Rate Election as to which the prepayment is
     made. The resulting amount shall be the yield maintenance fee due to the
     Bank upon prepayment of the fixed rate loan. Each reference in the
     paragraph to "Fixed Rate Election" shall mean the election by the Borrower
     pursuant to the paragraph labeled "Interest Rate" in this Agreement.

MINIMUM ADVANCES:  Advances under the Line will be subject to a minimum advance
     of $5,000 per request.

REPORTING: The Borrower shall submit to the Bank the following reports and such
     other as the Bank may request without limitation:

         (a) Borrower's quarterly 10Q reports submitted within 45 days of the
         end of each quarter.

         (b) Borrower's annual audited and consolidated financial statement
         (with consolidating schedules) to include its 10K report within 120
         days of year-end prepared by a certified public accountant acceptable
         to the Bank.

         (c) Quarterly covenant compliance certificates, within 45 days of
         quarter-end.

     previously delivered to it fairly presents the business and financial
